中文摘要:
      研究硫化体系对氢化丁腈橡胶（HNBR）/氯丁橡胶（CR）（并用比70/30）并用胶硫化特性、物理性能和耐热老化性能的影响。结果表明：采用硫化剂DCP/助硫化剂TAIC硫化体系时，HNBR/CR并用胶的焦烧时间较长，拉断伸长率较大，拉断永久变形较小，耐热老化性能较好；当硫化剂DCP用量为5份、助硫化剂TAIC用量为3份时，并用胶的硫化速率较大，加工安全性、耐油性能、综合物理性能和耐热老化性能较好。
英文摘要:
      The influence of curing systems on the curing behavior，physical properties and thermal aging property of HNBR/CR blend （blend ratio 70/30） was investigated.The results showed that，when the curing system of main curing agent DCP and co-curing agent TAIC was used，the scorch time of HNBR/CR blend was longer，elongation at break was higher，tensile set at break was lower，and thermal aging property was better.When the addition levels of DCP and TAIC were 5 and 3 phr respectively，the curing rate of HNBR/CR blend washigh，and processing safety，oilresistance，comprehensive physical properties and thermal aging property were good.
