The invention relates to high-performance and high-wear-resistance tire tread rubber and a preparation method thereof. The tire tread rubber is prepared from the following raw materials: natural rubber, carbon black, white carbon black, graphene, nano aluminum oxide, zinc oxide, stearic acid, a silane coupling agent, an anti-aging agent, a dispersing agent, an accelerant, a scorch retarder and sulfur. Nano-alumina and a silane coupling agent are subjected to a chemical reaction, the binding force between the nano-alumina and rubber is enhanced, the binding force between rubber macromolecular chains is enhanced, graphene is a two-dimensional nano-carbon material, a small amount of oxygen-containing groups on the surface are combined with the rubber macromolecular chains in a rubber vulcanization reaction, and the binding force between the rubber macromolecular chains is also enhanced; according to the tread rubber, through the synergistic effect of all the raw materials, the wear resistance and physical performance of the tread rubber are improved, and the preparation method is simple and suitable for large-scale production.
