Corrosion-resistant covering paint for transformer iron core and preparation method thereof

Abstract

The invention discloses a corrosion-resistant covering paint for a transformer iron core and a preparation method thereof. The raw materials of each component are as follows, in parts by weight, including 10-15 parts of polyamide, 0.5-1 part of filler, and 1-2 parts of antioxidant 0.3-0.4 parts of antistatic agent, 1-3 parts of plasticizer, 2-4 parts of polyamine, 20-30 parts of pyrrolidone, 5-10 parts of glycerin, wherein antioxidants are hindered amine compounds, methacryloyl A mixture of oxysilanes. The present invention chooses to use polyamide as the main material for processing. Polyamide has strong wear resistance and excellent sound absorption, which can increase the overall performance of the product. Add antistatic agents sodium oleate, dodecyl di Methyl benzyl ammonium bromide, hexadecyl trimethyl ammonium bromide, because the antistatic agent contains halogen, need to control the amount used, after the present invention adds antistatic agent, can guarantee that the content of halogen is less than 1% , thus ensuring the safety of use and preventing environmental pollution and human injury.

Description

Corrosion-resistant covering paint for transformer iron core and preparation method thereof technical field The present invention relates to the technical field of varnish preparation, in particular to a kind of corrosion-resistant varnish for transformer core and preparation thereof. preparation method. Background technique Transformer is a common electrical equipment, due to the working nature of the transformer, it has a certain The paint used in the press needs to have certain special properties. [0003] The coating is also called paint, which is used to coat the surface of the protected object and exists in the form of a film on the surface of the object. Now, the protected object can be simply isolated from water, air, etc., which greatly enhances the anti-oxidation, Corrosion resistance. The main component of the coating is mainly resin, which is mixed with some additives and other substances, which can greatly increase the All aspects of the strong produc...

Problems solved by technology

[0004] Transformers need to work all year round, and need to have good corrosion resistance and impact resistance. In order to improve performance, common paints on the market add a large amount of organic chemicals and metal elements, resulting in excessive heavy metal content and decreased antistatic performance. , and the paint used in transformers needs to have certain antistatic properties, so it is particularly important to invent a corrosion-resistant covering paint for transformer cores and its preparation method
