Description
【０００１】 ［産業上の利用分野］ この考案は、可撓性をもった断熱材に関するものである。[Field of Industrial Application] The present invention relates to a heat insulating material having flexibility.
【０００２】 ［従来の技術］ 従来、合成樹脂の内部に、連続または不連続な気泡を分散させた発泡樹脂の 板状体や特定形状に成型した塊状体を断熱材として用いることは広く行はれ、 比較的満足な断熱効果が得られている。 しかし、被断熱体が形状の一定しないものである場合は、断熱材の形状を被 断熱体の一定しない形状に追従させる必要があるので、粒状の発泡樹脂を用い ることによって可撓性、流動性をもたせ対応しているが、その断熱効果は十分 でなく、またその流動性を適量に制御することの困難があった。[Prior Art] Conventionally, it has been widely practiced to use a plate-like body of a foamed resin in which continuous or discontinuous bubbles are dispersed in a synthetic resin or a lump molded into a specific shape as a heat insulating material. And a relatively satisfactory heat insulation effect is obtained. However, if the shape of the heat insulating material is not constant, it is necessary to make the shape of the heat insulating material conform to the shape of the heat insulating material. However, the heat insulation effect was not sufficient, and it was difficult to control the fluidity in an appropriate amount.
【０００３】 ［考案が解決しようとする課題点］ この考案は、形状変化する被断熱材に合せた形状をとり、しかも断熱効果の 高い可撓性をもった断熱材を提供するものである。[Problems to be Solved by the Invention] The present invention provides a flexible heat insulating material having a shape adapted to a material to be heat-insulated whose shape is changed and having a high heat insulating effect.
【０００４】 ［課題を解決するための手段］ 課題の解決手段を図面を用いて説明する。 この考案は、粒状発泡樹脂１と高吸水樹脂２の混合体３と、これを包括する 可撓性をもった袋体４で構成される。 粒状発泡樹脂１は、ポリエチレン、ポリスチレン等の合成樹脂内部に、連続 または不連続な多数の気泡を含有する発泡樹脂と呼ばれるものの粒状体である 。その内部気泡の含有比率（発泡倍率）は混合体３の圧縮強度に強く影響をお よぼす。粒状体の圧縮強度と断熱性能という相反する２性能を共に満足させる ために、通常発泡倍率を５〜３０％の範囲に定めるのが望ましい。 また粒状発泡樹脂１の粒径は、混合する高吸水樹脂２と均一に混和分散させ るために、それそれの粒径が大きすぎたり、粒径差が多すぎるものは適当でな い。粒状発泡樹脂１、高吸水樹脂２それぞれの粒径は、共に１０ミリメートル を越えないものが良い。 高吸水樹脂２は、自重の少なくも３０倍以上の水分を吸水する粒状・粉状の 樹脂で、アクリル酸ナトリウム架橋体・アクリル酸ビニールアルコール共重合 体・ポリエチレンオキサイト変成物・親水性ポリオレフィン等の樹脂がある。 可撓性をもった袋体４は、織物・編物・不織布・紙など柔軟で可撓性があり 混合体３がその目合いから漏洩散逸することのない程度に密であり、しかも袋 体の内外にある水分を容易に透過させることのできる面状体で構成され、混合 体３を包括封じ込めている閉じた袋体である。 袋体の素材は、断熱材の用途によって、セルロース・羊毛繊維のように親水 性を有し、高吸水樹脂２が吸水膨潤している状態のとき同時に湿潤し、袋体の 表面から水分が発散しやすいものと、ポリオレフィン・ポリエステル繊維のよ うに疎水性で表面が湿潤しにくいものを使い分けることができる。[Means for Solving the Problem] Means for solving the problem will be described with reference to the drawings. This invention comprises a mixture 3 of granular foamed resin 1 and highly water-absorbent resin 2, and a flexible bag body 4 including the mixture. The granular foamed resin 1 is a granular body of what is called a foamed resin containing a large number of continuous or discontinuous bubbles inside a synthetic resin such as polyethylene or polystyrene. The content ratio of the internal bubbles (foaming ratio) has a strong influence on the compressive strength of the mixture 3. In order to satisfy the two contradictory performances of the compression strength and the heat insulation performance of the granules, it is usually desirable to set the expansion ratio within the range of 5 to 30%. Further, the particle size of the granular foamed resin 1 is not appropriate because the particle size thereof is too large or the particle size difference is too large in order to uniformly mix and disperse it with the superabsorbent resin 2 to be mixed. The particle size of each of the granular foamed resin 1 and the highly water-absorbent resin 2 should not exceed 10 mm. Super absorbent resin 2 is a granular / powdered resin that absorbs at least 30 times more water than its own weight, such as sodium acrylate cross-linked product / vinyl acrylate vinyl alcohol copolymer / polyethylene oxide modified product / hydrophilic polyolefin. There is a resin. The flexible bag body 4 is soft and flexible such as woven fabric, knitted fabric, non-woven fabric, paper, etc., and is dense enough that the mixture 3 does not leak and dissipate due to its mesh. It is a closed bag body that is composed of a planar body that allows water inside and outside to easily permeate, and encloses the mixture 3 inclusive. The material of the bag has hydrophilicity such as cellulose / wool fiber depending on the use of the heat insulating material, and when the super absorbent resin 2 absorbs water and swells, the bag is wet at the same time, and the moisture wicks from the bag surface. It is possible to use one that is easy to do and one that is hydrophobic and does not easily wet the surface, such as polyolefin / polyester fiber.
