Description
本発明は、モルタルに混和し、コテ塗り作業性特にコテ伸び、コテ離れ、ダレにくさ、仕上げ美観を改善するために用いる左官モルタル用混和材、それを配合したモルタル組成物、及びこれを用いた施工方法に関する。 The present invention relates to a plastering mortar admixture used to improve the workability of troweling, especially trowel elongation, detachment, sag, and finishing aesthetics, and a mortar composition containing the same. It relates to the construction method.
左官モルタル用混和材は、コテ伸び、コテ滑り、コテ離れ等のコテ塗り作業性を改善すること、ダレを防止すること、仕上がり面をよりきれいにすること等を目的として用いられる。
従来は、左官モルタル用混和材として石綿が多用されており、これはコテ塗り作業性、ダレ防止、仕上がり等の面で非常に優れていた。しかし、人体に対する有害性の観点から、その利用が規制されるようになってきた。その後、蛇紋岩が、石綿の代替材料として広く使用されるようになり、このものもモルタルの作業性改善効果は優れていた。しかし、近年、蛇紋岩の多くにクリソタイルが含有しているという見方が公的に示され、これらも規制されることとなった。これに対し、有害性の低い石綿代替材料として、「水溶性ポリウレタン樹脂などの有機系混和剤」（特許文献１参照）、「石灰石粉末からなるセメント混和材」（特許文献２参照）、「石綿又は石綿含有蛇紋岩を焼成した混和材」（特許文献３参照）、などが提案されている。しかし、これらの石綿代替材料は、モルタルの作業性改善効果が十分ではなく、石綿や蛇紋岩の性能レベルに到達していないのが現状である。
The admixture for plastering mortar is used for the purpose of improving troweling workability such as trowel elongation, trowel slip, trowel separation, etc., preventing sagging, and making the finished surface cleaner.
Conventionally, asbestos has been widely used as an admixture for plastering mortar, and this was extremely excellent in terms of troweling workability, prevention of sagging, and finishing. However, its use has been regulated from the viewpoint of harm to the human body. After that, serpentine became widely used as an alternative material for asbestos, and this also had an excellent effect on improving the workability of mortar. However, in recent years, the view that chrysotile is contained in many serpentine has been publicly announced, and these have also been regulated. On the other hand, as an asbestos substitute material with low toxicity, “organic admixture such as water-soluble polyurethane resin” (see Patent Document 1), “cement admixture made of limestone powder” (see Patent Document 2), “asbestos” Or the admixture which baked the asbestos containing serpentine "(refer patent document 3), etc. are proposed. However, these asbestos substitute materials are not sufficiently effective in improving the workability of mortar and have not reached the performance level of asbestos and serpentine.
本発明は、安価であり、入手しやすく、且つ人体に対する有害性が低く、モルタルの作業性改善効果が石綿や蛇紋岩と同等あるいはそれ以上のレベルである左官モルタル用混和材の開発及びそれを配合したモルタル組成物を提供することを目的としている。 The present invention is a development of an admixture for plastering mortar that is inexpensive, easy to obtain, has low harmfulness to the human body, and has a workability improvement effect of mortar equivalent to or higher than that of asbestos and serpentine. The object is to provide a blended mortar composition.
本発明者は、上記課題を解決するために鋭意研究した結果、特定の粘土鉱物を含有し特定の粒子径を有したクレーと、水溶性高分子増粘剤を組み合わせることにより得た左官モルタル用混和材を使用することにより、モルタルの作業性が大きく改善できることを見出し、本発明に至った。 As a result of diligent research to solve the above problems, the present inventor has found that clay containing a specific clay mineral and having a specific particle diameter and a plaster mortar obtained by combining a water-soluble polymer thickener. It has been found that the workability of mortar can be greatly improved by using an admixture, and the present invention has been achieved.

［２］ 水溶性高分子増粘剤が、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、ヒドロキシエチルセルロース、ヒドロキシエチルエチルセルロース、キサンタンガム、グアーガム、カラギーナン、アルギン酸ソーダ、カゼイン、ポリオチレンオキサイド、ポリビニルアルコール、水溶性ポリウレタンから選ばれた１種または２種以上である上記［１］に記載の左官モルタル用混和材、
That is, the present invention

[2] The water-soluble polymer thickener was selected from methylcellulose, hydroxypropylmethylcellulose, hydroxyethylcellulose, hydroxyethylethylcellulose, xanthan gum, guar gum, carrageenan, sodium alginate, casein, polyoxylene oxide, polyvinyl alcohol, and water-soluble polyurethane. The admixture for plastering mortar according to the above [1], which is one type or two or more types,
［３］ 上記［１］に記載の左官モルタル用混和材に対し、さらに珪砂、石灰石微粉末、フライアッシュ、高炉スラグ粉末、シラスバルーン、パーライトからなる群から選ばれた１種または２種以上の無機物質を左官モルタル用混和材１００重量部に対し３００重量部を超えない範囲で配合してなる上記［１］または［２］に記載の左官モルタル用混和材、
［４］ 上記［１］〜［３］のいずれかに記載の左官モルタル用混和材を、モルタル組成物（水配合前の重量）１００重量部に対し０．５〜１０重量部を含む左官用モルタル組成物、

