▎ 摘　　要

NOVELTY - A composite paint comprises 40-60 pts. wt. epoxy resin, 0.1-2 pts. wt. graphene, 5-10 pts. wt. nano silicon dioxide, 5-10 pts. wt. acetylene carbon black, 10-30 pts. wt. curing agent, 1-5 pts. wt. antirust additive, 1-5 pts. wt. defoaming agent, 1-5 pts. wt. leveling agent, 2-10 pts. wt. dispersing agent and 80-160 pts. wt. organic solvent. USE - The composite paint is useful in marine (claimed). ADVANTAGE - The composite paint: has excellent corrosion resistance and comprehensive performance and high adherence; and can be prepared by a simple method in an environmentally-friendly manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the composite paint, which involves: (1) uniformly mixing graphene, nano silicon dioxide, acetylene carbon black and organic solvent and dispersing the mixed mixture at a high speed to obtain a graphene-containing slurry; and (2) adding epoxy resin, antirust additive, defoaming agent, leveling agent and dispersing agent to the graphene-containing slurry, uniformly mixing, then adding curing agent, dispersing at a high speed, leaving still and curing to obtain a nano graphene epoxy resin anticorrosive paint as the target product.
