【摘要】 利用环氧化天然橡胶(ENR)与天然橡胶(NR)和三元乙丙橡胶(EPDM)均有很好相容性的特点,采用硫化促进剂预混工艺对NR/EPDM并用胶实施共硫化。考察了其对NR/EPDM并用胶的硫化特性、硫化胶的物理机械性能和耐热空气老化性能的影响。结果表明:本工艺确实能改善NR/EPDM的共硫化性能,所得硫化胶物理性能较好且操作简单。更多还原

【Abstract】 The good compatibility of epoxidized nature rubber(ENR)to both nature rubber (NR)and ethylene-propylene-diene terpolymer(EPDM) was used to co-curing NR/EPDM blends through particular process technology which was pre-mixing some sulpher cure systems in ENR before use it to co-crosslinking NR/EPDM blends. The effects of vulcanization properties of compound and physical properties and aging-resistance properties of vulcanizates of NR/EPDM blends which produced by the process technology were studied. The results showed that the problem of bad co-vulcanization of NR/EPDM blends were improved, and the vulcanizates of NR/EPDM blends had excellent physical properties, moreover, the process technology was easy to apply.更多还原
