摘　　要：对比研究了新型硫黄给予体烷基苯酚二硫化物CV-50与DTDM-80、CLD-80等硫黄给予体硫化剂在EPDM配方中的应用特性。结果表明:CV-50在高温硫化时不会生成致癌性的亚硝胺及亚硝胺类物质,相较于常用的硫载体硫化剂,其气味最轻;CV-50所对应胶料的力学性能、耐热氧老化性能、压缩永久变形等基本与之相当,但其环保且价格优惠,因而烷基苯酚二硫化物CV-50是DTDM-80、CLD-80等的理想环保替代物。The Properties of alkylphenol disulfide CV-50,DTDM-80 and CLD-80 in EPDM formulation were compared and studied.The results showed that CV-50 did not produce carcinogenic nitrosamines and nitrosamines substance during high-temperature vulcanization,and its odor was the lightest compared to commonly used sulfur donor vulcanizing agents;The mechanical properties,heat and oxygen aging resistance properties,and compression set of the corresponding compound of CV-50 were basically the same as those of the compound of DTDM-80,but CV-50 was environmentally friendly and cost effective.Therefore,CV-50 was an ideal environmentally friendly alternatives to DTDM-80,CLD-80,etc.
