Abstract
The invention discloses a PVC cable material and its preparation method. The PVC cable material is prepared mainly by mixing the following compositional materials in a certain ratio by weight: an ethylene-vinyl acetate copolymer (EVA), high density polyethylene (HDPE), methyltriacetoxysilane, a flame retardant, zinc borate, roasted zeolite powder, nano-calcium carbonate powder, a silane coupling agent, straw ash, titanate, an anti-oxidant, a lubricant and a cross-linking agent. The preparation method of the invention is characterized by simplicity, convenient operation, and reasonable compositional material formula. And the prepared cable material has the advantages of high mechanical performance, high temperature resistance, high flame resistance, as well as low smoke and nontoxicity during combustion.
Description
Technical field
The present invention relates to a kind of pvc CABLE MATERIALS and preparation method thereof, belong to field of cables.
Background technology
Along with rapid economic development, electric wire all is widely used in industry-by-industry, field.Along with the frequent generation of electrical fire accident, the fire-retardant problem of electric wire causes the attention of countries in the world gradually.Discharge a large amount of smog during cable fire and deleterious, corrosive gas is Hazard Factor in the fire, in fire, hindered people's safe escape and fire-fighting work, make lives and properties suffer heavy losses.While is along with the development of communication career, automotive industry and computer industry; Particularly many occasions such as aviation lead, line for cars, high temperature instrument cable, oil drilling platform cable more and more need be used low smoke no-halogen wire cable high temperature resistant, weather.
Summary of the invention
The purpose of this invention is to provide a kind of pvc CABLE MATERIALS and preparation method thereof, CABLE MATERIALS of the present invention have the mechanical property height, high temperature resistant, flame retardant properties is high, LSZH during burning.
For realizing the following technical scheme of above-mentioned purpose employing of the present invention:
The pvc CABLE MATERIALS is characterized in that the weight part of its constitutive material is:
