Abstract

The invention discloses a mine tire and a preparation method thereof. The invention is characterized in that the mine tire is prepared from the following raw materials in percentage by weight by a Banbury mixer: 35-60% of emulsion-polymerized butadiene-styrene rubber, 0-15% of natural rubber, 1-4% of activator zinc oxide, 25-38% of medium / super-wear-resistance carbon black, 0.2-2.0% of anti-aging agent RD, 0.2-2.0% of anti-aging agent IPPD, 0.3-1.0% of stearic acid, 0.3-1.2% of protective wax, 0.3-1.1% of paraffin, 1-5% of tackifying resin, 1.5-6% of aramid fiber pulp short fiber, 1-5% of aromatic oil, 0.5-1.5% of dispersing agent FS-97, 0.5-2% of sulfur, 0.5-2.5% of accelerator NS and 0.05-0.3% of anti-scorching agent. The tire tread has the advantages of high hardness, high tensile strength and excellent rubber tear resistance, is capable of effectively reducing the phenomenon of loosening of tread plug and enhancing the service performance and traveling safety of the mine tire, and prolongs the service life of the tire.

Description

Technical field: [0001] The invention relates to the technical field of tires, in particular to a mining tire formula and a preparation method thereof. Background technique: [0002] As we all know, the conditions of the mining area are extremely harsh. The road surface is covered with sharp gravel, and some roads still have water. When tires are used under such conditions, tires often burst due to pattern cuts, block drops, and even punctured treads. Phenomenon, reduce the service life of tires, and even lead to traffic accidents in severe cases, endangering life safety. Invention content: [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art, and provide a kind of mining tire formula. [0004] Another object of the present invention is to provide a preparation method of the mine tire formula. [0005] The invention mainly solves the problems that existing tires are easily damaged and endanger safety when used in ...
