Description
本考案は、建物の外壁面、室内の内壁面等に断熱層を形成する用途に使用される建材に関するものである。 The present invention relates to a building material used for forming a heat insulating layer on an outer wall surface of a building, an inner wall surface of a room, or the like.
建物の外壁面、室内の内壁面等に断熱層等に用いられる断熱材は、ＪＩＳ規格として熱伝導率が０．１３より小さいことが条件となっており、これを満足するものが種々知られている。これらについては、ブロック形状になっているため、建物の外壁面、室内の壁面等に形成するのは困難であり、特に入り組んだ凹凸状の面に断熱材の層を設けることは困難であった。これに対して、壁面等に塗布の可能な断熱材であれば望ましい。 Insulation materials used for the heat insulation layer, etc., on the outer wall surface of the building, the inner wall surface of the room, etc. are required to have a thermal conductivity of less than 0.13 according to JIS standards, and various materials satisfying this condition are known. ing. About these, since it is a block shape, it was difficult to form on the outer wall surface of a building, the wall surface of a room, etc., and it was difficult to provide the layer of a heat insulating material especially on the complicated uneven surface . On the other hand, a heat insulating material that can be applied to a wall surface or the like is desirable.
また、最近の生産工場やインテリジェントビルは、作業環境の温度、湿度の管理に力を入れている所が多くなり、アメニティー空間の実現が重要なテーマとなっている。とりわけ、湿度環境に関しては、静電気発生と密接な関係があり、生産工場においては、生産性、品質の向上のみならず、安全対策面でも極めて重要な因子となっている。また、一般コマーシャルビルに於ても、各種のコンピューターや電子機器、計器類が、静電気を含めた放電等の、電磁波ノイズや不要電流等が原因となり、各種の誤作動を起す障害が生じている。この様な静電気や電磁波環境に対し、建造物の十分な帯電防止施設や、シールドを行うための複雑な設計と施工が必要とされ、この為のコスト高が大きな問題となっている。 In recent production factories and intelligent buildings, there are many places that focus on the management of the temperature and humidity of the work environment, and the realization of an amenity space has become an important theme. In particular, the humidity environment has a close relationship with the generation of static electricity, and is an extremely important factor in terms of safety measures as well as improving productivity and quality in production factories. Also in general commercial buildings, various computers, electronic devices, and instruments have various malfunctions due to electromagnetic noise and unnecessary currents such as discharge including static electricity. . For such static electricity and electromagnetic wave environments, sufficient antistatic facilities for buildings and complicated design and construction for shielding are required, and the high cost for this is a big problem.
さらに、メッキ工場や軽金属表面処理事業所から排出される廃液などは、多種多様の有用な金属成分を含んでいるにも拘らず、これらの廃液を処理して生成するスラッジは埋め立てに処分されるか若しくは海洋投棄などで処分されていることが多い。また、この廃液処理に際しては、廃液の脱水、乾燥処理のみならず、焼成やコンクリート固化処理などを行って金属の溶出を抑えるための安定化処理が要求される場合もあり、廃液処理に多大な費用が掛ることから廃液中の金属成分の有効利用が求められているが、これらの廃液中の金属成分が安価かつ製造容易に建材用の原材料として有効に利用されていないのが現状である。 In addition, waste liquids discharged from plating plants and light metal surface treatment establishments contain a wide variety of useful metal components, but sludge generated by processing these waste liquids is disposed of in landfills. Or are often disposed of by ocean dumping. In addition, in this waste liquid treatment, not only dehydration and drying of the waste liquid, but also stabilization treatment for suppressing metal elution by performing firing or concrete solidification treatment may be required. Since the cost is high, the effective use of the metal components in the waste liquid is required. However, the metal components in the waste liquid are not effectively used as raw materials for building materials at low cost and easily manufactured.
