抗龟裂剂D-99在工程机械轮胎胎面胶和胎侧胶中的应用

Application of Anti-cracking Agent D-99 in Tread and Sidewall Compound of OTR Tire

研究抗龟裂剂D-99在工程机械轮胎胎面胶和胎侧胶中的应用。结果表明:添加2份抗龟裂剂D-99,胎面胶及胎侧胶的挤出和成型工艺性能良好,硫化特性和拉伸性能变化不大,生热降低,弹性、耐屈挠龟裂性能、耐磨性能、耐热老化性能和耐天候老化性能提高;成品轮胎的物理性能改善,使用寿命延长。

In this study, the effect of anti-cracking agent D-99 on the properties of tread compound and sidewall compound of OTR tire was investigated. The experimental testing results showed that with 2 phr of D-99, the extrusion and molding properties of the compounds were good, the curing characteristics of the compounds and the tensile properties of the vulcanizates changed little, but heat build-up was reduced, and the elasticity, flex cracking resistance, wear resistance, heat aging resistance and weathering resistance were improved. The physical properties of the finished tire were improved and the tire service life was extended.
