Embodiment 1

[0019] Embodiment 1: a kind of vacuum coating antiquated copper production process is illustrated as follows with stainless steel products as example:

[0020] (1) Pretreatment of the surface of stainless steel products: use absolute ethanol and calcium carbonate nano powder to clean the surface of stainless steel products, then bake at a constant temperature of 200-230°C for 90 minutes, then take out the workpiece and wipe off the surface of the workpiece after cooling calcium carbonate nanopowder.

[0021] (2) Vacuum copper plating: hang the workpiece pretreated in step (1) on the workpiece rack of the vacuum equipment, and evacuate until the vacuum degree is higher than 2×10 -2 After Pa, the workpiece holder rotates at a rate of 3 r / min-6 r / min, adjust the throttle valve to the required position, turn on the argon gas and the arc source with the titanium target installed, and use the high bias voltage to perform ion bombardment cleaning on the surface of the workpiece Aft...

Abstract

The invention relates to a metal surface treatment technology, and particularly relates to a production technology of vacuum coating antique copper. The technology comprises the following steps: carrying out magnetron sputtering on a work-piece of which the substrate surface is cleaned or coating red copper / brass through plating by a multi-arc ion plating method; carrying out chemical agent black coating on the work-piece coated with the red copper / brass, so as to obtain a black surface film; carrying out manual or mechanical drawing treatment on a copper film on the surface of the work-piece; exposing a part of bottom red copper or brass film, so as to form archaistic stripes; and coating the surface of the work-piece with an organic coating or carrying out fingerprint resistant treatment and then baking at 100-150 DEG C for 20-30 minutes, thus finally obtaining the antique copper product of the vacuum coating composite film. By adopting the production technology, the problems of heavy metal ion pollution and high energy and material consumption existing in the traditional antique copper production technology are solved, the surface smoothness of the film and the binding force of the film are improved, production of the high-quality and pollution-free antique copper decorating film product is achieved, and the antique copper and green bronze products have good surface texture and visual effect.

Description

technical field [0001] The invention relates to a metal surface treatment process, in particular to a vacuum coating antique copper production process. Background technique [0002] At present, the production of antique copper and bronze products mostly adopts wet electroplating and chemical coloring methods. These methods will produce heavy metal ion pollution that is seriously harmful to the environment and human body, and consume water, electricity, and a large amount of precious metal resources. The production cost is high and the process is relatively complicated, which is gradually limited in its application; in addition, the surface finish of the antique copper and bronze film produced by wet electroplating and electrochemical coloring methods is poor, and the bonding fastness between the film and the substrate is relatively poor. Low, it can no longer meet the requirements of high-end user groups for more exquisite and reliable antique copper and bronze decorative co...
