- inorganic adhesives are conventionally known as adhesives having excellent heat resistance and fire resistance.
- this inorganic adhesive generally, a mixture of water glass or colloidal silica as a binder and an oxide such as alumina as a filler is known.
- inorganic adhesives that use water glass absorb water carbon dioxide in the air and gel silicic acid precipitates to form a glass that exhibits strong adhesive strength, such as glass and ceramics. It is used for adhesives and fireproof coatings.
- inorganic adhesives using water glass generally have a slow curing rate, there is a proposal to increase the curing rate by adding antimony pentoxide as described in JP-A-6-25610. ing
- the conventional inorganic adhesive has a problem that it is much more expensive than the organic adhesive because it uses an oxide such as alumina. For this reason, it cannot be used from the profit side in the field of architecture in which a large amount of adhesive is used, for example, the manufacture of plywood and the application of wallpaper.
- conventional inorganic adhesives have poor workability due to their slow curing speed, and have not been able to withstand use at construction sites that are often exposed to wind and rain. Therefore, the conventional inorganic adhesives are rarely used as adhesives or coating agents in the field of construction while having excellent heat resistance and fire resistance.
- the inorganic adhesive described in Patent Document 1 improves the workability by increasing the curing rate (drying rate), but using alcohol as a reaction aid for water glass and antimony pentoxide and stirring. Since the manufacturing process is complicated, such as the need for temperature control, it has become more expensive than before. Therefore, it could not be used in the field of architecture used in large quantities.
- the present invention has been made in view of such problems, and can be used as a heat-resistant and fire-resistant adhesive, paint, coating agent, filler or the like with good workability and low cost. It is an object of the present invention to provide a curable inorganic composition.

- a commercially available product can be used.
- water glass is, for example, JIS K1408 No.
- Fly ash is, for example, coal ash collected with a dust collector from the combustion gas of a pulverized coal combustion boiler of a coal-fired power plant. Ash particles produced when pulverized coal is burned in a pulverized coal combustion boiler floats in a high-temperature combustion gas in a molten state, and then cools at the boiler outlet to become spherical fine particles. These spherical fine particles are fly ash, and the composition thereof is, for example, 40.1 to 74.4% by weight of SiO 2 (silicon dioxide, silica), 15.7 to 7% of Al 2 O 3 (aluminum oxide, alumina). 35.2 wt%, Fe 2 O 3 (iron oxide) 1.4 to 17.5 wt%, MgO (magnesium oxide) 0.2 to 7.4 wt%, CaO (calcium oxide) 0.3 It is ⁇ 10.1% by weight.
- SiO 2 silicon dioxide, silica
- Al 2 O 3 aluminum oxide, alumina
- fly ash is ash generated by high-temperature combustion in a boiler or the like, and almost no flammable component remains, so mixing it can improve the heat resistance and fire resistance of the curable inorganic composition. Furthermore, since fly ash is a spherical fine particle, the fluidity
- the curing speed and storage stability are balanced, and the storage stability is maintained while increasing the curing speed. Making it possible. Further, it is possible to increase the long-term strength and adhesive strength of the cured inorganic composition.
- fly ash Since fly ash is produced in large quantities as a by-product of a coal-fired power plant, it can be purchased at a much lower price than silica and alumina, and commercially available products can be used.
- the fly ash has a particle size of 45 ⁇ m or less ( For example, it is preferably 1 to 45 ⁇ m), and more preferably 30 ⁇ m or less (for example, 1 to 30 ⁇ m).
- Fly ash having a particle size of 45 ⁇ m or less or 30 ⁇ m or less can be obtained using, for example, a 45 ⁇ m sieve or a 30 ⁇ m sieve. It is needless to say that all the fly ash particle diameters are not necessarily 45 ⁇ m (30 ⁇ m) or less, and some of them may be 45 ⁇ m (30 ⁇ m) or more.
- fly ash is, for example, JIS A6201 type II (the proportion of SiO 2 is 45% or more, the 45 ⁇ m sieve residue is 40% or less, and the brain method Specific surface area by 2500 cm 2 / g or more) or type I (SiO 2 ratio is 45% or more, 45 ⁇ m sieve residue is 10% or less, and specific surface area by the brain method is 5000 cm 2 / g or more). Those are preferred.

- the metal oxide having a particle diameter of 45 ⁇ m (30 ⁇ m) or less can be obtained by using, for example, a sieve, and a part of 45 ⁇ m (30 ⁇ m) or more may be included as in the above fly ash. It is.
- the metal oxide is not limited to the above-described zinc oxide, and oxides of other metals such as magnesium, calcium, iron, and boron can be used. Moreover, only one type of metal oxide may be used, or a plurality of types of metal oxides may be used.
- zircon flour is further mixed in addition to the above components.
- This zircon flour is powdered zircon (zirconium silicate, ZrSiO 4 ) obtained by mechanically pulverizing and dividing zircon sand. Since zircon flour has a high melting point and low thermal expansion, it contributes to improving the heat resistance and fire resistance of the curable inorganic composition. Furthermore, since zircon flour is insoluble in water, it contributes to improving the water resistance of the curable inorganic composition.
- zircon flour since zircon flour has an effect of lowering the glass softening point of mixed glass, it can increase flexibility and prevent embrittlement when the curable inorganic composition is vitrified by heating. . Thereby, for example, when a curable inorganic composition is used as a fireproof coating, it is possible to improve the retention of the coating film during heating and prevent it from peeling off easily.
- Zircon flour can be purchased relatively cheaply than silica and alumina, and commercially available ones can be used, but in order to mix well and disperse homogeneously in the composition, particles Those having a diameter of 45 ⁇ m or less (for example, 1 to 45 ⁇ m) are preferable, and more preferably, the particle diameter is 30 ⁇ m or less (for example, 1 to 30 ⁇ m).

