Green and flame-retardant cable filler

Abstract

Provided is a green and flame-retardant cable filler. The green and flame-retardant cable filler is prepared from the following raw materials, by weight, 16-32 parts of acrylic acid ester rubber microballoons, 8-14 parts of hydroquinone, 4-7 parts of zinc oxide, 5-8 parts of environmental protection thermal stabilizing agent, 6-17 parts of filling agent, 10-20 parts of magnesium hydroxide, 0.8-1.6 parts of AC foaming agent, 3-6 parts of magnesium stearate, 12-22 parts of nano graphene, 8-15 parts of graphite, 3-4 parts of oxidized polyethlene wax, 0.8-2.4 parts of curing accelerator, 6-13 parts of potassium nitrate, 4-7 parts of calcium stearate, 6-10 parts of sodium nitrite, 7-12 parts of sodium salicylate, and 5-8 parts of potassium sulfate. The beneficial effects are that the green and flame-retardant cable filler is advantaged by good flame retardant effects, high temperature resistance, low smoke, no generation of toxic substances, green and environmental protection.

Description

technical field [0001] The invention relates to a green flame-retardant cable filler. 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. When an accident occurs or spontan...
