Abstract

The invention discloses a water-based one-component paint and a preparation method thereof. The water-based one-component paint is composed of the following raw materials: nano polyacrylic acid emulsion, water-based polyurethane emulsion, defoamer, dispersant, thickener, pigment, filler , alumina slurry, film-forming aids, pH regulator, anti-mold and bactericide and water; the water-based one-component coating obtained by the present invention has good fullness, good airtightness, excellent adhesion and fast drying, and anti-collapse Strong resistance and high hardness; the water-based one-component paint obtained by the present invention can be used directly by adding water, no use time limit, no water is added for use, and can be used as white putty without collapse; the water-based one-component white background obtained by the present invention The paint is a water-based green environmental protection product; the preparation method of the water-based one-component paint provided by the invention is simple in operation and convenient in preparation, and is suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the technical field of wood lacquer, in particular to a water-based one-component paint and a preparation method thereof. Background technique [0002] With the further improvement of environmental protection regulations, in order to reduce the load on the earth, new low-VOC or zero-VOC emission coatings have become the focus of research and development. The research, development, promotion and application of water-based wood coatings have attracted more and more attention. In recent years, the research and development of water-based wood paint has achieved unprecedented development in our country. [0003] Water-based wood paint has been successfully applied in home decoration and ordinary furniture, and is expanding its market share. However, in the high-end furniture market controlled by oil-based polyurethane paint, the market share of water-based paint is relatively small. High-grade furniture paint requires high fullnes...
