顺丁橡胶/集成橡胶并用胶的结构及性能

考察了顺丁橡胶（BR）与集成橡胶（SIBR）并用质量比对BR/SIBR并用胶的相态结构、热性能、硫化特性、动态力学性能、物理机械性能、耐切割性能、耐磨性能和压缩疲劳生热的影响.结果表明,当BR/SIBR为20/80,30/70,40/60时,并用胶的相态结构均匀;BR/SIBR为50/50时,并用胶呈明显的相分离结构;随着BR用量的增加,并用胶的玻璃化转变温度（Ts）降低,当BR/SIBR为50/50时,BR/SIBR并用胶出现2个Tg,相容性最差;随着BR用量的增加,并用胶的焦烧时间先小幅延长后逐渐缩短,正硫化时间逐渐缩短,损耗因子（tanδ）峰向低温方向移动,与SIBR硫化胶相比,并用胶的...

Summary:考察了顺丁橡胶（BR）与集成橡胶（SIBR）并用质量比对BR/SIBR并用胶的相态结构、热性能、硫化特性、动态力学性能、物理机械性能、耐切割性能、耐磨性能和压缩疲劳生热的影响.结果表明,当BR/SIBR为20/80,30/70,40/60时,并用胶的相态结构均匀;BR/SIBR为50/50时,并用胶呈明显的相分离结构;随着BR用量的增加,并用胶的玻璃化转变温度（Ts）降低,当BR/SIBR为50/50时,BR/SIBR并用胶出现2个Tg,相容性最差;随着BR用量的增加,并用胶的焦烧时间先小幅延长后逐渐缩短,正硫化时间逐渐缩短,损耗因子（tanδ）峰向低温方向移动,与SIBR硫化胶相比,并用胶的tan δ峰宽均变窄,定伸应力、压缩疲劳生热变化不大,但拉伸强度、撕裂强度和耐磨性能有所降低,耐切割性能下降较大.

Effect of mass ratios of cis-1,4-poly- butadiene rubber（BR） to integrated rubber （SIBR） on morphological structure, thermal properties, cu- ring characteristics, dynamical mechanical proper- ties, mechanical properties, cutting resistance, wear resistance and heat build-up of the BR/SIBR blends were investigated. The results showed that the mor- phological structures of BR/SIBR blends were uni- form at mass ratios of BR/SIBR of 20/80, 30/70 and 40/60, but the blends exhibited evident phase separation at mass ratio of 50/50. With increasing BR, the glass transition tempe
