Preparation and properties of waterborne epoxy coatings modified by TiO2 transparent emulsion

Li Huo, Pengfei Zhang, Li Wan

TiO2 transparent emulsion were prepared by using normal temperature hydrolysis and added into the waterborne epoxy coatings, the properties of coating films including hardness, adhesion, flexibility, impact resistance were characterized. The visible-light photocatalytic activities of different contents of TiO2 transparent emulsion in the samples were evaluated using the degradation of rhodamine B. The result shows that waterborne epoxy coatings doping TiO2 have the photocatalytic performance and have the optimal weight ratio (W(TiO2)/W(waterborne epoxy coatings) = 2 %), the properties of the films are still unchangsd, which it may be actual applied.
