Technical Field
The invention mainly relates to the technical field of cable materials, in particular to a flame-retardant cable material.
Background
The cable is made of one or more mutually insulated conductors and an outer insulating protective layer, and the wire, the cable and the sheath for transmitting power or information from one place to another are made of plastic commonly called cable material, which comprises various varieties such as rubber, plastic, nylon and the like. The cable material production enterprises take cable production enterprises as users, and have the market of cable materials as long as the requirements of wires and cables are met. The wire and cable products almost need an insulating layer opening except bare wire products such as steel-cored aluminum stranded wires, electromagnetic wires and the like. However, with the frequent occurrence of electrical fire accidents, the fire retardant problem of the electric wire and cable is gradually drawing attention from countries around the world. When the cable is burnt, a large amount of toxic smog and corrosive gas are released, which hinders the safe evacuation and fire extinguishing work of people and causes the serious loss of lives and properties. The currently used cable has poor flame retardancy and is easy to cause fire when being used for manufacturing electric wires and cables.
