中文摘要:
      采用双硫化体系，制备了NR/NBR/氯醚橡胶(CO)三元共混硫化胶，并对硫化胶的性能进行了测试。实验结果表明：采用促进剂NA-22/硫黄/氧化锌硫化体系可实现共混物的同步硫化；CO对NR的性能有较大的影响，少量的CO可有效地提高NR的耐老化、耐介质和气密性，但共混物的耐水性能比NR略有下降。
英文摘要:
      NR/NBR/CO vulcanizates were prepared by using double curing system，and their properties were investigated.The results showed that the blends could be simutaneously vulcanized with accelerator NA-22/sulfur/ZnO curing system；CO had a significant influence on the properties of NR；the aging properties，the chemical media resistance and the air-tighness improved significantly，but the water resistance decreased slightly when NR was blended with a small proportion of CO.