【０００５】 ［作用］ この考案を構成する混合体３において、粒状発泡樹脂１は、その内在する気 泡によって、単体樹脂より断熱効果が高いことはもとよりである。高吸水樹脂 ２は、水分を含浸させることにより膨潤して発泡樹脂１との間隙を埋める。こ のために混合体３の過度の流動を抑制し、混合体３の形状をその時の状態に保 つ。また、吸水した高吸水樹脂自体の熱容量の大きさによって、断熱効果が高 まる。 更に、本考案の断熱材を高温下における遮熱体として使用する場合は、袋体 ４の表面から蒸散する水分の気化熱によっても温度上昇を抑制する作用がある 。特に、混合体３の中に分布している粒状発泡樹脂１のために、高吸水樹脂２ の層は比較的薄い層になっており、高吸水樹脂２と、粒状発泡樹脂１との境界 面、袋体４との境界面の面積和は大きく、境界面からの水分蒸散を助長する効 果がある。また、混合体３を包括している袋体４として、セルロース繊維等の 親水性繊維を用いると、袋体４の表面が常に湿潤しており、水分が蒸散しやす い状態を作っている。 このように、この考案は、粒状発泡樹脂１と高吸水樹脂２との混合と袋体の 選択によって、断熱効果に相乗効果をもたらす。[Operation] In the mixture 3 constituting the present invention, it is a matter of course that the granular foamed resin 1 has a higher heat insulating effect than the single resin due to the bubbles contained therein. The highly water-absorbent resin 2 swells when impregnated with water and fills the gap with the foamed resin 1. Therefore, the excessive flow of the mixture 3 is suppressed, and the shape of the mixture 3 is maintained in the state at that time. In addition, the heat insulation effect is enhanced by the amount of heat capacity of the highly absorbent resin itself that has absorbed water. Further, when the heat insulating material of the present invention is used as a heat shield under high temperature, the heat of vaporization of water evaporated from the surface of the bag 4 also has an effect of suppressing the temperature rise. In particular, due to the granular foamed resin 1 distributed in the mixture 3, the layer of the superabsorbent resin 2 is a relatively thin layer, and the boundary surface between the superabsorbent resin 2 and the granular foamed resin 1 is The sum of the area of the boundary surface with the bag body 4 is large, and it has the effect of promoting water evaporation from the boundary surface. Further, when hydrophilic fibers such as cellulose fibers are used as the bag body 4 including the mixture 3, the surface of the bag body 4 is always wet, and a state in which water easily evaporates is created. Thus, the present invention brings about a synergistic effect on the heat insulating effect by mixing the granular foamed resin 1 and the highly water-absorbent resin 2 and selecting the bag body.
【０００６】 ［実施例］ 幅９０センチメートル、長さ１２０センチメートルの２層の綿織物の間に、 発泡スチレン粒状体１００グラムと、高吸水樹脂ポリアクリル酸ナトリウム２ ０グラムを均等に分散するように混合したものを配し、周辺を縫製によって固 定してマット状にする。このマット状物を、約１時間水中に浸漬して十分に吸 水させたものを乗用車の屋根の下に吸盤によって取り付けると、その断熱効果 によって、室内が異常に昇温することを抑制することができる。[Example] Between two layers of cotton fabric having a width of 90 cm and a length of 120 cm, 100 g of expanded styrene granules and 20 g of superabsorbent resin sodium polyacrylate were evenly dispersed. Place the mixture in and sew the area around it to form a mat. If this mat-like material is immersed in water for about 1 hour to allow it to absorb sufficient water, it will be installed under the roof of a passenger car with a suction cup to prevent the temperature inside the room from rising abnormally.
