Problems solved by technology

[0006] However, in order to achieve a good wiping and construction effect, the current water glas on the market often cannot take into account the stability requirements at the same time, especially the yellowing resistance. The usual water glas has very poor yellowing resistance. If such The product is used for antique white paint. After a long time, the surface color of the illuminated part is prone to deepen or turn green, which will bring different colors to the overall furniture and greatly affect the painting effect.

preparation example Construction

[0055] The present invention also provides a kind of preparation method of Water Grace, comprising the following steps:

[0056] 1) After mixing the water-based resin and water, mixture A is obtained;

[0057] After mixing the dispersant, defoamer, wetting agent, cosolvent and pH regulator, mixture B is obtained;

[0058] 2) Add the mixture B obtained in the above steps to the mixture A obtained in the above steps, and then add the filler to continue mixing to obtain the mixture C;

[0059] 3) Add a thickener, an antifungal agent and a color paste to the mixture C obtained in the above steps, and mix again to obtain the Water Gris.

[0060] In the preparation method of the present invention, the specific preferred scheme of the raw material, and the preferred numerical value of the number of parts added are consistent with the specific preferred scheme of the components in the aforementioned Water Gris, and the preferred numerical value of the number of added parts, and are n...

[0074] A kind of Water Grace comprises the following components according to mass percentage:

[0075] Alkali-swellable water-based resin emulsion (B-70): 15%, 5040: 1%, BYK028: 0.3%, propylene glycol 10%, AMP-95: 1.5%, tegowet270: 0.2%, BEK-200L: 0.2%, TT-615 : 1.5%, talcum powder: 10%, transparent iron oxide color paste: 20%, deionized water: 60.3%.

[0076] The preparation steps of Water Grace are as follows:

[0077] (1) According to the above mass fraction, first mix B-70 with deionized water to obtain mixture A, and then pre-mix 5040, byk028, tegowet270, propylene glycol, and AMP-95 to obtain mixture B. At 400-500rpm, mixture B Add slowly to mixture A;

[0078] (2) After the addition of mixture B, add talcum powder and disperse at 2000rpm for 20 minutes to obtain mixture C;

[0079] (3) Finally, add TT-615, BEK-200L and transparent iron oxide color paste to mixture C, and disperse at 1000rpm for 20 minutes to obtain Water Gris.

Abstract

The invention provides a water-based glaze which comprises the following components in parts by weight: 5-25 parts of water-based resin, 0-1 part of dispersing agent, 0.2-0.5 part of defoaming agent, 0.2-0.4 part of wetting agent, 10-20 parts of cosolvent, 1-2 parts of pH regulator, 1-3 parts of thickener, 0.1-0.3 part of mildew preventive, 0-20 parts of filler, 5-20 parts of color paste and the balance of water. The yellowing-resistant water-based glaze has excellent wiping property and excellent yellowing resistance, and can keep no discoloration for a long time under illumination conditions. Thus, the furniture color of the wood products applied by the glaze can keep constant. The water-based glaze has the advantages of high coloration effect, high transparency, high layering sensation and moderate drying time, and is very convenient for on-site construction.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water glazing and its preparation method and application, in particular to a yellowing-resistant water glazing and its preparation method and application. Background technique [0002] Paint is coated on the surface of the object to be protected or decorated, and can form a continuous solid film firmly attached to the object to be coated, also known as paint film or coating, usually based on resin, or oil, or emulsion, adding Or do not add pigments, fillers, add corresponding additives, and use organic solvents or water to prepare viscous liquids. There are many types of coatings. According to the form of the product, they are mainly divided into: solvent-based coatings, water-based coatings, powder-based coatings, high-solid coatings, metallic coatings, pearlescent coatings, and solvent-free coatings. [0003] With the increasing awareness of environmental protection in the ...
