Water-based high-solid-content quick-drying edge sealing paint and preparation method thereof
Technical Field

Background
The edge sealing paint is mainly used for filling up and sealing edges of the side surfaces and the tangential surfaces of the density boards, the shaving boards or the melamine boards, so that the artwork achieves better primer coating effect. The traditional furniture edge sealing paint mainly comprises oily PU and NC edge sealing paint, is unsafe to store and transport because of containing a large amount of organic solvents, has high construction VOC, and has great harm to the environment and paint constructors, and is slowly replaced by water-based edge sealing paint.
Chinese patent CN101812266B and chinese patent CN102241941B mention the preparation of edge sealing paint using aqueous polyurethane as the main film forming material, its construction solids content is up to about 70%, however its filling properties, dry speed and hardness are to be improved, and the cost is slightly higher with polyurethane resin as primer. Chinese patent CN102746748B adopts water-free redispersible emulsion powder as main resin, improves the solid content (about 77% at maximum) of the edge sealing paint, thereby accelerating the drying speed of a paint film, and improves the hardness of the paint film by matching wollastonite, but the patent still needs mixed water-based polyurethane as a film forming substance, and the wetting property of the water-based polyurethane is much better than that of acrylic emulsion on a base material and powder.
In the environment of raw material price surge, a plurality of paint enterprises should be charged with price, and the orderly operation of the enterprises is ensured. Therefore, the water-based edge sealing paint with low cost, high solid content, good hardness and quick drying is more needed in the current market.
