[0038] The present invention also discloses a preparation method of water-based yellow sealing paint, comprising the following steps

[0039] (1) Prepare the raw materials, including the following percentage components:

[0040] 20-22.5% water-based yellow sealing self-crosslinking acrylic acid, 20-22.5% water-based solvent-free sealing yellow self-crosslinking acrylic acid, 2-2.5% film-forming co-solvent, 7-8% water, 0.3-0.8% defoamer , 0.2-1.5% leveling agent, 0.2-1.5% wetting agent, 40-42.5% powder, 0.3-1.5% thickener.

[0041] (2) Under normal temperature conditions, water-based yellow sealing self-crosslinking type acrylic acid and water-based solvent-free sealing yellow self-crosslinking type acrylic acid are put into the high-speed disperser according to the percentage. Mix liquid, defoamer, wetting agent, leveling agent, powder, thickener, stir for 20-30 minutes.

[0042] (3) The detection fineness is less than or equal to 40 microns.

[0043] (4) Detect pH at 7.5-9...

Abstract

The invention discloses a water-based yellow sealing coating, which is characterized by comprising water-based yellow sealing self-crosslinking acrylic acid, water-based yellow sealing solvent-free self-crosslinking acrylic acid, a film-forming cosolvent, water, a defoaming agent, a flatting agent, a wetting agent, powder and a thickening agent, wherein the water-based yellow-sealing solvent-free self-crosslinking acrylic coating is prepared from the following components in percentage by mass: 20 to 22.5 percent of water-based yellow-sealing self-crosslinking acrylic acid, 20 to 22.5 percent of water-based yellow-sealing solvent-free self-crosslinking acrylic acid, 2.0 to 2.5 percent of film-forming cosolvent, 5 to 6 percent of water, 0.3 to 0.8 percent of defoaming agent, 0.2 to 1.5 percent of wetting agent, 0.2 to 1.5 percent of flatting agent, 40 to 42.5 percent of powder and 0.3 to 1.5 percent of thickening agent. According to the water-based paint, water is used as a solvent, so that the use of an organic solvent is effectively reduced, and the emission of VOCs is low; moreover, the water-based self-crosslinking acrylic acid can be used for yellow sealing without adding any curing agent or crosslinking agent, and the wetting agent and the flatting agent are added in the formula system, and meanwhile, the whole paint liquid system can be driven to wet and flatly spread on the medium density fiberboard, and the whole paint film has excellent compactness on the medium density fiberboard, thereby achieving the yellow sealing effect.

Description

technical field [0001] The invention relates to the technology in the field of coatings, in particular to a water-based yellow sealing coating and a preparation method thereof. Background technique [0002] With the rapid development of my country's social economy, consumers have higher and higher requirements for the quality of life. In terms of home decoration and furniture purchase, the demand for high-end solid wood furniture is much higher than that of panel furniture or wood-based panel furniture. [0003] Water-based paint is a polymer material that uses water instead of organic solvents in traditional oil-based paints as a dispersion medium. It has the advantages of non-toxic, non-polluting, low odor, non-flammable and non-explosive. However, the water-based paints on the market have a single function, mainly through water-based polymers to improve the feel and smoothness of the paint film, and do not have the excellent yellow sealing function on MDF. Therefore, the...
