The present invention relates to a tread rubber composition for an electric vehicle tire and a tire. The tread rubber composition comprises: 35-55 wt% of a rubber component, and based on 100 parts byweight of the rubber component, 55-100 parts by weight of a filler, 5-15 parts by weight of an aromatic polymer resin, 0.5-2.5 parts by weight of a guanidine accelerator, and 1.5-5.5 parts by weight of a dispersant, wherein the rubber component comprises solution polymerized styrene-butadiene rubber, and the filler comprises white carbon black and carbon black, and the dispersing agent is selectedfrom polyethylene glycol and N-hydroxyphthalimide. The rubber composition shows low rolling resistance, good road holding performance, excellent wet skid resistance, excellent tensile strength and other properties so that the tire comprising the tread rubber formed by the rubber composition has the excellent properties of low rolling resistance, good road holding performance, excellent wet skid resistance, small initial torque and the like.
本发明涉及一种用于电动汽车轮胎的胎面橡胶组合物和轮胎,其包含35‑55重量%橡胶组分,以及基于100重量份所述橡胶组分,55‑100重量份填料,5‑15重量份芳烃聚合物树脂,0.5‑2.5重量份胍类促进剂,1.5‑5.5重量份分散剂,其中所述橡胶组分包括溶聚丁苯橡胶,和所述填料包括白炭黑和碳黑,所述分散剂选自聚乙二醇和N‑羟基邻苯二甲酰亚胺。本发明的橡胶组合物显示低的滚动阻力、好的抓地性、优异的抗湿滑以及优良的拉伸强度等性能,使得包括由所述橡胶组合物形成的胎面胶的轮胎具有低的滚动阻力、好的抓地性、优异的抗湿滑、初始扭矩较小等优异性能。
