The present invention relates to a functional coating composition and a method for preparing the same, comprising 5 to 15% by weight of a water-soluble inorganic binder in which Si (OH) 4 monomer is dispersed, 15 to 25% by weight of colloidal silica, functional nanomaterials and residual distilled water or ethanol Consist of; The functional nanomaterial provides a functional coating composition comprising any one or two or more selected from titanium dioxide photocatalyst 0.05 to 5% by weight, silver nano 0.1 to 30% by weight, and antimony tin compound 1 to 30% by weight. . According to the present invention, the adhesion of the coating layer is improved by maintaining a strong chemical bond with the substrate while ensuring high transparency without compromising the intrinsic color of glass, stone, wood, steel structures, paint surfaces, etc. used in buildings Since the material is not attached or fixed, it can be easily washed by rainwater, so the building cleaning cycle can be lengthened, maintenance costs can be reduced, and antibacterial / sterilization functions can be implemented as needed. |
