摘要
PURPOSE: An insulation coating agent of a non-orient electrical steel sheet is provided to form an insulation film with excellent corrosion resistance and adhesion after annealing without chrome harmful to the human body. CONSTITUTION: An insulation coating agent of a non-orient electrical steel sheet comprises: 47-57 parts by weight of metal oxide composite salts formed by the reaction of inorganic metal oxides with oxygen acids; 25-35 parts by weight of self-crosslinkable emulsion resins; 0.1-0.5 parts by weight of non-silicone-based additives for improving wettability; 5-10 parts by weight of propylene glycol for preventing smudge; 3-7 parts by weight of phosphoric acid-epoxy silane compounds for improving the glossiness and adhesion of the insulation film; and 3-7 parts by weight of ion exchanged water.
