Problems solved by technology

[0003] At present, the commonly used floor coating materials on the market are epoxy materials, which have the advantages of high strength, good gloss, and corrosion resistance compared with traditional concrete or granite floors; however, epoxy floors have poor flexibility, poor It is very easy to crack, has low anti-skid performance, and cannot be constructed in winter, and the progress of the project is greatly restricted by temperature and climate
And in the prior art, solvents such as esters or aromatic hydrocarbons are often used as diluents for floor coating materials. Although they can reduce the viscosity of the system, the problem that often occurs is that they cannot improve the performance of coating materials, and there is safety and environmental pollution. Hidden dangers; In order to solve the above problems, the existing technology will further use plasticizers such as dioctyl phthalate and dibutyl phthalate to improve the plasticity of the obtained material, but the problem is that such plasticizers The safety of plasticizers is still controversial, and there may be safety risks such as carcinogenicity, and with the increase of the service time of coating materials, such plasticizers are prone to diffusion and migration, which not only makes the coating materials brittle and deformed, but also causes the coating materials to A layer of oil stains is formed on the surface, causing safety accidents