しかしながら、断熱性、電磁シールド性およびリサイクル性に優れ、且つ塗布性がある断熱材は無かった。近年、リフォームの需用が高まり、既存の建材に塗布するだけで、断熱性および電磁シールド性を高めることができる断熱材のニーズが高まっている。さらに、環境への配慮の要求が高まり、リサイクル性へのニーズも高まっている。
さらには、断熱材に発熱機能を付与したいという要請がある。
However, there was no heat insulating material excellent in heat insulating properties, electromagnetic shielding properties and recyclability and having coating properties. In recent years, demand for renovation has increased, and there is an increasing need for a heat insulating material that can enhance heat insulating properties and electromagnetic shielding properties simply by applying to existing building materials. Furthermore, the demand for environmental considerations is increasing, and the need for recyclability is also increasing.
Furthermore, there is a demand for imparting a heat generation function to the heat insulating material.
本考案はかかる事情に鑑みてなされたものであり、その目的は、断熱性、電磁シールド性およびリサイクル性に優れ、且つ塗布性がある建材を提供することにある。

以下、本考案の断熱材の製造に用いる上記断熱原材および導電性骨材について詳細に説明する。
［断熱原材］
中空ビーズ構造を有するアルミノ珪酸ソーダガラスである商品名ＸＯＬ−２００（ザ ピーキュー コーポレーション製、Southpoint, ValleyForge, Pennsylvania, U.S.）を用いることにより重量を非常に軽くすることができ、特定の樹脂と、顔料、分散剤、粘着剤等を配合することにより、熱伝導率が従来より低く、軽量で、かつ壁面等に塗布することが容易な断熱原材が得られる。すなわち、建物の外壁面、室内の壁面等に容易に塗布形成でき、断熱性に優れると共に耐久性も良好な塗布式断熱原材を提供する。
Hereafter, the said heat insulation raw material and conductive aggregate used for manufacture of the heat insulating material of this invention are demonstrated in detail.
[Insulation raw material]
By using the trade name XOL-200 (made by The PQ Corporation, Southpoint, ValleyForge, Pennsylvania, US), which is aluminosilicate soda glass having a hollow bead structure, the weight can be extremely reduced. By blending a dispersant, a pressure-sensitive adhesive, etc., a heat insulating raw material having a lower thermal conductivity than the conventional one, light weight, and easy to apply to a wall surface or the like can be obtained. That is, it provides a coating-type heat insulating raw material that can be easily applied and formed on an outer wall surface of a building, a wall surface in a room, and the like, and has excellent heat insulation and durability.
当該断熱原材の特徴は、アルミノ珪酸ソーダガラスと、顔料と、樹脂と、分散剤と、粘着剤とを含んでなる塗布式断熱原材であって、アルミノ珪酸ソーダガラスが、中空ビーズ構造であり粒径が１０〜５０μｍであり、かつその含有量が断熱原材の全重量の１０〜２０重量％であることにある。なお、アルミノ珪酸ソーダガラスの含有量については、断熱原材の全重量の１０〜２０重量％であるが、好ましくは１３〜１５重量％である。アルミノ珪酸ソーダガラスの含有量が１０％より小さいと断熱原材の断熱能力が低下することになり、また含有量が２０％より大きくなると断熱原材の壁面等への付着力が低下することになる。 The heat insulating raw material is characterized by a coating-type heat insulating raw material comprising aluminosilicate glass, a pigment, a resin, a dispersant, and an adhesive, and the aluminosilicate soda glass has a hollow bead structure. The particle size is 10 to 50 μm, and the content is 10 to 20% by weight of the total weight of the heat insulating raw material. In addition, about content of sodium aluminosilicate glass, although it is 10 to 20 weight% of the total weight of a heat insulation raw material, Preferably it is 13 to 15 weight%. If the content of the aluminosilicate glass is less than 10%, the heat insulation ability of the heat insulation raw material will be reduced, and if the content is more than 20%, the adhesion force to the wall surface of the heat insulation raw material will be reduced. Become.
