Abstract

The invention discloses high-performance water-based wood coating which is prepared from the following raw material components in parts by weight: 50-75 parts of silica sol-acrylic polyurethane composite emulsion, 1-5 parts of nanometer aluminum oxide, 1-5 parts of nano-zinc oxide, 0.1-0.25 part of polytetrafluoroethylene, 1-3 parts of bamboo charcoal powder, 0.5-3 parts of bentonite, 1-2.5 parts of alcohol ester 12, 1.5-3 parts of tripropylene glycol n-butyl ether, 0.1-0.8 part of 2,2,4-trimethyl-1,3-pentanediol isobutyrate, 0.1-0.3 part of 2-amino-2-methyl-1-propyl alcohol, 0.1-0.5 part of a silane coupling agent, 0.1-1 part of an antifoaming agent, 0.5-3 parts of a thickening agent and 5-20 parts of water. The high-performance water-based wood coating disclosed by the invention is high in strength, high in wear resistance and scratch resistance, excellent in antibacterial performance, high in water resistance and aging resistance, simplicity in construction and long in service life.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-performance water-based wood coating. 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 water resi...
