Description

本発明は造形用モルタル、特に建造物の内壁や外壁への造形や、遊園地、博物館等の人工の岩山の造形に適した内装用もしくは外装用の造形用モルタルに関する。 The present invention relates to a mortar for modeling, and more particularly, to a mortar for interior or exterior suitable for modeling an inner wall or an outer wall of a building, or modeling an artificial rocky mountain such as an amusement park or a museum.

特殊な造形、例えば建造物の内壁や外壁への造形や、遊園地、博物館等の人工の岩山の造形等の表面をモルタル仕上げする場合、従来は主として、普通ポルトランドセメントから成るモルタルが用いられていた。
しかしながら、普通ポルトランドセメント等による従来のモルタルは、一回のコテ塗りでは2〜3cm厚にしか盛り付けることができず、厚塗りを行うためには、ある程度乾いてからコテ塗りを繰り返すという手間がかかり、さらに硬化も速く、モルタル施工後にコテによる造形処理を行うための充分な硬化時間があるとはいえない。
In the case of mortar finishing for special modeling, for example, modeling on the inner and outer walls of buildings, and modeling of artificial rocks in amusement parks, museums, etc., mortar made of ordinary Portland cement has been used. It was.
However, conventional mortar made of ordinary Portland cement, etc., can only be applied to a thickness of 2 to 3 cm with a single trowel coating, and it takes time and effort to repeat the trowel coating after it has dried to some extent. Further, the curing is faster, and it cannot be said that there is a sufficient curing time for performing a shaping process with a trowel after mortar construction.

そこで、特開昭63−194687号公報(特許文献1参照)に示すような、セメント、消石灰、炭酸カルシウム微粉、混和剤、砂を組み合わせて所定量の水で混和した組成とし、なおかつ[セメント+消石灰+炭酸カルシウム微粉+混和剤]:砂=1:1.5〜1:2.5、の比からなる混合組成物で構成したことを特徴とする造形用モルタルが提案されている。 Therefore, as shown in JP-A-63-194687 (see Patent Document 1), a composition in which cement, slaked lime, calcium carbonate fine powder, admixture and sand are combined and mixed with a predetermined amount of water, and [Cement + There has been proposed a molding mortar characterized by comprising a mixed composition having a ratio of slaked lime + calcium carbonate fine powder + admixture]: sand = 1: 1.5 to 1: 2.5.

特開昭63−194687号公報Japanese Unexamined Patent Publication No. 63-194687

とはいえ、上記先行技術の造形用モルタルも、配合比が[セメント+消石灰+炭酸カルシウム微粉+混和剤]:砂=1:1.5〜1:2.5であるため、厚塗りすると非常に重くなってしまい、使用する場所や壁面の素材が限られたり、工期が長い上に造形を行う作業者の負担が非常に重いものになってしまうという問題があった。
そこでこの発明は、厚塗りしてもあまり重くなることがなく、使用する場所や壁面の素材にもほとんど制約なく使用することができ、短い工期で造形を行う作業者の負担を大幅に軽減することができる内装用もしくは外装用の造形用モルタルを提供しようとするものである。
However, since the blending ratio of the above prior art molding mortar is [cement + slaked lime + calcium carbonate fine powder + admixture]: sand = 1: 1.5 to 1: 2.5, There is a problem that the place of use and the material of the wall surface are limited, the construction period is long, and the burden on the worker who performs the modeling becomes very heavy.
Therefore, the present invention does not become too heavy even if it is thickly applied, and can be used with almost no restrictions on the place of use and the material of the wall surface, greatly reducing the burden on the operator who performs modeling in a short construction period An object of the present invention is to provide a molding mortar for interior or exterior use.

そこで本発明者らは従来の上述の問題点を解決し、満足のゆく施工性を示し、しかも低コストの造形用モルタルを得るべく研究を重ねた結果、下記のような素材を一定の割合で配合することにより、安価でしかも造形用として優れた性質を有する造形用モルタルが得られることを見出だし、本発明を完成した。

