Abstract
The invention discloses a method for preventing color change of a copper ornament plated with silver and relates to the technical field of electroplating. The method includes the following steps that A, the copper ornament plated with silver is soaked in pure water and then aired for use; B, a silver plating color change preventing agent is added to the pure water according to the amount of 15 ml/L to 30 ml/L and stirred evenly, the mixture is heated to be at the temperature of 50 DEG C to 60 DEG C, and the copper ornament is placed in the mixture, soaked for 3 min to 5 min, taken out and then spin-dried through a centrifugal machine. Compared with the prior art, the problem that a silver-plated layer is corroded and discolored due to cyanide remaining on the copper ornament can be solved.
Description
Technical field
The present invention relates to electroplating technology field, especially a kind of for copper decorations silver-plated after the method preventing variable color.
Background technology
Copper-made ornament on the make will be electroplated into required color as required, not only can increase the pattern of ornaments at copper-made ornament electroplate, can also increase the weldability of copper-made ornament; If copper-made ornament does not wash clean at silver-plated rear water, the upper residual prussiate of copper decorations is easy to cause silvered film corrosive chameleon.
Summary of the invention
Technical problem to be solved by this invention is to provide the method for the silver-plated rear Anti-tarnishing of a kind of copper decorations, adorns the upper problem remaining prussiate and cause very much silvered film corrosive chameleon to prevent copper.
The technical scheme that technical solution problem of the present invention adopts is: the method for the silver-plated rear Anti-tarnishing of a kind of copper decorations, comprises the following steps:
A, the copper decorations pure water after silver-plated is embathed after dry, for subsequent use;
B, silver plating anti-color changing agent to be added in pure water by the amount of 15ml/L ~ 30ml/L and stir, be heated to 50 DEG C ~ 60 DEG C, put into described copper decorations, soaks 3 minutes ~ 5 minutes, taking-up, dries with whizzer.
Above-mentioned copper is adornd in silver-plated cyaniding silver leaching process technical scheme, technical scheme can also be more specifically: described silver plating anti-color changing agent is made up of the component of following weight percent: tert-dodecyl mercaptan 5 parts ~ 6 parts, polyvinyl alcohol 8 parts ~ 10 parts, dehydrated alcohol 8 parts ~ 10 parts, ethylene glycol part 10 parts ~ 12 parts, phenylpropyl alcohol triazole 3 parts ~ 5 parts, fatty alcohol-polyoxyethylene ether 12 parts ~ 15 parts, surplus is deionized water.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect: the agent of this silver plating anti-color changing can form the protective layer of one deck about 0.5 millimeter on copper decorations surface, can effectively prevent silvered film variable color.
