Abstract

The invention provides a heat-resistant wire and cable material used in an electric power line and a preparation method thereof and relates to the field of wire and cable materials. The heat-resistant wire and cable material used in the electric power line is prepared from, by weight, polyvinyl chloride, chloroprene rubber CR121, dimethyl silicone oil, polypropylene fiber, chlorinated polyethylene, nano silicon carbide, heavy calcium carbonate powder, nano active calcium carbonate, trioctyl trimellitate, a Congo red invariant-color calcium zinc stabilizer, a heat-resistant invariant-color calcium-zinc stabilizer, kaolin, PE wax, stearic acid, a flame retardant, an antioxidant, a coupling agent and a plasticizer. The preparation method comprises the following steps of raw material weighing, mixing and granulation. The problems of poor heat resistance, poor flame retardancy, poor toughness and low strength of existing wire and cable materials are solved.

Description

technical field [0001] The invention belongs to the field of wire and cable materials, and in particular relates to a heat-resistant wire and cable material used in power lines and a preparation method thereof. Background technique [0002] In recent years, with the increasing development and popularization of the use of wires and cables in production and life, the demand for wires and cables has increased rapidly, and with the development of the economy, the requirements for its materials have become higher and higher. [0003] In the power line, some power cords or connecting wires for electrical appliances require high temperature resistance, but the existing wire and cable materials generally have the problem of poor heat resistance, which can easily lead to softening of the wire and cable materials, seriously affecting the normal use of equipment and service life. In addition, the existing wire and cable materials still have the problems of poor flame retardancy, poor ...
