The aerogels may be used as the main thermal insulation material in the insulation material 400 according to the present invention.

The airgel is formed by gelation of an alkoxide, a halide, or an organic compound of a metal by a method such as hydrolysis or polymerization to produce an alcogel, replacing the organic phase in the resulting alcohol with a solvent such as alcohol or carbonic acid gas, Further, it is a substance obtainable by extracting the solvent contained in the gel into a supercritical state and extracting it out of the gel, and it is a porous body having a skeleton of aggregates of fine particles.

However, the airgel has drawbacks of high hygroscopicity and low mechanical strength. The high hygroscopicity of the airgel is attributable to the fact that the silanol groups present in large amounts on the surface of the particles which become the skeleton of the aerogels tend to adsorb moisture. Also, the reason why the airgel is loose is that the -O-Si-O- bond forming the skeleton of the airgel is comparatively weak.

In the present invention, in order to obtain an airgel having a low hygroscopicity and an excellent mechanical strength, the present inventors have conducted intensive research and have found that (a) alkoxide or halide of silicon, (b) alkoxysilane and (c) An aerogel having low hygroscopicity and excellent mechanical strength can be obtained by using a compound represented by the following formula (1) or (2) as an alkoxysilane in an aerogel produced by supercritical drying of a wet alcohol gel formed by hydrolysis of a halide.

The heat insulating material of the present invention may preferably have a coefficient of thermal expansion greater than 8 x 10 &lt; ^-6 &gt; / K. In addition, the heat insulating material of the present invention can have a high phase stability up to 1350 ° C or higher. The thermal conductivity of these perovskites is less than 3 W / m / K, which is particularly advantageous for use as a heat insulating material. Further, the melting point of the heat insulating material of the present invention is generally 2000 ° C or higher, and a part thereof may be 2500 ° C or higher. All of these properties indicate that the above-described materials are very suitable for use as a heat insulating material.

Of the above-mentioned heat insulating materials, Ba (Mg _1/3 Ta _2/3 ) O ₃ is particularly preferable. _{Furthermore, Sr (Al 1/2 Ta 1/2)} O 3, Ca (Al 1/2 Nb 1/2) O 3, Sr (Sr 1/3 Ta 2/3) O 3, Sr (La 1/2 Ta _1/2 ) O ₃ can be preferably used. These materials have a melting point of about 3000 ° C.

In the heat insulating material 400 according to the present invention, the blending amount of the heat insulating material represented by the formula 7 or 8 may be, for example, 0.5 to 30 parts by weight based on 100 parts by weight of the base resin.

Further, by using CaH ₂ O ₂ , Na ₃ O ₄ P and NH ₃ in the present invention, a strong heat insulating action can be imparted. Further, by adding a white or pale color pigment, a sufficient heat-insulating performance and effect can be obtained by the reflectance. Further, since the above-mentioned additive components dissolve and become widespread, and the heat insulating effect acts as a whole, the conventional performance can be further improved. Such a material can be used as an auxiliary insulating material in the insulating material 400 according to the present invention.

In the present invention, CaH ₂ O ₂ dissolves about 30 wt% of its component by adding Na ₃ O ₄ P, but it can be dissolved in 100 wt% by adding NH ₃ . CaH ₂ O ₂ has a strong adiabatic effect, which can be completely dissolved, so that it is possible to mix easily into the composition.

Since the additive components of the present invention are excellent in the heat insulating performance of the material itself, the heat insulating performance can be exhibited even when the heat shielding function is cut off. For example, even when the color is changed to dark color, Performance can be achieved.

Baehapryul for obtaining CaH ₂ O ₂ in the present invention is Ca (OH) ₂ 75% by weight, CaO 23% by weight, CO ₂ 0.95% or less, SiO ₂ 0.15% or less, Al ₂ O ₃ 0.10% or less, Fe ₂ O ₃ is a CaH ₂ O ₂ composition in less than 0.2%, MgO 0.60% or less.

CaH ₂ O ₂ is used for improving soil in agriculture and used as an anticorrosion agent in industry, and it is widely used for ground line and food addition. It is noted that the present invention is excellent in refractivity and heat resistance in properties as well as in its inherent uses, and that the material itself is difficult to absorb heat. And can be made completely melted for application to a composition for making a sheet. However, no application of CaH ₂ O ₂ as an insulating material has been found so far.