アルミノ珪酸ソーダガラスは、空気層を含む中空ビーズ構造であり、具体的には、例えば上記商品名ＸＯＬ−２００（ザ ピーキュー
コーポレーション製）ないしこれの相当品が用いられる。顔料は、光を反射する白色顔料であることが好ましい。樹脂は、アクリルシリコン系の樹脂であり、これにセラミックスを混入することで、熱反射率を上げると共に、熱容量を小さくできる。これにより、高い蓄熱効果が得られる。

Specifically, for example, the trade name XOL-200 (manufactured by The PQ Corporation) or an equivalent thereof is used. The pigment is preferably a white pigment that reflects light. The resin is an acrylic silicon resin, and by mixing ceramics therein, the heat reflectance can be increased and the heat capacity can be reduced. Thereby, a high heat storage effect is obtained.
The dispersing agent makes the mixing of the aluminosilicate sodium glass, the resin and the pigment uniform when mixing the component materials.

Thereby, a high heat storage effect is obtained.
［導電性骨材］
本考案では、産業廃棄物を有効利用するため、廃棄物から導電性骨材を形成する。本考案で用いる廃棄物中の導電性骨材としては、特に金属メッキスラッジ、軽金属表面処理スラッジから発生する軽金属水酸化物または酸化物スラッジ、ブレーキ研磨粉、金属洗浄スラッジのような廃棄物などが対象となる。これらの廃棄物の中から導電性を有する材料を選別するには、所定の工場から排出される廃棄物を化学分析により、予め金属イオンの種類とその含有量を検査し、所定の範囲内に入る場合には、そのロット全体を使用原料とするもので、含有成分を特別に分別、抽出する必要はない。
[Conductive aggregate]
In the present invention, in order to effectively use industrial waste, conductive aggregate is formed from waste. Examples of the conductive aggregate in the waste used in the present invention include metal plating sludge, light metal hydroxide or oxide sludge generated from light metal surface treatment sludge, brake polishing powder, waste such as metal cleaning sludge, etc. It becomes a target. In order to select conductive materials from these wastes, the type and content of metal ions are inspected in advance by chemical analysis of the waste discharged from a given factory, and within a given range. When entering, the entire lot is used as a raw material, and it is not necessary to separate and extract the contained components.
個々の産業廃棄物に含まれる導電性成分の含有量は、排出される工場によっても異なるが、通常、約１０重量％から約５０重量％と幅があり、それぞれの導電性にも強弱の異った性質がある。その為、導電性を持った廃棄物を一種類ではなく、少なくとも二種類以上の廃棄物を混合し、それぞれの持っている化学成分の相互作用によって活性な化学反応を起させることを予め考慮した上で混合した方が、より強い導電性を発揮する事が判明した。 The content of the conductive component contained in each industrial waste varies depending on the factory to which it is discharged, but it usually ranges from about 10% to about 50% by weight. There is a nature. Therefore, we considered in advance that not only one kind of conductive waste but also two or more kinds of waste are mixed and an active chemical reaction is caused by the interaction of each chemical component. It turned out that the one mixed above exhibits stronger conductivity.
そこで、数十種類の産業廃棄物の中から、導電性を有する廃棄物を選択し、それ等の組み合わせや配合を変えて導電性骨材を調製した。このようにして調製した骨材をモルタルと混合してセメント固化物を作成し、抵抗測定器を用いてそれらの体積固有抵抗値の比較実験を繰返し、廃棄物の組み合わせの選択を行った。 Thus, conductive waste was selected from among several tens of types of industrial waste, and conductive aggregates were prepared by changing their combination and composition. Aggregates prepared in this way were mixed with mortar to produce cement solidified material, and comparison experiments of their volume resistivity values were repeated using a resistance measuring device to select a combination of wastes.
