| 中文摘要: |
| 研究5种抗氧剂对苯乙烯-丁二烯-苯乙烯嵌段共聚物（SBS）耐老化性能的影响。结果表明：随着老化时间的延长，加入不同抗氧剂的SBS的黄色指数变化规律不同，硬度呈下降趋势，氧化诱导时间缩短；其中加入抗氧剂565/705T和B7081L的SBS的耐黄变性能较好，氧化诱导时间保持率较高，耐老化性能明显提高。 |
| 英文摘要: |
| The effect of five antioxidants on the aging property of styrene-butadiene-styrene block copolymer（SBS） was studied.The results showed that with the aging time prolonged，the varying tendency yellowness index of SBS with different antioxidants were different，the hardness decreased，and oxidation induction time tended to be shortened.Among them，the yellowing resistance of SBS with antioxidant 565/705T and B7081L were better，the retention rate of oxidation induction time were higher and the aging property were significantly improved. |
