[0027] First add water-based acrylic resin and water-based polyurethane-modified acrylic resin dispersion into the dispersion tank, then add defoamer, matting agent, film-forming aid, wetting agent and dispersant under medium-speed stirring, and rinse the tank with water Wall and rotating shaft, then disperse at high speed for about 30 minutes until the fineness is less than 35um, and finally add thickener under medium speed stirring, stir evenly, and pack 100 kg of the product of the present invention.
[0028] First, coat the wood with 2-3 times of water-based one- or two-component water-based wood paint, or 2-3 times of PU paint or oil-based UV paint. The specific number of times can be determined according to the desired effect. Re-coat...

Abstract
The invention belongs to the technical field of water-based paints and particularly relates to a water-based shower-coated super matte toning finishing coat. The water-based shower-coated super matte toning finishing coat comprises the following components in percentage by weight: 35-45% of water-based acrylic resin, 16-20% of water-based polyurethane modified acrylic resin, 0.1-0.2% of a defoamer, 3-5% of a flatting agent, 5-7% of a film coalescing agent, 0.5-1% of a wetting agent, 0.5-1% of a dispersant, 0.5-1% of a thickener and the balance of water. The water-based shower-coated super matte toning finishing coat provided by the invention can solve the problems that the conventional water-based shower-coated paint is likely to foam, shrink, generate rash and fade and the like during shower coating, and has a uniform and smooth paint film with a good surface effect and super matte glossiness. The water-based shower-coated super matte toning finishing coat is high in hardness, good in fullness, good in weather resistance, excellent in flexibility, good in handfeel, high in glossiness and excellent in water resistance and chemical resistance and has good adhesive force on a solvent polyurethane wood paint (PU), a nitrocellulose paint (NC), an unsaturated polyester paint (UE) and an oily UV light-cured paint.
Description
technical field [0001] The invention belongs to the technical field of water-based paints, and in particular relates to a water-based spray-coating extra-dumb toning finish paint. Background technique [0002] At present, the wood coatings used for curtain coating are basically polyurethane wood coatings (PU), nitrocellulose coatings (NC), and unsaturated polyester (PE, oil-based UV light-curing paints). However, for reasons of environmental protection, the flow-coated wood lacquer has a tendency to gradually develop towards the water-based direction. The traditional water-based wood paint is not easy to wet the substrate due to its high surface tension, so it is necessary to increase the amount of wetting agent (surfactant). Difficulty, there are many surface bubbles, the effect is not good. If a strong defoamer is used or the amount of defoamer is increased, the risk of shrinkage crater or mirror frame effect is easy to occur. When water-based wood paint is used as a su...
