Problems solved by technology

[0004] The Chinese patent application number CN02100832.9 discloses a coating based on acrylic resin with the function of reflecting solar heat energy. This coating formed by the coating of acrylic resin as the main film-forming material is not harmful to the sun. The absorption rate of heat energy is low and the weather resistance is good, but its anti-corrosion performance is not so ideal, so it is not suitable for use in chemical equipment that requires high anti-corrosion performance

Embodiment 1

[0014] An anti-corrosion composite coating for motors is located on the surface of the insulation structure of the motor. The composite coating is composed of a bottom layer, a middle layer and a surface layer. The bottom layer is acrylic / epoxy resin primer, which is sprayed directly on the surface of the motor insulation structure; the middle layer is epoxy resin paint, which is sprayed on the first coat; the top layer is silicone polyurethane resin paint, which is sprayed on the middle layer.

[0015] The bottom layer includes the following components: in parts by weight, 40-50 hydroxyacrylic resin as the base material, 14-18 nano-titanium dioxide-based composite particles, 8 silicon-aluminum-based hollow microspheres, 12 mica powder, 3 talc powder, and 2 xylene , BYK-182 dispersant 0.4, BYK-024 defoamer 0.3, LXE fungicide 0.2; primer: H-2 curing agent = 10:1.

[0016] The middle layer includes the following components: in parts by weight, heat-resistant unsaturated polyeste...

Abstract

The invention provides an anticorrosive composite coating of a motor. The anticorrosive composite coating of a motor is positioned on the surface of the insulation structure of the motor, and is formed by compounding a base layer, an interface layer and a surface layer, and the base layer is obtained by directly spraying an acrylic acid/epoxy resin priming paint on the surface of the insulation structure of the motor; the interface layer is obtained by spraying an epoxy resin paint on the obtained first coating (base layer); and the surface layer is obtained by spraying an organosilicon polyurethane resin paint on the interface layer. The anticorrosive composite coating of the motor can effectively resist salt spray, moist, solvents, radiation, low temperature, hot and cold impact, wear and the like.

Description

Background technique [0001] At present, explosion-proof three-phase explosion-proof asynchronous motors used in underground mines, motors used in seaside mud pumps, motors used in the humid tropical regions of island countries, and outdoor motors in the north often burn out within 1 to 2 months, causing users to work abnormally. , The motor manufacturer has suffered a great loss in customer service. What is the reason? 1) The temperature difference between hot and cold is large, resulting in a serious drop in the insulation resistance of the motor due to condensation at the coil end of the motor. 2) The temperature in the humid tropics is sometimes over 95%, and there is mold, and the damp mold causes a serious drop in the insulation resistance of the motor. 3) The sea breeze blows the salt mist into the condensate on the wire wrap of the motor. Salt is a conductor, which damages the insulation and conduction of the motor. At present, some scientific research units and manufa...