例えば、電解コンデンサー製造工場でのアルミニウムの陽極酸化皮膜処理時に発生する懸濁液のスラッジにはＡｌ（ＯＨ）3 が約４５重量％含有されている。このアルミスラッジを４０重量％モルタルに混合して作成した導電性骨材組成物の体積固有抵抗値は１０3
Ω・ｃｍであったが、アルミスラッジを３５重量％にし、廃酸処理センターから排出される金属洗浄スラッジ（銅を１２重量％含有）を５重量％混合した導電性骨材をモルタルと混合して作成した導電性骨材組成物の体積固有抵抗値は１０2
Ω・ｃｍであった。いずれも供試体は三点ずつ作成し比較したが結果は同じであった。従って、導電性骨材の素材は二種類以上の廃棄物の混合が望ましい事が判明した。このように、本考案の導電性骨材は、一種類の産業廃棄物に限定されるものではなく、二種類以上の産業廃棄物の混合が望ましい。
For example, about 45% by weight of Al (OH) 3 is contained in the sludge of the suspension generated during the anodizing treatment of aluminum at an electrolytic capacitor manufacturing plant. The volume resistivity of the conductive aggregate composition prepared by mixing this aluminum sludge with 40% by weight mortar is 10 3.
Although it was Ω · cm, 35% by weight of aluminum sludge was mixed with conductive mortar mixed with 5% by weight of metal cleaning sludge (containing 12% by weight of copper) discharged from the waste acid treatment center. The volume resistivity value of the conductive aggregate composition prepared by the above is 10 2
It was Ω · cm. In all cases, three specimens were prepared and compared, but the results were the same. Accordingly, it has been found that it is desirable to mix two or more kinds of conductive aggregate materials. Thus, the conductive aggregate of the present invention is not limited to one type of industrial waste, and it is desirable to mix two or more types of industrial waste.
上記道電性骨材の抵抗値としては、ＪＩＳＫ６９１１に準拠して測定した場合、体積固有抵抗１０4 Ω・ｃｍ未満が好ましい。体積固有抵抗値が１０4 Ω・ｃｍを超えると、得られた骨材を建材原材料中に添加して壁材及び床材などの建材を形成した場合に、静電気帯電防止や電磁波シールド等に十分な効果が得られない。また、導電性骨材の含水率は２０％以下が好ましい。含水率が２０％を超えると、最終的に用いられる建材組成物粉体の均質混合が困難となり、固化強度が低下し、建材として好ましくない。導電性骨材の粒径は、１ｍｍ以下の粉体が好ましい。粒径が１ｍｍを超える粉体では、固化強度が低下すると共に、導電性が不均一となり、最終的に用いられる導電性建材としては好ましくない。 The resistance value of the electroconductive aggregate is preferably less than 10 4 Ω · cm when measured according to JISK6911. If the volume resistivity exceeds 10 4 Ω · cm, the resulting aggregate is added to the building material raw material to form building materials such as walls and floors, which is sufficient for antistatic and electromagnetic shielding. The effect is not obtained. The moisture content of the conductive aggregate is preferably 20% or less. When the water content exceeds 20%, it is difficult to homogeneously mix the building material composition powder to be finally used, and the solidification strength is lowered, which is not preferable as a building material. The conductive aggregate preferably has a particle size of 1 mm or less. If the particle size exceeds 1 mm, the solidification strength decreases and the conductivity becomes non-uniform, which is not preferable as a conductive building material to be finally used.
本考案で用いる導電性骨材は、一般建材の材料の中に３０〜５０重量％混入する事によって即導電性をもった壁パネル及び床タイル、さらにはモルタル仕上げ施工が容易となり、一般建築構造体の内装施工法により、簡単に静電気帯電防止及び電磁波シールドの機能を発揮する。 The conductive aggregate used in the present invention is easily mixed with 30 to 50% by weight of general building materials, so that wall panels and floor tiles with immediate conductivity and mortar finishing can be easily constructed. By the body interior construction method, it easily demonstrates the functions of antistatic and electromagnetic shielding.
