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.

The present invention relates to a kind of 105 DEG C of thermoplastic halogen-free and low-smoke flame-retardant UV resistant rat-and-ant proof cracking resistant type cable jacket materials and preparation method thereof, belong to electric wire and use material technology field.
Background technology
All there is mouse, termite activity wildness, destroy the phenomenon of cable in China most areas, as the cable of power supply system " artery " and " nerve ", if bitten by mouse, ant, not only can cause serious power failure and information confusion, even can cause extensive short circuit initiation fire etc.
In addition the greatest problem that halogen-free flame-retardant cable exists is exactly sheath cracking, will occur on hank of cable toward contact, and the large specification cable of the outermost layer sunny slope of drum normally, summer, the likelihood ratio probability of occurrence in winter of generation was high.For solving the problem of cable rat-and-ant proof cracking resistance, before this, many people have done a large amount of research trials, but fail so far to deal with problems well.
Summary of the invention
Object of the present invention is that the destruction of rat-and-ant proof solves the problems such as halogen-free flame-retardant sheath is easy to crack simultaneously, and a kind of 105 DEG C of thermoplastic halogen-free and low-smoke flame-retardant UV resistant rat-and-ant proof cracking resistant type sheath materials and preparation method thereof are provided.
Think that after deliberation cable sheath cracking is stressed with cable bend and be heated relevant.The solution thinking of anti-cracking performance should be set about from these two angles.Adopt and add the agent of environment protection, rat ant.Such environment protection mouse-proof ant agent belongs to third generation product, obviously sharp flavor, long half time of environmental protection, low toxicity, nothing.Can effectively protect cable.The rare copolymerization thermoplastic elastomer of ethene-Xin and high density polyethylene(HDPE) in binder resin, are added simultaneously.In its molecular structure of the rare copolymer elastomer of ethene-Xin, there is no unsaturated double-bond, there is excellent ageing-resistant performance; Secondly its narrow molecular weight distribution, has good mobility, can play the effect that disperses buffering while making system be subject to impact, reduces because of the stressed probability cracking.Its degree of crystallinity of high density polyethylene(HDPE) and fusing point are all relatively high, have good rigidity and toughness simultaneously, just can reach higher temperature resistant grade (105 DEG C) without crosslinked, improve system hardness simultaneously, play certain physics anti-rat.
Grade (105 DEG C) improves system hardness simultaneously, plays certain physics anti-rat.With respect to thermoset sheath, adopt thermoplastic sheath to there is the raw materials cost of reduction, simplify production technique, enhance productivity, material can cycling and reutilization etc. outstanding advantages.
