Abstract

The invention belongs to the technical field of new materials, and provides a new wear-resistant tire material and a preparation method thereof. The wear-resistant tire comprises the following raw materials in parts by weight: 50-85 parts of natural rubber, 12-28 parts of chlorohydrin rubber, 8-12 parts of alkali-free glass fiber, 8-23 parts of silicon dioxide, 7-21 parts of carbon black, 1-8 parts of stearic acid, 2-18 parts of octyl oleate, 1-9 parts of magnesium salt whisker, N 2-12 parts of tert-butyl-2-benzothiazole sulfonamide, 0.08-0.23 parts of silane coupling agent, 1-3 parts of protective wax, 0.1-1.9 parts of leveling agent, the crystals of the magnesium salt whiskers The whisker diameter is less than 1 μm, the alkali-free glass fiber is chopped fiber, and the leveling agent includes the following raw materials in parts by weight: 30-40 parts of sodium urealate polymer, 12-15 parts of hexamethylenetetramine, Sodium chloride 1.8-2.5 parts. The above-mentioned raw materials are kneaded and heated to form new tire materials, and the Acron wear is between 0.18-0.24cm3, achieving the effect of improving wear resistance.

Description

technical field [0001] The invention belongs to the technical field of new materials, and in particular relates to a new material for wear-resistant tires and a preparation method thereof. Background technique [0002] The outermost layer of the tire is in contact with the road surface and has a pattern printed on the surface. It can make the tire have traction, buffer the impact and swing when driving, and prevent the cord layer from being cut and pierced. It is required to have high wear resistance, fatigue resistance, good aging resistance, high tensile strength, elasticity and toughness, and low heat generation during driving. [0003] The Chinese patent application number 201410145691.4 discloses a tire tread rubber composition and a preparation method thereof, including N234 carbon black, octyl soap salt and natural rubber, wherein the mass ratio of N234 carbon black: octyl soap salt: natural rubber is 40~60:1~5:100, the resulting rubber has high strength and tear ...
