Waterborne UV (Ultraviolet) furniture coating and preparation method thereof

Abstract

The invention discloses a preparation method of waterborne UV (Ultraviolet) furniture coating. The preparation method comprises the following steps: firstly, conveying a waterborne acrylate pre-polymer and an active diluting agent into a high-pressure reaction kettle; introducing carbon dioxide and enabling carbon dioxide to be at a supercritical fluid state through adjusting pressure and temperature in the high-pressure reaction kettle; keeping the pressure and temperature in the high-pressure reaction kettle unchanged; adding other auxiliary agents in sequence according to the ratio; sufficiently stirring and reacting to obtain a finished product. The waterborne UV furniture coating prepared by the method has the advantages of easiness for controlling the viscosity, good storage stability, convenience for construction, green and environment-friendly preparation technology and high production efficiency; the waterborne UV furniture coating can be completely dried after being irradiated through an ultraviolet lamp for several seconds; a dried paint film has high rigidity, good toughness, good water resistance, good wearing resistance, good pollution resistance and good plumpness; all indexes meet national standards, and a decoration effect and a protection effect are strong; the waterborne UV furniture coating has a good adhesive force on various base materials and is applicable to coating of various high-end indoor wood furniture and indoor wood floors.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based UV furniture coating and a preparation method thereof. Background technique [0002] With the gradual enhancement of modern people's awareness of environmental protection, countries have successively formulated environmental protection regulations on VOC emissions, and the emission standards have become increasingly strict, aiming to encourage the promotion of new green and environmentally friendly products. Therefore, in the field of coatings, it is necessary to vigorously develop and apply safe, low-VOC environment-friendly coatings. [0003] In recent years, UV UV-curable coatings have developed rapidly. Its advantages are fast curing, low energy consumption, excellent performance of the cured paint film, and high production efficiency. However, with the in-depth application of UV coatings in various fields, its shortcomings are gradually exposed. come out. Co...

Problems solved by technology

[0004] However, the existing water-based UV coatings also have poor storage stability, poor water resistance, wear resistance and solvent resistance of the paint film, and are not easy to coat the substrate.
