Title:
The manufacturing method of aluminum foil, and aluminum foil
Document Type and Number:
Japanese Patent JP5979117
Kind Code:
B2
Abstract:
An obj ect of the present invention is to provide a method for producing a high-ductility, high-purity aluminum foil at a high film formation rate by electrolysis using a plating solution having a low chlorine concentration. A method for producing an aluminum foil of the present invention as a means for achieving the object is characterized in that an aluminum film is formed on a surface of a substrate by electrolysis using a plating solution at least containing (1) a dialkyl sulfone, (2) an aluminum halide, and (3) at least one nitrogen-containing compound selected from the group consisting of an ammonium halide, a hydrogen halide salt of a primary amine, a hydrogen halide salt of a secondary amine, a hydrogen halide salt of a tertiary amine, and a quaternary ammonium salt represented by a general formula: R 1 R 2 R 3 R 4 N·X (wherein R 1 to R 4 independently represent an alkyl group and X represents a counteranion for the quaternary ammonium cation), and then the film is removed from the substrate.
