Abstract

The invention discloses a tire tread rubber material with high road-holding performance and low rolling resistance. The rubber material comprises, by weight percentage, 40-44% of solution-polymerizedstyrene-butadiene rubber SSBR6270, 12-15% of natural rubber SIR20, 26-30% of high-dispersing white carbon black, 2.0-3.0% of an antioxidant, 3-5% of a coupling agent X-50S, 1-3% of an activating agent, 2-4% of a plasticizer, 0.6-0.9% of a vulcanizing agent, 1.2-1.6% of an accelerator and 0.07-0.1% of an anti-scorching agent, the bound styrene content of the solution-polymerized styrene-butadiene rubber SSBR6270 is 23.5-26.5%, the oil content is 25.8-28.8%, the specific surface ratio of the high-dispersing white carbon black is 200-230 m<2>/g, and the total content of all components is 100%. According to the tire tread rubber material, the dried land road-holding force performance is high, the cornering manipulative capability is high, the driving rolling resistance is low, better wet landroad-holding force, wet land manipulative capability and icy and snowy land road-holding force are achieved, the wet land driving safety coefficient can be improved, and the wearing resistance meets the standards.

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...
