Compared with traditional solvent-based and solvent-free floor coatings, the existing waterborne epoxy floor has the following advantages: (1) It contains no organic solvent or low volatile organic compound content, no environmental pollution, and meets the requirements of current environmental maintenance. (2) Good gas permeability, which solves the problems of coating film bubbling, peeling off and the like which are easy to occur in conventional solvent-based and solvent-free floor coatings. (3) It has no content of organic solvents or volatile organic compounds, no environmental pollution, and meets the requirements of current environmental maintenance; (4) Good hardness, water resistance and chemical corrosion resistance;
