Abstract

The invention provides a silane crosslinking halogen-free flame retardant polyvinyl chloride cable material. The cable material is prepared from the following raw materials in parts by weight: 70-80 parts of polyvinyl chloride resin, 10-20 parts of acrylic acid grafted modified acrylic resin, 1-2 parts of acetate butyl, 1-3 parts of ethyl trifluoroacetate, 8-10 parts of zinc borate, 2-3 parts of molybdeni trioxidum, 1-2 parts of copper oxide, 10-12 parts of magnesium hydrate, 8-10 parts of ammonium polyphosphate, 6-10 parts of triethyl citrate, 4-5 parts of fumarate, 10-15 parts of TCEP fire-retardant plasticizer tri-beta-chloroethyl phosphate, 1-2 parts of calcium-zinc stabilizer, 1-2 parts of calaium strarate, 0.2-0.3 part of zinc stearate, 8-10 parts of light calcium carbonate, 3-5 parts of talcum powder, 8-10 parts of calcined clay, 3-4 parts of magnesium carbonate, 0.2-0.3 part of glass bead, 1-2 parts of carbon alcohol ester double 18, 1-2 parts of polyethylene wax, 0.2-0.5 part of lead sulphate tribasic, 20-30 parts of heavy calcium carbonate, 3-5 parts of barium stearate, 0.5-0.8 part of lead stearate dibasic, 0.5-1.0 part of ethenyl triethoxysilane, and 8-10 parts of modified filler. The cable material has a good mechanical property, is good in heat resistance and insulating property, and has the characteristics of good ageing property, high flame resistance and environment protection property and the like.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a silane crosslinked halogen-free flame-retardant 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 non-halogen low-smoke silane c...
