従来の断熱パネルが設けられた建築物の断面図である。It is sectional drawing of the building in which the conventional heat insulation panel was provided. 本発明の一実施例を示したものであって、複合断熱パネルの断面図である。BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a cross-sectional view of a composite heat insulation panel, showing an embodiment of the present invention. 本発明の一実施例を示したものであって、複合断熱パネルの使用状態図である。BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows an embodiment of the present invention, and is a usage state diagram of a composite heat insulation panel. 本発明の一実施例を示したものであって、エトリンガイトの写真である。1 shows an embodiment of the present invention and is a photograph of ettringite. 本発明の一実施例を示したものであって、速硬性ポリマーセメントモルタル組成物の毛細管気孔浸透防止機能を模式的に示した模式図である。BRIEF DESCRIPTION OF THE DRAWINGS It is the schematic diagram which showed one Example of this invention, Comprising: The capillary pore penetration | infiltration prevention function of the quick-hardening polymer cement mortar composition was shown typically.

以下、添付図面を参照して本発明の実施例について詳細に説明する。   Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

図２、図３に示されているように、本発明にかかる複合断熱パネル１００は、基本的に、発泡性合成樹脂材質によって形成された断熱材１１０と、合成樹脂材質によって形成され、幅方向に複数の中空部１２１が形成されるとともに、断熱材１１０の表面に接着された中空板１２０と、ポリマーセメントモルタル材質によって中空板１２０の表面に形成されたモルタル層１３０とを含んで構成される。   As shown in FIGS. 2 and 3, the composite heat insulation panel 100 according to the present invention is basically formed of a heat insulating material 110 made of a foamable synthetic resin material, and a synthetic resin material. A plurality of hollow portions 121 are formed, and includes a hollow plate 120 bonded to the surface of the heat insulating material 110 and a mortar layer 130 formed on the surface of the hollow plate 120 with a polymer cement mortar material. .

ここで、断熱材１１０は、発泡スチレンフォーム、発泡ウレタンフォームなどのような発泡性合成樹脂材質によって形成され、中空板１２０は、ポリプロピレンのような合成樹脂材質によって形成され、中空部１２１は、結露防止、断熱、防音のための空気層を形成する。   Here, the heat insulating material 110 is formed of a foamable synthetic resin material such as foamed styrene foam or foamed urethane foam, the hollow plate 120 is formed of a synthetic resin material such as polypropylene, and the hollow portion 121 is condensed. Form an air layer for prevention, insulation and soundproofing.

モルタル層１３０を形成する材質であるポリマーセメントは、結合材であるセメントの一部をポリマー混和剤（ポリマーラテックス、ディスパージョン、再乳化型ポリマー粉末、水溶性ポリマー、液状樹脂、モノマーなど）に代替した材料であって、強度はもちろん、接着性、水密性などに極めて優れていることが知られている。   The polymer cement that is the material that forms the mortar layer 130 replaces part of the cement that is the binder with a polymer admixture (polymer latex, dispersion, re-emulsifiable polymer powder, water-soluble polymer, liquid resin, monomer, etc.). It is known that the material is extremely excellent not only in strength but also in adhesion and water tightness.

本発明は、断熱材１１０の表面に中空板１２０を接着し、その表面に前述したポリマーセメント材質によるモルタルによってモルタル層１３０を形成することにより、断熱パネル自体が仕上げ材を兼ねるようにしたものである。   In the present invention, the hollow plate 120 is bonded to the surface of the heat insulating material 110, and the mortar layer 130 is formed on the surface by the mortar made of the polymer cement material, so that the heat insulating panel itself also serves as a finishing material. is there.

これは、次のような効果がある。   This has the following effects.

第一、壁体１０に対して複合断熱パネル１００を設けることだけで、従来の断熱パネル２０の設置および仕上げ材３０の設置という二重作業と同じ結果を得るようにし、作業にかかる手間と費用を低減することができる。   First, by providing the composite heat insulating panel 100 on the wall body 10, the same result as the double operation of installing the conventional heat insulating panel 20 and the finishing material 30 is obtained, and labor and cost for the operation are reduced. Can be reduced.

第二、ポリマーセメントモルタルは、１〜２ｍｍ程度に薄く塗布しても、従来の仕上げ材が有する性能以上を十分に発揮できるため、従来の断熱パネル２０および仕上げ材３０の二重構造に比べて、断熱構造の厚さを画期的に減らすことができ、結果的に建築物の内部空間を拡大することができる。   Second, the polymer cement mortar can sufficiently exhibit the performance of the conventional finishing material even if it is thinly applied to about 1 to 2 mm. Compared to the conventional double structure of the heat insulating panel 20 and the finishing material 30 In addition, the thickness of the heat insulating structure can be dramatically reduced, and as a result, the internal space of the building can be expanded.

第三、表面のモルタル層１３０を形成するポリマーセメントは、基本的に接着性、水密性に優れた材料であり、本発明にかかるパネルは、断熱材１１０、中空板１２０およびモルタル層１３０が一体に形成された状態として提供されて壁面に設けられるため、密な断熱構造を形成することができ、冬期における結露現象の発生を防止することができる。   Third, the polymer cement forming the surface mortar layer 130 is basically a material having excellent adhesion and water tightness, and the panel according to the present invention includes the heat insulating material 110, the hollow plate 120, and the mortar layer 130 as one body. Since it is provided as a state formed on the wall surface and provided on the wall surface, a dense heat insulating structure can be formed, and the occurrence of the dew condensation phenomenon in winter can be prevented.

断熱材１１０および中空板１２０は、多様な材質の接着剤によって接着できるが、接着剤としてウレタン材質の接着剤を適用する場合、付着に伴う変形および環境汚染を最小化することができるという利点が追加される。   The heat insulating material 110 and the hollow plate 120 can be bonded by various kinds of adhesives. However, when a urethane adhesive is applied as the adhesive, there is an advantage that deformation and environmental pollution accompanying adhesion can be minimized. Added.

以下、モルタル層１３０を形成するポリマーセメントモルタルの具体的な実施例について説明する。   Hereinafter, specific examples of the polymer cement mortar for forming the mortar layer 130 will be described.

前記ポリマーセメントモルタルは、速硬性セメント１２−２０重量％と、普通セメント１０−３０重量％と、珪砂（６０−１００メッシュ）３０−５０重量％と、硫酸ナトリウム５−１０重量％と、スチレン−エチレンビニルバーサテイトエマルジョン１５−２５重量％と、ステアリン酸塩４−８重量％と、添加剤０．０１−１０重量％とを含む構成を採ることが好ましい。   The polymer cement mortar is composed of 12-20% by weight fast-setting cement, 10-30% by weight ordinary cement, 30-50% by weight silica sand (60-100 mesh), 5-10% by weight sodium sulfate, styrene- It is preferable to adopt a constitution containing 15-25% by weight of ethylene vinyl versatate emulsion, 4-8% by weight of stearate, and 0.01-10% by weight of additives.

ポリマーセメントモルタルを表面仕上げ材として使用するにあたって最も問題となり得る点は、ポリマーセメントモルタルが硬化しながら亀裂が発生し、このような亀裂またはポリマーセメントモルタルの内部に存在する毛細管気孔を通して水、揮発性有機化合物（ＶＯＣｓ）、二酸化炭素や亜硫酸ガスのような、環境に有害なイオンなどの浸透が行われるという点である。   The most problematic point in using polymer cement mortar as a surface finish is that the polymer cement mortar hardens as it hardens and cracks occur, and water, volatiles through such cracks or capillary pores present inside the polymer cement mortar. The penetration of ions harmful to the environment such as organic compounds (VOCs), carbon dioxide and sulfurous acid gas is performed.

前記組成は、速硬性セメントと硫酸ナトリウムの反応によってモルタルの毛細管気孔内部にエトリンガイト結晶を生成させ、スチレン−エチレンビニルバーサテイトエマルジョンによってモルタルの毛細管気孔内部に膨潤性ポリマーと弾性フィルムを形成させることにより、ポリマーセメントモルタルの乾燥時に収縮による亀裂を防止し、水、揮発性有機化合物（ＶＯＣｓ）、二酸化炭素や亜硫酸ガスのような、環境に有害なイオンなどが毛細管気孔を通して浸透することを完壁に遮断するという利点がある。   The composition is obtained by forming ettringite crystals inside capillary pores of mortar by the reaction of fast-setting cement and sodium sulfate, and forming a swellable polymer and an elastic film inside capillary pores of mortar with styrene-ethylene vinyl versatate emulsion. , Preventing cracking due to shrinkage when drying polymer cement mortar, and making it possible for water, volatile organic compounds (VOCs), carbon dioxide, sulfur dioxide, and other harmful ions to penetrate through capillary pores There is an advantage of blocking.

以下、構成成分別に詳細に説明する。   Hereinafter, it demonstrates in detail according to a component.

前記速硬性セメントは、普通セメントに比べて、硬化時間が１時間〜３時間程度短縮する特性を有するものである。   The fast-curing cement has a characteristic that the setting time is shortened by about 1 to 3 hours as compared with ordinary cement.

このような速硬性セメントの速硬特性の発現は、セメントの水和過程で生成されるエトリンガイトという鉱物によって行われるが、エトリンガイトは、速硬性セメント構成鉱物中のＣ３Ａ（３ＣａＯＡｌ２Ｏ３）成分が水和初期に硫酸イオンと反応しながら迅速に生成される。 Such fast-hardening cement exhibits fast-hardening characteristics by a mineral called ettringite produced during the hydration process of cement. Ettringite is a C 3 A (3CaOAl 2 O 3 ) in a fast-hardening cement constituent mineral. Ingredients are rapidly produced while reacting with sulfate ions in the early stages of hydration.

この時生成されるエトリンガイトは、１マイクロメートル以下の結晶として生成され、これらは、速硬特性を示すだけでなく、モルタルの毛細管空隙に位置して空隙を充填することにより、水分の蒸発による収縮を防止し、収縮による亀裂を防止し、水の浸透や有害なイオンの浸透を防止する役割を果たす。   The ettringite produced at this time is produced as crystals of 1 micrometer or less, and these show not only fast-hardening properties but also shrinkage due to evaporation of water by filling the voids located in the capillary voids of the mortar. Prevents cracking due to shrinkage, and prevents the penetration of water and harmful ions.

したがって、微細なエトリンガイト結晶によって充填された空隙は、水密性を増大させる。   Thus, voids filled with fine ettringite crystals increase water tightness.

前記エトリンガイトの形態を図４に示した。   The form of the ettringite is shown in FIG.

図４に示されているように、エトリンガイト結晶は、１マイクロメートル以下の球体の結晶としてモルタルの毛細管空隙に生成される。   As shown in FIG. 4, ettringite crystals are formed in mortar capillary voids as spherical crystals of 1 micrometer or less.

このような速硬性セメントとしては、普通セメントの粉末度である３，５００ｃｍ２／ｇに比べて、粉末度が５，５００ｃｍ２／ｇ以上の微粉形態のものが使用される。 As such a fast-hardening cement, a fine powder having a fineness of 5,500 cm 2 / g or more is used as compared with 3,500 cm 2 / g which is the fineness of ordinary cement.

速硬性セメントは、組成物の総重量に対して、１２−２０重量％で含まれることが好ましいが、１２重量％未満で含まれると、モルタル組成物の硬化時間が長くなり、２０重量％を超えると、極めて迅速に硬化して作業性を確保できないという欠点があるからである。   The fast-setting cement is preferably included in an amount of 12 to 20% by weight based on the total weight of the composition. However, if it is included in an amount of less than 12% by weight, the setting time of the mortar composition becomes long, and 20% by weight is required. This is because if it exceeds, there is a drawback that it is hardened very quickly and workability cannot be secured.

また、硫酸ナトリウムは、組成物の総重量に対して、５−１０重量％で含まれることが好ましいが、５重量％未満で含まれると、エトリングガイトが十分に生成されにくく、１０重量％を超えると、エトリンガイトの生成が過度に多くなり、エトリンガイトによる膨脹亀裂が発生する問題があるからである。   Further, sodium sulfate is preferably contained in an amount of 5 to 10% by weight based on the total weight of the composition. However, if it is contained in an amount of less than 5% by weight, ettringite is hardly formed and 10% by weight. This is because, if it exceeds, the production of ettringite is excessively increased, and there is a problem that expansion cracks are generated by ettringite.

前記普通セメントは、一般的に用いられているポルトランドセメントを意味し、組成物の総重量に対して、１０−３０重量％で含まれる場合、モルタル組成物の物性に優れ、経済的にも好ましい。   The ordinary cement means a commonly used Portland cement. When the cement is contained in an amount of 10 to 30% by weight based on the total weight of the composition, the physical properties of the mortar composition are excellent and economically preferable. .

前記珪砂（６０−１００メッシュ）は、モルタル組成物に一般的に用いられているものを使用し、シリカ含有量が９０％以上のものを使用することが好ましい。   As the silica sand (60-100 mesh), those generally used in mortar compositions are used, and those having a silica content of 90% or more are preferably used.

