▎ 摘  要

NOVELTY - Hydrochloric acid-hydrogen sulfide corrosion resistant coating comprises 6-aminopyridine-2-carboxylic acid, graphene nano sheet, organic resin, diethylene glycol butyl ether, organosiloxane resin, dispersant, preservative filler, flatting agent, antifoaming agent and water. The preparation of hydrochloric acid-hydrogen sulfide corrosion resistant coating comprises subjecting 6-aminopyridine-2-carboxylic acid and graphene nano sheet for esterification reaction to obtain graphene 6-aminopyridine-2-carboxylic acid, functionalizing 6-6-aminopyridine-2-carboxylic acid to organic resin to obtain the organic resin material functionalized with 6-aminopyridine-2-carboxylic acid, mixing and stirring diethylene glycol butyl ether, organosiloxane resin, dispersant, preservative filler, flatting agent, antifoaming agent and water. USE - Used as hydrochloric acid-hydrogen sulfide corrosion resistant coating. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing hydrochloric acid-hydrogen sulfide corrosion resistant coating, comprising (i) preparing organic resin material functionalized with graphene 6-aminopyridine-2-carboxylic acid; and (ii) mixing organic resin material functionalized with graphene 6-aminopyridine-2-carboxylic acid with diethylene glycol butyl ether, organosiloxane resin, dispersant, anti-corrosive filler, leveling agent, antifoaming agent and water evenly.
