The present invention relates to a gel-like instant cooling and low-temperature flexible cold storage agent that maintains relative flexibility and can be applied to fields where it is difficult to use ordinary frozen cold storage agents. (B) Prior Art and Problems Regarding portable refrigerants, ammonium chloride, ammonium sulfate, ammonium sulfate,
By utilizing the negative latent heat when sodium sulfate, sodium sulfite, etc. are dissolved in water, it is used for leisure activities such as fishing, sea bathing, sports, and as an emergency cold pack for bruises, napkins, headaches, and toothaches. However, these applications are limited to fields that utilize short-term cold retention effects. Furthermore, if the covering bag or container is damaged during use, the contents may flow out and wet or stain the object to be cooled. In addition, regarding the gel-like cold storage agent that has been conventionally used by freezing in a refrigerator,
279, a gel-like material obtained by mixing galactomannan, starch, propylene glycol, poval, etc. with water is generally sealed in a film of polyethylene or the like. The use of this gel-like cold storage agent is almost the same as that of the above-mentioned portable coolant. These refrigerator cooling type regenerators can maintain the cold effect for a longer period of time than portable refrigerants. Since it exhibits the same hardness as ice in a frozen state, it has the disadvantage that it cannot be applied to areas that require flexibility and deformation, that is, localized areas. (C) Problems to be Solved by the Invention The present invention makes it possible to achieve the cold preservation effect of a gel-like cold storage agent that is used by freezing it in a conventional refrigerator without pre-cooling it. This improves the drawback that when the container of a portable cold storage agent is damaged, the contents may wet or stain the object to be cooled. In addition, the present invention is not only effective as a portable cold storage agent, but also
By cooling it again in the refrigerator, it can be used repeatedly as a refrigerator cooling type cold storage agent. Furthermore, conventional refrigerator cooling type cold storage agents have the same hardness as ice when frozen, so they have the disadvantage of being difficult to apply to cold storage in fields that require small spaces or flexibility or deformation. Because it is relatively flexible even at low temperatures and can be crushed relatively easily even when frozen, it has become widely available. [Structure of the Invention] (A) Means and Features for Solving the Problem The present invention provides coolants that have negative latent heat when dissolved in water, ammonium nitrate, ammonium chloride, sodium nitrate, potassium nitrate, urea nitrate, and thiosulfuric acid. sodium, sodium chlorate,

30.0-99.9% of one or more types of aspartic acid and sodium alginate as a gelling agent. One or more of potassium alginate, ammonium alginate, propylene glycol alginate, carrageenan, polymeric water-absorbing resin, hydrophilic carboxyvinyl polymer, and polyvinyl alcohol at 0.1
- 50.0% and further add 0 to 99.9% of one or more of calcium chloride, sodium chloride, potassium chloride to lower the freezing temperature and mix until the whole is homogeneous, water, Seawater, ethylene glycol. 20-8% of one or more of propylene glycol, diethylene glycol, glycerin, and ethyl alcohol
The first feature is to obtain a gel-like composition that is mixed and cooled to a ratio of 0%. The second feature of the present invention is that when the gel-like composition is sealed and packaged in an airtight container such as a polyethylene film and frozen in a refrigerator, it does not freeze hard like conventional cold storage agents, but becomes flexible. The point is that it maintains a hardness that makes it easy to deform. Therefore, after using crystal as a gel-like portable cool storage agent,
It can be reused as a refrigerator-freezing type cold storage agent, and because it maintains flexibility or is hard enough to easily deform, it can be applied to keep any local area cold, which is a feature not found in conventional cold storage agents. It is. (R) Effects and Examples The present invention will be explained in more detail with reference to Examples below. Example When 57 parts by weight of water was added to 36 parts by weight of ammonium nitrate, 0.5 parts by weight of boric acid, 1.51 parts by weight of propylene glycol ester alginate, 2 parts by weight of polyvinyl alcohol and 3 parts by weight of sodium chloride and stirred, the temperature of the mixture At the same time, a gel-like composition was obtained. Table 1 shows the cold storage effect of the gel composition (250 g) thus obtained at room temperature (23°C). The gel instantaneous cold storage agent of this example is shown in Table 1. It shows almost the same cold storage effect as a commercially available portable cold storage agent that is not in gel form, and is superior to commercially available products in terms of safety due to its gel form. Next, the gel composition obtained in this example was put into a polyethylene bag, heat-sealed, and placed in a refrigerator.
It was cooled to ℃ and after 3 days it was taken out and its hardness was compared with a commercially available product. The results are as follows. Example: When strong pressure was applied with fingers, a plate-shaped frozen object broke into small pieces. Commercial product: It froze like ice and did not break even when pressure was applied with fingers. Therefore, this example is effective as an ice pack for localized areas because it easily deforms even after freezing due to the plasticizing effect of the ingredients. [Effects of the Invention] (11) The first effect of the present invention is that despite the fact that it is gel-like as shown in Table 1 of Examples. (2) The second effect of the present invention is that when the present gel composition used as an instantaneous cold storage agent is reused as a refrigerator cooling type cold storage agent, it has a cold storage effect. Unlike other types, it maintains its hardness so that it easily deforms even after freezing.
