Problems solved by technology

The invention improves the passability and safety of ice and snow roads. The material of the snow tire tread is soft, and the silica compound rubber formula can be in closer contact with the smooth ice surface, thereby generating greater friction than four-season tires. The handling and safety of the vehicle on slippery ice are improved, but as a kind of snow tire, its wet skid resistance needs to be further improved

Abstract

The invention belongs to the technical field of tire manufacturing, and particularly relates to a wet-skid-resistant snowfield tire tread rubber and a preparation method thereof. The tread rubber comprises the following components in parts by weight: 35-65 parts of solution-styrene butadiene rubber, 15-45 parts of natural rubber, 20-50 parts of cis-1,4-polybutadiene rubber, 2-5 parts of zinc oxide, 1-4 parts of stearic acid, 1-5 parts of anti-aging agent, 2-4 parts of protective wax, 10-40 parts of environment-friendly aromatic oil, 35-65 parts of white carbon black, 10-35 parts of carbon black, 3.5-6.5 parts of silane coupling agent, 2-7 parts of sulfur and 3-11 parts of accelerator. The tread rubber can obviously lower the hardness of the sizing material and enhance the wear resistance, tear resistance, tensile strength and stress at definite elongation of the sizing material.

Description

technical field [0001] The invention belongs to the technical field of tire manufacturing, and in particular relates to a wet skid-resistant snow tire tread rubber and a preparation method thereof. Background technique [0002] In recent years, people's requirements for automobile safety, comfort, and energy saving have been increasing year by year. Correspondingly, tires are required to have excellent wet skid resistance, wear resistance, and low rolling resistance. These three properties are called "the devil's triangle". Wet skid resistance is one of the mandatory performances, especially on icy and snowy roads, the higher the wet skid resistance of snow tires, it can be seen that it is one of the important performances of tires. [0003] Document CN103435871A discloses a tread rubber for automobile tires. The automobile tire tread rubber of the present invention is composed of the following raw materials: natural rubber, styrene-butadiene rubber, zinc oxide, stearic aci...
