Problems solved by technology

With the development of water-based coatings, more and more attention has been paid to the research of water-based epoxy resins. However, due to the large number of benzene rings in the molecular structure of epoxy resins, the flexibility and impact resistance of the coating film are poor, which limits the use of water-based epoxy resins.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an anti-corrosion polyurethane-epoxy resin composite emulsion coating. Background technique [0002] The film-forming substance of the anti-corrosion coating has chemical stability in the corrosive medium, and its standard is related to the composition and chemical structure of the film-forming substance, mainly to see whether it is easy to react with the corrosive medium or decompose in the medium under dry film conditions into small molecules. Epoxy resin has good physical and chemical properties after curing, excellent bonding strength to the surface of metal and non-metal materials, good dielectric properties, small deformation shrinkage rate, good dimensional stability of products, high hardness and high flexibility Well, it is stable to alkali and most solvents, so it is widely used as a film-forming substance for metal anti-corrosion coatings. With the development of wa...
