Abstract
The invention relates to cyaniding silver plating brightening agent and a preparation method thereof. The brightening agent is characterized by mainly comprising antimony potassium tartrate, imidazole, sodium dodecyl dibenzene sulfonate, polyoxyethylene ether, deionized water and the like. The cyaniding silver plating brightening agent has a bright silver plating coating with uniform plating, fading prevention, high hardness, good wear resistance, and strong bonding force with substrate. Compared with a conventional cyaniding silver plating brightening agent, the operation of the brightening agent has the advantages of high working temperature, wide current density range, good deep plating capability and the like.
Description
Technical field
The present invention relates to a kind of brightening agent for cyaniding plant of silver and preparation method thereof, belong to metal material surface protection field.
Background technology
Silver-plated is a kind of of precious metal electroplating, because the cost of silvered film is lower than Gold plated Layer comparatively speaking, and has very high electroconductibility, light reflective and to the chemical stability of Organic Acid and Base, thereby be widely used in the functional platings such as decorative electroplating electron device, because the in recent years fast development of electronic technology makes functional silver-plated increasing rapidly, at present, the system of the silver-plated application of actual electrical is mainly two large classes, and a class is cyaniding plant of silver and without cyanogen class silver-plated two large classes.Along with people to the improving constantly of environmental consciousness, it is silver-plated that people substitute with serious pollution prussiate in the urgent need to the cyanide-free silver plating process of developing a kind of maturation, this is the main flow direction of future development.But compare with cyaniding plant of silver, the non-cyanide silver coating operating procedure is complicated, cost is higher, especially the stability of the plating bath in the non-cyanide silver coating system and brightening agent thereof fails to be well solved always, be difficult to the long-time continuous operation, so, the prussiate of severe toxicity is silver-plated at present still is the main flow that domestic and international silver plating industry is produced, this is reason on the one hand, also have because traditional silver lustre preparation method plates thick layer silver in basic plating bath, and then polish with the mode of mechanical grinding, this is the wasting manpower and material resources not only, also wastes a large amount of silver in polishing process, and silver-plating brightener then can plate out the silver lustre of specular gloss once, therefore, the research of brightening agent for cyaniding plant of silver also has direct realistic meaning very much.
At present, domestic brightening agent for cyaniding plant of silver exists coating stability lower slightly, and coating is excessively crisp, and the defective such as the coating anti-tarnishing ability is relatively poor, and brightness effect is undesirable.
The invention provides a kind of brightening agent for cyaniding plant of silver and preparation method thereof, solve and overcome present commercial brightening agent for cyaniding plant of silver overwhelming majority sulfur-bearings, in electrodeposition process, easily decompose, the small molecules sulfide that generates can be mixed in the coating, easily make coating color, and the defective that the working current density scope is narrower, service temperature is lower when electroplating.
Summary of the invention
Purpose of the present invention is exactly to be to solve and overcome above-mentioned defective, and a kind of cyaniding plant of silver brightening agent and preparation method thereof is provided.The present invention is achieved through the following technical solutions, it is characterized in that this cyaniding plant of silver brightening agent mainly is comprised of: antimonypotassium tartrate, imidazoles, dodecyl hexichol semi-annular jade pendant acid sodium, Soxylat A 25-7, deionized water etc.
By containing in its every liter plating bath: antimonypotassium tartrate 100～250g/L; Imidazoles 10～20g/L; Dodecyl hexichol semi-annular jade pendant acid sodium 2～5g/L; Soxylat A 25-7 1～5g/L; Surplus is deionized water.
Its preparation method is: with antimonypotassium tartrate 100～250g/L; Imidazoles 10～20g/L; Dodecyl hexichol semi-annular jade pendant acid sodium 2～5g/L; Soxylat A 25-7 1～5g/L is dissolved in the deionized water, is diluted to one liter with deionized water, stirs and namely gets required brightening agent.
Embodiment
1, accurately takes by weighing antimonypotassium tartrate 100g/L; Imidazoles 15g/L; Dodecyl hexichol semi-annular jade pendant acid sodium 2g/L; Soxylat A 25-7 2g/L is dissolved in the deionized water, is diluted to one liter with deionized water, stirs and namely gets required brightening agent.
2, brightening agent provided by the invention is added in the cyaniding plant of silver plating bath electroplate according to a conventional method, can obtain coating even and not easy to change, hardness is higher, wear resistance good, the bright silver plating layer strong with basal body binding force.Compare the advantages such as to have working temperature in operation high, and current density range is wide, and covering power is good with general brightening agent for cyaniding plant of silver.
Claims (3)
1. brightening agent for cyaniding plant of silver and preparation method thereof.It is characterized in that this brightening agent for cyaniding plant of silver.Mainly formed by: antimonypotassium tartrate, imidazoles, dodecyl hexichol semi-annular jade pendant acid sodium, Soxylat A 25-7, deionized water etc.
2. according to right 1 described a kind of brightening agent for cyaniding plant of silver.By containing in its every liter plating bath: antimonypotassium tartrate 100～250g/L; Imidazoles 10～20g/L; Dodecyl hexichol semi-annular jade pendant acid sodium 2～5g/L; Soxylat A 25-7 1～5g/L; Surplus is deionized water.
3. according to right 1,2 described a kind of cyaniding plant of silver electroplate liquids, the preparation method is: with antimonypotassium tartrate 100～250g/L; Imidazoles 10～20g/L; Dodecyl hexichol semi-annular jade pendant acid sodium 2～5g/L; Soxylat A 25-7 1～5g/L is dissolved in the deionized water, is diluted to one liter with deionized water, stirs and namely gets required brightening agent.
