| 中文摘要: |
| 研究稀土防老剂对轮胎胎面胶热氧和臭氧老化前后主要性能的影响，并与防老剂4010NA进行对比。结果表明：稀土防老剂对胶料热氧老化和臭氧老化的防护效果均优于防老剂4010NA；加入稀土防老剂Ⅰ的胶料具有较好的耐切割性能，热氧老化后撕裂强度保持率最大，对臭氧老化的防护效果最优；加入稀土防老剂Ⅱ的胶料经热氧老化后拉伸强度保持率最大，耐磨性能提高。 |
| 英文摘要: |
| The effects of the rare earth antioxidant on the main properties of tire tread compound before and after thermo-oxygen aging and ozone aging were investigated，and compared with antioxidant 4010NA.The results showed that，the protective effects of the rare earth antioxidant on the thermo-oxygen aging and ozone aging were better than those of antioxidant 4010NA，respectively.With rare earth antioxidantⅠ，the cut resistance of the vulcanizates was good，the retention rate of tear strength was the highest after thermo-oxygen aging，and the ozone aging resistance was the best.With rare earth antioxidant Ⅱ，the retention rate of tensile strength was the highest after thermo-oxygen aging，and the abrasion resistance of the vulcanizates was improved. |
