摘要
考察了硅橡胶／橡胶型乙烯醋酸乙烯酯共聚物（ＥＶＭ）用量比、过氧化物品种及其用量、相容剂等因素对硅橡胶／ＥＶＭ共混物物理性能的影响。实验结果表明，硅橡胶／ＥＶＭ用量比大于１时，共混物强度性能主要受硅橡胶的影响；硫化剂选用ＤＣＰ较为合适；共混物的性能低于两种单一胶种性能的加和值，两胶种相容性较差；以乙烯基三乙氧基硅烷接枝ＥＶＭ作为相容剂，对该共混体系两相间的相容性有一定的改善。
The effect of the ratio of silicone rubber( Q ) and EVM,the type and level of curative and compatibilizer on the properties of silicone/EVM blend was studied.The results showed that the tensile strength of the blend was mainly influenced by silicone rubber when the ratio of silicone rubber/EVM was greater than 1;DCP was the suitable curative;the properties of the blend was lower than either single rubber because of the poor compatibility of two rubbers;the compatibility of the blend improved when the EVM grafted with vinyltriethoxysilane was used as the compatibilizer.
