Resin solution excellent in workability, solution stability and blackening after processing and manufacturing method of resin coated steel sheet using same

摘要

The present invention relates to a resin solution for an anti-fingerprint steel sheet applied to a chromate-treated electro zinc plate and a method for producing a resin coated steel sheet using the same; The purpose is to provide a resin solution capable of ensuring the processability of the steel sheet after being coated on the steel sheet with the workability and stability of the resin solution for the steel plate, and a method for producing a resin coated steel sheet using the same.;The present invention for achieving the above object, the epoxy resin having a molecular weight of 900 to less than 1500 to the silica-modified ethylene-acrylic resin solution: a first resin solution containing 3-5phr; And a second resin solution containing 2-20 phr of fluorine or fluoroethylene wax in the first resin solution. Then, using the first resin solution or the second resin solution on the chromate-treated electrogalvanized steel sheet so that the dry film thickness is 0.5-3.0㎛, the coated steel sheet is baked at 80-180 ° C. The summary relates to a method for producing a resin coated steel sheet.
