The invention relates to an all-steel load radial tire tread base rubber material and a preparation method thereof. The base rubber material comprises the following raw materials in parts by weight: 100 parts of natural rubber, 0-0.3 part of a peptizer, 30-45 parts of carbon black, 7-18 parts of white carbon black, 1-4 parts of a silane coupling agent, 3-5 parts of zinc oxide, 1-3 parts of stearic acid, 1-3 parts of phenolic tackifying resin, 0.5-3 parts of petroleum resin, 0.5-2 parts of an anti-aging agent 6PPD, 0.5-2 parts of an anti-aging agent RD, 1-3 parts of sulfur, 0.8-3 parts of an accelerator and 0-0.3 part of a scorch retarder. Petroleum resin is added to improve the medium-term and long-term viscidity of a tire tread half member so that the tread is well bonded with belt layers during molding and the phenomenon of delamination of a tread crown is improved. The material disclosed by the invention has the advantages of good thermal resistance and aging resistance, low heat generation and tear resistance and the problem of pattern groove cracking of the finished tread is improved.
