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 convenientto 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 materialis burned, it is low in smoke and is non-toxic.

Description

technical field [0001] The invention relates to a low-smoke halogen-free polyolefin cable material and a preparation method thereof, belonging to the field of cables. Background technique [0002] With the rapid development of the economy, wires and cables are widely used in various industries and fields. With the frequent occurrence of electrical fire accidents, the flame retardant problem of wires and cables has gradually attracted the attention of countries all over the world. When the cable burns, it releases a large amount of smoke and toxic and corrosive gas, which is a risk factor in a fire. It hinders people's safe evacuation and fire fighting work during a fire, causing serious loss of life and property. At the same time, with the development of the communication industry, the automobile industry and the computer industry, especially in many occasions such as aviation wires, automobile wires, high-temperature instrument cables, and oil drilling platform cables, it ...
