Abstract

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.

Description

technical field [0001] The invention relates to a 105°C thermoplastic halogen-free, low-smoke, flame-retardant, ultraviolet-proof, rodent-proof, anti-cracking type cable sheath material and a preparation method thereof, belonging to the technical field of materials for electric wires and cables. Background technique [0002] Rats and termites are rampant in most areas of our country and damage cables. If the cables used as the "arteries" and "nerves" of the power supply system are bitten by rats and ants, it will not only cause serious power failures and information confusion, but even It may cause a large-scale short circuit and cause a fire, etc. [0003] In addition, the biggest problem of halogen-free flame-retardant cables is sheath cracking, which often occurs on the cable reel, and is usually a large-size cable on the outermost sunny side of the reel. The probability of occurrence in summer is higher than that in winter. high. In order to solve the anti-cracking pro...
