【発明の詳細な説明】
産業上の利用分野
本発明は、潜熱を利用した蓄熱材料に闇する従来の技術
Ｆａ熱を利用した＄８物質に関するものは数多く提案さ

態ではなかった。[Detailed Description of the Invention] Industrial Field of Application The present invention relates to heat storage materials that utilize latent heat.Conventional technology There have been many proposals regarding $8 materials that utilize Fa heat, but all of the proposals have been made. They were not always fit for use.
最大の課題が然サイクルに対応した品質の安定性と経済
性にあり、解決法として種々の潜熱物質毎に安定剤が提
案されている。The biggest challenge lies in quality stability and economy in response to thermal cycles, and stabilizers have been proposed for various latent heat substances as solutions.
酢酸ナトリウム３水塩は蓄熱材料として熱容量、応答性
に優れ融解潜熱を結晶化の過程で放熱する。Sodium acetate trihydrate has excellent heat capacity and responsiveness as a heat storage material, and radiates latent heat of fusion during the crystallization process.
一般的に持水塩を有する蓄熱物質は融解すると低粘性の
液状を呈するが特に、酢酸ナトリウム水溶液は傾向が顕
著である。Generally, a heat storage material having a hydrated salt exhibits a low viscosity liquid state when melted, and this tendency is particularly noticeable in an aqueous solution of sodium acetate.
その結果相分離、過冷却現象が特に大きく、これ等の現
象の防止を無視して潜熱利用の蓄熱材料として使用出来
なかった。As a result, phase separation and supercooling phenomena were particularly severe, and prevention of these phenomena was ignored and the material could not be used as a heat storage material for utilizing latent heat.
使用される安定材が多糖類であったり、オレフィン系、
多価アルコール系、無機土類等粘土４！ｒ物等が従来知
られている。The stabilizers used are polysaccharides, olefins,
Polyhydric alcohol-based, inorganic earth, etc. clay 4! R products and the like are conventionally known.

発明が解決しようとする問題点
上記発明になるものは無機粘土質物を除き、有機物質で
あるために加熱サイクルの過程で融解温度域のコントロ
ールが不可欠であった。Problems to be Solved by the Invention Since the materials of the invention described above are organic materials, excluding inorganic clay materials, it is essential to control the melting temperature range during the heating cycle process.
例えば酢酸ナトリウム系蓄熱材の融解点は５８℃である
／＋９使用する安定剤が規定温度以上特に高温に達する
と熱的影響を受ける結果、物性が変化し、安定材の機能
低下を起こし、その結果、結晶化が起こらない等の欠点
があった。For example, the melting point of sodium acetate-based heat storage material is 58℃/+9 When the stabilizer used reaches a particularly high temperature above the specified temperature, it is thermally affected, resulting in changes in physical properties and a decline in the function of the stabilizer. As a result, there were drawbacks such as no crystallization.
又、無機粘土質物について、例えば特許公ｌ＃ｌ６１−
１１９８６号でカオリン、ケイソウ土、ベントナイトが
示されている。Regarding inorganic clay materials, for example, Patent Publication #161-
No. 11986 shows kaolin, diatomaceous earth, and bentonite.
上記記載の粘土類の成分機能は該品と構造上。The component functions of the clays described above are based on the structure of the product.
異なる物性であり、可塑性を有する粘性資質の利用を計

融状層下で高温に置かれると凝集して安定したウエット
ボリームや粘性を無くし安定剤の機能を消失する事が知
られており、ケイソウ土、カオリンは可塑性に優れるが
、信置性、吸着性に欠けるので添加量を必要とした。Bentonite has different physical properties, and aims to utilize its viscous qualities with plasticity.The proposed bentonite has a large ion exchange capacity due to its properties, so when used as a stabilizer, it becomes unstable when placed at high temperatures under a eutectic layer. It is known that it aggregates and loses stable wet volume and viscosity, and loses its function as a stabilizer.Diatomaceous earth and kaolin have excellent plasticity, but lack reliability and adsorption properties, so it was necessary to add a large amount. .
相分離防止に使用される他の有機質物増粘材は限られた
条件下で特定の化合物の吸着性や増粘性に優れるものが
多く知られている。Many other organic thickeners used to prevent phase separation are known to have excellent adsorption and thickening properties for specific compounds under limited conditions.
−殻内に、イオン交換能が大きい物質が多く、塩基性や
アルカリ性質物と共融すると、吸＠能力や活性度が極度
に低−［し、凝固する傾向が強く、これらの機能を補う
ために各材料資質の特徴に応じた強化安定材を添加し複
合的に目的を達成する方法が取られている。-There are many substances with high ion-exchange ability in the shell, and when eutectic with basic or alkaline substances, the absorption capacity and activity are extremely low. For this purpose, a method is used to achieve the objective in a composite manner by adding reinforcing and stabilizing materials according to the characteristics of each material quality.
しかし、混合比率に上り共融構造が変化しやすく、加工
行程に於ける品質の安定管理面やコスト上、問題を残し
ていた。However, as the mixing ratio increases, the eutectic structure tends to change, leaving problems in terms of stable quality control and cost during the processing process.
問題を解決する為の手段
本発明はこれまで提案されている有機質物や無機質物安
定材の熱的物性変化を防止するには加熱コントロールが
品質変化を防止しうる最良の解決策であった欠点に鑑み

