The invention relates to a rubber composition, in particular to a method for preparing tread rubber through biphase carbon black masterbatch together with white carbon black and an application thereof. The biphase carbon black masterbatch and white carbon black filler or white carbon black masterbatch are used at the same time. The method includes the following steps that the biphase carbon black masterbatch and the white carbon black filler or the white carbon black masterbatch are added into an internal mixer; then a coupling agent, an anti-ageing agent, an active agent, oil and one or more of other processing agents are added; afterwards, a vulcanizing agent and an accelerator are added to be evenly mixed and then a rubber compound is obtained; the rubber compound is vulcanized, and accordingly vulcanized rubber of the tread rubber is obtained. According to the tread rubber obtained after the raw materials are used at the same time, the hysteresis loss reaches the level of pure white carbon black tread rubber, and the abrasion resistance is superior to that of the pure white carbon black tread rubber and is equivalent to that of biphase carbon black tread rubber.
