The invention relates to the technical field of functional antibacterial coatings, in particular to a modified nano silicon dioxide reinforced fluorocarbon resin antibacterial coating as well as a preparation method and application thereof. The coating has efficient antibacterial performance on standard strains and drug-resistant strains (such as aspergillus niger). According to the material, copper pyrithione and vinyl fluoride-vinyl ether resin form a fusion system, modified nano silicon dioxide inorganic particles are further introduced, the composite antibacterial coating is formed, the water resistance of a coating is remarkably improved, and meanwhile the excellent antibacterial performance is kept. The coating is particularly suitable for long-term protection of wood surfaces in (ancient) buildings and gardens, and an efficient and low-concentration novel solution is provided for solving the problems that a traditional coating is poor in antibacterial property, insufficient in drug-resistant bacterium resistance and the like. The composite antibacterial coating also provides more efficient and stable protection for wood exposed in the environment for a long time, has a wide application prospect, and can be used in multiple fields of building, garden, cultural heritage protection and the like.
