る。しかしながら。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to coolants. Conventionally, as a portable coolant, one is known in which water is added to a substance that absorbs heat when dissolved, such as ammonium nitrate, at the time of use. Further, salt containing crystal water may be used as a water source. however.
既存のものは何れも使用後液状になるため容器の破損時
などが問題となる。All existing products become liquid after use, which poses a problem when the container is damaged.
一方、結晶水から水を供給する場合は冷却速度や効率が
落ち充分に目的を達成することができなかった。On the other hand, when water is supplied from crystallized water, the cooling rate and efficiency decrease, and the purpose cannot be fully achieved.
本発明者は、これらの間通を解決すべく鋭意研究の結果

したものである。As a result of intensive research to solve these shortcomings, the present inventor succeeded in turning water into a gel as a water source, and using a water-absorbing porous silicic acid compound to turn it into a powder after use. This is what I did.
本発明にいう溶解時に吸熱する物質としては。Examples of substances that absorb heat during melting according to the present invention include:
塩化アンモニウム、硝酸アンモニウム、硫酸アンモニウ

が挙げられるが、経済性、危険性、冷却効果などから、
硝酸アンモニウム及び尿素の使用が好ましい。Ammonium chloride, ammonium nitrate, ammonium sulfate, ammonium bicarbonate, potassium chloride, potassium nitrate, sodium nitrate, sodium carbonate decahydrate, sodium arsenite, iron nitrate (■) nonahydrate, sodium tetraborate 1
Examples include crystals of 0 hydrate, sodium perborate tetrahydrate, sodium thiosulfate pentahydrate, diammonium phosphate, urea, etc., but due to economic efficiency, danger, cooling effect, etc.
Preference is given to using ammonium nitrate and urea.

フローライトＲである。Further, as the porous silicate compound referred to in the present invention, gyrolite type calcium silicate having a petal shape can be mentioned. This petal-shaped gyrolite type calcium silicate is manufactured by Tokuyama Soda and its trade name is Fluorite R.
更に水のゲル化に際しては、一般的に販売されている水
溶性ゲル化剤を用いることができる。Furthermore, when gelling water, commonly available water-soluble gelling agents can be used.

混合できるようにしたものが使用上便利である。The ratio of each substance used in the coolant of the present invention is preferably 50 to 500 parts, preferably 100 to 200 parts, of the endothermic substance per 200 parts of gelled water. The gelled water, the substance that absorbs heat when dissolved, and the porous silicic acid compound may be sealed in any container as long as it can be mixed during use. It is convenient to use a bag in which gelled water, an endothermic substance, and a porous silicic acid compound are placed separately so that they can be mixed at the time of use.
本発明にかかる冷却剤において水は、ゲル化しであるの

損時などの問題も解決できるのである。以下、実施例に
より詳細に説明する。Since the water in the coolant according to the present invention is in the form of a gel, when mixed with an endothermic substance, water is gradually released and the coolant exhibits the effect of being able to maintain a low temperature for a long period of time. In addition, after use, the coolant that has become a solution layer becomes a powder rather than being adsorbed by the porous silicic acid compound, so problems such as damage to the container can be solved. Hereinafter, it will be explained in detail using examples.
実施例１゜
室温２０℃において、重版のゲル化剤と水を重′量比で
１：１で混合撹拌しゲル化した水２００ｇに吸熱性物質

た。その結果を表１に示す、尚、本発明品はいずれも粉
末状態になった。Example 1゜At a room temperature of 20°C, a gelling agent for reprinting and water are mixed and stirred in a weight ratio of 1:1. To 200g of gelled water, an endothermic substance and a porous silicic acid compound are added with forced stirring and the temperature is increased. Measurements were taken to determine the lowest temperature and the time it took to reach +10°C. The results are shown in Table 1. All of the products of the present invention were in a powder state.
以上の結果、本発明品は優れた冷却効果と使用後の形態
を有することが判明した。As a result, it was found that the product of the present invention has an excellent cooling effect and a good shape after use.
以上that's all
