Abstract

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.

Description

technical field [0001] The invention relates to a rubber composition for reinforcing semi-steel tire treads with white carbon black, which belongs to the technical field of tire and rubber processing. Background technique [0002] With the development of the tire industry, people pursue low rolling resistance (energy saving), high wet skid resistance (driving safety) and good resilience (riding comfort) among various tire performances. Therefore, there is a strong demand for high-performance tires for vehicles, that is, tires with safety, energy saving, durability, and environmental protection functions. In order to seek to develop rubber for tires that can meet this performance requirement, a lot of scientific research work has been done at home and abroad, and great progress has been made, among which high vinyl polybutadiene rubber (HVPBR) is one example. Because the molecular chain contains a large number of vinyl side groups (vinyl structure content ≥ 70%), the saturat...
