NOVELTY - An aqueous anticorrosive coating comprises 40-60 pts. wt. aqueous resin, 0.5-2 pts. wt. complex of titanium carbide (MXene) (I)/polyaniline, 1-3 pts. wt. film-forming aid, 15-25 pts. wt. curing agent, 0.5-1 pt. wt. coupling agent, 4-8 pts. wt. catalyst, 0.5-1 pt. wt. inorganic filler, 5-10 pts. wt. hydrophobic agent, and 50-70 pts. wt. deionized water. USE - Aqueous anticorrosive coating. ADVANTAGE - The aqueous anticorrosive coating has low volatile organic compound content and excellent barrier protection. The compound (I)/polyaniline complex is formed by in-situ polymerization of aniline on the surface of compound (I) and between the layers, and solves the problem of easy agglomeration of two-dimensional materials such as graphene in water, poor water solubility of polyaniline, and lamellar gaps and surface defects of compound (I). DETAILED DESCRIPTION - An aqueous anticorrosive coating comprises 40-60 pts. wt. aqueous resin, 0.5-2 pts. wt. complex of titanium carbide of formula: Ti3C2Tx (MXene) (I)/polyaniline, 1-3 pts. wt. film-forming aid, 15-25 pts. wt. curing agent, 0.5-1 pt. wt. coupling agent, 4-8 pts. wt. catalyst, 0.5-1 pt. wt. inorganic filler, 5-10 pts. wt. hydrophobic agent, and 50-70 pts. wt. deionized water. An INDEPENDENT CLAIM is included for preparation of the aqueous anticorrosive coating, which involves: (S1) dissolving complex of compound (I)/polyaniline in 10-20 pts. wt. water, and ultrasonically treating in an ice bath at 200-400 W for 0.3-1 hour; (S2) adding film-forming aid to 20-55 pts. wt. deionized water, and stirring for 0.3-1 hour; (S3) continuously adding aqueous resin, and stirring for 0.5-2 hours; (S4) continuously adding curing agent, catalyst and coupling agent, and stirring for 0.3-1 hour; (S5) continuously adding inorganic filler, hydrophobic agent and the sample obtained in step (1), and stirring for 1-3 hours; (S6) balling mill the stirred sample at 400-600 rpm for 4-6 hours; and (S7) passing the ball-milled sample through a 200-mesh and 600-mesh screen.
