硫化体系对二元共聚氯醚橡胶性能的影响

探讨促进剂NA-22硫化体系和三嗪硫醇（包括硫化剂AF和TCY）硫化体系对二元共聚氯醚橡胶（CHC）性能的影响。结果表明，促进剂NA-22/二盐基亚磷酸铅硫化体系的硫化胶性能较好，但促进剂NA-22有致癌作用，二盐基亚磷酸铅有毒且污染模具；三嗪硫醇/氧化镁/促进剂DM或防焦剂CTP硫化体系的硫化胶性能稍差，但制品生产和应用环保性较好。硫化剂AF和TCY是CHC较理想的环保型硫化剂。;The effects of the accelerator NA-22 curing system and triazine-mercaptan(including curatives AF and TCY) curing system on the properties of epichlorohydrin binary copolymer(CHC) were investigated.The results showed that the accelerator NA-22/dibasic lead phosphite curing system gave the vulcanizate better physical properties，but NA-22 was cancerogenic and dibasic lead phosphite was toxic and pollutant to mold；triazine-mercaptan/magnesium oxide/accelerator DM or scorch retardant CTP curing system was environment-friendly，although it gave the vulcanizate somewhat poorer properties；and the curatives AF and TCY were ideal environment-friendly curatives for CHC
