Abstract
Description
本発明は、建築物の保温性を向上させて火災時には建築物の壁体および鉄骨を火炎から保護する耐火断熱材として利用可能であり、あるいは他の用途にも利用可能な、気泡を含む硬化体の製造方法、およびこの気泡を含む硬化体を製造するための材料に関する。 The present invention can be used as a refractory heat insulating material that improves the heat insulation of a building and protects the wall and steel frame of the building from a flame in the event of a fire, or can be used for other purposes. The present invention relates to a method for producing a body, and a material for producing a cured body containing the bubbles.
建築現場において断熱材料を躯体に吹き付けて塗工する際、取り扱いが容易であって断熱性を有する発泡ウレタンを用いるのが一般的である。例として特開平１１−３４３６８１号公報（特許文献１）、特開平１１−０２９９９６号公報（特許文献２）および特開平０８−２５３９７６号公報（特許文献３）に記載の技術を列挙することができる。 When a thermal insulation material is sprayed onto the housing at the construction site and applied, it is common to use urethane foam that is easy to handle and has thermal insulation properties. As examples, the techniques described in JP-A-11-34381 (Patent Document 1), JP-A-11-029996 (Patent Document 2) and JP-A-08-253976 (Patent Document 3) can be listed. .
発泡ウレタンは断熱性を有するものの、プラスチックであるため熱に弱く、耐火性に劣る。しかも火災時には有毒ガスが発生するという問題がある。そこで、例えば特開平１１−９３２９６号公報（特許文献４）に記載のような技術が提案されている。特許文献４に記載の発泡性無機耐火被覆材は、珪酸塩と微粉状シリカを主たる成分として含み、火災発生時に発泡層を形成して鉄骨の温度上昇を遅延させるものである。 Although urethane foam has a heat insulating property, it is a plastic, so it is weak against heat and inferior in fire resistance. Moreover, there is a problem that toxic gas is generated in the event of a fire. Therefore, for example, a technique as described in JP-A-11-93296 (Patent Document 4) has been proposed. The foamable inorganic fireproof coating material described in Patent Document 4 contains silicate and finely divided silica as main components, and forms a foamed layer in the event of a fire to delay the temperature rise of the steel frame.
しかしながら、特許文献４に記載の発泡性無機耐火被覆材は、加熱しない限り発泡しない耐火材にすぎず、発泡ウレタンのように室温で断熱材として機能しない。したがって建築物の断熱施工を行う場合には、発泡ウレタンまたはグラスウールといった断熱材料を別途準備して施工しなければならず、施工に工数を要していた。 However, the foamable inorganic fireproof coating material described in Patent Document 4 is merely a fireproof material that does not foam unless heated, and does not function as a heat insulating material at room temperature like foamed urethane. Therefore, when performing heat insulation construction of a building, heat insulation material such as urethane foam or glass wool has to be separately prepared and constructed, which requires man-hours for the construction.
また特許文献４に記載の発泡性無機耐火被覆材は、液体のまま施工現場に搬入しなければならず、取り扱いが不便であった。 Moreover, the foamable inorganic fireproof coating material described in Patent Document 4 had to be carried into the construction site as a liquid, and was inconvenient to handle.
本発明は、上述の実情に鑑み、取り扱いが容易であり、断熱材として使用できる他、高温に耐える耐火材として建物の躯体を火災から保護することができる建築材料として好適な、気泡を含む硬化体の製造方法と、気泡を含む硬化体を製造するための材料粉体および材料を提供することを目的とする。 In view of the above circumstances, the present invention is easy to handle, can be used as a heat insulating material, and is suitable as a building material that can protect a building frame from a fire as a refractory material that can withstand high temperatures. An object of the present invention is to provide a method for producing a body, and a material powder and a material for producing a cured body containing bubbles.
この目的のため本発明による気泡を含む硬化体の材料粉体は、粉末状の形態を呈し、水に溶くことによってゾル状スラリーとなり、所定時間経過後に自己発泡して硬化する硬化体の材料であって、粉末状の形態を呈する珪酸ソーダ１００重量部に対して、シリカ３〜３０重量部と、高炉スラグ、セメント、石こう、珪酸カルシウム、パーライト、発泡火山灰、セピオライト、ホワイトカーボンおよびゼオライトからなる群から選ばれた少なくとも１つ以上の材料を含む硬化材３０〜８０重量部と、炭酸カルシウム、ベントナイト、タルク、カオリン、水酸化アルミニウム、珪砂、珪石、珪藻土、無機系繊維、有機系繊維および酸化チタンからなる群から選ばれた少なくとも１つ以上の材料を含む充填材３０〜７０重量部とを備える。 For this purpose, the material powder of the cured body containing bubbles according to the present invention is a material of a cured body that exhibits a powdery form, becomes a sol slurry by dissolving in water, and self-foams and cures after a predetermined time. A group consisting of 3 to 30 parts by weight of silica, 100 parts by weight of sodium silicate in a powder form, and blast furnace slag, cement, gypsum, calcium silicate, perlite, foamed volcanic ash, sepiolite, white carbon and zeolite. 30 to 80 parts by weight of a hardening material containing at least one material selected from the group consisting of calcium carbonate, bentonite, talc, kaolin, aluminum hydroxide, silica sand, silica stone, diatomaceous earth, inorganic fibers, organic fibers and titanium oxide 30 to 70 parts by weight of a filler containing at least one material selected from the group consisting of:
かかる本発明の材料粉体によれば、硬化体の材料が粉体であることから、施工現場における取り扱いが容易になる。粉体は液体よりも取り扱いが容易であり、液状の建築材料や、２液混合の建築材料と比較してこぼれたり、品質が劣化したり変質したりする懸念が少ないためである。 According to the material powder of the present invention, since the material of the cured body is powder, handling at the construction site is facilitated. This is because powder is easier to handle than liquid, and there is less concern about spillage, deterioration in quality, or alteration compared to liquid building materials or two-component mixed building materials.
