STEEL PLATE FOR CONTAINERS AND MANUFACTURING METHOD FOR SAME

WIPO Patent Application WO/2012/036199

A1

The purpose of the present invention is to provide a manufacturing method for steel plates for containers that produces steel plates with excellent film adhesion qualities. This steel plate for containers has, on a steel plate, a chemical conversion coating with a metal Zr content of 1-100mg/m2, a P content of 0.1-50mg/m2, and an F content of no more than 0.1mg/m2, upon which is formed a phenol resin layer with a C content of 0.1-50mg/m2. Moreover, the manufacturing method for steel plates for containers is a method for obtaining the steel plate for containers wherein the chemical conversion coating is formed on the steel plate by immersion or electrolytic treatment in a treatment solution containing Zr ions, phosphoric acid ions, and F ions; and subsequently, the steel plate upon which said chemical conversion coating has been formed is immersed in, or undergoes topical application of, an aqueous solution containing phenol resin, and is then dried.
