摘要
研究了不同硫化体系、防老剂及试验温度对４种牌号的三元乙丙橡胶的压缩永久变形的影响。结果表明：采用过氧化物ＤＣＰ硫化体系硫化的三元乙丙橡胶ＥＳＰＲＥＮＥ５５３牌号硫化胶，可获得较低的压缩永久变形，且随试验温度的升高呈现近似线性增大的程度也较小；加入３份防老剂ＭＢ，可进一步降低其压缩永久变形。防老剂ＲＤ、防老剂２２４６及３０号机油均可使三元乙丙橡胶压缩永久变形增大。
The effects of polymer grade, curing system, softener, antioxidant and testtemperature on the compression set of ethylene-propylene terpolymer rubber (EPDM) werestudied. The data showed that the compression set was lower for ESPRENE 553 cured withdicumyl peroxide (DCP) and would be further improved by adding 3 parts of 2-mercaptobenzimidazole (MB). The compression set of EPDM would increase by the addition ofantioxidant RD,antioxidant 2246 and No. 30 engine oil.
