| 摘 要： | 研究高低温循环作用下三元乙丙橡胶(EPDM)胶料的压缩永久变形及回弹值,考察了EPDM乙烯含量、胶料含胶率和交联程度的影响,并与常温、高温和低温条件下结果进行对比。结果表明:高低温循环作用对EPDM胶料压缩永久变形及回弹值的影响比单纯高温老化的影响大;EPDM乙烯含量、胶料含胶率及交联程度对EPDM胶料在高低温循环作用下压缩永久变形及回弹值的影响很大,其中胶料含胶率的影响最大,其次是EPDM乙烯含量,最后是胶料交联程度。

| Abstract: | The compression set and resilience of ethylene propylene terpolymer(EPDM)compound under cyclic high and low temperature aging were studied and compared with those under normal temperature,high temperature and low temperature conditions.The effects of ethylene content of EPDM,rubber content and crosslinking degree of the compound were investigated.The results showed that,the effect of cyclic high and low temperature aging on the compression set and resilience of the compound was greater than that of high temperature aging.The ethylene content of EPDM,rubber content and crosslinking degree had significant influence on the compression set and resilience of EPDM compound under cyclic high and low temperature aging.The rubber content was the most important influence factor,followed by the ethylene content of EPDM,and finally crosslinking degree. |
