Abstract

The invention discloses an efficient flame-retardant cable material for a railway locomotive. The efficient flame-retardant cable material is prepared from the following raw materials in parts by weight: 5-7 parts of magnesium hydroxide, 9-11 parts of kaolin, 6-8 parts of polyaluminum chloride, 6-8 parts of tin-bismuth alloy powder, 26-33 parts of polypropylene, 6-7 parts of ammonium polyphosphate, 7-9 parts of conductive mica powder, 3-4 parts of stearic acid, 1-2 parts of polyacrylamide, 0.4-0.6 part of an anti-oxidant 1680, 48-55 parts of ethylene propylene terpolymer, 30-35 parts of polyolefin, a proper amount of absolute ethyl alcohol and a proper amount of deionized water. According to the efficient flame-retardant cable material, the water resistance and moisture resistance of the material can be remarkably improved, and dialysis resistance, in a high polymer material, of a filler is improved; the efficient flame-retardant cable material is efficient, flame-retardant, moisture-proof and waterproof, safe and environmentally-friendly, good in heat resistance, high in oil resistance and chemical resistance, long in service life, and worthy of being popularized.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a high-efficiency flame-retardant cable material for railway locomotives. Background technique [0002] Polymers are widely used in various fields of production and life due to their low price, light texture, high specific strength, small thermal conductivity and good chemical stability. Most polymers are good electrical insulators with high resistivity and are prone to static electricity, which limits their applications. Antistatic hazards are becoming more and more serious, such as interfering with the normal operation of aircraft radio equipment, affecting the operation of aircraft, and the polymer shell of pharmaceutical factory equipment is prone to electrostatic adsorption of dust, affecting the purity of drugs, etc. In recent years, the national railway traffic has developed rapidly, and railway The control of the system is becoming more and more complex, there ar...
