摘　　要：研究了EPDM/FKM共混比对共混胶性能的影响,研究表明,乙丙橡胶中加入氟橡胶,可以降低共混胶的性能变化率,可以提高共混胶在46#液压油、刹车油中的耐热油性能,可以提高共混胶的耐高温性能,因此可以通过在乙丙橡胶中加入氟橡胶来提高共混胶的耐高温及老化性能。The effect of EPDM/FKM blending ratio on the properties of blended rubber was studied.Studies have shown that the addition of fluororubber to ethylene-propylene rubber can reduce the performance change rate of the blended rubber,can improve the heat-resistant oil performance of the blended rubber in 46^# hydraulic oil and brake oil,and can improve the high-temperature resistance of the blended rubber.Therefore,it is possible to improve the high temperature resistance and aging properties of the blended rubber by adding fluorine rubber to ethylene-propylene rubber.
