Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to vitreous and crystalline vitreous materials embodying the grain pattern of natural wood.

[Prior Art] One of the inventors invented a method for manufacturing artificial wood having a wood grain pattern, which was disclosed in Japanese Patent Publication No. 54-950, and this method was formed from a thermoplastic resin sheet containing calcium sulfite or seccola. This synthetic artificial wood is made up of a spring wood layer formed by adding a coloring agent to the above material, and an autumn wood layer formed by adding a coloring agent to the above material, and has a texture similar to that of natural wood.

Furthermore, the same inventor succeeded in producing a ceramic material exhibiting a wood grain pattern, and filed an application as Japanese Patent Application No. 63-257073. This invention involves rolling up a laminate obtained by laminating a large number of ceramic clay plates with a coloring agent sprinkled on their surfaces or a band-shaped clay plate with a coloring agent sprinkled on their surfaces from one end to form a roll. The roll-formed product is cut in a desired direction before or after firing to create a wood grain pattern on the cut surface, and is used as a building material and a furniture material, respectively.

As is already widely known, vitreous materials are widely used in architecture, furniture, and even as various types of sheet glass for vehicle interiors.

Recently, so-called crystallized glass has been used as a material, and new uses have been developed for it as building materials, furniture materials, and even tableware materials. However, for these uses, conventional materials are provided in the form of glass plates, such as so-called corrugated glass with a pattern on its surface, and ground glass with a pattern on its surface.

In addition, the application of decorative patterns to general-purpose forms such as colored plate glass has finally reached a rut, and there are many people who are looking forward to the emergence of new decorative patterns.

This is true, for example, of crystallized glass building materials and furniture materials, which are used as new materials after the product name Neovarie. There are many areas where traditional coloring or surface pattern decoration is not enough.

Especially in recent years, as architecture has become more sophisticated, and furniture is also required to be of a higher level, it is no longer possible to satisfy user needs with conventional surface decoration or colored decoration alone. There is a growing demand for advanced decorative techniques.

[Problems to be Solved by the Invention] In order to meet the above requirements, the inventors believe that if a wood grain pattern can be applied to a transparent vitreous material, the transparency of glass can be used to create a new and deep pattern. Having come up with the idea that a cosmetic material could be obtained, we conducted repeated tests and research on the application of the above-mentioned method for producing a ceramic material with a wood grain pattern to vitreous materials and crystallized vitreous materials, and finally completed the present invention. .

[Means for Solving the Problems] According to the present invention, glass plates having different colors or appearances,
Or crystallized glass plates with different colors or appearances, or a flat plate in which the glass plate and the crystallized glass plate are arranged in an appropriate laminated manner, or a bottom plate whose surface is laminated, saddle-shaped, wavy, or has a desired uneven curved surface. Layer many sheets on top,
A wood grain pattern characterized in that the glass plate is held at a temperature above the softening point and below the melting point of the glass to soften the glass plate, make it have the same shape as the bottom plate, and fuse or crystallize each other to integrate. A roll containing a wood grain pattern, or a roll made by stacking two or more sheets and rolling them into a roll from one end under a softened state and maintaining the temperature at a temperature above the softening point and below the melting point of the glass. A vitreous material or a crystallized vitreous material is provided.

Furthermore, by cutting the above-mentioned laminate or roll-formed product along a predetermined plane, a vitreous material or crystallized glass material with a wood grain pattern exposed on the cut surface is provided.

First, the rectangular parallelepiped laminate shown in FIG. 1 will be explained.

Prepare a red, blue, white, or black colored glass plate or a colorless rectangular glass plate and use it. As shown in Figure 2, they are laminated on a flat bottom plate (1) in the following order: for example, a colorless plate - a colored plate - a colorless plate - a colored plate... In this case, the softening and melting temperatures of the colorless plate and the colored plate are measured in advance, and then heated to a temperature above the softening point and below the melting point of the glass material of the laminate, fused and integrally formed to form a wood grain pattern. An embedded vitreous laminate material is obtained. Note that it is convenient to place a weight during the fusion to assist the fusion.

Some examples of glass colorants are shown in Table 1 below.

