[0021] Correspondingly, the present invention also provides a preparation method of an organic-inorganic composite water-based paint, comprising the following steps: mixing iron powder, 1,3,5-trimesic acid, hydrofluoric acid, nitric acid and N,N-dimethyl Formamide is polymerized under hydrothermal conditions to obtain a metal-organic framework material; nano-titanium dioxide dispersion and talcum powder are added to the sodium silicate solution, and the metal-organic framework material and silica sol are added after the first stirring, Dispersant, leveling agent, defoamer, nonionic emulsion, styrene-acrylic emulsion, sodium acetate and water are stirred for the second time to obtain an organic-inorganic composite water-based paint.
[0022] As a preferred solution, in the step of obtaining the metal organic framework material, the temperature of the polymerization reaction is preferably 140-160° C., and the time of the polymerization reaction is preferably 8-20 hours. The conc...
