Problems solved by technology
Compared with the performance of oil-based wood coatings, water-based wood coatings generally have problems such as poor paint film performance, and the actual drying time of water-based coatings on the market is generally above 4 hours. Therefore, it is necessary to develop a fast-drying environmental protection water-based Wood varnish has very important economic benefits and social value for promoting the comprehensive water-based of wood coatings and promoting the transformation and upgrading of wood coatings

Abstract
The invention relates to environment-friendly water-based wood varnish, in particular to water-based wood gloss varnish and discloses quick-drying type acrylic acid and polyurethane environment-friendly water-based wood gloss varnish and a preparation method thereof. The quick-drying type acrylic acid and polyurethane environment-friendly water-based wood gloss varnish is prepared from components in percentage by weight as follows: 30%-50% of a water-based acrylic resin emulsion, 25%-45% of a water-based polyurethane resin emulsion, 3%-8% of a coalescing agent, 0.1%-0.5% of a base material wetting agent, 0.1%-0.3% of an antifoaming agent, 0.5%-1.0% of a thickening agent, 0.1%-0.5% of a leveling agent, 0.1%-0.5% of a slipping and wear-resisting agent and 5%-15% of water. The preparation method of the quick-drying type acrylic acid and polyurethane environment-friendly water-based wood gloss varnish comprises steps as follows: water, the water-based acrylic resin emulsion and the water-based polyurethane resin emulsion are added to a dispersion vat for medium-speed dispersion, the coalescing agent, the thickening agent, the wetting agent, the antifoaming agent and other components are added, after medium-speed dispersion, the fineness and viscosity of a finished product are detected through sampling, and filtration, canning and packaging are performed. The VOCs (volatile organic compounds) of the product can be effectively reduced, the varnish film performance can be remarkably improved, and the varnish has excellent characteristics of quick drying and high strength.
Description
technical field [0001] The invention relates to an environmental-friendly water-based wood varnish, in particular to a quick-drying acrylic polyurethane environmental-friendly water-based wood varnish and a preparation method thereof. Background technique [0002] Oil-based wood coatings use various organic solvents such as benzene, ketones, esters, ethers, etc. as dispersion media. And during the drying process, it will continue to volatilize into the air or be absorbed by the human body, which will seriously damage the environment and harm human health. Water-based wood coatings use water as the dispersion medium, which completely eliminates the harm of organic solvents to the human body, and has incomparable advantages over traditional oil-based coatings, such as green, environmental protection, health, energy saving, etc. [0003] my country's water-based wood coatings started late, the overall technical level is relatively backward, and the application is also limited....
