Description

【００２８】
表１の結果が示すように、エポキシ樹脂Ａおよびエポキシ樹脂Ｂの結果は、エポキシ樹脂Ｃと異なり硬化後の遺骨片に破損が認められず、またエポキシ樹脂Ｃよりも硬化時の最高温度が低いため、成型用樹脂としてより適していることが分かった。
【００２９】
ところが、エポキシ樹脂Ａおよびエポキシ樹脂Ｂを用いた場合においても、硬化後の遺骨片の表面に、微細な気泡や粉末が認められた。微細な気泡は、遺骨内部に含まれていた空気が樹脂硬化時に表面に現れたものであり、微細粉は、遺骨表面に付着していた火葬時の灰であると考えられた。そこで、これらを生じさせない目的で、成型用樹脂による硬化に先立って前処理を試みることとし、実験を施した（実験２）。実験２で用いた樹脂は、実験１と同じくエポキシ樹脂Ａ、エポキシ樹脂Ｂ、およびエポキシ樹脂Ｃであり、その方法を以下に示す。
【００３０】
まず、長さ１０〜１５ｍｍ、幅５〜１０ｍｍ、厚さ１〜５ｍｍ程度の薄片状の火葬された猫の遺骨片３つをエタノールに３分間浸漬、洗浄して表面の汚れを除き、エタノールを蒸発乾燥させた。その後、硬化剤Ａ、硬化剤Ｂおよび硬化剤Ｃをそれぞれエポキシ樹脂Ａ、エポキシ樹脂Ｂ、およびエポキシ樹脂Ｃに加え（使用量はいずれも先の実験１と同量）、それぞれ静かに攪拌した。これらを、それぞれ同一形状の容器に入れ、さらに同種の遺骨片を各容器に入れて各樹脂に浸漬させた。続いてこれらの容器を、デシケータに入れて密閉空間に置き、真空ポンプにより約１０分間、６．７〜１３．３ｋＰａ程度に減圧した。その後、ゆっくりと常圧に戻し、容器から遺骨片を取り出し、それぞれの遺骨片表面の樹脂の固着が確認されるまで静置した。こうして処理された遺骨片の表面を観察し、先の実験１と同様に、これらの遺骨片と前処理に用いたエポキシ樹脂とによる硬化実験を行った（エポキシ樹脂Ａで前処理を施した遺骨はエポキシ樹脂Ａと共に硬化させた。エポキシ樹脂Ｂおよびエポキシ樹脂Ｃについても同じ）。実験２の結果を表２に示す。
【表２】

【００３１】
実験２の結果と、実験１の結果とを比較すると、前処理を施すことにより硬化後の遺骨片表面がきれいに仕上げられることが明らかとなった。この効果は、遺骨表面に付着していた微細粉がエタノール洗浄により除去され、遺骨内部の微細な空孔内に含まれていた空気が、真空含浸された樹脂に置換されたことによると考えられた。さらに、エポキシ樹脂Ｃについての実験１と実験２との結果を比較すると、前者においては一部に破損が認められたものの、後者においては認められないことから、この前処理が表面清浄化のみならず、遺骨の保護にも有効であることが確かめられた。こうして、前処理の効果が確認されたため、本発明における製造方法の最初の段階において、保護処理として遺骨に施すこととした。
【００３２】
先述の実験１および実験２の結果より、保護処理で使用する保護用樹脂としてエポキシ樹脂Ａを選択し、成型用樹脂としてはエポキシ樹脂Ｂを選択した。この選択は、エポキシ樹脂Ａおよびエポキシ樹脂Ｂが、エポキシ樹脂Ｃよりも硬化時の温度上昇が低いため、遺骨の保護に適していることに加え以下の理由による。すなわち、エポキシ樹脂Ａの粘度、約２６０ｃＰ（＠２０℃）が、エポキシ樹脂Ｂの約７００ｃＰ（＠２０℃）やエポキシ樹脂Ｃの５５０ｃＰ（＠２０℃）よりも低いため保護用樹脂としての使用に適していることと、エポキシ樹脂Ｂは、硬化時間が最も長いことから、成型用樹脂としての使用により適していることによる。

DETAILED DESCRIPTION OF THE INVENTION
Below, the accessory manufacturing method which is embodiment of this invention is demonstrated with reference to drawings. FIG. 1 is a diagram illustrating a process for protecting a remains as a protective agent.
