采用模压法制备的顺丁橡胶(BR)/丁苯橡胶(SBR)/天然橡胶(NR)并用胶,分别填充3种分子量的环烷油和石蜡油,考察几种橡胶油对并用胶硫化性能及力学性能的影响。结果表明,充油的胶料较未充油的胶料硫化性能均有一定的改变,其中最大最小扭矩、扭矩差、最大硫化速率、正硫化时间、最大硫化时间,均有不同程度的减小或缩短,而焦烧时间均有所延长;对比相同分子量的环烷油和石蜡油,环烷油对并用胶硫化性能的积极影响大于石蜡油。充油后的硫化并用胶的力学性能均有所下降(除冲击回弹率有所上升);对比相同分子量的两类油,填充环烷油对硫化并用胶力学性能的改善作用优于石蜡油。
(BR) / styrene butadiene rubber (SBR) / natural rubber (NR) prepared by molding method were respectively filled with three kinds of naphthenic oil and paraffin oil with molecular weight. The effects of several kinds of rubber oil on the vulcanizate properties And mechanical properties. The results show that the oil-filled rubber has some changes compared with the rubber without oil-filled. The maximum and minimum torque, torque difference, maximum vulcanization rate, positive vulcanization time and maximum vulcanization time are all decreased to some extent Or shortened, while the scorch time has been extended; compared with the same molecular weight of naphthenic oil and paraffin oil, naphthenic oil and co-curing of the positive effect is greater than the paraffin oil. Compared with the same molecular weight of two types of oil, filled naphthenic oil is better than paraffin oil in improving the mechanical properties of vulcanization and adhesive. .
