▎ 摘  要

NOVELTY - Graphene film comprises 80-100 pts. wt. epoxy resin, 4-8 pts. wt. wetting and dispersing agent, 2-4 pts. wt. leveling agent, 2-4 pts. wt. defoamer, 4-10 pts. wt. thixotropic agent, 10-15 pts. wt. graphene, 30-40 pts. wt. xylene and 14-20 pts. wt. n-butanol. The second component is an organically modified amine curing agent. The epoxy value and amine value for compound calculation and the mass ratio of the first component to the second component is 10:2-3. USE - Used as graphene film. ADVANTAGE - The film improves the salt-fog resistance of the paint film. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene film comprising (1) adding thixotropic agent in epoxy resin and mixing uniformly to obtain the mixed material 1, orderly adding graphene in the mixed material 1, wetting dispersant, flatting agent and antifoaming agent, mixing uniformly and grinding to obtain the mixed material 2, adding xylene and n-butyl alcohol in the mixed material 2 and mixing uniformly, filtering the 60-80 mesh to obtain the component A, (2) using organic modified amine curing agent under 60-80 meshes screen filter to obtain the component B, uniformly mixing and dispersing the component A and the component B prepared in step (1) and spraying or brushing to obtain the graphene film.
