Abstract

The invention discloses a composite electroplating brightener. Every liter of an electroplating solution comprises the following raw materials in parts by volume: 7 to 12 mL/L of copolymer of 2,2-dimethyl-1,3-propanediol and 1,2-ethylene glycol, 7 to 12 mL/L of sodium phenyldithiopropane sulfonate, 3 to 6 mL/L of diphenylamine thiourea, 6 to 10 mL/L of triethanolamine, 1.2 to 2.2 mL/L of sodium polydithiodipropane sulfonate and 14-17 mL/L of a nitrogenous heterocyclic compound. The composite electroplating brightener can be suitable for various electroplating processes such as copper plating,zinc plating, copper-zinc alloy plating and the like, has multiple functions, achieves the brightening effect, and also has remarkable improvement effects on the current efficiency, the elongation, the tensile strength and other properties of a plating layer; and the electroplating brightener has a good hole filling effect on the surface of an electroplated (such as electrocoppering or electrogalvanizing) base material, the surface gloss of the plating layer is high, and the brightening effect is good.

Description

technical field [0001] The invention relates to the technical field of additives for electroplating, in particular to a composite 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 grindin...
