- the method of producing the organic-inorganic hybrid glassy material of the present invention is basically the method referred to as conventional sol-gel method, and also the new method proposed by the applicant including melting and aging. It is different.
- the conventional sol-gel method several kinds of sol-gel raw materials are mixed, stirred at room temperature for several hours, and then allowed to stand at room temperature for 2 days and 1 week to obtain a wet gel. After that, it is dried at room temperature-about 100 ° C for several hours-13 days to make a dry gel, and if necessary, it is crushed. • Washing 'After filtration, it is usually sintered at least 500 ° C and usually 800 ° C or more. Let them form balta and fiber. In the case of a membrane, it is formed into a thin film in the form of a wet gel, and dried and sintered to obtain a thin film.
- the present invention by mixing the sol-gel raw materials and adding the heating reaction step, it is possible to obtain the raw materials that can be directly melted without the need for the gelation step. That is, direct solification is achieved from the mixing step, and direct melting is achieved by concentrating the sol. The point not to cause gelation and direct melting of the melt are It is also quite different from the new zonore gel method and the new method involving melting and aging of the dried gel.
- the time required for this heating reaction step is about 30 minutes to 15 hours, it takes 13 days for gelation, and the conventional sol-gel method, the above-mentioned new method, and the method It is characterized by the manufacturing characteristics that the processing time is largely different, and the characteristic by the large product difference that an organic-inorganic hybrid glassy material having a lower softening temperature can be obtained even if almost the same sol-gel raw material is used.
- the melting step may be started immediately after the heating reaction step, or the melting step may be started after cooling once. Furthermore, it is also possible to change from the mixing step to the heating reaction step by carrying out under appropriate conditions.
- the ripening referred to in the present invention is completely different from the ripening referred to in the conventional sol-gel method. That is, the term "aging" refers to standing for obtaining a wet gel over 2 days and 1 week, but rather refers to an operation of changing the structure of the organic-inorganic hybrid glass after melting and stabilizing the glassy substance.
- the term "aging" refers to standing for obtaining a wet gel over 2 days and 1 week, but rather refers to an operation of changing the structure of the organic-inorganic hybrid glass after melting and stabilizing the glassy substance.
- the zonore gel method which has been conventionally performed, since the dried gel which is not subjected to the above-mentioned melting step is sintered as it is, there is no subsequent aging step.
- This ripening step is extremely important, and even a glassy substance having melting properties can not obtain a desired organic-inorganic hybrid glassy substance without passing through the subsequent ripening step.
- Starting materials are metal alkoxides, metal acetylacetonates, metal carboxylic acids, metal hydroxides, or metal halides, and it is preferable to first prepare a sol in the same manner as the sol-gel method.
- This starting material is not limited to the above-mentioned starting materials, as long as they are used in the sol-gel method other than the above. However, preparation of this sol is an important first step.
- a catalyst is preferably used.
- conventional catalysts are Although there is no problem with the alkali catalyst and the acid catalyst used in the Rugel method, ammonia is preferred as the alkali catalyst, and hydrochloric acid and acetic acid are more preferred as the acid catalyst.
- the starting material preferably has a metal unit having an organic functional group. If you do not have a metal unit, it will sinter but not melt.
- n is a natural number and is selected from among 1, 2, and 3. Furthermore, in particular, it is more preferable to have a phenyl metal unit (Ph 2 SiO 2), Also, methyl group
- the organic functional group R is typically a aryl group or an alkyl group.
- the aryl group include a phenyl group, a pyridinole group, a tolyl group, and a xylyl group, and a phenyl group is particularly preferable.
- the alkyl group include a methylole group, an ethyl group, a propyl group (n-, i-one), a butyl group (n-, i-one, s-, t-one), a pentyl group and a hexyl group (number of carbon atoms: 1-20) And the like, and particularly preferred are a methyl group and an ethyl group.
- the organic functional group is not limited to the above-mentioned alkyl group and aryl group.
- the alkyl group may be linear, branched or cyclic. From the above point of view, it is preferable to use at least one kind of zonolegel raw material containing a phenyl group.
- the metal unit of a phenyl group (Ph SiO 2)
- the metal unit of a methyl group (Ph SiO 2)
- Me SiO 2 Metal (Me SiO 2), an ethyl metal unit (Et 2 SiO 2), and a butyl metal such as n (4-n) / 2 n (4-n) / 2
- the upper limit temperature of the heating reaction step is an alcohol having a boiling point exceeding 100 ° C., for example, a 1-butanol having a temperature of 118 ° C. and a force boiling point of 100 ° C. or less. Therefore, it is better to consider the boiling point. For example, when using ethanol, its boiling point If the temperature is below 80 ° C, the result tends to be better. This is considered to be due to the fact that when the boiling point is exceeded, the alcohol evaporates rapidly and it becomes difficult to achieve a uniform reaction from the alcohol amount and the change in state.
- the heating reaction step may be performed in an open system or may be performed under reflux conditions.
- a stabilized organic-inorganic hybrid glassy material can be obtained through the heating reaction step, the melting step and the aging step.

Furthermore, this ripening temperature is extremely less effective at a temperature lower than the melting lower limit temperature. In general, it is desirable that the melting lower limit temperature be about 1 (melting lower limit temperature + 150 ° C.). Furthermore, it takes 5 minutes or more to mature.
- the ripening time depends on the amount processed, the treatment temperature and the permissible residual amount of reactive hydroxyl groups (mono-OH), but generally it is extremely difficult to reach a satisfactory level in less than 5 minutes. In addition, since productivity will decrease in a long time, it is preferably 10 minutes or more and 1 week or less. In addition, in the case of ripening, 2 of the first ripening performed at a temperature of 40 ° C. to 230 ° C. and a pressure of 0.1 Torr or less and the second ripening performed at 70 ° C. to 350 ° C. under atmospheric pressure. It may be divided into two steps.
- the process can be shortened by performing under an inert atmosphere or under reduced pressure, which is effective.
- microwave and ultrasonic heating are effective for shortening the time, but are also effective for improving mechanical characteristics such as strength and hardness and electrical characteristics such as dielectric constant.

- the method of the present invention has a major feature in melting, it often occurs that the melt after the melting step is separated into two layers. In such a case, it is necessary to discard the so-called supernatant liquid located above the two layers and extract the lower melt to obtain an organic-inorganic hybrid glassy substance which is stable in terms of physical properties if it is matured. You can By taking this method, an organic-inorganic hybrid glass-like substance generally having a low soft temperature can be obtained. Even in the case of separation into two layers, it is possible to mature as it is, but in that case, optical characteristics such as light transmittance also tend to be somewhat low.

- the softening temperature is preferably 500 ° C or less.
- the softening temperature exceeds 500 ° C., not only the desired organic-inorganic hybrid glassy material can not be obtained because the organic group bonded to the metal element forming the network during melting burns but it also breaks or generates air bubbles. Become opaque.

To become Desirably, it is 100 degreeC or more and 300 degrees C or less.
- the raw material of the second feature described above is used in the sol-gel method, but by adding a heating reaction step after the mixing step, the step which has conventionally been gelled over 13 days is omitted. It is possible to do S. It is preferable to perform heat treatment at a temperature of 40 ° C. to 100 ° C. and for 30 minutes to 10 hours.
