Problems solved by technology

However, these processes are relatively complicated, especially the surface color correction process. Because the surface coatings used are different, the coating time and coating methods are different, and it is not easy to operate. If the personnel without construction experience carry out the construction, the surface coating color will Different shades and uneven coating thickness will affect the construction effect. Therefore, the surface repair process has become a major bottleneck for the majority of paint construction personnel. Only a very small number of top-notch construction technicians can engage in this work.
The bottleneck in surface color repair technology limits the scope of use of colored transparent top coats, which can occupy a large market share, and cannot meet market demand. It is also difficult for surface color repair technicians to repair the color evenly and color the color during large-scale construction. Overall effect is poor
[0005] In the wood paint surface coloring process, surface color correction is the most commonly used one, but one of its disadvantages is that it is difficult to color evenly in a large area, resulting in poor overall construction effect; It is difficult for skilled technicians to work; the third defect is that it cannot evenly color the board surface with complex shapes

preparation example Construction

[0055] The present invention also provides a kind of preparation method of wood paint colorant composition, comprising:

[0056] Uniformly mix the matrix resin with the wetting and dispersing agent and solvent system (esters, ketones, aromatic hydrocarbons, alcohol ethers, alcohol solvents) to obtain a pre-dispersed mixture;

[0057] Stir and disperse the above pre-dispersed mixture and the metal complex dye evenly to obtain a colorant resin composition.

[0058] According to the invention, it is also optional to add defoamers and leveling agents to the mixture. It is also optional to stir and disperse the mixture for 5-10 minutes; then disperse the mixture in the mixed solvent for the second time, and the time for the second dispersion is preferably 5-8 minutes. A uniformly dispersed resin composition is obtained without delamination and bubbles.

[0059] The present invention also provides a coating construction method of the wood lacquer colorant composition, comprising: ...

Abstract

The invention provides a coloring agent composition for wood lacquer, which is prepared from the following components: 5-40 parts of matrix resin, 0.5-10 parts of metal complex dye, 8-40 parts of esters solvent, 15-50 parts of aromatic hydrocarbon solvent, 0.5-20 parts of ketone solvent, wherein the matrix resin is plant oleoresin or long oil-length alkyd resin. The coloring agent composition for wood lacquer provided by the invention has favorable coloring performance, has short coloring time, is convenient for coating and construction, can be used for personnel without long-term construction experience, and can obtain a good coating effect. The invention also provides a preparation method of the coloring agent composition for wood lacquer..

Description

technical field [0001] The invention relates to the field of coatings and processing thereof, in particular to a method for preparing and coating a wood paint colorant composition. Background technique [0002] Paints and coatings are materials commonly used in building decoration materials, especially in furniture decoration and wall decoration, which are more and more widely used. With the decoration style towards color, high-end, personalized development. The higher-grade solid wood furniture needs more surface protection and decoration. [0003] At present, the film-forming substances of commonly used wood lacquers are mostly polyester resins. The paint films formed by polyester resins are film-resistant, scratch-resistant, and corrosion-resistant, and have a good protective effect. Moreover, polyester resins are easy to color and can form Make the wood surface form a variety of colors and patterns, making the wood more beautiful. [0004] The coloring process of wood...
