Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention is based on the principle that gray shirasu is subjected to high-temperature chemical treatment and whitened as a main raw material. White shirasu contains titanium dioxide. It is extremely small and does not reach photocatalysis. However, due to its high porosity, the function of adjusting humidity is required, and it is used as the main raw material. By using this as an architectural finishing material mixed with an improved titanium oxide having a photocatalytic function, it is multifunctional and healthy. This enables the realization of a healthy indoor environment that takes into account the environment.

2. Description of the Related Art A conventional technique is Takachiho Co., Ltd.'s (Nakagirishima wall), which is made by drying naturally deposited Shirasu 80.
%, White cement 10%, gypsum 15%, reinforcing material 4% such as straw, sasa or hemp, and 1% pigment coloring material, add water, knead, apply surface treatment by various designs, and dry. Accordingly, there is a manufacturing method (refer to Japanese Patent Application Laid-Open No. 11-62053) for forming a plastering wall material for architectural finishing.

[0003]

As disclosed in Japanese Patent Application Laid-Open No. 11-62053 (Nakagirishimakabe) by Takachiho Co., Ltd., the main raw material is dried shirasu, which is naturally deposited like ash light, and titanium is used as the shirasu. Decomposes organic matter because it contains
Although it is said that it is deodorized, even if it is adsorbed, it does not cause catalytic action enough to lead to decomposition, and there is no scientific support. Titanium contained in Shirasu is only a trace amount, and has not yet been able to exhibit its photocatalytic function. In addition, general titanium oxide having a photocatalytic function decomposes organic substances in contact with a substrate, but hardly appears on a finished surface, and its utilization is limited, so that commercialization is difficult. Taking this as a contradiction, it was made of a completely inorganic material, and the improved titanium oxide was adopted to solve these problems and provide an excellent utilization means. In addition, if the finished surface is coated, the surface to be covered is small and the catalyst function can not be exhibited, so the surface to be covered increases by expressing the text chair by using a combination of iron and roller, brush, comb, etc., and the porosity becomes high, An excellent means capable of exhibiting a catalytic function was employed.

[0004] The amount of titanium contained in shirasu and the like is only a very small amount, and in order to exert a photocatalytic action, it is necessary to reinforce titanium oxide or the like for a catalyst. However, certain reinforcing agents have existed until recently. There was no problem.
In addition, the shirasu itself is gray in color, and it is extremely difficult to obtain various and vivid colors, so that the range of use as a product has been limited. By applying high-temperature chemical treatment (patented technology) and making it white, our company has secured the exclusive use right and made it the main raw material,
The design has been further enhanced, and a wide range of Japanese and Western uses has become possible.

[0005] In view of such circumstances, the present invention employs an improved titanium oxide having a photocatalytic function on white shirasu to decompose harmful chemical substances such as formaldehyde, which is a cause of bad odor and sick house syndrome. To provide a multi-functional building finish with improved functionality by adopting Metrolze (chemical glue) to facilitate construction and improve dispersibility, mixing vinylon chips etc. as a binder.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, one embodiment of the present invention will be described in detail. 55-70% of white shirasu, 15-40% of slaked lime, 15-30% of plaster, 5-15% of white cement, 0.1-3% of metroze to improve workability, vinylon chips of tie and reinforcing materials 1 to 3%, improved titanium oxide for exhibiting more photocatalytic performance 0.2 to 5%, inorganic pigment 0.1
５5%, water is added and kneaded, and using a finishing material for any architectural surface, the planar portion is finished by means of a combination of a trowel, a roller, a brush, a comb, etc., and spraying.

The finishing material of the present invention is obtained by kneading slaked lime, plaster, white cement, vinylon chips, improved titanium oxide, inorganic pigment, water, etc., using white shirasu as a main raw material. INDUSTRIAL APPLICABILITY According to the present invention, an improved type titanium oxide having a photocatalytic function has been developed, and it has become possible to use it as a product capable of exhibiting higher functions as a building finishing material. There is a problem with the workability of Takachiho's (Nakagirishima Wall), and the number of complaints is extremely high, making it easy to solve these problems. As a result, it became possible to contribute to society as a product that is health-friendly and meets the needs of society.

Here, the main raw material, shirasu, will be described. Shirasu was erupted and deposited as pyroclastic flows during an early volcanic eruption approximately thousands to tens of thousands of years ago, and exists nationwide but has a variety of particles. Etymology comes from Hakushu and Hakushu. This is the accent that became Shirasu at the Kagoshima dialect. Although the appearance of Shirasu and welded ashstone is remarkably different, the components are exactly the same. After deposition, the material melted by the pressure and heat of the ejecta and solidified again is welded ashstone, and the unwelded gray one is shirasu. Shirasu is 65-73% silicic acid and 12-
16%, iron 1-3%, lime 2-4%, soda 3
-4%, potash 2-4%, etc. As the size of the shirasu of the present invention, the strength and the porosity were determined, and therefore, a grain size of 0.03 to 6 mm is optimally adopted. In addition, because of its high porosity, it has a function of adjusting humidity. Because of these characteristics, the main raw material is Shirasu.

Here, the photocatalyst will be briefly described.
Photocatalysts are substances that cause various chemical reactions to the energy of light. However, the photocatalyst itself does not change,
Its function as a catalyst is semi-permanent. This photocatalytic effect was first discovered in the world in 1972 as an effect of decomposing organic substances in contact with various chemical reactions into hydrogen and oxygen by irradiating titanium oxide with sunlight or illumination light. Titanium oxide is a safe material used in various parts of our daily life as a raw material for cosmetics and white paints.