以下、本発明の内装用もしくは外装用の造形用モルタルの各成分についてさらに詳しく説明する。
内装用)
<結合剤>
無水石膏:本発明に使用する結合剤としては、内装用には無水石膏(CaSO4)が使用される。この無水石膏(CaSO4)は結晶水を持たない硫酸カルシウムで、可溶性無水石膏(III型無水石膏)と不溶性無水石膏(II型無水石膏)がある。半水石膏を加熱(180℃〜190℃)して得られる可溶性無水石膏は、空気中の水分を吸着して半水石膏に戻る。一方、不溶性無水石膏は天然に存在するが、二水石膏を300℃〜700℃で焼成することでも得られる。不溶性無水石膏は水を加えても容易に水和反応しないが、凝結促進剤を加えて硬化させることができる。配合量は後述の炭酸カルシウム微粉とほぼ等量、35〜50重量部を使用することが望ましい。
無水石膏(CaSO4)のメリットとしては、加熱、圧縮などの操作が不要で作業が容易に行え、短時間で成型ができること、適度の膨張があり、型が精密にとれること、成型体の安定が高く、乾燥・吸湿による変形がなく、人体に無害で安全であることが挙げられる。
Hereinafter, each component of the molding mortar for interior use or exterior use of the present invention will be described in more detail.
For interior)
<Binder>
Anhydrous gypsum: As a binder used in the present invention, anhydrous gypsum (CaSO4) is used for interior use. This anhydrous gypsum (CaSO4) is calcium sulfate without crystal water, and there are soluble anhydrous gypsum (type III anhydrous gypsum) and insoluble anhydrous gypsum (type II anhydrous gypsum). Soluble anhydrous gypsum obtained by heating hemihydrate gypsum (180 ° C. to 190 ° C.) adsorbs moisture in the air and returns to hemihydrate gypsum. On the other hand, insoluble anhydrous gypsum exists naturally, but it can also be obtained by baking dihydrate gypsum at 300 ° C to 700 ° C. Insoluble anhydrous gypsum does not readily hydrate when water is added, but can be cured by adding a setting accelerator. It is desirable that the blending amount is approximately equal to the calcium carbonate fine powder described later and 35 to 50 parts by weight.
The advantages of anhydrous gypsum (CaSO4) are that operations such as heating and compression are not required, work can be done easily, molding can be done in a short time, there is moderate expansion, the mold can be taken precisely, and the molded body is stable. It is high, is free from deformation due to drying and moisture absorption, is harmless to the human body and safe.

