Abstract
The invention discloses a low-smoke halogen-free polyolefin cable material and preparation method thereof, wherein the low-smoke halogen-free polyolefin cable material is prepared by the following step: mixing the composite raw materials ethylene-vinyl acetate copolymer EVA, high density polyethylene HDPE, PE fire retardant, zinc borate, roasted zeolite powder, nano calcium carbonate powder, silane coupling agent, attapulgite, acid esters, anti-oxidant, lubricating agent and coupling agent based on parts by weight proportioning. The preparation method of the invention is simple and convenient to operate. The formula of composite raw materials is rational. The prepared cable material has high mechanical properties and high fire resistance, and can resist high temperature. When the material is burned, it is low in smoke and is non-toxic.
Description
Technical field
The present invention relates to a kind of low-smoke halogen-free polyolefin 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 low-smoke halogen-free polyolefin 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:
Low-smoke halogen-free polyolefin cable material is characterized in that the weight part of its constitutive material is:
Described low-smoke halogen-free polyolefin cable material is characterized in that: described oxidation inhibitor is selected from antioxidant 1010, and lubricant is selected from paraffin, and linking agent is selected from peroxidation two alkane.
The preparation method of described low-smoke halogen-free polyolefin 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, part roasting zeolite powder and nano-calcium carbonate calcium powder are mixed, and obtains compound A;
(2) add by weight PE fire retardant, attapulgite, zinc borate, silane coupling agent, 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:
