Abstract:

In order to improve the bonding performance, EVA composite hot melt adhesives were prepared by introducing crosslinking agent and silane coupling agent in this paper. A binary EVA resin blend as the base resin with appropriate viscosity and tensile shear strength was selected as hot melt adhesive. The effects of crosslinking agent and silane coupling agent on the properties of ethylene/vinyl acetate (EVA) composite hot melt adhesive were studied. By investigating the preparation and curing conditions of hot melt adhesive and the properties of hot melt adhesive after the introduction of dicumyl peroxide (DCP), the optimum temperature and dosage of DCP and its influence on the properties were determined. It was found that the tensile shear strength of hot melt adhesive increased from 0.247 MPa to 0.726 MPa when 2 phr DCP and 5 phr KH570 were added at the same time. The tensile strength and tensile shear strength of hot melt adhesive are only slightly improved when silicone coupling agents with different functional groups are added to EVA composite hot melt adhesive. However, it was found that excessive silane coupling agent would significantly reduce the tensile strength and shear peel strength of the material.

Abstract:

This study develops hot melt pressure sensitive adhesives (HMPSAs) for the seamless bonding of nylon fabric, using butyl acrylate as the main monomer material and mixing the functional monomer for polymerization. It is combined with 2-10phr diphenyl (2,4,6-trimethylbenzoyl) phosphine oxide for the photoinitiator and ultraviolet irradiation is used to make a pre-polymer. The effects of butyl acrylate content, type of functional monomer, and 2-10phr diphenyl (2,4,6-trimethylbenzoyl) phosphine oxide content on the molecular weight of acrylate pre-polymer are discussed, following the Taguchi method. The pre-polymer is then mixed with the reactive diluent glycidyl methacrylate blend and with 2-10phr diphenyl (2,4,6-trimethylbenzoyl) phosphine oxide, coated on a release film, irradiated by ultraviolet light, and cured into hot melt pressure sensitive adhesives. The adhesive properties of hot melt pressure sensitive adhesive bonding on nylon include the peel strength, the shear strength, adhesive warpage, adhesive color difference, and adhesive overflow, which are discussed following the Taguchi method and the elimination and choice translating reality method for multi-quality analysis. Hot melt pressure sensitive adhesives are implemented by optimization parameters for practical validation. The results show that the peel strength of hot melt pressure sensitive adhesives is 1.495 kg/cm, the shear strength of hot melt pressure sensitive adhesives is 14.326 kg/cm2, adhesive warpage is 0.93 mm, adhesive color difference is 1.66, and adhesive overflow is 0.97 mm. The performance of HMPSAs in this study is enhanced effective.

Abstract:

Hot melt adhesive synthesized using polymerized fatty acid (PFA) (composition: ~1% trilinoleic acid, ~97% dilinoleic acid and ~2% linoleic acid) and ethylenediamine was blended with nylon-6, in-situ during the synthesis process to improve its performance properties. Nylon-6 was added in concentrations as 5, 10, 15 and 20 phr in the hot melt adhesive. The prepared blends were characterized for thermal (melting temperature, crystallization temperature, enthalpy of melting and enthalpy of crystallization), mechanical (tensile strength, tensile modulus, stiffness, percentage elongation at break and hardness), adhesion (lap shear strength and T-peel strength) and rheological properties. It was found that the viscosity, tensile strength, tensile modulus, stiffness, hardness, melting temperature, enthalpy of melting, crystallization temperature and enthalpy of crystallization increased with increase in concentration of nylon-6 in the hot melt adhesive. But lap shear strength and T-peel strength increased up to 10 phr concentration of nylon-6 above which both started decreasing. Percentage elongation at break decreased with increase in concentration of nylon-6 in the hot melt adhesive. Hot melt adhesive molecules must have oriented themselves about nylon-6, increasing its crystallinity, and thus the strength of the adhesive.

