| 摘 要： | 采用动态热机械分析仪RSA3代替硫化仪来测试硅橡胶的硫化特性,使用多乙烯基硅油(C胶)作为集中交联剂,分别选择DCP、BPO及两者并用硫化体系作为集中交联硅橡胶体系的硫化剂,研究了不同硫化剂对集中交联硅橡胶硫化曲线的影响,分析了硅橡胶在不同硫化体系下发生交联反应的差异,讨论了硅橡胶在不同温度下的硫化反应速率.研究结果表明:对于集中交联体系的硅橡胶,BPO硫化效果不好,DCP能有效硫化,并用硫化体系的硫化效果最好,且可以在不影响其硫化反应速率的同时使硅橡胶实现高低温分段硫化.

| Abstract: | The curing characteristics of unvulcanized filled silicone rubber were investigated by a Dynamic Mechanical Thermal Analyzer(DMTA) called RSA3 instead of curemeters.The influence of curing agent type on the curing characteristics of silicone rubber when choosing polyvinylsilicone oil,namely C gum,as concentrative crosslinker were studied.And the differences of crosslink reactions of rubber with three different curing agents were also discussed.The results show that benzoyl peroxide(BPO) can't well cure sili... |
