PRE-COAT ALUMINUM ALLOY PLATE EXCELLENT IN HEAT RELEASING, ANTI-INJURY ABILITY AND ELECTRICAL CONDUCTIVITY

摘要

PROBLEM TO BE SOLVED: To provide a pre-coat aluminum alloy plate excellent in all of heat-releasing, anti-injury ability and electrical conductivity. SOLUTION: The plate comprises a substrate plate 2 composed of an aluminum alloy plate and pre-coat layers 3 and 4 formed on one or both surfaces of the substrate plate 2. At least one pre-coat layer 3 comprises a multi-layered coating film having two-layer structure, which is formed by laminating an under coating layer 31 comprising a first base resin 310 containing titanium oxide 311 and carbon black 312 to an upper coating layer 32 comprising the second base resin 320 into which granular synthetic resin beads 321 are dispersed. Preferably, the multi-layered coating film 3 is formed only on one surface of the substrate plate 2, and an electrical conductive film having single layer structure which comprises the third base resin 40 containing an electrical conductive material 41 is formed on the other surface of the substrate plate 2.
