The invention discloses a preparation method of a novel antibacterial and antifungal polyurethane paint film based on N-alkyl glycol amines. The steps are: dissolving N-alkyl glycol amines and halogenated alkanes in ethanol and heating React for 12h to 72h at Celsius, precipitate with a precipitant, and dry in vacuo to obtain a dihydroxyquaternary ammonium salt. Mix the dihydroxyquaternary ammonium salt with 2-ethyl-1,3-hexanediol, butyl acetate, and dilauric acid Dibutyltin is mixed, and ultrasonically stirred evenly, and the resulting solution is heated to 50-60°C under the protection of an inert gas; 1,6-hexamethylene diisocyanate and butyl acetate are added to the above solution, heated to 60-80°C, and reacted After 5-7 hours, the antibacterial polyurethane coating is obtained; the obtained polyurethane coating is brushed on the surface of the substrate, and dried naturally to form a film. The preparation method of the invention is simple, easy to operate, safe and environment-friendly, suitable for industrial production, and the coating has good anti-bacteria and mold performance.
