Problems solved by technology

Fire accidents caused by the burning of plastic cable insulation will cause incalculable losses to society and families. Existing cable insulation is mostly added with halogen-containing flame retardants. However, when halogen-containing flame-retardant materials burn It will release a lot of smoke and toxic, corrosive hydrogen halide and other gases, which will hinder people from evacuating from the fire and fire fighting work. Therefore, the development of low-smoke, halogen-free flame-retardant technology has become a hot issue in the world.

Abstract

The invention discloses a red phosphorus-containing cable insulation layer which is prepared from the following components: basic resin, red phosphorus, ammonium polyphosphate, organic montmorillonite, an antioxidant and a modifier, wherein the basic resin is prepared from an ethylene-ethylene vinlacetate copolymer, a hydrogenated styrene-butadiene segmented copolymer and polyethylene; the antioxidant is 4,4'-sulfo-dis(6-tertiary butyl-3-methylphenol); and the modifier is pentaerythritol. The cable insulation layer disclosed by the invention does not contain halogen and is excellent in flame retardant effect.

Description

technical field [0001] The invention relates to a cable insulating layer, in particular to a cable insulating layer containing red phosphorus. 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. Fire accidents caused by the burning of plastic cable insulation will cause incalculable losses to society and families. Existing cable insulation is mostly added with halogen-containing flame retardants. However, when halogen-containing flame-retardant materials burn It will release a lot of smoke and toxic and corrosive hydrogen halide and other gases, which will hinder people from evacuating from the fire and fire fighting work. Therefore, the development of low-smoke halogen-free flame-retardant technology has become a hot issue in...
