Problems solved by technology

[0009] The self-drying paint currently used in the market contains a large amount of organic solvents. The addition of a large amount of organic solvents is not conducive to environmental protection and human health, and a certain amount of preservatives are added to the self-drying paint produced to prevent deterioration. Addition will affect the quality of the paint to a certain extent
[0010] For example, Chinese patent 2016109891424 discloses a special self-drying paint for water-based auto parts. The self-drying paint has good gloss, plump paint film, high hardness, and good salt spray resistance; A large amount of preservatives, the addition of preservatives will affect the stability of the paint to a certain extent, making the paint layered in a short time, affecting the use

Abstract

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.

Description

technical field [0001] The invention belongs to the field of chemical industry, in particular to a fast self-drying UV paint for spraying and a preparation method thereof. technical background [0002] The long-term use of paints in furniture, building materials and woodware industries is mainly traditional solvent-based paints. Solvent-based paints have a relatively strong odor and take a long time to dry; traditional solvent-based paints are applied by spraying, and the coating film is thin and the utilization rate of paint is low. Only 50% of the paint can be used. rate, the rest of the sprayed paint cannot cover the surface of the workpiece, and it needs multiple coatings and coatings to achieve the effect; the efficiency is low, the cost is high, the environment is polluted, and the health of the construction personnel is affected; and the traditional solvent-based paint is flammable. Organic volatile solvents such as toluene, acetone, ethyl acetate curing agent and oth...
