摘　　要：研究了石蜡油对过氧化物硫化及硫黄硫化EPDM交联密度的影响。采用无转子硫化仪MDR测试,结果表明,两种硫化体系得到的硫化胶交联密度随着石蜡油用量的增加而减小,过氧化物硫化胶交联密度下降程度较大,交联效率随着石蜡油用量的增加而减小。The effects of paraffin oil on crosslink density of EPDM vulcanized by peroxide and sulfur respectively were studied.The results showed that crosslink densities decreased with the content of paraffinic oil by Moving Die Rheometer（MDR）,but the decline degree of crosslink density of EPDM cured by peroxide was much while peroxide curing efficiency declined with paraffinic oil.
