PRECOATED ALUMINUM ALLOY PLATE EXCELLENT IN RADIATION PROPERTIES, SCRATCH RESISTANCE AND CONDUCTIVITY

摘要

PPROBLEM TO BE SOLVED: To provide a double-side precoated aluminum alloy plate excellent in press moldability and radiation properties. PSOLUTION: The precoated aluminum alloy plate is composed of: a substrate 10 comprising an Al-Mg-Cu type aluminum alloy plate; the lubricating coating film 2 formed on one side of the substrate 10; and the radiant coating film 3 formed on the other surface of the substrate 10. The lubricating coating film 2 is formed by coating one side of the substrate 10 with a first organic resin coating containing inner wax and curing the coating layer on the substrate 10. The radiant coating film 3 is formed by coating the other side of the substrate 10 with a second organic resin coating containing a radiant substance 35, which comprises at least one kind of a substance among titanium oxide, carbon black, silica and zirconium oxide, and by curing the coating layer on the substrate 10. It is preferable to add at least one kind of the radiant substance among titanium oxide, carbon black, silica and zirconium oxide to the lubricating coating film 2. PCOPYRIGHT: (C)2007,JPO&INPIT
