| 中文摘要: |
| 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。 |
| 英文摘要: |
| 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. |
