Abstract
The invention discloses a barrel nickel plating softening agent and a preparation method thereof. The barrel nickel plating softening agent comprises: 30-60g/L of sodium saccharin, 0.5-5g/L of sodium propynesulfonate, 0.1-1g/L of sodium 2-ethylhexyl sulfate, 0.01-0.5g/L of carboxyethyl isothiourea inner salt, 20-50g/L of sodium allylsulfonate, 0.01-1g/L of isothiourea propanesulfonic acid inner salt and the balance of pure water. The preparation method of the barrel nickel plating softening agent is simple and easy to operate; the prepared barrel nickel plating softening agent has the characteristics of low consumption, ability of effectively improving the softness of a plated layer, and good walking and plating effects.
Description
Technical field
The present invention relates to electroplating technology field, more particularly, particularly relate to a kind of barrel nickel plating softening agent and compound method thereof.
Background technology
Nickel plating brightener, through the development of many decades, was generally divided into for four generations at present: first-generation nickel plating brightener is based on metal-salt; Second is combined into master on behalf of Isosorbide-5-Nitrae-butynediol and asccharin; The third generation is epoxy compounds and the asccharin of Isosorbide-5-Nitrae-butynediol; Forth generation is most typical representative with the combination of pyridine derivate and ynamine compounds and propiolic alcohol derivative and softening agent.In this several generations nickel plating brightener, third and fourth generation nickel plating brightener and its intermediate in close relations.
Softening agent is a kind of electroplating additive reducing or eliminating coating fragility, and the fragility of coating causes because coating internal stress is unbalanced to a great extent, and therefore softening agent is alternatively internal stress remover.Asccharin (or soluble saccharin) in such as bright nickel plating is exactly a kind of softening agent.Why softening agent can reduce or eliminate the internal stress of coating, because this kind of additive can change the direction of coating stress in electrodeposition process, thus between stress and tension stress, reach certain balance, macroscopically playing the effect relaxing coating stress.
In nickel plating technology, the use consumption of softening agent determines nickel plating cost on the one hand, and the formula of softening agent directly affects plating effect on the other hand, and softening agent conventional in the market still exists the problem of plating poor effect.
Summary of the invention
The object of the invention is to, a kind of low consumption amount is provided, effectively can increase the flexibility of coating and walk, barrel nickel plating softening agent that plating is effective and compound method thereof.
For achieving the above object, present invention employs following technical scheme:
A kind of barrel nickel plating softening agent, raw materials used and content is as follows: soluble saccharin: 30 ~ 60g/L, propine sodium sulfonate: 0.5 ~ 5g/L, 2-ethylhexyl sodium sulfate: 0.1 ~ 1g/L, propyloic isothiourea inner salt: 0.01 ~ 0.5g/L, propenyl sodium sulfonate: 20 ~ 50g/L, isothiourea propanesulfonic acid inner salt: 0.01 ~ 1g/L, pure water: surplus.
Present invention also offers the compound method of above-mentioned barrel nickel plating softening agent, comprise the steps:
1), in agitation vat, add the pure water of formula ratio 2/3, add soluble saccharin while stirring, to dissolving completely;
2), propine sodium sulfonate, 2-ethylhexyl sodium sulfate, propenyl sodium sulfonate is added successively, to dissolving the main liquid of furnishing completely under whipped state;
3), separately get appropriate warm water and dissolve isothiourea propanesulfonic acid inner salt and propyloic isothiourea inner salt, add after dissolving is good and become owner of in liquid, stir;
4), adjustment pH value is 4.5 ~ 5.0, adds surplus pure water to volume required, finally filters filling, to obtain final product.
Further, above-mentioned steps 3) in use warm water be 20 ~ 60 DEG C.
Barrel nickel plating softening agent of the present invention effectively can increase the flexibility of coating and walk, low consumption amount, reduce coating fragility, coating and fastener body can be made to combine closely; The compound method of barrel nickel plating softening agent of the present invention is simple, easy handling and with low cost.
