Inorganic hydrates such as hydrate, sodium thiosulfate pentahydrate, and sodium acetate trihydrate have a large coagulation characteristic of hydrates.
Because it has latent heat of fusion, its use as a heat storage material is being considered in various ways, and it is widely used in greenhouses for greenhouse horticulture and cultivation, home heating, chemical heat pumps, solar heat storage tanks, industrial waste heat recovery equipment, etc. It is being utilized.

The present invention aims to provide a heat storage material composition that can arbitrarily adjust its latent heat generation temperature and expand the field of latent heat utilization.

In addition, a water-absorbing polymer substance is added as a stabilizer for preventing phase separation, and the latent heat generation temperature is adjusted.
［作用］

非常に狭い範囲に特定されるため、用途は著しく制限さ
れる。[Function] In the present invention, sodium acetate trihydrate is used as the main material for heat storage, and sodium acetate trihydrate has a melting temperature of about 58°C and a solidification temperature of 56°C. As long as it is used alone, the latent heat utilization temperature is specified in a very narrow range of about 56 to 58°C, and its applications are severely limited.
そこで本発明では融点調節剤としてエチレングリコール
を使用し、その添加量によって融点を調整することによ
り潜熱利用分野の拡大を図っている。Therefore, in the present invention, ethylene glycol is used as a melting point regulator, and the melting point is adjusted by the amount added, thereby expanding the field of latent heat utilization.
ところで一般に結晶性無機質化合物の融点が融点降下剤
の添加によって降下することは古くから知られている。Incidentally, it has been known for a long time that the melting point of a crystalline inorganic compound is generally lowered by the addition of a melting point depressant.
しかしながら融点降下剤の添加による融点の降下量は比

実用性が失われる。そのため、こうした融点降下現象を
潜熱発生温度の調整に積極的に活用しようとする研究は
殆んど成功していない。However, the amount by which the melting point is lowered by the addition of the melting point depressant is relatively small, and if a large amount of the melting point depressant is added, the stability of the entire composition decreases and phase separation tends to occur, making it impractical as a heat storage material. Therefore, research that attempts to actively utilize such melting point depression phenomenon to adjust the latent heat generation temperature has hardly been successful.

完成した。However, when the present inventors conducted various studies on heat storage material compositions mainly composed of sodium acetate trihydrate, they found that: ■ When ethylene glycol is used as a melting point adjuster,
The melting point can be arbitrarily adjusted within a wide range depending on the amount added. ■Additionally, if ethylene glycol is added as a melting point adjuster, the separation stability of the entire heat storage material deteriorates, making it difficult to put it into practical use. Similar to the case, we confirmed the fact that when a water-absorbing polymeric substance was added as a third component, the separation stability was significantly improved, and excellent separation stability was obtained that was sufficient to withstand repeated use. Based on these facts, the present invention was completed.

するものである。That is, in the present invention, by selecting sodium acetate trihydrate as the main material and blending it with an appropriate amount of ethylene glycol as a melting point regulator, it is possible to secure a latent heat generation temperature according to the use and purpose, and to adjust the composition. A water-absorbing polymer substance is blended as a stabilizer to prevent phase separation of the product as a whole and maintain a stable latent heat generation temperature even after repeated use.

方多過ぎる場合は主材の絶対量が不足気味となって蓄熱
容量が少なくなるので好ましくない。As shown in Figure 1 below, there is a difference of 1 between the blending amount of ethylene glycol and the melting temperature for sodium acetate trihydrate.
There is a sub-functional relationship, and by adjusting the content of ethylene glycol, the melting temperature can be freely controlled from approximately 55°C to 30-35°C, achieving the optimal latent heat depending on the application and purpose. It is possible to obtain a heat storage material composition having a generation temperature. In addition, the water-absorbing polymeric substance used as a separation stabilizer has excellent affinity for both sodium acetate trihydrate and ethylene glycol, and in combination with the swelling and thickening effect due to water absorption, it facilitates the separation of the above mixture. It is an essential component to provide a stable heat storage material composition, and includes synthetic polymers such as polyvinyl alcohol, sodium polyacrylate, polyacrylamide, and carboxymethyl cellulose, and natural polymers such as starch and sodium alginate. substance is used. The composition and amount of these water-absorbing polymeric substances are not particularly limited, but it is preferably 0.5 to 10% by weight, more preferably 2 to 6% by weight based on the total of sodium acetate trihydrate and ethylene glycol. If it is less than the above lower limit, the effect of improving separation stability will not be sufficiently effectively exhibited, while if it is too large, the absolute amount of the main material will be insufficient and the heat storage capacity will decrease, which is not preferable.

かった。As is clear from Table 1 and Figure 1, in the heat storage material composition based on sodium acetate trihydrate, there is a linear function between the ethylene glycol content and the melting temperature. It can be seen that the melting temperature of the heat storage material composition can be freely adjusted within a wide range by changing the ethylene glycol content. Furthermore, the separation stability of the obtained heat storage material compositions was extremely good, and no phase separation was observed even after repeating melting and solidification 200 times. Further, since each of these heat storage material compositions contained an appropriate amount of a crystal nucleating agent, no supercooling phenomenon was observed.
