[0162] (I) Evaluation items

[0163] (I-1) Surface resistivity

[0164] Under conditions of a cylinder temperature of 300°C, a mold temperature of 80°C, an injection speed of 20mm / sec, and a molding cycle of about 60 seconds, a gusset of width 45mm×length 80mm×thickness 2mm was molded by injection molding. Take out the molded products of the 2nd, 4th, 6th, 8th and 10th times after washing, and place them for 24 hours in an environment with a temperature of 23°C and a relative humidity of 50%, and use an electronic insulation meter (Toa Denpa Kogyo Co., Ltd. Co., Ltd.) and a resistance meter (Mitsubishi Chemical Co., Ltd.), the surface resistivity of the five gussets was measured, and the average value was calculated. Additionally, 1.0×10 14 A surface resistivity of Ω or less was set as good.

Abstract

The purposes of the present invention is providing a electroconductivity polycarbonate composition which is provided with high conductivity, and providing deformation characteristic to obtain improved product. The present invention provides a electroconductive resin composition, which is characterized in that, polycarbonate resin (A ingredient ) relative to 100 weight portion, containing 0.1-15 wt% electroconductivity carbon compounds (B ingredient ) and 0.01-1 wt% ache modified polyolefins genus wax (C ingredient ).

Description

technical field [0001] The present invention relates to a conductive resin composition containing polycarbonate resin and conductive carbon compound. More specifically, the present invention relates to a resin composition superior in electrical conductivity without impairing the good deformation properties of polycarbonate resins. Background technique [0002] As for composite materials containing conductive carbon compounds and thermoplastic resins, many composite materials have been developed, and some of them have been put into practical use. Polycarbonate resins are also included in the thermoplastic resins. In particular, composite materials containing carbon nanotubes (carbon nanotubes), which are conductive carbon compounds, are characterized by less contamination by particles, less outgassing, good surface finish and gloss, good fluidity, and less warpage. , good recyclability and the ability to maintain the physical properties of the resin material (please refer t...
