Problems solved by technology

[0008] 1. The electroplating brightener needs the help of organic solvents, which are easy to volatilize and difficult to handle, which can easily cause environmental pollution and physical injury to electroplating workers;
[0009] 2. The hole filling effect on the surface of the electroplating (electrogalvanizing) substrate is average, the gloss is not high, and the bright effect is not good;
[0010] 3. The function is single. In addition to achieving the bright effect, it lacks the effect of improving the current efficiency, elongation and tensile strength of the (electro-galvanized) coating, or the effect of the improvement is very small

Abstract

The invention discloses a water-soluble electroplating brightener. The water-soluble electroplating brightening agent comprises the following raw materials of, in parts by weight, 15-25 mL / L of a mainbrightener, 12-20 mL / L of an auxiliary brightener, 1.5-3.5 mL / L of an inhibitor, 9-14 mL / L of a leveling agent and 0.7-1.2 mL / L of other auxiliaries according to the volume fraction of each raw material in each liter of electroplating solution. The water-soluble electroplating brightener is composed of 100% water-soluble raw material, does not need an organic solvent, and can effectively reduce environmental pollution and harm to the body of an electroplating worker; the hole filling effect on the surface of an electroplating (electrogalvanizing) base material is good, the glossiness of a plating layer is high, and the bright effect is excellent; in addition, except for achieving the bright effect, the electric current efficiency, the elongation, the tensile strength and other propertiesof the (electrogalvanizing) coating are not greatly improved.

Description

technical field [0001] The invention relates to the technical field of additives for electroplating, in particular to a water-soluble electroplating brightener and a preparation method thereof. Background technique [0002] Electroplating is the process of plating a thin layer of other metals or alloys on the surface of certain metals using the principle of electrolysis. It is a process of using electrolysis to attach a layer of metal film to the surface of metal or other material parts to prevent metal oxidation ( Such as rust), improve wear resistance, electrical conductivity, reflective properties, corrosion resistance (copper sulfate, etc.) and enhance the appearance. [0003] The main function of the brightener is to remove the oil, oxidized and unoxidized surface impurities staying on the metal surface through the active surface, and to maintain the cleanliness, gloss and color fastness of the outside of the object. The texture of the appearance is affected by the gri...
