Abstract

The invention belongs to the field of metal surface cleaning, and particularly discloses an electroplating activating agent and a preparation method of the electroplating activating agent. The electroplating activating agent comprises, by weight, 10-80 parts of organic acid, 0.5-5 parts of inorganic acid, 0.1-2 parts of surfactants, 0.1-2 parts of additives, 0.1-2 parts of polyamide substances and0.2-1 part of ether substance. The combination of the organic acid and the inorganic acid can effectively remove an oxide film of a plated part. The polyamide substances including polyamide ether, polyamide sodium and polyamide potassium contain amido bonds, the amido bonds are functional groups with electronegativity and have the good hydrophilicity, and stains on the surface of the plated partcan be effectively removed. The ether substances including polyether polyol, halogenated ether and polyamide ether contain ether bonds, and the ether bonds are polar groups, and the adhesion effect isfacilitated.

Description

technical field [0001] The invention belongs to the field of metal surface cleaning, in particular to an electroplating activator 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] Electroplating activator generally refers to the process of eroding the plated parts by acid or alkali solution to dissolve the oxide film on the surface to expose the active metal interface, so as to ensure the bonding force between the electroplating layer and the substrate. [0004] In the prior art, the electroplating acti...
