Heat-resistant and corrosion-resistant epoxy coating for heat-resistant and corrosion-resistant power distribution cabinet shell

Abstract

The invention discloses a heat-resistant and corrosion-resistant epoxy coating for a heat-resistant and corrosion-resistant power distribution cabinet shell. The heat-resistant and corrosion-resistant epoxy coating is prepared from the following raw materials in parts by weight: 20-40 parts of bisphenol A type epoxy resin, 10-20 parts of polyphenols glycidyl ether epoxy resin, 5-15 parts of novolac epoxy, 6-14 parts of aminoethyl piperazine, 1-2 parts of coalescing agent, 2-4 parts of trimethyl phosphate, 2-6 parts of modified asbestos, 2-4 parts of zeolite powder, 6-10 parts of mica powder, 2-4 parts of glass beads, 1-6 parts of porous powder quartz, 2-6 parts of coal ash, 1-4 parts of cornstalk, 2-5 parts of bentonite, 1-4 parts of carbon black, 5-12 parts of zinc phosphate, 0.5-1.5 parts of antibacterial agent, 2-4 parts of defoaming agent, 5-15 parts of polyvinyl alcohol, and 40-80 parts of water. The epoxy coating disclosed by the invention has extremely high heat stability and corrosion resistance, is not only excellent in airtightness, and but also strong in surface adhesion; and meanwhile, the smearing tenacity can be effectively enhanced, and the smeared coating is hard to break even encountering strong impact.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an epoxy coating for the shell of a heat-resistant and corrosion-resistant power distribution cabinet. Background technique [0002] Paint is a general term for a class of liquid or solid materials that can form a solid coating film with protective, decorative or special properties when applied to the surface of an object. Coatings can be resin or oil-based viscous liquids prepared with organic solvents or water, or solid powders. According to the different film-forming substances in the coating, the coating can be divided into alkyd coating, acrylic coating, epoxy coating and polyurethane coating, etc. Among them, epoxy coating has the advantages of convenient curing, strong adhesion, low shrinkage and good mechanical properties. And electrical performance and other advantages, suitable for power distribution cabinet shell. However, the heat resistance, bonding performance an...
