Problems solved by technology

Using the sandwich rubber solution greatly increases the complexity of the tire processing process, and at the same time, due to the problem of poor bonding between the two phases, it may reduce the safety of the tire
In addition, the increase of transverse grooves on the tread pattern will affect the handling stability of the tire

Abstract

The invention relates to the technical field of rubber and particularly relates to a preparation method of a tire tread composite material with high wet and skid resistance. The composite material is characterized by containing the following materials in parts by weight: 100 parts of dienes rubber (concretely including styrene butadiene rubber, butadiene rubber, natural rubber, integrated rubber and a composite of the integrated rubber), 50-80 parts of stuffing (concretely including carbon black, white carbon black and a composite of the white carbon black), 0-6.4 parts of silane coupling agent, 0.5-3 parts of silicon carbide,10-40 parts of plasticizer, 2-5 parts of zinc oxide, 1-3 parts of stearic acid, 2-4 parts of anti-aging agent, 2-4 parts of accelerant and 1-3 parts of sulphur. By adoption of the material prepared by the method, the rolling resistance of a tire can be reduced, the wear-resisting property of the tire tread is not affected simultaneously, and especially, the wet and skid resistance of the tire is greatly increased by utilizing the nano silicon carbide material.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a preparation method of a tire tread rubber composite material with high wet skid resistance. Background technique [0002] Anti-wet skid performance is a key indicator to measure the driving safety of a car, especially on wet and slippery road conditions. With the development of automobile power technology and modern highways, the driving speed of automobiles has been greatly improved compared with the past, so the anti-wet performance of tires is more important. From the perspective of rubber viscoelasticity, the wet skid resistance of tread rubber can be characterized by the tan δ value at 0°C in the dynamic viscoelastic spectrum. The high tan δ value at 0°C indicates that the rubber has good wet skid resistance. Only through the viscoelasticity of rubber, that is, the value of tan δ at 0°C, it is not very accurate to judge the wet skid resistance of the tread material. When ...