CaH ₂ O two euros ₂ were not put into practical use as a heat insulating material, CaH ₂ O ₂ exerts a heat insulating effect to a state that is not only a small amount dissolves in water, that are not discarded is a particulate suitable for combination with a composition that is insoluble And the physical properties such as strength and the like are lowered. However, by adding Na ₃ O ₄ P in an amount of about 0.7 to 2% by weight and NH ₃ in an amount of 0.9% by weight or less, CaH ₂ O ₂ is completely dissolved and can be an aqueous solution having high purity in a transparent state. The blending amount of Na ₃ O ₄ P is preferably from 0.7 to 2% by weight, and it is not effective when it is out of the above range. NH ₃ is more than 0.9% by weight, the above range is sufficient, since the composition may be deteriorated.

The total amount of CaH ₂ O ₂ , Na ₃ O ₄ P and NH ₃ added in the heat insulating material 400 according to the present invention is preferably 3 to 30 parts by weight based on 100 parts by weight of the base resin. It is possible to exhibit the most stable heat insulating function within such blending range. If the added amount of the above components is too small, improvement of the heat insulating performance can not be expected. On the contrary, if the added amount of the above components is too much, the degree of improvement of the heat insulating performance is not improved anymore and other properties may be deteriorated. Accordingly, the heat insulator 400 according to the present invention is preferably blended within the above-mentioned range. Since the adiabatic component dissolves, the mixing itself is easy.

Further, in the present invention, by using LaB ₆ and / or SnO ₂ and Sb ₂ O ₅ as the heat insulating filler, physical properties such as weather resistance and heat insulation can be improved. Such a material can be used as an auxiliary insulating material in the insulating material 400 according to the present invention.

In the present invention, as an adiabatic filler, one kind selected from among LaB ₆ (pentane lanthanum) and antimony doped tin oxide (SnO ₂ + Sb ₂ O ₅ , hereinafter abbreviated as ATO), which can effectively shield near- Or two types can be used in combination.

In the heat insulation of sunlight, it can contribute to heat insulation by selectively or effectively shielding or absorbing near infrared rays of about 780 to 2100 nm. It is also preferable to shield ultraviolet wavelength region of 320 nm or less.

The spectrum of LaB ₆ fine particles has a large absorption peak near a wavelength of 1000 nm, so that it is possible to efficiently absorb or shield near infrared rays, thereby effectively shielding the thermal energy of sunlight. The absorbency of ultraviolet rays having a wavelength of 320 nm or less can be controlled by controlling the addition amount of LaB ₆ fine particles in the composition for sheet production. As described above, the heat insulating material of the present invention using LaB ₆ fine particles as a filler can efficiently absorb or shield the near-infrared region of the sunlight to impart heat insulating properties, and can absorb the ultraviolet region of wavelengths of 320 nm or less have.

When it is necessary to control the absorptivity of the ultraviolet ray region, the ultraviolet ray shielding inorganic material, organic material, organic-inorganic composite material such as cerium oxide, titanium oxide, zirconium oxide, zinc oxide, benzophenone- . &Lt; / RTI &gt; In addition, since the inorganic material-based ultraviolet absorber has the possibility of generating electrons and holes on its surface when ultraviolet light is absorbed, thereby deteriorating the resin composition, it is preferable to coat the surface thereof. As the surface coating treatment, various coupling agents, surface modifiers, sol-gel silicates and the like can be used.

As for the spectrum of ATO fine particles, a high heat insulating effect can be obtained because it has an absorption peak in a near infrared ray region of 800 nm or more in wavelength, and can be shielded even in an ultraviolet ray region with a wavelength of 320 nm or less. For this ATO, an inorganic material for shielding ultraviolet rays, an organic material, and an organic-inorganic composite material can be added in order to control the absorption rate of the ultraviolet ray region similarly to LaB _{6. In the} inorganic material-based ultraviolet absorber, It is possible to perform the surface coating treatment. As described above, the heat insulating material of the present invention having the ATO fine particles as the heat insulating filler can have a high heat insulating effect by absorbing or shielding the near infrared ray region, and also absorbs the ultraviolet ray region.

It is also possible to use LaB ₆ and ATO together as the heat-insulating filler, and more effective heat insulation characteristics can be obtained by using both pillars together. That is, as described above, since LaB ₆ has a large absorption peak at a wavelength of around 1000 nm and ATO gradually absorbs in a wavelength region of 800 nm or more, both of the fine particles are dispersed in the composition for sheet production, The absorption or shielding effect of the near infrared region is further increased as compared with the case of using it, and higher heat insulating characteristics can be obtained.

Since the heat insulating material of the present invention comprising LaB ₆ and / or ATO fine particles as an insulating filler is an inorganic material, it can obtain high weather resistance as compared with an organic material and is particularly excellent as a heat insulating material for a window which is usually exposed to the outside.

The particle diameter (including aggregated particles) of the heat-insulating filler is not particularly limited, and may be, for example, 10 nm to 10 탆. Methods for controlling the particle diameter of the heat insulating filler are various. When the particle diameter is made small, methods such as a ball mill, sand mill, ultrasonic treatment, collision grinding and pH control can be used. Particularly, when fine particles having a particle diameter of 200 nm or less are dispersed, it is possible to disperse the particles in a stable state by using various coupling agents, dispersants, and surfactants, and the dispersed particles after the treatment can be stably maintained.

When the LaB ₆ and / or ATO fine particles as the heat insulating filler are mixed with the resin composition, the particle diameter of the fine particles can be controlled by the above-described method, if necessary. Further, since fine particles of LaB ₆ and ATO are thermally stable, they can be kneaded even at a temperature near the melting point of various resins (about 100 to 300 캜).

The amount of LaB ₆ and / or ATO fine particles is generally preferably 50 parts by weight or less based on 100 parts by weight of the base resin, considering the workability in kneading and molding. The content of the heat insulating filler can be changed according to the specification of the window and the desired heat insulating property.

Since LaB ₆ has a high heat insulating efficiency per unit weight, an effective heat insulating effect can be obtained when the content per square meter of area is 0.01 g or more. In addition, it is possible to absorb or shield the heat energy of about 90% of sunlight at 1 g / m 2, sufficient effect can be obtained in summer heat insulation, and further addition is not preferable considering the warming effect in winter. Therefore, the content of LaB ₆ is preferably in the range of 0.01 to 1 g / m 2.

In the case of ATO, the content of about 3 g per 1 m 2 of area can absorb or shield the thermal energy of about 30% of the sunlight. Generally, an insulating effect is insufficient at less than 1 g / m &lt; 2 &gt;, and a cost exceeding 50 g / m &lt; 2 &gt; Therefore, the content of ATO is preferably in the range of 1 to 50 g / m &lt; 2 &gt;.

Hereinafter, the present invention will be described in more detail by way of examples. However, the following examples are intended only to illustrate the present invention, but the scope of the present invention is not limited thereto.

[Example 1]

1. Manufacture of aerogels

16.0 g of tetraethoxysilane and 2.0 g of? -Glycidoxypropylmethyldiethoxysilane were added to 50.0 g of ethanol and stirred well. To this was added an aqueous solution consisting of 9.0 g of water, 1.0 g of aqueous ammonia (1.0 mol / l) and 1.0 g of aqueous ammonium fluoride (0.1 mol / l). When the mixed solution was adequately hydrolyzed, 0.5 g of titanium tetra-n-butoxide was added and stirred, followed by further uniformly dispersing by ultrasonic waves. Then, it was transferred to a glass chalet, and the temperature was kept at 25 캜 to gel. The resulting alcohol gel was taken out and cured in ethanol. In order to diffuse the moisture in the alcohol gel at the same time as the curing, the molecular sieve was added to ethanol. Then, after the water content in the alcohol gel became 0.2 wt% or less, the alcohol gel was immersed in dehydrated isopentyl acetate, and the alcohol in the alcohol gel was replaced with isopentyl acetate. The alcohol gel thus treated was placed in a critical-point dryer and the apparatus was sealed. In this, carbon dioxide was introduced to pressurize and liquefy, and isopentyl acetate was diffused into carbon dioxide and discharged together with carbon dioxide to the outside of the critical point dryer. After the isopentyl acetate was exhausted, the critical point dryer was sealed, heated and simultaneously pressurized to bring the temperature and pressure above the critical point of carbon dioxide. Thereafter, the pressure and temperature were lowered to normal pressure and room temperature, and then the airgel was taken out. In order to compare the moisture resistance of the airgel produced in this manner, the amount of water absorption was measured by standing at an ambient temperature of 40 ° C and a humidity of 80% for 48 hours, which was 1/3 or less of the airgel made of only silicon. The compressive stress was measured as the strength of the airgel, and the stress at the time of 25% compression was about four times that of the airgel made of only silicon.