［本考案の実施形態の断熱材］

これは、導電性骨材を全重量の１０％未満にすると、本実施形態の断熱材に電圧を印加して発熱体とした場合に、２次元領域上の各点においては発熱温度にバラツキが発生ｓるう。
また、導電性骨材を全重量の３５％を超えて混入すると、粘度が高くなり、塗料として壁等に塗布することが困難になる。
[Insulation material of the embodiment of the present invention]
The heat insulating material of the embodiment of the present invention is manufactured by sufficiently stirring and mixing the conductive aggregate and the heat insulating raw material so that the conductive aggregate is 10 to 35% of the total weight. At this time, if necessary, water is added and mixed.
This is because, when the conductive aggregate is less than 10% of the total weight, when a voltage is applied to the heat insulating material of this embodiment to form a heating element, the heating temperature varies at each point on the two-dimensional region. Occurred.
Further, when the conductive aggregate exceeds 35% of the total weight, the viscosity becomes high and it becomes difficult to apply it as a paint to a wall or the like.
［効果］
本実施形態の断熱材は、所定の電圧を印加すると発熱し、発熱体として機能する。
本実施形態では、上記導電性骨材を全重量の１０〜３５％としたことで、高い発熱効率、各領域での均一な発熱、並びに塗料としての適切な粘度を得ることができる。
[effect]
The heat insulating material of this embodiment generates heat when a predetermined voltage is applied, and functions as a heating element.
In the present embodiment, by setting the conductive aggregate to 10 to 35% of the total weight, high heat generation efficiency, uniform heat generation in each region, and appropriate viscosity as a paint can be obtained.
本実施形態の断熱材は、それに混入されている断熱原材として、上述した中空ビーズ構造で粒径が１０〜５０μｍのアルミノ珪酸ソーダガラスを用いることにより、ガラスが赤外線を９０％程度反射するが、さらにガラスが中空ビーズ構造であることにより、透過した熱を中空ビーズ部分で吸収することができるので、ほぼ完全に熱を遮断することができる。そのため、この断熱材の熱伝導率を、従来の断熱材に対して０．０３〜０．０５程度の範囲の非常に低い値にすることができる。そのため、建物の外壁側あるいは室内の内壁面に塗布形成することにより、外部からの夏季の熱気の侵入を遮断し、冬期に暖房の熱の室外への伝導を効果的に遮断できる。 Although the heat insulating material of this embodiment uses the aluminosilicate sodium glass with a particle size of 10 to 50 μm as the heat insulating raw material mixed therein, the glass reflects infrared rays by about 90%. Furthermore, since the glass has a hollow bead structure, the transmitted heat can be absorbed by the hollow bead portion, so that the heat can be cut off almost completely. Therefore, the heat conductivity of this heat insulating material can be set to a very low value in the range of about 0.03 to 0.05 with respect to the conventional heat insulating material. Therefore, by applying and forming on the outer wall side of the building or the inner wall surface of the room, intrusion of hot air from the outside in the summer can be blocked, and conduction of the heat of heating to the outside can be effectively blocked in the winter.
また、中空ビーズ構造のアルミノ珪酸ソーダガラスとしたことにより、比重が０．１０〜０．１３程度と非常に軽量であるため沈殿することがなく、塗布を容易に行うことができ、スプレー、はけ塗り、ローラ等によって均一に壁面に塗布することができる。特に凹凸面にも均一に塗布することができる。さらに、アルミノ珪酸ソーダガラスが非常に軽量であるため、壁面に断熱材の層を形成することにより、軽量のアルミノ珪酸ソーダガラスが表面に集められ、そのため、硬質のアルミノ珪酸ソーダガラスが断熱材層全体を保護することになり、断熱材層の耐久性が非常に高められ、また防錆効果も得られる。 In addition, since the aluminosilicate soda glass has a hollow bead structure, the specific gravity is very light, about 0.10 to 0.13, so it does not precipitate and can be applied easily. It can be uniformly applied to the wall surface by brushing, roller or the like. In particular, it can be applied evenly to uneven surfaces. Furthermore, since the aluminosilicate glass is very lightweight, by forming a layer of insulation on the wall surface, the lightweight aluminosilicate glass is collected on the surface, so that the hard aluminosilicate glass is the insulation layer The entire structure is protected, the durability of the heat insulating material layer is greatly enhanced, and an antirust effect is also obtained.
