Problems solved by technology

[0003] Traditional epoxy resin must use organic solvents in the process of use, so the system contains organic volatiles, which will not only cause serious pollution to the environment, but also pose a great threat to human health. At the same time, the quality of the coating is not high, The preparation process is cumbersome and the labor intensity of the operators is high

Description

technical field [0001] The invention relates to the technical field of chemical coatings, in particular to a water-based epoxy resin coating and a preparation method thereof. Background technique [0002] Epoxy resins are widely used in coatings, adhesives, composite materials and many other fields because of their excellent physical and chemical properties. Most of the traditional epoxy resin coatings are insoluble in water and have a high viscosity. During construction, a large amount of organic solvents need to be added for dilution, which will cause harm to the ecological environment and the health of construction workers. In the past ten years, the application fields of water-based epoxy resins have become wider and wider, and oil-based epoxy resins have been replaced in some fields. As people pay more and more attention to environmental protection, water-based epoxy coatings are likely to eventually completely replace solvents. Type epoxy coating. Since the performan...
