The invention discloses a semi-inorganic silicon steel sheet paint and a preparation method and application thereof, comprising: polyamideimide clear emulsion, titanium dioxide, silicon dioxide, barium sulfate and amino resin, and preparation of polyamideimide clear emulsion : Under the protection of protective gas and under the reflux state, make trimellitic anhydride react with a specific compound double-ended amino compound in the first organic solvent, add tributyl phosphate and triethylamine, and react; steam the first organic solvent outward, Add the second organic solvent, add linear alkyl benzene sulfonate sodium, fatty alcohol polyoxyethylene ether sodium sulfate and fatty alcohol polyoxyethylene ether, mix, add water dropwise under stirring conditions, and after the dropwise addition, add bismaleate The semi-inorganic silicon steel sheet paint is made by mixing and ultrasonically dispersing the various components, and can be used as a covering paint in silicon steel sheets, and not only can water be used as the main solvent, and it is environmentally friendly. , and also has the advantages of high temperature resistance, high bonding strength and strong electrical properties. |
