METHOD FOR TREATING NANO-SIZED SURFACE MODIFICATION ON ALUMINUM FOR OPC DRUM AND ALUMINUM TUBE FOR OPC DRUM MANUFACTURED BY THE METHOD

摘要

The present invention relates to a method for the nano- surface modification of an aluminum base layer for OPC drums, and more particularly a method for performing the dry modification of an aluminum alloy for drums, such that the method does not cause fine black spots, and the aluminum alloy has a base layer having excellent wettability with an organic photo-conductor (OPC) to be coated thereon. According to one aspect, the method for the nano-surface modification of the aluminum base layer comprises the steps of: preparing a mirror-surface-treated aluminum tube; and dipping the prepared aluminum tube in an alkaline aqueous solution to form aluminum hydroxide on the surface layer thereof. According to the inventive method for the nano-surface modification of the aluminum base layer for OPC drums, a uniform insulating layer can be formed on the surface of the aluminum base layer through simple treatment at low cost while minimizing an environmental problem.
