(57) [Summary] [Object] The present invention provides a method for producing a non-film-removing type lubricating steel sheet which can be deep-drawn and bent without applying a press oil and can be used as a corrosion-resistant coating. [Structure] Chromate treatment of 5-100 milligrams per square meter of chromium on the surface of plated steel sheet as chromium is performed, and 10-40% of bisphenol skeleton, ester skeleton, carboxyl group-containing ether ester type urethane resin and epoxy resin Silica, 3 to 30% of a polyolefin wax coating containing 0.2 to 5 μm And a baking process at a plate temperature of 80 to 200 ° C. [Effect] It can be pressed without using CFCs and triethane, and can be used as a corrosion-resistant coating. Since it does not contain organic solvents, it can be manufactured with existing plating lines. |
