摘　　要：采用模压法进行发泡,研究氯化聚乙烯橡胶(CM)与聚氯乙烯(PVC)的共混比和发泡剂AC用量对发泡体的性能和泡孔结构的影响。结果表明:随着CM用量的增大,CM/PVC发泡材料的发泡密度逐渐减小,泡孔体积和发泡倍率逐渐增大,当CM/PVC共混比为50/50时,发泡材料具有较好的综合性能;随着发泡剂AC用量的增大,发泡材料的发泡密度减小,拉伸强度和撕裂强度逐渐减小。The microcellular foam of CM/PVC blend was prepared by molding method.The effect of blending ratio and addition level of foaming agent on the properties and microcellular structure of CM/PVC microcellular foam was investigated.The results showed that,as the addition level of CM increased,the density of CM/PVC microcellular foam decreased,and the volume of cell and foaming ratio increased.When the blending ratio of CM/PVC was 50/50,the foam material possessed better properties.As the addition level of foaming agent AC increased,the foam density,tensile strength and tear strength of the foam material decreased.
