Preparation method of titanium dioxide/hollow microsphere composite filler

ActiveCN111378310AAvoid reunionAvoid overgrowthReflecting/signal paintsUltrasonic oscillationTitanium
The invention discloses a preparation method of a titanium dioxide / hollow microsphere composite filler. According to the method, a reversed-phase microemulsion system is adopted, an organic titanium source is slowly hydrolyzed on an oil / water interface through ultrasonic oscillation formed by small-frequency-band ultrasound, the surfaces of the hollow microspheres can be better coated with titanium dioxide crystal nucleuses due to the fact that the titanium dioxide crystal nucleuses are generated on a water phase layer; meanwhile, the reaction speed is controlled through two-step temperature rising, and the higher titanium dioxide film forming effect is achieved. According to the composite filler prepared by the method, the coating uniformity of titanium dioxide on the surfaces of the hollow microspheres is improved, so that the filler has obvious reflection performance and heat insulation and heat preservation effects.

The invention belongs to the technical field of anticorrosive materials in a marine environment, and particularly relates to an FG-coated MOF composite material, a coating containing the composite material, and preparation methods and application of the composite material and coating. The preparation method of the coating comprises the following steps: dispersing FG in absolute methanol, carryingout ultrasonic oscillation, adding a metal salt and an imidazole ligand into an FG methanol dispersion liquid, conducting stirring to obtain a turbid liquid, carrying out centrifugal separation to obtain a solid, alternately conducting washing with methanol and deionized water, and carrying out vacuum drying to obtain an FG-coated MOF composite material; and mixing epoxy resin, the FG-coated MOF composite material and a diluent, carrying out ball-milling stirring, adding a curing agent, and conducting uniform mixing to obtain a composite coating. A composite coating layer is obtained by coating the surface of a pretreated metal matrix with the composite coating, and conducting drying and curing. The epoxy resin is modified by the FG-coated MOF composite material, so that an imidazole ringin the composite material is chemically bonded with the epoxy resin, the problem of interfacial compatibility between the FG and the epoxy resin is solved, and the corrosion resistance and the mechanical property of an epoxy resin coating are improved.
