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 alternative material for antioxidant D in the 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 alternative material for antioxidant D.With antioxidant 4020 to replace antioxidant D,the curing time of the compounds was shortened and the curing rate increased.In order to ensure the process performance and achieve the same protective effect,the dosage of antioxidant 4020 and accelerator DZ should be adjusted at the same time.When 1.3 phr antioxidant 4020 was used to replace 1.0 phr antioxidant D in the tread compound and the dosage of accelerator DZ was adjusted from 0.9 phr to 0.6 phr,the curing characteristics,physical properties and aging resistance of the vulcanizates were excellent,and the physical properties of the tread compound of the finished aircraft tire were good.
