COVER FOR EXOTHERMIC ARTICLE EXCELLENT IN HEAT ABSORBING PROPERTY AND SURFACE TREATED METAL SHEET THEREFOR, AND APPLICATIONS THEREOF

摘要

A cover for an exothermic article excellent in heat absorbing property made from a metal/a non-metal, which comprises a cover base material and, formed at least on the inner surface thereof, a heat absorbing coating layer exhibiting a total thermal emissivity in the region of the wave length of 600 to 3000 cm<-1> of 0.70 or more as measured at a temperature of 80 to 200°C; a surface treated metal sheet excellent in heat absorbing property and electroconductivity which comprises a metal sheet/a plated metal sheet, formed at least one surface thereof, the above heat absorbing coating layer comprising (a) 100 mass % of solids in a binder, (b) 10 to 150 mass % of a heat absorbing pigment (and optionally (c) 1 to 150 mass % of an electroconductive pigment); a refrigerator excellent in heat efficiency having an inside surface of its outer metal sheet coated with the above heat absorbing film; an portable or on-vehicle device with exothermic electronic parts which has a case and, formed on the inside thereof, a heat absorbing coating layer comprising 100 parts by mass of solids in a binder, 1 to 20 parts by mass of a carbon having a particle diameter of less than 0.1 mum and 1 to 140 mass % of a carbon having a particle diameter of 0.1 to 50 mum, with the proviso that the sum of the amounts of the two types of carbon is 10 to 150 parts.
