中文摘要:
      讨论NBR丙烯腈含量对NR/BR/NBR并用胶加工性能、物理性能和动态力学性能的影响。试验结果表明,用少量(5份)丙烯腈质量分数较大(0.35)的NBR等量替代NR/BR并用体系中的NR,并用胶0 ℃时的tanδ值增大,耐热老化性能提高,65 ℃时的tanδ值和物理性能变化较小,加工性能稍有降低。NR、BR和少量丙烯腈含量较大的NBR并用,可以获得抗湿滑性能较好、滚动阻力较小且性价比较理想的胎面胶。
英文摘要:
      The effect of the acrylnitrile content in NBR on the processibility,physical properties and dynamic properties of NR/BR/NBR blend was investigated.The results showed that the tanδ at 0 ℃ of the blend increased,the thermal aging property improved,the tanδ at 65 ℃ and the physical properties changed little,and the processibility decreased somewhat by using 5 phr of NBR with higher content (0.35) of acrylnitrile instead of the equal amount of NR in NR/BR blend,thus a tread stock with better wet traction,lower rolling resistance and reasonable performance/cost ratio was obtained.
