2. Description of the Related Art It is common practice in a transparent resin-embedded specimen to embed a substance that easily changes in the air, such as a living body, in a transparent resin so that it can be stored for a long time. JP-A-57-77601, JP-A-61-293901, and JP-A-63-284101.
It is also described in Japanese Patent Publication No.

At this time, the resin used is transparent and
It is desired to have a gas barrier property as much as possible. Usually, an acrylic resin or a polyester resin is used, but an epoxy resin or a urethane resin can also be used. Although silicone rubber is a transparent resin, it is not suitable as an embedding resin for an embedding product that requires preservability because of its high gas permeability. Therefore, silicone rubber is mainly used for waterproof embedding of electrical equipment, etc., and even when used in the field of ornaments, its contents are limited to those that do not change when left in the air, such as metallic glass products. ing.

[0004] As described above, silicone rubber is not suitable as an embedding resin for living organisms or the like that require preservation. However, silicone rubber can contain a considerable amount of alcohol and the like, and is mixed with fragrance. Then, since the fragrance emanates slowly and continues to emit fragrance for a long period of time, the present inventor embeds the organism by using the silicone rubber mixed with the fragrance in combination with the conventional embedding resin, A method of manufacturing a resin-embedded object of a living body that allows the user to enjoy the scent while enjoying the living body in its original color was invented and applied for a patent (Japanese Patent Application No. 2-243985).

[0005] As described above, there is no known transparent resin-embedded specimen or ornament in which the embedded article can be easily taken out as required without damaging it.

[0006]

SUMMARY OF THE INVENTION The present invention relates to an article, which is an excavated article, a souvenir, or the like, which deteriorates in the air when it is turned into an exhibit. The purpose is to manufacture a transparent resin-embedded display that protects it and enables easy removal of the article without damaging it in the event of a need for detailed investigations, chemical analysis, etc. in the future. .

Means for Solving the Problems The present inventor has made intensive studies to solve the above-mentioned problems. As a result, the present inventors have found that a transparent resin, silicon rubber or silicon gel or a combination of both, which can be removed with a solvent, a glass or a gas barrier material. The present inventors have found that by using the three resins in combination, it is possible to prevent deterioration of the display item and to easily remove the display item at any time as necessary without damaging the display item, thereby completing the present invention.

That is, according to the present invention, a transparent resin film that can be removed with a solvent is applied to the entire surface of an article for display, such as excavated goods and souvenirs, and the outside is covered with a layer of silicon rubber or silicon gel or a combination of both. This is a method of manufacturing a transparent resin-embedded display, which is further covered with glass or a synthetic resin having gas barrier properties.

In the present invention, articles to be displayed, such as excavated articles and souvenirs (hereinafter referred to as "exhibits") are embedded in resin. First, the entire surface of the exhibits is dissolved and removed with a normal solvent. Apply a transparent resin film that can be used. As this transparent resin, shellac, acrylic resin, etc. are used, shellac is dissolved in alcohol and applied to the surface of the exhibit, and as the acrylic resin, a transparent transparent acrylic resin paint may be used. Apply to the surface of the exhibit. In some cases, both may be used in combination.

As described above, the transparent resin film that can be removed with a solvent is applied when the display article is directly covered with silicon rubber and silicone gel, which adheres to the display article surface, and it becomes necessary to take out the display article. This is because it is difficult to remove the display item without damaging it. If a transparent resin film that can be removed with a solvent is applied, the display item can be easily removed without damage.

As described above, the outside of the exhibit having the transparent resin film removable by a solvent is covered with a layer of silicon rubber or silicon gel or a combination of both. Silicon rubber can be easily removed by cutting with a knife or the like, and silicon gel can be easily removed with a spatula.In the present invention, silicone rubber or silicon gel or a combination of both is used. The layer which is the main layer of the embedding resin.

Since the silicone rubber and the silicone gel have high gas permeability, only the silicone rubber and the silicone gel have insufficient storage stability of the exhibited product, and the purpose of storage cannot be achieved. Therefore, in the present invention, after coating with a layer of silicon rubber or silicon gel or a combination of both, it is coated with glass or a synthetic resin having gas barrier properties. This glass or synthetic resin having gas barrier properties forms an outer layer, and corresponds to a case in an exhibit. Therefore, in actual production, glass or acrylic resin, polyester resin, urethane resin or epoxy resin is used in advance. It is preferable that the case and its lid are formed of resin or the like, and the process of covering with the silicon rubber or the silicon gel or a layer in which both are combined is performed in the case. That is, an exhibit with a transparent resin film that can be removed with a solvent is placed in the above case, silicon rubber or silicone gel is injected into the case, and the entire surface of the exhibit and the space of the case are filled, and then the lid is injected. Adhere to the silicone rubber or silicone gel.

