Background

Gold is known to be a precious metal. Small unit volume, corrosion resistance, pollution resistance, easy storage, and both currency and collection values. The possession amount can be regarded as the representation of the property, identity and status of people. With the increasing wealth of human society, people simply possess gold and ordinary gold products and cannot meet the needs of people. Therefore, there is a need to further increase the added value of gold, and to make gold into various handicraft products, which are more noble and elegant, and more convenient for display and collection. Therefore, some people have printed patterns on gold boxes for storage, but the gold boxes have poor mechanical strength, are brittle and not resistant to folding, and the printed patterns are discolored due to light pollution and air oxidation, so that the gold boxes cannot be stored for a long time. With the increasing wealth of human society, people's needs cannot be met by simply having gold and common gold products, and gold printing and printing products with rich cultural and cultural contents are favored by people. For example, publication numbers are: the invention patent of CN 106926629A discloses a method for preparing metal gold painting by gold film, which adopts sputtering coating method, argon with purity of 99.99% is introduced into vacuum chamber of coating instrument, and the prepared gold layer, surface smoothness and firm strength need further optimization because argon is introduced singly.

Detailed Description

In order to better illustrate the present invention, the technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the embodiments of the present invention.

The gold nano imaging method provided by the invention comprises the following steps:

(1) preparing a pure gold target with the purity of 99.99 percent by using a vacuum melting method;

(2) placing the pure gold target prepared in the step (1) on a target position in a vacuum chamber of a GVC-1000 ion sputtering instrument, and vacuumizing the vacuum chamber of the GVC-1000 ion sputtering instrument with the vacuum degree of 10^-6torr；

(3) Introducing argon gas into the vacuumized vacuum chamberThe mixed gas of helium makes the vacuum degree in the vacuum chamber reach 2 × 10^-3torr as a working gas;

(4) adding 800V high voltage between the pure gold target surface and the wall of a vacuum chamber of the GVC-1000 ion sputtering instrument, and carrying out ion beam impact on the pure gold target; and after the pure gold target surface is impacted by the ion beam, gold atoms escape from the pure gold target and are deposited on the surface of the photographic paper to prepare the gold phase paper layer.

In one embodiment of the present invention, the method further comprises the following steps

(5) Mixing the ink and the metal adhesion agent according to the proportion of 1:0.03 or mixing the ink and the plasticizer according to the proportion of 1:0.05 to prepare a mixed solution;

(6) and (5) printing the yellow metal phase paper layer by using the mixed liquid prepared in the step (5).

In the invention, the type of the metal adhesion agent is FAD-120.

In the invention, the plasticizer is RQT-P-1.

The gold nano imaging method adopts a sputtering coating method, and the sputtering principle is that mixed gas of argon and helium is introduced into a high vacuum chamber of a GVC-1000 ion sputtering instrument, after high voltage is introduced, argon molecules are ionized under the action of an external electromagnetic field to form positive ions and electrons, glow discharge is carried out, and the charged particles are bound near a target surface under the action of the external electromagnetic field to form a stable plasma region. Because a negative voltage of 800V is applied on the gold target, positive ions in the plasma impact the pure gold target at a high speed of 6 kilometers per second under the action of an electric field, so that gold atoms on the surface of the pure gold target are impacted to escape from the surface of the metal solid. These escaping gold atoms can be deposited on the surface of the photographic paper facing it, and after a certain thickness, a yellow phase paper layer is formed. The gold particle layer of the gold phase paper layer manufactured by the process is formed by stacking and arranging gold atoms with high kinetic energy, so that the structure of the gold particle layer is compact, the appearance is smooth, uniform and bright, the firmness is high, the color is good (more than 99.9 percent), and patterns can be directly printed on the gold particle layer.

According to the invention, the mixed gas of argon and helium is introduced, and helium is inactive relative to argon, so that after argon molecules are ionized to form positive ions and electrons, helium cannot be ionized, helium not only has a good bunching effect on plasma gas flow, but also has an obvious bunching effect on gold particle beam flow, so that the prepared gold phase paper layer has a flat, uniform and bright appearance and strong firmness.

To further illustrate the gold nano-imaging method of the present invention, the following detailed description of the gold nano-imaging method provided by the present invention is provided in conjunction with specific implementations, but they should not be construed as limiting the scope of the present invention.
