A Halogen-free Flame-Retardant Environment-friendly XLPE Cable Material

Abstract

The invention provides a halogen-free flame-retardant environment-friendly crosslinking polyvinyl chloride cable material. The material is composed of the following components by weight: 80-90 parts of polyvinyl chloride resin, 10-15 parts of polyethylene resin, 5-8 parts of epoxy organic acid calcium, 8-10 parts of zinc stearate, 8-10 parts of stearic acid, 1-2 parts of powder paraffin, 4-5 parts of semi-refined paraffin wax, 2-4 parts of phosphite ester, 3-4 parts of pentaerythritol ester, 8-10 parts of zeolite powder, 1-2 parts of calcium stearate, 8-10 parts of light calcium carbonate, 8-10 parts of diatomite, 6-8 parts of barium sulfate, 8-10 parts of perlite, 8-10 parts of aluminum hydroxide, 1-2 parts of talcum powder, 1-2 parts of alumina, 0.2-0.3 part of zirconium oxide, 10-15 parts of triethyl citrate, 3-5 parts of a plasticizer butyl ester DBP, 3-5 parts of epoxy butyl oleate, 2-4 parts of oleic butyl epoxy stearate, 6-8 parts of zinc borate, 10-12 parts of decabromodiphenylethane, 3-5 parts of molybdenum trioxide and 1-2 parts of a crosslinking agent DOC. The halogen-free flame-retardant environment-friendly crosslinking polyvinyl chloride cable material produced by the method provided by the invention has the advantages of environmental protection, good flame retardant performance, high temperature resistance, low smoke, good compatibility and good shaping; and the produced cable material has stable quality.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a halogen-free flame-retardant and environment-friendly cross-linked polyvinyl chloride cable material. Background technique [0002] Wire and cable are indispensable and important materials in industrial and agricultural production and modern life. my country is the world's largest producer of wire and cable. The wire and cable industry occupies a very important position in my country's national economy. However, at present, the market The cable material is not resistant to high temperature and aging, and the material turns yellow and becomes brittle after the aging test. There are more and more fires caused by aging wires. How to reduce the incidence of fire and the death rate in the event of 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-fre...

Problems solved by technology

Among them, the demand for halogen-free, low-smoke, halogen-free, flame-retardant and environmentally friendly cross-linked polyvinyl chloride cable materials is increasing. A large amount of acetylene carbon black or acetylene carbon black is added to the material to achieve the flame retardant effect. However, the addition of a large amount of inorganic materials affects the physical and mechanical properties and processing of the cable material.
