Problems solved by technology

[0002] Many acidic galvanizing brighteners have been developed in China. With different brighteners, there is no big difference in the brightness of the coating. In order to improve the brightness of the galvanized layer and the quality of the coating, a bright acid galvanizing brightener has been developed. The brightener is mainly It is composed of main brightener, carrier brightener and auxiliary brightener. At present, some brighteners used in China have good coating brightness, but are prone to brittleness, and some coatings are relatively soft, but the brightness is not good.

Embodiment 1

[0028] A potassium chloride type galvanized electroplating solution, the solvent is water, and its components are:

[0029] Zinc chloride 70g / L

[0030] Potassium chloride 200g / L

[0031] Boric acid 35g / L

[0032] Softener 8mL / L

[0033] Brightener 0.3mL / L

[0034] The appropriate amount of regulator is 5mL / L.

[0035] Wherein, described softening agent comprises benzylidene acetone, sodium benzoate and nicotinic acid;

[0036] Described brightener comprises o-chlorobenzaldehyde;

[0037] Described adjustment agent comprises boric acid, methyl alcohol, sodium benzoate.

Embodiment 2

[0039] According to the composition described in embodiment 1, carry out the preparation of electroplating solution:

[0040] (1) Clean the galvanizing tank and add 1 / 3 of water;

[0041] (2) The potassium chloride of formula quantity is added into water and goes, until potassium chloride is all dissolved, then the zinc chloride and boric acid of formula quantity are dissolved successively;

[0042] (3) After stirring evenly, cool to room temperature and take the plating solution for analysis. If the concentration is not within the specified range, it must be adjusted before adding additives;

[0043] (4) Turn on the filter to start the cycle, and electrolytically treat the plating solution with a small current density of 0.1-0.15ASD for 4-12 hours, until the color of the coating in the low current density area changes from black to light gray, add the required amount of softener, bright Agents and modifiers, dissolved, stirred evenly and can be.

[0044] The electroplating ...

Abstract

Belonging to the field of plating solutions, the invention relates to a potassium chloride-type galvanizing plating solution and its preparation method. With water as the solvent, the plating solution of the invention is composed of the following components: zinc chloride at a concentration of 50-80g / L, potassium chloride at a concentration of 180-280g / L, boric acid at a concentration of 30-40g / L, a softening agent at a concentration of 6-10mL / L, a brightener at a concentration of 0.1-0.4mL / L, and a proper amount of a conditioning agent. The plating solution prepared by the method of the invention is characterized by fast lightening speed, good leveling, high temperature resistance, and fewer decomposition products.
