摘要
采用4～5份过氧化二异丙苯作主硫化剂,2份2,5-二甲基-2,5-二叔丁基过氧化己烷作助硫化剂,40份沉淀法白炭黑作增强剂,11～15份氢氧化铁作耐热添加剂,可制备耐热温度为300℃的硅橡胶。实验结果表明,试样各项物理机械性能均达到标准要求。
The influence of curing agent, reinforcing fillers and anti-heat agent on the heat resistance of silicon rubber was studied. The results showed that MVC vulcanizate could be used at the elevated temperature up to 300 ℃ by using DCP as main curing agent , DBPMH as secondary curing agent, iron hydroxide as anti-heat agent and silica as filler.
