A kind of matte flame-retardant polyvinyl chloride wire and cable material and preparation method thereof

Abstract

The invention provides a fog-face fire-retardant polyvinyl chloride electric wire and cable material prepared from the following raw materials in parts by weight: 60-80 parts of polyvinyl chloride, 15-20 parts of an organosilicone modified thermoplastic phenolic resin, 1-2 parts of calcium silicate, 8-10 parts of wood flour, 40-50 parts of calcium carbonate, 40-50 parts of epoxidized triethylhexanoin, 4-5 parts of palm oil, 4-10 parts of methyl laurate, 20-30 parts of magnesium hydroxide, 3-5 parts of decabromodiphenyl ethane, 1.0-2.0 parts of ammonium molybdate, 3-7 parts of a stabilizer, 0.5-1.5 parts of microcrystalline wax, 1-2 parts of sodium selenite, 8-10 parts of aluminium hypophosphite, 1-2 parts of ammonium polyphosphate, 1-2 parts of alcohol ester-12, and 8-10 parts of a modified filler. The fog-face fire-retardant polyvinyl chloride electric wire and cable material has the characteristics of flame retardancy, oil resistance, aging resistance, and acid and alkali resistance, and has lower specific density and low cost.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a matte flame-retardant polyvinyl chloride wire and cable material and a preparation method thereof. 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 aluminum hydroxide to polyolefin substrates to achieve flame-retar...

Problems solved by technology

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 aluminum hydroxide to polyolefin substrates to achieve flame-retardant effects. However, The addition of a large number 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.