しかも、この材料粉体に加える水の量を厳格に計量測定しなくてもよく、現場で水の量を調節することができることから、施工が容易であり、施工性が向上する。 Moreover, it is not necessary to strictly measure the amount of water added to the material powder, and since the amount of water can be adjusted on site, the construction is easy and the workability is improved.
また本発明によれば、施工現場において加える水量を調整することにより、気泡の大きさを調整することができる。したがって施工現場の裁量で、発泡率を大きくして比重の軽い硬化体としての耐火断熱材を得ることができるし、発泡率を小さくして比重の重い硬化体としての耐火断熱材を得ることもできる。 Moreover, according to this invention, the magnitude | size of a bubble can be adjusted by adjusting the amount of water added in a construction site. Therefore, at the discretion of the construction site, it is possible to obtain a refractory heat insulating material as a hardened body with a low specific gravity by increasing the foaming rate, or to obtain a refractory heat insulating material as a hardened body with a high specific gravity by reducing the foaming rate. it can.
また本発明によれば、施工現場にハンドミキサーまたはモルタルミキサー等の攪拌装置を準備しておき、粉体の材料と水とを施工現場に持ち込んで両者を攪拌混合することによって、気泡を含む硬化体の硬化前の不定形状態を容易に得られる。かかる硬化前の状態はスラリー状であり、コテ塗りすることによって、容易に耐火断熱施工を行うことができる。そして、現場に合わせた形状の硬化体を容易に得られる。またかかる実施形態によれば、水量を調整することによって気泡の大きさを施工現場で調整することができる。 In addition, according to the present invention, a stirrer such as a hand mixer or a mortar mixer is prepared at the construction site, and a powder material and water are brought into the construction site and mixed together to stir and contain bubbles. An indeterminate state before curing of the body can be easily obtained. Such a state before curing is in the form of a slurry, and by applying a trowel, it is possible to easily perform fireproofing and heat insulation. And the hardening body of the shape match | combined with the field can be obtained easily. Moreover, according to this embodiment, the magnitude | size of a bubble can be adjusted on a construction site by adjusting the amount of water.
また、本発明の材料粉体に水を加えたスラリーが自己発泡および硬化することにより硬化体が形成され、かかる硬化体を耐火断熱材として利用することができる。硬化体は、単位体積中の気泡数のうち８０％以上の気泡が、隣り合う気泡から独立している。かかる硬化体によれば、独立した気泡が多数形成されることから、硬化体の内部で熱対流が生じない。したがって、熱伝導率が低く、壁材として使用することにより、結露を防止することが可能になり、人体のアレルギー症状を引き起こすカビの繁殖を防止することができる。 Further, a slurry obtained by adding water to the material powder of the present invention is self-foamed and cured to form a cured body, and the cured body can be used as a refractory heat insulating material. In the cured body, 80% or more of the number of bubbles in a unit volume is independent of adjacent bubbles. According to such a cured body, since many independent bubbles are formed, thermal convection does not occur inside the cured body. Therefore, heat conductivity is low, and it becomes possible to prevent dew condensation by using it as a wall material, and to prevent the growth of mold that causes allergic symptoms of the human body.
また形成される硬化体は気泡を多数含むことから、軽量であり、保温機能、および遮熱機能、遮音機能等を有する。したがって本発明によれば、保温室、遮熱材、および遮音壁を施工現場で容易に製造することができる。気泡を含む硬化体は、建築用途に限られるものではなく、電熱器の底板等、工夫次第であらゆる用途に利用可能である。 Moreover, since the hardened | cured body formed contains many bubbles, it is lightweight and has a heat retention function, a heat insulation function, a sound insulation function, etc. Therefore, according to the present invention, it is possible to easily manufacture a greenhouse, a heat insulating material, and a sound insulating wall at a construction site. The hardened body containing air bubbles is not limited to architectural use, and can be used for any application depending on the device such as the bottom plate of an electric heater.
また本発明による気泡を含む硬化体の材料は、液体および粉体を混合攪拌することによってゾル状スラリーとなり、所定時間経過後に自己発泡して硬化する硬化体の材料であって、液体材料および粉体材料の組み合わせである。すなわち、１材料として液体の珪酸ソーダ１００重量部よりなる液体材料を備える。他の１材料として、シリカ３〜３０重量部と、高炉スラグ、セメント、石こう、珪酸カルシウム、パーライト、発泡火山灰、セピオライト、ホワイトカーボンおよびゼオライトからなる群から選ばれた少なくとも１つ以上の材料を含む硬化材３０〜８０重量部と、炭酸カルシウム、ベントナイト、タルク、カオリン、水酸化アルミニウム、珪砂、珪石、珪藻土、無機系繊維、有機系繊維および酸化チタンからなる群から選ばれた少なくとも１つ以上の材料を含む充填材３０〜７０重量部とを有する粉体材料を備える。 Further, the material of the cured body containing bubbles according to the present invention is a cured material that becomes a sol-like slurry by mixing and stirring the liquid and the powder, and is self-foamed and cured after a predetermined time. It is a combination of body materials. That is, a liquid material composed of 100 parts by weight of liquid sodium silicate is provided as one material. Another material includes 3 to 30 parts by weight of silica and at least one material selected from the group consisting of blast furnace slag, cement, gypsum, calcium silicate, perlite, foamed volcanic ash, sepiolite, white carbon, and zeolite. 30 to 80 parts by weight of a hardener, and at least one or more selected from the group consisting of calcium carbonate, bentonite, talc, kaolin, aluminum hydroxide, silica sand, silica stone, diatomaceous earth, inorganic fibers, organic fibers, and titanium oxide A powder material having 30 to 70 parts by weight of a filler containing the material is provided.
