PURPOSE:To enhance the transmission blocking rate of infrared rays by molding a transparent or translucent synthetic resin containing a SnO2 fine powder in a dispersed state into a shape of every kind to form an infrared ray absorbable synthetic resin molded product. CONSTITUTION:A transparent synthetic resin containing a SnO2 fine powder in a dispersed state is molded into a sheet or film which is, in turn, bonded to and integrated with a transparent synthetic resin substrate to obtain an infrared ray absorbable synthetic molded product. Concretely, the synthetic resin sheet composed of an acrylic resin having the SnO2 fine powder uniformly dispersed therein is laminated to and integrated with the single surface of a transparent synthetic resin plate 2 composed of a polycarbonate resin to mold a synthetic resin plate. Further, as another mode, the SnO2 fine powder is mixed with the transparent or translucent synthetic resin composed of the polycarbonate resin and dispersed in a thickness direction uniformly to mold the synthetic resin sheet 1. |
