The invention discloses a flame-retardant tire tread rubber material which is prepared from the following raw materials in parts by weight: 60-80 parts of cis-1, 4-polyisoprene rubber, 1-5 parts of epoxidized cis-1, 4-polyisoprene rubber, 1-5 parts of an antioxidant and 1-5 parts of a lubricant. The rubber composition is prepared from the following components in parts by weight: 10 to 20 parts of 1, 4-polyisoprene rubber, 20 to 40 parts of chloroprene rubber, 20 to 40 parts of high specific surface white carbon black, 10 to 20 parts of titanium diboride whisker, 2 to 4 parts of bis-[3-(triethoxysilyl) propyl]-tetrasulfide, 10 to 15 parts of [3-[(hydroxymethyl) amino]-3-carbonyl propyl]-dimethyl phosphonate, 3 to 7 parts of basic magnesium aluminum carbonate, 3 to 5 parts of zinc oxide, 0.5 to 2 parts of magnesium oxide, 1 to 2 parts of sulfur and 0.5 to 1.5 parts of multifunctional vulcanizing agent. 1-3 parts of microcrystalline wax, 1.5-3.5 parts of stearic acid, 2-5 parts of an anti-aging agent and 1-3 parts of an accelerant. According to the present invention, the flame retardation performance of the tire is ensured, the wear resistance, the tear resistance, the cutting and chipping resistance are significantly enhanced, the heat generation is low, the service life of the produced tire is long, and the fireproof safety and the durability of the tire of the hazardous chemical substance transport vehicle or the fire fighting truck, the smelting operation vehicle and other professional vehicles can be substantially ensured.
