Problems solved by technology

[0006] Although this construction method solves the problems encountered in batch construction of boards, this method includes roller coating and manual wiping process, the process is relatively cumbersome, and it is easy to affect the coating effect due to manual errors, and the coloring of wood pipes is insufficient.
At the same time, in the roller coating process, it is easy to cause uneven coloring due to insufficient coating amount.

Embodiment 1

[0050] The closed coating method for woodware of the present invention adopts water-based woodware coating as the basic coating, wherein the water-based woodware coating comprises the following components in parts by weight: 44 parts of water-based polyurethane resin, 8 parts of transparent powder, 0.3 part of dispersant, and 0.2 parts of variable agent, 0.8 parts of thickener, 0.3 parts of wetting agent, 4.9 parts of water-based color paste, 1 part of film-forming aid, 40 parts of water, and 0.3 parts of defoamer. The dispersant is a fatty acid dispersant, the rheological agent is organic bentonite, the thickener is polyacrylate mixed with cellulose ether in a mass ratio of 1:1, and the wetting agent is polyoxyethylene alkylphenyl ether , Polyoxyethylene fatty acid ester is mixed in a mass ratio of 1:1, the film-forming aid is compounded with diethylene glycol butyl ether and ethylene glycol in a ratio of 3:1, and the defoamer is emulsified silicone oil.

Embodiment 3

[0110] In the present embodiment, the water-based wood coating includes the following components by weight: 48 parts of acrylic resin, 9 parts of transparent powder, 0.4 part of dispersant, 0.3 part of rheological agent, 1.0 part of thickener, 0.4 part of wetting agent, 6 parts of water-based color paste, 1.2 parts of film-forming aid, 50 parts of water, and 0.3 part of defoamer. Among them, the film-forming aid is selected from propylene glycol butyl ether, the rheological agent is selected from castor oil derivatives and organic bentonite mixed with a mass ratio of 1:1, and the thickener is selected from bentonite, polyacrylate thickener and polyacrylate thickener. Mix at a mass ratio of 2:1:2, use W2001 (Beijing Moke Company) as the wetting agent, use acrylic acid copolymer potassium salt as the dispersant, and use emulsified silicone oil as the defoamer.

[0111] The production method is to mix the components of the above formula together and stir evenly. According to the ...

Abstract

The invention relates to a closed coating method for woodware, comprising a first spraying step: spraying water-based woodware paint on the surface of woodware to be treated to form a first coating, and drying the first coating for 2h-3h; second spraying Step: Spray the transparent primer mixed with filling powder on the surface of the first coating to form the first transparent primer layer, and dry for 2h-3h; repeat the second spraying step 2-4 times, in the first Form 2-4 layers of transparent primer layers on the surface of the transparent primer layer; the third spraying step: spray the color paste on the surface of the outermost transparent primer layer to form a color paste layer; spray the transparent primer on the The surface of the color paste layer is formed into a second transparent primer layer, and then dried for 2h-3h; the transparent topcoat is sprayed on the surface of the transparent primer on the surface of the color paste with at least one "ten" shape, and dried for 17h ‑23h. The coating process of the invention is simple and convenient, the coating is uniform, the wood grain is clear, the shadow effect is provided, and the coating can be applied in a large area.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a closed coating method for woodware. Background technique [0002] As a new type of environmentally friendly coating in the coatings market, water-based coatings are gradually accepted by the market because of their low-hazard and low-pollution characteristics. [0003] As an indispensable paint in the construction of water-based paint, water-based wood grain treasure is non-toxic, tasteless, easy to wipe, and can better show the natural style. Water-based wood grain treasure can penetrate into the pores of wood, and can adjust the light and shade of the color, increase the layering of the coating color and the clarity of the wood grain, make the material surface soft and form a contrast of light and dark and shadow effects, and improve the grade of furniture , has been favored since its listing. [0004] The construction method of the traditional water-based wood grain treas...
