Problems solved by technology
It is not uncommon to use UV coatings for decoration on artificial leather. The organic UV coatings in the prior art often have the following key problems: 1. Odor problem. Most of the oily coatings often have irritation due to solvent residue or incomplete reaction. Second, environmental protection issues, there are VOC emissions during the preparation and use of oil-based coatings, and the solvent will be released when curing and heating; Third, cross-linking density, the cross-linking density of oil-based coatings is slightly lower

Embodiment Construction
[0031] The content of the present invention is further described below by way of examples.
[0032] 1. Preparation of waterborne fluorine-containing polyurethane-acrylic resin
[0033] Step 1: Mix methyl methacrylate, lauryl methacrylate, hexafluorobutyl methacrylate, and dodecafluoroheptyl methacrylate at a mass ratio of 1:1:0.2:0.4, and dissolve the above mixed monomers In butyl acetate whose mass is 5 times the total mass of the mixed monomers, the mixed solution is placed in a reactor and heated to 120°C, and then benzoyl peroxide of 6% of the total mass of the mixed monomers is added dropwise. Stir mechanically and react for 4 hours to obtain fluorine-containing acrylic resin.
[0034] Step 2: Mix the fluorine-containing acrylic resin prepared in step 1, dibutyltin dilaurate, and absolute ethanol in a reaction vessel at a mass ratio of 50:2:8, stir the reaction vessel to 80°C, and then Add isophorone diisocyanate with 5% mass of fluorine-containing acrylic resin, react ...

Abstract
The invention discloses a water-based UV paint used for artificial leather. The water-based UV paint comprises waterborne polyurethane resin, waterborne fluorinated polyurethane-acrylic acid resin, water, a photosensitive initiator, a delustering powder, a levelling agent, an antifoaming agent, and a dispersing agent. The water-based UV paint is preferably applied to roller painting of artificial leather, and can be taken as a painting decoration paint of automotive interior and exterior decoration; obtained paint films possess high crosslinking density, high adhesive force, small odour, and excellent acid and alkali resistance, is friendly to the environment, and is capable of saving energy.
Description
technical field [0001] The invention relates to a water-based UV paint, in particular to a water-based UV paint applied to artificial leather and a preparation method thereof. Background technique [0002] UV coatings are UV-curable coatings, which were first used in the furniture and flooring industries, and have the advantages of fast curing speed, low energy consumption, and low pollution. With the development of coating technology, UV coatings are gradually applied to plastics, paper, wood, metal, leather and other materials, becoming an important choice for decorative coatings in many industries. With the concepts of energy saving, emission reduction, environmental protection and safety gradually gaining popularity, water-based UV coatings and high-solid UV coatings are gradually showing a tendency to replace oil-based UV coatings of organic solvents. [0003] In the interior and exterior decoration of automobiles, many manufacturers no longer use leather decoration, b...
