▎ 摘　　要

NOVELTY - An antistatic aqueous polyurethane coating material comprises aqueous polyurethane solution, water-dispersible inorganic nano-filler, and water-dispersible conductive organic filler. The mass ratio of aqueous -based polyurethane, aqueous -dispersible inorganic nanometer filler, and water-dispersible conductive organic filler is 100:0.1-5:0.1-5. USE - Antistatic aqueous polyurethane coating material. ADVANTAGE - The antistatic aqueous polyurethane coating material has high tensile strength, high mechanical property, high strength, and good antistatically performance, and improves the conductivity and mechanical property of the coating material. The coating material is easy to disperse, and easy to form film, so that it is necessary to select the proper solid content range. The solid content of the water-dispersible conductive organic filler is 70-90 (preferably 80-85)% and the total water amount of the mixed solution of water dispersible inorganic nano-filler is 10-25% to cause agglomeration, and the solid content is too high to form a film, thus it is not easy to select a proper solid range. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing antistatic aqueous polyurethane coating material, which involves uniformly mixing the raw materials according to the proportion, defoaming, drying to obtain the antistatic aqueous polyurethane coating material.
