Abstract
The invention discloses a non-cyanide electrosilvering solution consisting of the following ingredients according to a weight ratio: 30-60 g/L of silver nitrate, 150-300 g/L of sodium thiosulfate, 20-100 g/L of potassium metabisulfite, 10-50 g/L of citric acid, 5-10 g/L of polyoxyethylene fatty alcohol ether, and the balance of distilled water. The non-cyanide electrosilvering solution disclosed by the invention adopts a reasonable formula, is environmentally-friendly and non-pollution by virtue of the non-cyanide formula, alleviates harms on an operator, and ensures high brightness of a product plating layer, uniform crystallization and high combination strength.
Description
Technical field
The invention belongs to the electroplating chemical technical field, be specifically related to a kind of non-cyanide silver electroplating solution.
Background technology
Metal is silver-plated have good electroconductibility weldability and contact resistance low, be widely used on high-end electronic component, appliance contact, valuable instrument, present electrosilvering generally adopts and contains cyanogen process, and is physically and mentally healthy to environment and infringement operator.
Summary of the invention
The object of the present invention is to provide a kind of formula reasonable, environment friendly and pollution-free, operational safety, the non-cyanide silver electroplating solution of simple process.
Technical solution of the present invention is:
A kind of non-cyanide silver electroplating solution is characterized in that: by following composition by weight proportion proportioning form, Silver Nitrate 30-60g/L, Sulfothiorine 150-300g/L, potassium pyrosulfite 20-100g/L, citric acid 10-50g/L, polyoxyethylene aliphatic alcohol ether 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 product coating luminance brightness is good, and the even bonding strength of crystallization is high.
