The invention discloses a quick self-drying type spraying UV (ultraviolet) paint. The quick self-drying type spraying UV paint is prepared by mixing the following raw materials of 10 to 80 parts of polyurethane modified acrylate resin emulsion, 0.1 to 3 parts of emulsifier, 0.1 to 3 parts of defoamer, 0.1 to 2 parts of matting agent, 0.1 to 2 parts of accelerant, 1 to 8 parts of filming additive,0.1 to 3 parts of wetting agent, 0.1 to 3 parts of dispersant, 0.1 to 3 parts of thickener, 0.1 to 1 part of photo-initiator, 8 to 15 parts of pigment, 200 parts of deionized water, and 10 to 50 partsof co-solvent. The invention also provides a preparation method of the quick self-drying type spraying UV paint. The quick self-drying type spraying UV paint has the advantages that the hardness is improved under the condition of adding a small amount of photo-imitator, so that the hidden hazard of pollution to environment is reduced, and the production cost is reduced; by adding a certain amountof initiator, the drying speed of a paint film is accelerated, the quick filming effect is realized, and the heat-resistant property of the UV paint is improved; the content of organic solvent is low, and the environment-friendly property is higher.
