摘　　要：研究丁腈橡胶(NBR)丙烯腈含量对NBR/聚氯乙烯(PVC)发泡材料性能的影响。结果表明:在相同促进剂用量下,不同丙烯腈含量NBR/PVC混炼胶的硫化与发泡匹配性和发泡材料的物理性能差别大;通过调节促进剂用量,可改善NBR/PVC混炼胶的硫化与发泡匹配性,以制备出表观密度、真空吸水率、热导率小以及压缩回弹性好的发泡材料。The effect of acrylonitrile content of nitrile rubber(NBR)on the properties of NBR/polyvinyl chloride(PVC)foamed materials was investigated.The results showed that at the same accelerator amount used,the vulcanization and foaming compatibility of NBR/PVC compounds with different acrylonitrile contents in NBR and the physical properties of the foaming materials varied greatly.By adjusting the amount of the accelerator,the vulcanization and foaming compatibility of NBR/PVC compounds were improved to prepare foaming materials with low apparent density,low vacuum water absorption,low thermal conductivity and good compression resilience.
