The invention provides a mixing method for reducing agglomeration of white carbon black in a rubber matrix. A rubber composite material is composed of the following raw materials in parts by weight: raw rubber, white carbon black, a silane coupling agent Si-69, N234 carbon black, an accelerant DPG, a rubber additive and a vulcanizing agent. The invention further provides a preparation method of the rubber composite material containing the white carbon black, the invention provides the mixing method for improving agglomeration of the white carbon black in the rubber matrix, the problems of agglomeration and secondary agglomeration of the white carbon black in the rubber matrix are solved, and the modification effect of the silane coupling agent Si-69 on the surface of the white carbon black is improved. Therefore, the extrusion process performance of the rubber composite material with high content of white carbon black is improved, and the problem of low reinforcing efficiency of the white carbon black is solved.
