NOVELTY - Preparing a graphene-modified silicon nitride corrosion-resistant transparent coating involves taking 80-100 pts. wt. epoxy resin, 20-50 pts. wt. curing agent, 10-40 pts. wt. solvent, 1-10 pts. wt. modified silicon nitride and 1-10 pts. wt. modified graphene. USE - Method for preparing a graphene-modified silicon nitride corrosion-resistant transparent coating. ADVANTAGE - The method enables to prepare a graphene-modified silicon nitride corrosion-resistant transparent coating, which has good dispersibility in epoxy resin, high density and strong adhesion, simple operation, obvious effect, broad application prospect, exhibits wave transmission property, achieves good wave-transparing performance by standard for commercial wave-transparent materials with a dielectric constant of 3.42, and ensures corrosion protection of coating on carbon steel substrate.
