▎ 摘  要

NOVELTY - A curing agent comprises 30-58 wt.% polyamide resin, 1-2 wt.% graphene oxide, 0.1-0.2 wt.% dicyclohexyl dicarbonimide and 40-68 wt.% mixed thinner. USE - Curing agent for anticorrosive epoxy primer (claimed). ADVANTAGE - The curing agent has excellent anti-settling property, anti-reunification function and excellent corrosion resistance property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the method for producing curing agent for anticorrosive epoxy primer, which involves uniformly dispersing oxidized graphene in the mixed amount of the formulated diluent, obtaining oxidized graphene diluent, adding dicyclohexyl dicarbonimide and polyamide resin to the graphene oxide diluent, warming at 100-110 degrees C, opening the condensate back, stirring for 2-4 hours, cooling to 45-55 degrees C, adding remaining polyamide resin, and mixing evenly after filtration to remove impurities.
