▎ 摘  要

NOVELTY - An anti-rust color paste comprises 45-65 %mass, preferably 50 %mass pigment, 4-7 %mass, preferably 5.5 %mass wetting and dispersing agent, 5-10 %mass, preferably 7.5 %mass humectant, 0.05-0.1 %mass, preferably 0.06 %mass stabilizer, 0.01-0.5 %mass, preferably 0.25 %mass defoamer, 1-2 %mass, preferably 1.6 %mass acid complexing agent, 0.05-0.3 %mass, preferably 0.15 %mass fungicide, 0.2-0.3 %mass, preferably 0.25 %mass pH adjusting agent and 10-40 %mass, preferably 25 %mass deionized water. The stabilizer is graphene oxide. USE - Anti-rust color paste for aqueous industrial coating such as alkyd primer and epoxy ester primer. ADVANTAGE - The anti-rust color paste is environmentally-friendly and has excellent compatibility. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of anti-rust color paste, which involves (S1) adding stabilizer to deionized water, and mixing to prepare pre-solution, (S2) adding dispersing agent, humectant, fungicide, acid complexing agent, transforming agent and defoamer to pre-solution, stirring, (S3) adding nano titanium dioxide and carbon black powder, stirring, (S4) adding obtained mixed slurry component to grinder, grinding, until uniform slurry with excellent fluidity is formed, (S5) adding appropriate amount of pH adjusting agent to adjust the pH of slurry.
