Description
Technical field
The invention belongs to brightener fields, and in particular to a kind of preparation method of brightener.
Background technology
Such as plastic cement, optical glass lens, metal product in industrial trade（Copper, iron, aluminium, steel, zinc, alloy）Etc. various materials
Generally required when material cleaning areal stretch oil, cutting oil, antirust oil, lubricating oil, various greasy dirts, spot, the grease such as punching oil into
Row cleaning, mostly uses greatly diesel oil, coal Water Oil Or Gas cleans part as cleaning solution.This not only waste of energy, and there is potential
Insecurity, it is careless slightly, then may lead to fire.In addition cleaning agent used itself but there is prodigious defect,
Quality height differs, and whole detergency ability is poor, is easy to cause corrosion harmfulness to human body, safety is low, and decontamination rear surface
Color is poor.Therefore, last layer brightener is plated on the surface of metal product, thus difficult to understand can ensures that metal is not easy by greasy dirt institute
Pollution, and ensure that the aesthetics of metal product.
Brightener is a kind of additive for being added on and obtaining bright depth in plating solution.Brightener has good inside and outside lubrication
Performance and surface light are benign, while having good intersolubility and antistick characteristic, and the vividness and brightness of color masterbatch can be improved.With
The development of science and technology, brightener is also applied in more and more industries and come.Obtain bright coating, the selection of brightener
It is the key that technique, it should have：（1）Preferable bath stability can keep certain deposition rate and service life；（2）
There is significant light enhancing effect to coating；（3）The original performance of coating will not be reduced；（4）Raw material composition is simple, and affordable is easy to
It promotes the use of.But since chemical nickel plating system operation temperature is generally higher, and matrix surface largely, will be analysed constantly in plating solution
Go out hydrogen, especially different from plating, matrix is not thus cathodically polarised, and brightening agent cannot be applied directly in chemical plating,
Thus select suitable chemical plating brightener particularly significant.
It is acid chemical plating nickel-phosphorus alloy brightener to study and apply more at present, is suitable for alkaline chemical nickel-plating tungsten
The brightener of phosphorus alloy is very few or ineffective.In addition, the addition of brightener is added using independent in the prior art,
Brightness is obtained with this.But individually addition brightener does not allow manageability, tank liquor often to generate variation yet, will appear certain often
A kind of substance is higher or relatively low, quality declines, coating be susceptible to burn, bright striped and phenomena such as rough surface.
In summary, brightener nowadays in the market is primarily present defect below：The addition of existing brightener
All it is that brightness is obtained with this using individually addition.Can cause can coating be susceptible to burn, bright striped and rough surface
Phenomena such as.Therefore, the good environment protection brilliant agent of research effect is very necessary.
