ELECTROCONDUCTIVE THERMOPLASTIC RESIN

In a tumbler and the like, polypropylene pellets are blended with 1 to 5 wt % of carbon nanotubes, 10 to 30 wt % of fly ash, 10 to 20 wt % of talc and 0.3 to 1 wt % of a modifier, the resulting blend is extruded from a screw extruder while heating the blend to a melting temperature of about 160 to 260° C., to generate a strand. This strand is cooled and cut into pellets having a predetermined length. Owing to blending with fly ash, talc and a modifier, an inexpensive lightweight electroconductive thermoplastic resin excellent in dust-proofness, heat resistance and recyclability is obtained, even if the blending amount of carbon nanotubes is small. 1. An electroconductive thermoplastic resin characterized in that a crystalline thermoplastic resin is blended with 1 to 2 wt % of carbon nanotubes , 5 to 30 wt % of carbon fiber , 10 to 30 wt % of coal ash generated in a powdered coal combustion boiler , 10 to 20 wt % of an inorganic filler , and 0.3 to 1 wt % of a modifier ,wherein the inorganic filler is at least one selected from the group consisting of talc, calcium silicate, aluminum silicate, bentonite, zeolite, basic magnesium carbonate, volcanic ash, natural gypsum, attapulgite, quartz powder, kaolin clay, pyrophyllite clay, cerussite, dolomite powder, mica, calcium sulfate, silicon carbide powder, magnesium oxide, titanium oxide, precipitated barium sulfate, and barite.2.
