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.
