Abstract
The invention discloses an environmental-friendly electrosilvering solution, and the environmental-friendly electrosilvering solution is prepared from the following components in percentage by weight: 40-80 g/L of silver nitrate, 200-300 g/L of sodium thiosulfate, 50-100 g/L of potassium metabisulfite, 10-50 g/L of citric acid, 20-50 g/L of potassium iodide, 5-10 g/L of carbonyl compound and the balance of distilled water. By adopting the environmental-friendly electrosilvering solution, a formula is reasonable, the adopted cyanide-free formula is environmental-friendly and does not pollute the environment, damages to an operator are reduced, the brightness of a plated product is good, and the uniform bonding strength of the plated product is strong.
Description
Technical field
The invention belongs to the electroplating chemical technical field, be specifically related to the silver-plated solution of a kind of environmental protection electric.
Background technology
Argent have good electroconductibility weldability and contact resistance low, be widely used on high-end electronic component, appliance contact, valuable instrument, the silver-plated most employing prussiate of present direct current is electroplated, prussiate has severe toxicity and to damage operator's physical and mental health to environment, the cyanideless electro-plating 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 formula reasonable, bath stability is environment friendly and pollution-free, the silver-plated solution of environmental protection electric that the good bonding strength of the product luminance brightness of producing is high.
Technical solution of the present invention is:
A kind of plating plating silver solution, it is characterized in that: by following composition by weight proportion proportioning form, Silver Nitrate 40-80g/L, Sulfothiorine 200-300g/L, potassium pyrosulfite 50-100g/L, citric acid 10-50g/L, potassiumiodide 20-50g/L, thiocarbonyl compound 5-10g/L, surplus distilled water.
The present invention fills a prescription rationally, and employing is environment friendly and pollution-free without the cyanogen formula, reduces the infringement to operator, and the good even bonding strength of the product luminance brightness of plating is high.
Embodiment:
