HEAT RADIATION SHEET FOR FLOOR HEATING DEVICE, AND FLOOR HEATING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a heat radiation sheet capable of improving efficiency and durability of a floor heating device.;SOLUTION: A heat radiation sheet 9 includes an aluminum foil 9a, and an adhesive layer 9b disposed on the aluminum foil, the adhesive layer includes 100 pts.mass of an acrylic adhesive, and 1-20 pts.mass of an inorganic oxide filler including ≥50 mass% of alumina, a weight-average molecular weight Mw of the acrylic adhesive is 400,000-800,000, a ratio Mw/Mn of the weight-average molecular weight Mw and number-average molecular weight Nm is ≤5, and the inorganic oxide filler in the adhesive layer has a volume average particle size measured by a laser diffraction/scattering method, of 0.3-10 μm.;COPYRIGHT: (C)2013,JPO&INPIT
