Antibacterial nano paint

The invention relates to the technical field of coatings, in particular to antibacterial nano paint. Comprising the following specific raw materials: 18-25 parts of deionized water; 0.5 to 1.2 parts of a wetting dispersant; 0.2 to 0.4 part of a composite nano material; 15 to 20 parts of water-borne epoxy resin; 1 to 3 parts of nanometer silicon-based oxide; 15 to 20 parts of titanium dioxide; 20 to 25 parts of a waterborne epoxy curing agent; 0.8 to 1.2 parts of a cosolvent; 0.3 to 0.5 part of a polysiloxane type defoaming agent; 20 to 25 parts of acrylate emulsion; 2-5 parts of polytetrafluoroethylene wax powder; 0.5 to 1 part of a thickening agent; 0.4 to 0.6 part of a flatting agent; 2-4 parts of a coalescing agent; and 1-3 parts of a wetting agent. The antibacterial nano-paint provided by the invention has a good antibacterial effect after being used for a long time, can solve the problems of poor dispersibility of a nano-material in water-based paint and low stability of a water-based paint product, and
