【発明の属する技術分野】
本発明は、建築物の内装工事に際し、揮発性有機化合物（ＶＯＣ）等を発生させることがないため、施工中には作業者、施工後の居住者等の人体への悪影響がなく、しかもひび割れを発生することもない無機質建材用組成物、及びそれを用いた現場施工法、並びに無機質建材に関する。
【０００２】
【従来の技術】
従来より、多くの家屋やマンション等の内壁材や仕上げ材には、セメント、消石灰、石膏等の粉体固化材を用いた建築材料、或いは樹脂を固化材とする建築材料などが用いられている。
セメント等の粉体固化材を用いた建築材料は、水と十分に混練して塗工する方法であり、その配合によっては乾燥によるひび割れが発生するという問題があった。
また、樹脂を固化材とする建築材料は、樹脂を溶解するために有機溶剤を用いる必要があるため、その有機溶剤によっては以下のような問題を引き起こす場合がある。即ち、近年、多くの家屋やマンション等の内装壁及び床の仕上材等が原因で、目特に球結膜や鼻粘膜、喉粘膜等に異常刺激を感じたり、手足のしびれ、視力の低下、目眩、喘息、発熱、呼吸困難、吐き気等の種々の症状（化学物質過敏症）に見舞われ、アレルギー（ジンマシン、湿疹）、アトピー性皮膚炎（皮膚の赤斑）の悪化等の健康障害を引き起こす現象が増大している。これらは“シックハウス症候群”、或いは“シックビル症候群”と呼ばれ、社会的問題となっている。これらは、風通しの悪い高気密住宅における室内空気汚染や微生物汚染などが原因とされ、室内においてそれぞれ少量しか発生しない空気汚染質でも、住宅の気密性能が向上したことにより、人体に影響が及ぶ濃度になりがちで、前記の多くの健康障害が引き起こされているのである。既に指摘されている有機化合物としては、ホルムアルデヒド、アセトン、トルエン、フロン、トリクロロエチレン、ＴＣＥＰやＤＯＰ、塩化ビニルモノマー、スチレン、ホルムアルデヒド、キシレン、酢酸エチル等を挙げることができる。尚、前記セメント等の粉体固化材を用いた建築材料にも、前述のひび割れの解消等を目的として有機系混和剤として樹脂等が用いられている場合、同様な問題を生ずる。
さらに特に樹脂量の多い建築材料では、火災時に燃焼し、且つ有害ガスを発生するという問題もあった。
【０００３】
【発明が解決しようとする課題】
そこで、下地（コンクリート・石膏ボード等）に直接施工でき、十分に接着してひび割れ、剥がれ等の発生がなく、且つ揮発性有機化合物の有害物質を全く必要としない建築材料及び工法が嘱望されていた。
【０００４】
【課題を解決するための手段】
本発明は、上記に鑑み提案されたもので、天井材に用いる組成割合が、無機質硬化材１５〜６０ｗｔ％、無機質軽量多孔質骨材２０〜５０ｗｔ％、増粘材１〜３ｗｔ％、無機質顔料０．１〜０．５ｗｔ％からなる粉体１００重量部に対し、二酸化ケイ素及び炭酸塩を主成分とする無機系液体固化剤３〜７重量部を配合してなることを特徴とする無機質建材用組成物、及び無機質建材を提案するものである。
また、より高い接着性が要求される内壁材に用いる場合は、無機質硬化材６〜５０ｗｔ％、無機質粉体１０〜６０ｗｔ％、無機質骨材１０〜４０ｗｔ％、増粘材０．１〜０．５ｗｔ％、無機質顔料０．１〜０．５ｗｔ％からなる粉体１００重量部に対し、二酸化ケイ素及び炭酸塩を主成分とする無機系液体固化剤４０〜６０重量部を配合してなることを特徴とする無機質建材用組成物、及び無機質建材をも提案する。
さらに、天井材の現場施工に際し、コンクリートまたは石膏ボードの下地に、無機質硬化材１５〜６０ｗｔ％、無機質軽量多孔質骨材２０〜５０ｗｔ％、増粘材１〜３ｗｔ％、無機質顔料０．１〜０．５ｗｔ％からなる粉体１００重量部に対し、二酸化ケイ素及び炭酸塩を主成分とする無機系液体固化剤３〜７重量部を配合してなる組成物を塗工することを特徴とする無機質建材の現場施工法をも提案する。
また、内壁材の現場施工に際し、コンクリートまたは石膏ボードの下地に、無機質硬化材６〜５０ｗｔ％、無機質粉体１０〜６０ｗｔ％、無機質骨材１０〜４０ｗｔ％、増粘材０．１〜０．５ｗｔ％、無機質顔料０．１〜０．５ｗｔ％からなる粉体１００重量部に対し、二酸化ケイ素及び炭酸塩を主成分とする無機系液体固化剤４０〜６０重量部を配合してなる組成物を塗工することを特徴とする無機質建材の現場施工法をも提案する。
【０００５】
【発明の実施の形態】
まず、本発明、特に天井材、内壁材に用いるための各材料について以下に説明する。
【０００６】
