DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of dyeing and coloring a member to be colored for semi-precious stones and precious stones for decorative members, and more particularly to a method for coloring a plurality of colors while dyeing them. And the like.

[0002]

2. Description of the Related Art Agate can be colored because chemicals penetrate into a portion of impurities (commonly called proteins) other than quartz which is a latent crystal. Usually, white agate is colored by coloring a plate obtained by cutting a rough stone to an appropriate thickness of about 3 mm to 10 mm by the following method.

[0003] A case where one color of red is colored as described above will be described. As a first example, ferric nitrate (Fe (NO
₃ ) ₃ ) Soak in an aqueous solution for about 20 to 50 days, wash with water, bake it in an electric furnace at a temperature of about 250 ° C. to about 300 ° C. for about 2 to 3 days, and slowly take it out for about 1 day. The part where the chemical has penetrated is colored red (red). In this case, the color is good, but there are few colored portions. As a second example, after immersion in an aqueous ferrous chloride (FeCl ₂ ) solution for about 20 to 50 days, washing with water and immersion in an aqueous sodium nitrate solution (Na (NO ₃ ) ₄ ) for about 20 to 50 days, Rinse and bake as in an electric furnace. Although the method in this case is the mainstream, there are many colored portions but the color tends to be somewhat dark.

[0004] Next, when a green color is applied, the glass is immersed in an aqueous solution of chromic anhydride (CrO ₃ ) for 6 to 10 days, washed with water, and treated with 70% ammonia acetate (CH ₃ COONH ₄ ) solution.
Immersed in a mixed solution of about 30% glacial acetic acid for about 20 to 50 days, washed with water, baked in an electric furnace at about 220 ° C. to 280 ° C. for about 2 to 3 days, and slowly baked for about 1 day. When the pot is cooled down, it is colored chrome oxide dark green. To change the color to light green, use potassium chromate (K ₂ CrO ₄ ) instead of chromic anhydride.

[0005] In the case of coloring black the agate, 20 days sugar solution or furfural solution _{(C 5 H 4 O 2)} ~5
After soaking for about 0 days and washing with water, 250 ° C-300
If it is baked for 2 to 3 days at about ℃ and slowly taken out for 1 day, it is colored carbonized black.

[0006] Further, in order to color blue agate, it is immersed in an aqueous solution of cobalt chloride (COCl ₂ ) for about 20 to 50 days, washed with water and then heated in an electric furnace at a temperature of about 250 to 300.
It is colored blue (light color) when it is slowly cooked out for about one day and then taken out for about 3 days. To darken, immerse in strong ammonia solution for about 5 to 10 days before quenching, wash with water and bake in the same manner. If the temperature is low, the color may fade.

[0007] In addition, when the agate is colored yellow, it is immersed in an aqueous solution of potassium chromate for 20 to 50 days, washed with water and heated at a temperature of about 250 ° C to 300 ° C for 2 to 3 days, and baked for 1 day. When the pot is slowly cooled, it is colored yellow and sage. In this case, there are few yellow parts. In this way, natural agate is red, which is red, black, blue, green, yellow, etc., according to this coloring method, while iron oxide soaks into white agate over time and becomes red. It was possible to color one color as follows.

Conventionally, when making a so-called stone cameo, half of the thickness of a plate obtained by cutting a rough stone into an appropriate thickness of about 3 mm to 4 mm is colored with one color such as red, green, black, or blue. It is made by engraving a female figure by hand engraving or ultrasonic processing on the white part of the surface plate.

[0009]

However, according to the conventional agate coloring method, only one color can be colored for one agate, but if it is to be multicolored, it is necessary to overlap the colors. Must avoid
For example, in the case of coloring 3 mm to 10 mm plate agate, it takes about 20 to 50 days to color one color, and it takes about 40 to 100 days to color two colors. Not only that, it was impossible at all to sharply separate and color. The present invention has been developed as a result of diligent research to solve the above-mentioned conventional problems, and has been developed by dyeing, for example, to enable a vivid coloring while dyeing a plurality of colors such as agate. It is intended to provide a coloring method.

