摘要
在７０ 份三元乙丙橡胶（ＥＰＤＭ） 与３０ 份三元共聚尼龙（ＰＡ） 的共混体系中掺入１５ 份的氯化聚乙烯，采用过氧化物硫化体系，可作为耐热氧老化的高性能弹性体的基础配方。实验结果表明，与未采用ＰＡ 增强的ＥＰＤＭ 过氧化物硫化胶相比，ＥＰＤＭ／ ＰＡ 共混物的撕裂强度及拉伸强度有大幅度提高，耐热氧老化性能优良，磨耗及动态生热有明显改善。
Elastomer with high mechanical properties and excellent heat and oxygen resistance was prepared in the blending system of EPDM/PA(70/30)by blending with 15 phr of DCP. The results showed that the tear strength,tensile strength,heat and oxygen resistance, abrasion and dynamic heat generation of the blends improved significantly. The micro-morphological structures of these blends were studied in certain degree.
