抗龟裂剂D-99在农业子午线轮胎中的应用

Application of Crack Resistant Additive D-99 in Agriculture Radial Tire

研究抗龟裂剂D-99在农业子午线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,胎面胶和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。

The application of crack resistant additive D-99 in the tread compound and side wall compound of agriculture radial tire was investigated. The test results showed that,when the addition level of D-99 was 2 phr,the extruding and forming process of tread compound and side wall compound was good,curing characteristic and tensile properties changed little,heat build-up was reduced,elasticity,flex crack resistance,abrasion resistance,heat aging resistance and weathering resistance were improved,the physical properties of finished tire were improved,and the service life was prolonged.
