NOVELTY - Graphene silane coating agent comprises 0.08-0.18 wt.% modified graphene, 0.6-1.1 wt.% silane coupling agent, 0.3-0.8 wt.% adhesion promoter, 1.6-2.2 wt.% complex, 0.8-1.0 wt.% fluoride, and rest is water. USE - Graphene silane coating agent. ADVANTAGE - The graphene silane coating agent has good adhesive force, graphene-silane hybrid film and good corrosion resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene silane coating agent, which involves: (A) adding 1/5-1/4 of water in the reaction kettle, adding modified graphene, and stirring for 2-3 hours; (B) adding silane coupling agent, adhesion promoter, and stirring for 7-8 hours; (C) adding fluoride, and stirring for 0.5-1 hours; (D) adding complex, and stirring for 2-3 hours; and (E) supplementing remaining water, and stirring uniformly.