- the production of the curable inorganic composition of this embodiment is based on 100 parts by weight of water glass, 25 to 35 parts by weight of fly ash, 15 to 25 parts by weight of zinc oxide, and 5 to 15 parts by weight of zircon flour. Are mixed by stirring in a container.
- the ratio of fly ash to 100 parts by weight of water glass is preferably 25 to 35 parts by weight from the viewpoint of the balance between curing speed and stability of the curable inorganic composition.
- the fly ash ratio is less than 25 parts by weight, the curing rate decreases, and when it exceeds 35 parts by weight, stability during storage deteriorates and long-term storage becomes difficult, which is not preferable.
- the ratio of the metal oxide with respect to 100 parts by weight of water glass is not particularly limited, and the ratio can be appropriately determined so as to have a viscosity according to the use of the curable inorganic composition. Further, the ratio can be appropriately determined according to the type of metal oxide to be used.
- the ratio when zinc oxide is used as the metal oxide is preferably 15 to 25 parts by weight with respect to 100 parts by weight of water glass from the viewpoint of obtaining an appropriate viscosity for obtaining good workability.
- a curable inorganic composition when using a curable inorganic composition as a putty or a filler, 25 parts by weight or more of zinc oxide may be added to 100 parts by weight of water glass.
- the ratio of zircon flour to 100 parts by weight of water glass is not particularly limited, but is preferably 5 to 15 parts by weight from the viewpoint of obtaining appropriate fire resistance and setting an appropriate glass softening point.
- a small amount of water for example, about 1 to 15% by weight may be added.
- a known method can be used as the mixing method. Mixing can be performed at room temperature. Furthermore, by thoroughly mixing the components and leaving them in a cool and dark place for about 1 day in a sealed container, the properties of the composition are stabilized, and predetermined viscosity and gloss appear.
- the obtained curable inorganic composition has 22 to 40% by weight of silicon dioxide (SiO 2 ), 10 to 15% by weight of zinc oxide (ZnO), and 3 to 15% of sodium oxide (Na 2 O) as components. Containing 3 wt%, aluminum oxide (Al 2 O 3 ) 3 to 10 wt%, zirconium oxide (ZrO 2 ) 2 to 8 wt%, and water. From the viewpoint of balance and workability, 25 to 36% by weight of silicon dioxide, 12 to 13% by weight of zinc oxide, 6 to 11% by weight of sodium oxide, 5 to 6% by weight of aluminum oxide, It is more preferable if it contains 4 to 5% by weight of zirconium oxide and water.
- water glass is a commercially available cement hardening agent
- fly ash is JIS standard type II
- zinc oxide is JIS standard type 1
- zircon flour is 98% or more
- particle size is 45 ⁇ m or less. I used one.
- the obtained composition was a gray viscous liquid, and could be spread thinly on the surface of various materials with a spatula or a brush, and it was confirmed that the composition had good workability.
- the obtained composition has a specific gravity of about 1.8 and a pH of about 12.2, and the components and contents thereof are 25 to 36% by weight of SiO 2 , 12 to 13% by weight of ZnO, Na 2 O was 6 to 11% by weight, Al 2 O 3 was 5 to 6% by weight, and ZrO 2 was 4 to 5% by weight.
- the obtained composition when used as an adhesive and vinyl wallpaper is attached to a wooden plywood and the wallpaper is continuously heated with a gas burner for 2 minutes (about 800 ° C.), the heated portion of the wallpaper is carbonized. There was no change in the plywood alone. Moreover, when it heated with the gas burner continuously for 3 minutes, only the heating part of wallpaper and the plywood carbonized, and the plywood did not spread. This is because the curable inorganic composition of the present example is vitrified and foamed by heating to form a heat-insulating incombustible layer between the wallpaper and the plywood, thereby preventing the plywood from spreading. That is, by using the curable inorganic composition of this example as an adhesive for plywood and wallpaper, it was possible to impart fire resistance to these building materials.
- the curable inorganic composition of the present invention can be manufactured at a lower cost than conventional inorganic adhesives without deteriorating quality and function by using fly ash. For this reason, it can be used as an adhesive excellent in heat resistance and fire resistance even in a field where inorganic adhesives have not been used so much in terms of cost as in the field of construction.
- the curing rate is increased and good workability is provided, so that it can be widely used as a coating agent, paint, filler, etc. in addition to the adhesive. .

- the curable inorganic composition of the present invention vitrifies and foams when heated, and forms a heat-insulating incombustible layer. Therefore, it is applied to various building materials and structural materials as an adhesive or coating agent. The fire resistance of these members can be improved and the spread of fire during a fire can be prevented.
- the curable inorganic composition of the present invention as a binder for a molded product, a fire resistant board having excellent fire resistance can be produced.
- curable inorganic composition according to the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the gist of the present invention.
