The invention discloses a preparation method of a polyetheretherketone composite material with high dimensional stability and antistatic property, comprising the following steps in sequence: S1 preparing the following raw materials in parts by mass: 50–80 parts of polyetheretherketone, 10–30 parts of conductive titanium dioxide, 3–20 parts of metal sulfide, 0.1–10 parts of processing auxiliary; S2 mixing the polyetheretherketone and the processing auxiliary in proportion in a rotary mixer, feeding from the main feeding port of a twin-screw extruder, feeding the conductive titanium dioxide and the metal sulfide from the side feeding port of the extruder via a feeder for melt mixing, extrusion and granulation; S3 in step S2, the rotary speed of the rotary mixer is 60–120 rpm, and the mixing time is 5–10 minutes. The invention adopts conductive titanium dioxide and metal sulfide to fill and blend PEEK. The spherical shape and good isotropy of titanium dioxide improve the warpage of the matrix. In addition, titanium dioxide has a whitening effect, which meets the appearance requirements of white parts.
