The invention relates to an anti-static caster special raw material and a method for preparing the anti-static caster. The special raw material comprise 100 portions of polyurethane, 22 to 28 portions of reinforcing agents, 8 to 12 portions of conductive agents, 0.3 to 0.5 portions of lubricants, 8 to 14 portions of elastomers, and 0.3 to 0.7 portions of antioxidant. The anti-static caster can beprepared by adopting an extruder to extrude or an injection molding machine to inject. Compared with the prior anti-static caster, the anti-static caster of the invention is simple in formulation andeasy to obtain raw material, the caster has the characteristics of good processing stability, simple processing, low equipment requirement, convenient controlling, stable quantity, and the like; and the anti-static caster resists impacting and wearing, and has the advantages of certain rigidity and flexibility, the material is environment-friendly, and the comprehesive property is good.