さらに、中空ビーズ構造のアルミノ珪酸ソーダガラスが塗布された層に分布しているので、その中を伝播する音波が中空部分で吸収されるため、大きな遮音効果が得られる。また、この断熱材が、アクリルシリコン系の樹脂であり、これにセラミックスを混入することで、熱反射率を上げると共に、熱容量を小さくできる。さらに、２ｍｍ程度の厚さの塗布によっても亀裂が生じることはなく、耐久性にも優れている。 Furthermore, since the aluminosilicate soda glass having a hollow bead structure is distributed in the coated layer, the sound wave propagating through the layer is absorbed by the hollow portion, so that a great sound insulation effect is obtained. In addition, this heat insulating material is an acrylic silicon resin, and by mixing ceramics therein, the heat reflectance can be increased and the heat capacity can be reduced. Furthermore, cracks do not occur even when the thickness is about 2 mm, and the durability is excellent.
また、本実施形態の断熱材は、上述した導電性骨材を用いることで、高い電磁シールド性を持つことができる。これにより、簡単に静電気帯電防止及び電磁波シールドの目的を達成することができる。 Moreover, the heat insulating material of this embodiment can have a high electromagnetic shielding property by using the conductive aggregate described above. Thereby, the objective of antistatic charge and electromagnetic wave shielding can be achieved easily.

上述した本考案の断熱材の構成で、サイズ：φ３００ｍｍの円盤状の試験対象を製造し、加熱試験を行った。
ここで、上記導電性骨材が全重量の７，８，９％の第１の試験対象と、上記導電性骨材が全重量の１０，１１，１２，１３％の第２の試験対象とについて試験を行った。
試験は、図２に示すように、通電電極２００，２０１からスライダックを使用して試験対象に電圧をかけ、試験対象の加熱過程と到達温度の測定を行った。
試験対象は、φ３００ｍｍの円盤状で、厚み約１〜２ｍｍ（表面は凹凸がなく平面、僅かに湾曲）である。試験対象をカーボンシートを間に挟み固定した。
測定点は、図２に示すＡ１，Ａ２，Ａ３の３点である。
[Experimental result]
With the configuration of the heat insulating material of the present invention described above, a disk-shaped test object having a size of φ300 mm was manufactured, and a heating test was performed.
Here, the first test object whose conductive aggregate is 7, 8, 9% of the total weight, and the second test object whose conductive aggregate is 10, 11, 12, 13% of the total weight, The test was conducted.
In the test, as shown in FIG. 2, a voltage was applied to the test object from the energized electrodes 200 and 201 using a slidac, and the heating process and ultimate temperature of the test object were measured.
The test object is a disk shape having a diameter of 300 mm and a thickness of about 1 to 2 mm (the surface is flat with no irregularities and slightly curved). The test object was fixed with a carbon sheet in between.
There are three measurement points A1, A2 and A3 shown in FIG.
、図２に示すように、通電電極２００，２０１からスライダックを使用して試験対象に電圧をかけ、供給電圧を順次上げていき、加熱状況を見ながら試験を行った。
上記導電性骨材が全重量の７，８，９％の第１の試験対象は、室温における電極間の抵抗値が１．１，１．０．０．９ＭΩと高く、ＡＣ１００Ｖを供給しても、流れた電流は０．５０，０．５３，０．５５ｍＡであり殆ど流れない。従って、加熱には至らなかった。
また、各点での発熱温度に著しいバラツキが生じた。
As shown in FIG. 2, a voltage was applied to the test object from the energizing electrodes 200 and 201 using a slidac, the supply voltage was increased sequentially, and the test was performed while observing the heating state.
