Abstract

The present invention relates to a rubber composition for a high-speed energy-saving tire tread, and belongs to the technical field of tire and rubber processing. The rubber composition comprises the following components: 100 parts by mass of HVPBR, 10-50 parts by mass of white carbon, 0-40 parts by mass of carbon black, and 0-2.7 parts by mass of a silane coupling agent, wherein a total amount of the white carbon and the carbon black is 50 parts by mass. Compared with the conventional rubber material for a tire tread, the rubber composition contains high vinyl polybutadiene with a branched structure, so that the consistency of the white carbon and a rubber material is improved, and the processability is improved. On the premise of ensuring excellent wet traction, the rolling resistance and dynamic heat build-up of the tread are reduced without causing obvious loss of traction force, thereby meeting a development concept of low-carbon economy that is currently advocated.

Description

technical field [0001] The invention relates to a rubber composition for high-speed energy-saving tire tread, which belongs to the technical field of tire and rubber processing. Background technique [0002] In the 1990s, the French company Michelin proposed the concept of green tires and devoted itself to its research work. Major tire companies in Europe, the United States and Japan have accelerated the development of green tires. The so-called green tires refer to tires that can reduce fuel consumption and reduce vehicle exhaust emissions. It has become the mainstream of tire industry development. With the development of automobiles in the direction of high speed, safety, energy saving, and comfort, the requirements for high performance tires are also increasing year by year, which requires tire treads to have good wet skid resistance, excellent wear resistance, and low rolling resistance. resistance characteristics. Since the 1990s, white carbon black has been widely u...
