Title:
PRECOATED ALUMINUM ALLOY PLATE FOR HEAT DISSIPATION MEMBERS, AND HEAT DISSIPATION MEMBER USING SAME
Document Type and Number:
WIPO Patent Application WO/2012/169569
Kind Code:
A1
Abstract:
A precoated aluminum alloy plate (1) for heat dissipation members, which comprises an aluminum alloy plate (10), a first coating film (11) that is formed on one surface of the aluminum alloy plate (10), and a second coating film (12) that is formed on the other surface of the aluminum alloy plate (10); and a heat dissipation member (5) which uses the precoated aluminum alloy plate (1). The coating film (11) has heat dissipation properties more excellent than those of the surface of the aluminum alloy plate (10); and the second coating film (12) has a bonding function of forming an adhesive by being melted or softened when heated. The first coating film (11) may have a configuration which is achieved by having a first base resin contain a heat dissipating substance, said first base resin having a softening point higher than 150˚C and being composed of at least one resin that is selected from among urethane resins, polyolefin resins, epoxy resins, fluororesins and polyester resins.