Abstract:

We present a case wherein hot-melt adhesive was injected into the finger using a high-pressure industrial glue gun. Unlike hot-melt adhesive contact burns, hot-melt adhesive is hard to remove when it is injected with a high-pressure glue gun, resulting in more severe injury. In our case, initial treatment was not adequate because the patient did not mention any unusual symptoms and the lesion itself did not show any unusual findings. Moreover, because of the absence of symptoms like pain, the patient attended an outpatient visit later than on the scheduled date. As a result, skin necrosis occurred. Surgery was performed to excise the necrotic tissue and remove hot-melt adhesive foreign bodies. One month after the surgery, the wound had completely healed without any complications. The aim of this case report is to highlight the damage associated with high-pressure hot-melt adhesive injection injury, which we believe is not sufficiently perceived by the naked eye. The characteristics of the injected material must be identified at first. And immediate surgical intervention is needed.

Abstract:

AbstractHot-melt adhesives facilitate fast production processes because the adhesives set simply by cooling. Formulations contain polymers to provide strength and hot tack (resistance to separation while adhesive is hot), and tackifiers and/or oils to dilute the polymer entanglement network, adjust the glass-transition temperature, lower the viscosity, and improve wet-out (molecular contact of the adhesive with the substrate over the entire bonding area). Some adhesives also contain waxes to speed setting, lower viscosity, and improve heat resistance. Obtaining adequate strength and heat resistance from nonreactive hot melts requires that some component of the hot melt separate out into a dispersed but interconnected hard-phase network upon cooling. The hard phases are commonly either glassy styrene domains (for adhesives based on styrenic block copolymers) or organic crystallites (for adhesives based on waxes, olefinic copolymers, or ethylene copolymers). This article will describe first the material properties relevant to the processing and performance of hot-melt adhesives, then the chemistry and function of the specific raw materials used in hot melts, and will conclude with illustrative application examples and corresponding formulations.

Abstract:

An end-type fiber-optic UV sensor based on the principle of fluorescence is proposed and demonstrated. The sensor is made of large-core plastic optical fiber with one end covered with mixture of hot melt adhesive and small amount of chlorophyll. As sources of ultraviolet radiation solar simulator and UV lamp are used. Spectra on the sensor output are measured with spectrometer and compared for different UV light sources. Both hot melt adhesive and chlorophyll reacted to UV radiation. The peaks of fluorescent emission are obtained in visible spectrum in range of blue wavelengths (for hot melt adhesive) and in range of red wavelengths (for chlorophyll), which makes this sensor configuration a good solution for signal multiplexing.

Abstract:

The quality of modes of 3PE heat shrinkable sleeve is determined by tackiness of hot melt adhesive rather than aging, according to TGA and aging tests. The tackiness of hot melt adhesive influences on pipeline remaining life and the transmission safety of oil or gas. This paper mainly discussed how the tackiness is determined by hot melt adhesive moisture performance which depends on melt rheology and polymer polarity and offer basic information to further modification. Finally, this paper offers a choice data after such follow experiment. About rheology, apparent viscosity was tested by capillary rheometer and tackiness strength was measured by universal material testing machine. Those tests show that Eτ (Fe/Fe) raises and Ep(Fe/PE) increases at first then decreases with apparent viscosity increasing. About polarity, the polarity was tested by dynamic contact angle locator. This measurement indicates that the moisture improves with polarity increasing and tackiness increases at same time. Generally, the hot-melt adhesive apparent viscosity and polarity extend, consider to pipeline materials properties and oil or gas transmission condition, should hold at 450 Pa•s≤ηa (100°C ,20kg)≤520 Pa•s and 82.0°≤γ≤90.6°.

Abstract:

In the present study, we used tensile shear tests, Shore hardness tests, differential scanning calorimetry (DSC), and thermogravimetry (TGA) to characterize a reactive polyurethane-based hot melt adhesive. We also measured contact angles at various temperatures to evaluate the wettability of the adhesive and to determine the optimum temperature range for applications. The adhesive was tested following curing for various times, and the bonding of the adhesive with several materials was investigated to determine whether it has the potential for greater versatility of application. Therefore, we explored new uses of the adhesive, such as in the matrix of a composite with fiberglass. Reactive hot melt adhesives are useful because they provide a certain degree of flexibility to joints, and have high processing speeds, high initial rigidity, and high working temperatures.

