中文摘要:
      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。
英文摘要:
      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.
