Abstract
A titanium dioxide micro-nanocontainers, corrosion-resistant waterborne epoxy coatings and preparation method thereof, including preparation steps as follows: TiO2 micro-nano spheres are synthesized by applying hydrothermal method; a polyaniline layer doped with molybdate ions is deposited on the surface of TiO2 micro-nano spheres by adopting the method of in-situ chemical polymerization, TiO2/PANI-MoO42− micro-nano-spheres are obtained, then, polydopamine is encapsulated on the surface of TiO2/PANI-MoO42− micro-nano spheres to obtain titanium dioxide micro-nanocontainers; next, antirust filler, defoamer, dispersant and thickener are added into waterborne epoxy emulsion, then titanium dioxide micro-nanocontainers are added in the waterborne epoxy emulsion for dispersing and grinding, filtering and encapsulating to obtain component A; the waterborne epoxy curing agent and deionized water are mixed in proportion to obtain component B; component A is stirred, then it is mixed with the component B in proportion, corrosion-resistant waterborne epoxy coatings is obtained. According to the invention, the titanium dioxide micro-nanocontainers is synthesized and added into the coating as an…
