中文摘要:
      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。
英文摘要:
      The effects of polymer grade,curing system,softener,antioxidant and test temperature on the compression set of ethylene-propylene terpolymer rubber(EPDM)were studied.The data showed that the compression set was lower for ESPRENE 553 cured with dicumyl peroxide(DCP) and would be further improved by adding 3 parts of 2-mercapto benzimidazole(MB).The compression set of EPDM would increase by the addition of antioxidant RD,antioxidant 2246 and No.30 engine oil.
