本発明は、建築用外装材、内装材として使用される模様
を有する結晶化ガラス建材の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for manufacturing a crystallized glass building material having a pattern, which is used as an exterior material or an interior material for construction.
（従来の技術）
結晶化ガラス建材の好適な製造方法として集積法が特公
昭５５−２９０１８号公報に開示されている。(Prior Art) A stacking method is disclosed in Japanese Patent Publication No. 55-29018 as a preferred method for manufacturing crystallized glass building materials.
この方法は、溶融した結晶性ガラスを水冷などにより急
冷した後、適当な大きさに破砕してガラス小体を得、こ
のガラス小体を平板成形用型枠に集積充填し、軟化点以
上の温度で熱処理して、ガラス小体を互いに融着して一
体化させると共に種々の方向の針状結晶を形成させる方
法である。In this method, molten crystalline glass is rapidly cooled by water cooling, etc., and then crushed to an appropriate size to obtain glass corpuscles.The glass corpuscles are then packed in a mold for forming a flat plate, and are heated to a temperature above the softening point. This is a method in which the glass bodies are heat-treated at a high temperature to fuse and integrate the glass bodies and form needle-shaped crystals in various directions.
（発明が解決しようとする問題点）
しかしながら、集積法には大形の結晶化ガラスが得難く
、またガラス小体を形成する原料ガラスが特定の性質を
有するものでないと通用できないという欠点がある。(Problems to be Solved by the Invention) However, the accumulation method has the disadvantage that it is difficult to obtain large-sized crystallized glass, and it cannot be used unless the raw material glass for forming the glass bodies has specific properties. .
すなわち、型枠に集積されたガラス小体を加熱していっ
た場合、ガラス小体の軟化融着の前に結晶の成長による
粘性の増大が生じると、粘性の増大によって小体相互間
の融着が困難となる。更に温度を上げて融着一体化を図
ろうとすれば、結晶が破壊もしくは転移して結晶化ガラ
スにならない。In other words, when glass bodies accumulated in a mold are heated, if viscosity increases due to crystal growth before softening and fusion of the glass bodies, the increase in viscosity will cause fusion between the bodies. It becomes difficult to put on the clothes. If an attempt is made to further raise the temperature to achieve fusion and integration, the crystals will be destroyed or transferred and crystallized glass will not be formed.
それ故、大形の結晶化ガラスを製造し難く、またガラス
小体を形成する原料ガラスは、結晶の成長速度が遅く、
結晶の析出する温度ではガラス小体同士の融着一体化が
可能な低い粘性を有するものでなければならない。換言
すると、結晶の成長がガラス小体同士の融着一体化温度
より高温で盛んになるようなものでなければならないの
である。Therefore, it is difficult to produce large-sized crystallized glass, and the raw glass that forms glass bodies has a slow crystal growth rate.
It must have a low viscosity that allows the glass bodies to be fused and integrated at the temperature at which crystals are precipitated. In other words, the crystal must grow at a higher temperature than the temperature at which the glass bodies are fused and integrated.
このため、原料ガラスとして、核形成剤もしくは核形成
作用を有する着色剤を含むガラスは、本質的に適さない
ものであり、限られた色調のものしか得られないという
欠点がある。For this reason, a glass containing a nucleating agent or a coloring agent having a nucleating effect is essentially unsuitable as a raw material glass, and has the disadvantage that only a limited color tone can be obtained.
また、集積法によって製造した結晶化ガラスは、その表
面を研摩した場合でも、内部に入射した光がガラス小体
の粒界で反射することによってわずかに粒界が認められ
る程度で、全体として無地のものであり、建材としての
経済的価値に劣るのが実情である。In addition, even if the surface of crystallized glass manufactured by the integrated method is polished, only slight grain boundaries can be seen due to the reflection of the light incident inside the glass bodies at the grain boundaries, and the crystallized glass is plain as a whole. The reality is that it has inferior economic value as a building material.
本発明はかかる問題点に鑑みなされたもので、種々の色

法を提供することを目的とする。The present invention was made in view of such problems, and an object of the present invention is to provide a method for easily manufacturing crystallized glass building materials in which patterns having various colors and tones are exposed, regardless of the size thereof. With the goal.

るものである。(Means for Solving the Problems) The present invention, which has been made to achieve the above object, is capable of precipitating wollastonite crystals, and a powder having a particle size of 200 mesh or less has a particle size structure of 70 mesh or more. Using the glass powder for forming and the glass powder for base formation, the partition frame 2 having a large number of partitioned filling holes 11 is attached to the mold 1, and the mold has the desired pattern holes 18, 18a and 18b formed therethrough. After placing the plates 19.19a and 19b on the partition frame 2 and filling the filling holes 11 directly below the pattern holes 1B, 18a and 18b through the pattern holes 18.18a and 18b, the pattern forming glass powder is filled with the pattern forming glass powder. Plate 19.19a
, 19b is removed and the filling hole 1 is not filled with powder.
1 is filled with glass powder for base formation, the partition frame 2 is removed, the powder is compacted, and then a crystallization heat treatment is performed.

着が比較的低温で容易に行われる。(Function) Using a pattern-forming glass powder and base-forming glass powder that can precipitate wollastonite crystals and have a particle size composition of 70% by weight or more of fine powder of 200 mesosinus or less, such glass powder is molded. Since the glass powder is compacted after being filled into a mold, the glass powders are easily softened and fused together at a relatively low temperature by subsequent heat treatment.
すなわち、成形型内のガラス粉末は各粉末が広い面積で
互いに緻密に接触しているから、軟化点に到達すると、
各粒子は容易に軟化し、融着一体化が比較的低温で行わ

化を図ることができる。In other words, the glass powder in the mold is in close contact with each other over a wide area, so when it reaches its softening point,
Each particle is easily softened, fused and integrated at a relatively low temperature, densification progresses, and then crystal growth can be promoted to achieve crystallization.
従って、大形の結晶化ガラス建材も容易に成形すること

。Therefore, large-sized crystallized glass building materials can be easily formed, and unlike the integrated method, there is no need to use a specific crystalline glass as a raw material for glass powder, and the raw material glass can be selected relatively freely. I can do it. In particular, any colored glass powder containing a customary coloring agent having a nucleating effect can be used as the patterning glass powder.

形成することができる。In addition, a partition frame having a large number of partitioned filling holes is attached to the mold, and the glass powder for pattern formation passes through the pattern holes of the template placed on the partition frame and enters the filling holes directly below it. Since the glass powder for pattern formation is filled in a predetermined position, a desired pattern can be repeatedly and easily formed in the mold.
そして、模様形成用ガラス粉末の充填後、型板を除去し

必要に応じて適宜数製作することができる。After filling the pattern-forming glass powder, the template is removed, and the unfilled holes are filled with the base-forming powder, the partition frame is removed, and the powder is compacted. A green compact with an integrally formed pattern is obtained. At this time, as mentioned above, the patterned part is filled with pattern-forming glass powder in a predetermined position using a template, so it is possible to produce an appropriate number of green compacts with the same pattern as needed. .

（実施例）
まず、本発明に使用する基地形成用ガラス粉末と模様形
成用ガラス粉末とについて説明する。(Example) First, the base-forming glass powder and the pattern-forming glass powder used in the present invention will be described.

であって、２００メツシュ以下の粉末が７０重量％以上

である。These glass powders are obtained by pulverizing glass raw materials that have a composition that allows the precipitation of wollastonite crystals, and have a particle size composition in which powder of 200 mesh or less accounts for 70% by weight or more, and both have a different color tone. It is different.