前記珪砂は、組成物の総重量に対して、３０−５０重量％で含まれる場合、材料分離の防止、モルタルの圧縮強度の発現およびモルタルの表面仕上げ性の面で好ましい効果を提供する。   When the silica sand is contained in an amount of 30 to 50% by weight based on the total weight of the composition, it provides favorable effects in terms of prevention of material separation, expression of compressive strength of the mortar and surface finish of the mortar.

前記ステアリン酸塩は、防水剤成分であって、当該分野において広く用いられている通常のステアリン酸塩が使用できる。   The stearate is a waterproofing agent component, and a normal stearate widely used in the field can be used.

このようなステアリン酸塩は、組成物の総重量に対して、４−８重量％で含まれる場合、モルタル組成物の防水性と全体物性の面で好ましい効果を提供する。   When the stearate salt is contained at 4 to 8% by weight based on the total weight of the composition, it provides a favorable effect in terms of waterproofness and overall physical properties of the mortar composition.

また、前記ステアリン酸塩のような、既存に知られた防水性材料のほか、スチレン−エチレンビニルバーサテイトエマルジョンが使用できる。   In addition to the known waterproof material such as stearate, styrene-ethylene vinyl versatate emulsion can be used.

スチレン−エチレンビニルバーサテイトエマルジョンは、膨潤特性に優れた材質であって、モルタルの毛細管気孔内部に膨潤性ポリマーおよび弾性フィルムを形成するため、水や、揮発性有機化合物（ＶＯＣｓ）、その他のセメント系材料に深刻な害を及ぼすイオンなどの浸透が防止される。   Styrene-ethylene vinyl versatate emulsion is a material with excellent swelling characteristics, and forms swellable polymer and elastic film inside capillary pores of mortar, so water, volatile organic compounds (VOCs), other cements Infiltration of ions and the like that cause serious harm to the system material is prevented.

特に、水や水分が浸透する場合、モルタルの毛細管気孔内部にスチレン−エチレンビニルバーサテイトエマルジョンによって生成された膨潤性ポリマーが膨潤しながら、水や水分の浸透を遮断する。   In particular, when water or moisture permeates, the swellable polymer produced by the styrene-ethylene vinyl versatate emulsion swells inside the capillary pores of the mortar while blocking the penetration of water and moisture.

また、モルタルの毛細管気孔内部に生成された弾性フィルムによってモルタルの伸縮率が増加し、乾燥後の亀裂も防止される。   In addition, the elastic film generated inside the capillary pores of the mortar increases the stretch rate of the mortar and prevents cracks after drying.

スチレン−エチレンビニルバーサテイトエマルジョンの膨潤特性を図５に模式的に示した。   The swelling characteristic of the styrene-ethylene vinyl versatate emulsion is schematically shown in FIG.

図５に示しているように、スチレン−エチレンビニルバーサテイトによって形成された膨潤性ポリマーは、モルタルの毛細管気孔内部に存在しながら、外部から水分や有害イオンなどが浸透すれば膨潤し、毛細管気孔を塞ぐ役割を果たす。   As shown in FIG. 5, the swellable polymer formed by styrene-ethylene vinyl versatate is present inside the capillary pores of the mortar, but swells when moisture or harmful ions penetrate from the outside, and the capillary pores. It plays the role of blocking.

スチレン−エチレンビニルバーサテイトエマルジョンは、市販品を購入して使用することができ、市販品としては、例えば、ドイツのＢＡＳＦ社のアクロナールＳ５５９（Ａｃｒｏｎａｌ Ｓ５５９）またはＣｌａｒｉａｎｔ社のエルディーエム６８８０（ＬＤＭ６８８０）などを挙げることができる。   The styrene-ethylene vinyl versatate emulsion can be used by purchasing a commercial product. Examples of the commercial product include BASF AG's Acronal S559 (Acronal S559) or Clariant's LM 6880 (LDM6880). Can be mentioned.

前記添加剤としては、増粘剤、消泡剤、分散剤、接着剤、防腐剤などからなる群より選択される１種以上のものを挙げることができ、前記添加剤は、組成物の総重量に対して、０．１−１０重量％で含まれ得る。   Examples of the additive include one or more selected from the group consisting of thickeners, antifoaming agents, dispersants, adhesives, preservatives, and the like. It may be included at 0.1-10% by weight with respect to the weight.

