摘　　要：研究白炭黑用量、炭黑粒径和填充剂种类对氯化聚乙烯橡胶(CM)发泡材料物理性能和泡孔结构的影响。结果表明:当白炭黑用量为30份时,CM发泡材料的泡孔尺寸较小且分布均匀;填充炭黑N550的发泡材料具有较大的拉伸强度和较小的压缩永久变形,泡孔小且密;添加轻质碳酸钙的发泡材料泡孔小,泡孔壁薄,填充高岭土的发泡材料泡孔大且均匀。The effects of the addition level of silica,particle size of carbon black and use of other fillers on the physical properties and pore st size of CM foam was smaller and the pores was 30 phr. Filled with carbon lack N550, t pression set was lower,while the pores had ructure of CM foam were investigated. With silica, the wet e uniformly distributed when the addition level of tensile strength of CM foam was higher and the pore silica COrn- small size and were distributed densely. With light calcium carbonate, the pore size was also small and pore wall was thin. With Kaoline, the pores of CM foam had big size and were well distributed.