本発明に用いる粉体は、無機質骨材、無機質硬化材、増粘剤、無機質顔料等であり、無機質骨材としては、珪藻土、珪藻土造粒物、珪藻土造粒焼成物、ゼオライト、ゼオライト焼成物等の湿度調整機能及び臭いを吸着する機能を持った骨材の他に珪砂、寒水石、天然砂、パーライト、雲母粉末、炭酸カルシウム等の無機質骨材等が使用でき、特に多孔質の軽量骨材は湿度調整機能の向上により大きな貢献を果たし、また軽量であるため特に天井材に用いるのに好適である。
この無機質骨材の配合割合は、例えば天井材では２０〜５０ｗｔ％、内壁材では１０〜４０ｗｔ％であるが、それ以下では臭いを吸着する機能及び湿度調整機能が低下すると同時に美観（意匠）上の問題があり、それ以上になると施工性が悪化する。
【０００７】
無機質硬化材としては、消石灰、ドロマイトプラスター、せっこう、セメント等を使用できる。尚、消石灰やドロマイトプラスターは、ミョウバン石或いは無水硫酸アルミニウムと併用することにより、自硬性のプラスターができることが知られている。
この無機質硬化材の配合割合は、例えば天井材では１５〜６０ｗｔ％、内壁材では６〜５０ｗｔ％であるが、それ以下では表面強度が弱く、それ以上になると湿度調整機能が低下する。
【０００８】
増粘剤としては、メチルセルロース、ヒドロキシプロピルメチルセルロース、ヒドロキシエチルメチルセルロース、エチルヒドロキシエチルセルロース、ヒドロキシエチルセルロース、ポリビニルアルコール等の合成高分子物質或いは澱粉類、海藻類、ゼラチン類、アルギン酸ソーダ等の天然高分子物質から選ばれる１種以上の水溶性増粘剤を使用することができる。この水溶性増粘剤は、こて塗り作業性を向上する効果を果たすが、同時に接着性を向上する効果を果たすものも多い。また、合成有機材料よりも植物等から得られた天然有機物を用いることが望ましい。
この増粘剤の配合割合は、例えば天井材では１〜３ｗｔ％、内壁材では０．１〜０．５ｗｔ％であるが、それ以下では施工性が悪く、それ以上でも作業性が悪くなり、加えて仕上精度も悪くなり、さらに施工後の乾燥性も悪くなる。
【０００９】
また、内壁材に配合する無機質粉体としては、石灰、酸化チタン等を使用できる。
この無機質粉体の配合割合は、内壁材では１０〜６０ｗｔ％であるが、それ以下では臭いを吸着する機能及び湿度調整機能が低下し、それ以上では施工性が悪化する。
【００１０】
本発明に用いる無機系液体固化剤は、二酸化ケイ素及び炭酸塩を主成分とするものである。表１にこの無機系液体固化剤のｐＨ及び主要含有イオンを示す。
【表１】
本発明において、この無機系液体固化剤の配合割合は、例えば天井材では前記粉体１００重量部に対して３〜７重量部、内壁材では４０〜６０重量部であるが、それ以下では乾燥時のひび割れ防止効果が小さく、それ以上では湿度調整機能が低下する。
【００１１】
この無機系液体固化剤を用いることにより、必ずしも消石灰、せっこう、セメント等の無機系硬化材を用いる必要はない。しかし、併用した場合には詳細は不明であるが或る種の相乗的作用により、ワレが発生することなく強固な建築材料とすることができる。
【００１２】
また、流動性の付与及び混練り水を減少させるために必要に応じ、高性能減水剤を使用しても良く、高性能減水剤としては、ナフタリンスルホン酸縮合物塩、スルホン化メラミン縮合物塩、スチロールメラミン縮合物塩等を使用することができる。さらに、水分散性、水溶解性を向上するために、ステアリン酸カルシウム、ステアリン酸亜鉛、ステアリン酸アルミニウム等の金属石鹸を加えて疎水性にすると、徐々に分散して塊等を作らずに速やかに分散混合することができる。また、粘性の改良のためパルプ質、セピオライト等の繊維材料等を加えるようにしても良い。
【００１３】
これらの各成分から構成される本発明の無機質建材組成物は、コンクリートや石膏ボード等の下地に、直接施工することができ、十分に接着してひび割れや剥がれ、膨れ等の不良を発生することがない。また、有機溶剤を用いないので、施工作業者並びに施工後の居住者等の人体に悪影響を与えることがない。
そのため、本発明により得られる無機質建材は、所謂健康住宅用の建築内装材料として好適に使用することができる。しかもこの無機質建材は、無機質材料のみで構成されるため、火災等においても燃焼したり、有害ガスを発生することがない。

The present invention relates to a composition for an inorganic building material that does not generate odor, an on-site construction method using the same, and an inorganic building material.
