对试样进行了硬度、拉伸强度、断裂伸长率、热老化等性能试验；对老化后的试样表面进行了SEM表征。

Hardness, tensile strength, breaking elongation ratio and aging property of samples were tested and surface of sample after aging was represented by SEM.

添加黑液干粉的复合材料，在热氧老化后拉伸强度和邵尔A型硬度增加，断裂伸长率稍有下降。

In general, the tensile strength and Shore A hardness of PVC/CPE/black liquor powder composites were increased while the elongation at break was slightly decreased after thermo-oxidative aged.
