Novel flame-retardant cable material and preparation method thereof

Abstract

The invention discloses a novel flame-retardant cable material. The cable material is prepared from raw materials in parts by weight as follows: 15-35 parts of polyvinyl chloride, 3-8 parts of an ethylene-octylene copolymer, 13-18 parts of ethylene-vinyl acetate, 18-33 parts of high impact polypropylene, 7-18 parts of nitrile rubber, 1-2 parts of stearic acid, 12-23 parts of filler, 1.5-3.3 parts of a heat stabilizer, 0.7-1.2 parts of an antioxidant, 1-2 parts of an antibacterial agent, 4-8 parts of a plasticizer, 3-5 parts of a compatilizer and 1-3 parts of a flame retardant. The novel flame-retardant cable material has excellent performance, good physical performance, wide temperature adaptation range, high-temperature resistance, good flame-retardant performance, antibacterial and anti-corrosion capacity and long service life.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to a novel flame-retardant cable material and a preparation method thereof. Background technique [0002] With the rapid development of the economy, wires and cables are widely used in various industries and fields. While the consumption of wires and cables is increasing, the accidents of electrical fires are also increasing. The safety, environmental protection and service life of wire and cable products have higher requirements. The flame retardant problem of wires and cables has gradually attracted the attention of countries all over the world. . As early as the 1970s, flame-retardant cables were developed successively at home and abroad. Although these flame-retardant cables have certain flame-retardant effects, they still have many defects, such as poor high-temperature resistance and cannot work at high temperatures; insufficient aging resistance , the service lif...

Problems solved by technology

As early as the 1970s, flame-retardant cables were developed successively at home and abroad. Although these flame-retardant cables have certain flame-retardant effects, they still have many defects, such as poor high-temperature resistance and cannot work at high temperatures; insufficient aging resistance , the service life is short, and it is easy to cause a fire; when a fire occurs, the burning wires and cables will produce toxic gases and smoke, which will not only affect the disaster relief work, but also cause "second disasters" to life and property
