Abstract

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.

Description

technical field [0001] The invention relates to the technical field of UV curable coatings for woodware, in particular to a floor anti-white mark UV coating that can be used for wooden floors. Background technique [0002] UV-curable coatings have anti-pollution and energy-saving effects, excellent chemical and physical properties of coating, and fast curing characteristics, and are widely used in many fields. Among them, the use in the field of wooden flooring is considered to be an efficient and environmentally friendly interior decoration solution. [0003] Generally speaking, although UV-coated floors have the characteristics of high hardness, high wear resistance, and durability, the surface paint film will be damaged due to daily wear and tear after long-term use of the floor painted by the traditional UV coating process. , this kind of damage will lead to uneven gloss on the floor surface, and the floor under this coating process will leave some white scratches or sc...
