Description
Technical Field
The application belongs to the technical field of rubber tires, and particularly relates to a tread rubber composition for preparing a high-performance all-steel radial tire, a mixing method of the tread rubber composition and a tire.
Background
As the economic development and the road driving condition become better, the truck and passenger cars begin to pay more attention to the oil consumption and mileage of the tires, and higher requirements on rolling resistance and wear resistance of the tires are made. According to the research, the rolling resistance of the heavy-duty tire is reduced by 3%, the oil is saved by 1%, and the tire has great economic value in reducing the rolling resistance of the tire. With the implementation of the tire labeling law of various countries, higher requirements are put on the rolling resistance of the heavy-duty radial tire.
At present, one of the effective means for reducing the rolling resistance of tires is to adopt biphase carbon black, white carbon black and a silane coupling agent to achieve the effect of reducing the rolling resistance. In general, wear resistance of the tread rubber is reduced by using the carbon black and the carbon black together with the two-phase carbon black, so that mileage is reduced while oil is saved, service life of the tire is reduced, and tire cost is not substantially reduced. In the tire industry, magic triangle rolling resistance, wear resistance and wet gripping are permanent subjects, and a means is hoped to be found to break the balance, so that the rolling resistance is reduced, and meanwhile, the wear resistance of the tread rubber is improved. Therefore, the requirement of improving the wear resistance of the heavy-duty radial tire and reducing the rolling resistance becomes an important subject of tire developers.
At present, Chinese patent application (publication No. CN110283364A) reports that one or more other hydrazides of the same type as isophthaloyl hydrazine can reduce heat generation in a tire side formula, but does not consider the synergistic effect of 1, 6-bis (N, N' -dibenzothiazyl carbamyl disulfide) -hexane on other performances such as abrasion, and the preparation method of the composition has the defect that Mooney is rapidly increased by adding hydrazide into a butadiene-containing rubber composition, so that the dispersion of a filler in natural rubber and butadiene rubber is influenced.
The Chinese patent application (publication No. CN109251375A) reports that isophthaloyl hydrazine can reduce heat generation and improve fatigue performance in engineering tire treads, and only the effect of isophthaloyl hydrazine is considered, but the synergistic effect with 1, 6-bis (N, N' -dibenzothiazyl carbamyl disulfide) -hexane is not considered. The adopted 1, 6-bis (N, N' -dibenzothiazyl carbamyl disulfide) -hexane participates in the reaction to form thermodynamically stable monothio bond, disulfide bond and mixed crosslinking bond with similar polysulfide bond flexibility, so as to ensure that the tread has good wear resistance and low hysteresis.
The Chinese patent application (publication number: CN106832448B) reports that 1, 6-bis (N, N '-dibenzothiazyl carbamyl disulfide) -hexane used in a tread has the characteristics of low heat generation and good wear resistance, and the synergistic effect of isophthaloyl hydrazine is not considered, so that the heat generation reduction and the wear resistance improvement of the method are not obvious in the synergistic effect of isophthaloyl hydrazine and 1, 6-bis (N, N' -dibenzothiazyl carbamyl disulfide) -hexane. The technical problem that the abrasion resistance of the tire is reduced while the rolling resistance of the tire is reduced is effectively solved by utilizing the synergistic effect of isophthaloyl hydrazine and 1, 6-bis (N, N' -dibenzothiazyl carbamyl disulfide) -hexane.