Abstract:

The thermoplastic polyurethane elastomer (TPU) was firstly synthesized by using polybutylene adipate (PBA) as soft segments, methane-4-4’-diisocyanate(MDI) and 1,4–butanediol(BDO) as hard segments. The polyurethane hot-melt adhesive was then prepared by adding the tackifying resin, filler and other auxiliaries into the TPU matrix. The structure of the synthetic products was characterized by Infrared Spectrum and the thermal properties and microstructure of polyurethane hot-melt adhesive was tested by the thermogravimetric(TG) and the scanning electron microscopy(SEM), respectively. The results showed that the thermoplastic polyurethane elastomer had the expected structure, the shear strength of polyurethane hot-melt adhesive increased with the pentaerythritol abietate content increasing when the addition of the pentaerythritol abietate is less than 20 wt%, and decreased with the content of CaCO3 filler and petroleum resin increasing, respectively; the thermal stability was improved, and the char yields of the polyurethane blends increased with adding the filler CaCO3. When the molar ratio of PBA:MDI:BDO was 1:2:1, the addition of pentaerythritol abietate and filler CaCO3 was 20 wt% and 30 wt%, the comprehensive performance of PU hot-melt adhesive was better and the shear strength was 7.37 MPa.

Abstract:

In this paper, the compound hot-melt adhesives were prepared by blending alkyl sulfonate polymer antistatic agent with modified rosin hot-melt adhesive and used for the preparation of polyethylene film/polypropylene-coated non-woven fabrics. The effects of the amount of antistatic agent on the melt viscosity, softening point, and thermal stability of the compounded hot-melt adhesives were studied. Then, the antistatic properties and its washing fastness of the coated non-woven fabrics were tested and analyzed. The results showed that the softening point and the melt viscosity of the hot-melt adhesives decreased after compounding, and the thermal stability of the compound hot-melt adhesives decreased in the high temperature range, which was not affected before 200℃. The surface inductive voltage, half-life, and specific resistance of the coated non-woven fabrics prepared from the compound adhesives decreased gradually with the increase of the amount of the antistatic agent, indicating that the antistatic property of the prepared fabrics was gradually improved. In addition, the fabrics still exhibited antistatic properties after soaping for several times. The influence of compound adhesive on the wettability of fabric surface was consistent with that of antistatic property. Finally, the mechanism of the hot-melt adhesive and antistatic agent compounding technology to improve the antistatic performance of the coated non-woven fabrics was elaborated, and the reason for its excellent soaping durability was also explained.

Abstract:

A procedure is described of grafting the acrylic acid onto an oxygen/ozone-activated metallocene poly(ethylene-co-propylene). Consequently, the grafted copolymer is applied as a component in a metallocene polyolefin-based hot-melt adhesive composition with increased adhesion. The surface properties and adhesion strength of the prepared hot-melt adhesive (HMA) were determined and used to account for the effect of grafting. The application of grafted polyolefin as one of the components of the HMA mixture provides significant increase in adhesive strength, and it also results in increased compatibility and negligible effects on the technological parameters of the final composition. The obtained results may have significant impact for the practical application of prepared HMA for book bonding.

Full text

Abstract:

Polyhydroxyalkanoate (PHA), with a long chain length and high poly(4–hydroxybutyric acid) (P4HB) ratio, can be used as a base polymer for eco-friendly and biodegradable adhesives owing to its high elasticity, elongation at break, flexibility, and processability; however, its molecular structures must be adjusted for adhesive applications. In this study, surface-modified cellulose nanofibers (CNFs) were used as a hydrophobic additive for the PHA-based adhesive. For the surface modification of CNFs, double silanization using tetraethyl orthosilicate (TEOS) and methyltrimethoxysilane (MTMS) was performed, and the thermal and structural properties were evaluated. The hydrophobicity of the TEOS- and MTMS-treated CNFs (TMCNFs) was confirmed by FT-IR and water contact angle analysis, with hydrophobic CNFs well dispersed in the PHA. The PHA–CNFs composite was prepared with TMCNFs, and its morphological analysis verified the good dispersion of TMCNFs in the PHA. The tensile strength of the composite was enhanced when 10% TMCNFs were added; however, the viscosity decreased as the TMCNFs acted as a thixotropic agent. Adding TMCNFs to PHA enhanced the flowability and infiltration ability of the PHA–TMCNFs-based adhesive, and an increase in the loss tangent (Tan δ) and adjustment of viscosity without reducing the adhesive strength was also observed. These changes in properties can improve the flowability and dispersibility of the PHA–TMCNFs adhesive on a rough adhesive surface at low stress. Thus, it is expected that double-silanized CNFs effectively improve their interfacial adhesion in PHA and the adhesive properties of the PHA–CNFs composites, which can be utilized for more suitable adhesive applications.

