Description

TECHNICAL FIELD The present invention is applied to uses such as engine coolant, transformer cooling fluid, grinding fluid, polishing fluid, floor heating heat medium, cold storage agent, heat storage agent, solar heating medium, etc. It can be used as a liquid base material or as a gaseous base material used in applications such as circulating fluid for floor heating, fluid for heat exchangers, refrigerant for home air conditioners, building air conditioners, and large freezers. It relates to a specific heat composition. For example, in the field of automotive coolants and transformer coolants, water has been used as a liquid high specific heat substance, and a freezing point depressant, a corrosion inhibitor, a stabilizer, a pH regulator, etc. have been added to this. Many have been implemented. Similarly, water is frequently used as a high specific heat base material in fields such as cold storage agents / heat storage agents, grinding fluids, polishing fluids, circulating fluids for floor heating or refrigerants. This is because water has the largest specific heat (lea 1 / g / ° C) of a substance and is easily available, as is also described by the phrase, "It is difficult to warm up, but it is difficult to cool down once it has warmed up." , And because of its excellent stability. For this reason, in the fields of automotive coolants, transformer coolants, regenerators, grinding fluids, polishing fluids, floor heating circulating fluids, heat storage agents, etc., their performance is evaluated and designed based on water. I was Disclosure of the invention The present invention breaks down the conventional wisdom that water has the highest specific heat, has a higher specific heat than that of water, and can be applied to a wide range of applications as a liquid or gaseous main material. The purpose is to provide things. First, the high specific heat composition according to claims 1 to 3 will be described. This high specific heat composition is used mainly for liquids such as engine coolant, transformer cooling fluid, grinding fluid, polishing fluid, heat medium for floor heating, cold storage agent, heat storage agent, and heat medium for solar. Or as a gaseous main material used in applications such as circulating fluid for floor heating, fluid for heat exchangers, refrigerant for home air conditioners, air conditioners for buildings, and large freezers. Performance such as cooling, heat storage, cold storage, and heating can be dramatically improved. As a substrate, when the high specific heat composition is applied to uses such as an engine coolant, a polishing liquid, a heating medium for floor heating, and a heat storage agent (when the substrate is a liquid), it is subjected to an electrostatic field treatment. Use water, glycols, or mixtures thereof. The water may be any water such as tap water, well water, ion-exchanged water. Glycols include ethylene glycol (EG), propylene glycol (PG), 1,3-butylene glycol, hexylene glycol (HG), ethylene glycol, glycerin, trimethylene glycol, butylene glycol, 1,1-dimethyl Preferred are ethylene glycol, 1,2-dimethylethylene glycol, propylethylene glycol, 2-butylethylene glycol, 2,2-dimethyltrimethylene glycol and the like. Of these, ethylene propylene glycol is particularly preferred in terms of solubility in water and corrosion prevention. The substrate of the present invention comprises the above-mentioned water, glycols, or a mixture thereof, It is obtained by processing. Electrostatic field treatment means that, for example, water, glycol or a mixture thereof to be treated is placed in a container placed in an ungrounded state, one electrode (for example, a carbon electrode) is placed in the container, and the other electrode is placed in the container. Is the static voltage

(For example, 1.7 kV) to form an electric field, and leave it as it is. When the high specific heat composition is applied to applications such as circulating fluid for floor heating, fluid for heat exchangers, refrigerant for home air conditioners, air conditioners for buildings, and large freezers (when the base material is gas), Water, glycol, or a mixture thereof, which has been subjected to an electrostatic field treatment as described above, is used as a substrate. The vaporization of the mixture is preferably performed after the incorporation of the below-mentioned active ingredient. In addition, in addition to the above-described components, for example, a corrosion inhibitor, a dye, an antioxidant, a pH adjuster, an antistatic agent, a stabilizer, or a wetting agent may be appropriately added to the base material as necessary. it can. The above-mentioned base material is displaced by the application of thermal energy to the dipole 12 existing inside the base material 11 as shown in FIG. The displacement of the dipoles 12 means that the dipoles 12 inside the base material 11 rotate or shift in phase. It can be said that the arrangement state of the dipoles 12 inside the base material 11 before the energy is applied as shown in FIG. 1 is in a stable state. However, as shown in Fig. 2, when the energy is applied, when the dipole 12 existing inside the base material is displaced, the base material 1

