Abstract

The invention relates to cutting-resistant, chunking-resistant and chipping-resistant all-steel engineering radial tire tread rubber and a preparation method thereof. The cutting-resistant, chunking-resistant and chipping-resistant all-steel engineering radial tire tread rubber comprises the following components in parts by weight: 20-30 parts of natural rubber, 70-80 parts of butadiene styrene rubber, 55-60 parts of carbon black, 5-15 parts of white carbon black, 1-3 parts of stearic acid, 3-5 parts of zinc oxide, 5-6 parts of an anti-aging system, 2-4 parts of resin, 3-6 parts of oil and 2-4 parts of a vulcanization accelerator. Compared with the prior art, the cutting resistance of the tread rubber is improved by adopting high parts of butadiene styrene rubber, and meanwhile, the heat generation performance of the rubber material is reduced by adopting a variety of carbon black for use, so that the service life of the engineering tire is prolonged.

Description

technical field [0001] The invention relates to the technical field of tire rubber, in particular to an all-steel engineering radial tire tread rubber that is resistant to cutting and anti-collapse, and a preparation method thereof. Background technique [0002] In 1946, the French Michelin company invented the radial tire, which brought revolutionary changes to the tire industry. Subsequently, this technology was extended to various types of tires, and the world's first radial tire was manufactured in 1959. The advent of radial tires has shown incomparable advantages compared with bias tires. Therefore, radial tires developed the earliest and fastest in Western Europe. France was almost 100% meridian as early as 1972, and by the end of 1989 the Western European tire market was 100% meridian. [0003] All-steel engineering radial tires have the properties of fuel saving, low heat generation, high mileage, large load capacity, good wear resistance, cutting resistance, punc...
