Description
Technical field
The invention belongs to corrosion inhibiter class, particularly belong to the metal inhibitor class of gold, silver, copper and mickel, be used for protecting gold, silver,
Copper and mickel, prevents variable color and is corroded.
Background technology
In most of electronic products protection against chemical product formula, metal anti-discoloration post-treatment agent is widely used, its purpose
Being to prevent metal oxidized, variable color and corrosion in using environment, particularly in electronic product, oxidation stain itself also can be made
Becoming contact resistance to increase, solderable hydraulic performance decline, product reduces service life.In electronic product, gold-plated, silver-plated, copper facing, plating
Nickel dam respectively has specific function, have good electric conductivity, heat conductivity, solderability, stability and with matrix reliable adhesion,
Nickel plating product is applied extremely wide in hardware appliance, and it is poor that prior art exists antiseptic property, the shortcoming that the salt spray test time is short.
Owing to gold, silver are expensive, during plating, major part only carries out flash, and coating is very thin, and parent metal is not completely covered, and leaves sky
Gap, causes corrosion resistance inadequate, and in functional and ornamental needs, copper facing, nickel plating are also widely used, particularly electronics
Product need silver-plated after some nickel plating, it is therefore an objective to the oxidized rear solderability of nickel coating reduces, and needs anti-oxidation to improve it
Shortcoming.Copper plate due to ingress of air will oxidation stain, cause degraded appearance, sheet resistance to increase, it is also desirable to had is anti-
Oxidation processes.And the production of above-mentioned electronic devices and components, transport, install and use during, with the H in environment2S、SO2、CO2、
NOxWhen contacting Deng gas, even when being irradiated by ultraviolet light, the most easily generate corresponding corrosion product at coating surface so that it is
Variable color is turned black, and so can greatly destroy the original performance of coating.
Use chemical passivation, electrolytic passivation, coating solvent-borne type protective agent can improve coating to some extent and be corroded
The phenomenon of variable color.But, chemical passivation method easily causes Cr6+Pollute；Electrolytic passivation method has Cr equally6+The problem polluted；
CN101353800A patent proposes to use saturated linear mercaptan to be used on silver Anti-tarnishing as main component, but there is also sulfuration examination
The time of testing falls short of, the shortcoming of non-refractory.For problem above, the present inventor is through development test, it is proposed that use long-chain
The sulfydryl benzene and its derivative of alkyl, as gold, silver, copper, the main component of nickel anti-discoloration after treating agent, through actually used, is preapred for an unfavorable turn of events
Color, corrosion-resistant, resistance to elevated temperatures is notable.
Summary of the invention
The present invention is directed to the deficiency that above-mentioned prior art exists, it is proposed that one is used for protecting gold, silver, copper and mickel, prevents
Oxidized, variable color and corrosion, and preparation method is relatively easy, production process is pollution-free, the post processing protection that properties of product are stable
Agent.
The present invention solves technical problem and is adopted the technical scheme that, a kind of for gold, silver, the metal post processing of copper and mickel
Protective agent, comprises selected from the sulfydryl benzene and its derivative with chain alkyl, and containing can effectively dissolve selected compounds extremely
Few a kind of solvent or surfactant, described surfactant is both sexes, nonionic or anion surfactant.
Preferred as one, the described sulfydryl benzene and its derivative with chain alkyl, wherein chain alkyl is in sulfydryl
The meta of benzene or ortho position or para-position.
Preferred as one, the described sulfydryl benzene and its derivative with chain alkyl is preferably as follows structure:
,,
