Problems solved by technology

Ordinary low rolling resistance tread rubber, although it has low rolling resistance, has the disadvantages of non-abrasion resistance and poor wet skid resistance. We invented low rolling resistance while maintaining good wear resistance and moisture resistance. The tread compound formula with slippery performance is of great significance to reduce the rolling resistance of tires

Abstract

The invention provides a low rolling resistance tire rubber material with an ultrahigh wear resistance, which contains low temperature emulsion polymerized oil charge styrene butadiene rubber SBR1723, low temperature emulsion polymerized oil charge styrene butadiene rubber SBR1739, butadiene rubber BR9000, high structure medium and ultra wear resistant furnace black, high dispersion white carbon black, coumarone resin COUMARONE RESINCY-CR1 tackifying resin; GOYENCHEM-GR80 tackifying resin, antiager, vulcanizing agent, coupling agent X-50S, activating agent and accelerant. The low rolling resistance tire rubber material with the ultrahigh wear resistance is superior to a common tire in rolling resistance, wet road holding capacity, ice road holding capacity and wear resistance. The tire has better wet road holding capacity, a wet land driving safety coefficient is improved, ultrahigh wear resistance is realized, high speed performances are excellent and comprehensive use performances of a tire are improved.

Description

technical field [0001] The invention relates to the field of rubber products, in particular to a tire tread compound with ultra-high wear resistance and low rolling resistance. Background technique [0002] When a car is running, it will produce various driving resistances, 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; 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 by the rolling resistance of automobile tires accounts for about 20% of the fuel consumption of the whole vehicle. In other words, one out of every five oil additions is entirely for the tires. It has been determined that every 7% reduction in tire rolling resistance can r...
