摘要
采用硫黄硫化体系和过氧化物（硫化剂DCP）硫化体系对EPDM／NR并用胶实施复合交联，研究并用比和复合交联体系对胶料的硫化特性、物理性能和耐热老化性能的影响。结果表明，在大部分并用比下，复合交联可以改善胶料的硫化特性；在硫化剂DCP和助交联剂TAIC的用量均为2份、EPDM／NR／ENR并用比为30／68．5／1．5时，并用胶的物理性能优良；以NR为主的并用胶在复合交联时硫化剂DCP和助交联剂TAIC的用量宜取1～2份。
The EPDM/NR blends were multiplex cross-linked with sulfur and peroxide（DCP） curing system. The influence of the EPDM/NR blending ratio and the multiplex curing system on the cu- ring behavior, physical properties and heat aging property of blends was investigated. The results showed that with most blending ratios,the curing behavior was improved by multiplex cross-linking;a blend with excellent physical properties was obtained by using 30 EPDM/68.5 NR/1.5 ENR with 1-2 phr curing agent DCP and secondary curing agent TAIC.
