▎ 摘　　要

NOVELTY - A graphene-modified anticorrosive primer comprises a component (A) and a component (B) in a mass ratio of 3-5:1. The component (A) comprises 25-35 %mass epoxy resin, 35-45 %mass zinc powder, 0.5-1 %mass graphene, 10-25 %mass solvent and 1-5 %mass filler. The component (B) comprises 15-20 %mass n-butanol, 45-60 %mass xylene, 15-20 %mass curing agent and 1-5 %mass additive. USE - Graphene-modified anticorrosive primer. ADVANTAGE - The graphene-modified anticorrosive primer has excellent physical property and electrochemical property (by addition of graphene), and forms ordered protective film having excellent anticorrosive performance, with reduced amount of zinc powder. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene-modified anticorrosive primer, which involves adding epoxy resin to a stirring container, uniformly stirring, adding zinc powder, solvent, graphene and filler, stirring, grinding obtained mixture, obtaining component (A), mixing xylene and n-butanol, adding curing agent and additive, stirring, obtaining component (B), and mixing the component (A) and the component (B).
