Surface Treatment and Application in Acrylic Polyurethane Coating of ZnO Nano Powder

Abstract:

In this paper, the ZnO nano powders were prepared by sol-gel method and modified with diphenyl-methane-diisocyanate (MDI). The modified ZnO nano powders can disperse in acrylic polyurethane coating homogenously. The dispersion stabilization of modified ZnO nano powders in acrylic polyurethane coating was significantly improved in comparison with the native ZnO nano powders, which was due to the introduction of grafted polymers by surface treatment. The ultraviolet absorption ability of ZnO nano powders were tested by UV spectrophotometer, when the modified ZnO nano powders are added into the acrylic polyurethane coating. The addition amount of ZnO powders is more; the ultraviolet absorption ability is stronger.
