Printer shell material and preparation method thereof

The invention relates to a printer shell material and a preparation method thereof, and relates to the technical field of printing equipment. The printer shell material includes the following components in percentage by mass: 97-99.5% of polystyrene resin and 0.5-3% of an additive, wherein the additive includes 72-86% of a toner and 14-28% of a dispersant, and the dispersant includes magnesium stearate and zinc stearate. The preparation method specifically includes the following steps that S1, titanium dioxide, titanium yellow, anthraquinone, carbon powder, ferric oxide, light calcium carbonate, magnesium stearate and zinc stearate are mixed thoroughly and evenly to prepare the additive; S2, the polystyrene resin and the additive are mixed in a mixing tank for 10 minutes to prepare a premix; S3, the premix in the S2 is sent to a screw extruder for blending extrusion, wherein the rotating speed of a screw is 400+/-40rpm to obtain an extrudate; and S4, the extrudate is cooled, granulatedand sieved to prepare th