[0010]
As a pretreatment process, the remains 10 are protected. The method is shown below. First, the remains 10 are washed with a washing liquid (ethanol or the like), and the washing liquid is dried. Thereafter, the protective epoxy resin 12 which is a protective resin in which the curing agent is uniformly mixed is put in the container 14, and the remains 10 are put in the container 14. Then, the vacuum pump 18 is connected to the exhaust valve 21 of the desiccator, and the internal space of the desiccator 16 is decompressed. The degree of reduced pressure (atmospheric pressure) at this time is measured by the vacuum gauge 23. Thereafter, air is introduced into the desiccator 16 from the intake valve 19 to return to normal pressure, and the remains 10 are removed from the container 14. By this operation, the protective epoxy resin 12 is impregnated into the surface of the remains 10 and the fine pores communicating with the surface. As a result, the fine vacancies are filled with the protective epoxy resin 12 in place of the air previously contained.
[0011]
The protective epoxy resin 12 that covers the surface of the remains is required to be quickly impregnated into the fine pores of the remains, so that the viscosity is preferably low, and the air in the fine pores of the remains is replaced. If it is judged that it is difficult to be applied, an organic solvent such as acetone may be uniformly added to the protective epoxy resin 12 to further reduce the viscosity, and then the protective treatment may be performed.
[0012]
After the decompression process, the remains 10 are removed from the container 14 and the remains 10 are allowed to stand to cure the protective epoxy resin 12 covering the surface of the remains 10. By the curing of the protective epoxy resin 12, the protection process (pretreatment process) for protecting the surface of the remains is completed. The standing time for curing the protective epoxy resin 12 varies depending on the state of the remains 10, and when the remains 10 are fragile, the protective epoxy resin 12 needs to be sufficiently cured, so that the longer one is longer. Preferably, when the remains 10 are robust, the remains 10 may be shortened and immediately proceed to the subsequent molding process (main process).
[0013]
FIG. 2 is a diagram illustrating a process of molding an accessory using the embedded mold 20 while embedding the remains 10 subjected to the protection process in a predetermined position.
[0014]
In the molding process, the remains 10 subjected to the protection process are embedded in a predetermined position with a molding material to mold an accessory. First, a molding epoxy resin 22 in which a curing agent is uniformly mixed in advance is injected into the embedded mold 20, and the decorative article 24 is arranged at a predetermined position. And before hardening the epoxy resin 22 for shaping | molding, the remains 10 to which the protection process was performed are left still near the center which is a desired position, fully immersed in the epoxy resin 22 for shaping | molding. When the molding epoxy resin 22 including the remains 10 and the decorative article 24 is cured, the molding epoxy resin 22 including the remains 10 and the decorative article 24 is integrated and embedded as a completed accessory 20. Take out from. In addition, if a decorative article having a complicated shape is inserted into the resin, there is a possibility that air may be mixed and the air cannot be deaerated. Therefore, the decorative article 24 is first placed at a desired location of the embedded mold 20, and thereafter Solid resin 22 may be injected.
[0015]
The protective epoxy resin 12 and the molding epoxy resin 22 are preferably cold-curing resins that do not require a high temperature for curing in order to maintain a stable state without causing deformation or discoloration of the remains. Moreover, the thing with a small temperature rise by the hardening reaction at the time of hardening is more preferable.
[0016]
Further, as described above, the protective epoxy resin 12 needs to be quickly impregnated into fine pores of the remains, so that the viscosity is preferably low. It is more preferable that it satisfies the condition of at least 550 cP (@ 20 ° C.) or less and is 260 cP (@ 20 ° C.) or less.
[0017]
In addition to the above-described conditions, the molding epoxy resin 22 preferably has a curing reaction that progresses gradually, that is, has a long curing time, in order to suppress a temperature rise due to heat generation of the curing reaction. In general, it is possible to extend the curing time by reducing the amount of the curing agent. However, if the amount of the curing agent is extremely reduced, it is difficult to adjust the curing time. In addition, the molding epoxy resin 22 is preferably one whose shape does not change before and after curing in order to mold an accessory having a predetermined shape.
