Kind Code:
B2
Abstract:
PURPOSE:To enhance bonding properties and corrion-resistant properties by etching an aluminium or a aluminum alloy surface of a sheet on which aluminum or aluminum alloy and stainless are clad and covering the same with specified fluorine resin. CONSTITUTION:An aluminum or aluminum alloy surface of a sheet on which aluminum or aluminum alloy and stainless are clad is etched, over which fluorine resin, containing 0.5 wt. % or more to 10 wt. % or less of heat-resistant high moleculars such as polyamide image, polyimide, polyphenylene sulfide or polyethel sulfoine or a mixture of them to be used as a filler, is clad. Bonding force is enhanced by mixing the filler with the fluorine resin even for a material of poor etching properties. When said filling quantity is less than 0.5 wt. %, bonding force is not enhanced sufficiently and corrosion-resistant properties are not enhanced, either. When more than 10 wt. % is mixed in, stretching of a film is insufficient, although bonding properties is further enhanced, and local breakage of the film is generated during the press molding and corrosion-resistant properties and the like are lowered.
