Abstract
The invention discloses an environment-friendly silver electroplating technique which comprises the following steps: 1. chemical deoiling; 2. chemical derusting: soaking in a deruster; 3. water washing; 4. nickel preplating: soaking a metal part in a nickel plating solution; 5. activating treatment; 6. pulse silver plating: soaking the metal part in a silver plating solution, of which the current density is 2-5 A/dm<2>, the pH value is 5-6 and the temperature is controlled at 25-30 DEG C, for 5-10 seconds; 7. passivating treatment; and 8. drying and packaging. The technique is reasonable, and reduces the injury to the operating personnel due to the adoption of the cyanide-free formula which is environment-friendly and pollution-free; and the produced product has the advantages of favorable smoothness and uniform crystallization.
Description
Technical field
The invention belongs to the electroplating chemical technical field, be specifically related to a kind of environment-protection electroplating silver process.
Background technology
Argent have good electroconductibility weldability and contact resistance low, be widely used on high-end electronic component, appliance contact, valuable instrument, present direct current electrode position silver process adopts prussiate to electroplate mostly, prussiate has severe toxicity and to damage operator's physical and mental health to environment, the cyanogenless electroplating technology of use is also arranged at present but exist the low crystallization of light inhomogeneous, plating solution is unstable.
Summary of the invention
The object of the present invention is to provide a kind of technique reasonable, environment friendly and pollution-free harmless to operator safety, the environment-protection electroplating silver process that the product performance of producing are stable.
Technical solution of the present invention is:
A kind of environment-protection electroplating silver process, it is characterized in that: comprise the following steps, 1, electrochemical deoiling, 2, chemical rust removing, namely use rust remover to soak, 3, washing, 4, nickel preplating is about to metalwork and puts into nickel plating solution and soak, and 5, activation treatment, 6, pulse silver-coating is about to metalwork and puts into current density 02-5A/dm
2, pH value 5-6, temperature be controlled in the silver plating solution of 25-30 ° of C, the immersion time is 5-10S, 7, Passivation Treatment, 8, drying and packaging.
Described silver plating solution is: Silver Nitrate 40-80g/L, and Sulfothiorine 200-300g/L, potassium pyrosulfite 50-100g/L, citric acid 10-50g/L, potassiumiodide 20-50g/L, thiocarbonyl compound 5-10g/L, surplus is the mixture of distilled water.
Technique of the present invention is reasonable, and employing is environment friendly and pollution-free without the cyanogen formula, reduces the infringement to operator, and the good crystallization of the product glossiness of producing is even.
