The present invention relates to a heat storage agent composition containing calcium chloride hexahydrate. Calcium chloride hexahydrate has a melting point of 29℃ and a latent heat.
It has a content of 41 cal/g and is widely used as a heat storage agent for waste heat recovery, solar heat storage, heating, etc., but it is used for heating greenhouses for forced cultivation because a melting point of 15 to 30 degrees Celsius is required. However, the range of use of calcium chloride hexahydrate alone was limited. Calcium chloride hexahydrate also has drawbacks such as supercooling and a decrease in latent heat when used repeatedly. To address these drawbacks, methods of adding strontium halide (Japanese Patent Publication No. 56-9959), adding nickel chloride (Japanese Patent Publication No. 56-9960), and adjusting the amount of water to a certain level (Japanese Patent Publication No. 56-9960) have been proposed. 57
-38879) have been proposed, but
Both are insufficient. Moreover, in these improved methods, the melting point was 25 to 29°C, and the usable range remained limited. The present invention was made to improve the above-mentioned conventional drawbacks, and by blending a specific polyoxyethylene ether into a heat storage material whose main component is calcium chloride hexahydrate, the melting point can be lowered. Ten
The purpose of the present invention is to provide a heat storage agent composition that can be adjusted to any temperature within the range of ~30°C, prevents overcooling, and does not lose latent heat even after repeated use. The present invention is a heat storage agent composition characterized by containing 50 to 95% by weight of a heat storage material mainly composed of calcium chloride hexahydrate and 5 to 50% by weight of a compound represented by the following general formula []. . (However, R is a residue of a compound having 3 to 24 active hydrogen atoms, n is the average number of added moles of ethylene oxide and is 1 to 20, a is a positive integer, b is 0 or a positive integer, and a+b is the above-mentioned (The number corresponds to active hydrogen.) A heat storage substance whose main component is calcium chloride hexahydrate is calcium chloride hexahydrate ( CaCl2 .
6H 2 O) as a sole component, or calcium chloride hexahydrate as the main component and other substances such as barium chloride, nickel chloride, strontium chloride, etc. in an amount of 10% by weight or less, and have heat storage properties. It shows. In the general formula [], 3 to 24 where R is a residue
Compounds with active hydrogen include glycerin, diglycerin, polyglycerin, trimethylolpropane, erythritol, pentaerythritol, dipentaerythritol, polypentaerythritol, sorbitol, sorbitan, sorbide, condensates of glycerin and sorbitol,
Examples include compounds having a hydroxyl group or an amino group, such as mannose, glucose, xylose, fructose, sucrose, trehalose, ammonia, ethylenediamine, triethylenetetramine, and tetraethylenepentane. The compound of the general formula [] can be produced by adding 20 moles or less of ethylene oxide per active hydrogen to the above-mentioned compound having R as a residue. In this case, ethylene oxide may be added to all active hydrogens, but it is not necessarily necessary to add ethylene oxide to all active hydrogens, and there may be hydroxyl groups, amino groups, etc. to which ethylene oxide is not added. In the general formula [], the active hydrogen of the compound having R as a residue is limited to 3 to 24 because if it is 2 or less, it cannot be mixed with a heat storage material whose main component is calcium chloride hexahydrate. This is because if it exceeds 25, the viscosity becomes high and handling becomes difficult. The alkylene oxide to be added is limited to ethylene oxide,
In addition, the number of moles added is limited to the above range when other alkylene oxides are used, or when the number of moles added is outside the range, the heat storage material whose main component is calcium chloride hexahydrate is used. This is because it cannot be mixed with The heat storage agent composition of the present invention contains 50 to 95% by weight of a heat storage material mainly composed of calcium chloride hexahydrate and 5 to 50% by weight of a compound of general formula [], both of which are in a mixed state. used in The melting point of the heat storage agent composition can be adjusted by the blending ratio of the two, and the melting point decreases as the blending ratio of the compound of general formula [] increases. In addition to the above two components, other third components may be added as necessary.
It is permissible to add other ingredients. The heat storage substance containing calcium chloride hexahydrate as a main component may contain substances other than those listed above. Moreover, one compound of the general formula [] may be used alone, but several kinds of compounds depending on the difference in R, n, a, and b may be used in a mixed state. In addition to the above-mentioned uses, the heat storage agent composition of the present invention can be used for other uses that suit the respective melting points by adjusting the melting point and the like. As explained above, according to the present invention, a specific polyoxyethylene ether is blended into a heat storage material mainly composed of calcium chloride hexahydrate, so that the melting point can be increased from 10 to 30°C. In addition to being able to adjust the temperature within the range of , it also has the advantage of preventing overcooling, preventing the latent heat from decreasing even after repeated use, and allowing stable use for other purposes. Next, examples of the present invention will be described. In addition,
All percentages in each example indicate weight percent. Example 1 A heat storage agent composition consisting of calcium chloride hexahydrate and the compounds shown in Table 1 was prepared, and the melting point, latent heat, and presence or absence of supercooling were measured. Table 1 shows the results.
Shown below. In Table 1, EO indicates an ethylene oxide adduct, and the number added in front of it indicates the average number of moles added. Further, the number in parentheses after polyglycerin indicates the average degree of polymerization of polyglycerin. The content of calcium chloride hexahydrate is the remainder of the content in Table 1.

The melting point of these compositions was 18° C. for the composition containing compound No. 5, and 22° C. for the composition containing compound No. 13, and the latent heat was 35 cal/g for both compositions. When these compositions were subjected to a test of repeated temperature changes from 0 to 50°C, they were stable even after 500 repeated temperature changes from 0 to 50°C, and both the melting point and latent heat showed the same values as at the time of preparation. No change was observed, and no supercooling was observed. In contrast, a comparative product consisting of 96.0% calcium chloride hexahydrate and 4.0% barium chloride had a melting point of 29°C and a latent heat of 41 cal/g at the time of preparation.
In a test under the same conditions, the latent heat began to decrease after the 100th test, and reached 0 after the 160th test. Also calcium chloride hexahydrate 86.4%, barium chloride 3.6% and polyethylene glycol (average molecular weight 400)
The comparative product consisting of 10.0% had a melting point of 27℃ at the time of preparation.
The latent heat was 35 cal/g, but the melting point was 29 at the 35th time.
℃, the latent heat starts to decrease from the 100th time, and 160
The latent heat became 0. From the above results, compared to the comparative product, the product of the present invention has
It can be seen that the melting point can be adjusted, both the melting point and latent heat are stable, and supercooling does not occur.
