助交联剂PDM和硫黄用量对CM/EPDM并用胶性能的影响

试验研究在过氧化物硫化体系下助交联剂N，N′-间亚苯基双马来酰亚胺（PDM）和硫黄用量对氯化聚乙烯橡胶（CM）/EPDM并用胶性能的影响。结果表明：在硫化剂DCP/助交联剂PDM硫化体系下，当硫化剂DCP用量为3份、助交联剂PDM用量为1.5～2份时，CM/EPDM并用胶的综合性能较好;在硫化剂DCP/硫黄硫化体系下，当硫化剂DCP用量为3～4份、硫黄用量为0.3～0.4份时，CM/EPDM并用胶的综合性能较好。;The influence of addition levels of secondary curing agent PDM and sulfur for peroxide curing system on the properties of CM/EPDM blends was experimentally investigated.The results showed that,by using DCP/PDM curing system,the comprehensive properties of CM/EPDM blend were better when 3 phr DCP and 1.5～2 phr PDM were respectively used;by using DCP/sulfur cuing system,the comprehensive properties of CM/EPDM blend were better when 3～4 phr DCP and 0.3～0.4 phr sulfur were respectively used
