Winter tread rubber material

Abstract

The invention provides a winter tread rubber material comprising, in parts by weight, 35-50 parts of natural rubber, 10-15 parts of high vinyl polybutadiene rubber, 50-60 parts of oil filled neodymium cis-butadiene rubber, 15-20 parts of mineral oil MES, 6-8 parts of high-structural carbon black, 60-75 parts of high-dispersion white carbon black, 5-7 parts of a silane coupling agent, 3-5 parts of a processing aid, 1-3 parts of zinc oxide, 1.5-3 parts of stearic acid, 2-3 parts of an anti-aging agent 4020, 1-2 parts of microcrystalline wax, 5-8 parts of aliphatic hydrocarbon tackifying resin, 0.5-1.5 parts of a sulfur powder, 1.5-2.5 parts of an accelerator, and 6-10 parts of a regenerated rubber powder. The winter tread rubber material is still in a relatively soft state under an environment of relatively low temperature, the friction between a tread and the ground is large, and the safety of a vehicle driving under the environment of low temperature is ensured; the wear resistance of the tread can be improved, the use cost is reduced, user benefits are maximized, and the pollution to the environment is reduced; and wet skid resistance and heat generation property of the rubber material both have excellent representation and fully conform to the road holding requirements of wet road surfaces.

Description

technical field [0001] The invention relates to the technical field of tire rubber, in particular to a rubber material for winter treads. Background technique [0002] With the increase of the number of cars in our country, car safety has increasingly become a common concern, among which the reliability and safety of tires is one of them. Nowadays, whether it is from the perspective of the industry or users, the technical requirements for the quality of tires are getting higher and higher, especially for winter tires, which generally have poor wear resistance, high rolling resistance and tread rubber at low temperatures. Under the problem that it is easier to harden, the car is very prone to traffic accidents when driving on winter roads. Therefore, there is a need for a stable, reliable winter tread compound to improve the currently used winter tires. Contents of the invention [0003] The object of the present invention is to provide a winter tread compound to solve or...
