Abstract
A kind of bright tin plating Zinc alloy electroplating solution relates in the plating bath that contains citric acid or its salt and uses brightening agent, electroplates out the processing method of bright tin-zinc alloy electrodeposits.It is characterized in that in containing the red brass plating bath of citric acid or its salt, having added a kind of brightening agent that contains fat amine compound.Use this electroplating solution that adds novel brightening agent, plating piece can be at 0.5～10A/dm
2Obtain the tin-zinc alloy electrodeposits of light in the current density range.
Description
The present invention relates in the plating bath that contains citric acid or its salt, use brightening agent, electroplate out the processing method of bright tin-zinc alloy coating.
Tin-zinc alloy coating has been widely used for protecting the corrosion of ferrous materials, and has good welding property, can be used as for cadmium coater.
Tin-zinc alloy plating bath commonly used has these plating baths such as prussiate, pyrophosphate salt, fluoroborate and gluconate to have a common shortcoming to be: the alloy composition of tin-zinc coating is subjected to the influence of current density and changes a lot in quite wide scope.The current efficiency of fluoroborate and prussiate plating bath is not high, and needs its waste water is handled.
In order to overcome these shortcomings, russian patent U.S.S.R No.293876 has proposed with citric acid or its salts solution electrodepositing tin-zinc alloys.In this plating bath, add dextrin and gelatin as brightening agent, can obtain tin-zinc alloy coating, but this coating is brightless than fine crystallization.In order to improve the clear 51-75632 of luminance brightness day disclosure special permission communique a kind of tin-zinc brightening agent has been proposed.This brightening agent is made up of with the aqueous solution of phthalic acid reaction and aromatic aldehyde the reaction of aliphatic amide and acylate again.Its advantage is the tin-zinc alloy coating that can obtain light or half light, and shortcoming is the working current density narrow range.U.S. Pat P4168223 has proposed a kind of brightening agent, the combination of promptly a kind of water-soluble polymkeric substance and aldehyde compound.This polymkeric substance can be a polyoxyethylene, the reaction product of a kind of and epoxy compounds in polyoxyethylene deriv or ethylene glycol, propylene glycol, the glycerine.This brightening agent also can obtain the tin-zinc alloy coating of light or half light.Shortcoming remains the working current density narrow range.
Purpose of the present invention is exactly in order to obtain the tin-zinc alloy coating of light or half light in the current density range of broad.
The object of the present invention is achieved like this: the additive that adds following type in the plating bath of citric acid or its salt:
Additive 1: amine compound.This compound is selected from quadrol, Diethylenetriamine, three second tetramines, tetraethylene-pentamine, many second polyamines etc., and add-on is 1～10 grams per liter.
Additive 2: the reaction of aliphatic amide and acylate, again with the aqueous solution of phthalic acid reaction product.As quadrol, 1.6-hexanediamine, dimethyl malonate, Succinic acid dimethylester, ethyl succinate, diethylene adipate, Tetra hydro Phthalic anhydride etc.
Additive 3: water-soluble polyoxyethylene compound or polyoxyethylene deriv.As polyoxyethylene glycol, peregal, OP type emulsifying agent etc.
Additive 4: aldehyde compound.As piperonylaldehyde, aubepine, phenyl aldehyde etc.
Brightening agent can be an additive 1,2, and 4 combination also can be by additive 1,3, and 4 form or by additive 1,2,3,4 form.
The present invention further makes an explanation by following example:
Plating bath is formed:
Triammonium citrate ((NH
4)
3C
6H
5O
7) 0.5mol/l
Stannous sulfate (SnSO
4) 0.1mol/l
Zinc sulfate (ZnSO
47H
2O) 0.2mol/l
Sulfuric acid amine ((NH
4)
2SO
4) 0.6mol/l
PH value 5～6
20 ℃ of temperature
With 267 milliliters of Hull Cells with 250 ml solns at copper or the enterprising electroplating of iron-based body, plating strength of current is 2A, plating time is 4 minutes.
Additive A: ethyl succinate 15.5 gram adds quadrols 5 grams 80～90 ℃ of following insulated and stirred 30 minutes, add 1.6-hexanediamine 10 grams again, stirred under the equality of temperature 30 minutes, and added Tetra hydro Phthalic anhydride 20 grams then, add 200 milliliters in water at last 93～97 ℃ of following insulated and stirred 90 minutes.
Additive B: replace ethyl succinate with Succinic acid dimethylester, consumption is 13 grams, the same additive A of its synthetic method.
Example 1: additive A 8ml/l
Piperonylaldehyde 20mg/l
Tetraethylene-pentamine 2g/l
Example 2: additive B 8ml/l
Piperonylaldehyde 20mg/l
Tetraethylene-pentamine 2g/l
Example 3: polyoxyethylene glycol (molecular weight 1540) 2g/l
Piperonylaldehyde 20mg/l
Tetraethylene-pentamine 2g/l
Example 4, polyoxyethylene glycol (molecular weight 1540) 2g/l
Piperonylaldehyde 20mg/l
Many second polyamines 2g/l
Example 5, polyoxyethylene glycol (molecular weight 1540) 2g/l
Aubepine 20mg/l
Tetraethylene-pentamine 2g/l
Example 6: peregal 2g/l
Piperonylaldehyde 20mg/l
Tetraethylene-pentamine 2g/l
The Hull Cell test piece effect of above-mentioned 6 examples is seen accompanying drawing.By these Hull Cell test pieces as can be seen:
Example 1 light district is at 0.5～10A/dm
2
Example 2 light districts are at 0.8～8A/dm
2
Example 3 lights and half light district are at 1～10A/dm
2
Example 4 lights and half light district are at 0.8～10A/dm
2
Example 5 lights and half light district are at 0.8～10A/dm
2
Example 6 lights and half light district are at 0.2～7A/dm
2
In above-mentioned example, if do not add additive 1, almost do not go out bright coating, just produce or enlarged lighted region just because of its adding, in the current density range of broad, obtained the tin-zinc alloy electrodeposits of light or half light.In addition, in electroplating, reality finds also that the adding of additive 1 has reduced fringing effect.
