The invention discloses a wear-resistant flame-retardant sole rubber for forest fire-fighting shoes. According to the present invention, natural rubber, butadiene-styrene rubber and cis-1,4-polybutadiene rubber are used as main materials, the physical properties of the rubber material are ensured by adding a reinforcing filler and a softener, the service life of the rubber sole is ensured, and theexcellent flame retardancy is provided for the product by adopting efficient flame retardants decabromodiphenyl ether, chlorinated paraffin, zinc borate and antimony oxide as a flame retardant system; a carbon layer is generated during combustion so as to adsorb molten and ignited polymers, liquid drops can be prevented from transferring fire disaster, the defect that the conventional NR+SBR+BR rubber compound is extremely easily combusted is overcome, the flame retardant level can reach the UL94V-0 level, and the self-extinguishing requirement is met in a vertical combustion test; and the product has characteristics of simple preparation method, low cost and good use effect, and can completely meet the use requirements of forest firefighters.
