▎ 摘  要

NOVELTY - Super-hydrophobic conductive anti-corrosion graphene coating comprises two components, where component one includes 40-60 pts. wt. synthetic resin, 0.5-5 pts. wt. auxiliary agent, 0.5-30 pts. wt. modified graphene, and 0.5-20 pts. wt. nanosheet solvent. The modified graphene nanosheets are graphene nanosheets treated with fluorine-containing silicon double-tailed chain compounds comprises 0-75 pts. wt. solvent, and 25-100 pts. wt. curing agent. The weight ratio of component one to component two is (100:10) to (100:80). USE - Super-hydrophobic conductive anti-corrosion graphene coating. ADVANTAGE - The super-hydrophobic conductive anti-corrosion graphene coating has good super-hydrophobicity, conductivity and corrosion resistance, and has good storage stability, is not easy to sink, and can realize a large area construction. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a super-hydrophobic conductive anticorrosive graphene paint, which comprises (A) preparing modified graphene nanosheets, adding 1000ml of deionized water to the three-necked flask, using organic phosphonic acid as a pH adjuster, adjusting the pH to 4-5, then adding 0.1-5 wt.% fluorine-containing silicon double-tailed chain compound of graphene nanosheets, dispersing and stirring for 5 to 30 minutes, then weighing into 10 to 100 g of graphene nanosheets, and stirring at 20 to 60 degrees C for 1 to 5 hours, washing, filtering, drying, and crushing the mixed solution of 1:1 by weight of water and ethanol to obtain modified graphene nanosheets; (B) adding the above modified graphene nanosheets to synthetic resin, additives and solvents, and stirring for 10 to 60 minutes to obtain super-hydrophobic conductive anti-corrosion graphene coating component one; and (C) dissolving second component of the super-hydrophobic conductive anti-corrosion graphene paint in the curing agent; and add the second component to the first component, curing at room temperature for 30 minutes to 7 days to form a super-hydrophobic conductive anti-corrosion graphene coating.