Each dipole 1 2 inside 1 will be placed in an unstable state, and each dipole 1

2 tries to return to the stable state shown in Figure 1. At this time, energy is consumed. It is thought that the specific heat effect of "difficult to warm but difficult to cool once heated" is caused by the displacement of the dipole inside the base material and the energy consumption by the restoring action of the dipole. When considering the mechanism of such energy consumption, it is understood that the amount of dipole moment inside the substrate 11 as shown in FIGS. 1 and 2 plays a large role. In other words, when the amount of the dipole moment inside the substrate 11 is large, the consumption of the energy (specific heat) of the substrate 11 increases. The amount of the dipole moment in the base material varies depending on the types of components constituting the base material described above. Even if the same base material components are used, the amount of dipole moment generated in the base material changes depending on the temperature when energy is applied. The amount of dipole moment also changes depending on the magnitude of the energy applied to the substrate. For this reason, it is desirable to appropriately select and use a base material component that gives the largest amount of dipole moment in consideration of the temperature, the magnitude of energy, and the like when applied as a high specific heat composition. However, when selecting the base material components, not only the amount of dipole moment in the base material, but also the handleability, formability, availability, etc., depending on the application and use form of the high specific heat composition. It is desirable to consider temperature performance (heat resistance and cold resistance), weather resistance, and price. An active ingredient that increases the amount of dipole moment in the base material is added to the base material. The active component is a component that dramatically increases the amount of dipole moment in the base material.The active component itself has a large dipole moment, or the active component itself has a small dipole moment. A component that can dramatically increase the amount of dipole moment in the base material by incorporating an active component. For example, the amount of the dipole moment generated in the base material 11 under the predetermined temperature conditions and the magnitude of the energy can be reduced by adding the active ingredient to the base material 11 under the same conditions as shown in FIG. That is, it will increase by a factor of two or ten. Along with this, it is thought that the energy consumption due to the dipole restoring action when the above-mentioned energy is added will increase drastically, and a high specific heat effect far beyond the prediction will be generated. Examples of active ingredients that induce such effects include N, N-dicyclohexylbenzothiazyl-2-sulfenamide (DCHBSA), 2-mercaptobide (MBTS), N-ci (CBS), and N-tert. BS), N-Oxyjec

When the high specific heat composition is applied to applications such as a circulating fluid for floor heating, a fluid for a heat exchanger, a refrigerant used in a home air conditioner, a building air conditioner, a large freezer, and the like (when the base material is a gas). It is desirable to select and use an active ingredient whose boiling point is close to that of the base material. The content of the above-mentioned active ingredient is preferably 0.1 to 100 parts by weight with respect to 100 parts by weight of the base material. When the content of the active ingredient is less than 0.1 part by weight, a drastic increase in specific heat due to the incorporation of the above active ingredient cannot be obtained. On the other hand, when the content of the active ingredient is more than 100 parts by weight, the effect of only the added amount cannot be obtained, and it becomes uneconomical. In this high specific heat composition, the use of water, glycols, or a mixture thereof, which has been subjected to an electrostatic field treatment, as the base material facilitates the dissolution of the active ingredient, and the active ingredient constitutes the base material. It is thought that the specific heat rise by the above-mentioned active ingredient progresses more effectively, and as a result, a higher level of high specific heat effect can be obtained. Next, the high specific heat composition according to claims 4 to 6 will be described. This high specific heat composition is based on water, glycols, or a mixture thereof, to which an active ingredient is blended, and which has been subjected to an electrostatic field treatment. This high specific heat composition is different from the above high specific heat composition according to claims 1 to 3 in that the base material is subjected to an electrostatic field treatment, whereas the entire composition is subjected to an electrostatic field treatment. The details of the composition and each component are omitted because they are only different. In this high specific heat composition, the base material and the active component are subjected to an electrostatic field treatment, and the active component is easily dissolved in the base material as in the high specific heat composition according to any one of claims 1 to 3; Can enter the molecular level of the base material, It is thought that the specific heat increase due to the minute progresses more effectively, and as a result, a higher level of high specific heat effect can be obtained.

The specific heat of the high specific heat composition of the example immediately rises from about 0.8 to 0.83 after the adjustment, does not immediately drop, and maintains a stable level at about 0.78. It was much higher than those of 1 and 2, and it was confirmed to have an excellent high specific heat effect.
