A low-smoke environment-friendly cable material

Abstract

The invention provides a low-smoke environmental-friendly cable material, which is prepared from the following raw materials in parts by weight: 60-70 parts of ethane-vinyl acetate copolymer (EVA), 20-30 parts of high-density polyethylene (HDPE), 10-15 parts of low-density polyethylene, 5-10 parts of bisphenol A polycarbonate, 5-8 parts of compatilizer, 2-3 parts of ammonium molybdate, 1-2 parts of copper oxide, 15-20 parts of magnesium hydroxide, 5-8 parts of ammonium polyphosphate, 10-15 parts of roasted argil, 1-2 parts of mercaptan octyl tin, 2-4 parts of glycerol monostearate, 1-2 parts of chlorinated paraffin, 0.5-0.8 part of antioxidant 1010, 0.6-0.9 part of antioxidant 168, 0.2-0.8 part of N, N'-ethylene bis stearamide, 0.2-0.5 part of liquid paraffin and 10-12 parts of modification filler. The preparation method of the low-smoke environmental-friendly cable material is simple and convenient to operate, the constituent raw materials are formulated rationally, and the prepared cable material has high mechanical property and flame resistance, is high temperature resistant, and is low-smoke and nontoxic when burning.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a low-smoke and environment-friendly cable material. Background technique [0002] With the rapid development of the global economy and the enhancement of human awareness of environmental protection, the requirements for the quality and performance of wires and cables in various fields are getting higher and higher, and there are more and more fires caused by the aging of wires and cables. How to reduce the fire Low smoke, halogen-free, flame retardant, and environmental protection have also become the development direction of the wire and cable industry. Among them, the demand for halogen-free low-smoke flame-retardant cable materials is increasing. At present, most of the production of halogen-free low-smoke flame-retardant cable materials is to add a large amount of magnesium hydroxide or magnesium hydroxide to polyolefin substrates to achieve flame retardancy. However, the add...

Among them, the demand for halogen-free low-smoke flame-retardant cable materials is increasing. At present, most of the production of halogen-free low-smoke flame-retardant cable materials is to add a large amount of magnesium hydroxide or magnesium hydroxide to polyolefin substrates to achieve flame retardancy. However, the addition of a large amount of inorganic materials affects the physical and mechanical properties and processing performance of the cable material. Its softness, poor weather resistance, oil resistance, and low temperature resistance at room temperature are not very good.
