Abstract
The invention relates to preparation of a general brightener for potassium salt zinc plating and sulfate zinc plating. C6H5COONa, C10H10O, AESA, an NNO dispersing agent, an OP emulsifying agent, C6H5NO2 and other substances are dissolved, and mixed uniformly according to a certain ratio. The general brightener can be generally used for potassium salt zinc plating and sulfate zinc plating and brings great convenience to management and production. The brightener can obviously improve the brightness, the leveling property and density of a plating layer, and the requirement on total-area brightness of a test piece can be met in a 2A Hull cell test.
Description
Technical field
The present invention relates to a kind of preparation of sylvite galvanized, the universal bright agent of sulfate zinc plating, relate to electroplating additive (brightening agent) field.
Background technology
Zinc coating has good anti-corrosion capability, is the good corrosion coating of metal.In the industrial widespread use of arriving, account for and electroplate 50%～80% of total amount at present.It is zinc-plated etc. to mainly contain sylvite galvanized, sulfate zinc plating, cyaniding.There is environmental pollution problems in zincincation and cyaniding is zinc-plated etc., thus in zincincation based on sylvite galvanized and sulfate zinc plating.
Wherein, sulfate zinc plating is mainly used in the plating of wire rod, band.Current density is big when being characterized in electroplating, and electroplating time is short.But the dispersive ability of sulfate zinc plating plating bath is relatively poor, and the compactness of its coating, leveling property are relatively poor.Sylvite galvanized mainly carry out ornamental zinc-plated.Sylvite galvanized tank liquor good conductivity, bath voltage is lower during plating, and current density is less.The dispersive ability and the covering power of plating bath are better, and the bath stability height, are widely used at present.
Universal bright agent can be used for the plating of different process, so not only can improve light, leveling property, the density of coating, and is convenient to management aborning and safeguards handled easily.The exploitation of universal bright agent has very big practicality.
Summary of the invention
The present invention is a kind of sylvite galvanized, universal bright agent of sulfate zinc plating, and it can be common to sylvite galvanized, sulfate zinc plating, and can significantly improve light, leveling property and the density of coating.

A kind of sylvite galvanized, universal bright agent of sulfate zinc plating of gained of the present invention is brown liquid.
Description of test
The present invention increases the content of brightening agent successively by carrying out sylvite galvanized experiment, sulfate zinc plating experiment, and observes the coating luminance brightness.Find in the sylvite galvanized experiment that the coating that brightening agent obtains is light, smooth the most in 16～28mL/L scope; In the sulfate zinc plating experiment, the coating that brightening agent obtains in 24～32mL/L scope is light, smooth the most.When brightening agent during at proper range, plating under differing temps is found in the time of 20 ℃～50 ℃, the coating the best that obtains in two kinds of zinc-plated experiments.
Embodiment
The concrete preparation process of present embodiment is as follows:
1. sylvite galvanized Hull groove (250ml) experiment

B. the 2ml brightening agent is added the Repone K galvanizing solution while stirring, make its thorough mixing even.
C. adjust the plating bath pH value once more, make it within processing range.
D. controlled temperature is electroplated when 30 ℃ of left and right sides, observes quality of coating behind the 8min.
E. increase the consumption (at every turn increasing 1ml) of brightening agent successively, send out mist to coating.
F. compare each model quality of coating, draw the brightening agent optimum range.
G. in sylvite galvanized groove, add an amount of brightening agent, adjust pH value to processing range.
H. since 10 ℃, change temperature, carry out successively zinc-plated, fuzzy to coating.
I. compare each model quality of coating, draw best temperature range.
2. sulfate zinc plating Hull groove (250ml) experiment
A. prepare general sulfate zinc plating solution, and adjust pH value.
B. the 2ml brightening agent is added sulfate zinc plating solution while stirring, make its thorough mixing even.
C. adjust the plating bath pH value once more, make it within processing range.
D. controlled temperature is electroplated when 30 ℃ of left and right sides, observes quality of coating behind the 8min.
E. increase the consumption (at every turn increasing 1ml) of brightening agent successively, send out mist to coating.
F. compare each model quality of coating, draw the brightening agent optimum range.
G. in the sulfate zinc plating groove, add an amount of brightening agent, adjust pH value to processing range.
H. since 10 ℃, change temperature, carry out successively zinc-plated, fuzzy to coating.
I. compare each model quality of coating, draw best temperature range.
