Abstract
The invention discloses a high-flame-retardance low-smoke halogen-free cable material and a preparation method thereof. The preparation method is mainly to mix component raw materials including an ethylene-vinyl acetate (EVA) copolymer, high-density polyethylene (HDPE), kaolin, fire retardant, ammonium polyphosphate, nano calcium carbonate powder, attapulgite, silane coupling agent, titanate, antioxygen, paraffin wax and cross-linking agent according to a certain weight part ratio to prepare the high-flame-retardance low-smoke halogen-free cable material. When the simple preparation method is used, the operation is convenient, the formula of component raw materials is reasonable, and the prepared cable material has high mechanical property, high temperature resistance and high flame retardance, and when combusting, generates little smoke and is nontoxic.
Description
Technical field
The present invention relates to a kind of high-flame-retardance low-smoke halogen-free 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.
