Abstract
The invention discloses a chemical coloring method for copper and alloys of copper, which comprises the following steps of: firstly, abrading and polishing the surface of an copper alloy to be colored; and then, activating the surface of the copper alloy to be colored and washing; microetching the surface of the copper alloy to form a light yellow zinc-enriched membrane layer on the surface of the copper alloy; reacting making the zinc-enriched membrane layer on the surface of the copper alloy react with chemical coloring liquid to generate a metallic compound membrane layer of selenium, wherein the color of the metallic compound membrane layer is reddish black, also calledi.e. red bronze color. A zipper made by the method disclosed in the invention has simulated bronze teeth which have even color and strong color fastness.
Description
Technical field
The present invention relates to field of metal surface treatment, in particular last copper-colored a kind of chemical pigmenting method of copper and alloy thereof, the especially chemical tinting method for bronze color of suitable metal slide fastener and related accessory thereof.
Background technology
Bronze color and luster grace, recently be a kind of rather well received a kind of decorative coating, along with improving constantly of people's living standard, people are to paying close attention to more more in the dressing collocation, coppery particularly modelled after an antique is in the application of copper alloy slide fastener industry, makes this new ideas of decorating clothes with slide fastener that new intention element arranged, and this coppery modelled after an antique also becomes a kind of rather popular color and luster simultaneously, and at present copper-colored method also and imperfection on the surface of copper and copper alloy, bring puzzlement to industry.
Summary of the invention
At the deficiencies in the prior art, the invention provides a kind of to copper and alloy thereof under the effect of this chemical pigmenting liquid, form the oxide skin of metallic surface or the method for other compound retes, particularly be used in the production of the metal zip fastener of copper alloy.
The chemical pigmenting method of a kind of copper and alloy thereof is characterized in that: comprise following step:
At first, then remove the greasy dirt on surface to be colored with copper alloy surface polishing, polishing to be colored;
Copper alloy surface activation to be colored back is cleaned, copper alloy surface is carried out microetch handle, make copper alloy surface form the faint yellow rich zinc rete of one deck;
With the rich zinc rete of copper alloy surface and the metallic compound rete of chemical pigmenting liquid reaction generation selenium, color and luster is a reddish black, promptly red bronze color.
