The invention discloses engineering tire tread rubber with high wear resistance and high tear resistance and a preparation method of the engineering tire tread rubber, and belongs to the technical field of mining engineering mechanical tire tread rubber. The technical scheme of the invention is as follows. Comprising the following components in parts by weight: 100 parts of a rubber component, 40-60 parts of carbon black, 3-5 parts of a rubber extension agent ZJ-990, 2-3 parts of alkylphenol tackifying resin or p-tert-octyl phenol formaldehyde tackifying resin, 3-5 parts of a rubber tear modifier KS-900, 3-5 parts of p-phenylenediamine and ketoamine anti-aging agents, 1-2 parts of microcrystalline wax, 3-5 parts of zinc oxide, 1-2 parts of stearic acid, 1.4-2.4 parts of sulfur and 1.0-2.0 parts of an accelerant. The wear resistance and the damage resistance of the tread rubber can be remarkably improved, and the problem that the service life of a product is short due to the fact that the tread rubber is not wear-resistant and easy to tear is solved, so that the longer service life of the product is provided, the mining efficiency is improved, and higher value is brought to customers.
