摘　　要：采用硫磺硫化体系对EPDM/NR再生并用胶实施交联,研究了其不同配比对胶料的硫化特性、力学性能、耐热老化性能和粒子分散性的影响。结果表明,在多数并用比下,共混胶都达不到良好的共硫化。当EPDM/NR再生胶以70/30比例并用时,硫化胶具有最佳的力学性能和良好的粒子分散性。When sulfur curing system was used for EPDM and reclaimed natural rubber blends,the effects of different ratios on curing characteristics,mechanical properties,anti-aging properties and particle dispersion were studied.It was shown that vulcanization was not better with different ratios of EPDM and reclaimed natural rubber. But mechanical properties and particle dispersion of vulcanizates were better than others when the ratio of EPDM and reclaimed natural rubber was 70/30.
