Embodiment 1

[0026] A method for preparing a marine anti-corrosion architectural coating with the function of inhibiting microbial activity, which is prepared from two components: inorganic component A and organic component B;

[0027] Specific steps are as follows:

[0028] (1) Prepare component B:

[0029] Add 20.7mL of aminopropyltriethoxysilane, 6.9mL of n-octyltriethoxysilane, and 5.94ml of deionized water into 32.23mL of ethyl acetate solution, stir at room temperature, and add 3.3mL of acetic acid dropwise during stirring , after stirring for 2-3 hours, stand and age for 20-26 hours, and it is in the state of microsol;

[0030] (2) Prepare component A:

[0031] After the aging of component B, start to prepare component A, weigh 4.8g of nano-silica treated with trimethylchlorosilane, soak it in 10ml deionized water, disperse it by ultrasonic wave for 15 minutes, and add 20ml concentration dropwise Silver nitrate solution with c=0.2mol / l, mixed and stirred at 30°C for 1 hour, then ...

Abstract

The invention discloses a preparation method of an ocean anti-corrosion building coating with the function of inhibiting microbial activities. The prepared coating can be used for inhibiting the corrosion effect of microorganisms on buildings, and is applicable to ocean environment and humid environment. Organic catalyst or solvent is not required to be added in the preparation process, the coating is an environmentally-friendly anti-corrosion building coating. Nanosilicon dioxide particle loaded Ag+ and inorganic filler modified montmorillonite loaded nano-zinc oxide in the coating are adhered to the surface of the material through curing and film formation, the microbial activities are inhibited, so that the base materials are doubly protected, and a preferable anti-corrosion effect is reached. The coating is harmless for the environment, long in service cycle, cheap in raw materials and simple in method, and has excellent market generalization.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a method for preparing a marine anti-corrosion architectural coating with the function of inhibiting microbial activity. Background technique [0002] At present, the interpenetrating network structure of organosiloxane has been applied in coatings, but most of them are compounded or copolymerized with some organic coatings such as epoxy resins and acrylate emulsions. The production process is complicated and needs to be added Organic catalysts and organic solvents are harmful to the environment. At the same time, anti-corrosion coatings in the marine environment seldom take into account the role of microorganisms. The microbial activity of concrete corrosion is also a very important factor. How to prepare a coating that is harmless to the marine environment and can inhibit microbial activities is this patented technology research focus. Contents of the invention [0003...
