研究了促进剂/硫磺和交联助剂/过氧化物用量配比对丁苯橡胶(SBR)硫化胶硫化特性、力学性能和耐热老化性能的影响。将促进剂/硫磺用量配比按照三种硫磺硫化体系进行对比研究,这三种硫化体系分别是普通硫化体系、半有效硫化体系(SEV)和有效硫化体系(EV)。甲基丙烯酸锌(ZDMA)作为过氧化物的交联助剂,在提高过氧化物反应性能的同时,还能够提供离子键,ZDMA提供的离子键在两个聚合物大分子之间架桥,起到交联作用。ZDMA/过氧化物用量配比系数为变量,比值范围从 The effects of accelerator / sulfur and cross-linking aid / peroxide ratio on the vulcanization properties, mechanical properties and heat aging resistance of SBR vulcanizates were investigated. The ratio of accelerator to sulfur was compared according to three kinds of sulfur vulcanization systems, which were general vulcanization system, semi-effective vulcanization system (SEV) and effective vulcanization system (EV) respectively. ZDMA, as a cross-linking aid for peroxide, can provide ionic bond while improving peroxide reactivity. The ionic bond provided by ZDMA bridges between two polymer macromolecules, Play cross-linking effect. ZDMA / peroxide dosage ratio coefficient for the variable ratio range from
