摘　　要：以溴化丁基橡胶(BIIR)等量替代天然橡胶(NR)和顺丁橡胶(BR),分别制备NR/BIIR和NR/BR/BIIR并用胶,研究并用胶的物理性能、耐热空气老化性能和动态力学性能的变化。结果表明:与NR胶料和NR/BR并用胶分别相比,NR/BIIR和NR/BR/BIIR并用胶的物理性能略有下降,耐热空气老化性能大幅度提升,抗湿滑性能提高、滚动阻力变化不大;当BIIR用量分别为10和15份时,NR/BIIR和NR/BR/BIIR并用胶的耐热空气老化性能较好。NR/BIIR and NR/BR/BIIR blends were prepared and the physical properties,heat air aging resistance and dynamic mechanical properties of the blends were investigated.The results showed that,compared with the compound without BIIR,the physical properties of therespective blend with BIIR decreased slightly,the hot air aging resistance increased significantly,the wet-skid resistance was improved,and the rolling resistance changed little.When the BIIR amounts in the NR/BIIR and NR/BR/BIIR blends were 10 and 15 phr,respectively,the heat air aging resistance of the blends were excellent.
