Problems solved by technology

[0003] Power cables are prone to aging, corrosion, and damage in outdoor environments, especially in hot and humid climates or areas with severe acid-base and salt effects, which can easily cause transmission line failures and bring more trouble to people's normal production and life. Great impact, but also cause greater losses to the power sector
[0004] When the line fails, it is very likely that local heating will generate high temperature, which will cause a fire and cause huge losses to people's lives and property.

Abstract

The invention discloses a special coating for a cable conductor, and a preparation method thereof. The special coating is prepared from, by weight, 80-150 parts of polyvinyl chloride resin, 20-40 parts of acrylic acid, 10-15 parts of N-methylpyrrolidone, 5-30 parts of polyoxyethylene lauryl ether, 15-40 parts of emulsified silicone oil, 10-30 parts of phthalate, 10-20 parts of antimony trioxide, 10-15 parts of borax, 5-15 parts of sodium silicate, 5-20 parts of white graphite, 5-10 parts of aluminum tripolyphosphate, 20-30 parts of silica gel nano-powder, 10-20 parts of nanometer titanium dioxide, 40-60 parts of deionized water, 15-40 parts of a flame retardant filler, 5-20 parts of a waterproof agent and 2-5 parts of a defoamer. The reasonable raw materials and the reasonable ratio of theraw materials are selected, and all the raw materials synergistically act and complement each other, so the special coating for the cable conductor has strong resistance to acids, alkalis, salts, flame, moisture and water, and effectively prolongs the service life of the cable conductor.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a special coating for cables and a preparation method thereof. Background technique [0002] In the power supply system, the power cable is an important transmission line, which is made of one or more mutually insulated conductors and an outer insulation protection layer, and is used to transmit power or information from one place to another. [0003] Power cables are prone to aging, corrosion, and damage in outdoor environments, especially in hot and humid climates or areas with severe acid-base and salt effects, which can easily cause transmission line failures and bring more trouble to people's normal production and life. Large impact, but also cause greater losses to the power sector. [0004] When the line fails, it is very likely that local heating will generate high temperature, which will cause a fire and cause huge losses to people's lives and property. Con...
