Abstract

Relating to the field of wire and cable materials, the invention provides a wire and cable material for electric power lines and a preparation method thereof. The wire and cable material for electric power lines comprises the following raw materials by weight: phenolic resin, acetal resin, polyamide resin, polyurethane rubber, ceramic fiber, calcium carbonate, aluminum silicate, silicon carbide, polyethylene wax, toner, a plasticizer, a flame retardant, an antioxidant, a curing agent, a light stabilizer and a heat stabilizer. The preparation method comprises the steps of: (1) weighing of the raw materials, (2) stirring, (3) mixing, (4) extrusion, and (5) grain dicing, cooling and packaging. The wire and cable material provided by the invention solves the problems that existing high-temperature resistant electric wires and cables are relatively hard, and during use, under the action of bending and other external forces, an insulation layer cracks easily, a conductor breaks easily, the flame retardance is poor, and the safety performance is unsatisfactory.

Description

technical field [0001] The invention belongs to the field of wire and cable materials, and in particular relates to a wire and cable material used in power lines and a preparation method thereof. Background technique [0002] Wires and cables used under high temperature conditions, such as microwave ovens, air conditioners, power distribution rooms, wires inside TVs, wires for lamp holders, and wires for automobiles, because the wires are soft, they have good twisting and bending properties, and the insulation layer is easy to crack. The highest use conditions for general PVC materials are: the national standard is 90°C, the United States is 105°C, and Europe is 90°C. Above this temperature, PE cross-linking and EVA+PE cross-linking materials are generally used. The disadvantage of these materials is that they are very hard and wire and cable It is inconvenient to use, the wire and cable need to be irradiated after production, the irradiation cross-linking process is not eas...
