The invention provides a flame-retardant waterborne epoxy coating as well as a preparation method and application thereof, and belongs to the technical field of coatings. Comprising a component A and a component B, the component A is prepared from the following raw materials in parts by weight: 3-4 parts of a modified nano agent, 7-10 parts of water, 0.2-0.3 part of a water-based dispersing agent, 0.2-0.3 part of a water-based wetting agent, 0.2-0.3 part of a water-based defoaming agent and 3-5 parts of a water-based curing agent, and the component B is prepared from the following raw materials in parts by weight: 12-15 parts of epoxy resin and 1.2-1.5 parts of propylene glycol monomethyl ether. The flame-retardant waterborne epoxy coating prepared by the invention has better mechanical properties, high waterproofness, antifouling property and corrosion resistance, weather resistance, ultraviolet aging resistance and flame retardance, good room-temperature curing property, good storage stability and low VOC content, and has wide application prospects.
