Abstract

The invention discloses a low-smoke halogen-free fire resistant cable material and preparation method thereof, wherein the low-smoke halogen-free fire resistant cable material is prepared by the following step: mixing the composite raw materials ethylene-vinyl acetate copolymer EVA, high density polyethylene HDPE, melamine, zinc borate, roasted zeolite powder, attapulgite, nano calcium carbonate powder, silane coupling agent, 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 [0001] The invention relates to a low-smoke halogen-free flame-retardant cable material and a preparation method thereof, and belongs to the field of cables. Background technique [0002] With the rapid economic development, wires and cables have been 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. The large amount of smoke and toxic and corrosive gas released when the cable burns is a risk factor in the fire, which hinders the safe evacuation and fire fighting of people during the fire, and causes serious loss of life and property. At the same time, with the development of the communications industry, the automobile industry and the computer industry, especially in many occasions such as aviation wires, automotive wires, high-temperature instrument cables, and oil rig cables, it is increas...
