Water-based UV (ultraviolet) woodware adhesion colorant mother solution and preparation method thereof

Abstract

The invention discloses a water-based UV (ultraviolet) woodware adhesion colorant mother solution and a preparation method thereof. The colorant mother solution is prepared from 70-80 parts of water-based UV polyurethane acrylate emulsion, 1-1.5 parts of photoinitiator, 2-4 parts of cosolvent, 0.2-0.5 part of defoaming agent, 1-2 parts of wetting and dispersing agent, 1-2 parts of thickener, 0.2-0.5 part of amine neutralizer and 10-15 parts of deionized pure water. The colorant mother solution has higher adhesive force between the coating and the substrate, and favorable compatibility and dispersity with water-based dyes and water-based pigments, highlights the layered sensation of the colored wood grains, can perform mechanical application operation to enhance the coloring efficiency of the produced board, is green, environment-friendly and pollution-free for the environment, and ensures the safety of the production enterprise and user.

Description

technical field [0001] The invention relates to the technical field of wood coloring chemical materials, in particular to a water-based UV wood adhesion colorant mother liquor and a preparation method thereof. Background technique [0002] The paints commonly used in the furniture industry are traditional solvent-based complexed metal dyes. Solvent-based paints have the disadvantages of strong odor, long drying time, unclear texture of wood coloring effect, and unsatisfactory adhesion effect of colored coatings; in addition, traditional Solvent-based colorants are constructed by spraying, which has low efficiency, high cost, pollutes the environment, and affects the health of construction workers; at the same time, traditional solvent-based paints contain flammable, explosive, and organic volatile solvents (such as toluene, acetone, ethyl acetate, etc.) curing agent, etc.), these solvents are very likely to bring fire hazards to manufacturing companies; finally, the products...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides a water-based UV wood adhesion colorant mother liquor and its preparation method to solve the problem that the current wood coloring materials have a large odor, and the wood coloring effect is not clear after a long drying time. , The adhesion effect of the colored coating is not ideal, to ensure the safety of the use of materials for enterprises and people
