Electroplating liquid for electroplating treatment

Abstract

The invention discloses an electroplating liquid for an electroplating treatment. The electroplating liquid is prepared from the following raw material components in parts: 20-25 parts of nickel oxide, 15-20 parts of zinc sulphate, 10-12 parts of aluminium sulphate, 13-15 parts of stannous sulphate, 10-12 parts of manganese sulphate, 3-5 parts of 1,4-bis(phenylacetenyl) benzene, 3-4 parts of dipolyphenyl propargyl ether, 2-3 parts of sodium benzoate, 10-20 parts of oxalic acid, 8-10 parts of potassium fluoborate, 6-8 parts of potassium fluotitanate, 5-6 parts of hydrofluoric acid, 5-8 parts of sodium fluosilicate, 3-5 parts of lead acetate, 10-15 parts of cobalt acetate, 10-12 parts of zinc acetate, 10-15 parts of ethylene glycol monomethyl ether, 3-5 parts of triethylene glycol, 2-4 parts of sodium tripolyphosphate, 3-5 parts of sodium hexametaphosphate, 3-5 parts of sodium pyrophosphate and 8-10 parts of silicone oil. The electroplating liquid for the electroplating treatment is good in corrosion resistance and wear resistance, capable of effectively preventing copper atoms from diffusing to an electrolyte during a use process and reducing waste, fast in precipitation speed, wide in current density range, low in electric energy consumption, good in electroplating quality, and capable of prolonging the service lives of metal copper wires.

Description

technical field [0001] The present invention relates to the technical field of electroplating solutions, in particular to an electroplating solution for electroplating treatment. 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. Grinding, electrical conductivity, reflective and enhancing aesthetics and other functions. [0003] At present, when silver plating is carried out, although the silver layer has strong corrosion resistance, the surface of silver-plated copper wire is easy to interact with sulfides and halides in the air when exposed to the air for a long time, causing overall discoloration of the surface. , not only destroys the appearance, but also increases the contact resistance and deteriorates the brazing performance. The essence of the discoloration of the silver-plated layer is surface ionization. If the purity of the silver-plat...
