The floor white-mark resistant UV paint is composed of a prime paint and a surface paint. The prime paint is composed of polyurethane acrylate (PUA) resin, epoxy acrylate resin, light-cured monomers, and a photosensitizer and is prepared by evenly mixing all the components mentioned above. The surface paint is composed of polyurethane acrylate (PUA) resin, light-cured monomers, a matting agent, a photosensitizer, a dispersant, and a defoaming agent, and is prepared by the following steps: adding PUA resin, 20 to 30% of light-cured monomers, a dispersant, and a defoaming agent into a reactor at first, dispersing for 0.5 hour, then adding a matting agent into the reactor, dispersing for 2 hours, finally adding the residual light-cured monomers and a photosensitizer into the reactor, dispersing for 0.5 hour, and evenly mixing so as to obtain the surface paint. The prime paint and the surface paint are used as a combination, the paint is not easily scratched by hard objects, the paint color will not fade, the scratches formed by sharp things can be wiped off, and the paint also has the advantages of durability and beautiful and elegant appearance.
