Description
Technical field
The present invention relates to electrochemical technology field, in particular to a kind of tin plating electrolyte and its preparation method and application.
Background technique
Existing domestic electrical system running equipment is just towards high pressure, high frequency, high-power, high current, intelligence and longevity
Life direction is developed, and is based on the good electric conductivity of pure copper material, thermal conductivity and environmental suitability, copper bar is in large scale electrical power unit
It is indispensable fluid conducting material using being also more and more favored.The industrial copper-based material applied in power equipment, is exposed to
Surface easily aoxidizes in air, and oxide seriously affects the electric conductivity of copper-based material.Copper bar, copper sheet in power equipment and
Copper busbar etc., to prevent contact surface from aoxidizing, the workpiece such as flow guiding connector, binding post, device clamp, disconnecting link contact all carried out tin or
The modification of the coats of metal such as tin, but with equipment long-play, workpiece surface will receive extraneous corrosion and pollution, and coating can be by
It is gradually oxidized disappearance, so that workpiece connecting portion contact resistance be caused to become larger, workpiece superheating phenomenon occur causes electric system to be transported
Row equipment breaks down.
Currently, the development equipment state overhauling of State Grid Corporation of China's normalization, power supply unit strict implement equipment state are commented
Valence directive/guide and equipment state overhauling directive/guide, each province, company, city are more and more tighter to the examination of running equipment indices, to equipment O&M
Quality requirement also increase year by year.On the other hand, the processing maintenance cost of the operating facilities of electric system is constantly going up,
Recoverability has been largely fixed its application cost.Extend service life, the drop of power equipment using method appropriate
Low cost economizes on resources, and is always an important research direction.Repair to electric power large scale equipment with sufacing is
Extend the effective ways of service life of equipment, wherein the Brush Electroplating Technique on copper-based material surface is in sufacing to power equipment
Most simply and easily one of the technology repaired, it refers to the technology with brush plating, so that metal is existed by the method for electrochemistry
Instrument surface, which deposits, to be formed new protective layer and carrys out prosthetic appliance, is the technology that equipment continues normal use.Annual flow guiding connector connects
Terminal, device clamp, disconnecting link contact overheating fault account for the 20% of running equipment failure, almost reach during high temperature, high load capacity

On the other hand, Brush Plating tin plating electrolyte is mainly sulfate-sulfuric acid liquid technique, is aided with one or more aryl sodium salts, benzyl third
The adaptive temperature of the auxiliary agents such as ketone, benzaldehyde, these bath systems is lower, when operation temperature is more than 30 DEG C plating solution be easy to become cloudy,
Mist, greyness, pin hole, point is presented in the Deposit appearance of precipitating, acquisition.Meanwhile higher sulfuric acid concentration will lead to aldehydes, ketone
Auxiliary agent generated during cathode hydrogen evolution, cover a large amount of foam, it is suppressed that the cooling effect of plating system, cause deposition when
Crystallization polarization reduces, and coating is gloomy coarse.
In view of this, the present invention is specifically proposed.
