| titleOfInvention | A kind of gold immersion solution for cyanide-free chemical precipitation of thick gold and process thereof |
| abstract | The invention discloses a cyanide-free chemically heavy gold immersion gold solution and a process thereof, which are composed of the following components: cyanide-free gold salt, calculated as 16-20g/L in terms of Au ion content; and 50-100g of complexing agent /L; buffer is 10-50g/L; composite reducing agent is 1-5g/L; surfactant is 0.5-1g/L; composite stabilizer is 10-20mg/L; corrosion inhibitor is 5-10mg/L L; the reaction accelerator is 40-80mg/L, and the silver ion is 0.5-1mg/L; the composite reducing agent is composed of sodium borohydride, glucose and hydroxylamine sulfate, and the sodium borohydride, glucose and hydroxylamine sulfate The mass concentration ratio of the three is 2:2:1; the composite stabilizer is composed of antimony potassium tartrate, hyperbranched urethane sulfonate and polyacrylamide, and the mass concentration ratio of the three is 2:1:1; the The concentration ratio of the corrosion inhibitor and the reaction accelerator when used is 1:8. The gold coating obtained by the invention has good adhesion, uniform coating and fast deposition rate. |
