Document Type and Number:
WIPO Patent Application WO/2011/104928
Kind Code:
A1
Abstract:
Provided is a conductive precoated aluminum alloy sheet (1) which comprises a substrate (2) formed from an aluminum alloy sheet, a chemical conversion film (3) formed on one or both surfaces of the substrate (2), and a resin coating (4) formed on the chemical conversion film (3). The resin coating (4) comprises, at a specific mixture ratio, a urethane resin having a glass transition point of 100ºC to 150ºC, a colloidal silica having a primary particle diameter of 5 to 80 nm, and an inner wax having a primary particle diameter of 0.05 to 5 µm and a molecular weight of 1,000 to 16,000. Thickness (T) of the resin coating (4) is 0.05 to 1.0 µm, and surface roughness (Ra) of the substrate (2) is 0.1 to 0.8 µm. Furthermore, T/Ra is 0.07 to 4.0.
