A flame-retardant water-based insulating paint is characterized in that, in terms of mass percentage, the raw materials of the flame-retardant water-based insulating paint include the following components: the hyperbranched water-based epoxy resin emulsion is made of polyether polyol , Bisphenol A type epoxy resin and hyperbranched epoxy resin are dispersed in the second solvent after reacting, the solid content of the hyperbranched waterborne epoxy resin emulsion is 50-60%, the first solvent, the The second solvent is water.

The invention discloses a flame-retardant water-based insulating paint and its preparation method and application.

Its raw materials include the following components: hyperbranched waterborne epoxy resin emulsion; blocked isocyanate; waterborne amino resin; hyperbranched polyamide resin; hyperbranched Polyphosphate; the first solvent; hyperbranched waterborne epoxy resin emulsion is made by reacting polyether polyol, bisphenol A epoxy resin and hyperbranched epoxy resin and then dispersed in the second solvent, hyperbranched waterborne epoxy resin The solid content of the oxygen resin emulsion is 50%-60%, the first solvent and the second solvent are both water; preparation: first prepare the hyperbranched waterborne epoxy resin emulsion, and then weigh the raw materials according to the formula, mix them, and make ; And the application of the above-mentioned flame-retardant water-based insulating paint in motors and electronic transformers; the water-based insulating paint of the present invention not only has excellent environmental performance, but also has excellent flame-retardant performance, bonding strength and excellent water and salt resistance Fog and other properties.