[3] One or more selected from the group consisting of silica sand, fine limestone powder, fly ash, blast furnace slag powder, shirasu balloon, and pearlite with respect to the admixture for plastering mortar described in [1] above. The admixture for plastering mortar according to the above [1] or [2], wherein an inorganic substance is blended in an amount not exceeding 300 parts by weight with respect to 100 parts by weight of the admixture for plastering mortar,
[4] The plastering mortar admixture according to any one of [1] to [3] above, containing 0.5 to 10 parts by weight with respect to 100 parts by weight of the mortar composition (weight before mixing with water). Mortar composition,
[5] A plastering method characterized by using the mortar composition for plastering according to [4] above, and [6] a building or building using the mortar composition for plastering according to [4] above By solving this problem, the above problems were solved.
実施例の左官モルタル用混和材は、プレーンモルタルに対しコテ塗り作業性が良くなり「コテ伸び」「コテ滑り」「コテ離れ」「ダレにくさ」「仕上げ美観」が大きく改善された。また、市販品Ｂ（蛇紋岩系混和材）、市販品Ｃ（フォーステライト質系混和材）に対してもコテ塗り作業性が優位であり、市販品Ａ（石綿系混和材）と比較しても「ダレにくさ」の面で優位であった。
次に、モルタルのレオロジー特性に関して、実施例の左官モルタル用混和材は、プレーンモルタルおよび比較例の混和材に対して、塑性粘度が低く、降伏値が高くなる傾向にあった。塑性粘度が低いということは、コテ塗りの際に低い力で流動しやすいことを意味し、「コテ伸び」「コテ滑り」の良さに繋がっている。また、降伏値が高いということは、「ダレにくい」ということを示している。このように、レオロジー特性の面からも、作業性の良さが裏付けられるものと考えられる。
The admixture for plastering mortar of the example improved the ironing workability for plain mortar, and greatly improved the “iron elongation”, “iron slipping”, “iron separation”, “sagging” and “finishing aesthetics”. Also, the ironing workability is superior to the commercial product B (serpentine-based admixture) and the commercial product C (forsterite-based admixture), compared with the commercial product A (asbestos-based admixture). Was also dominant in terms of “sagging”.
Next, regarding the rheological properties of the mortar, the plastering mortar admixture of the example had a lower plastic viscosity and a higher yield value than the plain mortar and the admixture of the comparative example. The low plastic viscosity means that it is easy to flow with a low force during the application of the iron, which leads to good “elongation” and “iron sliding”. In addition, a high yield value indicates that “sag is difficult”. Thus, it is considered that good workability is supported also from the viewpoint of rheological characteristics.
さらに、実施例の左官モルタル用混和材は、プレーンモルタルと比較して付着強度が向上し、市販品に対しても遜色ない付着強度であった。
以上の試験結果から、本発明の左官モルタル用混和材は、石綿等の有害な成分を含有せず、かつモルタルのコテ塗り時において作業性、ダレ防止、仕上がり等の面で、従来の左官モルタル用混和材と比較して優位な性能を発揮できるものである。
Furthermore, the admixture for plastering mortars of the examples had improved adhesion strength compared to plain mortar, and had an adhesion strength comparable to that of commercially available products.
From the above test results, the admixture for plastering mortar of the present invention does not contain harmful components such as asbestos, and in terms of workability, sag prevention, finish, etc. when applying mortar iron, Compared with admixtures for use, it can exhibit superior performance.
以下、本発明の実施の形態について説明する。
本発明の左官モルタル用混和材に使用するクレーは、カオリナイト、ハロイサイト、パイロフィライト、タルク、クロライト、モンモリロナイト、ムスコバイト、バーミキュライトからなる群から選ばれた１種または２種以上の粘土系鉱物を含有する。これらクレーは、上記の粘土鉱物の含有量の高いものや他の鉱物が大量に共存して純度的に低いものもあるが、前記の粘度鉱物が少なくとも２０％以上含有することが必要である。
本発明で使用できる上記クレーは、平均粒子径が０．３〜３０μｍ内にあるものであり、好ましくは０．８〜１５μｍである。クレーの平均粒子径が３０μｍを超えると、左官モルタル用混和材として使用した際、コテ塗り時の作業性向上効果が極めて低くなる。また、クレーの平均粒子径が０．３μｍ未満であると、左官モルタル用混和材として使用した際、一定の流動性を得るために必要な混練水の量が多くなるため、モルタル硬化体の強度特性が低くなるという問題が生ずる。
Embodiments of the present invention will be described below.

Contains minerals. Some of these clays have a high content of the above-mentioned clay minerals, and other clay minerals coexist in large quantities and have a low purity. However, the clay mineral needs to contain at least 20% or more.
The clay that can be used in the present invention has an average particle diameter of 0.3 to 30 μm, preferably 0.8 to 15 μm. When the average particle size of the clay exceeds 30 μm, the workability improvement effect during the application of the iron becomes extremely low when used as an admixture for plastering mortar. Moreover, when the average particle size of the clay is less than 0.3 μm, the amount of kneading water required to obtain a certain fluidity increases when used as an admixture for plastering mortar. There arises a problem that the characteristics are lowered.
