Embodiment 1

[0024] A kind of preparation method of antimony electroplating solution is as follows:

[0025] Add 20 g of boric acid, 10 g of sodium hypophosphite, and 10 g of a complexing agent (sodium acetate) into deionized water, stir and dissolve to form a mixed solution, adjust the pH to 1.0 with HCl, add 1 g of potassium antimony tartrate to the mixed solution, and stir to dissolve. Then add the remaining amount of deionized water to a total volume of 1 L, adjust the pH to 0.5, and obtain an antimony electroplating solution.

Embodiment 2

[0027] A kind of preparation method of antimony electroplating solution is as follows:

[0028] Add boric acid 80g, sodium hypophosphite 80g, complexing agent (ammonia acetate) 80g to deionized water, stir and dissolve to make a mixed solution, adjust pH=3.0 with HCl, add antimony potassium tartrate 10g to the mixed solution, stir to dissolve, Then add the remaining amount of deionized water to a total volume of 1 L, adjust the pH to 3.0, and obtain an antimony electroplating solution.

Embodiment 3

[0030] A kind of preparation method of antimony electroplating solution is as follows:

[0031] Add 40 g of boric acid, 40 g of sodium hypophosphite, and 60 g of complexing agent (sodium acetate) to deionized water, stir and dissolve to make a mixed solution, adjust pH=2.0 with HCl, add 4 g of antimony potassium tartrate to the mixed solution, stir and dissolve, Then add the remaining amount of deionized water to a total volume of 1 L, adjust the pH to 1.5, and obtain an antimony electroplating solution.

Abstract

The invention relates to the technical field of electroplating, in particular to an antimony electroplating solution and a preparation method thereof. The antimony electroplating solution comprises 20to 80g / L of boric acid, 10 to 80g / L of sodium hypophosphite, 10 to 60g / L of complexing agent, an appropriate amount of water and 1 to 10g / L of antimony salt. An antimony plating layer is obtained byutilizing an electroplating method, and has attractive color and luster and high specific capacity; and the antimony electroplating solution has good stability.

Description

technical field [0001] The invention relates to the technical field of electroplating, in particular to an antimony electroplating solution and a preparation method thereof. Background technique [0002] Electroplating has the advantages of simple process, low cost, easy operation and large-scale application, and is widely used in daily life. Electroplating single metal is far from meeting the modern demand for functional materials. Therefore, with the rapid development of electroplating multi-element alloys in recent years, there are various types and excellent material properties, and they have been widely used in the magnetic industry and energy fields. [0003] The theoretical capacity of antimony is as high as 660mA·h / g, much higher than the current commercial carbon materials, and it is a promising energy material. At present, the methods for preparing antimony alloys mainly include vacuum evaporation method and sputtering deposition method, but these preparation met...
