【摘要】 研究了橡胶种类及用量、增塑剂用量、表面处理剂种类及用量对聚氯乙烯/橡胶非硫化复合体系力学性能的影响,并用扫描电镜分析了有机胺类表面处理剂改性高岭土/聚氯乙烯/丁腈橡胶的界面结合状况。结果表明,当丁腈橡胶(NBR)用量为30份,增塑剂DOP用量为60份,表面处理剂1质量分数为3%,并且填有60份的高岭土时,可得到力学性能较佳的高岭土/聚氯乙烯/丁腈橡胶共混物。更多还原

【Abstract】 The effects of the category and content of rubber,the content of plasticzer,and the category and content of surface treating agent on the mechanical properties of PVC/rubber unvulcanized blend were studied.SEM was applied to the analysis of the interfacial bonding of the kaolin clay/PVC/NBR surface treated and modified by organic ammonia.The results showed when the content of NBR was 30 phr,the content of DOP was 60 phr,the mass fraction of Surface Treating Agent 1 was 3%,and the content of kaolin clay was 60 phr,the mechanical properties of kaolin clay/PVC/NBR unvulcanized blends were the optimum.更多还原
