| 中文摘要: |
| 研究航空轮胎胎面胶中防老剂D的替代材料。结果表明：在防老剂4020、3100和AW-66三种防老剂中，胺类防老剂4020是较理想的防老剂D替代品；防老剂4020替代防老剂D后，胶料的硫化时间缩短，硫化速度加快，为保证工艺性能并达到相同的防护效果，需对防老剂4020和促进剂DZ用量同时进行调整；当采用1.3份防老剂4020增量替代1份防老剂D，同时促进剂DZ用量由0.9份调整至0.6份时，胶料的硫化特性、物理性能和耐老化性能优异；成品航空轮胎胎面胶的物理性能良好。 |

| The study on substitude material for antioxidant D in tread compound of aircraft tire was investigated.The results showed that，among the antioxidant 4020，3100 and AW-66，the antioxidant 4020 was an ideal substitude material.With antioxidant 4020 to replace antioxidant D，the curing time of compounds was shorter and the curing rate was faster.In order to ensure the process performance and achieve the same protect effect，the dosage of antioxidant 4020 and accelerator DZ should be adjusted.When using 1.3 phr antioxidant 4020 instead of 1.0 phr antioxidant D in the tread compound and adjusting the dosage of accelerator DZ from 0.9 phr to 0.6 phr，the curing characteristics，physical properties and aging resistance of the vulcanizates were better.The physical properties of the tread compound of finished aircraft tire were good. |