Abstract:

ABSTRACT Restoring a complex occlusal morphology of the posterior teeth is tremendously difficult when direct composite resin restorative materials are used because carving of the solid polymerized mass is accomplished mechanically using rotary instruments. The preoperative occlusal morphology of the tooth provides for the preparation of an ideal index of the esthetic and functional anatomy in cases where the carious lesion is confined within a shell of undermined yet intact enamel, and is registered using a transparent hot melt adhesive (HMA) material. The registration is then used as an index to reproduce the occlusal morphology in the final incremental restorative layer during the composite resin restoration, which also allows for the photopolymerization of the restoration through the translucent index.

Abstract:

Hot-melt pressure-sensitive adhesive (HMPSA) is an environmentally benign adhesive which is typically processed without solvent in industries. However, casting solution method is commonly used for experimental purposes in the lab for convenience. Therefore, seven types of solvent with different polarities, including toluene as the most commonly used solvent, were investigated in this work to study the feasibilities. Quick bond strength and holding power were tested with different types of solvents and different adhesive weight percent in the prepared solutions. Through viscosity measurement, thermal analysis, and compositional analysis, the correlation between the chosen solvents and adhesive performance was further explored. It was found that the differences in the obtained bond strength of HMPSA treated with a variety of solvents were due to physical reasons instead of chemical reactions, and a solvent with similar polarity to toluene (e.g., tetrachloride, octane) should be considered as an option because a similar polymer chain relaxation could be maintained as the original HMPSA without solvent treatment. In this study, the mechanism of choosing toluene as common solvent for HMPSA testing was analyzed, and the feasibility of optional solvents was discussed.

Abstract:

Using the IR-thermography methods, the experimental evaluation of temperature transitions in a steel and aluminum glue-welded joint made with applying various adhesive materials (epoxy, anaerobic, organic-silicon and hot melt glue) has been carried out. It was found out that viscosity of an adhesive material considerably effected on the temperature transitions in the glue-welded joint as well as on glue line thickness. The temperature transitions were demonstrated on different sections of the glue-welded joint. Conclusions were made about the influence of properties of adhesive materials on the glue-welded joint quality.

Abstract:

For the bonding of the lightweight composite parts, it is desired to apply electrically conductive adhesive to maintain the ability to shield electromagnetic interference. Among various solvent-based adhesives, there is a new group of thermoplastic hot melt adhesives that are easy to use, solidify quickly, and are environment-friendly. To make them electrically conductive, a copolyamide-based hot melt adhesive was mixed with 5 and 10 wt% of carbon nanotubes using a melt-blending process. Well-dispersed nanotubes, observed by a high-resolution scanning microscope, led to the formation of a percolated network at both concentrations. It resulted in the electrical conductivity of 3.38 S/m achieved for 10 wt% with a bonding strength of 4.8 MPa examined by a lap shear test. Compared to neat copolyamide, Young’s modulus increased up to 0.6 GPa and tensile strength up to 30.4 MPa. The carbon nanotubes improved the thermal stability of 20 °C and shifted the glass transition of 10 °C to a higher value. The very low viscosity of the neat adhesive increased about 5–6 orders of magnitude at both concentrations, even at elevated temperatures. With a simultaneous growth in storage and loss modulus this indicates the strong interactions between polymer and carbon nanotubes.

Abstract:

Influence of collagen modifications on qualitative parameters of thermoplastic adhesive mixtures and its microbiological stability.This work presents the possibility to use the modified biopolymer collagen for preparation of ecologic, biologically degradable thermoplastic adhesives. Collagen prepared from secondary raw materials of the leather and food industry was applied as a starting material for the preparation of thermoplastic, formaldehyde-free adhesives intended for use in woodworking, furniture and paper industries. Glued joint obtained high strength and flexibility after application of modification plasticisation agents based on collagen. Modifications of collagen glue with keratin biopolymer increased its resistance to water and the strength of the glued joint. Prepared samples of hot-melt adhesive had higher bonding strengths than standard commercial adhesives. The highest tensile strengths were achieved by applying of undiluted adhesive with the application of 2.5% keratin hydrolysate into hot-melt adhesive. As collagen is a natural polymer easy biodegradable in the aquatic environment, the research has focused on the possibility of its microbiological stabilization with aqueous solutions of ionic and colloidal silver. The highest microbiological activity was observed in a sample of ionic silver sulphate solution with a concentration of 2000 ppm Ag+. Its 1% concentration was applied for antibacterial thermoplastic stabilization of formaldehyde-free collagen glue.

