The invention discloses a water-based industrial artistic coating and a preparation method thereof. The artistic coating is prepared from water, a dispersant, GN-90, a wetting agent, a neutralizer, thixotropic resin, titanium dioxide, filling powder, water-based acrylic resin emulsion, water-based epoxy resin emulsion, a thickener, a defoamer, a film-forming agent, a water-based colorant and the like. The water-based industrial artistic coating disclosed by the invention has ultralow VOC (Volatile Organic Compounds) content, does not contain benzene and free heavy metals, and has no fire potential safety hazard in production, transportation, machining and storage. In the invention, proportion solid content is high, a unit coating area is large, and unit cost is low. In addition, the coating further has the advantages of high hardness, scratch resistance, high drying speed, simplicity and convenience for operation, small use amount, high efficiency, firm surface pattern, excellent protective decorative effect and the like, and the gap of the water-based industrial artistic coating is filled in.
