Environment-friendly flame-retardant filler for cables

Abstract

The invention relates to an environment-friendly flame-retardant filler for cables, which is prepared from the following raw materials in parts by weight: 12-22 parts of reactive diluent glycidol ether, 6-12 parts of PN-40, 20-32 parts of butyl rubber particle, 25-36 parts of polyvinyl chloride resin, 4-6 parts of anti-aging agent, 7-13 parts of flame retardant, 8-11 parts of PE (polyethylene) powder, 5-10 parts of plasticizer, 12-23 parts of silane-PC (polycarbonate) resin copolymer, 4-6 parts of antioxidant, 15-18 parts of nano calcium carbonate, 10-16 parts of SBS (styrene-butadiene-styrene) resin copolymer, 2-4 parts of paraffin oil, 1-3 parts of sodium sulfite, 8-13 parts of diatomite, 6-9 parts of glass fiber, 10-16 parts of magnesium hydroxide and 4-10 parts of silica. The flame-retardant filler for cables has favorable flame-retardant effect and favorable strength, can not generate toxic substances, and enhances the strength of the cable.

Description

technical field [0001] The invention relates to an environment-friendly flame-retardant filling material for cables. Background technique [0002] With the rapid development of my country's economy, wires and cables have played a very important role in the infrastructure construction of our country. In the cable production process, in order to ensure the roundness of the cable and avoid the mutual friction between the core wires, it is necessary to add filling materials between the core wires. The PVC flame retardant filling strip is mainly halogen flame retardant. , will produce a large amount of smoke, and produce toxic, irritating and corrosive hydrogen halide gas; smoke will hinder fire fighting and personnel evacuation, hydrogen halide gas will corrode equipment, and endanger human health. With the enhancement of human awareness of environmental protection, the quality and performance requirements of wires and cables in various fields are getting higher and higher. Whe...
