Insulating coating and processing technology thereof

Abstract

The invention provides an insulating coating and a processing technology thereof. The problem that an existing coating is short in service life is solved. According to the insulating coating and the processing technology thereof, the insulating coating is composed of the following materials in parts by mass: 90-110 parts of organic silicon powder solid resin, 75-150 parts of a combined solvent, 8-12 parts of a thermoplastic elastomer, 3-10 parts of a fluorine surfactant, 50-80 parts of ultrafine mica powder, 2-9 parts of nano silicon dioxide and 3-8 parts of alkyl silicone oil, wherein the combined solvent is used for dissolving the organic silicon powder solid resin. The process comprises the following steps: A, preparing the combined solvent; B, adding nano silicon dioxide; C, adding theorganic silicon powder solid resin; D, adding the thermoplastic elastomer; E, adding the fluorine surfactant; F, adding alkyl silicone oil; and G, adding superfine mica powder. The insulating coatingand the processing technology thereof are long in service life.

Description

technical field [0001] The invention relates to an insulating paint, in particular to an insulating paint and a processing technology thereof. Background technique [0002] For a long time, ceramic and glass insulators have been widely used in the field of transmission and distribution lines due to their advantages of high mechanical strength, good electrical insulation performance and long-term outdoor aging resistance. However, the hydrophilicity of the surface of ceramic and glass insulators causes the overall insulation level of the insulator to drop in rainy or humid weather, especially after the surface of the insulator is polluted, and the dirt is damp under drizzle, fog or dew, and the creepage distance rapidly increases. Reduced, resulting in wet flash, pollution flash operation accidents, large-scale power outages, serious losses to the national economy and people's lives.

Problems solved by technology

However, the hydrophilicity of the surface of ceramic and glass insulators causes the overall insulation level of the insulator to drop in rainy or humid weather, especially after the surface of the insulator is polluted, and the dirt is damp under drizzle, fog or dew, and the creepage distance rapidly increases. reduction, resulting in wet flash, pollution flash operation accidents, large-scale power outages, and serious losses to the national economy and people's lives

[0003] In response to the above problems, people have invented a composite insulator and RTV silicone rubber anti-fouling flashover coating, which can effectively improve the anti-fouling flashover and wet flashover levels of ceramic and glass insulators, but the above-mentioned coating has the problem of poor anti-ultraviolet weather ability, resulting in Its lifespan is short, and it is easily damaged by bird pecks and insect bites

[0004] At the same time, for wave-transmitting equipment such as telecommunications, aerospace, antennas and radomes, the dielectric constant and dielectric loss will be greatly reduced after being damp, which will seriously affect the wave-transmitting performance and even fail to wave-transmitting
