Abstract

The invention provides a tread compound with high wet slip resistance and low rolling resistance for a tire and a synthetic method of the tread compound. The tread compound for the tire comprises thefollowing components, in parts by weight: 100 parts by weight of a rubber component, 50-90.0 parts of high-dispersion white carbon black, 5.0-15.0 parts of carbon black, 7.0-15.0 parts of environmentally-friendly oil, and 10.0-30.0 parts of a rubber additive, wherein the rubber component comprises the following materials: 0.0-40.0 parts of composite polyisoprene rubber, 35.0-55.0 parts of environmentally-friendly oil filled solution polymerized styrene-butadiene rubber and 40.0-60.0 parts of modified solution polymerized styrene-butadiene rubber. According to the tread compound provided by theinvention, the polymerized styrene-butadiene rubber ensures good processability while providing certain wet slip resistance to the rubber compound; and the composite polyisoprene rubber is added, sothat elasticity of the rubber compound is improved, heat generation is reduced, and rolling resistance of the tire is reduced.

Description

technical field [0001] The invention relates to a high-wet-skid-resistant and low-rolling-resistance tire tread compound and a synthesis method, belonging to the technical field of tire production. Background technique [0002] With the development of the automobile industry, automobiles have become an indispensable means of transportation in people's lives, which also makes people put forward higher requirements for the handling safety, fuel-saving performance and comfort of tires during driving, especially for export For tires in some EU countries, clear performance requirements have been established for tire wet grip (handling safety), rolling resistance (fuel-saving performance) and noise (comfort). [0003] The tread part of the tire is the only position that touches the road surface, so it has a decisive impact on the overall performance of the tire, that is, improving the wet performance and rolling resistance of the tread compound can greatly improve the performance ...