かかる本発明の材料によれば、施工現場で液体材料および粉体材料を混合攪拌することによって、耐火性能および断熱性能を備えた気泡を含む硬化体を施工現場で容易に製造することができる。しかも、現場に合わせた形状の硬化体を容易に得られる。また、軽量であり、保温機能、遮熱機能、および遮音機能等を備えた気泡を含む硬化体を施工現場で容易に製造することができる。気泡を含む硬化体は、建築用途に限られるものではなく、電熱器の底板等、工夫次第であらゆる用途に利用可能である。 According to the material of the present invention, by mixing and stirring the liquid material and the powder material at the construction site, it is possible to easily produce a cured body containing bubbles having fire resistance and heat insulation performance at the construction site. In addition, it is possible to easily obtain a cured body having a shape adapted to the site. Moreover, it is lightweight and can easily produce a cured body containing bubbles having a heat retaining function, a heat insulating function, a sound insulating function, and the like at a construction site. The hardened body containing air bubbles is not limited to architectural use, and can be used for any application depending on the device such as the bottom plate of an electric heater.
本発明は１実施形態に限定されず、硬化材は高炉スラグを含み、充填材は炭酸カルシウム、ベントナイトおよび酸化チタンを含むものであってもよい。かかる実施形態によれば、高炉スラグを含むことからコスト上有利である。また酸化チタンを含むことから抗菌性能および最終的な硬化体の強度が向上する。 The present invention is not limited to one embodiment, and the hardener may include blast furnace slag, and the filler may include calcium carbonate, bentonite, and titanium oxide. According to such an embodiment, the blast furnace slag is included, which is advantageous in terms of cost. Moreover, since titanium oxide is contained, the antibacterial performance and the strength of the final cured body are improved.
また本発明による気泡を含む硬化体の製造方法は、粉末状の形態を呈する珪酸ソーダ１００重量部と、シリカ３重量部〜３０重量部と、高炉スラグ、セメント、石こう、珪酸カルシウム、パーライト、発泡火山灰、セピオライト、ホワイトカーボンおよびゼオライトからなる群から選ばれた少なくとも１つ以上の材料を含む硬化材３０重量部〜８０重量部と、炭酸カルシウム、ベントナイト、タルク、カオリン、水酸化アルミニウム、珪砂、珪石、珪藻土、無機系繊維、有機系繊維および酸化チタンからなる群から選ばれた少なくとも１つ以上の材料を含む充填材３０重量部〜７０重量部とを備える材料粉体を用意する工程と、予め用意した材料粉体に対して水を加えてスラリーを製造するスラリー製造工程と、スラリーを対象領域に塗工または流し込む塗工工程と、塗工または流し込んだスラリーを自己発泡させて硬化させる工程とを備え、スラリー製造工程の完了から塗工工程の完了までを所定時間内で行う。 Moreover, the manufacturing method of the hardening body containing the bubble by this invention is 100 weight part of sodium silicate which exhibits a powder form, 3 weight part-30 weight part of silica, blast furnace slag, cement, gypsum, calcium silicate, perlite, foaming 30 to 80 parts by weight of a hardener containing at least one material selected from the group consisting of volcanic ash, sepiolite, white carbon and zeolite, calcium carbonate, bentonite, talc, kaolin, aluminum hydroxide, silica sand, and silica Preparing a material powder comprising 30 parts by weight to 70 parts by weight of a filler containing at least one material selected from the group consisting of diatomaceous earth, inorganic fibers, organic fibers, and titanium oxide; Apply slurry to the target area by adding slurry to the prepared material powder to produce slurry. A coating step of pouring has a coating or the poured slurry and a step of curing by self-foaming, performs the completion of the slurry preparation step to the completion of the coating process within a predetermined time.
かかる本発明の製造方法によれば、粉体の材料を用意すればよいことから、施工現場へ容易に搬入することが可能になり、取り扱いが容易になる。また、本発明の材料粉体を施工現場に搬入し、施工現場にて水を加えて攪拌混合することによってスラリーを作成し、スラリーを施工の対象領域となる鉄骨または壁体に塗工することによって容易に施工することができる。本発明の材料粉体から作られるゾル状スラリーは大気温で化学反応を起こして自己発泡および硬化するため、発泡および硬化のために特別な処置（加熱など）および器具を必要とせず、施工性が極めてよい。しかも、この自己発泡および硬化は数十分で完了することから、施工に要する時間が短くて済む。 According to the manufacturing method of the present invention, it is only necessary to prepare a powder material, so that it can be easily carried into the construction site and is easy to handle. In addition, the material powder of the present invention is brought into the construction site, water is added at the construction site, and the slurry is prepared by stirring and mixing, and the slurry is applied to the steel frame or wall body that is the target region of construction. Can be easily constructed. Since the sol-like slurry made from the material powder of the present invention undergoes a chemical reaction at ambient temperature and self-foams and hardens, no special treatment (heating, etc.) and tools are required for foaming and hardening, and workability is improved. Is very good. Moreover, since this self-foaming and curing is completed in several tens of minutes, the time required for construction can be shortened.
