Coating with lightning-protection function for transformer production

Abstract

The invention discloses a coating with a lightning protection function for transformer production. The coating is prepared from the following components: waterborne polymer resin, tackifying resin emulsion, vulcanized silicone rubber particles, silica powder, acrylic resin, a wetting dispersant, a defoaming agent, a thickening agent, a toughening agent, a carbon nano-material, a modifier, an anti-seepage agent, a preservative, mica powder and nano diatomite powder. The water-based polymer resin is used as a raw material, so that the coating is low in cost and good in waterproofness; and the tackifying resin emulsion is added, so that the bonding strength of the coating can be ensured. The coating has the effects of lightning protection, static electricity resistance, water seepage prevention, corrosion resistance, aging resistance, good insulation effect, wear resistance, firmness and strong weather resistance, has good adhesiveness and sealing performance, is acid-resistant and high-temperature-resistant, can meet the maintenance requirements of external equipment of various power systems, and prolongs the service life.

Description

technical field [0001] The invention belongs to the technical field of transformers, and more specifically relates to a coating with lightning protection function for transformer production. Simultaneously, the invention also relates to a preparation method of a paint with lightning protection function for transformer production. Background technique [0002] The so-called paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, oil, or emulsion, with or without adding pigments, fillers, adding The corresponding additives are viscous liquids prepared with organic solvents or water. Coatings are widely used, and their main function is to improve the functionality of the product itself, and at the same time improve the appearance of the product. In the field of transformer production technology, the use of coatings is also popular, but most of the existing coat...

Problems solved by technology

Coatings are widely used, and their main function is to improve the functionality of the product itself, and at the same time improve the appearance of the product. In the field of transformer production technology, the use of coatings is also popular, but most of the existing coatings are anti-corrosion. Anti-aging and other functions. For electronic components such as transformers, the coating on the surface of the product should not only have these functions, but also need the functions of anti-static and lightning protection. The existing coatings do not have lightning protection. Therefore, the existing coatings cannot meet the coating requirements of existing transformers, and the service life is short, which is not conducive to extensive promotion and popularization
