▎ 摘  要

NOVELTY - Aqueous epoxy graphene zinc-containing anticorrosive primer comprises component (A) and component (B), where the component (A) comprises 15-25wt.% aqueous epoxy zinc-rich resin, 5-10wt.% titanium dioxide, 0.2-0.5wt.% carbon black, 30-50wt.% zinc powder, 8-10wt.% nano-barium sulfate, 3-8wt.% strontium chromate, 0.3-0.8wt.% dispersant, 0.3-0.6wt.% defoamer, 0.1-0.2wt.% wetting agent, 0.5-1wt.% fumed silica, 0.5-1wt.% organic bentonite and 14-16.7wt.% cosolvent, where the component (B) comprises 85-90wt.% aqueous epoxy zinc-rich curing agent and 10-15wt.% functionalized graphene. USE - The primer is used in coating useful in railway bearing, railway bridge, railway locomotive, highway support, highway bridge, petroleum storage tank, petroleum pipeline, natural gas pipeline, petroleum equipment, engineering machinery, vehicle, transformer and other industries in different application. ADVANTAGE - The primer provides strong anti-corrosion effect on substrate.