[0002]
[Prior art]
Conventionally, building materials using powder solidifying materials such as cement, slaked lime, and plaster, or building materials using resin as a solidifying material have been used for inner walls and finishing materials of many houses and apartments. .
Building materials using a powder solidifying material such as cement are a method in which they are sufficiently kneaded with water and applied, and there is a problem that cracking due to drying occurs depending on the formulation.
Moreover, since it is necessary to use the organic solvent in order to melt | dissolve resin, the building material which uses resin as a solidification material may cause the following problems depending on the organic solvent. That is, in recent years, due to the finishing materials of interior walls and floors of many houses and condominiums, etc., the eyes, especially the bulbar conjunctiva, nasal mucosa, throat mucosa, etc. feel abnormal irritation, limb numbness, decreased visual acuity, dizziness Phenomena that cause various health problems such as asthma, fever, dyspnea, nausea (chemical hypersensitivity), worsening allergies (gin machine, eczema), atopic dermatitis (skin erythema) Has increased. These are called “sick house syndrome” or “sick building syndrome” and are a social problem. These are caused by indoor air pollution and microbial contamination in highly airtight houses with poor ventilation, and even air pollutants that generate only a small amount in the room are affected by the improvement in the airtight performance of the house, which affects the human body. Many of these health problems have been caused. Examples of organic compounds that have already been pointed out include formaldehyde, acetone, toluene, freon, trichlorethylene, TCEP and DOP, vinyl chloride monomer, styrene, formaldehyde, xylene, and ethyl acetate. In addition, the same problem occurs when a resin or the like is used as an organic admixture in a building material using a powder solidifying material such as cement as described above for the purpose of eliminating the above-mentioned cracks.
Furthermore, in the case of building materials having a particularly large amount of resin, there is a problem in that they burn in a fire and generate harmful gases.
[0003]
[Problems to be solved by the invention]
Therefore, building materials and construction methods that can be directly applied to the base (concrete, gypsum board, etc.), do not generate cracks or peel off sufficiently, and do not require any harmful substances of volatile organic compounds are desired. It was.

[0005]
DETAILED DESCRIPTION OF THE INVENTION
First, each material used for this invention, especially a ceiling material and an inner wall material is demonstrated below.
[0006]
The powder used in the present invention is an inorganic aggregate, an inorganic hardener, a thickener, an inorganic pigment, and the like. As the inorganic aggregate, diatomaceous earth, diatomaceous earth granulated material, diatomaceous earth granulated material, zeolite, zeolite calcined material In addition to aggregates that have humidity adjustment functions such as moisture adsorbing function, mineral aggregates such as quartz sand, cryolite, natural sand, perlite, mica powder, calcium carbonate, etc. can be used, especially porous lightweight bone The material contributes greatly by improving the humidity adjusting function and is particularly suitable for use as a ceiling material because of its light weight.
The blending ratio of the inorganic aggregate is, for example, 20 to 50 wt% for the ceiling material and 10 to 40 wt% for the inner wall material. However, below that, the function of adsorbing odor and the humidity adjusting function are lowered and at the same time the aesthetics (design) There is a problem, and if it is more than that, workability deteriorates.
[0007]
As the inorganic hardener, slaked lime, dolomite plaster, gypsum, cement and the like can be used. In addition, it is known that slaked lime and dolomite plaster can form a self-hardening plaster when used in combination with alumite or anhydrous aluminum sulfate.
The blending ratio of the inorganic hardening material is, for example, 15 to 60 wt% for the ceiling material and 6 to 50 wt% for the inner wall material, but the surface strength is weak below this, and the humidity adjusting function decreases when it exceeds this.
[0008]
Thickeners include synthetic polymer materials such as methylcellulose, hydroxypropylmethylcellulose, hydroxyethylmethylcellulose, ethylhydroxyethylcellulose, hydroxyethylcellulose, and polyvinyl alcohol, or natural polymer materials such as starches, seaweeds, gelatins, and sodium alginate. One or more water-soluble thickeners selected can be used. This water-soluble thickener has the effect of improving the troweling workability, but many of them also have the effect of improving the adhesiveness. Moreover, it is desirable to use natural organic substances obtained from plants or the like rather than synthetic organic materials.
