Abstract
Description
この発明は、壁面用塗材に関するものであり、特にブロック壁面のような凹凸部を有する壁面に適した鏝塗り可能な壁面用塗材に関するものである。 The present invention relates to a wall surface coating material, and more particularly, to a wall surface coating material suitable for a wall surface having an uneven portion such as a block wall surface.
従来、合成樹脂エマルションをバインダーとした壁面用塗材が知られているが、このような壁面用塗材をコンクリートブロックの壁面あるいは目地模様等の凹凸部を有する壁面に直接塗布した場合、乾燥後の塗膜の痩せによりブロックの段違い、目地部の不陸のような壁面の凹凸を解消することができず、平坦な仕上げ面が得られないものであった。
そのため凹凸部を有する壁面の一般的な化粧方法としては、セメントモルタルによる下地調整を施し、その上に表面化粧材を塗るという方法が一般的であった。
しかしながらセメントモルタルによる下地調整作業は、壁面の僅かな不陸に対してもセメントモルタルを3mm以上の厚みで塗布することを余儀なくされるので、塗布作業に多大な労力を要するものであった。また、養生・硬化に3〜7日の工期を要するものであり、施工に長期間を要するものであった。
Conventionally, wall surface coating materials using a synthetic resin emulsion as a binder are known, but when such wall surface coating materials are applied directly to a wall surface of a concrete block or a wall surface having uneven portions such as joint patterns, it is dried. Due to the thinning of the coating film, the unevenness of the wall surface, such as unevenness of the blocks and unevenness of the joints, could not be eliminated, and a flat finished surface could not be obtained.
For this reason, as a general makeup method for a wall surface having an uneven portion, a method of applying a base preparation with cement mortar and applying a surface decorative material thereon has been common.
However, in the groundwork adjustment work using cement mortar, it is necessary to apply the cement mortar with a thickness of 3 mm or more even for a slight unevenness of the wall surface, and therefore, the application work requires a great deal of labor. In addition, it takes 3 to 7 days for curing and curing, and it takes a long time for construction.
そこで特許文献1には、凹凸部を有する壁面の仕上方法として、無機質充填材、炭素繊維、合成樹脂エマルションバインダーからなる塗材を、凹凸部を有する壁面、ブロック塀の場合は目地部分に塗布し、乾燥後に上塗仕上材を塗布するという方法が示されている。
さらに特許文献2には、炭素繊維と合成繊維を混合した繊維材料を添加した壁面仕上げ塗材が示されている。
特許文献1および特許文献2によれば、炭素繊維が無機質充填材と共に不織布のような構造を形成し、その集合による補強効果によって、塗り面の引っ張り強さ等の機械的物性が向上し、塗膜の乾燥による痩せ並びにクラックの発生が抑制できる。
Therefore, in Patent Document 1, as a method for finishing a wall surface having an uneven portion, a coating material composed of an inorganic filler, carbon fiber, and a synthetic resin emulsion binder is applied to a wall surface having an uneven portion, or a joint portion in the case of a block wall. A method of applying a top coating material after drying is shown.
Further, Patent Document 2 discloses a wall surface finish coating material to which a fiber material in which carbon fibers and synthetic fibers are mixed is added.
According to Patent Document 1 and Patent Document 2, the carbon fiber forms a structure like a nonwoven fabric together with the inorganic filler, and the mechanical properties such as the tensile strength of the coated surface are improved by the reinforcing effect by the assembly, and the coating is performed. It is possible to suppress the occurrence of thinning and cracks due to drying of the film.
しかしながら、特許文献1、2に示される仕上方法であっても、凹部分やブロックの目地部分に充填した塗材には乾燥後に痩せが生じるため、上塗り仕上材の厚みが1mm以下の塗り厚であれば、その部分に痩せが生じ、凹凸を解消することができない。
従って、上塗り仕上げ材は、粒径2〜3mmの骨材を使用して3mm程度の塗り厚とするか、あるいは複数回の重ね塗りを行わなければならないものであった。
However, even in the finishing methods shown in Patent Documents 1 and 2, since the coating material filled in the concave portion and the joint portion of the block is thin after drying, the thickness of the top coating material is 1 mm or less. If there is, the skin becomes thin and the unevenness cannot be eliminated.
