研究了硫化体系及增塑剂种类对乙烯-丙烯酸酯共聚物（AEM）/乙烯与丙烯酸甲酯的共聚物（EMA）共混胶的硫化特性、物理性能、热空气老化性能和热油老化性能的影响。结果表明，随着硫化剂过氧化二异丙苯（DCP）用量的增大，硫化胶的交联密度逐渐增大，硫化速度逐渐变快，100%定伸应力逐渐增大，拉断伸长率逐渐减小，耐油性逐渐变好。在DCP用量为3.0~3.5份时，硫化胶的拉伸强度最大；在DCP用量为2.0~3.0份时，硫化胶的耐热氧老化性最好。随着助硫化剂异氰尿酸三烯丙酯（TAIC）用量的增大，硫化胶的交联密度逐渐增大；混炼胶的硫化速度先变慢后变快，且在TAIC用量为2.0份时，硫化速率最慢；硫化胶的拉伸强度和100%定伸应力逐渐增大，拉断伸长率逐渐减小，撕裂强度逐渐减小；硫化胶的耐热氧老化性逐渐变好。四种增塑剂对AEM/EMA共混胶的增塑效果由好到坏的顺序依次为：邻苯二甲酸二辛酯（DOP）、液体丁腈橡胶（LNBR）、偏苯三酸三辛酯（TOTM）、己二酸二（丁氧基乙氧基乙）酯（TP95）。

The influence of curing systems and kinds of plasticizer on the curing characteristics, physic-mechanical properties, hot air aging properties and hot oil aging properties of AEM/EMA blends were investigated. The results show that, with the increasing of the amount of DCP, the crosslinking density of vulcanizate increases, curing rate gets faster gradually, tensile strength of vulcanizate reaches the top when the amount of DCP was 3.0~3.5phr; the modulus at 100% increases and the elongation at break decreases gradually, the heat oxygen aging resistance of vulcanizate is the best when the amount of DCP is 2.0~3.0phr; the oil resistance of vulcanizate gets better gradually. With the increasing of the amount of TAIC, the crosslinking density of vulcanizate increases, curing rate ifrst becomes slow and then fast, and reaches slowest when the amount of TAIC was 2.0phr, tensile strength and modulus at 100% increases gradually, tear strength decreases, the heat oxygen aging resistance of vulcanizate changes for the better.The plasticization effect of the four kinds of plasticizer on AEM/EMA blends from good to bad is:DOP, LNBR, TOTM, TP95.