[0018]
In the present embodiment, two types of different epoxy resins that satisfy these conditions are used as the molding epoxy resin 12 and the protective epoxy resin 22. A resin other than an epoxy resin may be used, or a resin other than a resin may be used.
[0019]
According to the present embodiment, the surface of the remains 10 is covered and protected with the protective epoxy resin 12, so that the remains 10 are not discolored or damaged in the curing reaction for accessory molding with the molding epoxy resin 22. It does not occur and the state before the curing reaction for molding is maintained.
[0020]
In the present invention, the shape and size of the accessory to be molded can be freely set by adjusting the shape of the embedded mold 20 and the amount of the molding resin 22.
[0021]
In the accessory manufactured by the manufacturing method of the present invention, the transparent protective epoxy resin 12 or the molding epoxy resin 22 is used so that the remains and the like embedded therein can be visually recognized from the outside. However, as long as the internal remains can be visually recognized from the outside, these hues are not necessarily limited to transparent, and may be translucent or low in transparency.
[0022]
【Example】
Below, the Example of the manufacturing method of the accessory of this invention is described.
[0023]
A piece of cremation-shaped cremation cat whose length is 10-15 mm, width 5-10 mm, and thickness 1-5 mm is immersed in ethanol for 3 minutes, cleaned by brushing to remove dirt on the surface, Ethanol in the voids inside the remains was evaporated to dryness. Thereafter, bisphenol-A- which is an epoxy resin in which 20 g of a curing agent, 2-methyl-1,5-pentamethylenediamine, diethylamine, and propyleneamine mixture (manufactured by Struers, hereinafter referred to as curing agent A) is uniformly mixed. 140 g of epichlorohydrin resin (specific 20 from Struers, hereinafter referred to as epoxy resin A) was taken in a container, and the remains were placed in the container and completely immersed in epoxy resin A. The remains were placed together with the epoxy resin A containing the curing agent A in a sealed space inside the desiccator together with the container, and the pressure was reduced to about 6.7 to 13.3 kPa over about 10 minutes by a vacuum pump. Then, it released from the pressure reduction state, took out ashes from the container, and left still for about 30 minutes, and confirmed hardening of the epoxy resin A which coat | covers the remains surface.
[0024]
A decorative article is previously arranged at a predetermined position of a rectangular parallelepiped embedded mold made of silicon resin, and N, N-bis (2-aminomethyl) -1,2-ethane as a curing agent is placed in this embedded mold. Weight ratio of bisphenol-A-diglyl sidyl ether resin and ethylene glycol diglyl sidyl ether resin, which is an epoxy resin in which 100 g of diamine (manufactured by I.T. Was gently injected 200 g of a 9: 1 mixture (Debcon ET manufactured by ITW Industry, hereinafter referred to as Epoxy Resin B). And after leaving still for about 2 hours and confirming that the epoxy resin B containing the curing agent B has not yet been cured, the remains covered with the cured epoxy resin A are embedded at the desired position. It was left in the vicinity of the center.
[0025]
After 24 hours, since the curing of the epoxy resin B including the remains and decorations was completed, the epoxy resin B was taken out of the embedded mold as a finished accessory.
[0026]
[Experimental example]
For the purpose of selecting a material suitable for the molding material in the present invention, an evaluation experiment was performed in which three types of epoxy resin, acrylic resin, and polyester resin were cured together with the remains. As a result, the epoxy resin has the lowest maximum temperature during curing, the longest curing time, and no change in shape before and after curing, so it should be the most suitable molding material among the evaluated resins. I understood. Therefore, in the present invention, an epoxy resin is used as a molding material (molding resin), and an evaluation experiment was performed to select a more appropriate one from a plurality of epoxy resins (Experiment 1). The method of Experiment 1 is shown below.
