摘要
研究了不同防老体系对SBS老化性能的影响。考察了不同老化体系下SBS拉伸强度、断裂伸长率、拉伸永久形变和硬度随老化时间的变化情况。研究结果表明:新型辅助型防老剂ZH的加入对于防止SBS老化后拉伸强度的下降作用不大,但对于防止SBS老化后断裂伸长率的下降却有一定的贡献。
The effect of different antioxidants on thermal aging properties of SBS was studied. The change of tensile strength, elongation at break, tensile permanent set and hardness of SBS with aging time on different antioxidants was investigated. The results showed that adding new assisted antioxidant ZH produced little effect for preventing the tensile strength decreased of SBS after aging, but was useful for preventing the elongation at break decreased of SBS after aging.
