Abstract
The invention relates to a color electrophoretic coating process of aluminum alloy sections. The process mainly comprises the steps of blank preparation, arrangement, degreasing, water washing, alkali corrosion, water washing, neutralization, water washing, oxidation, water washing, electrophoresis, draining and solidification. Compared with the traditional process of electrophoretic coating after electrolytic coloring and hole sealing, the color electrophoretic coating process reduces the electrolytic coloring, the hole sealing and twice water washing procedures, so that no heavy metal ions or nickel ions are emitted, the water consumption is largely decreased, and the purposes of energy conservation and environmental protection are preferably realized.
