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 material and preparation method thereof, belong to field of cables.
Background technology
Along with developing rapidly of economy, electric wire all is widely used in industry-by-industry, field.Along with the frequent occurrence of electrical fire accident, the fire-retardant problem of electric wire causes the attention of countries in the world gradually.Discharging a large amount of smog and poisonous, corrosive gas during cable fire is Hazard Factor in the fire, has hindered people's safe escape and fire-fighting work in fire, makes 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 wire, line for cars, high temperature instrument cable, oil drilling platform cable more and more need to use 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 material and preparation method thereof, CABLE MATERIALS of the present invention has that mechanical property is high, high temperature resistant, flame retardant properties is high, LSZH during burning.
The following technical scheme of employing of the present invention for achieving the above object:
PVC cable material is characterized in that the weight part of its constitutive material is:
Described PVC cable material is characterized in that: described fire retardant is selected from a kind of or mixture in aluminium hydroxide and the magnesium hydroxide.
Described PVC cable material is characterized in that: described oxidation inhibitor is selected from 020 copper inhibitor, and lubricant is selected from paraffin, and linking agent is selected from trimethylolpropane trimethacrylate.
The preparation method of described PVC cable material is characterized in that may further comprise the steps:
(1) weight part by constitutive material takes by weighing each raw material, and ethylene-vinyl acetate copolymer EVA, high density polyethylene, methyl triacetoxysilane, part roasting zeolite powder and nano-calcium carbonate calcium powder are mixed, and obtains compound A;
(2) add by weight fire retardant, zinc borate, silane coupling agent, stalk ashes, titanic acid ester, oxidation inhibitor, lubricant and linking agent among the compound A in above-mentioned steps (1), under the normal temperature stirring at low speed 1-2 minute, so that mix, obtain compound B;
(3) the compound B that above-mentioned steps (2) is obtained adds mill and Banbury mixer or twin screw extruder is mixing, granulation, and 140-170 ℃ of control temperature obtains finished product.
Beneficial effect of the present invention:
Preparation method of the present invention is simple, and is easy to operate, and the constitutive material prescription is reasonable, and the CABLE MATERIALS that makes has that mechanical property is high, high temperature resistant, flame retardant properties is high, LSZH during burning.
