PROBLEM TO BE SOLVED: To provide a polycarbonate resin composition that has high flame retardance at small thickness, has sufficient surface hardness requiring no hard coat layer, generates little gas at molding, is excellent in heat resistance, shelf stability and recycleability and is free of bromine and phosphorus acid flame retardants, and a molded product thereof. SOLUTION: The polycarbonate resin composition essentially comprises a resin material comprising: 85-95 mass% aromatic polycarbonate resin having a weight average molecular weight of 37,000-55,000 calculated in terms of polystyrene; and 15-5 mass% polystyrene resin free of rubber components. The resin composition may optionally contain resin components other than ones derived from recycled raw materials as far as they do not deteriorate characteristics of the resin composition. A polyfluoroolefin resin, an organic sulfonate flame retardant and a silicon flame retardant are added to the resin material. The aromatic polycarbonate resin composition is molded into a prescribed shape. COPYRIGHT: (C)2010,JPO&INPIT |
