摘要
对丁腈橡胶－４０（ＮＢＲ－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。
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.
