| 中文摘要: |
| 对丁腈橡胶－40(NIBR-40）与三元共聚型氯醚橡胶（CHC）进行了并用研究，发现二者之间的相容性良好。 NBR-40/CHC并用比为80/20时，胶料的综合物理性能较好；为 70/30时·胶料耐40#机油的性能最好：耐四氯化碳溶剂的性能随并用比的减小（CHC用量增加）而提高。 胶料硫化体系以过氧化物硫化体系[过氧化二异丙苯（DCP）/硫黄/四氧化三铅/促进剂NA-22］最佳，补强剂选用中超耐磨炭黑。 |
| 英文摘要: |
| A study on NBR-40/CHC blend was made and the good compatibility between them was found，The compound showed good comprehensive physical properties when the blending ratio of NBR/CHC was 80/20;the compound showed excellent engine oil resistance when the blending ratio was 70/30；the carbon tetrachloride resistance improved with the increase of the CHC level in the blend，The optimum curing system was peroxide (DCP)/sulfur/lead tetraoxide/accelerator NA-22 system and MSAF was preferable reinforcing agent. |
