废轮胎胶粉力化学改性研究

利用开炼机和转矩流变仪以及塑解剂对废轮胎胶粉进行力化学改性研究。结果表明：废轮胎胶粉经开炼机或转矩流变仪处理后，塑性变形能力增强，转矩流变仪的改性效果更好；采用开炼机处理废轮胎胶粉时，加入塑解剂RP66或9023/WG对改性效果影响不大；采用转矩流变仪处理废轮胎胶粉时，处理温度升高，会使改性效果降低，加入塑解剂RP66或9023/WG对改性效果影响明显，塑解剂9023/WG的改性效果更好。;The ground tire rubber was modified by mechanochemistry method with peptizer by using mill or torque rheometer.The results showed that， in mill or torque-rheometer，the plastic deformation performance of modified ground tire rubber was enhanced， and the modifying effect of torque rheometer was better.In the mill，addition of peptizer RP66 or 9023/WG had little influence on the modification.In torque-rheometer，the modifying effect decreased with the increase of temperature，but it was obviously improved by adding peptizer RP66 or 9023/WG，and the modifying effect of peptizer 9023/WG was better
