摘　　要：根据粘度相近共混原则,通过(乙烯/丙烯/二烯)共聚物(EPDM)充油、筛选高流动性的粉状聚丙烯(PP)、添加超细活性滑石粉等方法,使EPDM与PP充分均匀分散;采用动态硫化法在单螺杆挤出机组上制备了完全交联的EPDM/PP共混型热塑性弹性体(TPV);用SEM、力学测试、布拉本流变仪等实验方法,探讨了TPV的配方组成、工艺条件与性能的关系;摸索了TPV的加工性;研究了TPV对PP的增韧效果,发现TPV能大大改善PP的综合性能。The rule of close viscidity blend was adopted, by using of filling oil EPDM, high fluidity PP, and super-fine talcum powder, TPV was prepared in single-screw extruders by dynamic vulcanization. The relationship of TPV properties, melt blending temperature and composition were studied by SEM, mechanical tests and dynamic rheological test. The process and toughening effect of TPV on PP were discussed. The results showed that TPV could greatly improve the comprehensive properties of PP.
