Abstract

The invention discloses a wear-resistant rubber material combination of a tire tread and a preparation method thereof. The combination includes: natural rubber, styrene butadiene rubber, butadiene rubber, carbon black, zinc oxide, stearic acid, an anti-aging agent, sulfur, a distillate aromatic extract, a promoter, a reinforcing agent, a tackifier and a dispersing agent, wherein the distillate aromatic extract is a high aromatic hydrocarbon oil, the tackifier is C5 resin and the carbon black is N110 and N234. The combination also can comprise white carbon black. The combination is prepared through a plasticating process, a mixing process and an open mixing process and the like. A rubber material which is prepared from the wear-resistant rubber material combination of the tire tread and through the preparation method thereof has a better tearing strength, a better tensile strength and a better hardness. With the wear-resistant raw materials and a reasonable design of the combination components, hidden dangers on an operator during a production process and on a user during a using process are significantly reduced. The rubber material is higher in safety, is better in economy and is wider in adaptation. The wear-resistant rubber material combination of the tire tread is completely in conformity with related national and industrial requirements. Meanwhile, a usage performance of a tire is far higher than a usage standard requirement of a conventional tire in the prior art. The tire tread has characteristics of high wear resistance and excellent performance.

Description

technical field [0001] The invention belongs to a tire tread rubber combination and a preparation method thereof, in particular to a wear-resistant tire tread rubber combination and a preparation method thereof. Background technique [0002] Tires are made of a variety of materials. The service life of an ordinary tire is particularly concerned. Most of the tire damage is caused by the short-term wear of the tread. More and more attention has been paid to it, and wear-resistant tires have also become the development trend of the tire industry. People pay more and more attention to the coexistence of tire wear resistance and performance, but there are generally two situations in terms of the current tire form: one is that the performance of the tire can meet the national standard and the needs of consumers, but the tire cannot meet the wear resistance requirements of customers The 2nd, tire can reach the requirement of wear resistance, but the comprehensive performance of ti...
