Abstract

The invention relates to the technical field of coatings, in particular to a fireproof insulating coating and a preparation method thereof.The fireproof insulating coating is formed by mixing a polyamideimide resin coating and organic silica sol, the polyamideimide resin coating comprises a solvent and polyamideimide resin, and the organic silica sol comprises, by weight, 20-30% of adhesive tape material, which comprises two layers of adhesive tape bodies and silicon dioxide particles uniformly dispersed between the two layers of adhesive tape bodies, each adhesive tape body is prepared by drying base cloth and an emulsion adhesion layer coated on the base cloth, and when the two layers of adhesive tape bodies are adhered, the base cloth faces outwards, and the emulsion adhesion layers aremutually adhered into a whole. According to the invention, the adhesive tape body in the adhesive tape material is used as a carrier to carry the silicon dioxide particles, the adhesive tape materialis uniformly dispersed through the mixing process to realize the dispersion uniformity of the silicon dioxide particles, and the toughness of the insulating film can be greatly improved while the fireproof and insulating requirements are satisfied.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a fireproof insulating coating and a preparation method thereof. Background technique [0002] In recent years, in response to demands for miniaturization, high performance, and energy saving of electric appliances, inverter control of electric appliances at high voltage and high current has been widely performed. In this case, due to the inverter control, a high inverter surge voltage is often generated in the appliance, and once such an inverter surge voltage is generated, it may have a bad influence on the insulation system of the coil in the appliance. In particular, in insulated wires used for coils, partial discharge mainly occurs between wires or between grounds, and the generation of this partial discharge causes erosion of the insulating film and even causes a problem of dielectric breakdown. As the insulated wire used in the coil of such an electric appliance, an insu...
