Abstract
The invention discloses a method for preparing an anti-electrostatic property modified plastic raw material. The method comprises the following steps: (A) cleaning wastes: putting plastic wastes and a mixture, which is prepared from polyethersulfone and polyetherimide through mixing according to the mass ratio of 4: 1, into a pickling tank, soaking for 2 days, then, fishing out and air-drying; (B) crushing the air-dried wastes, heating to melt the wastes, adding ABS (Acrylonitrile-Butadiene-Styrene copolymer), brucite powder, chloromethane, graphite, a nonionic surfactant, benzophenone and a conductive agent, and enabling the raw material to be viscous; (C) extruding the viscous raw material obtained in the step (B) with an extruder, so as to form strips, arranging a cutter in front of the extruder, cutting the strips once every 1mm, so as to form small strips, and enabling the cut small strips to fall onto a water-cooled conveying belt; (D) cooling the small strips by the water-cooled conveying belt during conveying, and bagging until the small strips are conveyed to the tail end, thereby obtaining anti-electrostatic property modified plastic raw material granules, wherein the melting temperature is 180-300 DEG C, and the conveying degree of the water-cooled conveying belt is 8-10 meters. The method is simple in preparation, convenient in use and high in waste utilization ratio.
