I have come. Polymer materials and low-melting glass have different physical properties, so they have been used according to the environment in which they can be used. Generally, glass is used when heat resistance and airtight performance are prioritized, and organic materials such as polymer materials are used in fields where properties other than heat resistance and airtight performance are prioritized. However, with the recent technological progress, attention has been paid to characteristics that have not been required so far, and development of materials having such characteristics is expected.
- Low-melting glass such as O-SnF glass

- materials having heat resistance and air-tightness which are the characteristics of general molten glass, and easily obtaining various characteristics, such as polymer materials, are demanded in many fields. Expectations are gathered.
- organic-inorganic hybrid glasses are attracting attention as one of the low-melting glasses.
- Low-melting glass is typically represented by, for example, Sn—Pb—P_F_ ⁇ glass (see Non-Patent Document 1).
- Tick glass is widely used in some markets because it has a glass transition point around 100 ° C and exhibits excellent water resistance.
- the low-melting glass contains lead as its main component, it has become necessary to replace it with alternative materials in the current trend of environmental protection.
- the characteristics required for Tick glass have changed significantly, and the demands have diversified.
- the melting method is a method of melting glass by directly heating glass raw materials to produce vitrification. Many types of glass are produced by this method, and low melting glass is also produced by this method. However, in the case of low melting point glass, there are many restrictions on the glass composition that can be configured, such as the need to contain lead, alkali, bismuth, etc. in order to lower the melting point.
- a sol-gel method As a low-temperature synthesis method of amorphous barta, a sol-gel method, a liquid phase reaction method, and an acid-base reaction method are considered.

- the porous material may be used due to decomposition and combustion of organic substances such as alcohol introduced during preparation of the raw material solution, or evaporation and release in the heating process of the decomposition gas of organic substances or water.
- organic substances such as alcohol introduced during preparation of the raw material solution, or evaporation and release in the heating process of the decomposition gas of organic substances or water.
- the liquid phase reaction method has a problem in that productivity is low due to low yield, and in addition, the use of hydrofluoric acid or the like in the reaction system and the limitation of thin film synthesis are limited. It is almost impossible to synthesize a Balta body.
- the anhydride-base reaction method is a technique developed in recent years, and it is possible to produce an organic-inorganic hybrid glass, which is one of low-melting glasses (see Non-Patent Document 3), but it is still in the process of being developed. Yes, not all low-melting glass can be manufactured.
- low-melting glasses have been produced by a melting method rather than a low-temperature synthesis method. For this reason, the composition of the glass is limited due to the melting of the glass raw material, and the types of low-melting glass that can be produced are extremely limited.
- low-melting glass is a promising material because of its heat resistance and airtightness, and required physical properties are often obtained in a form typified by low-melting glass.
- the material is not limited to low melting point glass, but if the required physical properties are met, there is no major problem with low melting point or low softening point substances other than glass.

Furthermore, it can be used as a substitute for glass and ceramics that are used under processing conditions of 400 ° C or higher, or used for a long time in an atmosphere of 400 ° C or higher.
- the raw material before the heat treatment needs to have fusibility.
- the term “meltability” literally refers to the property of melting, that is, the property of drastically lowering the viscosity by heating to form a so-called molten state. Without this melting property, neither melting nor aging can be performed.
- the heat treatment performed after the melting of the raw materials or after the melting and aging is preferably performed at a temperature 100 ° C. or higher than the melting temperature.
- the main purpose of melting is to homogenize the raw material, the aging is to slowly change the structure of the entire raw material, and the subsequent heat treatment is to change the specific bond.

Further, for example, when performing the heat treatment at 500 ° C. or more and less than 550 ° C., the heat treatment time is preferably within 3 hours. If the heat treatment is performed for more than 3 hours, the organic functional group may be decomposed, and a good glassy substance cannot be obtained. In this case, the time is more preferably within 1 hour, and further preferably within 30 minutes. These conditions differ depending on the required specifications of light transmittance in the infrared region and other regions, the type of organic functional groups, and also the conditions under which coloring is permitted. There are many.
- the method of the present invention is characterized in that the reaction yield of silanol groups, that is, the yield related to the reaction from silanol groups to siloxane bonds is extremely high.
- the reaction yield when producing organic-inorganic hybrid glass (low-melting glass) by the conventional sol-gel method is limited to about 95% even when aging is performed at 200 ° C for 1000 hours, for example. Methods of over 95% have not been known so far. However, according to the method of the present invention, the reaction yield can be made close to 100% in a short time. This 5% difference is large. If the silanol group can be completely removed, an organic-inorganic hybrid glass with a low dielectric constant can be obtained, and further application as an insulating layer can be expected.
- the present invention is an organic-inorganic hybrid glassy substance produced by the above method.
- it is preferably an organic-inorganic hybrid glassy substance having an average transmittance at 800 to 2100 nm in terms of a thickness of 3 mm of 75% or more.
- the average transmission in the infrared region, especially in the wavelength range of 800-2100 nm The rate is extremely high.
- Conventional organic-inorganic hybrid glass generally contains an organic substance in the glass, so light absorption by organic groups and OH groups in the infrared region is a power whose light transmittance was never high. Can be obtained.
- the ratio of T 2 units and (D unit + T 3 unit + T 2 units + T 1 unit) is 1 hereinafter 0..
- the ratio of T 2 units and (D unit + T 3 unit + T 2 units + T 1 Yuni' g) exceeds 0.1, the amount of light absorption in the infrared region increases.

