COATING SOLUTION OF NON-ORIENT ELECTRICAL STEEL SHEET, METHOD FOR COATING NON-ORIENT ELECTRICAL STEEL SHEET USING THE SAME, AND COATING FILM OF NON-ORIENT ELECTRICAL STEEL SHEET
COATING SOLUTION OF NON-ORIENT ELECTRICAL STEEL SHEET, METHOD FOR COATING NON-ORIENT ELECTRICAL STEEL SHEET USING THE SAME, AND COATING FILM OF NON-ORIENT ELECTRICAL STEEL SHEET
A coating solution of non-orient electrical steel sheet, a method for coating non-orient electrical steel sheet using the same, and a coating film of non-orient electrical steel sheet are provided to improve high insulation capacity and heat resistance of the non-orient electrical steel sheet by using 2 kinds of inorganic fillers having excellent heat resistance. Coating solution of a non-orient electrical steel sheet includes barium sulphate(Ba2SO4) of 20-40 weight%, titanium oxide(TiO2) of 10-20 weight%, ionized water of 15-30 weight%, and melamine resin of 30-50 weight% containing glycerine and ethylene glycol which is high-boiling solvent. The barium sulphate is the size of 1-3 micron and has a bar pillar shape. The barium sulphate has dispersibility with the melamine resin and solution stability. The titanium oxide has a rectangle shape and has the size of 50-200nm.
