%X 通过硅氢加成法合成八（三甲氧基硅乙基）笼形倍半硅氧烷（OPS），将其作为耐热助剂制备OPS/乙烯基硅橡胶复合材料，研究OPS用量对硅橡胶复合材料性能的影响。结果表明：与乙烯基硅橡胶相比，OPS/乙烯基硅橡胶复合材料的初始分解温度明显提高，耐热性能改善；当OPS用量为9份时，复合材料的耐热老化性能较优，拉伸强度和剪切强度较高。;The octa（trimethoxysilylethyl）cage silsesquioxane（OPS）was synthesized by hydrosilation and it was used as heat-resistant additive to prepare OPS/vinyl silicone rubber composites.The effect of OPS amount on the properties of the composites was investigated.The results showed that，the initial decomposition temperature and heat resistance of OPS/vinyl silicone rubber composites were obviously improved.When the OPS amount was 9 phr，the heat resistance of the composites was better than that of vinyl silicone rubber，and the tensile strength and shear strength were higher
