Field of the Invention The present invention relates to a flame-retardant reinforced polyethylene terephthalate resin composition that has excellent thermal stability during molding, heat discoloration resistance, and light discoloration resistance. Flame-retardant reinforced polyethylene terephthalate resin is used for lighting equipment, and for this purpose, in addition to strength, rigidity, and heat resistance, it is also required to have little thermal discoloration and light discoloration. If parts of fluorescent lamps or mercury lamps suffer from significant thermal discoloration or photodiscoloration, they will look bad and have no commercial value. The flame-retardant reinforced polyethylene terephthalate resin of the present invention has excellent heat discoloration resistance and light discoloration resistance, and is therefore used as parts of fluorescent lamps and mercury lamps.

This is a composition consisting of 0.9 parts by weight of a mold release agent. To this composition, brominated polycarbonate oligomer, brominated polystyrene, benzotriazole compound, phosphorus compound, hindered amine compound, hindered phenol compound, etc. were added to the compositions shown in Tables 1 and 2, respectively. It was blended. Injection molded products are made by drying pellets of flame-retardant reinforced polyethylene terephthalate resin composition in a dehumidifying dryer.
After drying at 30°C for 4 hours, it was molded into a dumbbell test piece using a 1-ounce injection molding machine at a molding temperature of 275°C and a mold temperature of 90°C.
