[Prior Art] In the development of products in the field of electrical and electronic products, with the high pixelation and high-speed processing of digital cameras and digital cameras, the miniaturization of projectors, the high-speed processing of computers and mobile devices, and the LEDs of various light sources (Light Emitting Diode, light-emitting diodes, etc., have focused on heat dissipation measures. In the case of a miniaturized machine, the heat dissipation circuit is complicated. Therefore, it is required to integrate the resin case and the heat dissipation circuit, and it is excellent in thermal conductivity and is used as a casing. A resin material that is also excellent in mechanical strength. Further, in a small electronic device, the casing and the bottom plate are required to be thinned, and the flame retardancy of the thin-walled molded article is also required. It is known that a polycarbonate resin is used in the case of the above-mentioned electronic device, and the molded article including the polycarbonate resin composition is flame-retarded, and a gas-based flame retardant or a bromine-based flame retardant is added. It is a flame retardant. In addition, in recent years, it is safe to use the flame retardant method of the flame retardant containing no substances in the market from the viewpoint of environmental impact on the production, disposal, and incineration. In order to flame-retard the organophosphorus flame retardant which is the above-mentioned non-pyro-based flame retardant, in particular, the organic phosphate 151935.doc 201124470 compound is blended in the polycarbonate resin composition, it is necessary to mix a relatively large amount. Filling compound. The polycarbonate resin has a high molding temperature and a high melt viscosity, so that the molding temperature tends to be high. Therefore, the 'phosphorus ester compound generally contributes to the flame retardancy, but there are cases where the mold is corroded during the forming process, gas is generated, and the molding environment or the molded article is not necessarily sufficient. Therefore, it is required to obtain a flame retardant (especially a thin-walled flame retardant) of a desired molded article without using a halogen-based flame retardant such as a chlorine-based flame retardant or a bromine-based flame retardant or a phosphorus-based flame retardant. A polycarbonate resin composition excellent in thermal conductivity. A method of blending graphite is known as a method of imparting the heat dissipation property to a thermoplastic resin (see Patent Document 1 and Patent Document 2). Patent Document 1 discloses that a thermoplastic resin composition having less corrosiveness and excellent thermal conductivity can be obtained by blending a specific graphite with a thermoplastic resin. In order to improve the flame retardancy, it is preferred to use an organic tooth-based flame retardant or a phosphate-based flame retardant such as a halogenated carbonate oligomer or a halogenated epoxy compound, and it is not disclosed that a chlorine-based flame retardant is not used. , desert flame retardant and antimony flame retardant technology. Further, in Patent Document 2, the heat-dissipating casing accommodating the heat generating body has been described. The flame retardancy required for the casing of an electronic device or the like is not described, and % _ + i is required as needed. - The additive reveals a flame retardant such as an organic bromine-based flame retardant or a phosphorus-based I5, but does not disclose a technique of actively using a chlorine-based flame retardant, a bromine-based flame retardant, and a dish-based flame retardant. , X, it can be considered that, in its embodiment, since no flame retardant or anti-drip agent is added, it does not have the flame retardancy of 151935.doc 201124470. Further, a polycarbonate resin composition in which graphite is blended with a flame retardant to impart antistatic properties or conductivity to a polycarbonate resin is known (see Patent Document 3 and Patent Document 4). Patent Document 3 discloses an aromatic polycarbonate resin composition comprising a specific polyoxosiloxane compound in a formulation comprising an aromatic polycarbonate resin and graphite, and is equivalent to antistatic property and s Although the flame retardancy is not described, the technical content of obtaining a sufficient flame retardancy by a thin wall of about 1.5 mm required for a casing such as an electronic device is not described. Further, in Patent Document 4, as a technique of actively using no gas-based flame retardant, bromine-based flame retardant, and phosphorus-based flame retardant, polycarbonate resin, graphite, and organic sulfonic acid alkali (earth) are disclosed. In the flame retardancy evaluation of the metal salt, only the molded article having a thickness of 25 is evaluated, and as in Patent Document 3, it is required to be thin by about 1_5 mm required for a casing such as an electronic device. The wall does not have sufficient flame retardancy.

Artificial graphite, which is commonly used for carbon materials, can usually be produced by graphitization using petroleum coke or coal-based pitch coke as the main source. Further, in the present invention, artificial graphite is required instead of natural graphite because the flame retardancy of the thin wall can be obtained. The blending amount of the (Β) artificial graphite used in the present invention is 30 to 10 parts by mass, preferably 3 to 7 parts by mass, per 100 parts by mass of the above (4) polycarbonate resin. If it is less than 3 parts by mass, a sufficient thermal conductivity cannot be obtained, and (10) parts by mass does not provide thin-wall flame retardancy, and the impact strength is lowered, and the molecular weight at the time of granulation is lowered.

The above (C-3) ethylene single system is used to obtain a grafted organic compound containing polyorganotite. When the graft copolymer is blended in an aromatic polycarbonate resin to improve flame retardancy and impact resistance, the (C-3) vinyl monomer is also used for securing the composition. The compatibility of the branched copolymer with the aromatic polycarbonate resin allows the component of the graft copolymer to be uniformly dispersed in the aromatic polycarbonate resin. Therefore, as the (C-3) ethylene monomer, the ethylene compound is preferred.