熱材を提供することを目的とするものであり、そこで、
本発明者はこれらの欠点のない潜熱蓄熱材料用の相分離

返しても劣化せず、担持体として資質と機能の不変性を
満たし、特に耐熱性を発揮し、且つ潜ｐＡＭ熱材料の保
有熱延に影響を与えない資質を有する事にあった。Means for Solving the Problem The present invention has the disadvantage that heating control was the best solution to prevent changes in the thermal properties of organic and inorganic stabilizers that have been proposed so far. In view of this, we have created a reliable and highly economical M with a II quality control and durability for long-term use.
The purpose is to provide a thermal material, and therefore,
As a result of various studies on stable materials for preventing phase separation for latent heat storage materials that do not have these drawbacks, the present inventors found that they do not deteriorate even after repeated heat storage and heat dissipation, satisfy the constancy of qualities and functions as a carrier, and are particularly heat resistant. It has the property of exhibiting high properties and not affecting the hot rolling properties of the latent pAM thermal material.
その要旨は繊維形状のセピオライトを成因とした繊維状
結晶構造セラミックスの資質に注目し前記記載の蓄熱材
料に一定量混ぜて劣化の防止を施した蓄熱材とした事に
ある。The gist of this is to focus on the qualities of fibrous crystalline ceramics made from fibrous sepiolite, and to create a heat storage material that is prevented from deteriorating by mixing a certain amount with the heat storage material described above.
即ち、以上のように構成することで、作製された酢酸ナ
トリウム系蓄熱材は長期間、ＪＰ１％〜放熱の行程で高
温の経返し使用を行っても蓄熱能力の低下や、相分離は
殆ど発生せず、所期の目的を達成出来たのである。In other words, with the above configuration, the fabricated sodium acetate heat storage material will hardly experience any decrease in heat storage capacity or phase separation even if it is repeatedly used at high temperatures in the heat dissipation process from JP1% to JP1% for a long period of time. Instead, they were able to achieve their intended purpose.
従来知られている高分子、例えばポリビニールアルコー
ルでは相分離Ｎ熱材に増粘安定材として単独で使用出来
ず、予めアセトン等で処理するか、混合しなければ単独
では１１集して使用出来なかったのみならず、耐熱性に
欠ける為、融解点より高温で蓄熱〜放熱を経返し加農す
ると分子の劣化を生じ、最後は分解して、Ｉｆｔａｎ再
生不能となっていた。Conventionally known polymers, such as polyvinyl alcohol, cannot be used alone as a thickening stabilizer in phase-separated N-thermal materials, and cannot be used alone in 11 groups unless they are treated with acetone etc. in advance or mixed. Not only was it not found, but it also lacked heat resistance, so if it was repeatedly processed through heat storage and heat release at temperatures higher than its melting point, the molecules deteriorated and eventually decomposed, making it impossible to regenerate Iftan.
本発明ではセピオライト繊維結晶物の構造体がゼオライ
トに見られる吸着性、ペンナイト特性に見られる信置性
、カオリン特性に代表される可塑性を兼備えている事に
着目した。The present invention focused on the fact that the sepiolite fiber crystal structure has adsorption properties found in zeolite, reliability seen in pennite properties, and plasticity typified by kaolin properties.
本該晶に採用したセピオライトの構造はｓａｇｙ＆ａｒ

30) Published as the structural formula of (OH)4-8142OJ, ¥tm is # made by stacking talc (talcum) alternately.
It has been clarified by high-resolution electronic 311I microscopic analysis that the fiber has an I structure, and that there are m number of tunnel-like pores with a diameter of 5.6 x 1,0 angstroms between the fibers.
このトンネルの、特異な吸着効果が保持力を発揮し、担
持体として安定材の働きをする。The unique adsorption effect of this tunnel exerts a holding power and acts as a support and stabilizer.
酢酸ナトリウム系蓄熱材は液状に融解するとアルカリ性
となるが、従来の増粘安定材と比軸において、セピオラ
イトは溶液中でのウェットボリューム、粘性効果が経時
変化においても一定値で安定して使用する事とができな
。Sodium acetate-based heat storage materials become alkaline when melted into liquid form, but when compared to conventional thickening and stabilizing materials, sepiolite's wet volume in solution and viscosity effects remain constant even over time and can be used stably. I can't do anything.
該＃熱材に採用したセピオライトは従来使用されている
多Ｍ類やオレフィン系、多価アルコール系、に見られる

得るセラミラス構造体のため、加熱による変質破壊がな
く、分離する事もない。The sepiolite used in this #thermal material has a molar effect due to molecular inclusion found in conventionally used poly-M, olefin-based, and polyhydric alcohol-based materials, and has a pore matrix that is different from the I structure of clays. Because it is a ceramilas structure that can selectively adsorb and strongly retain sodium acetate salt solution stably inside the matrix, it does not undergo deterioration or destruction due to heating and does not separate.
これ等の構造体が相分離を防止し、熱サイクルによる該
晶の物性を安定させている。These structures prevent phase separation and stabilize the physical properties of the crystal due to thermal cycles.
よって該晶添加の酢酸ナトリウムは、熱的に安定な蓄熱
材として長期間繰返しの使用にたえる蓄熱材とすること
ができる。Therefore, the crystal-added sodium acetate can be used as a thermally stable heat storage material that can be used repeatedly over a long period of time.

Although the hydrate crystals were completely melted, heating was continued and when the temperature of the sodium acetate solution reached 90°C, the temperature of the sodium acetate was cooled to 15°C using cooling water and a supercooled layer. The mixture was placed in a constant temperature bath kept at 15℃, and left at a constant temperature for 1 hour to create a two-layer structured environment caused by the difference in density of each mixed component.Then, the trigger was activated to supercool the mixture. We repeated the cycle of heating, cooling, and heat dissipation twice a day during the liquidation to crystallization process for three months, but until the end of the test period, no changes were observed in the reaction response of the physical properties. INZEN~ Perfectly fulfilled the heat dissipation cycle function.