The first test object in which the conductive aggregate is 7, 8, 9% of the total weight has a high resistance value between the electrodes at room temperature of 1.1, 1.0.0.9 MΩ, and AC 100 V is supplied. However, the flowed current is 0.50, 0.53, 0.55 mA and hardly flows. Therefore, heating was not reached.
In addition, there was significant variation in the heat generation temperature at each point.
上記導電性骨材が全重量の１０，１１，１２，１３％の第２の試験対象は、室温における電極間の抵抗値が１．２０，１．１９，１，１８５，１．１８ｋΩである。ＡＣ１５０Ｖで約１５分加熱したところ、図２に示す測定点Ａ１が６５，６６，６７，６８℃、測定点Ａ２が７４，７５，７７，７９℃、測定点Ａ３が７６，７７，７９，８０℃となった。通電電流が約２６０ｍＡ、消費電力が約３９Ｗとなった。また、各点での発熱温度に大きなバラツキは生じなかった。また、上記導電性骨材が全重量の１３〜３５％の第２の試験対象についても同様に各点での発熱温度に大きなバラツキは生じなかった。
このように、導電性骨材を全重量の１０％未満にすると、本実施形態の断熱材に電圧を印加した場合の発熱効率が著しく低く、発熱対として機能しない。一方、導電性骨材を全重量の１０％以上にすると１０％未満の場合に比べて発熱体としての発熱効率が著しく向上した。また、２次元領域上の各点においては発熱温度にバラツキが殆ど生じなかった。
The second test object in which the conductive aggregate is 10, 11, 12, 13% of the total weight has resistance values between the electrodes at room temperature of 1.20, 1.19, 1,185, 1.18 kΩ. . When heated at AC 150 V for about 15 minutes, measurement point A1 shown in FIG. 2 is 65, 66, 67, 68 ° C., measurement point A 2 is 74, 75, 77, 79 ° C., and measurement point A 3 is 76, 77, 79, 80. It became ℃. The energization current was about 260 mA, and the power consumption was about 39 W. Further, there was no great variation in the heat generation temperature at each point. Similarly, the second test subject in which the conductive aggregate was 13 to 35% of the total weight did not have a large variation in the heat generation temperature at each point.
Thus, if the conductive aggregate is less than 10% of the total weight, the heat generation efficiency when a voltage is applied to the heat insulating material of this embodiment is extremely low, and it does not function as a heat generating pair. On the other hand, when the conductive aggregate was made 10% or more of the total weight, the heat generation efficiency as a heating element was remarkably improved as compared with the case of less than 10%. Moreover, there was almost no variation in the heat generation temperature at each point on the two-dimensional region.
さらに、導電性骨材を全重量の３５％を超えて混入すると、塗料として樹脂成型するための粘度を確保できない。そのため、壁に塗布しての層を形成することができなくなってしまう。これに対して、導電性骨材を全重量の３５％以下にすると、塗料として樹脂成型することが可能になった。 Furthermore, when conductive aggregate exceeds 35% of the total weight, the viscosity for resin molding as a paint cannot be ensured. Therefore, it becomes impossible to form a layer applied to the wall. On the other hand, when the conductive aggregate is 35% or less of the total weight, it becomes possible to mold the resin as a paint.
［応用形態］
本実施形態の断熱材は、壁パネル及び床タイル、さらにはモルタル仕上げ施工が容易となり、一般建築構造体の内装施工に用いることができる。また、塗布式であるため、リフォーム時などに既存の壁などに吹き付けるだけで、その機能を向上できる。

Moreover, since it is a coating type, the function can be improved only by spraying on the existing wall etc. at the time of reform.
