Wire and cable material for telecommunication engineering and preparation method thereof

Abstract

The invention discloses a wire and cable material for telecommunication engineering and relates to the field of cable materials. The wire and cable material for telecommunication engineering comprisesthe following raw materials (by weight): 50-60 parts of VC resin, 20-30 parts of EPDM rubber, 8-15 parts of epoxy resin, 12-18 parts of modified montmorillonite powder, 8-15 parts of diatomite, 10-16parts of glass fiber, 12-18 parts of polyacrylonitrile fiber, 14-20 parts of light calcium carbonate, 4-9 parts of nickel oxide, 5-10 of nano-zinc oxide, 4-9 parts of nano-boron nitride, 3-7 parts oftitanium dioxide, 3-7 parts of carbon black, etc. Through synergism of the raw materials, the cable material of the invention has advantages of high strength, heat and weather resistance, corrosion resistance and ageing resistance, and has excellent tensile strength and fracture resistance. The raw materials contain no halogen elements, and no smokeless or harmful gas is generated during combustion. The wire and cable material of the invention is green and environmentally friendly.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a wire and cable material for telecommunication engineering and a preparation method thereof. Background technique [0002] Wire and cable is a wire product used to transmit electric (magnetic) energy, information and realize electromagnetic energy conversion. As the main carrier of power transmission, wire and cable are widely used in power engineering. [0003] A large amount of smoke and toxic and corrosive gases released when the existing wires and cables are burned are dangerous factors in fires, which hinder people's safe evacuation and fire fighting work in fires, causing serious losses to lives and property. With the development of communications industry, automobile industry and computer industry, especially in many occasions such as aviation wires, automobile wires, high temperature instrument cables, oil drilling platform cables, etc., it is increasingly necessary to us...

Problems solved by technology

[0003] A large amount of smoke and toxic and corrosive gases released when the existing wires and cables are burned are dangerous factors in fires, which hinder people's safe evacuation and fire fighting work in fires, causing serious losses to lives and property. With the development of communications industry, automobile industry and computer industry, especially in many occasions such as aviation wires, automobile wires, high temperature instrument cables, oil drilling platform cables, etc., it is increasingly necessary to use flame retardant, good thermal stability, and high heat distortion temperature. Wire and cable materials

[0004] In addition, the existing wire and cable materials used in electric power engineering still have the problems of low strength, poor toughness and easy aging
