Abstract

PURPOSE:To provide an artificial opal with brilliance similar to that of a natural one and can be freely made in a size and a shape by hardening a multi- layered polymer with optical interference phenomenon after it is embedded in a liquid resin. CONSTITUTION:Liquid epoxy resin into which a hardener and a blue coloring agent are mixed is poured into a hole 2 of a rubber mold 1. A multi-layered polymer film piece 3 cut out in a jewel shape plane cross section fittable to the hole 2 from the wrinkled and yellowed multi-layered polymer film is embedded in the liquid epoxy resin 4. The resin is taken out from the rubber mold after hardening. When the multi- -layered polymer film piece 3 is surrounded by the liquid resin 4, its brilliance is increased to a far more excellent level and cannot be discriminated from that of a natural one. Thus, greenish brilliance of a black opal can be obtained. An artificial fire opal can be obtained when a yellowish multiple polymer film and red colored liquid resin are used.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing artificial opal and the artificial opal.

[0002]

2. Description of the Related Art Conventionally, except for opal, all artificial mimicry stones existed, but only opal did not exist. It is artificially transparent and colorless, yellow or blue,
It may be because it was extremely difficult to form an array of molecules that optically separate, interfere, and reflect the spectrum of light, which is the mechanism of opal shine, sometimes in a reddish rough. It has been a long time since a piece of gold or silver plate was embedded in a synthetic resin and molded to reflect light. Recently, many small pieces of phonography film whose shapes and colors change depending on the viewing angle have been embedded to reflect and change the color to give off brilliance. It is a reflected light ray from a board similar to that and the characteristic of the reflected light ray is that it is glittering, the light itself is intense, and it is far from the shine of opal that creates that soft atmosphere. It was That is, it is the current situation that artificial opal has not been considered so far.

[0003]

DISCLOSURE OF THE INVENTION The present invention uses a natural opal that is transparent and is colored in a rough stone whose base material is colorless, yellow, or blue, and rarely red. In view of the fact that it is a structure in which an array of molecules that optically separates, interferes with, and reflects the spectrum of light is formed, an artificial opal having a similar mechanism is provided. In order to bring out the peculiar soft shine of that opal, we must rely on means to separate, interfere, and reflect the spectrum of light, which cannot be obtained by direct reflection of light.

[0004]

In order to achieve the above object, in the present invention, as a means for separating, interfering, and reflecting the spectrum of light, an array of molecules that optically separates, interferes, and reflects the spectrum of light is already used. Since a multiple polymer film (trade name: Aurora film, Marl film, etc.) in which is formed has already been developed, it was used, and a transparent liquid resin was used as a main raw material by coloring it. That is, wrinkles are formed on the multiple polymer film (creasing has the effect of enhancing the interference effect of light, and in the present invention, all wrinkles are used except for cutting into fine pieces.) This is colored and transparent. A means for molding and curing by embedding in a different liquid resin was used.

[0005]

The artificial opal produced by the above-mentioned method has an array of molecules that optically separate, interfere and reflect the spectrum of light in advance in the transparent liquid resin which is the main raw material. Since the multi-polymer film is buried, when the light hits it, it splits the spectrum of light by the mechanism exactly the same as natural opal, interferes, reflects and shines, and the multi-polymer film is surrounded by liquid resin. When it is exposed, it has a much more strange glow than when it is in the air, and it has the effect of creating a soft, strange glow and atmosphere that is almost indistinguishable from natural opal. In particular, when combining a yellow-based multiple polymer film and a liquid resin colored in blue, it is extremely splendid and wonderful of a super-high-quality natural black opal that has a greenish tinge with a vivid combination of yellow and blue. It has the effect of producing a tremendous brilliance and attracts people. This is one important feature of the present invention. Brilliant fire opal can be obtained by using a yellow multi-layer polymer film and a liquid resin colored red.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Three examples are given as examples of the present invention, which will be sequentially described with reference to the drawings.

