METHOD FOR MANUFACTURING COLORED ALUMINUM PRODUCT WITHOUT DEGRADING CHROMATICITY OR COLORED ALUMINUM ALLOY PRODUCT, COLOR COMPOSITION FOR COLORING AND THE COLORED ALUMINUM PRODUCT, OR COLORED ALUMINUM ALLOY PRODUCT

摘要

PURPOSE: A method for manufacturing colored aluminum product without degrading chromaticity or colored aluminum alloy product, color composition for coloring and the colored aluminum product, or colored aluminum alloy product are provided to obtain predetermined color comparing with aluminum before coloring or a material made of aluminum alloy and to improve thermal resistance.;CONSTITUTION: A method for manufacturing colored aluminum product or colored aluminum alloy product comprises: a step of processing a material made of aluminum or aluminum alloy with anodic oxidation process among process solution containing phosphoric acid and forming an anodic oxidation film including a plurality of air holes on a surface of the material; a step of processing the material with hot water at 40-100 deg. C; and a step of dipping the material among color composition for coloring containing color particle, dispersing agent, and water and coloring by filling the color particle into the air holes existing to the anodic oxidation film.;COPYRIGHT KIPO 2013
