Waterborne furniture primer and preparation method thereof and wood finishing construction technology

Abstract

The invention provides waterborne furniture primer and a preparation method thereof and a wood finishing construction technology. The waterborne furniture primer is prepared from, by weight, 90-95 parts of waterborne resin, 0.1-0.7 part of waterborne defoaming agent, 0.5-2 parts of waterborne wetting agent, 3-8 parts of waterborne cosolvent, 0.5-5 parts of waterborne thickener, 0.01-0.1 part of preservative and 0.01-1 part of pH auxiliary, wherein the waterborne resin is prepared from, by weight, 30%-65% of waterborne polyurethane resin and 40%-75% of waterborne acrylic resin. The obtained waterborne transparent primer has excellent stability, filling performance, permeability and overlapping performance, the primer is put in a baking oven at 50 DEG C for 10 days, the coating does not have any exception, and a spray plate effect is not changed; after 'three primer' procedures are carried out, wet film can cover all fine needle holes and guide tubes of the surfaces of boards; the transparency effect is good, and the primer is neither dimming nor blushing.

Description

technical field [0001] The invention relates to the field of coating preparation methods, and specifically discloses a water-based furniture primer, a preparation method thereof, and a wood finishing construction process. Background technique [0002] At present, when red oak solid wood is used as closed furniture material in the market, oil-based paint is often used for finishing. Oil-based paint emits a strong pungent smell during construction, most of which are formaldehyde and benzene volatile substances, which seriously endanger human health. Water-based paint Replacing oil-based paint can avoid the release of organic solvents. The existing water-based furniture transparent primer can achieve the paint finish effect on ordinary flat solid wood panels, but it is difficult to meet the filling and penetration requirements on red oak solid wood panels. There are many capillary pores. During the surface treatment process, the paint will penetrate into these capillary pores. ...

[0002] At present, when red oak solid wood is used as closed furniture material in the market, oil-based paint is often used for finishing. Oil-based paint emits a strong pungent smell during construction, most of which are formaldehyde and benzene volatile substances, which seriously endanger human health. Water-based paint Replacing oil-based paint can avoid the release of organic solvents. The existing water-based furniture transparent primer can achieve the paint finish effect on ordinary flat solid wood panels, but it is difficult to meet the filling and penetration requirements on red oak solid wood panels. There are many capillary pores. During the surface treatment process, the paint will penetrate into these capillary pores. The penetration of commercially available water-based paints is poor. Generally, three coats of primer are applied, but many pinholes will appear on the surface of the board after the paint film dries. and conduit corrugation, cannot completely seal the sheet

There is an urgent need to provide a water-based furniture primer to solve the problem of poor penetration of furniture primers in the prior art
