Insulation coating material for electric power device

Abstract

The invention discloses an insulation coating material for an electric power device, and belongs to the technical field of a coating material, which solves the problems that the existing insulation coating material is poor in adhesive force and poor in corrosion resistance. The insulation coating material is prepared from the following raw materials in parts by weight: 30 to 40 parts of organic silicon resin, 10 to 20 parts of epoxy resin, 5 to 10 parts of dimethyl siloxane, 3 to 5 parts of methylbenzene, 13 to 18 parts of n-butyl alcohol, 1 to 3 parts of dimethyl terephthalate, 1 to 2 parts of polyethylene, 1 to 3 parts of butyl acrylate, 1 to 3 parts of hydroxyethyl acrylate, 5 to 10 parts of polyethylene wax, 0.5 to 1 part of polyamide epoxy curing agent, 1 to 3 parts of modified polyester silane, 2 to 5 parts of silicon nitride, 1 to 3 parts of magnesium oxide and 0.3 to 1 part of polyether modified organic silicon defoaming agent. The insulating coating material can be used for a majority of electric power devices and is particularly suitable for the electric power device working in a dirty and wet environment.

Description

technical field [0001] The invention relates to an insulating coating used for electric equipment, belonging to the technical field of coatings. Background technique [0002] Coating a layer of insulating material on the surface of power equipment or some equipment protection devices can not only improve the external insulation of power equipment, improve the safety of power systems, but also improve the reliability of system operation. There are many types of insulating materials, such as insulating encapsulation materials, insulating paper, insulating plastics, insulating coatings, etc. Among them, insulating coatings are more and more applied to insulating equipment in various industries due to their simple preparation method and convenient construction process. . [0003] At present, there are many kinds of insulating coatings that can be adapted to high-temperature environments. These coatings can still maintain good dielectric properties and have good insulation prope...

Problems solved by technology

However, due to the formulation and process problems of the paint itself, these paints will cause a decrease in adhesion or even fall off in a dirty and humid environment, and the anti-corrosion ability is poor.
