Problems solved by technology

Epoxy floor coatings can be divided into two types: solvent-based and solvent-free. Although solvent-based epoxy floor coatings have the advantages of low cost, dense and hard paint film, high hardness, and low shrinkage, solvent-based epoxy floor coatings Flat coatings contain a lot of organic solvents, which will emit a certain amount of volatile organic compounds (VOC) during production, construction and curing, which is harmful to the environment and personnel.
[0003] With the enhancement of environmental regulations and people's awareness of environmental protection, water-based epoxy industrial floor coatings have been researched and developed. Compared with ordinary solvent-based epoxy floor coatings, water-based epoxy floor coatings use water as the dispersion medium and do not contain Volatile organic solvent, will not cause environmental pollution, no fire hazard, meets the current environmental protection requirements, but it is not suitable for low temperature construction, it will corrode the coating equipment greatly, the water resistance and compactness of the paint film are poor, and the leveling property is average , the cost of industrial large-scale construction is too high
[0004] Epoxy self-leveling floor coatings combine the advantages of the above two types of floor coatings, but their existing preparation method is a grinding method, which has large waste and high energy consumption; at the same time, the leveling of the paint film is not good, there are trowel marks, and At present, the gloss of many domestic manufacturers' products is low, not more than 85%, and the epoxy resin content is more than 40%, the pigment content is high, and the cost is high
