The invention provides a 105 DEG C thermoplastic, halogen-free, low-smoke, fire-retardant and ultraviolet-resistant covering material capable of preventing mice and ants and resisting cracking. The covering material comprises the following raw materials: an ethylene vinyl acetate copolymer, linear low density polyethylene, high density polyethylene, ethylene-octene copolymer elastomer, a maleic anhydride grafting material, silicone master batch, aluminium hydroxide, magnesium hydrate, zinc borate, a phosphorus-nitrogen type intumescent flame retardant, a silane coupling agent, a lubricating agent, a complex antioxidant, a light stabilizer, and an environment-friendly mice and ants preventing agent. The preparation method comprises the following steps: uniformly mixing the raw materials above through a high-speed mixer; and then extruding and granulating through a double-step single-screw reciprocating extruding unit to obtain the covering material. The covering material is scientific and reasonable in formula and matching, and advanced in process; the prepared 105 DEG C thermoplastic, halogen-free, low-smoke, fire-retardant and ultraviolet-resistant covering material capable of preventing mice and ants and resisting cracking is applicable to manufacture of cables, and the prepared cable is high in mechanical performance, flame retardant performance, electrical performance and low-temperature performance, outstanding in resistance to mice and ants, resistance to thermo-oxidative aging, and excellent in resistance to high-temperature cracking.
