Abstract

The invention provides an electric wire and cable material and a preparation method of same and relates to the field of electricity materials. The electric wire and cable material includes, by weight, polyvinyl chloride resin, methyl vinyl silicon rubber, ethylene-vinyl acetate copolymer, nano-active calcium carbonate, color powder, polyethylene wax, talcum powder, ceramic fibers, floating beads, brown corundum, a plasticizer, a compatilizer, a flame retarding agent, an antioxidant, a photostabilizer, and a thermal stabilizer. The preparation method includes the steps of: 1) weighing raw materials; 2) stirring the raw materials in a high-speed mixing machine; 3) stirring the raw materials in a cold-stirring machine; 4) feeding the raw materials in a granulator. The preparation method solves the problems of insufficient flame-retarding property, mechanical strength, toughness and anti-aging property of electric wire and cable materials in the prior art.

Description

technical field [0001] The invention belongs to the field of electric power materials, and in particular relates to a wire and cable material and a preparation method thereof. Background technique [0002] With the improvement of people's safety awareness, people have higher and higher requirements for the flame retardancy of wires and cables. Flame-retardant and fire-resistant wires and cables are currently a focus of people's attention. In all areas of electrical power applications, the fire resistance of wires and cables plays a very important role in ensuring the integrity and effectiveness of electrical systems. In many large-scale fire accidents in public places, the cause of most of the deaths is suffocation due to inhalation of corrosive and toxic smoke gases released from burning wires and cables (polymers). Flame retardant treatment of wire and cable materials has been recognized as an important measure to fundamentally prevent and reduce fires and reduce people's...
