Single-component water-soluble insulated enamel paint and preparation method thereof

Abstract

The invention relates to single-component water-soluble insulated enamel paint and a preparation method thereof. The single-component water-soluble insulated enamel paint is characterized by consisting of the following components in part by weight: 26 to 33 parts of water-soluble acrylic resin, 6.5 to 11 parts of amino resin curing agent, 28 to 36 parts of water, 1.7 to 2.4 parts of neutralizing agent, 2.5 to 5 parts of latent solvent, 31 to 37 parts of pigment and filler, 0.1 to 0.3 part of wetting agent, 0.1 to 0.3 part of dispersing agent, 0.1 to 0.3 part of defoaming agent and 0.1 to 0.3 part of flatting agent. The single-component water-soluble insulated enamel paint of the invention has the advantages that: the enamel paint does not need preparing during use and is rapid and convenient to use; paint liquid has high storage stability; combustion and explosion dangers are avoided; exhaust emission pollution is avoided, air environments of a workshop and a plant can be improved andharm to human body is reduced; and a paint film is yellowing-resistant at a high temperature and has large hiding power and good decorating and beautifying effects.

Description

technical field [0001] The invention relates to a single-component water-soluble insulating enamel and a preparation method thereof. The prepared water-soluble insulating enamel can be widely used in surface decoration of ballasts, low-voltage small transformers, inductors, etc., and deep insulation treatment inside coils. Technical field of electrical insulation treatment. Background technique [0002] In recent years, due to the rapid development of the domestic electronic and electrical industry, the number of ballasts, small transformers and inductors used has increased rapidly. Especially in the era of advocating energy saving and emission reduction, ballasts are the heart of fluorescent lamps and energy-saving lamps, and the market is broader. In the production process of ballasts, small transformers and inductors, the process of impregnating insulating enamel is involved. The main purpose of impregnating varnish is to strengthen the insulation performance and beauti...

AI Technical Summary

Problems solved by technology

Water-based enamel generally uses emulsion as the matrix resin, which is easily affected by light, heat, acid and alkali, impurities, etc. after being made into a paint solution, resulting in poor stability; The color and appearance of the paint will be adversely affected, and the water resistance of the paint film will be reduced, so it cannot be used in the field of electrical insulation treatment
