Description

[Detailed Description of the Invention] The present invention relates to a chemiluminescent material that is utilized in many applications.

Chemiluminescence is a substance that is brought to an excited state through the reaction of a certain oxalic acid ester and an oxidizing agent, and then changes to the ground state, emitting visible light. -Trichloro-6-carbobutoxyphenyl) oxalate ester, a solution of bis-9.10-phenylethynylanthracene dissolved in dibutyl phthalate (hereinafter referred to as oxalate ester), hydrogen peroxide and a catalyst such as sodium salicylate, and dimethyl phthalate. There is a combination with a solution dissolved in (hereinafter referred to as an oxidizing agent). Many uses have been developed for luminescent materials that apply chemiluminescence, as they do not require a power source or generate heat, but all conventional luminescent materials have a cylindrical luminescent method. By bending or otherwise deforming the container, the capsule inside is ruptured, and the chemical substance inside the capsule is mixed with the chemical substance inside the cylindrical container outside the capsule, causing chemiluminescence. Therefore, it had the following drawbacks.

○B. The container must be deformed by external force.

○B The material of the cylindrical container must be chemically stable and flexible.

○C The chemiluminescent liquid often leaked due to cracks in the container or fragments of the capsule being stuck in the container.

○D If the container is deformed, it will not completely return to its original shape.

The present invention aims to provide a chemiluminescent substance that eliminates the above-mentioned drawbacks, and the gist thereof is to place A of two substances A and B that exhibit a chemiluminescent phenomenon when mixed in a light-transmissive outer container 1. A shape memory alloy 3 is filled into a breakable capsule 2, and the other substance B is sealed in an outer container 1 outside the capsule, and the shape memory alloy 3 is plastically deformed at a temperature below a certain temperature. This chemiluminescent material is characterized by having a structure in which the capsule ruptures when the memory alloy 3 returns to its pre-deformed shape due to a temperature change.

Shape memory alloy is a phenomenon in which a certain type of alloy is plastically deformed by deformation processing, and then when it is heated, the shape of the alloy returns to its original shape before plastic deformation. This phenomenon is caused by martensitic transformation, specifically thermoelastic martensitic transformation in which the difference between the transformation temperature and the reverse transformation temperature is small, and its reverse transformation. NiTi is currently a practical alloy.
Alloys and copper alloys are known.

The present invention will be described in detail below with reference to the drawings. FIGS. 1 to 9 show an example of a combination of a capsule and a shape memory alloy.

1 to 5 each show a capsule containing a memory alloy. FIG. 1 shows a structure in which a straight alloy returns to its curved shape before plastic deformation when heated. In Fig. 2, it is plastically deformed into a U-shape, which returns to a straight shape when heated. In Fig. 3, the structure is one in which plastic deformation is applied to shrink in the length direction, and the structure expands to its original shape when heated. Fourth
The figure shows a structure that has been plastically deformed into a meandering shape, but returns to a straight shape when heated. FIG. 5 is a modification of FIG.

In any case, the ones in Figures 1 to 5 have a structure in which the shape memory alloy that has been plastically deformed and placed in the capsule cannot be accommodated in the space inside the capsule when it returns to its original shape before plastic deformation by heating. If the structure is like this, it is not limited to the structure shown in the drawings.

The capsules shown in FIGS. 6 to 9 have a shape memory alloy attached to the outside of the capsule. Figures 6 and 7
The figure shows a capsule containing a memory alloy that has been plastically deformed into a horseshoe shape, and which returns to its shape with a smaller inner diameter when heated. FIG. 8 shows a structure in which the memory alloy shown in FIG. 1 is attached to the outside of the capsule, and the linear alloy returns to its curved shape before plastic deformation by heating. FIG. 9 shows a structure in which a memory alloy is wrapped around a capsule and returns to its original straight shape when heated.

In any case, in the cases shown in Figures 6 to 9, when the shape memory alloy attached to the outside of the capsule is plastically deformed and returned to its original shape before plastic deformation by heating, the capsule maintains its own shape. If the structure is like this, it is not limited to the structure shown in the drawings.

Note that the shape memory alloy may be used as it is, or may be surface coated to make it chemically stable.

The items shown in FIGS. 1 to 9 above are placed in a light-transmissive outer container 1. An example of this storage form is shown in FIGS. 10 to 13. In each case, a combination of a capsule and a memory alloy shown in FIG. 1 was used as a representative example.

In Fig. 10, 2-11 capsules are placed in the outer container 1, and if an oxidizing agent is placed in the capsule 2-1, an oxalic acid ester is placed in the outer container 1 outside the capsules. put in.

In Figures 11 and 12, capsules 2-1, 2-
2 into outer container 1, capsules 2-1, 2-2
The oxidizing agent is put in one of the two, and the oxalic acid ester is put in the other. An oxidizing agent or oxalic acid ester is filled into the outer container 1 outside the capsules 2-1 and 2-2. Note that there are cases in which no substance is filled in the outer container outside the capsule.

Figure 13 shows capsule 2 inside capsule 2-1.
-2, and the chemiluminescent substance filling is the same as above. The light-transmitting outer container 1 is made of a heat-stable and chemically stable material, and is hard and transparent. Typical examples include glass and hard plastic. The shape of the outer container 1 may be rod-like, three-dimensional, planar, etc. depending on the use and purpose.

In the present invention having the above configuration, first, the outer container 1 is heated using hot air, gas, hot water, or other heat source, and the plastically deformed shape memory alloy 3 in the outer container 1 is heated to a certain temperature. When the shape of the alloy returns to its original shape before plastic deformation, the capsule 2 is ruptured. The substance inside the capsule and the substance inside the outer container mix, and chemiluminescence starts due to the reaction.

As described above, the product of the present invention automatically generates chemiluminescence when the temperature changes to a higher level, and has the effect of being widely usable for disaster prevention, signs, cash registers, and other stirrers.
