内脱模剂AT-16-Ⅲ在半钢子午线轮胎胎侧胶中的应用

Application of Internal Releasing Agent AT-16-Ⅲ in Sidewall Compound of Steel-belted Radial Tire

研究内脱模剂AT-16-Ⅲ在半钢子午线轮胎胎侧胶中的应用。结果表明:内脱模剂AT-16-Ⅲ具有良好的内外润滑功能;添加内脱模剂AT-16-Ⅲ的胎侧胶门尼粘度降低,FL减小,F_(max)基本不变,拉伸强度、拉断伸长率和撕裂强度提高,生热降低;胎侧胶添加内脱模剂AT-16-Ⅲ可以明显减少轮胎胎侧缺胶问题,提高轮胎的一次合格率。

The application of internal releasing agent AT-16-Ⅲ in the sidewall compound of steel-belted radial tire was studied.The results showed that the internal releasing agent AT-16-Ⅲ had good internal and external lubricating function,and the Mooney viscosity of the compounds with internal releasing agent AT-16-Ⅲdecreased,FL was reduced,Fmax was basically unchanged,the tensile strength,elongation at break and tear strength of the vulcanizates were improved,and the heat build-up was reduced. Addition of internal releasing agent AT-16-Ⅲ could significantly reduce the problem of insufficient rubber fill-out in the sidewall and improve the first time pass rate of the tire.
