Abstract

The invention discloses a preparation method of a water-based photochromic inorganic coating. The preparation method comprises the following steps: (1) dispersing kieselguhr into an aqueous solution, dropping antibacterial compound aqueous dispersion, performing stewing, suction filtration and cleaning, and drying to obtain a kieselguhr / antibacterial compound; (2) mixing and stirring water and a defoaming agent, then adding pigments, filler and kieselguhr / inorganic oxide, and stirring to obtain a solution A; (3) mixing and fully stirring silica sol and a polymer solution, adding the kieselguhr / antibacterial compound, and performing stirring to obtain a solution B; (4) adding a coalescing agent, a thickening agent and a photochromic compound into the obtained solution B, and fully stirring to obtain a solution C; (5) dropping the solution C into the solution A, and performing full stirring and filtration. The inorganic coating has excellent antibacterial and anti-formaldehyde characteristics as well as the photochromic property, and can meet the requirement for multiple functions; the application of the inorganic coating can be 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 photochromic 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 h...
