Inventor: TAKEMURA KENJI
IPC: H01Q15/24
Filed: 1984-02-10
Abstract: PURPOSE:To obtain the titled reflecting plate having the reflecting performance of radio waves for a long period of time by using a lamination structure of a thermoplastic resin layer excelling in weather resistance, a metallic foil which reflects radio waves and an olefin polymer layer containing an inorganic filler which functions as a structure matter. CONSTITUTION:A dry lamination process is applied to laminate a thermoplastic resin layer A and an olefin polymer layer C to a metallic foil B. Then the layer B of the laminated foil B is attached to the mobile side of a metallic mode of an injection molding machine with the layer C set to the metallic mold side of the fixed side. Then the metallic mold is closed. An olefin polymer D containing an inorganic filler is injection-molded to obtain a reflecting plate. In this case, the injection molding temperature is set higher than the melting point of the olefin polymer containing the inorganic filler and also lower than the thermal decomposition temperature of said olefin polymer. Furthermore either one or both of two primer layers (a) and (b) are not added.
