High-temperature-resistant coating material composition for transformer and preparation method of high-temperature-resistant coating

Abstract

The invention discloses a high-temperature-resistant coating material composition for a transformer and a preparation method of a high-temperature-resistant coating. The composition is prepared from organic silicon rubber, hydroxyethyl cellulose, talcum powder, aluminum oxide, magnesium oxide, calcium stearate, graphite, xylene and n-butyl alcohol, wherein relative to 100 weight parts of the organic silicon rubber, the content of the hydroxyethyl cellulose is 10-50 weight parts, the content of the talcum powder is 10-40 weight parts, the content of the aluminum oxide is 5-20 weight parts, the content of the magnesium oxide is 5-20 weight parts, the content of the calcium stearate is 10-30 weight parts, the content of the graphite is 10-20 weight parts, the content of the xylene is 20-50 weight parts, and the content of the n-butyl alcohol is 10-30 weight parts. By the adoption of the design, effective high temperature resistance is achieved, seasoning cracks and other problems will not appear even in a high temperature environment, and production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of production and preparation of coatings for transformers, in particular to a high-temperature-resistant coating material composition for transformers and a preparation method for high-temperature-resistant coatings. Background technique [0002] In the actual production and use of transformers, the temperature in the environment is often high. Therefore, in actual use, the paint coated on the surface is often prone to dry cracking and deformation due to excessive temperature, which makes the paint fall off and makes the transformer There is no protective layer on the surface, and its service life will be greatly reduced in the later use process. However, in the production process, if maintenance personnel are frequently asked to perform operations such as painting, it will not only take time and effort, but also greatly improve the production efficiency. Production costs, and normal production is often not possible ...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned prior art, the purpose of the present invention is to overcome the high temperature of the environment in which the transformer is used in the prior art, causing the coating to fall off, and leaving no protective layer on the surface of the transformer, which often shortens its service life during later use. It is greatly reduced, but in the production process, if maintenance personnel are frequently asked to perform operations such as painting, it will not only take time and effort, but also greatly increase the production cost in production, and it is often impossible to carry out normal production during the time until the paint is dry. , thereby providing a high temperature resistant coating material composition and a method for preparing a high temperature resistant coating for transformers that can effectively withstand high temperatures, so that problems such as dryness and cracking will not occur in high temperature environments, and the production efficiency is greatly improved
