A halogen-free environment-friendly flame-retardant polyolefin cable material containing polysiloxane

Abstract

The invention provides a halogen-free, environment-friendly and flame-retardant polyolefin cable material containing polysiloxane. The cable material is prepared from the following raw materials in parts by weight: 50-60 parts of ethylene vinyl acetate, 5-10 parts of polyester resin, 10-15 parts of novolac epoxy vinyl ester resin, 10-20 parts of aromatic polysiloxane, 5-6 parts of ammonium polyphosphate, 10-12 parts of decabromodiphenyl oxide, 5-10 parts of fire retardant TCEP, 8-10 parts of trioctyl phosphate, 8-10 parts of triethyl citrate, 4-6 parts of di-2-ethylhexyl maleate, 1-2 parts of carbon alcohol ester double 18, 1-2 parts of cross-linking agent TAIC, 1-2 parts of tetraisopropyl di(dioctylphosphate) titanate, 1-2 parts of distearoyl isopropoxy aluminate, 8-10 parts of glass powder, 4-6 parts of talcum powder, 1-2 parts of barium sulfate, 1-1.5 parts of titanium dioxide, 5-6 parts of cinerite, and 13-16 parts of modified filler. The cable material has a good flame retardant property, does not generate toxic gases, and is green and environment-friendly, the formula materials are good in compatibility, and the cable material is good in mechanical property, processability, insulativity, flexibility, low temperature resistance, weather resistance and other properties.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a polysiloxane-containing halogen-free environment-friendly flame-retardant polyolefin 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-free...

Problems solved by technology

Among them, the demand for halogen-free, low-smoke, polysiloxane-containing, halogen-free, environmentally friendly, and flame-retardant polyolefin cable materials is increasing. At present, the production of halogen-free, low-smoke, and polysiloxane-containing, halogen-free, and environmentally-friendly flame-retardant polyolefin cable materials Most of them add a large amount of acetylene carbon black or acetylene carbon black to the polyolefin substrate 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 cable materials.