特に、添加剤として、組成物の総重量に対して、メチルセルロース系増粘剤０．１−３重量％、シリコーン系消泡剤０．０２−２重量％、およびメラミン−スルホネート系ホルムアルデヒド縮合物分散剤０．１−５重量％が含まれる場合、ポリマーセメントモルタル組成物がより好ましい物性を示す。   In particular, as additives, 0.1-3% by weight of a methylcellulose thickener, 0.02-2% by weight of a silicone antifoam, and a melamine-sulfonate formaldehyde condensate dispersion based on the total weight of the composition When 0.1-5 weight% of an agent is contained, a polymer cement mortar composition shows a more preferable physical property.

［実施例］

Hereinafter, the present invention will be described in more detail through examples.

しかし、下記の実施例は本発明をより具体的に説明するためのものであって、本発明の範囲が下記の実施例によって限定されるものではない。下記の実施例は、本発明の範囲内で当業者によって適切に修正、変更可能である。   However, the following examples are for explaining the present invention more specifically, and the scope of the present invention is not limited by the following examples. The following embodiments can be appropriately modified and changed by those skilled in the art within the scope of the present invention.

速硬性セメント１６０ｋｇ、普通セメント２４０ｋｇ、粉末度８０〜１００メッシュが９５％でシリカ含有量が９０％以上の珪砂３２０ｋｇ、硫酸ナトリウム６０ｋｇ、スチレン−エチレンビニルバーサテイトエマルジョン（ドイツのＢＡＳＦ社のアクロナールＳ５５９）２００ｋｇ、ステアリン酸塩２０ｋｇ、メチルセルロース系増粘剤１．２ｋｇ、シリコーン系消泡剤０．８ｋｇ、およびメラミン−スルホネートホルムアルデヒド縮合物界分散剤２ｋｇを混合し、ポリマーセメントモルタル組成物１０００ｋｇを製造した。   Fast-hardening cement 160 kg, ordinary cement 240 kg, silica sand 320 kg with a fineness of 80-100 mesh and silica content of 90% or more, sodium sulfate 60 kg, styrene-ethylene vinyl versatate emulsion (Acronal S559 from BASF, Germany) 200 kg, stearate 20 kg, methylcellulose thickener 1.2 kg, silicone antifoam 0.8 kg, and melamine-sulfonate formaldehyde condensate boundary dispersant 2 kg were mixed to produce 1000 kg of a polymer cement mortar composition.

ポリマーセメントモルタル組成物を水と混合（水：モルタル組成物＝２２：１００の割合）した状態のモルタルと、市販製品（表面仕上げ用セメントモルタル）を水と混合（水：モルタル＝２２：１００の割合）した状態のモルタルとを、それぞれ断熱板試験片に５ｍｍ厚さに塗布した後、物性を比較した。試験結果は下記表１に示した。   A polymer mortar composition mixed with water (water: mortar composition = 22: 100 ratio) and a commercial product (surface finish cement mortar) mixed with water (water: mortar = 22: 100). The mortar in the state of the ratio was applied to a heat insulating plate test piece to a thickness of 5 mm, and the physical properties were compared. The test results are shown in Table 1 below.

Figure 0005451942
Figure 0005451942

前記表１から確認されるように、本発明にかかる断熱パネルに適用されるポリマーセメントモルタル組成物は、既存に用いられている市販製品に比べて、圧縮強度および付着強度が顕著に優れ、亀裂発生もなく、極めて優れた防水性（吸水率）を示した。   As can be seen from Table 1, the polymer cement mortar composition applied to the heat insulation panel according to the present invention is significantly superior in compressive strength and adhesion strength compared to commercially available products that have been used, and cracks are present. There was no occurrence and extremely excellent waterproofness (water absorption) was shown.

また、硬化時間が短く、パネルまたはボードなどの製品に適用する場合、製造時間の短縮が可能であることが分かる。   Also, it can be seen that the curing time is short and the manufacturing time can be shortened when applied to products such as panels or boards.

以上は、本発明によって実現できる好ましい実施例の一部について説明したのに過ぎないので、周知のように、本発明の範囲は上記の実施例に限定されて解釈されてはならず、上述した本発明の技術的思想とその根本を同じくする技術的思想はすべて本発明の範囲に含まれると見なすべきである。   The foregoing is only a description of some of the preferred embodiments that can be realized by the present invention, and as is well known, the scope of the present invention should not be construed as limited to the above-described embodiments, but has been described above. All technical ideas that are the same as the technical idea of the present invention should be considered to be included in the scope of the present invention.
