Zinc-Rich Epoxy Anti-Corrosion Coating and Preparation Method Thereof

摘要

The present invention relates to a kind of bi-component graphene anticorrosive paint, the coating includes the component A of energy film-forming and the second component containing curing agent; Wherein, component A includes following component by mass percentage: graphene 0.1-5wt%; Zinc powder 0-35wt%; Filler 30-70wt%; The epoxy resin 10-20wt% that solid content is 54%; Solvent 10-20wt%; Wherein, the sum of mass percentage of graphene, zinc powder and filler is 60-80wt%, and the sum of described component A each component mass percentage is 100w%. Graphene is added in anticorrosive paint by the present invention, greatly reduces the thickness of coating paint film; The content of zinc powder is greatly reduced while improving anti-corrosion effect by the selection to each component, the anti-corrosion mode for overcoming zinc-rich paint to sacrifice zinc powder as cost greatly reduces the zinc oxide fog generated in welding, environmental-friendly.
