Water-based single-component matte varnish

Abstract

The invention discloses water-based single-component matte varnish, which comprises the following components in parts by weight: 20-50 percent of water-based pure polyacrylic emulsion, 20-50 percent of self-extincted polyacrylic emulsion, 5-30 percent of water-based aliphatic polyurethane and mixture emulsion, 3-10 percent of film-forming auxiliary agent, 0.01-2 percent of defoaming agent, 0.01-2 percent of dispersing agent, 0-2percent of wetting agent, 0.01-2 percent of rheological auxiliary agent, 0.01-2 percent of wax auxiliary agent, 0.01-2 percent of hand-feeling auxiliary agent, 0.01-2 percent of thickening agent, 0.01-2 percent of pH regulator and 5-30 percent of water. The water-based single-component matte varnish has the advantages of high environment-friendly property, high fullness, high rigidity, high hand feeling, high construction property and high chemical resistance, and meanwhile, the self-extincted emulsion is adopted in the formula for extinction, so that the water resistance and the alcohol resistance of a varnish film are greatly enhanced, and the harsh requirements of partial customer services on the water resistance and the alcohol resistance are met.

Description

technical field [0001] The invention relates to a coating in the chemical industry, in particular to a water-based one-component matte varnish. 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. With the enhancement of people's awareness of environmental protection, traditional solvent-based coatings are facing severe challenges. Water-based coatings have the advantages of non-toxic, non-flammable, and non-polluting environment. 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 relatively convenient construction. However, my country's water-based coatings are now in the initial stage of technology, especially the one-component water-based matte ...

AI Technical Summary

Problems solved by technology

However, my country's water-based coatings are now in the initial stage of technology, especially the one-component water-based matte varnish, which has technical defects such as insufficient fullness, low hardness, poor hand feeling, poor chemical resistance, especially poor water resistance and alcohol resistance.

If you use traditional pure acrylic emulsion or polyurethane emulsion, add an appropriate amount of matting agent and various functional additives, it is difficult to meet the requirements of customers for water resistance and alcohol resistance, and it is even more difficult to meet the requirements of export furniture for paint resistance.
