HEAT RADIATION REFLECTING LAMINATED SHEET

摘要

PURPOSE:To obtain a heat radiation reflecting laminated sheet hardly feeling color in the appearance by reflection light by forming a transparent oxide layer in a heat radiation reflection film put between either one transparent glass sheet and a transparent resin film from the laminate having a low reflection index layer and a high reflection index layer. CONSTITUTION:A heat radiation reflecting film 2 and a transparent resin 3 are thermally fused as shown in the figure between the first and second transpar ent glass sheets 1 and 4 to form a heat radiation reflecting laminated sheet. Then a reflecting film 2 is coated with a first layer 7a which laminates films 5a and 6a of a transparent metal oxide each being 1.6-2.0 and 2.3-2.4 in reflection index on a glass plate 1. A second layer 8a of Ag is applied thereon and a third layer 7b which laminates films 5b and 6b of the transparent metal oxide each having prescribed reflection index is applied thereon. Then a fifth layer 7c consisting of the transparent oxide is further applied on the layer 7b. As a result, the resultant heat radiation reflecting laminatd sheet reduces solar radiation energy which enters into the inside of the laminated sheet without impairing color feeling of vehicle and can suppress increase of temperature of the inside (interior).
