Insulating coating material for electrical equipment

Abstract

The invention relates to an insulating coating material for electrical equipment, wherein the components comprise an epoxy resin, magnesium oxide, silicon nitride, alumina, linoleic acid, acrylic acid, diantimony trioxide, a toughening agent, an antifoaming agent, a leveling agent, and vinyl benzene. The insulating coating material prepared by using the formula of the present invention has characteristics of toughness, high thermal conductivity and good thermal stability of the metal, high temperature resistance, corrosion resistance and wear resistance of the ceramic, improvement of comprehensive performances of mechanical shock resistance and thermal shock resistance, good insulating property, excellent weather resistance, excellent aging resistance, good adhesion with a variety of metal substrates, high solid content, low volume shrinkage rate during drying curing, and simple, and convenient and rapid production, and can not be subjected to embrittlement cracking due to sudden cooling or heating.

Description

technical field [0001] The invention relates to a coating, in particular to an insulating coating for electric equipment. Background technique [0002] A layer of insulating material, such as insulating paint, insulating varnish, etc., is often coated on the surface of power equipment or some equipment protection devices, which can improve the external insulation of power equipment, not only improve the safety of the power system, but also improve the reliability of the system operation. Reliability saves the cost of power equipment to a certain extent. [0003] In the current industry, there are many types of insulating coatings. Because of the differences in coating formulations and processing techniques, the performance of insulating coatings is also uneven. Traditional insulating coatings often use chromate as a component, and chromate is highly toxic and polluting, causing harmful effects on the human body and the environment. Many well-known domestic companies' electr...
