The local strong repeated force reduces the physical bonding points in the tread compound, and at the same time, the carbon black aggregates and some rubber molecular chains form layered anisotropy; this anisotropic structure formed by both microstructure and macrostructure As a result, the tear strength of the circumferential region parallel to the layered structure decreases, and the damage develops along the rubber layer with increased free volume and the lowest strength in the layered anisotropic structure, forming a kind of interlayer failure of layered peeling, and finally Resulting in a reduction in the tread life of OTR tires

Abstract
The invention relates to the field of tire rubber formula, especially to a cut-resistant all-steel engineering tire tread rubber material and a preparation method and application thereof. The tread rubber material is prepared from raw materials which contain the following ingredients (by weight): 100 parts of styrene-butadiene rubber, 0.1-3.5 parts of bentonite, 45-60 parts of carbon black, 2-6 parts of zinc oxide, 0.5-2 parts of stearic acid, 9-12 parts of environment-friendly oil, 0.5-2 parts of 6PPD, 1-3 parts of an anti-aging agent RD, 1-3 parts of oiled sulphur and 1-3 parts of an accelerant CZ. By preblending bentonite, styrene-butadiene rubber and carbon black, dispersibility is raised. In comparison with wet blending in a solution, the preblending in the invention is more convenient to operate. By adding a few amount of bentonite into the bentonite / carbon black / styrene-butadiene rubber composite material and by the characteristics of the bentonite sheet material and by synergism of the bentonite sheet material and carbon black, properties such as cut resistance of the engineering tire tread rubber material are improved.
Description
technical field [0001] The invention relates to the field of tire compound formulations, in particular to a cut-resistant all-steel engineering tire tread compound and its preparation method and application. Background technique [0002] The tread of engineering tires will often come into contact with sharp stones or roadside stones repeatedly under harsh and complex road conditions, and the tread rubber will tear and collapse. The local strong repeated force reduces the physical bonding points in the tread compound, and at the same time, the carbon black aggregates and some rubber molecular chains form layered anisotropy; this anisotropic structure formed by both microstructure and macrostructure As a result, the tear strength of the circumferential region parallel to the layered structure decreases, and the damage develops along the rubber layer with increased free volume and the lowest strength in the layered anisotropic structure, forming a kind of interlayer failure of ...
