Abstract

The invention discloses a method for preparing a water-borne inorganic coating. The method comprises the following steps: 1)dispersing diatomite in an aqueous solution, performing ultrasonic agitation while dropping an anti-microbial compound water dispersion; standing the materials, performing multi-time suction filtration and cleaning, drying the materials to obtain a diatomite-anti-microbial compound; 2) under room temperature, mixing water and an antifoaming agent, adding a pigment and a filler, fully stirring the materials to obtain a solution A; 3) mixing silica sol and a polymer solution, fully stirring the materials, adding the diatomite-anti-microbial compound, and stirring the materials to obtain a solution B; 4) in the solution B obtained in the step 3), adding a coalescing agent and a thickening agent, fully stirring the materials to obtain a solution C; and 5) dropping the solution C in the solution A, fully stirring the materials, and filtering the material. The diatomite-anti-microbial compound material through reasonable matching and synergism between the functional additives provide excellent antibiosis and anti-formaldehyde characteristics of the inorganic coating, multifunctional requirements can be satisfied, and an application of the inorganic coating can be widened.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a preparation method of a multifunctional water-based 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 i...
