Silver plating solution brightener

Abstract

The invention discloses a silver plating solution brightener. The silver plating solution brightener is composed of the following raw materials: 5-8 parts of ethylene glycol butyl ether, 6-9 parts ofmagnesium stearate, 3-5 parts of disodium phosphate dodecahydrate, 5-7 parts of quartz powder, 4-6 parts of sodium lauryl ether sulfate, 3-5 parts of trisodium phosphate, 5-8 parts of isomeric alcoholethoxylates, 5-9 parts of hydroxyethylcellulose, 6-8 parts of naphtha, 5-7 parts of methylparaben, 6-8 parts of ethyl maltol, 3-5 parts of otcamethylcyclotetrasiloxane, 5-7 parts of phosphorus pentoxide, and 5-8 parts of ethylenediaminetetraacetic acid. The silver plating solution brightener has the advantages of bright coating mirror surface, high plating solution stability, hard coating, good anti-discoloration ability of the coating, ideal brightness effect and the like.

Description

technical field [0001] The invention relates to the technical field of brighteners, in particular to a brightener for silver plating electroplating solution. Background technique [0002] At present, silver plating is a kind of precious metal electroplating, because the cost of silver plating is relatively lower than that of gold plating, and it has high conductivity, light reflectivity and chemical stability to organic acids and alkalis, so it is widely used It is used for functional electroplating such as decorative electroplating electronic devices. Due to the rapid development of electronic technology this year, functional silver plating has grown rapidly. However, highly toxic cyanide silver plating is still the mainstream of silver plating industry at home and abroad. With the continuous improvement of people's awareness of environmental protection, it is urgent to develop a mature cyanide-free silver plating process to replace the heavily polluting cyanide silver plat...

Problems solved by technology

[0003] In addition, the current cyanide-free brighteners have defects such as low stability of the plating solution, too brittle coating, poor anti-discoloration ability of the coating, and unsatisfactory brightening effect.