The blending ratio of this thickener is, for example, 1 to 3 wt% for the ceiling material and 0.1 to 0.5 wt% for the inner wall material, but the workability is poor below this, and the workability is worse even above that, In addition, the finishing accuracy is deteriorated and the drying property after construction is also deteriorated.
[0009]
Moreover, lime, titanium oxide, etc. can be used as an inorganic powder mix | blended with an inner wall material.
The blending ratio of the inorganic powder is 10 to 60 wt% for the inner wall material, but if it is less than that, the function of adsorbing odors and the humidity adjusting function are lowered, and if it is more, the workability is deteriorated.
[0010]
The inorganic liquid solidifying agent used in the present invention is mainly composed of silicon dioxide and carbonate. Table 1 shows the pH and main ions contained in this inorganic liquid solidifying agent.
[Table 1]
In the present invention, the blending ratio of the inorganic liquid solidifying agent is, for example, 3 to 7 parts by weight for the ceiling material with respect to 100 parts by weight of the powder, and 40 to 60 parts by weight for the inner wall material. The effect of preventing cracking at the time is small, and the humidity adjustment function is lowered above this.
[0011]
By using this inorganic liquid solidifying agent, it is not always necessary to use an inorganic hardening material such as slaked lime, gypsum, or cement. However, when it is used in combination, the details are unknown, but it can be made a strong building material without cracking due to a certain synergistic action.
[0012]
Further, in order to impart fluidity and reduce kneading water, a high performance water reducing agent may be used as necessary. As the high performance water reducing agent, naphthalene sulfonic acid condensate salt, sulfonated melamine condensate salt A styrene melamine condensate salt or the like can be used. Furthermore, in order to improve water dispersibility and water solubility, by adding a metal soap such as calcium stearate, zinc stearate, and aluminum stearate to make it hydrophobic, it is gradually dispersed without forming a lump etc. Can be dispersed and mixed. Further, for improving the viscosity, fiber materials such as pulp and sepiolite may be added.
[0013]
The inorganic building material composition of the present invention composed of each of these components can be directly applied to a base such as concrete or gypsum board, and sufficiently adheres to cause defects such as cracking, peeling and swelling. There is no. Moreover, since an organic solvent is not used, it does not adversely affect human bodies such as construction workers and residents after construction.
Therefore, the inorganic building material obtained by the present invention can be suitably used as a so-called building interior material for a healthy house. And since this inorganic building material is comprised only with an inorganic material, it does not burn in a fire etc. or generate | occur | produces a harmful gas.
[0014]
【Example】
[Examples 1-4, Comparative Examples 1-3]
Using the inorganic liquid solidifying agent shown in Table 2, Examples 1 to 4 of the inorganic building material composition of the present invention were prepared at the composition ratio shown in Table 3. Moreover, the composition of Comparative Examples 1-3 which does not mix | blend an inorganic type liquid solidifying agent at all was prepared similarly, and it used for the following tests.
In addition, Example 1, 2 is a specification for ceilings, and Example 3, 4 is the mixing | blending of an inner wall material specification. Comparative Example 1 is exactly the same as Examples 1 and 2 except that no inorganic liquid solidifying agent is added, and Comparative Example 3 is an ethylene vinyl acetate synthetic resin emulsion added thereto. Comparative Example 2 is exactly the same as Example 3 and 4 except that no inorganic liquid solidifying agent is added.
[Table 2]
[Adhesion test]
The adhesiveness test was implemented about the inorganic building material composition of Examples 1-4 of the composition ratio shown in the said Table 3, and the composition of Comparative Examples 1-3. The results are shown in Table 4.
・ Test method Apply a specified amount of material to a 70 x 70 x 20 mm mortar base plate and let it stand in the curing room for 14 days, then attach a steel jig for tensioning by epoxy bonding, and reach the substrate around the jig After making the incision reached, the adhesion strength was measured with a universal testing machine (Autograph AG-5000C manufactured by Shimadzu Corporation).
・ Test results [Table 4]
In addition, in the compositions of Examples 3 and 4 which were blended according to the specification of the inner wall material, an extremely high adhesion strength of 0.62 and 0.73 N / mm 2 could be obtained, but an inorganic liquid solidifying agent was blended. In Comparative Example 2, the adhesion strength was only about half of that, and this level of adhesion strength might cause a problem in practicality as an inner wall material.
[0016]
[Alkali resistance test and dew resistance test]
The alkali resistance test and the dew proof test were carried out on the inorganic building material compositions of Examples 1 and 2 and the compositions of Comparative Examples 1 and 3 having the composition ratios shown in Table 3. The results are shown in Table 5.
-Test method The alkali resistance C method by the lightweight aggregate finish coating material of JIS A6909 (architectural finishing coating material), and the dew-proofing test were implemented.
・ Test results [Table 5]
