摘要
研究氧化锌预分散母胶粒在无内胎全钢载重子午线轮胎气密层胶中的应用。结果表明:采用氧化锌预分散母胶粒(氧化锌质量分数为0. 8)替代粉状氧化锌,氧化锌在胶料中的分散性明显提高,胶料门尼粘度减小,加工安全性改善,炭黑分散等级和气密性明显提高,综合性能较好。
The application of pre-dispersed zinc oxide masterbatch in the inner liner compound of tubeless all-steel radial truck tire was studied. The results showed that,by using the pre-dispersed masterbatch in which the mass fraction of zinc oxide was 0.8 instead of powdered zinc oxide,the dispersion of zinc oxide in the compound was obviously improved,the Mooney viscosity of the compound was reduced,the processing safety was improved,the dispersion grade of carbon black and the air tightness of the vulcanizate were obviously improved,and the comprehensive performance was better.