[0027]
In Experiment 1, it was recommended for each of three types of resins: epoxy resin A, epoxy resin B, and epoxy resin bisphenol-A-diglyl sidyl ether resin (Epofix made by Struers, hereinafter referred to as epoxy resin C). The recommended amount of curing agent is added. That is, for the epoxy resin A and the epoxy resin B, the same amount of the curing agent A and the curing agent B are used as in the previous embodiment, respectively, and for the epoxy resin C, triethylenetetraamine (Struers) Manufactured, hereinafter referred to as curing agent C), and 40 g of curing agent C was added to 300 g of epoxy resin C. After these curing agents were added to the respective resins, they were gently agitated so as not to mix air. And three pieces of the remains of the cremation-shaped cat which was about 10-15 mm in length, 5-10 mm in width and 1-5 mm in thickness were placed in three reaction containers of the same shape, respectively. A resin containing a curing agent was injected, and this time was set as the start of the experiment. The time required for curing from the start of the experiment was measured, and changes in shape before and after curing were confirmed. The results of Experiment 1 are shown in Table 1.
[Table 1]

[0028]
As shown in the results of Table 1, the results of the epoxy resin A and the epoxy resin B are different from the epoxy resin C in that no damage is observed in the remains after curing, and the maximum temperature during curing is lower than that of the epoxy resin C. Therefore, it turned out that it is more suitable as molding resin.
[0029]
However, even when epoxy resin A and epoxy resin B were used, fine bubbles and powder were observed on the surface of the remains after curing. It was thought that fine air bubbles appeared on the surface when the resin contained inside the remains was cured, and the fine powder was considered to be ash during cremation attached to the remains. Therefore, for the purpose of preventing the occurrence of these problems, an experiment was conducted by trying pretreatment prior to curing with a molding resin (Experiment 2). The resin used in Experiment 2 is epoxy resin A, epoxy resin B, and epoxy resin C as in Experiment 1, and the method is shown below.
[0030]
First, 3 flake-shaped cremation cat remains, 10-15 mm long, 5-10 mm wide and 1-5 mm thick, were immersed in ethanol for 3 minutes to remove the dirt on the surface. Evaporated to dryness. Thereafter, the curing agent A, the curing agent B, and the curing agent C were added to the epoxy resin A, the epoxy resin B, and the epoxy resin C, respectively (the amounts used were the same as in the previous experiment 1), and each was gently stirred. These were put in containers of the same shape, and the remains of the same kind were put in each container and immersed in each resin. Subsequently, these containers were placed in a desiccator and placed in a sealed space, and the pressure was reduced to about 6.7 to 13.3 kPa by a vacuum pump for about 10 minutes. Thereafter, the pressure was slowly returned to normal pressure, and the remains were removed from the container and allowed to stand until the resin on the surface of each remains was confirmed. The surface of the remains thus treated was observed, and in the same manner as in the previous experiment 1, a hardening experiment was performed using these remains and the epoxy resin used for the pretreatment (the remains subjected to the pretreatment with the epoxy resin A). Was cured together with epoxy resin A. The same applies to epoxy resin B and epoxy resin C). The results of Experiment 2 are shown in Table 2.
[Table 2]

[0031]
When the result of Experiment 2 was compared with the result of Experiment 1, it was revealed that the surface of the remains after hardening was cleanly finished by performing the pretreatment. This effect is thought to be due to the fact that the fine powder adhering to the surface of the remains was removed by washing with ethanol, and the air contained in the fine pores inside the remains was replaced with a resin impregnated with vacuum. It was. Furthermore, when comparing the results of Experiment 1 and Experiment 2 for epoxy resin C, some damage was observed in the former, but not in the latter. It was also confirmed that it was effective in protecting the remains. Thus, since the effect of the pretreatment was confirmed, it was decided to apply it to the remains as a protection treatment in the first stage of the production method of the present invention.
[0032]
From the results of Experiment 1 and Experiment 2 described above, Epoxy Resin A was selected as the protective resin used in the protection treatment, and Epoxy Resin B was selected as the molding resin. This selection is based on the following reasons in addition to the fact that epoxy resin A and epoxy resin B have a lower temperature rise during curing than epoxy resin C and are suitable for protecting the remains. That is, since the viscosity of epoxy resin A is about 260 cP (@ 20 ° C.) is lower than about 700 cP (@ 20 ° C.) of epoxy resin B and 550 cP (@ 20 ° C.) of epoxy resin C, it is suitable for use as a protective resin. This is because the epoxy resin B is suitable and is more suitable for use as a molding resin because it has the longest curing time.
[0033]
【The invention's effect】
As described above, according to the present invention, an accessory capable of protecting the embedded remains from damage or discoloration and maintaining the original shape is manufactured.