- the softening temperature is a force that tends to change by the treatment.
- the final softening temperature is preferably 100 to 300 ° C, more preferably 120 to 280 ° C. At the same time, it is necessary to have fusibility. Without this melting property, it is a force that often causes problems in the adhesiveness required for infrared transmitting materials.
- the softening temperature of the organic-inorganic hybrid glassy material was judged from TMA measurement at 10 ° CZmin. That is, the shrinkage was measured under the above conditions, and the temperature at which the shrinkage started to change was defined as the softening temperature.
- the rate of decrease in light transmission due to absorption of silanol groups is preferably 10% or less. If the rate of decrease in light transmittance due to the absorption of silanol groups exceeds 10%, for example, the selectivity factor in optical communication and the like will decrease, and its utility value will decrease.

- the raw material is produced as follows. That is, the starting material is a metal alkoxide, and a raw material produced through a heating reaction step, a melting step, and an aging step after a mixing step of the metal alkoxide and water, an acid catalyst, and an alcohol as the starting material is preferable. According to this method, its stability is high, and it can be manufactured at low cost while maintaining good quality. Next, a method having at least three steps of a gel body manufacturing step by a sol-gel method, a melting step by heating, and an aging step is preferred. Useful raw materials can be obtained by this method, but there is a problem in that productivity is reduced because the gelation step requires 11 to 13 days. What is important here is that it is meltable and cannot be produced by the conventional sol-gel method that does not have meltability.
- the upper limit temperature of the heating reaction step is alcohol having a boiling point exceeding 100 ° C, for example, when using 1-butanol at 118 ° C, the power is 100 ° C or less. It is better to do. For example, when ethanol is used, it is better to set the boiling point to 80 ° C or lower, which tends to give better results. This is because alcohol evaporates rapidly above the boiling point, making it difficult to achieve a uniform reaction due to the amount of alcohol and changes in state. It is thought to be because it becomes.
- the melting step is preferably performed at a temperature of 30 ° C to 400 ° C.
- the melting process by heating is performed in the temperature range of 30-400 ° C. At temperatures lower than 30 ° C, practically no melting is possible. If the temperature exceeds 400 ° C., the desired organic-inorganic hybrid glassy material cannot be obtained because the organic group that binds to the metal element forming the network burns, and furthermore, it becomes opaque due to crushing and bubbles. Or become. Desirably, it is 100 ° C or more and 300 ° C or less.
- the treatment is preferably performed at a temperature of 30 ° C. or more and 400 ° C. or less and a pressure of 0.1 Torr or less.
- a temperature of 30 ° C. or more and 400 ° C. or less and a pressure of 0.1 Torr or less At temperatures below 30 ° C., ripening is virtually impossible. If it exceeds 400 ° C, it may be thermally decomposed, making it difficult to obtain a stable glassy substance. Desirably, it is 100 ° C or more and 300 ° C or less.
- the lower limit of melting temperature is preferably about 1 (lower melting temperature + 150 ° C). At this time, it is preferable that the heat treatment is performed simultaneously at a pressure of 0.1 lTorr or less.
- the time required for ripening should be more than 5 minutes.
- the aging time varies depending on the amount of treatment, the treatment temperature and the allowable residual amount of reactive hydroxyl groups (1 OH), but it is generally extremely difficult to reach a satisfactory level in less than 5 minutes.
- the productivity decreases over a long period of time, so it is preferable that the period be 10 minutes or more and 1 week or less.
- the organic-inorganic hybrid glassy substance of the present invention cannot be obtained because there is neither the above-mentioned melting step nor aging step.
- the step may be performed under an inert atmosphere.
- Microwave heating is also effective.
- hydrochloric acid or nitric acid is often used as a catalyst. This is
- the gelling time is prolonged.
- hydrochloric acid or acetic acid which is preferable for nitric acid and other acids. More preferred
- Trifluoroacetic acid is also useful.
- the metal alkoxide as a raw material is an alkoxysilane substituted with an organic substituent, Organic substituents such as phenyl, methynole, ethyl, propyl (n-, i-), butyl (n-, i-, t-), pentyl, hexyl, octyl, decyl, dodecyl Group, octadecyl group, mercaptomethyl group, mercaptopropyl group, 3,3,3-trifluoropropyl group, 3_trifluoroacetoxypropyl group, butyl group, benzyl group, styryl group, etc.

- the power is not limited to these.
- ammonia it is also effective to use ammonia in the mixing step. At this time, it is preferable that the amount of ammonia used is 120 times higher than that of hydrochloric acid or acetic acid in molar ratio.
- Ammonia, hydrochloric acid and acetic acid are all catalysts and can be combined with ammonia and acetic acid or ammonia and hydrochloric acid, and ammonia alone does not show good results. If the molar ratio of ammonia used in the mixing step is less than 1 times that of hydrochloric acid or acetic acid, the alkoxide will not be completely hydrolyzed, leaving a large amount of T 2 (—OEt) in the glass and poor chemical stability. I do.
