硫化促进剂对氯丁橡胶性能的影响

摘要

Influence of different vulcanization accelerator and curing temperature on neoprene vulcanization and mechanical behavior was investigated. The results indicate that: curing time and scorch time of CR at 180 ℃ are shorter than that at 170 ℃ in the most of curing system. The shortest curing time and better mechanical property can be obtained when ZnO(5),MgO(4) , NA-22(1), TMTD(0.5)and silica (40) treated with silane coupling agent KH550 are added.%讨论了不同硫化促进剂和硫化温度对氯丁橡胶硫化和力学性能的影响。结果表明：多数胶料在180℃硫化比在170℃硫化的正硫化时间短，焦烧时间也短。在加入 ZnO 5份、MgO 4份，NA-221份、TMTD 0.5份，KH550活化的白炭黑40份时，胶料获得最短的硫化时间，且该体系也能使胶料获得较好的力学性能。
