The invention provides a tire tread rubber material and a preparation method thereof, and belongs to the technical field of tire tread rubber. The preparation method comprises the following steps: modifying graphene, preparing inorganic composite powder, preparing an auxiliary agent and mixing. The preparation of the auxiliary agent comprises the following steps: placing titanium dioxide in a closed environment for closed treatment at the treatment temperature of 213-219 DEG C, the treatment time of 30-34 minutes and the treatment pressure of 2.0-2.4 MPa, then reducing the temperature to 143-151 DEG C at the rate of 1.7-2.3 DEG C/min, performing closed treatment again for 37-43 minutes at the treatment pressure of 2.4-3.0 MPa, then reducing the temperature to 80-88 DEG C, increasing the pressure to 3.9-4.1 MPa, placing the titanium dioxide in steeping liquor for 23-27 minutes, and drying to obtain the auxiliary agent. The prepared tire tread rubber material is good in cutting resistance and excellent in strength performance, low temperature resistance, ultraviolet radiation resistance and saline dipping resistance.
