| 中文摘要: |
| 研究防老剂A7750在轮胎胎侧胶中的应用。结果表明：与添加防老剂4020的胶料相比，添加防老剂4030的胶料具有更好的耐静态臭氧老化性能和耐迁移变色性能；添加防老剂A7750的胶料在保有添加防老剂4030胶料性能的基础上，耐屈挠性能提高，解决了防老剂4030液体特性导致的应用局限。 |
| 英文摘要: |
| The application of antioxidant A7750 in sidewall compound of tires was studied. The results showed that compared to the compound with antioxidant 4020，the compound with antioxidant 4030 exhibited better static ozone aging resistance and migration discoloration resistance.The flex resistance of the compound with antioxidant A7750 was improved，while maintaining the properties of antioxidant 4030 compound，addressing the application limitations caused by the liquid characteristics of antioxidant 4030. |
