摘　　要：研究超长效防护蜡HG72C(简称防护蜡HG72C)在半钢子午线轮胎胎面胶和胎侧胶中的应用。结果表明:与普通防护蜡H3236相比,防护蜡HG72C的色谱峰呈双峰分布,异构烷烃质量分数较大;在胎面胶和胎侧胶中防护蜡HG72C均表现出优异的耐屈挠疲劳性能和耐臭氧老化性能,在硫化胶中形成的蜡膜较薄、表面平整、光滑、致密,起到了很好的防护效果,保持了轮胎良好的外观。The application of super long-term protective wax HG72C(referred to as protective wax HG72C)in the tread and sidewall compounds of steel-belted radial tires was studied.The results showed that the chromatographic peaks of the protective wax HG72C were bimodal and the mass fraction of isoparaffins was higher than that of the common wax H3236.The tread and sidewall compounds with protective wax HG72C showed excellent flexural fatigue resistance and ozone aging resistance.The HG72C wax film formed in vulcanizate was thin,flat,smooth and dense,which had a good protective effect and maintained the good appearance of the tire.
