Abstract

The invention discloses a power distribution cabinet epoxy coating with good air tightness. The materials comprises, by weight, 30-50 parts of bisphenol A-type epoxy resin, 10-20 parts of glycidyl ester type epoxy resin, 15-25 parts of bisphenol F-type epoxy resin, 4-10 parts of modified asbestos, 4-8 parts of barium titanate, 8-16 parts of zeolite, 4-8 parts of molybdenum disulfide, 4-8 parts of mica powder, 4-8 parts of attagel, 6-12 parts of aluminum borate whisker, 3-7 parts of magnesium hydrate, 4-8 parts of barium metaborate, 10-16 parts of zinc phosphate, 4-8 parts of trimethyl phosphate, 2-4 parts of film coalescing aid, 10-18 parts of diamine methyl cyclohexane, 4-8 parts of defoaming agent, 1-3 parts of antimicrobial agent, 10-20 parts of poval and 50-90 parts of water. The power distribution cabinet epoxy coating with good air tightness not only has a good air tightness, but also has a strong surface adhesion, an ultrahigh heat stability and anti-corrosion property, at the same time, the coating toughness is effectively strengthened, and even in the face of strong impact, the coating does not crack.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an epoxy coating with good airtightness for the shell of a power distribution cabinet. Background technique [0002] Coating is a general term for a class of liquid or solid materials that can form a solid coating film with protection, insulation, anti-corrosion, marking, etc. on the surface of an object. 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. It is suitable for the anti-rust primer of epoxy coating for the outer shell of the distribution cabinet. Some epoxy coatings provided by the prior art have poor air tightness, and the bonding performance cannot meet the requirements, resulting in easy oxidation and deformatio...