Margin 1 below Colorants Blue, blue-green, yellow-brown Iron oxide green/red Copper oxide green/red-brown Manganese oxide dark blue Cobalt oxide blue-purple red Nickel oxide orange/yellow/green/dark green Chromium oxide yellow/yellow-brown
Sulfur yellow/yellow-brown Carbon yellow-green fluorescent color Uranium oxide Autumn leaves/yellow-green
Gold yellow/red yellow Silver yellow/orange/red/brown Selenium oxide The above laminate is a combination of a colorless plate and a colored plate, but each has two different colors.
It may be a combination of different types of colored plates, or a combination of transparent and opaque plates of the same color, a combination of dark and light colors, or a combination of plates with different colors and appearances, or a stack of two plates of the same color. An appropriate lamination arrangement can be adopted, such as stacking one layer of another color on top of this, and each layer can have its own unique decorative properties.

In addition to the above-mentioned combination of glass plates, it is of course possible to combine crystallized glass plates with each other, or with a glass plate and a crystallized glass plate, each of which should be laminated in an appropriate laminated arrangement as in the case of the above-mentioned glass plates. This gives it a unique appearance and texture.

The laminate itself can also be used as a material for finishing into arts and crafts by grinding or engraving.

As shown in Figure 2, the cut surface has a straight grain pattern by cutting the laminate along a parallel plane (A) parallel to the side surface of the laminate or an inclined plane (B) inclined at an appropriate angle. is obtained.

In addition, as shown in Fig. 3, a saddle-shaped bottom plate (2) with a medium-high surface is used instead of a flat bottom plate, and glass plates are laminated in the same manner as described above and heat-treated to integrate the saddle-shaped laminate. is obtained.

In addition, as shown in Fig. 4, a lance-shaped bottom plate (3) with a concave trough-like surface in the center is laminated, heat-treated, integrated, and turned upside down with the saddle-shaped laminate. A trough-like laminate of the same type is obtained. In addition to the above-mentioned bottom plate, a bottom plate having a desired uneven curved surface such as a corrugated shape can also be used.

Generally, by using a mold in which a side frame is provided on the side surface of each of the bottom plates, the layers are laminated in this mold, and a heat treatment is performed to avoid misalignment between the layers, and a preferable result can be obtained.

Next, in Figure 4, by cutting the laminate along a plane parallel to the side surface (A) and an inclined inclined plane (B), a straight-grained pattern is exposed on each cut surface, and the end surface and inclined By cutting along the plane (C), a cross-grain pattern can be obtained, and by cutting along the plane (D) parallel to the end face, a round pattern can be obtained.

Next, as shown in Figure 5, two glass plates with different colors or appearances, two crystallized glass plates, or a glass plate and a crystallized glass plate are stacked in two layers under a softened state and wound up from one end into a roll. A vitreous roll-molded product is obtained by molding and holding the glass at a temperature above the softening point and below the melting point to fuse and integrate the above-mentioned glass.

As shown in FIG. 6, the roll-formed body is cut along a plane (E) including the central axis to obtain a straight-grained pattern on the cut surface,
A grain pattern is obtained by cutting along a plane (F) inclined to the plane (E), and a plane (F) perpendicular to the plane (E) is obtained.
Cut along G) to obtain a cut surface with an annual ring pattern.

[Function] In the present invention, by utilizing the transparency of glass,
It has a deep wood-grain-like internal transparent pattern, giving it a high-grade decorative quality, and the cut and polished surface reveals a wood-grain pattern, giving it a decorative quality with a texture different from that of wood.

Furthermore, due to its transparency, it is possible to allow some light to pass through, so it can be applied to indoor lighting applications, similar to glass blocks.

Furthermore, compared to ceramics, the firing temperature is lower, the firing equipment is simpler, and the hardness is lower, so cutting and polishing is relatively easy.

[Examples] The present invention will be explained in more detail below using Examples.

Example 1 A glass plate having the chemical composition shown in Table 2 below was used.

Table 2 Chemical composition Weight % 5in2 71.0 Fe,,03+A 1203 1.0CaO8,0 Mg0 3 ,5 Na○ 15oO Total 98.5 2.5% copper oxide was added to the base glass having the above composition to create a red color. I made a prototype glass plate. In addition, a colorless and transparent glass plate containing only base glass was prepared.

