Abstract

The invention discloses an environmentally-friendly water-based wood sealer. The environmentally-friendly water-based wood sealer comprises a component A and a component B according to a weight ratioof 5-8. A preparation method of the environmentally-friendly water-based wood sealer comprises: (1) preparation of a component A solution: adding an aqueous acrylic resin emulsion into a container, and orderly adding a filler, a wetting agent, an anti-bleeding aid, an anti-settling agent and a defoamer into the container under the condition of medium-speed stirring, (2) preparation of a componentB solution: slowly adding tung oil into an alcohol solution under high-speed stirring, carrying out homogenization, and slowly adding the uniform solution into water containing a dispersant, (3) slowaddition of the B component solution into the component A solution under high-speed stirring and uniform mixing and (4) filtration with a filter net of 200 meshes. The preparation method is simple. The environmentally-friendly water-based wood sealer is environmentally friendly, safe and healthy, and has anti-corrosion and anti-bleeding ability.

Description

technical field [0001] The invention relates to the technical field of environmental protection paint, in particular to an environmental protection water-based wood sealing paint. Background technique [0002] Tung oil is the oil extracted from tung seeds, a special oil tree species in my country. It is an excellent drying vegetable oil with fast drying, light specific gravity, good gloss, strong adhesion, heat resistance, acid resistance, alkali resistance, anti-corrosion, Anti-rust, non-conductive and other characteristics, a wide range of uses. Due to its oil solubility, it is mostly used in organic solvent paints or inks. If tung oil is used in water-based paints, its application fields will be expanded and its effect will be greater. [0003] Water-based wood coatings use water as the dispersion medium and are healthy and environmentally friendly, so they have received much attention in recent years. However, water-soluble pigments in wood will bleed, so water-based w...