また本発明によれば、従来の発泡ウレタンと比較して耐火性能が飛躍的に向上し、しかも従来の耐火被覆材が室温で断熱性能を有しないという欠点を補う硬化体を得ることができる。なお、本発明の製造方法において、施工の対象領域は建築施工に限られず、例えば、電気器具の底板や、保温、遮熱等の必要な部位などに塗工することができる。 Further, according to the present invention, it is possible to obtain a cured body that has a dramatic improvement in fire resistance compared to conventional urethane foam, and that compensates for the disadvantage that conventional fireproof coating materials do not have heat insulation performance at room temperature. In addition, in the manufacturing method of this invention, the object area | region of construction is not restricted to building construction, For example, it can apply to the required parts, such as a baseplate of an electric appliance, heat retention, heat insulation.
また、本発明の製造方法は、施工現場に限られず、工場等で型枠にスラリーを流し込み、硬化後に型枠から取り出される成型体にも適用可能である。工場等で製造された気泡を含む硬化体の成型体は、建築資材として施工現場に搬入されてもよい。また、工場等で電気器具の部品に塗工されてもよい。 Moreover, the manufacturing method of this invention is not restricted to a construction site, It is applicable also to the molded object which pours a slurry into a formwork in a factory etc. and takes out from a formwork after hardening. A molded body of a hardened body containing air bubbles manufactured in a factory or the like may be carried into a construction site as a building material. Further, it may be applied to parts of electric appliances at a factory or the like.
スラリー製造工程において加える水の量は４０〜１２０重量部である。加える水の量を調節することによって、硬化体の中の気泡の大きさを制御するとよい。ここで加える水の量を４０〜１２０重量部と規定したのは、水が多すぎると発泡率が大きすぎて最終的な硬化体の中に含まれる気泡が大きくなりすぎるためであり、水が少なすぎると発泡率が小さすぎて最終的な硬化体の中に含まれる気泡が小さくなりすぎるためである。なお水の加え方は、粉体に水を少しずつ投入する方法であっても、水に粉体を少しずつ投入する方法であっても、粉体および水を混合攪拌容器へ同時に投入する方法であってもよく、特に規定はない。 The amount of water added in the slurry production process is 40 to 120 parts by weight. The size of the bubbles in the cured body may be controlled by adjusting the amount of water to be added. The amount of water added here is defined as 40 to 120 parts by weight because if the amount of water is too much, the foaming rate is too large and the bubbles contained in the final cured product become too large. This is because if the amount is too small, the foaming rate is too small and the bubbles contained in the final cured body become too small. The method of adding water is a method of adding water and powder into the mixing and stirring vessel at the same time, whether it is a method of adding water to the powder little by little or a method of adding powder to the water little by little. There is no particular rule.

It can be easily constructed by coating the resulting steel frame or wall. The sol-like slurry made from the powder and liquid sodium silicate of the present invention undergoes a chemical reaction at high temperatures and self-foams and hardens, requiring special treatment (such as heating) and equipment for foaming and hardening. The workability is very good. Moreover, since this self-foaming and curing is completed in several tens of minutes, the time required for construction can be shortened.
また本発明によれば、従来の発泡ウレタンと比較して耐火性能が飛躍的に向上し、しかも従来の耐火被覆材が室温で断熱性能を有しないという欠点を補う硬化体を得ることができる。なお、本発明の製造方法において、施工の対象領域は建築施工に限られず、例えば、電気器具の底板や、保温や、遮熱等の必要な部位などに塗工することができる。 Further, according to the present invention, it is possible to obtain a cured body that has a dramatic improvement in fire resistance compared to conventional urethane foam, and that compensates for the disadvantage that conventional fireproof coating materials do not have heat insulation performance at room temperature.

The cured product containing bubbles obtained from the material powder and the material of the present invention can be used for any application, such as a bottom plate of an electric heater, in addition to the use of a building material.
以下、本発明の実施の形態を、実施例に基づき詳細に説明する。 Hereinafter, embodiments of the present invention will be described in detail based on examples.
まず、一実施例となる気泡を含む硬化体の材料粉体につき説明すると、反応材として粉体の珪酸ソーダ（日本化学工業株式会社製 商品名「粉末３号珪酸ソーダ」）を１００重量部と、シリカ（フェロシリカ）１５重量部とを用意する。珪酸ナトリウムは粉体であれば、他の商品であってもよい。 First, the material powder of the cured body containing air bubbles as an example will be described. As a reaction material, powder sodium silicate (trade name “Powder No. 3 sodium silicate” manufactured by Nippon Chemical Industry Co., Ltd.) is 100 parts by weight. And 15 parts by weight of silica (ferrosilica). Other products may be used as long as the sodium silicate is a powder.
硬化材として、粉体の高炉スラグを６０重量部用意する。硬化材として高炉スラグの他、セメント、石こう、珪酸カルシウム、パーライト、発泡火山灰（シラスバルーン）、セピオライト、ホワイトカーボン、ゼオライトのうち少なくとも１つ以上の粉体材料を含んでいてもよい。完成する耐火断熱材が適切な強度となるよう、用意する硬化材は３０重量部〜８０重量部の範囲でよい。 As a hardener, 60 parts by weight of powdered blast furnace slag is prepared. In addition to blast furnace slag, at least one powder material of cement, gypsum, calcium silicate, perlite, foamed volcanic ash (shirasu balloon), sepiolite, white carbon, and zeolite may be included as the hardener. The curing material to be prepared may be in the range of 30 to 80 parts by weight so that the completed refractory heat insulating material has appropriate strength.
充填材として、粉体の炭酸カルシウム１０重量部と、粉体のベントナイト１０重量部と、粉体の酸化チタン１５重量部とを用意する。充填材は、炭酸カルシウム、ベントナイト、タルク、カオリン、水酸化アルミニウム、珪砂、珪石、珪藻土、無機系繊維、有機系繊維、酸化チタンのうち少なくとも１つ以上の粉体材料を含んでいればよい。無機系繊維は、ひび割れ、収縮防止を目的として充填材に含めることができ、たとえばセピオライト、ワラストナイト、マイクロカーボン、カーボンナノチューブ等を充填材に加える。あるいは、無機系繊維を主体としつつ、木粉といった植物質繊維、羽毛といった動物質繊維、セルロース、ポリプロピレン等の有機系繊維を充填材に加えてもよい。完成する耐火断熱材が適切な強度となるよう、用意する充填材は３０重量部〜７０重量部の範囲でよい。 As fillers, 10 parts by weight of calcium carbonate powder, 10 parts by weight of bentonite powder, and 15 parts by weight of titanium oxide powder are prepared. The filler may contain at least one powder material of calcium carbonate, bentonite, talc, kaolin, aluminum hydroxide, silica sand, silica stone, diatomaceous earth, inorganic fibers, organic fibers, and titanium oxide. Inorganic fibers can be included in the filler for the purpose of preventing cracks and shrinkage. For example, sepiolite, wollastonite, microcarbon, carbon nanotubes and the like are added to the filler. Alternatively, vegetable fibers such as wood powder, moving substance fibers such as feathers, and organic fibers such as cellulose and polypropylene may be added to the filler while mainly containing inorganic fibers. The filler to be prepared may be in the range of 30 to 70 parts by weight so that the completed refractory heat insulating material has an appropriate strength.
なお、上述した酸化チタンを含むことにより、酸化チタンの熱反射効果および防カビ効果を享受することができる。また酸化チタンを加えることによって硬化後の強度が大きくなる。耐火断熱材は酸化チタンを含むことによって白色に近い色合いとなる。 In addition, by including the titanium oxide mentioned above, the heat | fever reflection effect and anti-mold effect of titanium oxide can be enjoyed. Moreover, the intensity | strength after hardening becomes large by adding a titanium oxide. A fireproof heat insulating material becomes a color close | similar to white by including a titanium oxide.
上述したこれら反応材と、硬化材と、充填材とを混合した材料粉体は、持ち運びが可能であり、この粉体自体は運搬中に化学反応を起こすことがない。 The material powder obtained by mixing the reaction material, the curing material, and the filler described above can be carried, and the powder itself does not cause a chemical reaction during transportation.
次に、この気泡を含む硬化体の材料粉体から硬化体を作成して耐火断熱材として利用する、耐火断熱材の施工方法について説明する。 Next, the construction method of the fireproof heat insulating material which makes a hardened body from the material powder of the hardened | cured body containing this bubble and uses it as a fireproof heat insulating material is demonstrated.
上述した材料粉体を施工現場に搬入し、施工現場では水を用意する。上述した珪酸ソーダ１００重量部に対して５０重量部の水を施工現場で混合し、水と材料粉体が均一になるまで攪拌する。攪拌は市販のハンドミキサーでよい。材料粉体および水を混ぜ合わせることによってゾル状スラリーを作成する。 The above-mentioned material powder is carried into the construction site, and water is prepared at the construction site. 50 parts by weight of water is mixed at the construction site with respect to 100 parts by weight of the above-described sodium silicate, and stirred until the water and the material powder are uniform. A commercially available hand mixer may be used for stirring. A sol slurry is prepared by mixing the material powder and water.
なお、ゾル状スラリーの粘度は、前述した硬化材および充填材の量を加減することによって容易に調整可能である。 Note that the viscosity of the sol-like slurry can be easily adjusted by adjusting the amount of the above-described curing material and filler.
水を加えることによってゾル状スラリーは自己発泡および硬化の化学反応を開始する。気泡の大きさは、加える水量に比例する。このため、気泡を大きくして硬化体の比重を軽くしたい場合には、水を多めに加えるとよい。反対に、気泡を小さくして硬化体の強度を大きくしたい場合には、水を少なめに加えるとよい。気泡の大きさが適切となるように加える水量は４０重量部〜１２０重量部の範囲になる。 By adding water, the sol slurry initiates a self-foaming and curing chemical reaction. The size of the bubbles is proportional to the amount of water added. For this reason, when it is desired to reduce the specific gravity of the cured body by enlarging the bubbles, it is preferable to add more water. On the other hand, when it is desired to reduce the bubbles and increase the strength of the cured body, a small amount of water may be added. The amount of water added so that the size of the bubbles is appropriate is in the range of 40 to 120 parts by weight.
攪拌混合が完了したら、ゾル状スラリーを直ちに施工対象に塗工する。建築物の塗工対象は垂直面であっても水平面であってもよく、また鉄骨およびモルタル壁に対して、ゾル状スラリーは液垂れすることなく確りと付着する。本実施例では、硬化材や充填材の量を適宜加減することによりゾル状スラリーの粘度を調整して、垂れにくい性状とすることが可能であり、モルタル壁および鉄骨以外の表面が円滑な壁体などの鉛直面への塗工にも好適である。 When the stirring and mixing is completed, the sol slurry is immediately applied to the construction object. The object to be applied to the building may be a vertical surface or a horizontal surface, and the sol slurry adheres to the steel frame and the mortar wall without dripping. In this embodiment, it is possible to adjust the viscosity of the sol slurry by appropriately adjusting the amount of the hardener and filler, and to make it difficult to sag, and the surface other than the mortar wall and the steel frame is smooth. It is also suitable for coating on vertical surfaces such as the body.
