Thermochemical compatibilization of reclaimed tire rubber/ poly(ethylene-co-vinyl acetate) blend using electron beam irradiation and amine-based chemical

Abstract Waste tire rubber is commonly recycled by blending with other polymers. However, the mechanical properties of these blends were poor due to lack adhesion between matrix and waste rubber. In this research, use electron beam irradiation (3-Aminopropyl)triethoxy silane (APTES) on enhancing performance 50 wt% reclaimed (RTR) blend poly(ethylene-co-vinyl acetate) (EVA) was investigated. Preparation RTR/EVA carried out in internal mixer. The then exposed (EB) at doses ranging from 200 kGy. APTES loading varied 1 10 wt%. processing, morphological, mechanical, calorimetric stabilization torque total mixing energy higher compatibilized blends. Mechanical improved efficiency further reclaiming RTR compatibilizing dispersion embedded smaller particles EVA crosslinking Calorimetric studies showed increased crystallinity which corresponds properties. ductility decreased interaction APTES.
