Description

A kind of chemical copper plating solution and chemical plating method
Technical field
The present invention relates to a kind of process of surface treatment, particularly a kind of new chemical copper plating solution and chemical plating method.
Traditional chemical-copper-plating process is a reductive agent with formaldehyde, and EDTA and Seignette salt are separately or the mixed twine mixture, wherein, the formaldehyde that is adopted, environmental pollution is serious, and its smell is awful, have teratogenecity, mutagenicity, carinogenicity.Therefore, to this problem, developed some formaldehydeless chemical copper plating solutions, still, the formaldehydeless chemical copper plating solution of most conventional is because their hyperergy has relatively poor stability, and decomposes very soon when using.Therefore need exploitation to have the formaldehydeless chemical plating fluid of high stability, and use it can accomplish the electroless copper process rapidly.
The object of the invention is to provide a kind of chemical copper plating solution, does not contain formaldehyde in its composition, has improved Working environment, and has possessed advantages of higher stability, is convenient to management and control.
Chemical copper plating solution of the present invention mainly comprises following component:
Figure DEST_PATH_GFW00000036640900011
Wherein, said complexing agent is a Seignette salt.
Another object of the present invention is to provide a kind of chemical plating method, improves Working environment and reduces the pollution to environment with great.
And the chemical plating method that adopts above-mentioned copper plating solution to carry out, its flow process is: plastic plate alligatoring activation → cleaning → electroless copper → cleaning → conductionization processing → cleaning → chemical nickel plating copper-phosphorus alloy.Wherein, said electroless copper step is specially: the plastic plate that will pass through above-mentioned pre-treatment soaks to place with sulfuric acid and strong aqua the pH value is modulated to the above-mentioned chemical copper plating solution of 10-13, and its working temperature is 20-70 ℃, and the copper facing time is 5-20 minute.
Wherein, described cleaning way can carry out through ultrasonic cleaning or water-washing method.
And said conduction treatment step is the copper-plated plastic plate of process is soaked in the acidic solution, with
Show conductive layer.
The alloy rete that said chemical nickel plating copper-phosphorus alloy step is generated also can make the resistance on this plastic plate top layer and sticking power can reach industrial standards in the etch-proof while.
Thus,, avoided adopting the environmental pollution that formaldehyde brought because of environmental-protecting chemical copper plating solution of the present invention adopts sodium hypophosphite as reductive agent, and adopt Seignette salt be complexing agent to reduce cost, this formulation stability is higher in addition, is easy to management and control; And at aspect of performance, the salt mist experiment that the rete of this method gained can be through 8 hours, and its resistance and sticking power can both reach industrial standards.
