Environment-friendly art coating and preparation method thereof

The invention relates to the technical field of art coatings, in particular to an environment-friendly art coating and a preparation method thereof.The environment-friendly art coating is prepared from, by weight, emulsion, sodium hexametaphosphate, sand flour, filler, a silane coupling agent, lignocellulose, a water-based dispersing agent, a water-based wetting agent, a water-based defoaming agent, a thickening agent and water. The filler with low oil absorption and good stability is added into the artistic coating to serve as powder for supporting artistic modeling, then the silane coupling agent and the lignocellulose are added in a matched mode, under the combined action of the raw materials, the bonding performance of the whole coating system is improved, the coating is endowed with certain flexibility, bottom surface treatment is not needed, thin coating can be achieved, and the service life of the coating is prolonged. The problem of coating cracking caused by different thicknesses without undersurface
