In basic solution, the dispersive ability of the surfaceness of additive to affect electroplated zinc nickel alloy, brass coating, homogeneity and solution and covering power.Additive is by improving cathodic polarization but grain refining, and when the grain refining of coating was arrived less than wavelength of visible light, light just diffusion can not take place, and makes coating seem very bright.Zinc-nickel alloy, brass-plating additive mainly utilize the principle of basic solution zinc-plating additive and nickel plating additive, copper plating additive, the basic solution zinc-nickel alloy of preparing by optimizing integration, brass additive, thus reach the purpose that reaches light in basic solution when admiro, brass are electroplated.Find by literature search; Zhou Xiaorong; Li Huafeng; people such as Liu Liming are " electroplating the research of black bright admiro " in the alkaline system; (material protection; vol.32; No.5,1999,1-3) with Zhang Baocheng chief editor " electroplating technology " (press of BJ University of Aeronautics ﹠ Astronautics; Beijing; 1993) the 199th page of additive that all is respectively basic solution brass plating and admiro with trolamine, but trolamine additive weak point is that uneven coating is even in two kinds of electroplating processs, and coating is loose; poor bonding strength; the luminance brightness of coating is not high, and the covering power of solution is poor.
Summary of the invention
Purpose of the present invention overcomes the above-mentioned defective of prior art, the binder component and the compound method thereof of a kind of basic solution electroplated zinc nickel alloy, brass are provided, make homogeneity, compactness and the luminance brightness of coating, all improve a lot with high base strength, and reduced the cost of additive.
The present invention is achieved by the following technical solutions, electroplating solution weight percentages of components of the present invention is: elementary brightening agent: 32-36.5%, elementary brightening agent is a tonka bean camphor, 1,4 butynediol, para toluene sulfonamide, benzene sulfinic acid sodium salt, thiocarbamide 1: 1: 1: the mixture that obtains at 1: 1 a kind of, second-class brightener: 62.5-67%, second-class brightener is a kind of of trolamine, thanomin, Vanillin mixture, tensio-active agent: 0.5-1%, tensio-active agent are a kind of of sodium lauryl sulphate, Sodium dodecylbenzene sulfonate.
Basic solution electroplated zinc nickel alloy of the present invention, brass additive, the last adding in alkali zinc nickel alloy, brass electroplating liquid process for preparation.Additive is to utilize effect of electric field, is adsorbed in metal base surface and influences zinc, nickel or cupric ion deposition process to realize.Add in basic plating admiro or the brass plating bath, can obtain light, densification and uniform zn-ni alloy deposits or brass coating.
The preparation method of basic solution electroplated zinc nickel alloy of the present invention, brass additive, specific as follows: as at first to measure the trolamine of calculated amount, Vanillin with graduated cylinder, thanomin, again according to thanomin, Vanillin, the order of trolamine mixes the three, is stirred to evenly, obtains mixing solutions; Use a small amount of anhydrous alcohol solution tonka bean camphor and thiocarbamide then, add a small amount of distilled water, add tosic acid amine and benzene sulfinic acid sodium salt and sodium lauryl sulphate or sodium laurylsulfonate again, obtain mixing solutions; Mix above-mentioned two mixing solutionss stand-by at last.When the preparation electroplating solution, add by calculated amount.
Describedly measure the trolamine of calculated amount with graduated cylinder, Vanillin, thanomin, by trolamine: Vanillin: thanomin is 10: the volume ratio of 1-4: 10-12 is measured.A small amount of anhydrous alcohol solution tonka bean camphor of described usefulness and thiocarbamide, tonka bean camphor and thiocarbamide weight ratio are 1: 2.The distilled water of described adding is more than 80 ℃.Described adding tosic acid amine, benzene sulfinic acid sodium salt, the weight ratio of sodium lauryl sulphate or sodium laurylsulfonate is 200-300: 200-300: 1.Two mixing solutionss by volume 1: 4-6 mixes stand-by.
The present invention has substantive distinguishing features and marked improvement, the present invention adopts the principle of basic solution zinc-plating additive and nickel plating additive, copper plating additive, the basic solution zinc-nickel alloy of preparing by optimizing integration, brass additive, thereby reduced the cost of additive when admiro, brass are electroplated in basic solution, improved efficient, and the homogeneity of coating, compactness and luminance brightness, all improve a lot with high base strength, having played a small amount of additive has higher effect.