The production of the opal gemstone of the first embodiment will be described. In FIG. 1, 1 is a rubber mold made of silicone rubber having holes 2 for gems, and 3 is a wrinkled yellow multi-polymer film cut in the shape of a plane cross section of the gem-like holes 2. 3 is a multi-polymer film piece, and as shown in FIG. 3, 4 is a liquid epoxy resin mixed with a curing agent and a blue colorant, which is injected into the hole 2 of the rubber mold 1. Further, the multiple polymer film 3 is also embedded in the resin in a substantially planar manner. After the resin has hardened in this way, it can be taken out of the rubber mold to produce an artificial opal gem.

The second embodiment will be described with respect to an example in which an opal is directly molded and attached to a medal. FIG. 4 shows a medal with a gold heart 6 in the center and a gold ring 5 on the circumference.
The artificial opal is to be molded and mounted in the concave portion 7 between the gold ring and the heart. First, a multi-polymer film piece 8 having a shape that exactly fits in the recess 7 of FIG. 4 is cut out from the yellow multi-polymer film having wrinkles as shown in FIG. 5, and further, a slit 9 is formed around the multi-polymer film piece 8 with scissors. After that, in the same manner as in the first embodiment, the liquid epoxy resin 10 is injected into the recess 7 as shown in FIG. 6, and the multiple polymer film 8 is planarly embedded therein. By molding in this way, the resin 10 is firmly adhered to the concave portion 7 and the multi-polymer film piece 8 has the cut groove 9, so that the resin above the multi-polymer film surface passes through the cut groove 9. The resin underneath is firmly connected and never comes off. In this way, the artificial opal is molded and mounted between the heart 6 and the gold ring 5.

In the third embodiment, if a thin opal plate is molded and manufactured and heated to about 100 ° C., it becomes soft and can be easily cut with scissors. Therefore, by cutting this into the desired shape and adhering it to the desired object, an article with a fine artificial opal decoration is completed. This embodiment will be described with reference to the drawings. FIG. 7 shows a rubber mold 11 made of silicone rubber. In addition, a resin similar to that of the first embodiment is mixed with a thin and finely cut multi-polymer film (for example, aurorayan product name) and injected to form an opal thin plate 12 as shown in FIG. Next, from this thin plate, a cutout piece fitted in the recess 18 of the handle 17 of the fork shown in FIG.
As shown in FIG. 9, punching with a press, that is, punching into the shape of the recess 18 of the handle 17 of the fork on the thin plate 12,
Reference numerals 13, 14 and 15 are the holes for removing the holes, and 16 is an artificial opal piece. Fork handle 1 of this opal piece
By embedding and adhering it in the recesses 18 on both sides of 7, a pattern fork with the shine of opal is completed. Needless to say, the thin plate is heated to the above-mentioned high temperature during cutting. In addition, an example of a multi-polymer film cut into long and narrow pieces was given, but this one produces a distinctive brilliance unlike the case of a single film. Of course, the multi-polymer film need not be finely cut.

[0010]

Since the present invention is manufactured and constructed by the method as described above, it has the following effects.

The artificial opal produced by the method of the present invention has a mechanism of separating, interfering and reflecting the spectrum of light, which is exactly the same as that of natural stone, so that the soft opal is very close to that of natural stone. It creates a radiance that attracts people. Also, because it can be manufactured artificially,
It can be manufactured in any size and shape, and can be mass-produced, and it can also manufacture large things that do not exist in nature. In particular, the present invention, when combining a yellow-based multiple polymer film and a liquid resin colored in blue, with a wonderful greenish brilliance of the finest natural black opal,
It creates an atmosphere, and it is possible to artificially provide a large amount of black opal luxury products that are rare in natural products.
It can be easily obtained at low cost, and it can decorate more people's fingers beautifully. In addition, the artificial opal plate can be cut into any shape by hand or by a press for mass production, and can be widely used for decoration. The present invention has the effect of bringing a wide range of beauty to the decorative world and contributing.
