However, as is apparent from the great damage to museums and individual collectors caused by the Great Hanshin Earthquake, the conventional method effectively protects ceramics and the like in the event of an earthquake. I couldn't. On the other hand, insurance coverage may be considered, but there is a problem that not only the conditions of coverage are too strict, but the amount of coverage is too small. In addition, most non-life insurance companies do not accept earthquake insurance.
And, above all, for collectors and others, art works that are collections cannot be exchanged for money. Therefore, museums and individual collectors have no choice but to protect themselves, and a simple and reliable method of preventing damage has been desired. The present invention has been made to solve these problems.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a schematic process diagram of a first embodiment of a method for preventing damage to a ceramic or the like according to the present invention. Hereinafter, the damage prevention method of this embodiment will be described in chronological order from to. As shown in FIG. 1A, a pottery or the like (a dish is shown as an example in FIG. 1) 1 is dipped in a hydrophilic solution 2, for example, polypropylene glycol or diglycerin. In addition, it is preferable to preheat the pottery 1 and the like to the polymerization temperature of the lipophilic monomer described later in advance, because the steps described below are easily performed. As shown in FIG. 1 (B), a lipophilic synthetic resin, for example, a monomer such as methyl methacrylate resin or a semi-polymerized monomer 3 is injected into the ceramics 1 whose outer peripheral surface is coated with a hydrophilic solution 2. Put in the mold 4. The monomer or the semi-polymerized monomer 3 may be injected after the pottery 1 or the like is placed in the mold 4. A highly transparent synthetic resin is preferably used. As shown in FIG. 1 (C), after polymerizing the monomer or the semi-polymerized monomer 3 in which the pottery 1 is buried,
As shown in FIG. 1D, the mold 4 is taken out. As a result, the solution 2 having a hydrophilic group in the lipophilic synthetic resin 30
The ceramics 1 etc. will be stored through the.

FIG. 2 shows a second embodiment of the method for preventing damage to a ceramic or the like according to the present invention. Hereinafter, the damage prevention method of this embodiment will be described in chronological order from to. As shown in FIG. 2B, two lumps 31 and 3 of lipophilic synthetic resin having a size suitable for the size of the ceramics 1 or the like are provided.
2 Prepare. For this, the lump 30 of the synthetic resin polymerized in the mold 4 as described in the first embodiment may be cut into two pieces (FIGS. 2A and 2B). Alternatively, it may be produced by separately polymerizing with a mold. In any case, the two synthetic resin lumps 31 and 32 are in contact with each other and can be joined. Spaces 31b and 32b, which are slightly larger than the pottery 1 and the like, are formed on the joint surfaces 31a and 32a of the respective lumps 31 and 32 when the two lumps 31 and 32 are joined. That is, a space having a size suitable for the ceramics 1 and the like, and a space for allowing the hydrophilic solution 2 that functions as a buffer to be injected are added, and then the joint surface is hollowed out. Whether the ceramics or the like 1 is arranged in the spaces 31b and 32b, the joint surfaces 31a and 32a of the respective lumps 31 and 32 are brought into contact with each other, and the same monomer as the synthetic resin 30 or the semi-polymerized monomer 3 is injected to cause polymerization. Glue with glue. A hydrophilic solution 2 is injected between the ceramics 1 and the lumps 31 and 32. This includes, for example, FIG.
As shown in (C), it is performed by discharging the air from one end and injecting the hydrophilic solution 2 from the other end.
The hydrophilic solution 2 preferably has the same or similar optical refractive index as the synthetic resin 30 (31, 32). The same monomer as the synthetic resin 30 used for the production of the lumps 31 and 32 or the semi-polymerized monomer 3 is injected into the inlet and outlet of the air vent passage used in the previous step and the passage for injecting the solution to polymerize and close the same. . It should be noted that a plug having a size suitable for the passage and made of the synthetic resin 30 used for manufacturing the lumps 31 and 32 is used, and the monomer or the semi-polymerized monomer 3 is applied around the plug. , The space 31b, 32b
May be sealed. As a result, as shown in FIG. 2D, the ceramics 1 and the like are stored in the lipophilic synthetic resin 30 via the solution 2 having a hydrophilic group. According to the method of the second embodiment, since the prepolymerized synthetic resin 30 is used and the solution 2 is interposed between the synthetic resin 30 and the synthetic resin 30, heat is not applied to the pottery 1 and the like, which is preferable.

Next, the usage state of the product in which the ceramics 1 is embedded in the synthetic resin 30 manufactured by these methods will be described. By using a highly transparent material such as methyl methacrylate resin as the synthetic resin 30, it is possible to clearly see the ceramics 1 or the like. Further, since the ceramics 1 and the like are housed in the synthetic resin 30 and the hydrophilic solution 2 interposed between the ceramics 1 and the synthetic resin 30 functions as a buffer, even when an earthquake occurs Effectively protect ceramics, etc. 1. Further, since the ceramics 1 and the like are covered with the synthetic resin 30, the exhibition of the ceramics and the like 1 can be further enhanced, and the ceramics and the like 1 itself
It is also useful to prevent theft as compared to the case of displaying as a single item. In addition, adding a flame retardant to the synthetic resin 30,
If a flame-retardant material is applied to the finished synthetic resin, the flame-retardant effect can be exhibited and the ceramics 1 etc. can be protected from fire. When it is desired to take out the ceramics 1 or the like from the synthetic resin 30, after the synthetic resin 30 is removed by cutting in proximity to the ceramics 1 or the hydrophilic solution, the synthetic resin 30 is immersed in a liquid having a dissolving power, By swelling and removing the synthetic resin 30, the ceramics 1 or the like can be taken out without being damaged. Note that, for example, when the synthetic resin 30 is a methyl methacrylate resin, toluene or the like can be used as the solution.

The method for preventing damage to the ceramic or the like 1 according to the present invention is not limited to the configuration of the above-described embodiment, but can be changed as appropriate.
For example, in each of the above embodiments, a lipophilic synthetic resin 30 (monomer or semi-polymerized monomer) covering the ceramics 1 is used, and the solution 2 interposed between the synthetic resin 30 and the ceramics 1 is hydrophilic. Although the example using the above is shown, the configuration opposite to this may be used. That is, the synthetic resin 30 may be hydrophilic, the solution 2 may be lipophilic, and the two may have opposite properties. Further, the bottom surface or the like of the synthetic resin 30 that covers the ceramics 1 may be mirror-finished. This makes it possible to more easily see the ceramic ware 1 or the like. Furthermore, the material of the synthetic resin 30 is not limited to the above-mentioned methyl methacrylate resin, but polycarbonate, polystyrene, or the like can be used.

[0009]

As described above in detail, according to the method for preventing damage to a ceramic or the like according to the present invention, the ceramic or the like can be effectively protected even when an earthquake occurs. Further, since the ceramics and the like are stored through the solution having a property that is contrary to the property of the synthetic resin, there is no fear of damaging the ceramics or the like when taking out the ceramics or the like.