Therefore, the top coat finish material has to have a coating thickness of about 3 mm by using an aggregate having a particle size of 2 to 3 mm, or a plurality of times of repeated coating.
粒径2〜3mmの大きい骨材を使用した場合、塗膜表面がザラザラとした仕上りとなり、塗り壁独特の滑らかな塗膜を形成することが出来ず、鏝塗りする際に大きい骨材が転がり模様付けの妨げとなっていた。またこのような大きな骨材は、重量が大きいため、作業性の悪化を伴うものであった。
小さな骨材を使用して複数の重ね塗りを行う場合、多彩な模様付けが可能で、塗り壁独特の風合いを出すことが可能だが、平坦な塗膜を得るために何回もの重ね塗りをしなければならず、工期が長期間におよぶという問題があった。
When a large aggregate with a particle size of 2 to 3 mm is used, the surface of the paint film is rough, and a smooth paint film unique to the painted wall cannot be formed. It was a hindrance to patterning. Moreover, such a large aggregate is accompanied by a deterioration in workability due to its large weight.
When multiple coatings are performed using small aggregates, it is possible to create a variety of patterns and create a unique texture of the coating wall, but it is necessary to apply several times to obtain a flat coating film. There was a problem that the construction period was long.
乾燥後の塗膜に痩せが生じる原因の一つとして、塗膜の乾燥スピードが遅いということも重要な因子の一つである。即ち、塗膜の乾燥スピードが遅いということは、多量の水分を含有していることであり、塗布後の塗膜からこれら水分が蒸発することによって、塗膜の痩せが生じる。
従って、塗膜の痩せを抑えるためには、添加する水分と蒸発する水分を低減することが有効である。しかしながら、単に壁材組成物への添加水量を減らしただけでは、鏝等により塗布する際の作業性の悪化を招くものである。
As one of the causes of the thinness of the coating film after drying, one of the important factors is that the drying speed of the coating film is slow. That is, the slow drying speed of the coating film means that a large amount of moisture is contained, and the coating film becomes thin due to evaporation of the moisture from the coating film after coating.
Therefore, in order to suppress the thinning of the coating film, it is effective to reduce the added water and the evaporated water. However, simply reducing the amount of water added to the wall material composition leads to deterioration in workability when applied with wrinkles or the like.
本発明の目的は、凹凸部を有する壁面、例えば目地部を有するコンクリートブロックの壁面の平滑処理並びに表面仕上げを行うことができ、作業性に優れ、塗膜表面が滑らかで塗り壁独特の風合いを出すことができ、耐クラック性にも優れた壁面用塗材を提供するものである。 An object of the present invention is to perform smoothing treatment and surface finishing of a wall surface having an uneven portion, for example, a wall surface of a concrete block having a joint portion, which is excellent in workability, has a smooth coating surface, and has a unique texture on the coating wall. The present invention provides a wall surface coating material that can be put out and has excellent crack resistance.
本発明者等は、このような事情に鑑み種々の試験を繰り返した結果、粒径が1mm以下の無機質骨材100重量部に対し、線径5〜50μm、長さ0.5〜30mmの繊維を0.2〜1.0重量部、鉄鋼スラグを1〜10重量部、樹脂固形分が40〜50%の合成樹脂エマルションバインダーを15〜20重量部及び水を15〜25重量部の割合で添加した壁面用塗材とすることにより、所期の目的を達成することを認め本発明を完遂するに至った。 As a result of repeating various tests in view of such circumstances, the present inventors have found that a fiber having a diameter of 5 to 50 μm and a length of 0.5 to 30 mm with respect to 100 parts by weight of an inorganic aggregate having a particle size of 1 mm or less. 0.2 to 1.0 parts by weight, steel slag 1 to 10 parts by weight, resin solid content 40 to 50% of synthetic resin emulsion binder 15 to 20 parts by weight and water 15 to 25 parts by weight Recognizing that the intended purpose was achieved by using the added coating material for wall surface, the present invention was completed.
すなわち本発明の壁面用塗材は、無機質骨材、繊維、鉄鋼スラグ、合成樹脂エマルションバインダー及び水を所定の割合で配合したものなので、乾燥過程において鉄鋼スラグと塗膜内部の水分との水和反応により塗膜内部の水分量が減少すると共に塗膜の乾燥が促進され、塗膜の痩せを抑制することができる。また施工後の塗膜は、繊維が絡み合って均一に分散して不織布のような構造を形成し、それらの繊維同士の補強硬化によって塗膜の引っ張り強度、曲げ強さ、ひび割れ抵抗性、靭性、耐ムービング性などの物性が向上し、塗膜の痩せやクラックを抑制する。 That is, the wall surface coating material of the present invention is a mixture of inorganic aggregate, fiber, steel slag, synthetic resin emulsion binder and water in a predetermined ratio, so that the hydration of steel slag and moisture inside the coating film during the drying process. The amount of water inside the coating film is reduced by the reaction, and drying of the coating film is promoted, so that the thinning of the coating film can be suppressed. In addition, the coating film after construction forms a structure like a non-woven fabric with fibers entangled and uniformly dispersed, and the tensile strength, bending strength, crack resistance, toughness of the coating film by reinforcing and curing those fibers. Improves physical properties such as moving resistance and suppresses thinning and cracking of the coating film.
本発明の壁面用塗材によれば、塗膜の痩せを抑えることができるので、コンクリートブロックあるいは目地模様等の凹凸部を有する壁面に塗布しても、塗膜により下地表面の凹凸部を消失することができ、塗膜の乾燥が早いので、施工期間を短縮することができる。また、無機質骨材は粒径が1mm以下のものを使用しているので、塗膜表面が滑らかで塗り壁独特の風合いのある塗布面を得ることができる。 According to the coating material for wall surface of the present invention, since the thinning of the coating film can be suppressed, even if it is applied to a wall surface having an uneven part such as a concrete block or joint pattern, the uneven part of the underlying surface is lost by the coating film. Since the coating film dries quickly, the construction period can be shortened. Further, since the inorganic aggregate having a particle size of 1 mm or less is used, it is possible to obtain a coated surface having a smooth coating film surface and a unique texture of the painted wall.
無機質骨材は、粒径が1mm以下のものが好ましく使用される。1mmを超えた骨材を配合すると、塗膜表面がザラザラとした仕上りとなり、塗り壁独特の滑らかな塗膜を形成することが出来ず、多彩な模様付けを行うことが出来ない。
さらに、全無機質骨材中の5〜40重量%の骨材の粒径を0.1mm以下とすることにより、配合する繊維の分散性を改善すると共に、塗膜の痩せを抑えつつ表面の滑らかな塗膜を得ることができる。
As the inorganic aggregate, those having a particle size of 1 mm or less are preferably used. If an aggregate exceeding 1 mm is blended, the surface of the coating film will be rough, a smooth coating film unique to the coating wall cannot be formed, and various patterns cannot be formed.
Furthermore, by making the particle size of the aggregate of 5 to 40% by weight in the total inorganic aggregate 0.1 mm or less, the dispersibility of the fibers to be blended is improved and the surface is smooth while suppressing the thinning of the coating film. Can be obtained.
本発明の実施に適する代表的な無機質骨材としては、硅砂、寒水石などが挙げらるが、特に吸水率が30%以下の吸水量の少ない骨材であれば、種々の骨材を使用することができる。これら無機質骨材は各々単独で用いても、2種以上を混合して用いても構わない。
なお、骨材の吸水率は、JISA1110に準拠して求めた。具体的には、湿潤状態の骨材の表面水を完全に拭い去って表面乾燥飽水状態の重量をBとし、その骨材を100〜110℃の温度で定重量となるまで乾燥した絶対乾燥状態の重量をAとし、吸水率は(B−A)÷A×100の式により求めた値を吸水率とした。
硅石粉、珪藻土、クレー、タルクなど吸水率の高い無機質骨材の使用は、骨材が吸収する水が多くなるので、塗材に調製する際の添加水量が多くなり、乾燥後における塗膜の体積減少が著しく、目地部の痩せ、もしくは凹凸の原因となるので使用すべきではない。
Typical inorganic aggregates suitable for the practice of the present invention include dredged sand, cryolite, etc., but various aggregates are used as long as the water absorption is 30% or less and the aggregate has a low water absorption. can do. These inorganic aggregates may be used alone or in combination of two or more.
In addition, the water absorption rate of the aggregate was calculated | required based on JISA1110. Specifically, the surface water of the aggregate in a wet state is completely wiped off, and the weight of the surface dry saturated state is set to B, and the aggregate is dried at a temperature of 100 to 110 ° C. until a constant weight is obtained. The weight of the state was A, and the water absorption was a value obtained by the formula of (B−A) ÷ A × 100.
The use of inorganic aggregates with high water absorption, such as aragonite powder, diatomaceous earth, clay, talc, etc., increases the amount of water absorbed by the aggregate. It should not be used because the volume is significantly reduced and the joints become thin or cause unevenness.
本発明の実施において使用される繊維として、炭素繊維、合成繊維等が使用される。これら繊維は、無機質骨材100重量部に対して0.3〜1.0重量部の割合で添加される。繊維の配合量が、1.0重量部を超えると、繊維が鏝にまとわりついて作業性が悪化する。0.3重量部を下回ると、塗膜のクラック発生を抑えることができない。炭素繊維、合成繊維は夫々単独で使用しても構わないが、炭素繊維と合成繊維を併用して配合することにより、炭素繊維の分散性を改善すると共に、黒色の炭素繊維による美観の低下を防止することができる。 Carbon fibers, synthetic fibers, and the like are used as fibers used in the practice of the present invention. These fibers are added at a ratio of 0.3 to 1.0 part by weight with respect to 100 parts by weight of the inorganic aggregate. When the blending amount of the fiber exceeds 1.0 part by weight, the workability is deteriorated due to the fibers clinging to the bag. If it is less than 0.3 parts by weight, the occurrence of cracks in the coating film cannot be suppressed. Carbon fiber and synthetic fiber may be used alone, but by combining carbon fiber and synthetic fiber in combination, the dispersibility of carbon fiber is improved and the appearance of black carbon fiber is reduced. Can be prevented.
炭素繊維としては、ポリアクリルニトリル系あるいはピッチ系のいずれも使用することができ、その大きさは線径5〜50μm、繊維長0.5〜30mmの範囲にあるものが適している。炭素繊維の太さが5μmより小さいもの、あるいは繊維長が0.5mmより短いもの用いた場合には、乾燥した塗膜の抗張力が乏しく、塗膜のクラック発生を十分に抑制することができない。このように所定サイズの炭素繊維を所定の割合で配合することにより、塗り付け時に塗材の表面に炭素繊維が存在し、鏝塗り及び鏝すべりが改善され、優れた塗布性能が得られる。
炭素繊維は、カール状の炭素繊維を使用することにより、繊維同士が立体的に絡み合い、塗膜の痩せを少なくし、塗膜強度をアップさせることができる。
As the carbon fiber, either polyacrylonitrile-based or pitch-based can be used, and those having a wire diameter of 5 to 50 μm and a fiber length of 0.5 to 30 mm are suitable. When a carbon fiber having a thickness of less than 5 μm or a fiber length of less than 0.5 mm is used, the tensile strength of the dried coating film is poor, and cracking of the coating film cannot be sufficiently suppressed. By blending carbon fibers of a predetermined size in a predetermined ratio in this way, carbon fibers are present on the surface of the coating material at the time of application, so that glazing and glazing are improved and excellent coating performance is obtained.
By using curled carbon fibers, the carbon fibers can be three-dimensionally entangled with each other, reducing the thinness of the coating film and increasing the coating film strength.
合成繊維としては、ポリプロピレン繊維、ナイロン繊維、アクリル繊維、ポリエステル繊維及びレーヨン繊維等が挙げられ、これらの繊維は単独あるいは2種類以上併用しても構わないが、塗布後における塗膜の物性および強度が良好となる点において、ポリエステル繊維、エステル繊維が好適である。 Synthetic fibers include polypropylene fibers, nylon fibers, acrylic fibers, polyester fibers, rayon fibers, etc. These fibers may be used alone or in combination of two or more, but the physical properties and strength of the coating film after coating Polyester fiber and ester fiber are preferred in that the is good.
合成繊維の大きさは、線径5〜50μm、繊維長0.5〜30mmの範囲が好ましく、繊維の太さが5μmより小さいもの、繊維長が0.5mmより小さいものを用いた場合は、乾燥した塗膜の抗張力が乏しく、塗膜のクラック発生を十分に抑制することができない。一方、繊維の径が50μmを超えるものは、均一に分散混合させることが難しく生産性が著しく阻害され、繊維長が30mmを超える場合は、無機質骨材との配合性が悪くなり、且つ壁面に塗布する際に合成繊維が鏝にまとわりついて、鏝伸び、鏝離れなどの作業性が悪化するので、いずれも好ましくない。 The size of the synthetic fiber is preferably a wire diameter of 5 to 50 μm and a fiber length of 0.5 to 30 mm. When the fiber thickness is smaller than 5 μm, or the fiber length is smaller than 0.5 mm, The tensile strength of the dried coating film is poor, and the occurrence of cracks in the coating film cannot be sufficiently suppressed. On the other hand, when the fiber diameter exceeds 50 μm, it is difficult to uniformly disperse and mix, and the productivity is remarkably impaired. When the fiber length exceeds 30 mm, the compounding with the inorganic aggregate is deteriorated, and the wall surface When applying, synthetic fibers cling to the cocoon and workability such as cocoon stretching and separation of the cocoon deteriorates.
本発明の実施に当たって、炭素繊維と合成繊維を併用する場合の重量配合比は1:4〜4:1の範囲とすべきであり、この範囲を超えて炭素繊維の配合量を多くすると、黒色の斑模様が表出されて塗膜表面の美観が低下し、この範囲を下回った場合には、塗膜の引っ張り強度、曲げ強さ、ひび割れ抵抗性、靭性、耐ムービング性などの物性向上、並びに塗膜の痩せ、クラック発生防止等が期待できない。 In the practice of the present invention, the weight blending ratio when carbon fibers and synthetic fibers are used in combination should be in the range of 1: 4 to 4: 1. The appearance of the surface of the paint film appears and the aesthetics of the paint film surface deteriorates, and if it falls below this range, physical properties such as the tensile strength, bending strength, crack resistance, toughness, and moving resistance of the paint film are improved. In addition, thinning of the coating film, prevention of cracking, etc. cannot be expected.
本発明の実施において使用される鉄鋼スラグとしては、高炉スラグが好ましく用いられる。高炉スラグは生成方法の違いから徐冷スラグと水砕スラグの2種類に分類されるが、塗り壁や塗料に用いる場合は、粒度の細かい水砕スラグが適しており、粒径が0.1mm以下のものが好ましく使用される。
従来の壁材を凹凸面に塗布した場合、経時変化に伴い表面水が蒸発し、塗面全体的に痩せが生じ、完全乾燥した時点で凹凸がそのまま塗膜表面に現れることがある。
鉄鋼スラグには水和反応による潜在硬化特性があるため、塗布後に塗膜内部の水分と鉄鋼スラグの水和反応が進み、それによって塗膜内部の硬化が促進され、さらに塗膜の乾燥時間が短縮できるので、塗膜の痩せを抑制することができると共に、工期を短縮するメリットもある。
As the steel slag used in the practice of the present invention, blast furnace slag is preferably used. Blast furnace slag is classified into two types, slow-cooled slag and granulated slag, depending on the production method. When used for painted walls and paints, fine granulated granulated slag is suitable, and the particle size is 0.1 mm. The following are preferably used.
When a conventional wall material is applied to the uneven surface, the surface water evaporates with time, and the entire coated surface becomes thin, and the unevenness may appear as it is on the surface of the coating film when completely dried.
Since iron and steel slag has latent curing properties due to hydration reaction, the hydration reaction of the water inside the coating film and the steel slag proceeds after application, which accelerates the hardening of the coating film inside, and further the drying time of the coating film. Since it can be shortened, the thinning of the coating film can be suppressed, and there is an advantage of shortening the construction period.
鉄鋼スラグの配合量は無機質充填材100重量部に対して、1〜10重量部が好ましく、より好ましくは3〜5重量部の範囲である。1重量部より少ないと、水和反応による塗膜乾燥促進が期待できず、10重量部を超えると、塗材の粘度が極端に上昇し鏝滑り等の作業性が低下する。 As for the compounding quantity of steel slag, 1-10 weight part is preferable with respect to 100 weight part of inorganic fillers, More preferably, it is the range of 3-5 weight part. When the amount is less than 1 part by weight, acceleration of drying of the coating film due to a hydration reaction cannot be expected, and when the amount exceeds 10 parts by weight, the viscosity of the coating material is extremely increased and workability such as wrinkling is reduced.
本発明の実施において使用される代表的なバインダーとしては、酢酸ビニル樹脂系(エチレン−酢酸ビニル共重合体、酢ビ−塩化ビニル共重合体、酢酸ビニル−ベオバ共重合体など)、アクリル樹脂系(アクリル−スチレン共重合体、アクリル−エチレン−酢酸ビニル共重合体など)、ベオバ樹脂系などのエマルションが用いられる。
合成樹脂エマルションバインダーは樹脂固形分を40〜50%の範囲とし、無機質骨材100重量部に対し、15〜20重量部の割合で添加される。合成樹脂エマルションバインダーの添加量が、少ないと塗面に所定の強度を付与することができず、逆に添加量が多くなると鏝塗作業における材料の鏝離れが悪くなり作業性が悪化する。
Typical binders used in the practice of the present invention include vinyl acetate resin systems (ethylene-vinyl acetate copolymer, vinyl acetate-vinyl chloride copolymer, vinyl acetate-veova copolymer, etc.), acrylic resin systems (Acrylic-styrene copolymer, acrylic-ethylene-vinyl acetate copolymer, etc.), emulsions such as Veova resin are used.
The synthetic resin emulsion binder has a resin solid content in the range of 40 to 50%, and is added at a rate of 15 to 20 parts by weight with respect to 100 parts by weight of the inorganic aggregate. If the addition amount of the synthetic resin emulsion binder is small, a predetermined strength cannot be imparted to the coating surface. Conversely, if the addition amount is large, the separation of the material in the glazing operation becomes worse and the workability deteriorates.
本発明の壁面用塗材を調製する際、無機質骨材100重量部に対し、水が15〜20重量部の割合で添加される。水の添加量は塗布作業性に影響を与えない範囲で、極力抑えるべきであり、この範囲を超えると、塗膜の乾燥に長時間を要し、塗膜の痩せを抑えることができない。 When preparing the coating material for wall surfaces of this invention, water is added in the ratio of 15-20 weight part with respect to 100 weight part of inorganic aggregates. The amount of water to be added should be suppressed as much as possible within a range that does not affect the coating workability. If the amount exceeds this range, it takes a long time to dry the coating film, and the thinning of the coating film cannot be suppressed.
本発明壁面用塗材を用いた化粧方法は、目地部を有するブロック壁面又は凹凸部を有する壁面に、本発明塗材を塗布乾燥して、下地の平滑処理を行った後、表面仕上げを行うものであるが、一般的に使用されている下地調整材を使用して平滑処理を行った後、本発明塗材を用いて表面仕上げを行うこともできる。 In the makeup method using the coating material for wall surface of the present invention, the coating material of the present invention is applied and dried on a block wall surface having joints or a wall surface having uneven portions, and the surface is smoothed, and then surface finishing is performed. However, it is also possible to perform surface finishing using the coating material of the present invention after performing a smoothing process using a commonly used base material adjusting material.
本発明の壁面用塗材は、無機質骨材、繊維及び鉄鋼スラグをリボンブレンダーあるいは高速流動式攪拌機を用いてドライ混合し、使用する際にこれに合成樹脂エマルションバインダーと水を加えて均一に混練して調製される。なお、必要に応じて色出しのために使用する顔料などを計量して添加する。 The coating material for wall surface of the present invention is dry-mixed with inorganic aggregate, fiber and steel slag using a ribbon blender or a high-speed flow type stirrer, and when used, a synthetic resin emulsion binder and water are added and kneaded uniformly. Prepared. If necessary, pigments used for color development are weighed and added.
本発明の実施に当り、壁面用塗材を鏝塗りするのに適した粘度とするために水溶性糊料が添加される、水溶性糊料としてはカルボキシメチルセルロース、メチルセルロース、ヒドロキシエチルセルロースなどが挙げられ、これらは骨材100重量部に対し、0.2〜0.5重量部の範囲で添加される。水溶性糊料の配合量が0.5重量部を上回ると、塗材の粘度が極端に上昇し、0.2重量部を下回ると、塗布するのに必要な粘度が得られなくなる。水溶性糊料は、無機質骨材、繊維及び鉄鋼スラグと共にリボンブレンダーあるいは高速流動式攪拌機を用いてドライ混合される。 In practicing the present invention, a water-soluble paste is added in order to obtain a viscosity suitable for applying a wall coating material to the wall, and examples of the water-soluble paste include carboxymethylcellulose, methylcellulose, and hydroxyethylcellulose. These are added in the range of 0.2 to 0.5 parts by weight with respect to 100 parts by weight of the aggregate. When the blending amount of the water-soluble paste exceeds 0.5 parts by weight, the viscosity of the coating material is extremely increased, and when it is less than 0.2 parts by weight, the viscosity necessary for coating cannot be obtained. The water-soluble paste is dry-mixed together with the inorganic aggregate, fiber and steel slag using a ribbon blender or a high-speed fluidized stirrer.
本発明の実施に当り、必要に応じて顔料、防錆剤、防腐剤、消泡剤、保水剤、アク・シミ止め剤、鏝滑剤等を本発明の効果に影響を与えない範囲で、適宜添加することができる。 In carrying out the present invention, pigments, rust preventives, antiseptics, antifoaming agents, water retention agents, anti-smudge agents, lubricants, etc., as necessary, are appropriately selected within a range that does not affect the effects of the present invention. Can be added.

[Comparative Example 2]
As an inorganic filler, 7500 g of cryolite with a particle size of 0.3 to 1.0 mm, 900 g of cinnabar sand with a particle size of 0.3 mm or less, 25 g of methylcellulose, and 400 g of granulated slag with a particle size of 0.1 mm or less are put into a ribbon blender.

As a result, a thinness of 1 mm at the maximum occurred in the joint portion, and fine cracks were locally generated.
実施例1と比較例1で調製した塗材をそれぞれ塗り厚2mmで大きさ300×300mmの石膏スレートフレキシブル板に塗布し試験片を作成した。試験片を気温20℃、湿度55%の条件下で24時間乾燥した後、23℃の水中に24時間浸漬した。その結果、実施例1の試験片は塗膜に浮きや剥がれが生じなかったが、比較例1の試験片は、塗膜に浮きや剥がれが生じた。
このような現象は、実施例1の鉄鋼スラグを配合した塗膜は完全に乾燥し硬化していたが、比較例1の鉄鋼スラグを入れなかった塗膜は、内部が充分に乾燥しておらず、塗膜が未硬化であったことに起因するものと思われる。
The coating materials prepared in Example 1 and Comparative Example 1 were each applied to a plaster slate flexible plate having a coating thickness of 2 mm and a size of 300 × 300 mm to prepare a test piece. The test piece was dried for 24 hours under conditions of an air temperature of 20 ° C. and a humidity of 55%, and then immersed in water at 23 ° C. for 24 hours. As a result, the test piece of Example 1 was not lifted or peeled off from the coating film, but the test piece of Comparative Example 1 was lifted or peeled off from the coating film.
In such a phenomenon, the coating film containing the steel slag of Example 1 was completely dried and cured, but the coating film without the steel slag of Comparative Example 1 was sufficiently dried inside. It seems that this is because the coating film was uncured.
