摘　　要：对比分析了纯放热性发泡剂AC与吸 -放热复合发泡剂DDL 10 5的分解与发泡特性。详细比较了以这两类发泡剂在相同配方和加工条件下样品的发泡倍率、泡孔结构差别以及对温度和时间的依赖关系。The decomposition and foaming characteristic of the exothermic foaming agent AC and endo exothermic compound foaming agent DDL 105 used for PVC leather were analyzed. The foaming capacity,cell structure,and dependence on temperature and time of the two kinds of the agents were compared in the same compounding recipe and processing conditions.
