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. |
