Problems solved by technology

If a master oil worker without construction experience carries out the construction, due to the uneven coating thickness of the transparent primer, it will lead to uneven or impossible coloring of the base color, and the final construction effect of the board will be greatly reduced
However, if you do not apply the transparent primer once, and use traditional primer color products to directly paint on the board, the phenomenon of color delamination or unevenness will appear after spraying the primer.

Abstract

The invention relates to a base brush-off composition for wood products, a method for preparing the base brush-off composition and a process for coating the same. The base brush-off composition for the wood products comprises, by weight, 10-60 parts of water-soluble hydroxy resin, 20-60 parts of solvents, 0.5-2 parts of dispersing agents, 5-20 parts of fillers, 1-10 parts of thickening agents, 2-90 parts of toner and 0.2-1 part of anti-skinning agents. A molar percent of hydroxy in the water-soluble hydroxy resin is 5%-20%. The base brush-off composition for the wood products, the method and the process have the advantages that base brush-off composition is high in adhesion, steps for coating priming paint prior to brush-off can be omitted, and the process can be simplified while grains of plates are highlighted.

Description

technical field [0001] The invention relates to paint products, in particular to a paint primer composition for woodware, a preparation method and a painting process thereof. Background technique [0002] Nowadays, with the improvement of living standards, people pay more and more attention to the individualized demand for color in home decoration, and the "colorization" consumption of paint products has formed a major trend. [0003] In the coating process of wood lacquer, the "undercoat surface repair process" known for its layering has always been favored by consumers. "Bottom surface repair process" is a coating process that highlights the texture of the board through the matching of the base color and the surface color. Among them, the bottom rubbing effect has the greatest impact on the overall layering. In other words, in order to obtain excellent texture effects, the primer product and its coating process are the key. [0004] When applying the traditional base pa...