よる緻密充填を十分行い、かつ熱処理による粒子相互の
軟化融着を容易に行えるようにするためである。その結
果、結晶化が容易にかつ速やかに行うことができる。The above particle size structure is achieved by compacting the glass powder after placing it in a mold and filling it as described later. At this time, the compacted powder is sufficiently densely packed and the particles are easily softened and fused together by heat treatment. This is to make it possible to do so. As a result, crystallization can be performed easily and quickly.
基地形成用ガラス粉末と模様形成用ガラス粉末とを異な
った色調にするには、ガラス中の着色剤の種類やその含
有量に差を設けることにより行えばよい。例えば、基地
形成用ガラス粉末を無色とした場合、模様形成用ガラス
粉末を有色とすればよい。In order to make the base-forming glass powder and the pattern-forming glass powder different in color tone, this can be done by providing a difference in the type and content of the coloring agent in the glass. For example, when the base-forming glass powder is colorless, the pattern-forming glass powder may be colored.
無色ガラス粉末としては、例えば下記組成（単位重量％
）のものを例示することができる。As a colorless glass powder, for example, the following composition (unit weight %)
) can be exemplified.

Oxide powders such as
5% by weight is preferred. If it is less than 0.1%, the degree of difference in color tone is small and it is difficult to tell them apart. On the other hand, if it exceeds 5%, the difference in the shrinkage rate of the crystallized part of each powder becomes large during the crystallization heat treatment, and cracks occur at the boundary. occurs.
次に、前記ガラス粉末を用いて、模様付の結晶化ガラス

。First, as shown in FIG. 1, the partition frame 2 is attached to the mold 1. The mold 1 is composed of a lower mold 7 consisting of a side mold 5 having a molding hole 4 and a bottom plate 6, and an upper mold that is slidably fitted into the molding hole 4, although not shown. ing. on the other hand,
As shown in FIG. 2, the partition frame 2 has a large number of partition plates 10 made of thin iron plates or plastic plates assembled vertically and horizontally to form a large number of square filling holes 11. . Of course, the planar shape of the filling hole 11 is not limited to the illustrated example, but may be rhombic or triangular as shown in FIGS. 3(1) to 3(3).
六角形状等から模様デザインに応じて適宜のものを選択

異なった色調のものを用いることは当然である。Next, a case will be described in which each filling hole 11 of the partition frame 2 is filled with various pattern-forming glass powders to form a rectangular overlapping pattern shown in FIG. 4. In the figure, 13 is a square pattern filling part, 14 is an upper overlapping pattern filling part, 15 is a lower overlapping pattern filling part, and 16 is a base filling part. It goes without saying that the pattern-forming glass powder filled in each part is of a different color tone.

成した後、成形型１から仕切枠２を除去する。First, as shown in FIG. 5, a template 19 having a rectangular pattern hole 18 formed therethrough is placed on the upper surface of the partition frame 2,
Glass powder for forming a pattern is filled into the filling hole 11 immediately below the pattern hole 18 through the pattern hole 18, thereby forming the square pattern filling portion 13. After filling is completed, this template 19 is removed, and a pattern hole 181 is formed in the same manner with the upper overlapping pattern shown in FIG.
The upper overlapping pattern filling part 14 and the lower overlapping pattern filling part 15 are sequentially formed using a template 19a having a pattern hole 18b having a pattern hole 18b shaped like the lower overlapping pattern shown in FIG. . Then, after filling the last remaining unfilled hole with base-forming glass powder to form a base-filled portion 16, the partition frame 2 is removed from the mold 1.

き結晶化ガラス建材が得られる。This heat treatment mainly consists of a primary heat treatment in which each powder is fused together at a low temperature, followed by a secondary heat treatment performed at a higher temperature. The secondary heat treatment is to grow the crystal nuclei generated at the fused interface by the secondary heat treatment, and rapidly crystallize the entire fused body. By this crystallization heat treatment, a patterned crystallized glass building material in which mainly wollastonite crystals are precipitated is obtained.

ス建材の品質向上に寄与することができる。Here, the term "normal temperature" includes a state where the material is preheated to a temperature lower than the -fire treatment temperature. In some cases, the secondary heat treatment is performed on the compressed and fused body obtained after hot pressing the glass powder at the temperature of the primary heat treatment in the mold. In this case, it is possible to omit powder compaction before heat treatment and the addition of a binder for powder compaction, which can contribute to improving the quality of crystallized glass building materials.
