Abstract

The invention is suitable for the technical field of materials, and provides a water-borne wood paint and an application method thereof, the water-borne wood paint comprises a substance A and a substance B, wherein the substance A comprises the following components: 60-80w% of a re-emulsifiable emulsion, 3.5-15w% of an auxiliary agent, 2-25w% of a color paste and 5-15w% of deionized water, whereinthe re-emulsifiable emulsion is resin with a structural formula (I); the substance B is a hydrolyzed oligomer of glycidyl ether oxypropyl methyl diethoxy silane. The re-emulsifiable emulsion adoptedby the water-borne wood paint provided by the embodiment of the invention contains the hydrophilic group shown in the formula (I); in the spraying film-forming process, when the coating film encounters water again, the film-forming emulsion can be changed into emulsion particles again to be dispersed in water; and under the cross-linking matching effect of the substance B, the water resistance, solvent resistance, heat resistance and mechanical properties of a paint film are improved; therefore, the problem that a spray gun is blocked when the electrostatic rotary cup equipment is used for spraying is solved, and the electrostatic rotary cup equipment spraying method is suitable for spraying of the electrostatic rotary cup equipment based on a centrifugal atomization mode.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a water-based wood varnish and an application method thereof. Background technique [0002] After rapid development in recent years, the performance of water-based wood paint has been gradually improved. Although there is still some gap in the appearance of the paint film compared with solvent-based paint, it can be used on a large area in many occasions. In view of the fact that wood production is a traditional labor-intensive industry, many wood coatings are still very simple and primitive. However, with the disappearance of the demographic dividend and the needs of industrial upgrading, in order to make water-based wood paints clean and efficient, the coating process The upgrading and transformation of furniture is the top priority. In recent years, many furniture factories have also invested a lot of money to upgrade and transform spraying equipment, but basical...