塗工にあたっては、コテを用いて塗る方法や、スプレーガンなどのノンガスのガンで吹き付ける方法でよい。吹き付け工法の場合は、ゾル状スラリーを圧縮して吹き付けてもよく、フロンガスや可燃性ガスなど格別のスプレーガスを必要としない。 For coating, a method using a trowel or a method of spraying with a non-gas gun such as a spray gun may be used. In the case of the spraying method, the sol slurry may be compressed and sprayed, and no special spray gas such as chlorofluorocarbon or flammable gas is required.
施工の季節にもよるが、攪拌混合の完了から１０分〜２０分ぐらいすると、ゾル状スラリーが化学反応により自己発泡および硬化を開始する。したがって、スラリー製造工程の完了から塗工工程の完了までを所定時間内で行う。気温が低い冬場であれば、攪拌混合の完了から２０分以内に塗工を完了させることが好ましい。反対に気温が高い夏場であれば、攪拌混合の完了から１０分以内に塗工を完了させることが好ましい。また、スラリーの温度を管理する等、何らかの促進手段または遅延手段を用いて、スラリー製造工程の完了から塗工工程の完了までの所定時間を調整してもよい。 Although depending on the season of construction, the sol-like slurry starts self-foaming and curing due to a chemical reaction after about 10 to 20 minutes from the completion of stirring and mixing. Therefore, the process from the completion of the slurry production process to the completion of the coating process is performed within a predetermined time. In winter when the temperature is low, it is preferable to complete the coating within 20 minutes after the completion of stirring and mixing. On the other hand, in the summertime when the temperature is high, it is preferable to complete the coating within 10 minutes from the completion of the stirring and mixing. Moreover, you may adjust the predetermined time from completion of a slurry manufacturing process to completion of a coating process using some promotion means or delay means, such as managing the temperature of a slurry.
発泡プロセスは、以下の化学式で表すことができる。反応材としての珪酸ソーダ（SiO2）の一部が化１に示すように加水分解する。 The foaming process can be represented by the following chemical formula: A part of sodium silicate (SiO 2 ) as a reaction material is hydrolyzed as shown in Chemical Formula 1.
Na2O・SiO2 ＋ H2O →← NaOH ＋ NaHSiO3 ・・・・（化１） このNaHSiO3はゾルであり、化２に示すように一部がさらに加水分解する。 Na 2 O.SiO 2 + H 2 O → ← NaOH + NaHSiO 3 ... (Chemical Formula 1) This NaHSiO 3 is a sol, and a part thereof is further hydrolyzed as shown in Chemical Formula 2.
NaHSiO3＋ H2O →← NaOH ＋ H2SiO3 ・・・・（化２）
このNaSiO3はゾルである。なお、化１および化２の「→←」は、反応が左辺から右辺へ進む他、右辺から左辺へも進み得ることを示す。
NaHSiO 3 + H 2 O → ← NaOH + H 2 SiO 3 (2)
This NaSiO 3 is a sol. Note that “→ ←” in Chemical Formula 1 and Chemical Formula 2 indicates that the reaction can proceed from the left side to the right side as well as from the right side to the left side.
反応材としてのシリカ(Si)は、水酸化ナトリウム(NaOH)と水（H2O）の存在において、化３に示すように水素ガス(H2)を発生する。 Silica (Si) as a reaction material generates hydrogen gas (H 2 ) as shown in Chemical formula 3 in the presence of sodium hydroxide (NaOH) and water (H 2 O).
2 NaOH ＋ Si ＋ H2O → Na2O・SiO2 ＋ 2H2 ・・・・（化３） 化３に示すように水酸化ナトリウムが消費されると化１右辺および化２右辺の水酸化ナトリウムが不足し、これら化１および化２の平衡が破れて加水分解が右辺へ向かって進行する。化３の化学反応は左辺の水および珪素が無くなるまで続く。また化３は発熱を伴う反応であり、蒸発によっても左辺の水が無くなる。以上より、本実施例のゾル状スラリーは硬化する。 2 NaOH + Si + H 2 O → Na 2 O.SiO 2 + 2H 2 .. (Chemical Formula 3) When sodium hydroxide is consumed as shown in Chemical Formula 3, the right side of Chemical Formula 1 and the right side of Chemical Formula 2 are hydroxylated. Sodium is deficient, the equilibrium of these chemicals 1 and 2 is broken, and hydrolysis proceeds toward the right side. The chemical reaction of Chemical Formula 3 continues until water and silicon on the left side disappear. Chemical reaction 3 is an exothermic reaction, and water on the left side disappears even by evaporation. From the above, the sol slurry of this example is cured.
化３で生成される水素ガスは、ゾル状スラリーの中で気泡を形成する。かかる気泡は、隣り合う気泡同士で連通しない独立した気泡を多く含む。このようにゾル状スラリーは自己発泡する。 The hydrogen gas generated in Chemical Formula 3 forms bubbles in the sol slurry. Such bubbles include many independent bubbles that do not communicate with each other between adjacent bubbles. Thus, the sol-like slurry is self-foamed.
なお、施工現場で粉体材料に水を加えることの利点として、水の攪拌混合からしばらく経って自己発泡および硬化が開始することが挙げられる。つまり、水の攪拌混合後すぐには化学反応が開始しないため、塗工に必要な時間を確保することができる。 An advantage of adding water to the powder material at the construction site is that self-foaming and curing start after a while from the stirring and mixing of water. That is, since a chemical reaction does not start immediately after stirring and mixing water, the time required for coating can be secured.