Here, titanium oxide will be described. The actually used shape of titanium oxide is roughly divided into two. This is a method in which the main material powder is mixed into a catalyst or mixed into an aggregate and fired. Both methods require major modifications and construction to be applied to existing facilities and construction. In addition, since titanium oxide, which is the main material, is another material, it has a disadvantage that it is difficult to be exposed on the surface after production, and the function of the catalyst is limited. There were significant restrictions on the range and conditions of the applicable substrate. For inorganic photocatalyst used in the present invention,
The improved titanium oxide solves these problems.

Since conventional titanium oxide decomposes organic substances in contact with it and also attacks the underlying substrate, its utilization is limited. In addition, it is difficult to appear on the production surface, and its utilization is limited

Here, the improved titanium oxide photocatalyst for photocatalyst will be described in detail. The improved titanium oxide compounded in Ashlite is a Jupiter series and Super Titania series jointly developed by the Nagoya Institute of Technology and Ministry of International Trade and Industry and Showa Denko. "Apatite composite titanium oxide fine powder for photocatalyst" developed based on titanium and super titania series. `` Japanese Patent Laid-Open No.
9 "," Japanese Patent Application Laid-Open No. 10244166 ",
342 ", the conventional titanium oxide for photocatalyst, when kneaded into organic fibers or plastics, also decomposed the medium itself, but the improved titanium oxide has an apatite crystal layer formed on the surface of the titanium oxide. It is a completely new type of titanium oxide for photocatalyst that does not decompose the medium and has protein adsorption ability. The improved titanium oxide adsorbs various malodorous components including living odors, harmful chemical substances, bacteria, and the like, and decomposes the adsorbed components with a photocatalytic function. The photocatalytic action is considered to be semi-permanent. The improved titanium oxide is an epoch-making one which is expressed under sunlight or a little light, and maintains an excellent catalytic effect for a long time in a living environment. "Characteristics" 1, Apatite is coated on the surface of anatase type titanium oxide fine particles having a particle diameter of 28-30 nm with a thickness of several A (coating amount: about 1% / titanium oxide) 2, Maintains high photocatalytic function 3, Fiber, paper, Does not decompose the medium even when dispersed in plastic, etc. 4. Supply of powder and slurry type in neutral pH range. (Characteristics, necessity) Adsorbs and decomposes formaldehyde to make it odorless. Adsorbs and decomposes three major odors in the living environment. Tobacco (ammonia, acetic acid, acetaldehyde, etc.) Garbage (trimethylamine, mercaptan, etc.) Toilet (mercaptan, ammonia, etc.) In addition, it absorbs and decomposes bacteria and various malodorous components to make it odorless. It performs its function under sunlight or lighting.

Titanium oxide, which has been conventionally recognized,
Differences in characteristics of the improved titanium oxide “Jupiter series, Super titania series” will be described. This improved titanium oxide is called "Apatite Composite Titanium Oxide Fine Powder for Photocatalyst" and
This is a joint development of Showa Denko KK, and the conventional titanium oxide photocatalyst shows a high effect, but at the same time attacks the organic base material. In addition, there is no action to attract bacteria,
Only contact material can be decomposed, does not work in the absence of light. However, improved apatite is not used for proteins, viruses such as influenza, Escherichia coli, ammonia,
It has an adsorption function for nitrogen oxides and is applied to functional masks and air purifier filters. However, there is a need for adsorption saturation exchange. A titanium oxide is deposited on the surface in a simulated body fluid by applying the property that apatite is produced in the body. The apatite crystal shape is a rose petal shape that grows vertically from the whole titanium grain sphere, and the titanium surface is also exposed. As a result, a property that compensates for the disadvantages of the two was obtained.
No functional difference due to the apatite deposition was observed, and the light amount was simulated under general home lighting, and the antibacterial test using Staphylococcus aureus and Escherichia coli showed a high sterilization rate. In the decomposition of acetaldehyde, the concentration decreased even in a light-shielded state, and apatite adsorption was confirmed. Even at night without light, the function is maintained. The apatite's adsorptivity enhances the adhesion to the substrate and simultaneously prevents the contact with the substrate, so that it can be applied to any material. There is the characteristic that the flexibility is maintained without disturbing the respiration of the base material, and there is no change in the color tone or the texture.

It should be noted that a very small amount of titanium contained in shirasu, which invades organic substances, is hardly exposed on the finished surface, and has a limited photocatalytic function. It is.

Next, a vinylon chip will be described.
Vinylon fiber is a synthetic fiber whose industrial production was started by domestic technology about 50 years ago, and has a history of being developed for various uses such as for industrial materials and clothing. It is widely recognized in industry and is now widely used for industrial materials.

(Characteristics and necessity) Good familiarity as a connecting material. The fractured surface is material-destructed and has high capture with aggregate. High adhesion of white volcanic eruptions, slaked lime, plaster, cement. High strength, high modulus, low elongation. Safety (no melt drop)

According to the present invention, an improved photocatalyst having 55-70% of white volcanic eruptions, slaked lime as a hardening agent, 15-30% of plaster, 15-30% of white cement, 5-15% of white cement, and a function of deodorizing and decomposing odors, is used. , 2-5%, splicing, reinforcing material vinylon chips 1-3%, chemical glue 0.01-1%, inorganic pigments 0-1-3%, functional, workability, design, health room The environment has been enhanced to enable the use of inorganic and healthful architectural finishing materials.
