丙烯酸酯橡胶/乙烯丙烯酸酯橡胶并用胶性能的研究

制备丙烯酸酯橡胶(ACM)/乙烯丙烯酸酯橡胶(AEM)并用胶，并对其性能进行研究。结果表明：ACM与AEM并用能够实现共硫化；与ACM相比，ACM/AEM并用胶的拉伸强度增大，耐热空气老化性能和耐低温性能得到改善，耐油性能有所下降。当ACM/AEM并用比为60/40、炭黑N550和N774用量分别为40份、1#硫化剂用量为1.5份时，ACM/AEM并用胶的物理性能最佳。;The blend of Acrylate rubber (ACM)/ethylene acrylate rubber (AEM) was prepared，and its properties were investigated.The results showed that，ACM and AEM could be co-vulcanized.Compared with ACM，the tensile strength of ACM/AEM blend was increased，the hot air aging resistance and low temperature resistance were improved，but the oil resistance was slightly decreased.As the ACM/AEM blend ratio was 60/40，the addition levels of carbon black N550 and N774 were 40 phr each，and the addition level of 1^# vulcanizing agent was 1.5 phr，the blend showed optimum comprehensive properties
