摘　　要：进行了不同防护体系对载重轮胎胎面胶耐臭氧老化性能的影响研究,采用不同配比的防老剂如常用的防老剂4010NA、防老剂4020和防老剂RD、防护蜡并用的防护体系进行研究与应用。结果表明:①载重轮胎采用该3种防老剂并用时最佳总用量范围应控制在5.5份左右,其中防老剂4010NA3.0份、防老剂4020 1.0份、防老剂RD1.5份所取得的防护臭氧效果最好;②在选择防护体系时要同时选择化学防护及物理防护,在动态情况下选择微晶蜡做物理防护效果特好,份数控制在1.5份左右。This article describes the research and application of ozone aging truck tire tread,and research and application are conducted by using different proportions of antioxidants,such as the commonly used antioxidant 4010NA,antioxidant 4020 and antioxidant RD,together with protective wax protection system. The results show that：①best ozone protection can be achieved with truck tires of the three antioxidant when the total amount of range is controlled at about 5.5 parts, including antioxidant 4010NA 3.0,antioxidant 4020 1.0,antioxidant RD1.5;②both chemical protection and physical protection should be considered. Microcrystalline wax gives better physical protection in dynamic case,where the number of copies is controlled at about 1.5 parts.
