Antistatic PVC coating material for surface treatment and preparation method thereof

The invention relates to the field of antistatic coating materials, and particularly discloses an antistatic PVC coating material for surface treatment and a preparation method thereof.The antistatic PVC coating material for surface treatment is prepared from, by weight, 30-45% of polyvinyl alcohol solution, 4-9% of filler, 0.1-0.3% of coupling agent and the balance antistatic treating agent; the antistatic treating agent comprises lithium trifluoromethanesulfonimide, cellulose acetate and a reinforcing agent. The preparation method comprises the following steps: preparing an antistatic treating agent: dissolving lithium trifluoromethanesulfonimide and cellulose acetate in a solvent, adding a reinforcing agent, and uniformly mixing to obtain the antistatic treating agent; and blending: uniformly mixing the polyvinyl alcohol solution, the filler, the coupling agent and the antistatic treating agent. The prepared coating material can be directly coated on the surface of a PVC material product to form a transpar
