Abstract

The invention discloses a one-component water-based semi-gloss varnish and a preparation method thereof. The one-component water-based semi-gloss varnish comprises the raw material formulas in percentage by mass: 30-60% of water-based acrylic emulsion, 5-30% of water-based aliphatic series polyurethane emulsion, 3-10% of film forming assistant, 0.01-2% of antifoaming agent, 0.01-2% of dispersing agent, 0.1-5% of extinction powder, 0.01-2% of wax assistant, 0.01-2% of hand feeling assistant, 0.01-2% of thickening agent, 0.01-2% of cross-linking agent and 5-40% of water. The one-component water-based semi-gloss varnish of the invention has the advantages of super strong hand feeling, high fullness, high hardness, good chemical resistance, very low bodily injury on production and construction workers, and very low environmental pollution.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to water-based coatings, in particular to a one-component water-based matte varnish with super strong hand feeling and a preparation method thereof. Background technique [0002] At present, most of the wood coatings used in my country are solvent-based, and these wood coatings contain a large amount of volatile organic compounds (VOC), which seriously endanger the health of production and construction personnel. [0003] With the enhancement of people's awareness of environmental protection, traditional solvent-based coatings are facing severe challenges, while water-based coatings have the advantages of non-toxic, non-flammable, and non-polluting environment, and have attracted more and more attention. [0004] Water-based coatings combine the high performance of solvent-based coatings with the low VOC content of water-based coatings, which have good environmental effects and rel...
