Full textCe travail porte sur la production d’élastomères thermoplastiques basés sur un polymère thermoplastique (le polyéthylène de basse densité, LDPE) et un caoutchouc naturel (NR) recyclé provenant de pneus usés (ground tire rubber : GTR). Les échantillons ont été moulés par rotomoulage en utilisant deux méthodes de mélange : à l'état fondu par une extrudeuse bi-vis et par un mélange à sec en utilisant un mélangeur haute intensité afin de comparer l’effet du cisaillement et de l’histoire thermo-mécanique sur les propriétés mécaniques et physiques des composés. De plus, deux types de caoutchouc naturel recyclé ont été utilisés. Le premier est une matière recyclée provenant directement des pneus hors-route (off-the-road, OTR) par réduction de taille et le second est le même matériel ayant subi un procédé de régénération à l’échelle industrielle. Dans chaque cas, trois concentrations de caoutchouc ont été utilisées (20, 35 et 50% en poids) pour comparer avec les propriétés de la matrice seule (0%). Le travail a permis de déterminer l’effet des paramètres de mise en oeuvre comme le temps de chauffage, la température du four, le rapport de vitesse et la taille des particules pour optimiser le procédé rotomoulage. À partir des échantillons obtenus, une caractérisation morphologique (microscopie), physique (densité et dureté) et mécanique (tension, flexion et impact) a été effectuée. Les résultats ont montré que l'augmentation de la concentration en caoutchouc diminuait la rigidité et la résistance mécanique, mais augmentait l'élasticité et la ductilité. Finalement, bien que le mélange à l'état fondu a donné des propriétés légèrement supérieures au mélange à sec, ce dernier est intéressant afin de limiter la dégradation thermo-mécanique et oxydative des matériaux tout en réduisant les coûts et le temps de fabrication.
This project focuses on the production and characterization of thermoplastic elastomers, based on a thermoplastic polymer (low density polyethylene, LDPE) and recycled natural rubber (NR), obtained from ground tire rubber (GTR). The samples were rotomolded by two blending techniques: melt blending by twin-screw extrusion, and dry blending using a high speed mixer to study the effect of shear and thermo-mechanical history on the physical and mechanical properties of the compounds. Also, two types of recycled natural rubber were used in this study. The first one is a recycled material, obtained from off-the-road (OTR) tires after size reduction. On other hand, the second one is the same material which underwent a regeneration process at industrial scale. In each case, three rubber concentrations (20, 35, 50 wt.%) were used to compare with the properties of the neat polymer. In addition, the effect of several parameters such as: heating time, oven temperature, speed ratio of the rotating arms, and particle size is studied to optimize the rotomolding process. Then, from the samples produced, morphological (optical and scanning electron microscopy), physical (density and hardness) and mechanical (tension, flexion and impact) characterizations were performed. Based on the results obtained, it was shown that increasing the rubber concentration led to lower rigidity and mechanical strength, but higher elasticity and ductility. Finally, although the melt blending method provides better properties than the dry blending one, the latter is interesting to limit the thermo-mechanical and oxidative degradation of the materials, as well as reducing the costs and manufacturing time.

Full textLow density polyethylene (LDPE) is one of the synthetic polymers most used and the prediction of its rheological behavior is an industrial stake. The difficulty lies in the complex architecture of the molecules. The number, the size and the position of the branches are random and these parameters have major effects on the rheological behavior. This work shows that the real structure of LDPE can be sketched by an irregular Cayley tree. The structural parameters can be determined from SEC measurements and from the kinetics of free radical polymerization. Based on this picture of the molecules, a molecular model is proposed to describe the dynamics of the LDPE in the case of a monodisperse samples and polydisperse samples. The linear viscoelastic behavior of our LDPE was correctly predicted. The strong link between structure and rheology enables to solve the inverse problem. Linear viscoelastic data contain all the structural information. The use of the molecular model and an algorithm of minimization leads to an average structural picture of the molecules very close to that obtained by SEC. This average structure was transformed into "pom-pom" structures that were used in an "pom-pom" multimode constitutive equation. The calculated transient viscosity of our LDPE agrees with experimental measurements both in shear and uniaxial elongational flow
