NOVELTY - Aqueous anticorrosive paint comprises 40-70 pts. wt. aqueous composite emulsion, 10-30 pts. wt. pigment and filler, 5-10 pts. wt. multifunctional auxiliary agent, 0.1-1 pt. wt. thickener, 1-10 pts. wt. curing agent and 0-10 pts. wt. water. The multifunctional auxiliary agent is prepared by dispersing modified graphene compound (I) and 2,2-bis(formyloxymethyl)propane-1,3-diyl diformate based auxiliary dispersant compound (II) in water. USE - Used as aqueous anticorrosive paint. ADVANTAGE - The aqueous anticorrosive paint: utilizes multifunctional additive, which has anti-corrosion performance, dispersion performance and anti-settling performance, and can reducing risk of instability caused by too many types of additives; utilizes water as dispersion medium, which meets environmental protection requirements; utilizes auxiliary dispersant, which provides stable dispersion system for modified graphene and also a dispersant for paint system, and can firmly adsorbed by electrostatic interaction with pigment and filler ions to improves anti-settling performance of aqueous anticorrosive paint; utilizes modified graphene, which has excellent dispersibility in paint, improves uniformity of film formation, and excellent anti-corrosion performance; and has strong adhesion after spraying and is not easy to crack or peel off.