Both types of glass plates were cut into rectangular glass plates measuring 100 mm x 200 mm x 6 mm, which were stacked and mounted on a bridge-shaped bottom plate made of stainless steel as shown in FIG.

The total number of sheets was 20, and one colorless plate and one colored plate were laminated alternately.

Place the 20-layer laminate together with the bottom plate in a furnace and let it cool to room temperature (
20℃) to 1200℃ over 10 hours,
After the laminate was held at 1200° C. for 30 minutes and adapted to the shape of the gutter, the power supply to the furnace was stopped, and it was allowed to cool in the furnace overnight and then taken out. The taken out laminate can be used as it is, for example, as a glass block product, or it can be cut along planes (A) and (B) to form straight-grained boards, as shown in Fig. 4.
Further cut along the plane (C) to create a grained board, and then the plane (D)
A circular plate was obtained by cutting along the . The straight-grained boards, cross-grained boards, and round-cut boards thus obtained all had the desired material properties and decorative properties, and were fully equipped as new high-grade materials.

Example 2 A white crystallized glass plate (100 mm
x 200mm x 8mm) and black crystallized glass plate (10
0 mm x 200 mm x 5 mm) was used.

4.2Co OO,3 100,0100,0 This plate was arranged in a laminated manner on the bridge-shaped bottom plate shown in FIG. The number of sheets was 10 white plates and 10 black plates, which were laminated one by one alternately.

Place the laminate together with the bottom plate in a furnace and heat from room temperature to 1050℃.
The temperature was raised over 7 hours to 1,050°C for 1 hour,
After the laminated body had sufficiently adapted to the shape of the gutter of the bottom plate, the power supply to the furnace was stopped, and the laminated body was allowed to cool to 100° C. in the furnace and then taken out.

Incidentally, although the above example is a case of glass plates that have already been devitrified, it is of course possible to laminate and integrate crystallized glass plates that have not yet been devitrified, and in that case, the temperature should be raised to 1050°C from room temperature. In the middle of the process, it is necessary to add a crystal nucleus generation process in which the temperature is maintained at 750°C for 2 hours.

The taken out laminate was used as a block-shaped product or cut in the same manner as in Example 1.

In this case as well, it has the desired material properties and decorative properties, and is fully equipped as a new high-grade material.

Example 3 The vitreous colorless transparent plate used in Example 1 (100 mm
200 mm x 6 mm) and the black crystallized glass plates (100 mm x 200 mm x 5 mm) used in Example 2 were stacked alternately, 10 each, as in Example 1, and placed on a gutter-shaped bottom plate and placed in a furnace. Pour in and heat from room temperature (20℃) to 120℃.
The temperature was raised to 0° C. over 10 hours, and held at 1200° C. for 30 minutes so that the laminate had a comb shape. After that, it was allowed to cool in a furnace overnight and then taken out.

The taken-out laminate has the desired material properties and decorative properties both in its original state and in its cut state, and is fully equipped as a new high-grade material.

Example 4 The colorless transparent glass plate used in Example 1 (300X900X6
mm) and red glass plates (300 x 900 x 3 mm) were stacked one by one to form two layers as shown in Figure 5, and placed in a furnace.
The material is heated to a temperature above the softening point and below the melting point to allow plastic deformation, in this example at 1200±5°C, and wound up from one end to form a roll-formed product, left to cool in a furnace overnight, and fused together. A fixed roll-formed body was produced.

From this roll-formed body, as shown in Fig. 6, the plane (E)
Cutting along the plane (F) produced a straight-grained board, cutting along the plane (F) produced a grained board, and cutting along the plane (G) produced a tree-ring board.

The straight-grained boards, cross-grained boards, and round-cut boards thus obtained all had the desired material properties and decorative properties, and were fully equipped as new high-grade materials.

[Effects of the Invention] The vitreous material having a wood grain pattern according to the present invention has the transparency of glass and the deep decorativeness that penetrates to the inside. In addition, when cut to reveal a wood grain pattern on the surface, it has excellent decorative properties due to the unique texture of glass, which is different from wood.

In addition to possessing the excellent material properties of vitreous materials, the firing temperature is lower than that of ceramic fired products, making firing equipment simpler, and its low hardness makes cutting and polishing easy, making it a new high-grade building material. , very useful as furniture materials, etc.
