摘　　要：采用机械共混法研究了三元乙丙橡胶/甲基乙烯基硅橡胶(EPDM/MVQ)并用的配方和工艺对共混胶物理机械性能和热空气老化性能的影响。从并用MVQ改性来提高EPDM耐热性方面考虑,单因素分析结果表明:以过氧化物DCP硫化为主,加少量硫磺或N,N-间苯撑双马来酰亚胺(HVA-2)有助于二者的共硫化;填充高耐磨炭黑同时并用部分快压出炉炭黑综合性能较好;防老剂RD和MB能产生较好的协同效应;通过分别制备二者的母炼胶进行混炼,并加入少量硅烷偶联剂改善了两者的相容性。The mechanical blends of ethylene propylene diene monomer（EPDM） and methyl vinyl silicone rubber （MVQ）, including the effect of formula and blending process on mechanical properties and heat aging properties of the blends were studied. From the consideration of the heat-resistance of this blends, single-factor analysis showed that： With DCP as the main curing agent, adding a small amount of sulfur or N, N-inter-phenylene bismaleimide （HVA-2） contribute to co-vulcanization; The material filled with HAF and some HEF has good performances; RD and MB can generate good synergy; Masterbatch blending and adding some silane coupling agents can improve their compatibility.
