[0092] Examples 1 to 6: Preparation of conductive thermoplastic resin composition

[0093] As additives, 20 parts by weight of glass fiber (183F, Owens Corning Corp., average length: 3 mm), 0.5 parts by weight of HDPE wax (HI-WAX 400P, MITSUI PETROCHEMICAL) and 0.5 parts by weight of antioxidant (Doverphos S-9228PC, DOVER CHEMICAL) was mixed with 100 parts by weight of the polycarbonate resin (A), followed by dry blending, thereby preparing a polycarbonate resin composition. Then, the prepared polycarbonate resin composition, conductive filler (B) and carbon fiber (C) are placed in the twin-screw extruder with side feeder (φ=45mm) with the amount listed in Table 1, then Treating at a nozzle temperature of 250° C. to 280° C., thereby preparing a conductive thermoplastic resin composition in the form of pellets. Here, the conductive filler (B) and carbon fibers (C) are introduced through a side feeder. The prepared pellets were dried at 100° C. for 3 hours, and then injection ...

Abstract

A conductive thermoplastic resin composition, according to the present invention, comprises a polycarbonate resin and a conductive filler, wherein the conductive filler comprises carbon nanotube-modified glass fibers and / or processed carbon nanotube-modified glass fibers. A conductive thermoplastic resin composition has excellent electrical conductivity, flame retardancy, and mechanical properties.

Description

technical field [0001] The present invention relates to a conductive thermoplastic resin composition. More specifically, the present invention relates to a conductive thermoplastic resin composition and a molded article comprising the same having excellent electrical conductivity, flame retardancy and mechanical properties. Background technique [0002] Polycarbonate resin has excellent processability and moldability, and is widely used in various household items, office equipment, electrical / electronic products, etc. There have been many attempts to make polycarbonate resins have electromagnetic shielding properties by imparting conductivity to polycarbonate resins, and to apply polycarbonate resins to automobiles, various electrical equipment, electric appliances such as TVs, electronic components and cables. [0003] Specifically, when the conductive panel and an exterior material formed of polycarbonate resin or the like are bonded together, electrostatic discharge may ...
