摘　　要：三元乙丙橡胶(EPDM)为非极性高分子材料,硅橡胶(MVQ)为半无机高分子材料。要获得性能优异的EPDM/MVQ共混胶,提高EPDM和MVQ的相容性是关键。研究了不同种类硅烷偶联剂作为相容剂对EPDM/MVQ共混胶性能的影响,并对偶联剂的并用进行了研究。实验结果表明:加入硅烷偶联剂Si-69或KH-550均能使EPDM/MVQ共混胶的力学性能得到改善;适量的硅烷偶联剂A-172与炭黑反应,使得炭黑成为体系的交联点,因此炭黑在共混体系中分散更均匀,从而使EPDM/MVQ共混胶达到较好的力学性能。The EPDM is polar polymer material, but the MVQ is half-inorganic polymer material. To obtain EPDM/MVQ mixing rubber with excellent performance, the key is that improving the compatibility property of MVQ and EPDM. The paper has studied the influence to the performance of EPDM/MVQ mixing rubber for the using of different kinds of silane coupling agent as the compatibilizer, also the combined use of silane coupling agent was studied. Experimental results show that. the silane coupling agent Si-69 or KH-550 can make EPDM/MVQ mixing rubbet＇s mechanics properties improved. The interaction of the right amount of silane coupling agent A-172 and carbon black makes carbon black become the system＇s crosslinking point, carbon black is more evenly dispersed in blending system, thus EPDM/MVQ blending glue achieves good mechanical properties.
