Problems solved by technology

At present, water-based UV high-gloss wood paints have the disadvantage of losing gloss after light curing when photoinitiators are added for a long time without shading treatment or sprayed thickly. Now the high-gloss wood paint is mainly controlled by controlling the amount of paint spray. Drawbacks of paint loss

Embodiment approach

[0029] As a preferred embodiment of the present invention, the polyurethane dispersion system is composed of the following materials and parts by weight: 1-5 parts of bissulfonylimide salt, 20-30 parts of acrylate, 20-30 parts of diisocyanate, dihydroxy 10-15 parts of methacrylic acid, 1-10 parts of polyether polyol, 0.1-1 part of dibutyl tin dilaurate, 0.5-3 parts of triethylamine, 40-60 parts of deionized water.

[0030] As a preferred embodiment of the present invention, the structural formula of the bissulfonylimide is:

[0031]

[0032] R1 is an alkane with 1-12 carbons, fluorine atom, benzene ring, pyridine or furan; R2 is an alkane with 1-12 carbons, fluorine atom, benzene ring, pyridine or furan.

[0033] As a preferred embodiment of the present invention, in the structural formula of the bissulfonylimide, M is selected from lithium in alkali metals, sodium, potassium or triethylamine cations in ammonium ions, tetramethylammonium, nitrogen methyl imidazole one or m...

Embodiment 1

[0062] According to the formula of the present invention, 30 parts of polyurethane dispersion system (1 part of bis-sulfonimide salt), 10 parts of nonafluorobutyl acrylate, 6 parts of epoxybutene, 1 part of diol, propylene isophorone 0.05 parts, 0.2 parts of polyether modified polydimethylsiloxane solution, 3 parts of allyl ether sulfonate, 2 parts of propylene glycol methyl ether acetate, 3 parts of photoinitiator, 15 parts of deionized water and mix well A high-gloss wood lacquer with high hardness is obtained. Spray high-hardness high-gloss wood paint on the surface of the wood, level the sprayed wood for 1 hour, dehydrate at a temperature of 50-60°C, UV cure for 20 minutes, keep the temperature at 50-60°C for 30 minutes at a humidity of 30, and then drop to room temperature.

[0063] Measure the hardness H of the paint, the adhesion is 4, and the gloss is semi-matte.

Embodiment 2

[0065] According to the formula of the present invention, 30 parts of polyurethane dispersion system (1.5 parts of bissulfonylimide salt), 10 parts of nonafluorobutyl acrylate, 6 parts of epoxybutene, 1 part of diol, propylene isophorone 0.05 parts, 0.2 parts of polyether modified polydimethylsiloxane solution, 3 parts of allyl ether sulfonate, 2 parts of propylene glycol methyl ether acetate, 3 parts of photoinitiator, 15 parts of deionized water and mix well A high-gloss wood lacquer with high hardness is obtained. Spray high-hardness high-gloss wood paint on the surface of the wood, level the sprayed wood for 1 hour, dehydrate at a temperature of 50-60°C, UV cure for 20 minutes, keep the temperature at 50-60°C for 30 minutes at a humidity of 30, and then drop to room temperature.

[0066] Measure the hardness H of the paint, the adhesion is 3, and the gloss is semi-matte.

Abstract

The invention discloses a high-hardness and high-gloss wood lacquer. The high-hardness and high-gloss wood lacquer is prepared from the following materials in parts by weight: 30 to 50 parts of a polyurethane dispersion system, 10 to 30 parts of fluorine-containing acrylate, 5 to 10 parts of epoxy olefin, 1 to 5 parts of dihydric alcohol, 0.05 to 0.1 part of propylene isophorone, 0.2 to 1 part ofa polyether modified polydimethylsiloxane solution, 3 to 10 parts of a reactive emulsifier, 2 to 5 parts of propylene glycol methyl ether acetate, 3 to 6 parts of a photoinitiator and 10 to 20 parts of deionized water.

Description

technical field [0001] The invention relates to wood paint, in particular to a high-hardness high-gloss wood paint. Background technique [0002] The history of human production and use of paint can be traced back to the Stone Age. A large amount of archaeological data has been found to prove that in the primitive society 7,000 years ago, human beings have used the fat, tree sap and natural pigments of wild animals to prepare primitive finishing materials, and painted with feathers and branches to achieve decoration. the goal of. [0003] In the last century, major achievements in the scientific theory of polymers and the successful development of various polymer compounds have been put into production, creating a new era for the development of paints. In the 1920s, alkyd resins specially used as film-forming substances for paints were successfully developed. Since then, various newly developed synthetic resins have been quickly applied in paints, making paints enter the e...
