Wear-resistant natural rubber flame-retardant sole rubber and preparation method thereof

The wear-resistant natural rubber flame-retardant sole rubber is prepared from natural rubber, synthetic rubber, sulfur, an accelerant, a vulcanizing activator, a release agent, carbon black, a softening agent, a composite flame retardant and an anti-aging agent. Natural rubber and butadiene rubber are used as main materials, N220wt is added as a reinforcing agent and a softening agent to ensure the physical properties of the rubber material and ensure the service life of the rubber sole, and the composite flame retardant is adopted as a synergistic flame-retardant system to provide excellent flame-retardant property for the product; according to the present invention, by adding the flame retardant, the carbon layer is generated during the combustion so as to adsorb the molten and on-fire polymer, the fire hazard caused by the droplet transfer can be prevented, the disadvantage that the conventional NR + SBR + BR rubber compound is easily combusted is overcome, the disadvantage that the chloroprene rubber is
