Abstract

A water multifunctional woodenware lacquer and its production are disclosed. The lacquer consists of water acrylic modified polyurethane resin emulsion 60.0-90.0%, water 5.0-20.0%, wetting agent 0.1-1.0%, anti-foaming agent 0.1-1.0%, thickener 0-1.0%, smoothening agent 0-2.0%, leveling agent 0.1-1.0%, flatting agent 0-1.0%, inorganic nano-antibacterial agent 0.01-0.1%, cellulose ester 0.1-1.0%, composite nano-anionic additive 1-5% and accessories. The process is carried out by adding various components except emulsion and leveling agent into water, agitating to obtain the mixed slurry, grinding by sand mill or triple-roller machine, filtering to obtain half-finished mixed liquid, adding water acrylic modified polyurethane resin emulsion into half-finished mixed liquid, agitating to obtain mixed material and adding into leveling agent to obtain the final product. It's cheap, simple, has no environmental pollution and excellent anti-mycotic effect. It can be used in both indoor and outdoor.

Description

technical field [0001] The invention relates to a multifunctional water-based wood paint and a preparation method thereof. Background technique [0002] At present, most of the traditional wood lacquers are solvent-based wood lacquers. Due to the large amount of volatile solvents used, volatile organic compounds (VOC) will be produced during its production and use, especially some organic compounds containing benzene, which are easy to damage human nerves, mucous membranes, Skin, liver and windpipe damage and even cancer. Solvent-based wood lacquers are mostly solvent-based polyurethane and nitro-based lacquers, which pollute the environment and affect people's health. In developed countries such as Europe and the United States, the consumption is declining year by year. With the continuous growth of environmental awareness around the world, The environmental regulations of various countries are becoming increasingly strict, so many large foreign companies have invested hea...
