Abstract

The invention discloses a tire tread rubber material with high grip performance and low rolling resistance. The tire tread rubber material with high grip performance and low rolling resistance comprises: SSBR6270 40-44% by weight percentage , natural rubber SIR20 12-15%, highly dispersed silica 26-30%, antioxidant 2.0-3.0%, coupling agent X-50S 3-5%, active agent 1-3%, plasticizer 2-4 %, 0.6-0.9% vulcanizing agent, 1.2-1.6% accelerator and 0.07-0.1% anti-scorch agent, the combined styrene content of the solution-polymerized styrene-butadiene rubber SSBR6270 is 23.5-26.5%, and the oil content is 25.8-28.8%, The specific surface area of ​​the highly dispersed white carbon black is 200-230m 2 / g, the sum of the contents of each component is 100%. Through the above-mentioned method, the technology provided by the present invention has strong grip performance on dry ground, strong cornering control ability, and small driving rolling resistance. Wetland driving safety factor, durability up to standard.

Description

technical field [0001] The invention relates to the technical field of rubber products, in particular to a tire tread compound with high grip performance and low rolling resistance and a synthesis method thereof. Background technique [0002] A car will generate various driving resistances during driving, 80% of which is air resistance, and the remaining 20% ​​is rolling resistance. According to data, the CO released during the frictional heat generation of tires is currently 2 It has accounted for 3% of the greenhouse gases released by global fossil fuels, and a considerable part of automobile fuel consumption is used to overcome tire frictional resistance. According to the data of the European Commission, the energy consumption required for the rolling resistance of automobile tires accounts for about 20% of the fuel consumption of the whole vehicle. It has been determined that every 7% reduction in tire rolling resistance can reduce vehicle fuel consumption by 1%, and ca...
