The invention relates to a white carbon black reinforced rubber composition for semi-steel tire treads, and belongs to the technical field of tire and rubber processing. The composition comprises, by mass, 50-60 parts of HVPBR, 40-50 parts of NR, and 50-70 parts of white carbon black; and a processing assistant and a filler can be added according to routine tread rubber performances. The high wet skid resistance and the low rolling resistance of the HVPBR containing a branched structure are used, the branched structure is in favor of realizing rubber and white carbon black blending and realizing processing performances and the mechanical strength of the NR, and the HVPBR, the NR and the white carbon black are compounded and are used in the production of tire treads. Compared with synthetic rubber materials for traditional semi-steel tire treads, high vinyl polybutadiene (HVPBR) has the advantages of low cost, improvement of the compatibility of the white carbon black and the rubber material, improvement of the processing performances, guaranteeing of excellent wet skid resistance, reduction of the rolling resistance and the dynamic heating of the treads, and no obvious traction loss.
