| 摘 要： | 研究了SBS添加不同抗氧体系的热氧老化行为,考察了SBS拉伸强度、扯断伸长率、扯断永久变形、硬度随热氧老化时间的变化规律,结果标明SBS在热氧老化过程中其拉伸强度、扯断伸长率会出现峰值,随后呈下降趋势,而SBS的扯断永久变形呈上升趋势,硬度则渐渐下降。选择抗氧体系对SBS抗热氧老化性能影响显著。

| Abstract: | The effect of different antioxidants on thermal aging property of SBS was studied in this article. Change of tensile strength,elongation at break, permanent set and hardness of SBS with the aging time were investigated. The results showed that the tensile strength and elongation at break would reach a peak,and then began to fall,but the permanent set began to rise,and the hardness fell down gradually. The choice of antioxidant had a remarkable effect on the aging property of SBS. |
