摘　　要：研究白炭黑分散剂HT254(脂肪酸胺)、H60EF(锌皂/钾皂混合物)和HST(锌皂/多元醇酯混合物)在轮胎胎面胶中的应用。结果表明:在胎面胶中添加白炭黑分散剂,混炼胶的混炼能耗和门尼粘度降低,硫化速度加快,加工性能改善;白炭黑分散剂与偶联剂具有协同作用,显著改善白炭黑在胶料中的分散性,降低胶料滚动阻力,提高胶料抗湿滑性能和耐磨性能;不同白炭黑分散剂对白炭黑分散性的改善效果不同,添加白炭黑分散剂H60EF的胶料综合性能最佳。In this paper,application of silica dispersing agents,HT254（fatty amine）,H60EF（mixture of zinc soap and potassium soap） and HST（mixture of zinc soap and polyol ester）,in the tire tread compound was presented. The experimental testing results showed that,with the addition of silica dispersing agent,the mixing energy consumption and Mooney viscosity of the tread compound were reduced,and the curing speed increased,indicating improved processing properties. The silica dispersing agent showed a synergistic effect with silane coupling agent,and thus the silica dispersion was further improved,the rolling resistance was reduced,wet skid resistance and abrasion resistance were improved. It was found that the effect of different dispersing agents was different and the overall properties of the compound with H60 EF were the best.
