Along with economic progress, urbanization progress is accelerated, and buildings such as roads, bridges and high-rise buildings have higher and higher requirements on the performance of concrete. The concrete material is a durable material, but is a non-uniform porous material in nature, and can be gradually corroded under the erosion action of media such as carbon dioxide, water, chloride ions, sulfate and the like, so that the concrete is damaged in an accelerated manner, and the service life of the concrete material is greatly shortened. Floor coatings have been commonly used as ground protection materials.

The epoxy resin coating has excellent adhesive force to various substrates such as concrete and the like and low curing shrinkage; the wear-resistant rubber has the excellent chemical characteristics of high hardness, wear resistance, oil resistance, acid and alkali resistance, flexibility, salt spray corrosion resistance and the like; meanwhile, the paint has physical properties such as excellent stamping resistance, washing resistance and the like; the coating is widely applied to the coating of industrial floor coatings.
3. At present, the industrial floor coating in China mainly adopts solvent type epoxy floor coating and solvent-free type epoxy floor coating. The solvent-based epoxy floor coating contains a large amount of volatile organic solvents, and a solvent-free system adopts an epoxy active diluent, so that the solvent-based epoxy floor coating has certain toxicity and higher cost although the solvent-free system can participate in the reaction.
4. The film forming material of the water-based epoxy floor coating can be formed by compounding liquid epoxy resin or epoxy emulsion with different molecular weights and water-soluble amine or amine dispersoid, and the water-based epoxy floor coating can be prepared by adding color filler, auxiliary agent and the like in the colored paint component.
