Characterization of ZnO Nano-Coatings on Fibreboard

Abstract:

Article Preview

Different concentration of self-made ZnO nanoparticles were mixed with waterborne woodenware coatings to determine characteristics of the coatings applied to wooden samples. The particle sizes for ZnO nanoparticles were 20 nm respectively. Concentrations of 0.2, 0.4, 0.6, 0.8, and 1.0 wt-% of ZnO nanoparticles were individually mixed into the aqueous polyurethane AE-418 and into aqueous acrylic resin WP-1715. These coatings were applied with a wire-wound rod. The differences of the coatings with and without nanoparticles are compared. Results reveal that the light reflectance value of the coating was increased by 12.4 %, is the highest. The hardness of the coating increased gradually with the increase in the ZnO content. When ZnO nanoparticles were mixed into the aqueous polyurethane, AE-418, with an increase of four grades, is the highest. The adhesion of the coating increased gradually with the increase in the ZnO content.
