The invention discloses an anticorrosive and environmentally-friendly water-based
coating. The
coating is mainly prepared from, by weight, 40-50 parts of waterborne
epoxy resin, 30-50 parts of a basematerial, 5-10 parts of a filler, 4-6 parts of modified
graphene oxide, 1-2 parts of a photocatalyst, 1-3 parts of an emulsifier, 2-3 parts of a
silicone acrylate leveling agent, 3-5 parts of
sodium diisooctyl sulfosuccinate, 2-5 parts of an NXZ
defoamer, 2-3 parts of
hydroxyethyl cellulose, 20-30 parts of deionized water and 0.5-1 part of 2-amino-2-methyl-1-
propanol. The invention also disclosesa preparation method of the
coating. The preparation method comprises the following steps: emulsification of the waterborne
epoxy resin, preparation of a filler mixture, preparation of a base materialmixture, and uniform
grinding and stirring.
Potassium silicate,
sodium silicate and silica
sol are compounded as a base material, the waterborne
epoxy resin is used as an
emulsion, and water as a dispersion medium, so environmental
pollution and resource waste caused by using of an
organic solvent are avoided, and the coating has no
pollution in the production or use process, and has excellent
environmental protection performance and mechanical performances.
