Abstract

The invention relates to the technical field of woodware coatings, in particular to an aqueous wood-wool filling agent coated onto a woodware, and a preparation method thereof. The aqueous wood-wool filling agent coated onto the woodware comprises distilled water, propylene glycol, a wetting dispersant reagent, a defoaming agent, a pH value regulating agent, powdery matter, aqueous polyurethane dispersoid (PUD) resin, antiseptic bacteriacide and droxyethylcellulose. The aqueous wood-wool filling agent coated onto the woodware is prepared through adding the materials at different time at different stirring speed. The aqueous wood-wool filling agent coated onto the woodware not only can be directly used without being diluted by a solvent, has short drying time and can be directly coated with primer without polish, but also can be manually operated and is environmentally friendly, and especially, the adhesion of the primer can be enhanced after the aqueous wood-wool filling agent coated onto the woodware is wiped and dried.

Description

Technical field [0001] The invention relates to the technical field of wood coatings, in particular to a water-based wood wool filler for wood coatings and a preparation method thereof. Background technique [0002] Wood wool filler plays the role of filling wood pipes and wood grain bristle eye pipes in the coating process of woodware. It can not only reduce the number of primer spraying, but also is convenient to use. It can be colored according to customer needs, while achieving filling With coloring purpose. The method of operation: wipe evenly with a cotton rag against the wood grain, or scrape it with a scraper; if a large area of ​​work needs to work quickly (not easy to wipe after drying), then use the cloth to wipe the wood grain clean. [0003] At present, the existing wood wool fillers are mainly ordinary oily wood wool fillers, which not only have poor adhesion to coatings, but also contain more organic solvents, which are not only environmentally friendly, but also ha...
