| titleOfInvention | A kind of cyanide-free silver plating brightener and preparation method thereof |
| abstract | The invention relates to the technical field of cyanide-free silver-plating, in particular to a cyanide-free silver-plating brightener and a preparation method thereof. Deionized water is used as a solvent, and the components comprise the following concentrations: sodium dodecyldibenzenesulfonate 10 ～25g/L, HEDTA 1～2.5g/L, stabilizer 0.5～2.0g/L, dispersant 20～35g/L, urea 10～20g/L, 1‑benzyl‑1,2,3,4‑ 10-15 g/L of tetrahydroisoquinoline, 30-45 g/L of sulfur-containing heterocyclic compound. The cyanide-free silver-plated brightener of the invention can change the crystal orientation of the coating layer, significantly refine the crystal grains, and the obtained coating layer has obvious wear resistance and bright effect, and is not easily affected by the current density. |
