Galvalume colored transparent CREE coated steel sheet and its manufacturing method

摘要

The present invention is a galvalume-colored transparent which can improve the corrosion resistance and the workability and chemical resistance of the existing water-soluble galvalume-colored steel sheet in the manufacturing technology of the colored transparent crust-coated steel sheet whose base steel sheet is galvalume steel sheet (zinc-55% aluminum). The present invention relates to a cree coated steel sheet and a method of manufacturing the same, wherein the linear polyester resin is 33 to 40% on the surface of any one of hot-dip galvanized steel sheet, galvalume-plated steel sheet, and aluminum steel sheet, and less than 1% of color pigment and 3 to 5% of melamine resin. , Primer of 3-10% epoxy resin, 15-20% ester solvent, 30-40% aromatic hydrocarbon solvent, 1-2% slim additive, 1-2% other additives The top coat is coated without coating, and the drying temperature of the steel sheet is 210 to 240 ° C., and the coating amount is formed to be in the range of 3 to 20 μm.
