Description

A kind of wear-resisting non-halogen flame-retardant cable and preparation method thereof
Technical field
The present invention relates to CABLE MATERIALS field, particularly relate to a kind of wear-resisting non-halogen flame-retardant cable and preparation method thereof.
Background technology
Wire cable insulating and sheath plastics are commonly called as CABLE MATERIALS, which includes the multiple product such as rubber, plastics, nylon Kind.Along with the development of society, electric wire is increasingly widely used in every field, as transported, communicating, building etc., because of This, the requirement to the professional field of electric wire is more and more higher, cable typically in laid processes main by ambient pressure, draw Power, bend, collide, the effect of beating etc., and CABLE MATERIALS in use can stand cold and hot, light, chemicals, water, voltage Test Deng environment, it may appear that scuffing, corrosion, wear, fracture, ftracture, aging, burn, puncture the phenomenons such as electric leakage, need to improve The performance of CABLE MATERIALS.
Low-smoke halogen-free flame-retardant polyolefin cable protective cover material in actual applications, often faces mechanical property, processing characteristics and resistance The problem mutually restricted between combustion performance and can not take into account.For obtaining optimal mechanics on the basis of meeting Essential Performance Requirements Performance and the balance of fire resistance, conventional means have: inorganic fire-retarded filler surface coupling processing, use bulking agent etc., this kind Method can not be fully solved the binding ability of inorganic fire-retarded filler and plastics.Other fillers also can deposit same consistency problem, Need to improve technique to improve the mechanical property of CABLE MATERIALS.
Summary of the invention
It is an object of the invention to provide a kind of wear-resisting non-halogen flame-retardant cable, the wearability of this CABLE MATERIALS, good flame resistance, And poison will not be decomposited.
Technical scheme is as follows:
A kind of wear-resisting non-halogen flame-retardant cable, it is characterised in that be prepared by the raw materials in: white carbon black 8-9, redispersible Latex powder 0.6-0.8, nanmeter antimong trioxide 2-2.5, magnesium hydroxide 2-3, aluminium hydroxide 6-7, polyacrylonitrile 9-10, polylactic acid 6-7, polyethylene glycol oxide 3-4, dimethylformamide are appropriate, dimethylformamide/dichloromethane volume ratio is that 1:1 double solvents is fitted Measure, methyl methacrylate is appropriate, isopropyl thioxanthone is appropriate, ethylene-vinyl acetate copolymer 20-25, low density polyethylene Alkene 80-85.
The production method of described wear-resisting non-halogen flame-retardant cable, it is characterised in that:
(1) polyacrylonitrile is dissolved in dimethylformamide, makes the solution of 11-12wt%, polylactic acid is dissolved in dimethyl formyl Amine/methylene chloride volume, than for 1:1 double solvents, makes the solution of 11-12wt%, polyethylene glycol oxide be dissolved in dimethylformamide/ Methylene chloride volume, than for 1:1 double solvents, is made the solution of 11-12wt%, then it is molten that three kinds of solution are mixed to get polymer Liquid；
(2) by the isopropyl thioxanthone relative to polyacrylonitrile content 14-16wt% and the methyl of 14-16wt% in darkroom Acrylic acid methyl ester. adds in polymer solution, stirs to after being completely dissolved, adds white carbon black, redispersable latex powder, nanometer three oxygen Changing two antimony, stir, stand 20-30 minute, add magnesium hydroxide, aluminium hydroxide, stir, ultrasonic disperse 4-5 divides Clock, obtains spinning liquid；
(3) spinning liquid (2nd) step obtained carries out electrostatic spinning, then drying under ultraviolet light irradiates, and obtains fiber；
(4) (3rd) fiber obtained is mixed with other residual componentss, send in high-speed mixer and mix, 110-120 DEG C Lower mix homogeneously, then through pelletize and get final product.
Beneficial effects of the present invention
CABLE MATERIALS of the present invention, by using white carbon black, improves the wearability of CABLE MATERIALS；By add aluminium hydroxide, magnesium hydroxide, Nanmeter antimong trioxide, has cooperative flame retardant effect, substantially increases the anti-flammability of CABLE MATERIALS, and will not decomposite poison； Present invention process solves filler, and to assemble pockets of phenomenon because dispersion is uneven obvious so that filler distribution uniformly and is covered by In matrix resin, beneficially filler and the interface cohesion of matrix resin, and also the fiber formed greatly improves the mechanics of CABLE MATERIALS Performance, improves the performances such as tear-resistant, toughness；By adding redispersable latex powder, improve the caking property of filler and fiber, Improve the toughness of CABLE MATERIALS.
