| 中文摘要: |
| 研究物理防老剂（微晶蜡A）和化学防老剂（防老剂RD，3100和4020）对轮胎胎侧胶耐臭氧老化性能和耐天候老化性能的影响。结果表明：与未添加防护体系的硫化胶相比，添加化学防老剂或微晶蜡A的硫化胶耐臭氧老化性能提高，微晶蜡A的防护效果较好；添加微晶蜡A的硫化胶耐天候老化性能大幅提高；添加化学防老剂和微晶蜡A的硫化胶耐臭氧老化性能和耐天候老化性能最佳；成品轮胎行驶50 000 km后，胎侧弹性良好，胎面和胎侧均没有裂纹产生，轮胎使用正常。 |
| 英文摘要: |
| The effect of physical antioxidant（microcrystalline wax A） and chemical antioxidant （antioxidant RD，3100 and 4020） on ozone aging resistance and weather aging resistance of tire sidewall compound was investigated.The results showed that，compared with the vulcanizate without protective system，the ozone aging resistance of vulcanizate with chemical antioxidant or microcrystalline wax A was improved，and the protective effect of microcrystalline wax A was better.The weather aging resistance of vulcanizate with microcrystalline wax A was greatly improved.The ozone aging resistance and weather aging resistance of vulcanizate with chemical antioxidant and microcrystalline wax A were the best.After 50 000 km of driving，the sidewall compound of finished tire kept good elasticity，there was no cracks on the tread and sidewall，and the tire was used normally. |
