摘　　要：考察高二聚体含量防老剂TMQ部分替代防老剂4020在全钢载重子午线轮胎胎体胶中的应用。结果表明:与防老剂4020胶料相比,防老剂4020/TMQ并用的胶料加工安全性能稍好,物理性能变化不大;减小防老剂TMQ用量对胶料耐热氧老化性能影响不大;防老剂TMQ在一定程度上影响钢丝-橡胶的粘合性能,防老剂S-TMQ用量1.05份和防老剂4020用量1份的胶料粘合性能较好,性价比较高。The application of antioxidant TMQ with high dimer content to partially replace antioxidant 4020 in the carcass compound of TBR tire was investigated. The scorch safety of the compound was slightly improved while the physical properties change little. Adding antioxidant TMQ has little influence on the thermal oxidative aging resistance, but could improve the adhesion between steel cord and rubber compound. With 1.05 phr of antioxidant S-TMQ and 1 phr of antioxidant 4020, the adhesion was good and the cost/performance ratio was better.