[0010]

In order to achieve the above-mentioned object, the present invention uses a semi-finished product which is not polished to become a product as a material to be colored for a semi-precious stone or precious stone decorative member such as agate. The time to color one color is about 10 to 20 days. To avoid duplication of colors, paint the paint that does not penetrate the non-colored parts, drop the paint after coloring, and remove the paint for the next color. The other part is painted with the paint except the part described above, and the next color is colored. In this case, the coloration using the semi-finished product is because the semi-finished product does not show the uncolored portion inside even if only the surface is colored, so that the coloring time is shortened as a result. Because it will be.

More specifically, in a method of dyeing and coloring a semi-precious stone or precious stone, such as agate, for a decorative member, a non-permeable coating layer is provided on the remaining region other than the colored region of the colored object. After the application, the colored area is appropriately colored, then the non-permeable coating layer is removed, and then the non-permeable coating layer is applied to the remaining area of the colored area to be colored differently from the above-mentioned coloring. After that, the coloring region is colored, and thereafter, the step of removing the non-permeable coating layer is repeated one or more times, thereby coloring the object to be colored by coloring, such as agate, etc. It is.

[0012] The non-permeable coating layer comprises 10% ethyl acetate.
~ 20%, toluene 10% ~ 20%, xylene 5% ~ 1
A vinyl chloride resin coating composed of 0% of main components is used.

The above-mentioned object to be colored is formed by cutting natural agate to form a thin plate, arbitrarily selecting a natural striped pattern formed at the time of producing the agate of the thin plate, and coloring the object to be colored. Things. The other coloring object is a stone cameo obtained by cutting a natural agate to form a thin plate, and engraving a female image on the thin plate by hand engraving or ultrasonic processing.

According to another invention, a vacuum impregnating device is mounted on one of the tanks and a compressor is mounted on the other of the tanks, and a container containing a chemical solution for coloring and agate to be colored is placed in the tank. By removing the air in the tank with a vacuum and removing the moisture inside the agate, air, etc., maintaining a vacuum state in which the solution permeates for a predetermined time, switching to the compressor and supplying air pressure for a predetermined time,
This is a dyeing / coloring method such as a caulking or the like for allowing the dyeing area to be clearly colored by vertically penetrating the solution into the coloring area.

[0015]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the method for dyeing and coloring agate and the like in the present invention will be described below in detail with reference to the drawings. First Embodiment First, an agate 1 for a landscape image or the like will be described with reference to FIG. There is agate called fancy agate in natural agate. In this agate, various stripes are formed by heat, pressure, etc. at the time of generation. After that, impurities such as iron oxide penetrate over a long period of time and are colored. This is 3m
When cut into a suitable board of about m to 10 mm, at first glance there are places that look like buildings, mountains, valleys, etc. or other patterns. This part is 15 × 20mm to 35 × 45
It is processed into a size of about mm to color solid areas other than patterns. In this case, the patterned agate 1 uses a semi-finished product that has not been turned into a finished product. In this case, the coloration using the semi-finished product is because the semi-finished product does not show the uncolored portion inside even if only the surface is colored, so that the coloring time is shortened as a result. Because it will be.

In FIG. 1, a forest of a pattern mask 1 and a plain 2
And coat all other parts with paint that is not soaked in chemicals. The non-permeable coating layer, which is a coating material, uses a vinyl chloride resin coating material composed mainly of 10% to 20% of ethyl acetate, 10% to 20% of toluene, and 5% to 10% of xylene. In this state, the agate 1 is immersed in an aqueous solution of chromic anhydride or potassium chromate for about 5 days, washed with water, and then dipped in a 70% ammonia acetate to 30% glacial acetic acid solution for 5 days.
After soaking for about 10 days, washing with water, the paint is dropped with a thinner or the like, and lightly baked in an electric furnace at a temperature of about 100 ° C to 120 ° C.

