Problems solved by technology

[0003] However, most of the current UV-curable coatings are oil-based paints, and a large number of organic solvents such as toluene, ethyl acetate, and butanone are used. The organic solvents volatilize and easily pollute the environment. Most organic solvents are poisonous and harmful to humans, animals and plants.

preparation example Construction

[0027] Wherein, the preparation method of the acrylic resin prepolymer comprises the following steps: vinyl trithiocarbonate, AIBN, acrylic monomer and 7-methacryloyloxy-4-methylcoumarin according to The molar ratio is 1:0.5:20~200:20~200, put it into the reaction bottle, add 1,4-dioxane, nitrogen protection, react at 80°C for 5h, and distill off the organic solvent under reduced pressure to obtain acrylic resin prepolymerization body.

[0028] Wherein, the acrylic monomer is selected from one of methyl methacrylate, methyl acrylate, butyl acrylate and hydroxyethyl methacrylate, glycidyl methacrylate, hydroxyethyl acrylate, hydroxypropyl acrylate , one of acrylonitrile.

[0029] Wherein, the emulsifier is preferably one or more of sodium styrene sulfonate, polyoxypropylene glyceryl ether, and nonylphenol polyoxyethylene ether.

[0030] Wherein, the dispersant is preferably Amp-95 or Sufynol 104BC.

[0031] Among them, the defoamer is preferably tributyl phosphate or polydim...

Abstract

This case involves a UV-curable acrylic resin water-based coating, which is made of the following components in parts by weight: 50-60 parts of acrylic resin prepolymer, 1-3 parts of defoamer, 1-3 parts of emulsifier, and 20-parts of filler 30 parts, 2-4 parts of dispersant, 100 parts of water. In the present invention, the ultraviolet light curing agent is directly grafted into the hyperbranched polymer structure, which can be cross-linked and cured in the molecule to form a three-dimensional network structure, and the curing efficiency is high; and the curing reaction only begins to cross-link and cure under ultraviolet light, Therefore, the performance of the final cured film is easy to control, and the construction difficulty of the coating is significantly reduced; the organic solvent is replaced by water, which has obvious advantages of environmental protection, non-toxicity, high efficiency, and cost reduction, and has significant economic and social benefits; Water-based paint has strong adhesion, fast surface drying speed, and high gloss of the paint film, which can be widely used in the coating of wood products.

Description

technical field [0001] The invention relates to the field of ultraviolet light curing coatings, in particular to a preparation method of an ultraviolet light curing acrylic resin water-based coating. Background technique [0002] Coatings are highly decorative, durable and protective, and multifunctional, and are widely used in various industries such as construction, home improvement, and automobiles. UV-curable coatings have the characteristics of saving energy, reducing air pollution, and fast curing speed, and are especially suitable for coating substrates that cannot be heated. Compared with traditional linear coating resins, hyperbranched polymers have the characteristics of three-dimensional structure, a large number of end groups, and no intramolecular and intermolecular chain entanglements. Mixing has good compatibility. [0003] However, most of the current UV-curable coatings are oil-based paints, and a large number of organic solvents such as toluene, ethyl ace...
