Description
Technical field
The present invention relates to the zinc alloy surface processing technology field, be specifically related to a kind of zinc alloy surface electroless copper.
Background technology
Zinc alloy is that a kind of domestic reserves are abundant, and the price alloy product lower than copper alloy, has that fusing point is low, physical strength is higher, ductility is better and is easy to cast and the advantage of cut.But zinc alloy is not corrosion-resistant, and surface easy generation oxidation affects is attractive in appearance in environment, and can influence other performances with the etching time prolongation.Therefore, zinc alloy need carry out surfacecti proteon in application process.Generally, at first, on the basis of copper coating, obtain the existing coating that protective effect is arranged again attractive in appearance then through methods such as dyeing, eleetrotinplate, nickel plating in zinc alloy base material electroplating surface layer of copper.In practical application, require various binding force of cladding material strong, coating is evenly and have a certain thickness.
Because the normal Recipe that contains prussiate that adopts of traditional bottom copper facing, technology is brought certain pollution than complicacy and to environment and production.Traditional chemical-copper-plating process is a reductive agent with formaldehyde etc., and EDTA and Seignette salt are separately or the mixed twine mixture, therefore environment and human body are all had great harm.To this problem, developed some formaldehydeless chemical copper plating solutions, still, the formaldehydeless chemical copper plating solution of most conventional will soon decompose during use because their hyperergy has relatively poor stability.In addition, the chemical-copper-plating process of having developed because the pH value of copper plating solution is lower, is prone to cause the zinc alloy corrosion, is not suitable for the copper facing of zinc alloy bottom.
Therefore, need a kind of formaldehydeless chemical copper plating solution and copper-plating technique thereof that is fit to active zinc alloy material of exploitation with high stability, can be rapid, pollution-free, do not have a zinc alloy bottom electroless copper process of carrying out caustically.
Summary of the invention
Technical purpose of the present invention is to provide a kind of chemical copper plating solution of zinc alloy surface; Not containing formaldehyde, acetaldehyde etc. in this chemical copper plating solution has the composition of great harm to environment and human body; And having advantages of higher stability, is a kind of environmental protection of zinc alloy, stable, practical chemical copper plating solution of being used for.
The chemical copper plating solution of zinc alloy surface of the present invention mainly comprises following component:
Wherein, complexing agent includes but not limited to Seignette salt and EDTA Disodium.
A kind of technology of utilizing above-mentioned chemical copper plating solution to carry out the zinc alloy surface electroless copper that the present invention also provides, this technical process is:
(1) zinc alloy is carried out ultrasonic oil removing, hot water wash, cold wash successively, carry out acid-wash activation then and handle, the pickle solution of remained on surface is removed in washing afterwards;
(2) the pH value of the chemical copper plating solution of zinc alloy surface provided by the invention is regulated, making its pH value is 10.5～13.0;
(3) zinc alloy after step (1) is handled is put into the chemical copper plating solution that step (2) obtains and was soaked 3～6 minutes, and washing oven dry then promptly obtains the zinc alloy that Electroless copper finishes.
Compared with prior art; The chemical copper plating solution of zinc alloy surface provided by the invention does not contain formaldehyde, acetaldehyde etc. have great harm to environment and human body composition; Effectively reduced environmental pollution; And this chemical copper plating solution cost is low, have advantages of higher stability, therefore is a kind of environmental protection of zinc alloy, stable, practical chemical copper plating solution of being used for.In addition; Adopt the chemical-copper-plating process of zinc alloy surface provided by the invention to comprise operations such as oil removing, activation, electroless plating; Technology is simple, and environmental protection is easy to realize, has overcome present zinc alloy electroless copper and be difficult to the plating problem; Be a kind of environmental protection, economic, practical chemical-copper-plating process, have a good application prospect.
