Abstract

The invention provides a colorant composition, which comprises an agent A and an agent B, wherein the agent A comprises the following components in parts by weight: 5-50 parts of aqueous resin, 5-50 parts of alcohol solvent, 5-50 parts of alcohol ether solvent, 0.1-1 part of pH regulator, 0.1-5 parts of thickening agent, 0.1-2 parts of flatting agent, and 10-50 parts of water; the agent B comprises 100 parts of water-soluble color concentrate in weight. The colorant composition provided by the invention is an aqueous colorant; the agent A is a main colorant; the agent A contains aqueous resin; the drying speed of the colorant composition is slowed in the presence of aqueous resin, therefore, the wiping time is proper; the colorant composition provided by the invention is applied to large-area construction; the agent A is free from organic solvents, such as benzene series; the construction taste is little; the colorant composition provided by the invention is lower in health hazard to operators and also lower in environmental pollution; the agent B is the aqueous coloring solution and high in solid content; the agent B and the agent A are good in compatibility, and therefore, the prepared colorant composition is free from decolouration and color separation.

Description

technical field [0001] The invention relates to the technical field of coatings and processing thereof, in particular to a colorant composition and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, the home decoration style is developing in the direction of colorization, high-end and personalization. Wooden furniture and wooden handicrafts occupy a large part of home decoration, and more surface protection and decoration are needed to highlight the decoration style. [0003] Colorants are commonly used raw materials in the production of wooden furniture and wooden handicrafts. Colorants can impart color to various furniture and home decoration panels, so as to achieve a decorative effect that combines beauty and high-end. [0004] In the prior art, common colorants in wood furniture paints are solvent-based. Solvent-based colorants contain a large amount of volatile organic solvents, such as benzene s...
