The embodiment of the invention relates to the technical field of tire rubber materials, and particularly discloses a tread rubber composition as well as a preparation method and application thereof, and the tread rubber composition comprises the following raw materials: natural rubber, solution polymerized styrene-butadiene rubber, modified white carbon black, sulfur, a vulcanization accelerator, a scorch retarder and a proper amount of an anti-aging agent. According to the embodiment of the invention, through reasonable use of the modified white carbon black and other raw materials, the filler dispersion effect can be effectively optimized, the use of small molecules is reduced, the abrasion and physical and mechanical properties of the tire are improved, and the rolling resistance of the tire is reduced; the problem that in the prior art, a method for reducing the rolling resistance of the tire by increasing the using amount of white carbon black is prone to causing poor dispersing performance of rubber filler is solved. Moreover, the preparation method of the tread rubber composition provided by the embodiment of the invention is simple, and the tread rubber composition has a wide application prospect.

本发明实施例涉及轮胎橡胶材料技术领域，具体公开了一种胎面橡胶组合物及其制备方法和应用，所述胎面橡胶组合物包括以下的原料：天然橡胶、溶聚丁苯橡胶、改性白炭黑、硫磺、硫化促进剂、防焦剂以及适量的防老剂。本发明实施例通过改性白炭黑以及其他原料的合理使用，可以有效优化填料分散效果，减少小分子的使用，提升轮胎的磨耗、物理机械性能并降低轮胎滚动阻力，解决了现有技术中通过增加白炭黑用量来降低轮胎滚动阻力的方法存在易造成胶料填料分散性能变差的问题。而且，本发明实施例提供的胎面橡胶组合物的制备方法简单，具有广阔的应用前景。
