摘要
研究过氧化物/硫黄复合硫化体系对氢化丁腈橡胶(HNBR)性能的影响。结果表明:随着硫化剂DCP用量的增大,胶料的焦烧时间缩短,硫化速度加快,硫化胶的100%定伸应力增大,压缩永久变形减小,耐热老化性能提高;随着硫黄用量的增大,胶料的硫化速度加快,硫化胶的粘合性能提高;促进剂CZ用量对HNBR胶料性能的影响不大;当硫化剂DCP/硫黄/促进剂CZ用量比为7/0.5/1时,HNBR胶料的综合性能最佳。
The effects of peroxide/sulfur curing systems on the properties of HNBR were investi- gated. The results showed that,as the addition level of curing agent DCP increased,the scorch time of compound was reduced,the curing rate increased, the modulus at 100~ elongation of vulcanizate in- creased, the compression set decreased, and the thermal aging property was improved. As the addition level of sulfur increased,the curing rate of compound increased,and the adhesion improved. The addi- tion level of accelerator CZ had little effect on the properties of HNBR compound. When the blending ratio of curing agent DCP/sulfur/accelerator CZ was compound were the best. 7/0. 5/1 ,the comprehensive properties of HNBR
