| 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。

| Abstract: | The effect of acrylonitrile content of nitrile rubber（NBR） on the properties of NBR/polyvinylchloride（PVC） foamed materials was investigated. The results showed that at the same accelerator amountused，the vulcanization and foaming compatibility of NBR/PVC compounds with different acrylonitrilecontents in NBR and the physical properties of the foaming materials varied greatly. By adjusting the amountof the accelerator，the vulcanization and foaming compatibility of NBR/PVC compounds were improved toprepare foaming materials with low apparent density，low vacuum water absorption，low thermal conductivityand good compression resilience. |
