COATING METHOD OF PORCELAIN INSULATORS METAL FITTING AND PORCELAIN INSULATOR MANUFACTURED BY THEREOF

摘要

The present invention relates to a method of coating metal fittings for preventing deterioration of performance of magnetic insulators and improving light reflectance, and magnetic insulators manufactured by the same, and more particularly, methyltriethoxysilane (CH 3 Si (OC 2 ) H 5 ) 3 ), ethanol, hydrochloric acid and water to prepare a methyl silicone solution by mixing in a certain ratio, magnesium acetate (Mg(CH 3 COO) 2 ), hydrofluoric acid (HF), anhydrous ethanol and ethanol in a certain ratio Mixing to prepare a MgF 2 solution, preparing a coating solution by mixing the methyl silicone solution and the MgF 2 solution, and coating the coating solution on the surface of a metal fitting of a magnetic insulator having a zinc (Zn) coating film to form MgF 2MgF 2 on the zinc coating film through a coating method including a coating step of forming a coating filmBy additionally double coating the coating film, it prevents the formation of a natural oxide film and improves light reflectance.
