The Impact

Abstract Thermoplastic composites containing different Ground Rubber Tire (GRT) materials, Linear Low Density Polyethylene (LLDPE) and, in some case, a coupling agent (IB‘E’, an ethylene glycidyl methacrylate copolymer) were prepared by melt blending. The impact energies of all the thermoplastic composites (normally containing 40 wt % GRT) were evaluated using an instrumented impact tester. The effects of the GRT particle-size, particle size distribution and shape, the mode of grinding, and the oxygen surface concentration were analyzed. The wet-ambient-ground GRT based composites show higher surface oxidation and give better impact energy than cryo-ground and normal air-ground GRT based composites. Smaller GRT particle size results in a small increase in the impact property of the composite and a greater influence on the melt processability of the composites. Of the different GRT surface modification techniques studied for improved composite interfacial adhesion and impact properties the composites from electron beam radiation treated GRT yield higher increases in impact energy in comparison to corona and plasma treated GRT based composites.

Abstract Ground rubber tire (GRT) particles of different sizes were characterized and the effect of these particles in a natural rubber (NR) compound was studied. It is found that smaller particles contain less polymer, but have higher amounts of fillers and metals with respect to polymer. NR compound containing smaller GRT particles shows better physical properties, but poorer aging characteristics.

The graft copolymerization of maleic anhydride (MAH) onto ground rubber tire (GRT) was investigated through solvothermal synthesis route using free radical initiator. The effects of solvents, initiators and their concentration, and GRT mesh size on the grafting yield (GY) were studied, and the optimal conditions were concluded. The results showed that the high GY was obtained by using toluene as solvent, 1% azobisisobutyronitrile as initiator, and GRT fine powder as raw material. Infrared spectra and X-ray photoelectron spectra confirmed that MAH was successfully grafted onto the GRT molecules. The thermogravimetric analysis revealed that the thermal stability of graft GRT (GRT-g-MAH) is better than that of GRT slightly. The blending experimental results suggest that the GRT-g-MAH can be used as a compatilizer for GRT/HDPE blends.
