High-hardness wear-resistant waterborne polyurethane coating as well as preparation method and application thereof

The invention relates to a water-based functional coating, in particular to a high-hardness wear-resistant water-based polyurethane coating as well as a preparation method and application thereof. According to the invention, a specific substance is selected as a reaction monomer, and an organic silicon structure and an organic fluorine structure are introduced into a molecular structure, so that the organic fluorine-silicon modified hydroxy acrylic dispersion with high hardness and certain flexibility and stain resistance is prepared; then, the hydroxy acrylic resin is used as a main component, an isocyanate curing agent is selected as a curing agent, and the high-hardness wear-resistant two-component waterborne polyurethane coating is obtained. The waterborne polyurethane coating disclosed by the invention is green and environment-friendly, relatively high in hardness and good in wear resistance, has good adhesive force, scratch resistance, flexibility, stain resistance, flame retardance and the like, and ca
