Problems solved by technology

[0003] Most of the existing insulating varnishes are epoxy systems. This is due to the outstanding anti-corrosion and insulating properties of epoxy systems. However, the ether bonds in epoxy resins are easily broken by ultraviolet radiation, resulting in aging and powdering of the coating. At the same time, these insulating varnishes Not flame retardant

Abstract

The invention relates to a flame-retardant insulating paint, belonging to the technical field of paint. The flame-retardant insulating paint comprises the following components in parts by weight: component A: 100-120 parts of epoxy resin, 7-10% of magnesium hydroxide whisker, 6-12 parts of Tetraphenyl resorcinol bis(diphenylphosphate), 10-25% of silica micropowder, 4-8 parts of 2,4-dihydroxybenzophenone, 0-5 parts of pigments, 0.5-2 parts of polycarboxylic acid sodium salt, 0.2-0.5% of defoaming agent, 5-10 parts of acetone, and 8-15 parts of ethyl acetate; component B: 2-10 parts of curing agent. The paint not only has the advantages of being strong in adhesion force, high in mechanical strength, good in high temperature resistance property, excellent in anti-corrosion and humidity resistance properties, fast in low-temperature drying speed, and good in storage stability, but also has excellent flame-retardant property, electric insulating property and anti-ultraviolet property, and can be used for flame-retardant insulating paint for surfaces of conductors in various electrical devices.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a flame-retardant insulating coating. Background technique [0002] With the development of science and technology, people have higher and higher requirements for the performance of insulating materials, and the development of insulating materials with excellent performance is a worldwide topic in the field of electrical and electrical materials. Insulating coatings not only have the high temperature resistance, anti-corrosion and moisture-proof properties of coatings, but also have excellent electrical insulation properties, and are widely used in motors, transformers, etc. [0003] Most of the existing insulating varnishes are epoxy systems. This is due to the outstanding anti-corrosion and insulating properties of epoxy systems. However, the ether bonds in epoxy resins are easily broken by ultraviolet radiation, resulting in aging and powdering of the coating. At ...