このようにして、塗工完了後３０分〜４０分程度経つとゾル状スラリーの自己発泡および硬化が完了する。つまり、攪拌混合完了から自己発泡および硬化が完了するまでの時間は４０分〜１時間程度である。気温が低い冬場であれば、攪拌混合完了から自己発泡および硬化が完了するまで１時間ほど要する。反対に気温が高い夏場であれば、攪拌混合完了から自己発泡および硬化が完了するまで４０分ほど要する。なお、ゾル状スラリーの自己発泡および硬化には外部からの加熱を一切要しない。 In this way, self-foaming and curing of the sol-like slurry are completed after about 30 to 40 minutes after the completion of coating. That is, the time from the completion of stirring and mixing to the completion of self-foaming and curing is about 40 minutes to 1 hour. In winter when the temperature is low, it takes about 1 hour from the completion of stirring and mixing to the completion of self-foaming and curing. On the contrary, in summer when the temperature is high, it takes about 40 minutes from the completion of stirring and mixing to the completion of self-foaming and curing. Note that no external heating is required for self-foaming and curing of the sol slurry.
このように本実施例の気泡を含む硬化体の製造方法における化学反応は４０分〜１時間で完了し、最終的な耐火断熱材としての硬化体が完成する。化学反応自体が完了しても硬化体が湿り気を帯びている場合もあるが、４時間程度で完全に乾燥および硬化する。本実施例は特殊なスプレーガンを用いてゾル状スラリーにガスを連行して強制的に気泡を作成するものではない。したがって本実施例によれば、市販される一般的なスプレーガンで吹き付け塗工することができる。完成した硬化体は、化学的に安定であり、時間とともに変質することなく存在する。 Thus, the chemical reaction in the method for producing a cured body containing bubbles according to the present example is completed in 40 minutes to 1 hour, and a cured body as a final refractory heat insulating material is completed. Even if the chemical reaction itself is completed, the cured body may be moistened, but completely dry and cure in about 4 hours. In this embodiment, bubbles are not forcibly created by entraining a gas in a sol slurry using a special spray gun. Therefore, according to the present Example, it can spray-coat with the common spray gun marketed. The finished cured body is chemically stable and exists without changing with time.
図１は本実施例の製造方法から得られる最終的な硬化体を示す断面図であり、図２は同実施例の硬化体を拡大して示す斜視図である。図１に示すように、７ｍｍ厚で塗工したゾル状スラリーは、自己発泡によって２０ｍｍ厚に増大する。また、形成された気泡の多くは、それぞれが独立し、互いに連通しているものは少ない。したがって、硬化体の内部で熱対流が起こらず、断熱性能に優れ、結露が生じない。 FIG. 1 is a cross-sectional view showing a final cured body obtained from the manufacturing method of the present embodiment, and FIG. 2 is an enlarged perspective view showing the cured body of the same embodiment. As shown in FIG. 1, the sol slurry applied with a thickness of 7 mm increases to a thickness of 20 mm by self-foaming. In addition, many of the formed bubbles are independent of each other, and few are in communication with each other. Therefore, heat convection does not occur inside the cured body, heat insulation performance is excellent, and condensation does not occur.
本実施例の硬化体は、独立した気泡を多数含み、比重が０．５〜０．６であることから軽量であり、高層建築物の耐火断熱材として有利である。本実施例の硬化体は、図２に示すように表面が凹凸形状になる。したがってこの凹凸形状を建築意匠として取り入れることができる。あるいは、硬化前に当て板で押さえることによって、表面を円滑にすることも可能である。 The cured body of the present example contains a large number of independent bubbles and has a specific gravity of 0.5 to 0.6, so that it is lightweight and advantageous as a fireproof heat insulating material for high-rise buildings. As shown in FIG. 2, the cured body of this example has an uneven surface. Therefore, this uneven shape can be incorporated as an architectural design. Alternatively, the surface can be smoothed by pressing with a backing plate before curing.
なお、美観の更なる向上のため等の理由により、本実施例の硬化体に表面処理が要求される場合、硬化体の表面に漆喰をさらに塗工してもよい。硬化体の表面に漆喰を塗工すること自体、何ら問題ない。本実施例の硬化体を外壁として施工した場合、硬化体の表面に漆喰を塗工することにより防水性能が向上する。あるいは本実施例の硬化体を内装材として用いる場合、硬化体の上にパネルを貼り付けること自体、何ら問題ない。 In addition, when surface treatment is requested | required by the reason for the further improvement of the beauty | look, etc., you may further apply stucco on the surface of a hardening body. There is no problem in applying plaster to the surface of the cured body. When the cured body of this example is constructed as an outer wall, waterproof performance is improved by applying stucco to the surface of the cured body. Or when using the hardening body of a present Example as an interior material, there is no problem in sticking a panel on a hardening body itself.
また本実施例の硬化体は無機質の材料で形成されており、１３００度の高温にも耐えることができる。したがって、すぐれた耐火性能を有する。 The cured body of this example is formed of an inorganic material and can withstand a high temperature of 1300 degrees. Therefore, it has excellent fire resistance.
