▎ 摘　　要

NOVELTY - Graphene inorganic zinc silicate workshop primer comprises component A and component B, where the component A is composed of 0.2-5 wt.% graphene, 10-30 wt.% diluent, 0.15-2 wt.% dispersant, 0.5-5 wt.% film forming resin, 0.5-3 wt.% anti-settling agent, 5-20 wt.% zinc powder, 30-70 wt.% filler and 0.2-1 wt.% auxiliary agent, and the component B includes 30-50 wt.% ethyl silicate, 0.01-0.1 wt.% catalyst, 3-5 wt.% deionized water and 45-65 wt.% solvent. USE - Used as graphene inorganic zinc silicate workshop primer. ADVANTAGE - The primer has low zinc content and improved coating thickness more than conventional thickness. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing graphene inorganic zinc silicate workshop primer comprising (i) adding graphene into diluent, dispersing agent, and ultrasonicating to obtain graphene dispersion, (ii) adding film-forming resin, anti-settling agent, zinc powder, filler, auxiliary agent, graphene dispersion, and mixing under stirring state to obtain component A, (iii) adding ethyl silicate and solvent into a reaction kettle, stirring uniformly, heating to 40-50 degrees C, slowly dropping mixture of deionized water and catalyst into the reaction kettle, and mixing at 40-50 degrees C to obtain component B, and (iv) adding component B into component A, mechanically stirring, and then grinding to obtain final product; and (2) use method of primer comprising adding primer with diluent to adjust viscosity of the material, and then spraying to sample surface.
