Problems solved by technology

Grace is a coloring agent for wiping, which can fill the color into the tube holes of wood, and can adjust the light and shade of the color by wiping, increasing the layering of the coating color and the clarity of the wood grain, but the traditional style Lise has the problem of weak penetration and easy fading, which can easily lead to peeling and cracking of the top coat. Therefore, it is necessary to study a water-based Lisi with good penetration and good adhesion to the water-based primer.

preparation example Construction

[0039] The invention provides a kind of preparation method of the modified water glas, comprising the following steps:

[0040] 1) Under low-speed stirring, add water and cellulose in sequence according to the weight of each component of Waterglass, adjust the stirring speed to 400-600r / min, slowly add PH additives, stir for 10-15min, then stir uniform.

[0041] 2) Add water-based defoamer, water-based dispersant, water-based co-solvent and water-based polyurethane resin in sequence according to parts by weight, stir for 30-40 minutes, and then stir evenly.

[0042] 3) Slowly add talcum powder, adjust the stirring speed to about 1000-1200r / min, stir for 20-30min, and stir evenly to obtain the modified water gelis.

[0043] In steps 1), 2), and 3), the stirring speed and stirring time are very important in the preparation process of the Water Gris, because the stirring speed will affect the compactness of the Water Gris coating film. Different stirring speeds will cause densi...

Abstract

The invention provides a modified aqueous glaze, a preparation method, and a wood finishing construction technology. The modified aqueous glaze comprises the following components in parts by weight: 0.1 to 0.4 part of aqueous polyurethane resin, 0.2 to 0.5 parts of cellulose, 15 to 40 parts of aqueous cosolvent, 0.2 to 0.5 part of aqueous antifoaming agent, 0.01 to 0.05 part of aqueous dispersant, 30 to 50 parts of talcum powder, 0.01 to 1 part of pH aid, and 10 to 50 parts of water. The drying speed of modified aqueous glaze is reduced in the brush-off technology, the modified aqueous glaze has a good filling effect without affecting the original color of sheets, and moreover, the obtained aqueous glaze will not precipitate and does not need to be stirred or diluted by water before using. The glaze can be applied to the aqueous woodware finishing technology, the compatibility between the glaze and various aqueous primers is good, the interlayer binding force between the glaze and various primers is strong, during the drying process, the glaze appears good transparency and permeability, and the glaze does not give off irritant smell.

Description

technical field [0001] The invention relates to the field of wood lacquer, and specifically discloses a modified water-based lacquer, a preparation method thereof, and a wood finishing process. Background technique [0002] Water-based wood lacquer is a coating product that is applied on the surface of wooden furniture or wood products. In addition to its protective effect on wood products, it also needs to have a certain decorative effect. In the coating process of water-based wood coatings, the American coating process occupies a very important position. American-style coating is an open coating. By deepening the contrast of wood grains and enhancing the sense of layering and three-dimensionality of the wood surface, the natural patterns of the wood are fully highlighted, bringing a natural and beautiful texture to the furniture. American-style painting is also called antique painting. By cooperating with some special plate treatment and color rubbing techniques such as o...
