Abstract

The invention discloses a high-water-resistance antibacterial waterborne woodware coating. The high-water-resistance antibacterial waterborne woodware coating comprises the following raw materials: a waterborne silica sol / acrylic polyurethane composite emulsion, nanometer silicon nitride, nanometer zinc oxide, bamboo charcoal powder, kaolin, doped nanometer titanium dioxide, benzyl alcohol, ethylene glycol butyl ether, 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate, dipropylene glycol, diglycol, 2-amino-2-methyl-1-propanol, a silane coupling agent, hydroxypropyl methyl cellulose, chitosan, a defoaming agent, a dispersant, a flatting agent and water. The high-water-resistance antibacterial waterborne woodware coating has the advantages of high strength, good abrasion resistance and scratch resistance, excellent water resistance and antibacterial property, good comprehensive property and long service life as the woodware coating.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based wood coating with high water resistance and antibacterial properties. Background technique [0002] Wood coatings refer to the coatings used on wood products including solid wood and wood-based panels, including furniture, doors and windows, wall panels, floors, daily necessities, wooden musical instruments, sporting goods, stationery, children's toys, etc. Generally speaking, wood coatings are mainly furniture coatings. Wood coatings give wood and wood-based materials desired aesthetic characteristics such as color and luster, while also making wood resistant to damage caused by moisture, bacterial growth, biodegradation, chemical damage, etc. [0003] Water-based wood coatings have become a research hotspot due to their non-toxic, environmentally friendly, less volatile matter, and high safety. Compared with solvent-based wood coatings, water-based wood coating...
