Composition for surface treatment of steel sheet with acid resistance
The granted patent (Publication Number: US11939489B2) discloses a solution composition for the surface treatment of a steel sheet. The composition includes colloidal silica with 5 to 20 nm-sized silica particles, silane with three or more alkoxy groups, an acrylate-based organic monomer, acid, an organic resin with a cyclic ring structure, and a solvent. The acidity of the solution falls within a pH range of 1 to 5. The organic resin with a cyclic ring structure can be polyurethane, an amino-modified phenolic resin, a polyester resin, polyvinyl butyral, or a hybrid resin of two or more of these options.
Furthermore, the composition specifies the percentage range of each component, such as 30 to 50 wt % of colloidal silica, 40 to 60 wt % of silane, 5 to 15 wt % of the organic monomer, 0.01 to 1 wt % of acid, 0.1 to 5.0 wt % of the organic resin, and 1 to 15 wt % of the solvent. The colloidal silica is required to have a silica content of 10 to 45 wt %. The silane component includes various options like vinyl trimethoxy silane, 3-methacryloxypropyl silane, and tetraethoxysilane. The organic monomer can be acrylic acid glacial, methyl acrylate, or other specified options. The acid component can be acetic acid, sulfuric acid, or other acids listed. The solvent component includes options like methanol, ethanol, and 2-propanol, among others.