Next, the above-prepared composition was put into a mixer, kneaded uniformly, and then a transparent insulation material having a thickness of 10 mm was prepared through calendering.

To this, an aqueous solution obtained by mixing 8.0 g of water and 1.0 g of ammonia water (1.0 mol / l) was added. When the mixed solution was appropriately hydrolyzed, 0.3 g of aluminum tri-sec-butoxide was added and stirred, and further uniformly dispersed by ultrasonic waves. Then, the mixture was transferred to a glass chalet, allowed to stand at a temperature of 25 ° C, gelled, and immersed in methanol. Then, the critical-point dryer was charged with methanol, the alcogel was allowed to stand, and the critical-point dryer was sealed. Then, nitrogen gas was sealed in the critical point dryer, and the pressure was increased to about 70 kg / cm &lt; 2 &gt;, and then the apparatus was heated to 280 DEG C at a rate of 15 DEG C per hour. At this time, the pressure was adjusted to 235 ° C to maintain the pressure at 80 kg / cm 2. When the temperature of the apparatus reached 235 ° C, the pressure valve was closed to close the vessel, and then the temperature was raised and the pressure was increased until the methanol reached a critical state. After maintaining the critical state for about 2 hours, the pressure was gradually reduced while maintaining the temperature above the critical temperature, and when returning to the normal pressure, the apparatus was cooled and the airgel was taken out. The airgel thus produced was allowed to stand in an environment of a temperature of 40 DEG C and a humidity of 80% for 48 hours to measure the moisture absorption amount, which was 1/3 or less of the airgel made of only silicon. The compressive stress was measured as the strength of the airgel, and the stress at the time of 25% compression was about 5 times that of the airgel made of only silicon.

To this, an aqueous solution obtained by mixing 7.0 g of water and 1.0 g of ammonia water (1.0 mol / l) was added. When the mixed solution was adequately hydrolyzed, 0.5 g of zirconium tetra-n-butoxide was added and stirred, followed by further uniformly dispersing by ultrasonic waves. Then, it was transferred to a glass chalet, and the temperature was kept at 25 캜 to gel. After the produced alcogel was taken out, supercritical drying was carried out in the same manner as in Example 1 to obtain an airgel. The airgel thus produced was allowed to stand in an environment of a temperature of 40 DEG C and a humidity of 80% for 48 hours to measure the moisture absorption amount, which was 1/3 or less of the airgel made of only silicon. The compressive stress was measured as the strength of the airgel, and the stress at the time of 25% compression was about three times that of the airgel made of only silicon.

This reaction was carried out in a nitrogen atmosphere. 32.5 g of ethanol and 2.9 g of? -Methacryloxypropyltrimethoxysilane were added thereto and further stirred, and then an aqueous solution obtained by mixing 8.2 g of water and acetic acid was added to hydrolyze the mixture. Then, 5.4 g of ethanol was added to 0.4 g of titanium tetrachloride and stirred well. Then, ammonia was passed through the mixed solution, and the mixture was distilled to obtain titanium tetraethoxide. This reaction was carried out in a nitrogen atmosphere. The titanium tetraethoxide thus obtained was added to the appropriately hydrolyzed solution of the tetraethoxysilane, stirred, and then uniformly dispersed by ultrasonic waves. Then, it was transferred to a glass chalet, and the temperature was kept at 25 캜 to gel. After the produced alcogel was taken out, supercritical drying was carried out in the same manner as in Example 1 to obtain an airgel.
