Abstract

The present invention provides an ultra-high performance tire tread, wherein the rubber materials of the ultra-high performance tire tread comprise 2-5% of natural rubber, 23-30% of solution polymerized styrene-butadiene rubber A, 6-9% of solution polymerized styrene-butadiene rubber B, 5-10% of a liquid rubber, 30-40% of highly-dispersed carbon black, 6-10% of a tackifying resin, 2-5% of an anti-aging agent, 0.5-0.8% of a vulcanizing agent, 0.2-0.8% of an environmental protection accelerating agent TBZTD-70, and 2-5% of a coupling agent SI75. According to the present invention, with the ultra-high performance tire tread, the extremely short braking distance, the extremely high turning-corner stability, the extremely high safe driving can be provided, and the low rolling resistance can be provided so as to save the fuel consumption; and the ultra-high performance tire tread has good wet road holding capability so as to improve the wet road driving safe factor and make the tire achieve the ultra-high performance standard.

Description

technical field [0001] The invention relates to the field of rubber products, in particular to an ultra-high-performance tire tread and a synthesis method thereof. Background technique [0002] Ordinary high-performance tires have a high flatness ratio, long sidewalls, strong impact capability, and relatively high comfort, but they have poor road feeling and weak lateral resistance when turning. When the flat ratio of the tire is low and the inner diameter is large, the tire wall is short and the tread is wide, so the ground contact area is large, the pressure the tire can bear is also large, the reaction to the road is very sensitive, and the lateral resistance is strong when turning. Strong. [0003] However, when the flatness ratio is low, the contact area between the tire and the road surface is large, which will inevitably increase the rolling resistance of the tire and increase fuel consumption. At the same time, due to the increase of the contact area, the water can...
