中文摘要:
      讨论了硫化反应活化能与并用胶性能之间的关系。根据阿累尼乌斯公式，求出CPE/NBR并用胶硫化反应活化能。结果发现，当该活化能与CPE或NBR单一胶相在同一硫化体系下硫化的活化能十分接近时，并用胶的物性可以达到两种胶料物性的加和水平。硫脲-硫黄-超速促进剂硫化体系适用于CPE/NBR并用胶，当并用比为80：20时，硫化胶具有良好的耐油性和强伸性能。
英文摘要:
      The relationship between the activation energy of vulcanization and the properties of blend was discussed. The activation energy of vulcanization of CPE/NBR blend was obtained using Arrhenius formula. The results showed that the physical properties of the blend were com-parable to the compromised properties of the two rubbers when the activation energy of the blend was close to that of CPE or NBR with the same curing system. The thiourea/sulfur/super acce-lerator system was suitable for CPE/NBR blend. The vulcanizate with good oil resistance and ten-sile properties was obtained when the blending ratio of CPE/NBR was 80 : 20.
