Abstract

The invention belongs to the field of coating, and particularly relates to water-based woodware lacquer coating capable of scavenging formaldehyde. The water-based woodware lacquer coating capable of scavenging formaldehyde is prepared from the following raw materials in parts by weight: 5-30 parts of distilled water A, 40-60 parts of polyacrylic emulsion A, 0.1-0.5 part of base material wetting agent, 0.5-2 parts of dispersing wetting agent, 0.1-1 part of deforming agent, 5-10 parts of polyacrylic emulsion B, 1-3 parts of distilled water B, 0.1-1 part of pH conditioning agent, 0.1-1 part of thickening agent, 10-30 parts of titanium dioxide slurry, 5-15 parts of heavy calcium powder, 1-10 parts of talcum powder, 1-5 parts of distilled water C, 1-5 parts of dipropylene glycol mono butyl ether, 1-5 parts of dipropylene glycol monomethyl ether, 0.5-3 parts of formaldehyde scavenging additive, 0.5-3 parts of propylene glycol and 0.1-1 part of bactericide. The water-based woodware lacquer coating capable of scavenging formaldehyde has high strength, good formaldehyde scavenging performance, good wear resistance and scratching resistance, an excellent antibacterial property, good water resistance and aging resistance, stain resistance and long service life.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a water-based wood lacquer capable of removing formaldehyde. 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 coatings still have deficiencies in wate...
