COMPOSITION FOR PROCESSING STEEL OR ZINC-PLATED SURFACE AND METHOD OF ITS FABRICATION Russian patent published in 2013 - IPC C23C22/50 C23C22/53 C23C22/05 C09D1/00 

FIELD: metallurgy.

SUBSTANCE: proposed method comprises mixing components to make protective adhesive coating, processing articles by said composition and drying at 100-150°C. Said composition is made by mixing amino alcohol C₃-C₁₀ and water-dispersed silicon dioxide, an aerosol, at the following molar ratio of amino alcohol:silicon dioxide - 1:1…1:7, heating at 45-55°C and mixing for, at least, 2 h. It is possible to make additional treatment in solution of cerium nitrate (III). Proposed method allows decreasing the number of composition components and composition stability for, at least, 720 h, decreasing composition preparation time to 2 h, and ruling out contamination by heavy metal ions.

EFFECT: antirust protection, adhesion to lacquer coating.
