Description

technical field [0001] The invention relates to the field of wood lacquer design, in particular to a water-based wood varnish with high weather resistance. Background technique [0002] Wood paint refers to a type of resin paint used on wood products, including polyester and polyurethane paints. In the past, most of the wood lacquers were oil-based wood lacquers, but oil-based wood lacquers required the use of organic solvents, such as "thinna water" or "banana water", which caused serious environmental pollution and easily caused great damage to users, and were easy to burn. In order to solve the above-mentioned problems of oil-based wood lacquers, there are currently many water-based wood lacquers on the market that use water as a solvent. Because water-based wood lacquers are non-toxic, environmentally friendly, odorless, have very little volatile matter, and are non-flammable and non-explosive. High safety With the enhancement of people's awareness of environmental pro...
