摘　　要：研究炭黑品种和用量对乙烯丙烯酸酯橡胶(AEM)硫化特性、物理性能、耐热老化性能和耐油性能的影响。结果表明:随着炭黑粒径的增大,AEM胶料的焦烧时间延长,物理性能和耐热老化性能降低,耐油性能提高,炭黑N660/AEM胶料的综合性能最好;随着炭黑N660用量的增大,AEM胶料的焦烧时间缩短,物理性能先升高后降低,耐油性能提高,耐热老化性能降低,炭黑N660用量为60份时AEM胶料的综合性能较好;炭黑N550/N774并用比为40/40时,AEM胶料的综合性能较好。The effects of types and addition level of carbon black on the curing behavior, physical properties, heat aging resistance and oil resistance of AEM compound were investigated. The results showed that,as particle size of carbon black increased, the scorch time of AEM compound extended, physical properties and heat aging resistance decreased, and oil resistance was improved. The compre- hensive properties of carbon black N660/AEM compound were the best. As the addition level of car- bon black N660 increased,the scorch time of AEM compound shortened, physical properties were im- proved at first and then deteriorated,oil resistance was improved, and heat aging resistance was de- creased. When the addition level of N660 was 60 phr, the comprehensive properties of carbon black N660/AEM compound were the best. When the blend ratio of carbon black N550/N774 was 40/40, the comprehensive properties of AEM compound were also good.
