Preparation method of waterborne antibacterial inorganic coating

The invention discloses a preparation method of a waterborne antibacterial inorganic coating. The preparation method includes following steps: (1), dispersing diatomite in a water solution, ultrasonically stirring while dropwise adding an antibacterial compound water dispersion solution, standing, performing suction filtration cleaning for several times, and drying to obtain a diatomite / antibacterial compound; (2), at room temperature, mixing and stirring water and a defoamer, adding pigment and a filler, and fully stirring to obtain a solution A; (3), mixing silica sol with a polymer solution, fully stirring, adding the diatomite / antibacterial compound, and stirring to obtain a solution B; (4), adding a film forming auxiliary and a thickener into the solution B obtained in the step (3), and fully stirring to obtain a solution C; (5), dropwise adding the solution C into the solution A, fully stirring, and filtering. By reasonably matching a diatomite / antibacterial composite material and diatomite / inorganic oxide and through synergism among functional additives, the inorganic coating has excellent antibacterial, anti-formaldehyde and deodorizing characteristics and meets multifunctional needs, and application range of the inorganic coating is further expanded.