Abstract:

A hot melt adhesive – mainly used for bonding plastic component in automotive field – was modified with different iron-based particles to give it a reversible behaviour. Mechanical and physical properties of these reversible adhesives were experimentally assessed in the work. The modified adhesives, coupled with electromagnetic induction, are able to guarantee separation of the joints without any damage to the substrates for recycling, reuse or repairing of components. Single lap joint specimens were prepared using epoxy/glass fibres substrates and tests were carried out on neat and modified adhesive with 5% weight of iron and iron oxide. Three different Fe particles size were tested: 450 µm, 60 µm and 1–6 µm. The particles size of iron oxide was 50 nm. Separation was studied using single lap joint specimens under electro-magnetic induction. Experimental results showed that the maximum peak load decreases when the average particles sizes increase. The peak loads of the smallest particles were equal to the ones of the pristine adhesive. The elongation of the adhesives increases when the adhesive is modified with both iron and iron oxide particles. Finally, experimental tests on single lap joints coupled with electro-magnetic induction showed that separation of the substrates is possible using iron oxide particles. Electro-magnetic tests conducted on particles alone, helped to understand that bigger particles are able to overcome the melting temperature of the adhesive but hot-melt adhesives modified with these particles are not able to reach the melting. These tests showed that the number of particles into the adhesive matrix is very important for this kind of tests.

Abstract:

Hot-Melt Adhesives (HMAs) are typically used in applications where instant sealing is critically required. HMAs are generally preferred for those applications where processing speed is critical. These materials are widely used in various engineering applications, mainly as sealants in leakages and crack filling of walls and roofs. The industrial use of HMAs is most common in glassware and automobiles for gluing glasses in buildings and bonding heavy motor parts. The formulation of HMAs contains a polymer of suitable nature that makes the base for a strong adhesive, and waxes are added to increase the settling time of adhesive. The tackifiers are used to dilute the polymer to adjust the Glass Transition Temperature (Tg) and to reduce the viscosity for proper flow of hot-melt. This review intends to comprehensively discuss the preparation and formulations of HMAs using various polymer matrices, along with their applications and mechanics. The designing of green HMAs has been discussed in the literature and have been promoted over conventional solvent-based HMAs due to their functionality without Volatile Organic Compounds (VOCs). Various measures, challenges, and resolutions for making hazard-free HMAs have been discussed in the present review.

Abstract:

Asphaltene/resin blend (ARB) extracted from heavy crude oil was used to modify poly(styrene-block-isoprene-block-styrene) (SIS) to make it an adhesive. There were prepared double and triple mixtures containing 10–60% SIS, 10–40% ARB, and 10–50% naphthenic oil used as an additional plasticizer. The viscoelasticity of the mixtures at 25 °C and 120 °C was studied, their flow curves were obtained, and the temperature dependences of the loss tangent and the components of the complex modulus were measured. In addition, the mixtures were used as hot-melt adhesives (HMAs) and pressure-sensitive adhesives (PSAs) in the shear, peel, and pull-off tests of the adhesive bonds that they formed with steel. Both naphthenic oil and ARB act as plasticizers for SIS and make it sticky. However, only the combined use of ARB and the oil allows for achieving the best set of adhesive properties of the SIS-based mixture. High-quality HMA requires low oil content (optimal SIS/ARB/oil ratio is 50/40/10, pull-off adhesion strength (τt) of 1990 kPa), whereas a lot of the oil is needed to give SIS characteristics of a PSA (SIS/ARB/oil is 20/40/40, τt of 100 kPa). At the same time, the resulting PSA can be used as a hot-melt pressure-sensitive adhesive (HMPSA) that has many times lower viscosity than HMA (13.9 Pa·s versus 2640 Pa·s at 120 °C and 1 s−1) but provides a less strong adhesive bond (τt of 960 kPa).
