Abstract

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.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a preparation method of a water-based antibacterial inorganic coating. Background technique [0002] Inorganic coatings mainly refer to coatings prepared by using silicate and phosphate compounds as binders, adding various pigments, fillers, additives, and curing agents. Among them, silicate polymer compounds can be divided into alkali metal Silicates and silica sols. This kind of coating with inorganic binder as the film-forming substance has low film-forming temperature, excellent weather resistance, very stable under the action of ultraviolet light, good heat resistance, non-combustible in case of fire, and good resistance to heat. Pollution, not easy to absorb dust, can maintain a bright decorative effect, no volatile organic compounds are produced during production and use, will not pollute the environment, rich raw material resources, low cost and other advantages, so it ...
