Abstract

The invention belongs to the technical field of coatings and particularly relates to a waterproof anti-oxidation insulating paint for a power device. The protective oil paint is prepared from priming paint and waterproof finish paint and contains dimethylbenzene, alkyd resin, aluminum powder slurry, porcelain clay, talcum powder, a plasticizer, silica and glycol ether. The waterproof finish paint contains polyether polyol, isocyanate, titanium dioxide powder, trimethyl monochlorosilane, fatty alcohol polyoxyethylene ether, a leveling agent and a cosolvent. When the waterproof anti-oxidation insulating paint is used, the priming paint is sprayed firstly, and then the finish paint is sprayed after the priming paint is dried. The protective paint has good oxidation-resistance, corrosion-resistance and waterproof properties, strong adhesive powder and uniform, fine and smooth paint surface and is very suitable for power device surfaces.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a waterproof and oxidation-resistant insulating varnish for electric equipment. Background technique [0002] Power equipment is used in the whole process from power generation, power transmission to power transformation, power distribution and power consumption to form a complete system of power production and consumption. These equipments have high technological content and high value; except for a few precision core equipments located indoors, most of the equipments are located outdoors, directly facing harsh natural conditions, so the requirements for equipment protection are relatively high. Painting the surface of some metal parts is part of the protective measures. [0003] Conventional metal protective paints for equipment on the market can also be used, but these paints and coatings are not specially configured for the use scenarios of power equipment. They...
