Abstract
A chemical colouring method for bronze of copper is a method for forming oxide layer or other compound film on metal surface under the action of chemical colouring liquid. The treated workpiece is first polished, electrochemically polished, the surface oxide layer is then eliminated with dilute sulfuric acid to activate the surface, and the treated workpiece is then set inside prepared chemical coloring liquid. The method comprises the steps of forming a film with a tan or grey color in coloring liquid, and polishing by using a soft filler to ensure that the part protruding is thinner or the natural color of part copper is exposed, so that the part presents different shades, namely the antique copper color is obtained. The painted workpiece may have one organic varnish protecting film coated to raise the painting effect.
Description
Technical field
The present invention is the bronze-colored painted chemical treatment method of metal finishing industry field, particularly a kind of copper.
Background technology
Bronze color and luster grace is a kind of rather well received a kind of decorative coating recently, and along with improving constantly of people's living standard, people are more and more welcome to the making of artwork, and copper particularly modelled after an antique has begun the utilization in building trade.Mould picture as large-scale artistic copper, the copper gate, coppery modelled after an antique fields such as copper window constantly enlarge.Therefore it is extremely important to seek a kind of simple and practical coppery making method modelled after an antique.
Summary of the invention
The present invention is meant copper under the effect of its chemical pigmenting liquid, forms the oxide skin of metallic surface or a kind of method of other compound retes, and it mainly comprises surface preparation, and technologies such as chemical stain and aftertreatment are formed.
Embodiment
With processed workpiece polishing refine earlier polishing, again through electrochemical etching, remove the zone of oxidation on surface then with dilute sulphuric acid, make its surface active, put it into then in the chemical pigmenting liquid that has prepared.
Specific implementation method:
Copper sulfate: 30g/L ammonium chloride: 20g/L sodium-chlor: 20g/L
Zinc chloride: 1g/L acetate (36%): 3-5m1/L
The film that forms brown or ash colour developing in its coloring liquid get final product, uses the wadding polishing then, makes the true qualities of the thinner or exposed portions serve copper of the part of part protrusion, makes the part position present the different tone of the depth like this, promptly obtains copper-colored color and luster.Workpiece after painted can also can improve painted effect at the organic varnish protective membrane of surface-coated one deck.
Claims (2)
1. the present invention utilizes a kind of method of chemical oxidation treatment to make copper become copper-colored method.
2. the main component of its chemistry preparation liquid is: copper sulfate, ammonium chloride, sodium-chlor, zinc chloride and acetate.
