Abstract

The invention discloses a novel nano modified antimicrobial water-based woodware paint which comprises acrylic resin emulsion, polyurethane resin emulsion, nano silica sol, nano aluminum oxide, nano titanium dioxide, nano silver, film-forming assistant, defoaming agent, wetting and dispersing agent, leveling agent, thickening agent, wax emulsion and pH regulator. The nano materials dispersed in the water-based paint enhance the hardness of the coated film, so that the coated film has excellent yellowing resistance, aging resistance and mold resistance.

Description

technical field [0001] The invention relates to a wood coating, in particular to a nano-modified antibacterial water-based wood coating. Background technique [0002] 7,000 years ago, the primitive people in Hemudu, Yuyao, Zhejiang Province began to use wooden lacquered bowls. The Xia, Shang, and Western Zhou dynasties have gradually changed from purely using natural lacquer to using pigments to adjust the lacquer. People gradually understand and become familiar with the performance of lacquer, and use and transform the unique properties of lacquer, such as durability, no fading, no fear of moisture, bright and beautiful. , Serving to beautify one's own life, there is exquisite Chinese lacquerware, and people's life has been rich and colorful since then. However, with the development of the wood industry, China has become the largest exporter of wood products. Wood coatings generally use open coating, which causes a large amount of VOC emissions and poses a huge haz...
