▎ 摘 要
NOVELTY - A bi-component graphene-based corrosive-resistant coating material comprises curable film-forming component (A) and component (B) containing curing agent, in a weight ratio of 10:1. The component (A) contains 0.1-5 wt.% graphene, 0-35 wt.% zinc powder, 30-70 wt.% filler, 10-20 wt.% epoxy resin with solid content of 54%, and 10-20 wt.% solvent. The total content of graphene, zinc powder and filler is 60-80 wt.%. The solvent is mixed solvent of xylene and isobutanol in a weight ratio of 1:1-4:1. The dispersion solvent of epoxy resin is xylene. USE - Bi-component graphene-based corrosive-resistant coating material is used for forming coating film. ADVANTAGE - The economical and environmentally-friendly bi-component graphene-based corrosive-resistant coating material forms thin coating film having excellent corrosion resistance with reduced content of zinc powder, and reduces zinc oxide mist generated during welding.
