Curing System and Process of Silicone Rubber With Concentrative Crosslinker
摘要
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 silicone rubber with C gum. While the di-cumyl peroxide (DCP) , one vinyl-specific curing agent, can well cure silicone rubber with C gum. The best cure effect in the presence of concentrative crosslinking of silicone rubber of this research is a combination of DCP and BPO. The silicone rubber cured with the combination of BPO and DCP have high modulus, and the rubber can be cured by two cure stages of low and high cure temperature without cure reactions rate decreasing.关键词