本実施例の硬化体につき、断熱性能を測定する試験を行った。まず供試体として、自己発泡および硬化状態で１７ｍｍ厚の壁状の硬化体と、３０ｍｍ厚の壁状の硬化体の２体を用意した。各供試体につき、一方壁面には赤外線電球を向けておき、他方壁面を断熱材からなる箱で覆い、一方壁面および他方壁面に熱電対を取り付けた。そして室温（２２〜２６度）で、一方壁面に赤外線を照射して一方壁面を加熱し、一方壁面の受熱温度および他方壁面の温度を、加熱開始から２４０分が経過するまでの間、それぞれ計測した。 The cured body of the present example was tested for measuring heat insulation performance. First, as a specimen, two bodies, a 17 mm thick wall-shaped cured body and a 30 mm thick wall-shaped cured body in a self-foamed and cured state, were prepared. For each specimen, an infrared light bulb was directed to one wall surface, the other wall surface was covered with a box made of a heat insulating material, and thermocouples were attached to the one wall surface and the other wall surface. Then, at room temperature (22 to 26 degrees), one wall surface is irradiated with infrared rays to heat one wall surface, and the heat receiving temperature of the one wall surface and the temperature of the other wall surface are measured until 240 minutes have elapsed from the start of heating. did.
図３は１７ｍｍ厚の壁状の硬化体の断熱試験結果を示すグラフであり、図４は３０ｍｍ厚の壁状の硬化体の断熱試験結果を示すグラフであり、図５は、断熱試験結果をまとめた図表である。 FIG. 3 is a graph showing a heat insulation test result of a wall-shaped cured body having a thickness of 17 mm, FIG. 4 is a graph showing a heat insulation test result of a wall-shaped cured body having a thickness of 30 mm, and FIG. It is the summary chart.
１７ｍｍ厚の壁状の硬化体は、図３および図５に示すように、加熱開始後１０分経過後の一方壁面温度（受熱温度）と他方壁面温度（試験体裏面温）との差（断熱温度）は平均６．４度であった。また加熱開始後２時間以上経ち、一方壁面温度（受熱温度）が摂氏５０度かつ幅２度の範囲で安定する間の断熱温度は平均６．５度であった。この安定時の断熱度は、６．５度を５０度で除算して１３％になる。 As shown in FIGS. 3 and 5, the 17 mm thick wall-shaped cured body has a difference (heat insulation) between one wall surface temperature (heat receiving temperature) and the other wall surface temperature (back surface temperature of the test body) after 10 minutes from the start of heating. The temperature was an average of 6.4 degrees. In addition, after 2 hours or more after the start of heating, while the wall surface temperature (heat receiving temperature) was stabilized in the range of 50 degrees Celsius and 2 degrees wide, the adiabatic temperature was 6.5 degrees on average. The heat insulation degree at the time of stability becomes 13% by dividing 6.5 degrees by 50 degrees.
３０ｍｍ厚の壁状の硬化体は、図４および図５に示すように、加熱開始後１０分経過後の断熱温度は平均１０．４度であった。また加熱開始後３時間以上経ち、一方壁面温度（受熱温度）が摂氏５６度かつ幅２度の範囲で安定する間の断熱温度は平均１０．７度であった。この安定時の断熱度は、１０．７度を５６度で除算して１９％になる。 As shown in FIGS. 4 and 5, the 30 mm thick wall-shaped cured body had an average heat insulation temperature of 10.4 degrees after 10 minutes from the start of heating. Further, after 3 hours or more after the start of heating, while the wall surface temperature (heat receiving temperature) was stabilized in the range of 56 degrees Celsius and 2 degrees wide, the adiabatic temperature averaged 10.7 degrees. The heat insulation degree at the time of stability becomes 19% by dividing 10.7 degrees by 56 degrees.
次に、他の実施例となる気泡を含む硬化体の材料を説明すると、前述した粉体の珪酸ソーダに代えて、液体の珪酸ソーダ（日本工業規格Ｋ１４０８：珪酸ナトリウム３号 大阪珪曹株式会社製）を１００重量部用意する。珪酸ナトリウム３号は水あめ状のほぼ透明な液体である。これに代えて珪酸ナトリウム２号あるいは１号でもよい。 Next, a description will be given of the material of the cured body containing bubbles as another example. Instead of the powdered sodium silicate, liquid sodium silicate (Japanese Industrial Standard K1408: sodium silicate No. 3 Osaka Silica Co., Ltd.) 100 parts by weight is prepared. Sodium silicate 3 is a candy-like, almost transparent liquid. Alternatively, sodium silicate No. 2 or No. 1 may be used.
液体の珪酸ソーダとは別に、反応材としてのシリカ、硬化材、および充填材を、上述した重量部と同量それぞれ用意する。これらの粉体は別々に用意しても、予め混合しておいてもよい。 Apart from the liquid sodium silicate, silica as a reaction material, a curing material, and a filler are prepared in the same amount as the above-mentioned parts by weight. These powders may be prepared separately or previously mixed.
そして、液体の珪酸ソーダと、粉体のシリカ、硬化材および充填材とをそれぞれ施工現場に搬入し、施工現場で攪拌混合する。攪拌は市販のハンドミキサーでよい。これらを混ぜ合わせることによって、硬化体が硬化する前のゾル状スラリーを作成する。 Then, liquid sodium silicate, powdered silica, hardener, and filler are carried into the construction site and stirred and mixed at the construction site. A commercially available hand mixer may be used for stirring. By mixing these, a sol-like slurry before the cured body is cured is prepared.
ゾル状スラリーは上述した化１〜化３の化学反応によって自己発泡および硬化を開始する。 The sol-like slurry starts self-foaming and curing by the chemical reaction of Chemical Formulas 1 to 3 described above.
自己発泡および硬化が完了すると、前述した実施例と同じ耐火断熱機能を備えた硬化体が完成する。 When the self-foaming and curing are completed, a cured body having the same fireproof and heat insulating function as the above-described embodiment is completed.