<混和剤>
炭酸カルシウム:炭酸カルシウムは、コテ塗り作業性の向上の目的で使用され、微粉状のものを使用し、配合量は内装用では35〜50重量部である。配合量が35重量部未満では、コテ塗り作業性が悪くなるので好ましくなく、50重量部を越えるとコテ塗り作業性が悪くなるので好ましくない。
カチオン系粉末樹脂:カチオン系粉末樹脂を添加することにより、各種下地に対して抜群の付着力を発揮する造形用モルタルとなる。配合量は内装用では5〜10重量部である。
珪藻土:珪藻土は、高い耐火・断熱性能を有している。また耐薬品性・吸液性や軽量という特徴を活かし、各種充填材に使用されている。また珪藻土を混合することにより、塗料のつや消し効果を得ることができる。配合量は内装用では5〜10重量部である。
水溶性セルロースエーテル:セルロースエーテルはセルロースに含まれるヒドロキシ基をエーテルに変換したものである。セルロースは自然界に存在する高分子であり、一部の有機溶媒には溶解するものの、一般的な溶媒である水には不溶である。これは、セルロースの構成単位であるグルコース環にヒドロキシ基が存在し、隣接するヒドロキシ基との間に水素結合を生じて結晶化するために水和を阻害するからである。
このヒドロキシ基の水素原子をメチル基などで置換して水素結合の生成を阻害することにより水和が行なわれるようになり、水溶性が得られる。この時、グルコース環とその置換基の間にエーテル結合が生じるため、このような結合様式を有するセルロース誘導体を総称してセルロースエーテルと呼ぶ。
具体例としては、例えば、メチルセルロース(MC)、メチルヒドロキシエチルセルロース(MHEC)、メチルヒドロキシプロピルセルロース(MHPC)、ヒドロキシエチルセルロース(HEC)、エチルヒドロキシエチルセルロース(EHEC)等が挙げられる。市販の水溶性セルロースエーテル類を用いることも可能であり、市販品としては、例えば、ダイセルファインケム社製のセルブレン、信越化学社製のメトローズやhi≡メトローズ、松本油脂製薬社製のマーポローズ、ダウ社製のメトセル、アクゾノーベル社製のベルモコール、ハークレス社のアクアロン等が挙げられる。
この水溶性セルロースエーテルは、セメントモルタルの亀裂の発生、接着力、強度の低下を防ぐなど、建材の品質を向上、施工・作業性を改善するものである。配合量は内装用では0.1〜0.3重量部である。
<Admixture>
Calcium carbonate: Calcium carbonate is used for the purpose of improving the ironing workability, and is finely powdered. The amount is 35 to 50 parts by weight for interior use. When the blending amount is less than 35 parts by weight, the ironing workability is deteriorated, which is not preferable. When the amount exceeds 50 parts by weight, the ironing workability is deteriorated.
Cationic powder resin: By adding a cationic powder resin, it becomes a modeling mortar that exhibits outstanding adhesion to various bases. A compounding quantity is 5-10 weight part for interior use.
Diatomaceous earth: Diatomaceous earth has high fire resistance and heat insulation performance. In addition, it is used for various fillers, taking advantage of its chemical resistance, liquid absorption and light weight. Moreover, the matte effect of a coating material can be acquired by mixing diatomaceous earth. A compounding quantity is 5-10 weight part for interior use.
Water-soluble cellulose ether: Cellulose ether is obtained by converting a hydroxy group contained in cellulose into ether. Cellulose is a polymer that exists in nature and dissolves in some organic solvents, but is insoluble in water, which is a common solvent. This is because a hydroxyl group exists in the glucose ring, which is a constituent unit of cellulose, and a hydration is inhibited because a hydrogen bond is formed between adjacent hydroxyl groups to cause crystallization.
Hydration is carried out by substituting the hydrogen atom of the hydroxy group with a methyl group to inhibit the formation of hydrogen bonds, and water solubility is obtained. At this time, since an ether bond is generated between the glucose ring and its substituent, cellulose derivatives having such a bonding mode are collectively referred to as cellulose ether.
Specific examples include methyl cellulose (MC), methyl hydroxyethyl cellulose (MHEC), methyl hydroxypropyl cellulose (MHPC), hydroxyethyl cellulose (HEC), ethyl hydroxyethyl cellulose (EHEC), and the like. Commercially available water-soluble cellulose ethers can also be used, and examples of commercially available products include Daicel Finechem's Cellbrene, Shin-Etsu Chemical's Metroles and hi≡Metroze, Matsumoto Yushi Seiyaku Marporose, Dow Methocel made by Akzo Nobel, Vermocol made by Akzo Nobel, Aqualon made by Hercules, and the like.
This water-soluble cellulose ether improves the quality of building materials and improves the workability and workability, such as preventing cracking of cement mortar, reducing adhesive strength and strength. A compounding quantity is 0.1-0.3 weight part for interior use.

