Description

A kind of rare earth improves Brush Plating silver plating liquid and preparation technology thereof and using method
Technical field
The present invention relates to technical field of electrochemistry, be specifically related to a kind of rare earth improvement Brush Plating silver plating liquid and preparation technology thereof And using method.
Background technology
DL/T486-2010 standard specifies, disconnecting switch and earthed switch contact surface must be silver-plated, and thickness of coating is not Less than 20 microns, to obtain relatively low contact resistance, thus ensure good electric conductivity, require that silver coating has resistance to simultaneously The performances such as erosion, wear-resisting and fastness.Technique of brush plating utilizes the plated pen (anode) being wrapped with the extraordinary plating solution of jacket dipping to fit in work Part (negative electrode) plated position the formation coating that does relative motion, its maximum feature be deposition velocity be about 10 times of Common platings with On.Some manufacturer uses the method for Silver Brush Plating to repair underproof isolation switch contact silver coating the most at the scene Multiple, so that thickness conformance with standard requirement, and there is no concerned countries standard or industry standard at present and contact silver coating technique is entered Row clear stipulaties.What is more important, although functional silver-plated along with electroplating technology is at electronic devices and components, quasiconductor and instrument instrument Popularization and application in table and fast-developing, but cyanide is silver-plated is still that the most silver-plated main way at present because of its Inherent advantage Footpath.This allows for hypotoxic non-cyanide silver coating correlation technique becomes study hotspot always.Therefore, to without cyanogen Brush Plating silver plating process Carry out furtheing investigate and there is certain realistic meaning.
Non-cyanide silver coating has obtained the extensive concern of people very early, such as: thiosulfate is silver-plated, imino-diacetic ichthyodin The silver plating process such as silver-plated, Nicotinic acid silver plating, potassium ferrocyanide are silver-plated are invented by people.But, compare still with cyaniding plant of silver There is shortcomings: (1) bath stability sex chromosome mosaicism: the silver ion in plating solution can become simple substance, Jin Erying under sunlight irradiates Ringing the concentration of silver ion in plating solution, some complexant also can affect plating solution character, such as fourth two phthalimide facile hydrolysis, etc.；(2) coating Adhesion is poor, and coating is easy to foaming, crackle occurs: owing to silver-plated product is usually copper and copper alloy, due to the normal potential of copper More negative than silver much, when copper and alloy plating piece thereof insert plating solution, i.e. it may happen that displacement reaction before being not powered on, on plating piece surface Forming displacement silver layer, it is poor with the adhesion of plating piece matrix, and also has the cupra matter of part to pollute plating solution simultaneously, generally adopts This problem is solved by methods such as pre-silver-plated, leaching silver or amalgamate.
It is apparent that Brush Plating silver plating process flow process also needs to improve coating performance by plating solution research further, logical Before crossing the plating of specification matrix material, plating posttreatment technique improve plating piece homogeneity, the brush plating time needs further briefly to simplify Application operating.
