| titleOfInvention | High-performance tire tread rubber and preparation method thereof |
| abstract | The invention relates to a high-performance tire tread rubber and a preparation method thereof. The tire tread rubber comprises the following components in parts by mass: 60-90 parts of natural rubber, 0-20 parts of butadiene rubber, 9-20 parts of low-molecular-weight trans-butadiene-isoprene copolymer rubber, 40-60 parts of carbon black, 0-20 parts of white carbon black, 0-2 parts of a silane coupling agent, 1-5 parts of zinc oxide, 1-5 parts of stearic acid, 0.3-3 parts of sulfur, 0.5-5 parts of an accelerator, 1-3 parts of an anti-aging agent and 1-10 parts of other auxiliary agents. The invention adopts low molecular weight trans-butadiene-isoprene copolymer rubber to modify the tire tread rubber, the vulcanized rubber has the advantages of improving the tensile strength by 15-20%, improving the tearing strength by 1-20%, reducing the loss factor at 60 ℃ by 4-20% and reducing the abrasion by 10-25%. Various performances of the tire tread rubber sizing material provided by the invention meet the performances of tire tread rubber. |
