白炭黑加工改质剂ATE-W在全钢载重子午线轮胎中的应用

Application of Silica Processing Modification Agent ATE-W in Truck and Bus Radial Tire

研究白炭黑加工改质剂ATE-W在全钢载重子午线轮胎中的应用。结果表明:在胎面胶中加入白炭黑加工改质剂ATE-W,可明显改善白炭黑的分散性,提高胶料的加工性能,降低混炼能耗和排胶温度,对硫化胶的物理性能无不良影响,可提高胎面胶的抗湿滑性能,对成品轮胎的强度和耐久性能无影响;白炭黑加工改质剂ATE-W的应用效果略优于白炭黑分散剂ST。

The application of silica processing modification agent ATE-W in truck and bus radial tire was investigated. The results showed that, by adding ATE-W in the tread compound, the dispersion of silica was significantly improved,the processability of the compound was improved,the mixing energy consumption and discharge temperature decreased, the physical properties of the vulcanizates changed little, the wet skid resistance of the tread compound was improved, and the strength and endurance of the finished tire changed little. The application effect of ATE-W was better than silica dispersing agent ST.
