Abstract

The invention discloses a stable electroplating solution which comprises an electroplating solution body; and the electroplating solution body is prepared from the following components: 15 to 30g/L of sodium stannate, 25 to 35g/L of sodium hydrogen phosphate, 40 to 60g/L of sodium nitrite, 25 to 40 g/L of potassium hydroxide, 15 to 25 g/L of potassium cyanide, 30 to 50 g/L of copper sulfate, 10 to 25 g/L of zinc oxide and 10 to 25 g/L of citric acid, and is obtained by adding a mixed solution of sodium stannate, sodium hydrogen phosphate and sodium nitrite into a mixed solution of potassium hydroxide, copper sulfate, potassium cyanide, zinc oxide and citric acid. Therefore, the stability of the electroplating solution can be improved; and as the components are mixed in batches, pre-reactions of the reaction liquids (components) are avoided in advance, and the temperature safety of the electroplating solution is improved.

Description

technical field [0001] The invention relates to the field of electroplating solutions, in particular to a stable electroplating solution. Background technique [0002] Electroplating solution refers to a liquid that can expand the cathodic current density range of the metal, improve the appearance of the coating, and increase the stability of the solution against oxidation. There are countless types of electroplating solutions, and there are more than ten types that have been used in manufacturing experiments. At present, there are four kinds of plating solutions commonly used in production: cyanide galvanizing, zincate galvanizing, chloride galvanizing and sulfate galvanizing. According to the difference of the main salt and other ingredients, many plating solutions have evolved, but they are similar with minor differences. However, the general electroplating solution is made by concentrated mixing, and some components will react in advance during the mixing process, resu...
