Abstract

The invention discloses a speed-competing tread rubber for a motorcycle.The speed-competing tread rubber for the motorcycle is prepared from, by weight, 70-100 parts of emulsion polymerized styrene-butadiene rubber, 30-60 parts of solution polymerized styrene-butadiene rubber, 10-25 parts of operation oil, 70-100 parts of high-hysteresis carbon black, 1-3 parts of stearic acid, 3-6 parts of zinc oxide, 2-4 parts of an anti-aging agent, 1-3 parts of microcrystalline wax, 2-5 parts of tert butyl phenolic resin, 4-7 parts of tackifying resin, 1-2.5 parts of sulphur powder and 2-3.5 parts of a promoting agent.By means of the speed-competing tread rubber for the motorcycle, the tread rubber can generate extremely high hysteresis loss in a high-speed movement state of the motorcycle, meanwhile, extremely high dynamic modulus can be kept, friction force between a tread and the ground is increased, a tire has outstanding grip performance and manipulation performance, the defect that the abrasion resistance of the tread is poor can be effectively avoided, optimal performance balance is achieved, and maximization of benefits of a user is achieved.

Description

technical field [0001] The invention belongs to the technical field of tire rubber, and in particular relates to a motorcycle racing tread rubber material. Background technique [0002] At present, the tire tread rubber configuration mainly includes natural rubber, butadiene rubber, styrene-butadiene rubber, reinforcing carbon black, leveling agent, zinc oxide, stearic acid, anti-aging agent, protective wax, accelerator, sulfur and anti-scorch agent, etc. . The tread rubber is in contact with the ground, and it is required to have wear resistance, impact mitigation, anti-skid, driving and braking functions. The tread rubber formula of traditional tires, its wear resistance, safety and grip are mutually restrained, and it is impossible to achieve a comprehensive balance. [0003] With the rapid development of the automobile tire industry, customers have higher and higher requirements for the quality of passenger tires. The high quality of tires mainly includes tire safety,...