増粘剤(ポリアクリル酸ナトリウム):この増粘剤の持つ高い吸水性は、親水性のカルボキシル基を有し、かつ網目構造の中に多数の水分子を取り込んでゲル構造を作ることによる。配合量は内装用では0.01〜0.05重量部である。
消泡剤:消泡剤とは、通常、消泡剤とされるものであれば特に限定されることはない。例えば、疎水性シリカ、金属石鹸系、アマイド系、変性シリコーン系、シリコーンコンパウンド系、ポリエーテル系、エマルション系、粉末系などがある。例えば、変性シリコーン系消泡剤として、信越化学製のシリコーンKM80(商品名)、シリコーンコンパウンド系消泡剤として、サンノプコ(株)製のSNデフォーマー121N(商品名)、ポリエーテル系消泡剤として、サンノプコ(株)製のSNデフォーマーPC(商品名)、エマルション系消泡剤として、サンノプコ(株)製のノプコKF−99(商品名)、粉末系消泡剤として、サンノプコ(株)製のSNデフォーマー14−HP(商品名)等を例示できる。配合量は内装用では0.5〜2.0重量部である。
軽量骨材:軽量骨材としては火山性細粒ガラス質凝灰岩(シルト)を高温で加熱発泡させた中空軽量で微細な球状の発泡体、例えばマールライト(商品名、丸中白土株式会社製)が好適に使用できる。配合量は内装用では15〜35重量部である。
硬化遅延剤:硬化遅延剤としてクエン酸や酒石酸を使用しているので、硬化速度を遅らせることができる。配合量は内装用では0.02〜0.08である。
なお水の配合割合は、水:水/造形用モルタル比で0.40以下である。
Thickener (sodium polyacrylate): The high water absorption property of this thickener is due to the formation of a gel structure having a hydrophilic carboxyl group and incorporating a large number of water molecules into the network structure. A compounding quantity is 0.01-0.05 weight part for interior use.
Antifoaming agent: The antifoaming agent is not particularly limited as long as it is generally used as an antifoaming agent. Examples include hydrophobic silica, metal soap, amide, modified silicone, silicone compound, polyether, emulsion, and powder. For example, as a modified silicone-based antifoaming agent, Shin-Etsu Chemical's silicone KM80 (trade name), as a silicone compound-based antifoaming agent, as a SN deformer 121N (trade name) manufactured by San Nopco, as a polyether-based antifoaming agent SN Deformer PC (trade name) manufactured by San Nopco Co., Ltd., Nopco KF-99 (trade name) manufactured by San Nopco Co., Ltd. as an emulsion antifoaming agent, Sannopco Co., Ltd. manufactured by San Nopco Co., Ltd. SN deformer 14-HP (trade name) and the like can be exemplified. A compounding quantity is 0.5-2.0 weight part for interior use.
Lightweight aggregate: As a lightweight aggregate, a hollow lightweight fine spherical foam made by heating and foaming volcanic fine-grained vitreous tuff (silt) at a high temperature, such as Marlite (trade name, manufactured by Marunaka Shirato Co., Ltd.) Can be suitably used. A compounding quantity is 15-35 weight part for interior use.
Curing retarder: Since citric acid and tartaric acid are used as the retarder, the curing rate can be delayed. A compounding quantity is 0.02-0.08 for interior use.
The mixing ratio of water is 0.40 or less in terms of water: water / modeling mortar ratio.

以上の構成の内装用造形用モルタルでは以下のような効果を得ることができる。
A)石膏ベースで作業性が良い。

The interior molding mortar having the above configuration can obtain the following effects.
A) Workability is good with a gypsum base.
B) The specific gravity is about 60% compared to the conventional modeling mortar, and the burden on the ground can be reduced as well as workability.
C) Because it was lighter, it was possible to install it on plaster boards.
D) Since it contains diatomaceous earth and lightweight aggregate, it can have humidity control.
E) Each material is in the form of fine particles or powders that can be easily shaped (carved), and has good workability.
F) Since citric acid and tartaric acid are used as the curing retarder, it can be delayed to the former acceleration which is easy to form.

外装用)
<結合剤>
外装用の結合剤としては白セメントが好適に使用される。白セメント(White Portland cement)は、その名の通り純白色を特徴とするセメントである。白色普通ポルトランドセメント、ホワイトセメントなどとも呼ばれる。ポルトランドセメントの一種であり、白さを引き出すため、特に鉄分の含有量が減らされている。それ以外の基本的な性質は普通ポルトランドセメントとほぼ同じであるが、製造法がやや異なるため普通ポルトランドセメントよりも一般に高価である。
その配合量は、特に炭酸化を防ぎ、優れた耐久性を得るためには200〜300重量部とすることが好ましい。セメントの配合量が200重量部未満では貧調合のため耐久性の面で好ましくなく、逆に300重量部を越えると富調合のため硬化時間が短く、ひび割れが発生するなどの問題が生じるので好ましくない。
For exterior)
<Binder>
White cement is preferably used as the exterior binder. White Portland cement is a cement characterized by pure white as the name suggests. Also called white ordinary Portland cement, white cement. It is a kind of Portland cement and its iron content is especially reduced to bring out the whiteness. Other basic properties are almost the same as ordinary Portland cement, but are generally more expensive than ordinary Portland cement due to slightly different manufacturing methods.
The blending amount is particularly preferably 200 to 300 parts by weight in order to prevent carbonation and to obtain excellent durability. If the amount of cement is less than 200 parts by weight, it is not preferable in terms of durability because of poor blending. Conversely, if it exceeds 300 parts by weight, it is preferable because of the rich blending because the curing time is short and cracks occur. Absent.

<混和剤>
炭酸カルシウム:炭酸カルシウムは、コテ塗り作業性の向上の目的で使用され、微粉状のものを使用し、配合量は外装用では150〜230重量部である。配合量が150重量部未満では、コテ塗り作業性が悪くなるので好ましくなく、230重量部を越えるとコテ塗り作業性が悪くなるので好ましくない。
