〔産業上の利用分野〕
本発明は蓄熱材に関し、更に詳しくはパラフィン類を主
成分として用いた蓄熱材に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a heat storage material, and more particularly to a heat storage material using paraffins as a main component.
従来蓄熱材はその原理から物質の顕熱を利用するもの、
物質の相変化潜熱を利用するもの、物質の化学反応熱を
利用するもの等がある。現在実用的な面より物質の相変
化潜熱を利用する蓄熱材が注目を集めており、蓄熱式空
調機器、蓄熱式建材、各種保温器具や装置等に利用され
つつある。Conventional heat storage materials utilize the sensible heat of substances based on their principle.
There are those that utilize the latent heat of phase change of substances, and those that utilize the heat of chemical reaction of substances. Currently, heat storage materials that utilize the phase change latent heat of substances are attracting attention from a practical standpoint, and are being used in heat storage type air conditioners, heat storage type building materials, and various heat retention appliances and devices.
この相変化潜熱を利用する蓄熱材の一つとしてパラフィ
ン等の有機物質を用いた所謂有機蓄熱材がある。この有
機蓄熱材は使用中に過冷却、相分離等の難点が少なく、
長期寿命に優れているので従来から注目されている。As one type of heat storage material that utilizes this phase change latent heat, there is a so-called organic heat storage material that uses an organic substance such as paraffin. This organic heat storage material has fewer problems such as supercooling and phase separation during use.
It has long been attracting attention because of its long lifespan.
元来、潜熱型蓄熱材は無機系、有機系を含め固体から液
体への相変化時に蓄熱し、液体から固体への相変化時に
放熱する。このためこれ等潜熱型蓄熱材を利用するため
には液化時に流動して漏れないような形態を保つような
配慮が要求さる。このための密閉容器や袋に収納する方
法では、充分なる強度を有する容器等を使用すればコス
トが高く実用的ではなく、また簡易的なものにすれば容
易に破損して液が漏れたり溢れたりする恐れがあり長期
間使用する点では問題が生じる。Originally, latent heat type heat storage materials, including inorganic and organic types, store heat when the phase changes from solid to liquid, and radiate heat when the phase changes from liquid to solid. Therefore, in order to utilize these latent heat type heat storage materials, consideration must be given to maintaining a form that does not flow and leak when liquefied. The method of storing the liquid in an airtight container or bag is expensive and impractical if you use a container with sufficient strength, and if you use a simple container, it will easily break and cause the liquid to leak or overflow. This poses a problem when used for a long period of time.
従って容器に収納する手段に代わって（イ）多孔質物質
内に収納する、（ロ）マイクロカプセル化する等の方法
が提案され、またこれ等を組合わせた方法が使用されつ
つある。更にはまた（ハ）ポリオレフィン、通常は架橋
ポリオレフィンに収納させてカプセル中に閉し込める方
法も提案されている。Therefore, instead of storing in a container, methods such as (a) storing in a porous material, and (b) microencapsulation have been proposed, and methods that combine these methods are being used. Furthermore, a method has also been proposed in which (c) the polyolefin is housed in a polyolefin, usually a crosslinked polyolefin, and encapsulated in a capsule.
しかしながら上記各方法によってもパラフィン等の滲み
出しが完全には防止出来ずに大きな問題となっており、
その他製造上の工程が複雑でコスト高となったり、単位
体積当たりの蓄熱材の６有量が減少する等の問題が生じ
る。更に上記〈口〉のマイクロカプセル化する方法では
カプセル間に空間が生じ、この空間の存在により単位体
積当たりの蓄熱性能が低下する。However, even with the above methods, the oozing of paraffin, etc. cannot be completely prevented and has become a major problem.
Other problems arise, such as the manufacturing process being complicated and resulting in high costs, and the amount of heat storage material per unit volume being reduced. Furthermore, in the microencapsulation method described above, spaces are created between the capsules, and the existence of these spaces reduces the heat storage performance per unit volume.
またその他の従来方法として結晶性ポリエチレン等の結
晶状ポリオレフィンに練り込む方法も知られているが、
取扱い上の難点がある。たとえば硬くて取扱いが困難で
あったり、通常の取扱い中に破損したりする。更に高温
でパラフィン等が相分離して滲み出す難点も生じ、これ
を防止するためには容器を強固なものとする必要があり
実用的ではない。Another known conventional method is to knead it into crystalline polyolefin such as crystalline polyethylene.
There are some difficulties in handling. For example, they may be hard and difficult to handle, or they may break during normal handling. Furthermore, there is the problem that paraffin and the like phase separate and ooze out at high temperatures, and in order to prevent this, it is necessary to make the container strong, which is not practical.
一般に蓄熱材は、限られた空間に設置されることが多く
、特に蓄熱材の好ましい用途である蓄熱式床暖房装置の
場合等ではその設置空間は極めて限定され、単位体積当
たりの蓄熱量が少しでも大きいことが強く要望されてい
る。In general, heat storage materials are often installed in limited spaces, and especially in the case of thermal storage floor heating systems, which are the preferred use for heat storage materials, the installation space is extremely limited, and the amount of heat storage per unit volume is small. But there is a strong demand for something bigger.

Furthermore, by crosslinking the hydrocarbon rubber, the heat storage material exhibits extremely excellent performance without melting, dripping, phase separation, bleeding, etc. even when the T of paraffins is 18 or higher.
