Description

A kind of useless china powder strengthens CABLE MATERIALS and preparation method thereof
Technical field
The present invention relates to CABLE MATERIALS field, particularly relate to a kind of useless china powder and strengthen CABLE MATERIALS 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 useless china powder and strengthen CABLE MATERIALS, the thermostability of this CABLE MATERIALS, wearability, resistance to Breakdown performance, processing characteristics, good flame resistance.
Technical scheme is as follows:
A kind of useless china powder strengthens CABLE MATERIALS, it is characterised in that be prepared by the raw materials in: silicone powder 5-6, useless china Powder 6-8, sulfur 1.4-1.8, antimony oxide 6-7, polyacrylonitrile 9-10, polylactic acid 6-7, polyethylene glycol oxide 3-4, dimethyl methyl Amide is appropriate, dimethylformamide/dichloromethane volume ratio is that 1:1 double solvents is appropriate, methyl methacrylate appropriate, isopropyl Base thioxanthone is appropriate, ethylene-vinyl acetate copolymer 20-25, Low Density Polyethylene 80-85.
Described useless china powder strengthens the production method of CABLE MATERIALS, it is characterised in that:
