Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building finish coating material and a building finish panel using volcanic ash white sand (hereinafter referred to as "shirasu"), and to a method for producing these.

[0002]

2. Description of the Related Art In recent years, various studies have been made in the field of construction in order to utilize shirasu, which has abundant reserves. In most cases, there was no building finish coating material or building finish panel which commercialized Shirasu in its original form without processing.

[0003] That is, Shirasu is a common name of white sandy sediment, and is a general term for white rough eruptive volcanic products widely distributed in southern Kyushu and secondary sediments derived therefrom. This shirasu causes a crystal differentiation action by cooling of the high-temperature magma, and the main components SiO2, Al2O3, Fe2O3,
FeO, MgO, CaO, Na2O, K2O, etc. are gathered together and crystallized as minerals and explosively erupt shortly. They are formed by about 30% of crystalline minerals and about 70% of amorphous volcanic glass. Made up of The amorphous volcanic glass emits volatile components in the magma rapidly to form a porous pumice, with 65 to 73% SiO2 and 12 to 1 Al2 O3.
6%, 2-4% of CaO, 3-4% of Na2O, 2-4% of K2O and 1-3% of iron. Crystalline minerals are most often plagioclase, and also contain some perovskite, quartz, ordinary pyroxene, and magnetite.

[0004] In addition, some types of shirasu float on water when shirasu is rapidly heated. This is called "shirasu balloon" (1970, Kyushu Industrial Technology Test and Research). It is known to form The size of this shirasu balloon is about 30 to 600 μm, and it has features such as low cost, nonflammability, low bulk density, high melting point, low thermal conductivity, low dielectric constant, harmlessness, and no generation of toxic gas. 600-3000 μm
Are also produced. The main uses of shirasu balloons are industrial paints and the like that are lightweight and can be thickly applied. In recent years, the use of these materials for architectural purposes such as ceiling materials, which are lightweight and do not require relatively high strength, has become full-scale. In addition, the development of polymer composite materials using finely ground shirasu is also progressing.

Conventionally, earth wall and plaster are used as plaster finish wall materials and painted wall materials as building finish wall materials. This clay wall puts sand in clay to prevent cracks,
A mixture of Tokyo straw for middle walls, rotten black straw, root straw, manila hemp, carbon fiber, etc. for rough walls, and plaster made from slaked lime and kneaded with glue, susa, straw, paper, etc. It is. In addition, diatomaceous earth, which is so-called algae sedimentary soil, which is phytoplankton, is used as a wall base material, a refractory brick, and a wall finishing material. In addition, as the self-hardening material for the earth wall, there are lime, dolomite plaster, cement and the like, in addition to clay, and a method is used in which these materials are mixed with clay to strengthen the property of hardening.

[0006]

However, according to the above-mentioned prior art, most shirasu are secondarily processed, and shirasu, which is abundant resource, is directly commercialized without processing in its original form. Things did not exist. This is due to the extremely high fluidity of shirasu in water.

For example, the data shown in FIG. 3 shows a state in which the ground surface of Shirasu is eroded by rainwater or the like, and the ground surface is rubbed off, and numerous deep valleys appear. This document confirms the fact that Shirasu is highly mobile to water.

[0008] Research on the effective use of such shirasu, which has a high fluidity with respect to water, has been conducted for many years in Kagoshima Prefecture, which is the place of origin of shirasu. The fact is that it has not been reached.

[0009] One of the biggest factors in which a coating material or the like using shirasu is not commercialized is that cracks are generated on the surface of the shirasu when the shirasu is applied as a wall or the like.

Another is a so-called water flow phenomenon of shirasu. This is a phenomenon in which, when a predetermined amount of water is added to kneaded and kneaded and applied to a base board or the like, not a drying from the surface but a large amount of contained water flows down in the drying process of the shirasu.

Due to such cracking phenomenon and water flow phenomenon of the shirasu, the original characteristics of the shirasu cannot be utilized to effectively use it as a building finish coating material or a building finish panel.

[0012] On the other hand, the use of conventional chemical substances and organic materials has hardly taken measures against chemical substance hypersensitivity or sick house, and has hardly been used as a substitute building material for depleted sand. It was the actual situation.

[0013] In addition, conventionally, measures against adverse effects on the human body due to alkalinity at the time of construction, pillars in the room,
Measures to prevent discoloration of wood or spots at the contact points of the surrounding edge, picture frame, baseboard, etc., to prevent cracks from being generated at the joints of the underlying board, and to strengthen the adhesion of the board surface as a base treatment Special measures have been required for the construction, for example, by applying the agent in advance to prevent peeling.

Therefore, the present invention has been made in view of the above-mentioned problems which have existed in the past, and the present invention utilizes volcanic ash shirasu, which is an abundant resource, in its original unprocessed form to effectively utilize shirasu's original features. The soft and rough feeling of the skin can be apparently raised, and it can also be used as a preventive measure against chemical sensitivities and a sick house, and can be used as an alternative building material for depleted sand. , Energy saving, resource saving, non-pollution, detoxification, low price, inorganic properties, extensibility, coloring, fire resistance, fire protection, sound insulation, humidity control, antibacterial, heat storage insulation, An object of the present invention is to provide a building finish coating material and a building finish panel having deodorant properties, air permeability, and the like, and a method for producing these.

Further, the present invention solves the so-called cracking phenomenon and water flow phenomenon of shirasu, which are mainly caused by separation of water and shirasu, by mixing a highly water-retaining clay material or the like,
By realizing the commercialization of Shirasu as a coating material, etc., it has been highly evaluated by the Kyushu Industrial Technology Laboratory, the Kagoshima Industrial Technology Center (especially the material development department in the center), the Miyazaki Industrial Technology Center, etc. .

[0016] In the market, Shirasu, which had been traded at around 3,000 yen for 10 tons, will be traded at around 10,000 yen for 10 kg by utilizing the present invention.
An extremely high market revitalization effect is occurring.

It does not require any costs and costs, and does not cause pollution. In addition, because it is inorganic, it is resistant to ultraviolet rays and heat, and is also resistant to natural disasters such as fires, floods, typhoons, etc. In addition, Shirasu is porous, pumice-like and has breathability, condensing the house structure itself Etc., to remove moisture,
It exhibits antibacterial properties to control mold and the like.

The main component of the dried shirasu is silicic acid / silicon dioxide (silica) having a composition ratio of 65 to 73%.
It is. Silicic acids with negative charge are cationic metals / alumina, iron, magnesium, titanium, manganese,
Combined with positively charged cations such as calcium, sodium, potassium, etc., and hydrogen, they form neutral crystals and form so-called shirasu. These mixtures are formed under high temperature by magma. Therefore, it has special physical properties. In particular, shirasu balloons produced at high temperatures contain gas and have the properties of excellent heat retention and heat insulation properties, and this trait makes use of shirasu as wall materials, building materials, and building auxiliary materials. Will be an important factor.

Further, silicic acid has a very high hygroscopicity, as is known as a raw material of a dehumidifying agent such as silica gel, and has a characteristic of strong water retention as potassium silicate when combined with potassium. It can also be used as a water retention material to protect the roots of local plants.

Alumina, which accounts for 12 to 16% of the composition ratio of shirasu, is a chemical species fired at a high temperature, and has the characteristic that the porous structure having a large surface area has a very large water and gas adsorption power. In combination with the hygroscopic property of silicic acid and the hygroscopic and water-retentive properties of potassium silicate, it has an extremely high effect on dehumidification and humidity adjustment.

In addition, since titanium bound to silicic acid having a negative charge has a positive charge and is included as titanium oxide, if it is involved in the shirasu material in any way,
It reacts with hydrogen and humidity / moisture in air to generate active oxygen species, and exhibits various cleaning effects such as decomposition of organic substances dissolved in air and water and deodorizing effects accompanying decomposition of organic substances.

In addition, hydrogen in the shirasu component combines with oxygen to form a hydroxyl group / hydroxyl radical (.OH), and a superoxide anion is formed from water molecules and oxygen which come into contact in the process of exchange of high potential. radical(·
02 ^-) active oxygen species / free radicals, such as are generated. Since reactive oxygen species / free radicals have strong bactericidal and organic substance decomposing abilities, shirasu materials containing such a reaction system are highly effective in purifying, sterilizing and deodorizing air passing through the surface and inside. It has the characteristic of purifying indoor air.

Further, the titanium oxide photocatalyst has a function of exhibiting a superhydrophilic phenomenon. In other words, the surface of a normal titanium oxide has hydrophobicity stabilized by cross-linking of oxygen between titanium atoms, but when this titanium oxide surface is irradiated with ultraviolet rays, some cross-linking oxygen falls off and oxygen defects are formed. This causes water in the air to dissociate and adsorb to produce chemically adsorbed water (hydroxyl groups), which becomes hydrophilic, and further, water molecules adhere to the hydroxyl groups as physically adsorbed water, so that the hydrophilicity is stably maintained. is there. Such super-hydrophilization imparts functions such as drip-proof, anti-fog, and self-cleaning with water.

The binder functions as a binder for the dried shirasu, the clay material imparts operational plasticity in construction on site, and the shirasu balloon makes the surface of the wall material soft and soft. .

On the other hand, the adhesion reinforcing agent improves the workability of the iron during construction and prevents powdering of the surface in a dry state. The sedges function as a binder material and a crack preventing material.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. Architectural finishing coating material 1 according to the present invention
As shown in FIG. 1, is composed mainly of dry shirasu A having a function of generating active oxygen species / free radicals described later. This dried shirasu A is unprocessed without any modification to itself, and is in its original form.
Then, the dried shirasu A is used as the building finish coating material 1 together with the binder B. The binder B is made of cement, gypsum, slaked lime, synthetic resin emulsion, or the like. In addition,
The dried shirasu A may be any one of the binder B, the clay material C, the shirasu balloon D, the adhesive reinforcing material E, the coloring pigment F, and the sasa G, or a combination of two or more of them. Used together with the ones.

The coating material 1 for building finish has a dry shirasu A of 50 to 65%, preferably 53%, and a binder B of 30%.
４０40%, preferably 35%, and clay material C is 3〜１０10%
4%, Shirasu balloon D is 5-10%, preferably 7%, adhesion reinforcing agent E is 0.08-2%, preferably 1%, and coloring pigment F is 0.01-3%. Is preferably formed by mixing 1% with Sasa G in an amount of 1 to 5%, preferably 2%.

Specifically, the dried shirasu A is adjusted to a particle size of about 5 mmφ or less by a screen sieve or the like, and dried after removing mixed impurities. As the binder B, for example, gypsum plaster or the like as a binder of the dried shirasu A is used. Clay material C is used to impart plasticity in operation. The shirasu balloon D is used to make the surface finish soft and soft.
The adhesive reinforcing agent E uses vegetable glue or the like in order to improve workability of the iron and prevent powdering of the surface in a dry state. This adhesive reinforcing agent E is, for example, 0.0% of cotton material.
3 to 1%, preferably 0.05%, for example, seaweed is boiled into powder, and 0.05 to 1% is preferably 0.0%.
It can be formed by mixing with 9% or the like. Sasa G
Uses, for example, hemp susa or straw susa as a binder material and a crack prevention material.

In the case of manufacturing as a ready-mixed raw material product, the dried shirasu A is 53%, the clay material C is 4%, the shirasu balloon D is 7%, the adhesion reinforcing agent E is 1%, and the coloring is performed. The pigment F is 1% and the sasa G is 2%, and they are prepared in advance as components and packed in a bag or a bottle. Also, 35% of the binder B is packed in a separate bag, mixed together at the construction site, directly added with water, kneaded, and applied with a trowel or the like.

Gypsum plaster as the above-mentioned binder B is a self-hardening cement having relatively high strength against shrinkage cracks and the like, and its main component is calcined gypsum. When this calcined gypsum is kneaded with water with hemihydrate gypsum, it undergoes a hydration reaction to obtain water of crystallization to become gypsum dihydrate, and then excess water other than water of crystallization diffuses and hardens. Gypsum plaster is made of calcined gypsum as a main raw material, a setting retarder is added by adding a setting retarder, and the setting time is adjusted, and river sand, silica sand, lightweight aggregate, calcium carbonate, etc. are mixed in advance with the on-site mixing plaster. There are pre-mixed plasters that can be used depending on the application.

The above-mentioned clay material C is a hydrated silicate mineral which exhibits plasticity when wet and exhibits rigidity when dried, such as silicon dioxide, aluminum oxide, iron oxide, magnesium oxide, calcium oxide, titanium oxide and the like. Is used as a component. It is particularly excellent in tackiness, plasticity and dispersibility, and has a pH of 5.9, a plasticity index of 22.1, and a viscosity of 74 μ97% Pass.

As the above-mentioned adhesive reinforcing agent E, natural cellulose (pulp fiber) is used as a raw material, and a part of the hydrogen atom of the hydroxyl group of the cellulose is substituted with a methyl group, a hydroxypropyl group or a hydroxyethyl group. Thus, a nonionic water-soluble cellulose ether, water-soluble methyl cellulose, hydroxymethyl cellulose, hydroxypropyl methyl cellulose, or the like, which has high water retention by eliminating hydrogen bonds and allowing water to easily enter between cellulose molecules, is employed. At this time, a clay grade material such as clay having a thickness of about 400 to 4000 mPa · s may be adopted so that the surface of the wall material is not made as shiny or glossy as possible.

Examples of the above-mentioned coloring pigment F include inorganic pigments and organic pigments having alkali resistance, and a mixture of some of them with inorganic and organic pigments. Cement, lime,
A desired color is exhibited by interposing or adhering between particles of gypsum plaster or the like. For example, titanium oxide, rutile type titanium oxide, chromium oxide, zinc oxide, lead white, barium sulfate, chalk, carbon, kaolin, talc, bentonite, red iron oxide, graphite, yellow iron oxide, black iron oxide, ferric oxide, Mineral blue, cobalt blue, cobalt violet, zinc chromate, and inorganic pigments such as siliconized products thereof, or organic pigments such as quinacridone, watch angred, dioxazine violet, etc. are coloring pigments F.
It is listed as.

Further, in order to impart more curability and adhesion to the dried shirasu A itself, the binder B is prepared in a ratio of 4 to 5 with respect to the dried shirasu A, for example. At this time, if the amounts of the binder B and the clay material C are too large and the viscosity is too strong, a small crack will be generated on the surface in the coated and finished state.
Should be kept as small as possible. And, since dried shirasu A itself widely ranges from coarse particles to fine particles,
For the purpose of enhancing the joining effect between particles, the occurrence of cracks is prevented by using sasa G as a reinforcing material described above.

Further, in order to impart plasticity to the dried shirasu A itself, the clay material C is prepared in a ratio of 1 to 1.7 with respect to the dried shirasu A, for example.

The dried shirasu A mainly has a large particle size.
Medium and small particle size, large particle size is about 2.3mmφ ~ 1.1mmφ, medium particle size is about 1.0mmφ ~ 0.2mmφ, small particle The diameter is about 0.1 mmφ or less. Then, about 5% of the dried shirasu having a large particle size and about 2%
By allocating 8% and small particle size to about 57%, it is possible to provide preferable materials for the architect's upper coating material 1 and the architect's upper panel 3.

Since silicic acid as a main raw material constituting the dried shirasu A itself has a property of being negatively charged, it is usually a cationic metal having a positive charge / aluminum, iron, magnesium, or the like. Includes titanium, manganese, etc., and furthermore, cations calcium, sodium,
Bonding to potassium or the like, and bonding to hydrogen to form a hydroxyl group having a negative charge, such as a silicate mineral having such a component constitution, it exists in nature in general. The substance fired by exposing this combined body to the high temperature of magma associated with volcanic activity is what is called shirasu. This mixture is a completely inorganic pure natural ceramic material with an extremely fine particle size distribution and a porous structure in the process of generation by high temperature. Has been generated as.

Further, since the apparent specific gravity is light (there are many gaps), it has the characteristics of excellent water absorption and water retention. It has high heat retention and heat insulation. Shirasu with these various characteristics is suitable for use as wall materials and building auxiliary materials. In addition, the extremely fine particle size distribution, which is one of the characteristics, realizes a much wider effective contact surface area when compared with a material having a coarser particle size distribution, and the material itself has an adsorptive property and a hygroscopic property. It has the effect of further enhancing the characteristics of.

Further, the porosity constituting the non-crystal occupying 70% of the material has an effect of multidimensionally increasing the contact surface area, and as a result, the contact surface area of the material is artificially generated. It has a structure that is so dense and deep that it is impossible to imagine the material. This leads, for example, to the fact that the use of porous ceramics as a high-performance filter medium in a centralized water environment filtration system is effective in advanced water treatment technologies, and it is thought that both design concepts are based on the same viewpoint. The use of Shirasu with such characteristics for wall materials is
It can be considered as a living environment air filtration.

In general, pure natural ceramic materials which have been completely inorganic and have been subjected to high temperature treatment have extremely neutral properties, and have other chemical species (for example, moisture, moisture,
There is no adverse effect (for example, oxidative alternation, reduction alternation, etc. due to a change in pH) on the physical properties of trace amounts of suspended matter or organic matter corresponding to dirt in the air. Therefore, since the contact object has the property of maintaining an environment in which short-term changes in physical properties / adhesion, solidification, sedimentation, deterioration, corrosion, decay, etc. are unlikely to occur, the living environment surrounded by such materials becomes more natural. Has the effect of maintaining. In this way, it is extremely suitable for a long-term use that is in close contact with a wall material or a living environment that is in direct contact with moisture or air for a long period of time.

The main component of the dried shirasu A is silicic acid / silicon dioxide (silica) having a composition ratio of 65 to 73%. Negatively charged silicic acid is a cationic metal / alumina, iron, magnesium, titanium, manganese, and positively charged cations such as calcium, sodium, potassium, etc. It forms a crystal and forms a so-called shirasu, but since these mixtures are produced at a high temperature by magma, they have special physical properties. In particular, shirasu balloons produced at high temperatures contain gas and have the properties of excellent heat retention and heat insulation properties, and this trait makes shirasu a wall material, building material, etc.
This is an important factor in using it as an auxiliary building material.

Silicic acid, which is known as a raw material for dehumidifiers such as silica gel, has a very high hygroscopic property and, when combined with potassium, has a strong water retention property as potassium silicate. It can also be used as a water retention material to protect the roots of local plants.

Further, alumina, which accounts for 12 to 16% of the component ratio of shirasu, is a chemical species fired at a high temperature, and has a characteristic that the porous structure having a large surface area has a very high water and gas adsorption power. In combination with the hygroscopic property of silicic acid and the hygroscopic and water-retentive properties of potassium silicate, it has an extremely high effect on dehumidification and humidity adjustment.

Further, titanium bound to silicic acid having a negative charge has a positive charge and is included as titanium oxide.
It reacts with hydrogen and humidity / moisture in air to generate active oxygen species, and exhibits various cleaning effects such as decomposition of organic substances dissolved in air and water and deodorizing effects accompanying decomposition of organic substances.

In addition, hydrogen in the shirasu component combines with oxygen to form a hydroxyl group / hydroxyl radical (.OH), and a superoxide anion is formed from water molecules and oxygen which come into contact in the process of exchange of high potential. radical(·
02 ^-) active oxygen species / free radicals, such as are generated. Since reactive oxygen species / free radicals have strong bactericidal and organic substance decomposing abilities, shirasu materials containing such a reaction system are highly effective in purifying, sterilizing and deodorizing air passing through the surface and inside. It has the characteristic of purifying indoor air.

In addition, the feature of the so-called titanium oxide photocatalyst that exerts organic substance decomposition and cleaning effects when titanium oxide, light and water are involved, for example, is that the electron-hole pair is formed by irradiating titanium oxide with ultraviolet rays. , Which reacts with oxygen or water in the air to generate superoxide ions or hydroxyl radicals having strong oxidizing power, which is well known as the so-called Honda Fujishima effect. Further, the titanium oxide photocatalyst has a function of exhibiting a superhydrophilic phenomenon. In other words, the surface of a normal titanium oxide has hydrophobicity stabilized by cross-linking of oxygen between titanium atoms, but when this titanium oxide surface is irradiated with ultraviolet rays, some cross-linking oxygen falls off and oxygen defects are formed. This causes water in the air to dissociate and adsorb to produce chemically adsorbed water (hydroxyl groups), which becomes hydrophilic, and further, water molecules adhere to the hydroxyl groups as physically adsorbed water, so that the hydrophilicity is stably maintained. is there. Such super-hydrophilization imparts functions such as drip-proof, anti-fog, and self-cleaning with water.

Next, an example of use of the present invention will be described. For example, at the construction site, dry shirasu A53%, binder B35%, clay material C4%, shirasu balloon D7%, adhesion reinforcing agent E1%, coloring pigment F1%, sasa G2% are already prepared and prepared as a composition. Water is directly added to the raw material product, kneaded, and applied with a trowel or the like. At this time, there is an advantage that the dried Shirasu A is easy to be colored because the original color is white gray, and for example, a commercially available ordinary plastering pigment can be used as the pigment coloring material. In addition, after finishing the pattern on the finished surface basically by applying a thickness of about 5 mm with a trowel or the like, and then checking the degree of curing, rubbing, scribing, holding down using a trowel, roller, comb, etc. It is formed by rolling. The coating material 1 for building finish can be widely applied to a wall finishing material in a room, a finishing material for an outer wall, a floor, a floor material, a ceiling, and the like. At this time, the coating material 1 for building finish may be applied using a trowel or the like, or may be sprayed using a spray gun or the like.
In addition, the brush may be applied using a brush or the like, and any means may be used.

Further, as shown in FIG.
Binder C, Clay C, Shirasu Balloon D, Adhesive Reinforcing Agent E, Color Pigment F, Sasa G are added with an appropriate amount of water and kneaded. Gypsum board, veneer board, concrete board, mortar-resistant plywood, asbestos An architectural finish panel 3 which is applied on a base material 2 such as a plate or the like and subjected to surface finish processing by various designs may be formed. Thus, the building finish panel 3
With this configuration, work on the construction site becomes extremely simple.

In particular, by utilizing the abundant natural resources of volcanic ash shirasu effectively in its original unprocessed form, the coating material 1 for architectural finish and the architectural finish, which embodies the natural softness and roughness of the shirasu's original features. Panel 3 can be formed.
In addition, it becomes a measure to prevent chemical sensitivity and a measure to prevent sick house, and it can be used as an alternative building material for depleted sand, saving energy, saving resources, reducing pollution,
In addition to detoxification and price reduction, inorganicity, extensibility, coloring,
Effective effects such as fire resistance, fire protection, sound insulation, humidity control, antibacterial, heat storage and heat insulation, deodorant, air permeability, etc. can be exhibited.

This is because the present invention uses a dry shirasu A material having a function of generating free radicals / active oxygen species composed only of natural materials in the original unprocessed form without using any chemical substance. It does not contain such chemical substances as it is a preventive measure against chemical hypersensitivity and a sick house preventive measure, and it can be used as a substitute for depleted sand as a building material, contributing to the construction of healthy houses. It can also contribute to revitalizing local industries in depopulated areas. In particular, it is almost neutral and has almost no adverse effect on the human body during construction. Furthermore, the occurrence of discoloration, stains, and the like of the wood at the pillars in the room and at the contact points such as the peripheral edge, the frame, and the baseboard are extremely small. Then, in the processing of the joint portion of the base board, it is possible to devise a device that does not cause cracks by merely attaching kraft paper to a width of about 5 cm. In addition, crack prevention
It can be achieved by adjusting the amount of sasa G which affects the permeation and drying of water during construction. Moreover, the coating material for architectural finish 1 is not likely to be peeled off without previously applying an adhesion reinforcing agent as a base treatment to the board surface as the base 2.

In addition, dried shirasu A having a function of generating active oxygen species / free radicals is very preferable as a finishing material for houses because it is porous, white, and lightweight.

%, Coloring pigment F 0.01-3%, sasa G 1-5%
Because of the composition, it is possible to easily create the coating material 1 for building finish without requiring large energy and cost such as electric power and fossil fuel at the time of raw material production and construction on site,
It does not cause pollution. In addition, because it is inorganic, it is resistant to ultraviolet rays and heat, and is also resistant to natural disasters such as fires, floods, typhoons, etc. In addition, Shirasu is porous, pumice-like and has breathability, condensing the house structure itself And the like, and can exhibit antibacterial properties for controlling humidity and controlling mold and the like.

The binder B functions as a binder for the dried shirasu A. Further, since the clay material C is made of a hydrated silicate mineral which exhibits plasticity when humid and exhibits rigidity when dried, plasticity can be imparted in various processes in operation. Then, the shirasu balloon D can make the finish of the wall material surface soft and soft.
Further, since the adhesive reinforcing agent E is made of nonionic water-soluble cellulose ether or hydroxypropylmethylcellulose, the workability of the iron can be improved, and the powder on the wall material surface can be dried in a dry state. It is possible to prevent the phenomena of formation, and to prevent adhesion to the human body, clothes, and the like. In addition, the sedges G can function as a binder material, and can also prevent cracking of the wall material.

On the other hand, an appropriate amount of water was added to the dried shirasu A, the binder B, the clay material C, the shirasu balloon D, the adhesive reinforcing agent E, the coloring pigment F, and the sasa G, and the mixture was kneaded, followed by gypsum board, plywood, When an architectural finish panel 3 that is applied on a base 2 such as a concrete board, a mortar-resistant plywood, or an asbestos board and subjected to a surface finishing process of various designs is configured, work at a construction site becomes extremely simple.

As described above, the present invention eliminates the so-called cracking phenomenon and water flow phenomenon of shirasu, which are mainly caused by the separation of water and shirasu, by mixing a highly water-retaining clay material or the like.