Thus, since the outer layer is formed of glass or a synthetic resin having gas barrier properties, gas permeation is prevented, the purpose of preservation of the exhibited items is achieved, and it is necessary to take out the exhibited items. Since the outer layer can be peeled off from the silicone rubber or silicone gel that hits the inner layer, there is no inconvenience in taking out the display.

[0014]

According to the present invention, it is easy to deteriorate by using a transparent resin which can be removed by a solvent, silicone rubber or silicone gel or a combination of both, glass or a synthetic resin having gas barrier properties. The deterioration and damage of the mechanically fragile display is completely prevented. Then, when it becomes necessary to take out the exhibit, the exhibit can be easily taken out without damaging it.

[0015]

Embodiments of the present invention will be described below. Example 1 Structural wood pieces of a ship that had been in moist soil for a long time were put into a drying oven at 60 ° C., taken out when the surface was dry, and the entire surface of the wood pieces was coated with alcohol in which shellac was dissolved. Warm air is sent to evaporate the alcohol and make the shellac adhere to the piece of wood. Next, a transparent acrylic resin paint is applied and dried. This is put in a glass case, filled with silicone rubber, and then covered with a glass lid to adhere to the silicone rubber.

In the case where a piece of wood is large or has a complicated shape or a very fragile portion, the acrylic resin paint is applied and dried, and then a relatively thick silicon rubber film of the order of millimeters is applied. After that, it is put in a glass case, filled with silicon gel, and then covered with a glass lid to adhere to the silicon gel. This is because the coefficient of thermal expansion of silicon rubber is several times larger than that of glass or wood, and there is a risk that a piece of wood may be broken due to changes in room temperature during storage and display. There is no fear.

If it becomes necessary to take out the embedded wood piece, the outer wall case is peeled off, and in the case of silicone gel, it is removed with a spatula or the like, and then the silicone rubber is cut open with a scalpel to remove it. Acrylic resin and shellac are removed by successive immersion in alcohol.

Example 2 An iron sword excavated in a state in which the whole is completely rusted and has been separated into many small pieces. Thereafter, the steel sword is kept in a normal glass case in the room for more than two years. As time passes, each piece is further oxidized, and even if it is in a state where it is broken even by a small impact, an acrylic paint is applied over the surface to prevent rust and the like from adhering. If you move it as it is, it will fall apart, so apply silicone rubber with a large amount of curing agent,
A 3 mm thick coating is formed. When this film is completely cured, the iron sword is turned over and a film is formed on the back surface in the same manner as described above.

A case is made of a transparent acrylic plate, and a silicone rubber layer having a thickness of 5 to 10 mm is adhered to the inside of the case. An iron sword having the above-mentioned film formed therein is put into the case, and the silicone gel is filled and cured to a position 5 to 10 mm below the mouth of the case, and then silicone rubber is injected so as to fill the mouth of the case. Then, this is cured. At this time, the mouth is covered with an acrylic plate at the same time, and this is brought into close contact.

In this embodiment, the outside is an acrylic case,
The inside is silicon rubber, the inside is silicone rubber, and the iron sword is wrapped in silicone rubber and acrylic resin. Gels are indispensable to mitigate the effects of thermal expansion, but since it is not perfect to stop the permeation of water vapor, rubber and acrylic resin are the first with the purpose of supplementing this, but not only that, The inner rubber is to make it easier to take out the iron sword, and the outer rubber is to stop the spill if the acrylic case should be destroyed by the effects of thermal expansion.

Example 3 A tree nut that is black when wet with water, becomes gray when dried, and becomes scattered is sequentially immersed in alcohol and an acrylic monomer. Apply the material and air dry. Thereafter, the glass case is sealed in the same manner as in the first embodiment.

Example 4 The entire surface of a structure made of iron or other metal that has been degraded by a fire and that has been left alone for many years and has undergone considerable corrosion, as well as having a complicated shape and a size of several meters Then, a mixture of an acrylic monomer and its polymer is used to form an adhesion layer having a thickness greater than that of a normal coating film and a uniform thickness. Thereafter, it is sealed in an acrylic plate case in the same manner as in Example 2.
