Abstract

The invention provides an oil stain used for coloring a wood lacquer. The oil stain mainly comprises the following raw materials in percentage by weight: 10%-20% of short oil resin, 10%-20% of thixotropic resin, 30%-50% of aromatic solvent, 1%-4% of wetting dispersant and 10%-30% of pigment. The invention also provides a method for preparing the oil stain used for coloring the wood lacquer and a coating method thereof. The oil stain provided by the invention has the basic performance of the traditional wiping stain, and the color types, shade, brightness and other properties thereof can be selected according to pigments and dyes; and the oil stain is suitable for coating the wood lacquer or is used for the bottom coloring in the ultra violet roller painting process, the whole coloring process can be completely finished in a wiping mode, and a hierarchical effect can be displayed by selecting and collocating the pigments and the dyes.

Description

technical field [0001] The invention relates to an oily colorant, a preparation method and a coating method thereof, in particular to an oily colorant, a preparation method and a coating method thereof for the oily wood lacquer coloring and wiping process and the ultraviolet curing roller coating coloring process . Background technique [0002] Colorants are commonly used raw materials in the production of wooden furniture and wooden handicrafts. Common colorants are all solvent-based, and their production technology generally uses benzene, ketones or ether esters as solvents, and a long-oil alkyd resin is used to grind together with pigments to form a pigment slurry. The colorant produced by this method has disadvantages such as long storage time, easy return to coarse, precipitation and adhesion. Contents of the invention [0003] An object of the present invention is to provide an oily colorant for wood lacquer coloring, to overcome the above-mentioned defects in the ...
