Articulated truck tire tread rubber composition and preparation method thereof

Abstract

The invention relates to an articulated truck tire tread rubber composition and a preparation method thereof, belonging to the field of tire production. The articulated truck tire tread rubber composition is composed of the following components in parts by weight: 75-100 parts of natural rubber, 0-25 parts of styrene-butadiene rubber, 50-70 parts of small-particle-size highly-structure-reinforced carbon black, 0-15 parts of silica white, 0-10 parts of tear-resistant resin, 0-3 parts of protective wax, 0-4 parts of N-(1,3-dimethyl butyl)-N'-phenyl-p-phenylenediamine, 0-1 part of acetone-diphenylamine high-temperature condensate, 0-3 parts of stearic acid, 0-10 parts of environment-friendly oil, 0-5 parts of phenol formaldehyde resin tackifier, 0-5 parts of zinc oxide, 0-1 part of anti-reversion agent WK-901, 0-5 parts of dispersing agent, 0-2.5 parts of sulfur and 0.5-2.5 parts of N-cyclohexyl-2-benzothiazole sulfenamide. The articulated truck tire tread rubber composition has the advantages of excellent wear resistance, excellent cutting resistance and excellent thermo-oxidative aging resistance, and can adapt to the operating requirements of high wear resistance, high cutting resistance and excellent thermo-oxidative aging resistance for the articulated truck tire tread rubber.

Description

technical field [0001] The invention relates to a technology in the field of tires, in particular to a wear-resistant and cut-resistant tread rubber composition suitable for hinged truck tires on harsh roads and a preparation method thereof. [0002] Background technique [0003] Due to its special structure, the articulated truck is a vehicle that can be used in harsh weather and rough road conditions, such as sandy land, deep pits, quarries, mines, tunnels, etc. Some areas in southern my country are in a hot and rainy environment all year round, with muddy ground, sharp soil and rocks, and extremely poor road conditions. Articulated trucks are the primary transport vehicles in this work environment. Therefore, higher requirements are put forward for the wear resistance and cutting resistance of the tires used. At the same time, because articulated trucks generally travel faster, and because rubber is a poor conductor of heat, it is difficult for tires to dissipate heat....

AI Technical Summary

Problems solved by technology

At the same time, because articulated trucks generally travel faster, rubber is a poor conductor of heat, and it is difficult for tires to dissipate heat. Under the action of strong force caused by high speed, high temperature, and uneven road surface, the rubber material is prone to thermal oxygen aging. Seriously affect the service life of tires, so the tread rubber for hinged truck tires on harsh roads needs to have excellent heat and oxygen aging resistance