After that, the part which becomes empty 3 is left, and the remaining part is covered with a paint, soaked in an aqueous solution of cobalt chloride for about 20 days, washed with water, and the paint is dropped with a thinner or the like.
Bake at about 0 ° C to 300 ° C for 2 to 3 days, and slowly slow it down for about 1 day before removing it from the pot. Natural patterns are mostly iron oxide, so if they are baked at the same time, they will become red mountains 4, forests and plains 2 will be green, and sky 3 will be blue, and a beautiful landscape painting will be completed.

Second Embodiment A method of coloring a multicolored stone cameo will be described with reference to FIGS. In this example, the plain agate 5 before coloring is
First, the female image 6 is multicolored by hand engraving or ultrasonic processing. First, the remaining portion of the flower 7 of the sculptured female image 6 is left, and the other portion is painted and hardened with a paint (vinyl chloride resin paint). After that, heat processing at about 100 ° C. to 120 ° C. and immersion in an aqueous ferrous chloride solution for about 10 to 20 days,
After washing, soak in sodium nitrate aqueous solution for 10 days to 2 days.
0 days later, it is washed with water and heat-treated in an electric furnace at a temperature of about 100 ° C to 150 ° C.

Next, the paint is washed off with a thinner or the like, and then the paint is applied to the entire female image 6 (including flowers) for 10 minutes.
Heat processing at about 0 ° C. to 120 ° C., immersion in an aqueous solution of chromic anhydride or an aqueous solution of potassium chromate for about 3 to 5 days, washing with water, and adding 5% to a mixture of 70% sodium acetate solution + 30% glacial acetic acid. Soak for about 10 to 10 days, wash out and bake in an electric furnace at a temperature of about 230 ° C to about 280 ° C for about 2 to 3 days, and slow down for about 1 day. Thus, a stone cameo 9 having a red flower 7 on the white female figure 6 and a green color 8 on the outside and the back is completed.

Third Embodiment FIG. 4 is an explanatory view showing an example of a dyeing method according to the present invention. In this case, a solution as a coloring agent penetrates by a capillary phenomenon, but spreads not only vertically but also horizontally. The boundaries are blurred. To avoid this, vacuum impregnation device (vacuum pump) 10
Coloring is performed using the pressure of the compressor 11.

As shown in FIG. 4, a vacuum impregnation device 10 is mounted on one side of a tank 12 and a compressor 11 (for example, 10 atm) is mounted on another side. The coloring chemical solution 13 and the agate 14 to be colored are put in the same container 15 in the tank 12, and after sealing, the air in the tank 12 is first evacuated by the vacuum impregnating device 10 to make a vacuum state. After the water, air and the like are removed and the vacuum state where the solution permeates there is maintained for 1 to 2 hours, then the compressor 11
And air pressure of, for example, about 10 atmospheres for 1 hour to
Take 2 hours. In this way, the solution permeates perpendicularly into the agate 14 and a clear smearing color can be obtained. In addition, the dyeing and coloring method of the present invention can dye and paint a picture or pattern like white agate and has various application ranges.

[0022]

As is apparent from the above description, the present invention applies an impermeable coating layer to the remaining region other than the colored region of the object to be colored, and then appropriately colors the colored region.
The non-permeable coating layer is removed, and then the remaining area of the colored area to be colored differently from the above-mentioned coloring is applied with the non-permeable coating layer, and then the colored area is colored. Since the coloring of the object to be colored is performed by repeating the step of removing the permeable coating layer one or more times, it is possible to reliably color while coloring a plurality of colors such as agate. Multicoloring makes it colorful and has the effect of beautifying accessories.

Also, some natural agates have various patterns, and by using the patterns to color the space, it can be made into a landscape pattern, etc., and the commercial value can be significantly increased. By coloring the surface of the white agate cameo, it is possible to obtain a splendid and gorgeous picture cameo. Further, by coloring using a vacuum impregnating device and compressor pressure, the coloring liquid has a useful effect such that the coloring liquid penetrates vertically into a thick portion such as agate, and a clear dyeing state can be obtained.
