Abstract
The invention provides an auxiliary additive for a chloride or sodium chloride galvanizing process. The auxiliary additive is characterized by being prepared from the following components in concentration by mass: 1.0-2.0g/L of nicotinic acid, 0.4-0.8g/L of polyvinyl pyrrolidone, 2.0-4.0g/L of sodium propyne sulfonate, 2-6.0g/L of edible saccharin and the balance of ethanol and deionized water. The auxiliary additive has an auxiliary effect on a main brightener, and has an effect of making up for light in high and low current density regions, does not contain surfactant, is mild in composition and does not generate foam; the production process is optimized and the pollution to water sources, soil and the like is avoided.
Description
Technical field
The present invention relates to Repone K or sodium chloride electrolysis method galvanizing technique field, refer to a kind of supplementary additive for Repone K or zinc electroplating in soidium chloride technique particularly.
Background technology
Without the Repone K under the sour environment of cyanogen or Sodium Chloride Based Bright Zinc Plating from last century the seventies by Japanese invention, since importing China into subsequently, the history of existing 40 years.The advantages such as it has cathode efficiency high (efficiency is up to 95%), sedimentation velocity is fast, dispersive ability good, the luminance brightness of coating luminance brightness similar plating Cr technique, plating solution operating environment condition (as temperature, current density) are wider, therefore enjoy great popularity.Domestic in China, in whole zinc-plated (alkali zinc or sour zinc) technique, Repone K or sodium-chlor account for 25% ~ 30% of technique as plating solution, reach 6800 ~ 13,000 ten thousand liters, the brightener of consumption more than about 600 ~ 8,000,000 tons/year.
But, in the prior art, in acid chlorization potassium or zinc electroplating in soidium chloride technique, there is major defect.Brightening agent conventional in this technique is benzylideneacetone, o-chlorobenzaldehyde or the two combine mixed mixture, these aromatic aldehydes, ketone have very strong irritating smell, damage the skin of operator, eyes, these aromatic aldehydes, ketone is insoluble to galvanizing flux, must first with the surfactant of 10 ~ 15 times (as OP-10 ~ 21 or polyalcohols, ether etc.) by these aromatic ketones, can use after aldehyde carries out sufficient emulsification, and in use, also need the supplementary additive (also known as softening agent) matched with it, and also containing a large amount of in these supplementary additives, the surfactant that foam very enriches, fragility is large owing to being mingled with surfactant in a large number for electro-galvanized layer, and the bonding force between workpiece substrate is poor, thus cause zinc coating to decline to the corrosion stability of workpiece, secondly in the cleaning process of electro-galvanized layer, because electro-galvanized layer surfactant foam is too many, a large amount of water need be used, and be difficult to clean up, have impact on bright dipping subsequently, the operations such as passivation, simultaneously, when to zinc bath process, can produce a large amount of with enriching foam, reluctant waste water, water source and soil is caused to be subject to serious pollution.
Summary of the invention
The object of the invention is according to above-mentioned deficiency, a kind of supplementary additive for Repone K or zinc electroplating in soidium chloride technique is provided, itself and main brightener are made multibrightener and are applied, main brightener is helped out, play in high and low current density district and make up light effect, moiety is water-soluble, does not produce foam, optimized production process, does not cause the environmental pollution such as water source and soil.
The present invention is achieved in the following ways: a kind of supplementary additive for Repone K or zinc electroplating in soidium chloride technique, is characterized in that: described supplementary additive comprises the following each component of mass concentration:
A kind of method preparing the supplementary additive for Repone K or zinc electroplating in soidium chloride technique described above, it is characterized in that: first by described nicotinic acid and polyvinylpyrrolidone mixing, ethanol as solvent dissolves, add described propargyl sodium sulfonate and edible asccharin again, and add deionized water to liter, the mass concentration of each component is as follows, the mass concentration of described nicotinic acid is 1.0 ~ 2.0g/L, the mass concentration of described polyvinylpyrrolidone is 0.4 ~ 0.8g/L, described propargyl sodium sulfonate mass concentration is 2.0 ~ 4.0g/L, the mass concentration of described food flavour is 2.0 ~ 6.0g/L.
Preferably, the mass concentration of described nicotinic acid is 1.5g/L, and the mass concentration of described polyvinylpyrrolidone is 0.4g/L, and described propargyl sodium sulfonate mass concentration is 4.0g/L, and the mass concentration of described food flavour is 4.0g/L.
