抗氧劑對SBS老化行為研究 |
| 周立新(巴陵石油化工有限責任公司合成橡膠事業(yè)部; 湖南岳陽(yáng)) |
| 摘 要：研究了SBS添加不同抗氧體系的熱氧老化行為,考察了SBS拉伸強度、扯斷伸長(cháng)率、扯斷永久變形、硬度隨熱氧老化時(shí)間的變化規律,結果標明SBS在熱氧老化過(guò)程中其拉伸強度、扯斷伸長(cháng)率會(huì )出現峰值,隨后呈下降趨勢,而SBS的扯斷永久變形呈上升趨勢,硬度則漸漸下降。選擇抗氧體系對SBS抗熱氧老化性能影響顯著(zhù)。 |

| Effect of Complex Antioxidants on Aging Property of SBS |
| ZHOU Li-xin （Synthetic Rubber Plant Baling Petrochemical Co.; Ltd.; Yueyang 414014; China） |
| 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. |
| Key words：SBS; thermal aging; antioxidant system |
