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,考察了不同共混比EPDM/NR共混胶的硫化特性、硫化胶的物理机械性能、耐水性及耐溶剂性能。结果表明:复合交联后,胶料的硫化特性、物理机械性能均有所提高;EPDM母炼胶中DCP的用量要高于NR;胶料共混比为80/20(EPDM/NR),其耐水性和耐溶剂性能达到最佳。The EPDM/ NR blends were multiplex cross-linked with sulfur and peroxide（DCP） curing system.The curing behavior,physical properties,water and solvent resistence based on the different EPDM/NR blending ratios were investigated.The results showed that with most blending ratios,the curing behavior was improved by multiplex cross-linking;the peroxide（DCP）dosage used in EPDM was more than used in NR,the most EPDM/NR blending ratio was 80/20 when its water and solvent resistence performance were excellent.
