Description
Technical field
The present invention relates to a kind of preparation method of thermal isolation film, more particularly to the making side of silver-colored light reflective surface on electro-plating method
Method, belong to light industry technical field.
Background technology
Current reflective membrane is using more and more extensive, and reflection and heat insulation film is effectively to prevent strong light from attacking protection object
Fire hot, oldization, go bad.And it is then the method for most saving reflective surface metal to electroplate reflective membrane.
It is exactly to plate the other gold of a thin layer on some metal surfaces using electrolysis principle to electroplate (Electroplating)
The process of category or alloy, it is the technique for the surface attachment layer of metal film for making metal or other materials product using electrolysis
Prevent metal from aoxidizing so as to play（Such as corrosion）, improve wearability, electric conductivity, reflective, corrosion resistance (copper sulphate etc.）And increase
Enter attractive in appearance wait to act on.The outer layer of many coins is also plating.
During plating, coated metal or other insoluble materials do anode, and workpiece to be plated does negative electrode, coated metal
Cation is reduced to form coating in workpiece surface to be plated.To exclude the interference of other cations, and make coating uniformly, firmly,
Electroplate liquid need to be done with the solution of the cation containing coated metal, to keep the concentration of coated metal cation constant.The purpose of plating
It is that the coat of metal is plated on base material, changes substrate surface property or size.Plating can strengthen the corrosion resistance (coating of metal
Metal uses corrosion resistant metal more), increase hardness, prevent from wearing away, improve electric conductivity, slickness, heat resistance and surface U.S.
See.
Gold that attachment is good but that performance is different with matrix material are deposited on machinework using electrolytic cell principle
Belong to the technology of coating.Electrodeposited coating is more uniform than hot dipping layer, typically all relatively thin, from several microns to tens microns.Pass through electricity
Plating, the superficial layer of decoration protectiveness and various functions can be obtained on machinework, abrasion can also be repaired and processing is lost
Workpiece by mistake.
The electrolyte solution that anode and cathode is formed with the cation of the metal plated up is connected.Pass to the power supply of direct current
Afterwards, the metal of anode can aoxidize（Lose electronics）, the cation in solution is then in cathodic reduction（Obtain electronics）Into atom simultaneously
Accumulate in negative electrode top layer.
The aesthetic property of object and size of current are plated after plating relation, and electric current is smaller, and the object being plated will be got over
It is attractive in appearance；Shape on the contrary then that some out-of-flatnesses occur.The main application of plating include prevent metal oxidation (such as corrosion) with
And decorated.The outer layer of many coins is also plating.
Sewage caused by plating（Such as lose the electrolyte of effectiveness）It is the important sources of water pollution.Electroplating technology is wide
Technique of the general use in semiconductor and microelectronic component lead frame.
Plating needs a low-voltage high-current power source powered to electroplating bath and by electroplate liquid, part to be plated (negative electrode) and sun
The electrolysis unit that pole is formed.Wherein electroplating bath components are different and different regarding coating, but containing the main salt for being provided with metal ion, energy
Be complexed the complexing agent that metal ion in main salt forms complex compound, for the buffer of stablizing solution acid-base value, anode activation agent and
Special additive (such as brightener, grain refiner, leveling agent, wetting agent, stress elimination agent and fog inhibitor).Electroplating process
Be the metal ion in plating solution in the presence of external electric field, be reduced into metallic atom through electrode reaction, and gold is carried out on negative electrode
Belong to the process of deposition.Therefore, this is a metal electrodeposition mistake for including the steps such as mass transfer in liquid phase, electrochemical reaction and electrocrystallization
Journey.
In the coating bath of electroplate liquid is filled, by clearing up the unplated piece with special pre-treatment as negative electrode, metal lining is used
Anode is made, the two poles of the earth couple with the positive pole and negative pole of dc source respectively.Electroplate liquid by the compound containing metal lining, lead
The aqueous solution composition of salt, buffer, pH adjusting agent and the additive of electricity etc..After energization, the metal ion in electroplate liquid,
It is moved in the presence of potential difference on negative electrode and forms coating.The metal of anode forms metal ion and enters electroplate liquid, to keep quilt
The concentration of the metal ion of plating.In some cases, such as chromium plating, be using insoluble anode made of lead, lead-antimony alloy, it
Only play a part of to transmit electronics, conducting electric current.Chromium ion concentration in electrolyte, it need to rely on and chromaking is regularly added into plating solution
Compound maintains.During plating, the quality of anode material, the composition of electroplate liquid, temperature, current density, conduction time, stirring are strong
Degree, the impurity separated out, power supply wave shape etc. all can influence the quality of coating, it is necessary to be controlled in good time.
The content of the invention
