anti-corrosion coating for cables

Abstract

The invention discloses an anticorrosion coating for a cable. The anticorrosion coating is prepared from, by weight, 5-10 parts of modified polysiloxane emulsion, 10-20 parts of asphalt, 5-10 parts of polyacrylate, 20-50 parts of dimethyl carbonate, 1-3 parts of an antioxidant, 0.5-1 part of zinc oxide, 1-5 parts of silicon rubber, 0.1-0.5 part of alkylphenol polyoxyethylene and 0.1-0.3 part of a nonionic fluorocarbon surfactant. The anticorrosion coating for the cable has advantages remarkable adhesion, excellent weather resistance, quickness in drying and resistance to high and low temperatures.

Description

technical field [0001] The invention relates to a cable anticorrosion coating and a preparation method thereof, in particular to a cable protective coating used in sea or high saline environment. Background technique [0002] Cable is a kind of power equipment widely used in industry, especially in the production sites of chemical, pharmaceutical, oil field and other industries, there are often acid, alkali or organic solvent pollution and corrosion. Since the sheath and outer insulation of ordinary cables are mainly various high molecular polymers, they are sensitive to organic solvents and acid-base conditions. In the case of long-term acid-base or organic solvents, they are easily corroded by organic solvents, resulting in acid-base The conductor is supported by the sheath and the insulating layer, resulting in a decrease in the insulation performance of the cable, a short service life, and frequent replacement, resulting in waste of resources, affecting production, and b...

Problems solved by technology

[0003] The commonly used cable anti-corrosion coatings in the prior art generally adopt asphalt coatings by brushing, but the existing problems are: the anti-corrosion substrate has high requirements for treatment, the coating film is too thick and easy to crack, and the coating film is greatly affected by temperature and humidity when it is cured. The curing time is long, and most of them have the disadvantages of poor weather resistance and weak adhesion, so the anti-corrosion performance is generally not ideal

As a coating, it is composed of a variety of chemical components, scientifically formulated, and unique physical and chemical reactions. If the formula and process are unreasonable, even if some nano-scale raw materials are added, the quality will not be greatly improved. On the contrary will lead to an increase in the cost of the industry
