中文摘要:
      以液体聚异戊二烯橡胶（LIR）为反应型增塑剂，研究LIR对NR/BR混炼胶性能、硫化胶物理性能和耐热空气老化性能的影响，并与添加芳烃油的NR/BR并用胶进行对比。结果表明，LIR对NR/BR混炼胶有增塑作用，但增塑效果不如芳烃油；添加LIR的NR/BR硫化胶的物理性能总体上优于相应的芳烃油硫化胶，耐热空气老化性能也较好；LIR在硫化过程中可与NR和BR发生共交联。
英文摘要:
      The effect of liquid isoprene rubber(LIR) on properties of NR/BR compound，physical properties and thermal air aging property of its vulcanizate was investigated and compared to that of aromatic oil.The results showed that the plasticating effect of LIR on NR/BR blend was lower than that of aromatic oil；the comprehensive physical properties and thermal air aging property of NR/BR vulcanizate with LIR were better than those with aromatic oil；and LIR was co-crosslinked with NR and BR during vulcanization.
