摘　　要：本文对比分析了不同用量的双三乙氧基甲硅烷基丙基四硫化物(Si69)和双叔丁基过氧化二异丙基苯(BIBP)对EPDM硫化特性、力学性能与电绝缘性的影响。结果表明:随着Si69和BIBP含量的增加,硫化速度增大,工艺正硫化时间缩短,最大扭矩增大,胶料的交联密度提高,力学性能有所改善;其中随着Si69含量的增加,胶料的电绝缘性降低;而随着BIBP含量的增加,胶料的电绝缘性逐渐提高。The effect of different contents of bis-triethoxysilylpropyl tetrasulfide(Si69)and bis(tert-butylperoxy diisopropyl)benzene(BIBP)on vulcanization characteristics,mechanical properties,and electrical insulation property of EPDM were compared and analyzed.The results show that with the increase of Si69 and BIBP content,the curing speed increases,the process positive curing time decreases,the maximum torque increases,the crosslinking density of the rubber increases and the mechanical properties are improved.With the increase of Si69 content,the electrical insulation property of the rubber decreases;with the increase of BIBP content,the electrical insulation property of the rubber increases gradually.
