Abstract
The invention relates to the field of coatings, and particularly discloses a self-cleaning antibacterial coating and a preparation method thereof. The self-cleaning antibacterial coating is prepared from the following substances in parts by weight: 80 to 100 parts of matrix emulsion, 3 to 10 parts of water, 0.1 to 5 parts of functional additive, 4 to 8 parts of self-cleaning antibacterial particles and 15 to 50 parts of composite filler, the self-cleaning antibacterial particle is a microsphere with a core-shell structure, the microsphere with the core-shell structure comprises an inner core matrix and a coating layer coating the surface of the inner core matrix, and the coating layer is a porous titanium dioxide aerogel film. The preparation method comprises the following steps: S1, preparing materials; s2, mixing, grinding and dispersing; s3, performing secondary mixing; according to the invention, the formula and composition of the coating are optimized, and the structure of the self-cleaning antibacterial particles is further optimized, so that the surface pollutant loading resistance is improved, and the antibacterial durability is improved.
