In Japanese Patent Application No. 59-6126, the present inventor proposed an artificial stone with a natural pattern made from glass powder and a method for manufacturing the same. The artificial stone in the earlier application uses glass powder as a raw material and is fired under pressure, so it has gloss, hardness, and unnaturalness despite low pressure, and the pores between the glass powder particles are sealed, resulting in fine and uniformly distributed air bubbles. As a result, light is scattered, creating a stylish and calm appearance. However, if the glass powder is not sufficiently filled in the mold, large pores and bubbles may remain even when sintering under pressure, which may impair the appearance or cause a decrease in strength. .

おいては単に加圧成形してから焼結するので、加
圧成形時にガラス粉末の流動が悪く大粒の気孔を

とがある。 In addition, in conventional sintering of glass powder, the glass powder is simply pressure-formed and then sintered, so if the glass powder does not flow well during pressure-forming and leaves large pores, they may turn into large air bubbles. This can be a drawback.
本発明は前記したガラス粉末を加圧成形すると

An object of the present invention is to provide a method for producing a glass body free of large bubbles by eliminating the residual large pores that tend to occur when the above-mentioned glass powder is pressure-molded.
前記問題点を解決するため、本発明においては

In order to solve the above-mentioned problems, the present invention is characterized in that glass powder is pressed and molded in a mold while applying vibration in the presence of a liquid, and then sintered.

For example, when a glass powder mixed with an appropriate amount of water is left standing, the water is adsorbed on the surface of the glass powder, and the aggregate of the glass powder becomes a gel state, which has relatively high deformation resistance and has poor fluidity. Even when pressurized, it is difficult to achieve close packing. However, when vibrations are applied to the glass powder in this state, water is liberated and the glass powder becomes a sol with very good fluidity, and a close-packed state can be obtained with a small amount of pressure.
The present invention applies this thixotropy. When glass powder is in a dry state, it has relatively fluidity, but it does not reach the level of the present invention. For example, when granules are mixed with glass powder and molded, the gaps between the granules It is difficult to completely fill the glass powder with glass powder. Furthermore, in this case, since there is no liquid that acts as a binder, it is impossible to remove the mold from the mold before sintering, and a large number of molds must be prepared for mass production.
本発明の方法に用いるガラス粉末は揺変性を利

具体的には粒径200μm以下のものが20重量％以上

が、製品外観を与える点では種々の粒度に分布し
ているのが良い。 The glass powder used in the method of the present invention is preferably as fine as possible from the viewpoint of utilizing thixotropy.
Specifically, it is preferable that particles with a particle size of 200 μm or less contain 20% by weight or more. Furthermore, from the point of view of handling before sintering, it is better to have as fine and uniform a particle size as possible, but from the point of view of giving the product a good appearance, it is better to have a distribution of various particle sizes.

在した大理石調のガラス体が得られる。 Further, if the glass powder is granulated in advance in a state containing a liquid, and the granules are pressurized while being vibrated in a mold, the granules flow and deform, allowing close packing. Even in this case, the granules do not completely mix with each other, but only deform and form a close-packed state, so that a boundary line where the granules touch each other remains, which changes the appearance of the product. Using this effect, for example, you can prepare granules of glass powder mixed with pigments that produce white, red, and black colors, mix these three types of granules in a mold, and apply vibration pressure. After molding and firing, a marble-like glass body dotted with white, red, and black is obtained.

は、ガラス粉末粒径が大きくなる程小さくなる。 Liquids that can be mixed with glass powder include water, caustic soda, water glass, methyl cellulose,
Aqueous solutions such as polyvinyl alcohol or organic silicic acid compounds such as ethyl silicate are commonly used. Although water alone is effective as a binder for glass powder, if the strength of the molded product before firing is required, it is preferable to use a liquid other than water as described above. The amount of liquid to be added varies depending on the glass powder particle size and cannot be determined unconditionally, but when water is used as the liquid and the glass powder particle size is 100 μm or less, the glass powder exhibits thixotropy when the water content is 15 to 30% by weight. If the water content is more than 30%, it becomes slurry-like and cannot maintain its own shape even if it is left standing, and if it is less than 15%, it does not exhibit thixotropy and does not have good fluidity even if it is subjected to vibration. The range of water content for thixotropy becomes smaller as the glass powder particle size becomes larger.

ことで達成出来る。 There are no restrictions on the vibrations applied to the glass powder. The frequency range is from several tens to tens of thousands of rpm, and the amplitude is from several hundred μm to several cm.
However, if the vibration frequency is low, the glass powder will not easily fluidize unless the vibration width is increased. The direction of vibration may be either horizontal or vertical, but it is preferably horizontal to prevent the contents of the mold from spilling out. The applied pressure is sufficient to suppress the contents in the mold from springing up, that is, about 1 to 5 gr/cm 2 . The higher the pressure, the better the dehydration rate will be, but a press will be required when making large-area products. Several grams
r/cm 2 can be achieved by placing a drop lid that also serves as an upper mold.

This is done by heating to a temperature range that exhibits a viscosity of ~10 to 10 poise. Through this sintering, the glass powders are sintered or fused together to form a strong glass body.
Firing may be carried out while the glass powder molded product is in the mold, but in the present invention, the liquid acts as a binder, so it is possible to remove the mold and sinter it. can be accelerated.

Add 60g of Bengara powder and 900g of water to 6000g of 7500g of glass powder (r/cm 3 ), and add 30g of titanium oxide powder and 225g of water to the remaining 1500g. Mix each thoroughly and use an upper rotary granulator to make a powder of 3 to 15 mm. It was granulated to a particle size of Both of the above-mentioned granules were mixed uniformly in a mold with internal dimensions of 40 cm x 40 cm x 6 cm deep, with silicone oil applied as a mold release agent on the inner surface, and a mold with a thickness of about 1 mm was placed on top of the mold. The size allows you to cover the felt cloth, and also doubles as an upper mold and weight on top of it.
39.5cm x 39.5cm x 1.2cm thick iron plate length and width 5 each
Place a hole with a diameter of 1 cm on a cm pitch, fix the mold together on a vibration table, and set the vibration frequency to 9000 r.pm.
Vibration was applied with a width of 2 mm. When the vibrations started, water leaked through the felt through the holes in the upper mold, and air bubbles passed through the felt and floated to the surface of the water stored in the holes, which continued for a while. When the oozing water was removed by suction, the oozing of water and bubbles stopped after about 4 minutes of vibration, so the vibration was stopped after 5 minutes. The upper mold was removed, the felt cloth was peeled off, the mold was turned over and the glass powder preform was transferred onto an iron plate on which silica sand powder had been sprinkled as a mold release agent, and the glass powder preform was dried at room temperature for 2 days. Glass powder compact after drying is 40cm x 40
It had a thickness of cm x 2.1 cm, and was firm enough that it would not crumble even if you pressed it with your fingers. This is done in an electric furnace.
The temperature was raised to 650°C at a rate of 10°C/min, held for 1 hour, then raised to 750°C, held for 1 hour, and then cooled to room temperature at 1°C/min. The glass powders are sintered or fused together, and the resulting glass body measures 39.5 cm.
x 39.5 cm x 2 cm thick, the entire surface contains microbubbles of 0.05 mm or less uniformly, scattering incident light, giving it a soft luster. White background patterns are scattered within the red background pattern, and the border area is Since it was moderately blurred, it had the appearance of a polished surface of natural stone. Also, the diameter is 0.3mm
