This invention relates to the field of coatings, specifically to a wear-resistant, formaldehyde-removing artistic coating and its preparation method. The coating, by weight, comprises: 45-55 parts of waterborne polyurethane-modified acrylic emulsion, 15-25 parts of silane-modified filler, 4-8 parts of supported formaldehyde-removing filler, 6-12 parts of pigment, 0.2-0.6 parts of dispersant, 0.1-0.4 parts of defoamer, 0.3-0.8 parts of thickener, 1-3 parts of film-forming aid, and 15-25 parts of deionized water. This invention achieves a balance between film hardness and toughness by using waterborne polyurethane-modified acrylic emulsion as the film-forming substance and combining it with silane-modified filler. The polyurethane segments provide excellent flexibility and resilience, the acrylic segments provide high hardness, and the silane-modified filler forms a strong chemical bond with the resin matrix through a silane coupling agent, improving the overall performance of the coating and extending its service life.
