| 摘 要： | 采用动态硫化的方法制备了三元乙丙橡胶(EPDM)/高聚合度聚氯乙烯(HPVC)热塑性弹性体.考察了PVC聚合度、橡塑比、增塑剂添加量、硫化剂用量(质量分数)及不同促进剂配比对体系性能影响,研究了动态硫化工艺条件(硫化时间和硫化温度)对体系性能的影响.实验结果表明:采用动态硫化方法,选用HPVC、橡塑比为30/70、DOP用量为35份、硫化用量为0.4份及适当促进体系,在动态硫化温度为170研口硫化时间为6min条件下,制得性能优良的EPDM/HPVC热塑性弹性体,其拉伸强度能达到15.18 MPa,断裂伸长率能达到544%.

| Abstract: | TPE can be acted as a substitute of rubber in many applications. This paper investigates the Ethylene-Propylene-Diene Monomer /Polyvinyl chloride(EPDM/HPVC) thermoplastic elastomer manufactured using dynamic vulcanization process. The study focuses on the effects on the mechanical properties of EPDM/HPVC TPEs from the PVC's polymerization degree,the ratio of rubber to plastics,the plasticizer's dosages,the sulfur content,and the different curing accelerant content. Also,the impact of curing conditions on th... |
