Flat varnish for waterborne wood

Abstract

The invention discloses a flat varnish for waterborne wood, comprising the following components in parts by weight: 30-70 percent of waterborne acrylic emulsion, 0-30 percent of waterborne aliphatic polyurethane and mixture emulsion, 3-10 percent of film forming aid, 0.01-2 percent of antifoaming agent, 0.01-2 percent of dispersing agent, 0.1-5 percent of extinction powder, 0-2 percent of wettingagent, 0.01-2 percent of rheological additive, 0.01-2 percent of wax additive, 0.01-2 percent of hand-feeling addictive, 0.01-2 percent of thickening agent, 0.01-2 percent of ammonia water, 0.01-2 percent of coupling agent and 5-30 percent of water. The flat varnish for waterborne wood has the advantage of ensuring that a varnish film has better fullness, hardness, high chemical resistance, super-strong hand feeling and strong adhesive force on an oil primer. In addition, the flat varnish for waterborne wood can solve the compatibility between the aquosity and the oilness, ensure the varnish film cannot fall off after being dried and can meet the requirement for consumers on high environmental protection, low odor and less pollution.

Description

technical field [0001] The invention relates to a coating in the chemical industry, in particular to a protective coating applied to the surface of industrial wood furniture. 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 personnel 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 currently in the initial stage of technology, ...

Problems solved by technology

However, my country's water-based coatings are currently in the initial stage of technology, and the performance of the coating film often fails to meet the requirements of consumers, and there are defects such as easy collapse, insufficient filling, insufficient fullness, and weak hardness.
