RESIN COATING ALUMINUM MATERIAL FOR HARD DISK DRIVE CASE, HARD DISK/DRIVE CASE USING THE RESIN COATING ALUMINUM MATERIAL AND HARD DISK DRIVING DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a resin coating aluminum material for hard disk case drive which is light in weight and is excellent in a molding workability and does not gener ate gas from resin coating films under a more strict use condition and moreover to provide a lightweight hard disk drive case having high corrosion resistance of material in which this resin coating aluminum material is used and the risk of a malfunction and a failure due to the generating of gas from organic resin coating films is not present and a hard disk driving device in which this hard disk drive case is used. SOLUTION: This resin coating aluminum material is constituted by forming a coating film which is to be formed with a coating compound in which a polyester resin having a hydroxyl group, an aminoplast resin and an epoxy resin are contained and whose thickness is equal to or thicker than 1μm as a first layer on the primary coating film of the one side of an aluminum alloy plate on which a primary coating film is formed and by forming a coating film which is to be formed with a coating compound in which the polyester resin having the hydroxyl group and the aminoplast resin are contained and whose thickness is equal to or thicker than 5μm as a second layer on the first layer.
