▎ 摘  要

NOVELTY - An intermediate paint coating comprises mica iron oxide red and graphene. USE - Intermediate paint coating is useful in epoxy resin anticorrosive coating (claimed). ADVANTAGE - The intermediate paint coating has excellent hydrophobicity, barrier property, shielding effect and corrosion resistance and prolonged service life, reduces amount of volatile organic compound, and can be prepared in economical manner. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) epoxy resin anticorrosive coating, which comprises 20-30 pts. wt. intermediate paint coating, 10-20 pts. wt. epoxy resin, 0.01-2 pts. wt. diluent, 0.1-1 pt. wt. dispersant, 26-85 pts. wt. filler, 0.5-6 pts. wt. anti-settling agent and 0.5-6 pts. wt. graphene; (2) preparation of epoxy resin anticorrosive coating, which involves (1) mixing graphene, diluent, epoxy resin and dispersant to obtain graphene resin dispersion liquid, (2) mixing the graphene resin dispersion liquid, diluent and filler, grinding to obtain slurry and (3) mixing the slurry, anti-settling agent, mica iron oxide red and diluent; and (3) anticorrosive coating, which comprises primer coating, intermediate paint coating and topcoat coating.
