Abstract

The invention belongs to the technical field of rubber, and particularly relates to sidewall rubber as well as a preparation method and application thereof. The sidewall rubber material comprises matrix rubber, a filler, an active agent, an anti-aging agent, resin and a vulcanizing agent, the matrix rubber comprises natural rubber and butadiene rubber, the butadiene rubber is rare earth modified butadiene rubber, the tail end of the butadiene rubber is provided with an active group, on one hand, the modified butadiene rubber is good in molecular chain flexibility and heat resistance, and on the other hand, the modified butadiene rubber is not prone to falling off; on the other hand, the butadiene rubber molecular chain with the active group promotes the dispersion of the filler, and the filler with good dispersity can reduce the free movement of the polymer molecular chain in the sidewall rubber material, so that the hysteresis energy loss of the sidewall rubber material is reduced, and the service life of the sidewall rubber material is prolonged. And the endurance mileage of a new energy automobile and a traditional fuel automobile is improved.

Description

technical field

[0001] The application belongs to the technical field of rubber, and in particular relates to a sidewall rubber material and its preparation method and application. Background technique

[0002] Compared with traditional fuel vehicles, the cruising range of new energy vehicles is shorter. By reducing the rolling resistance of the tires of new energy vehicles, the energy consumption caused by dynamic deformation and frictional heat generation during tire rolling can be reduced, and the cruising range of new energy vehicles can be improved. .

[0003] Since the tire tread is in direct contact with the ground, if the dynamic deformation is small, the tire grip effect will be poor. Therefore, in the prior art, the tire is improved by reducing the heat generation of the rubber material of the tire tread, and obtaining low rolling resistance. Tires, thereby reducing the process of energy loss in the form of heat, and improving the mileage of new energy vehicles. H...
