Description

【0001】
【産業上の利用分野】
本発明は、金属的な煌めきを持ち、装飾性に優れた建築用ガラス物品と、その製造方法に関するものである。
【0002】
【従来の技術】
建築物の形状や装飾の多様化に伴って、デザインの面から建築物の一部に、装飾性を有するガラス物品が使用されることが多くなってきている。
【0003】
この種の建築用ガラス物品としては、型板ガラス、着色ガラス、特殊塗料を焼き付けたファッションガラス、網入・線入板ガラス等が市販されている。また最近では、透光性樹脂に多数の石材を混入した建築材料(例えば特許文献1)や、ガラス内部に多数の気孔を有する建築材料(例えば特許文献2)も提案されている。
【0004】
【特許文献1】
特開平5−279509号公報
【特許文献2】
特開2001−180953号公報
【0005】
【発明が解決しようとする課題】
ところで近年、ホテルのロビーに設置されるパーティションには、できるだけ高級感を出すことが望まれ、例えば透明感があり、しかも金属光沢を持つパーティションが要求されている。
【0006】
しかしながら従来の装飾性を有する建築用ガラス物品は、その要求を満足するものではない。つまり型板ガラスは表面に凹凸形状を形成して装飾し、着色ガラスは採色で装飾し、ファッションガラスは形状と採色で装飾したものであり、いずれも透明ではあるが、金属的な煌めきをもった装飾を施すことはできない。また網入・線入板ガラスは、ガラス中に金属線を含有するものであり、この金属線は、板ガラスの破損時の安全性を高めるという効果はあるものの、金属光沢はなく、装飾性に優れたものではない。
【0007】
また特許文献1の建築材料は、光を適当な状態で透過させることにより視覚的な美観を奏させるものであるが、樹脂は、紫外線、熱、水分等によって劣化し、変色やひび割れを発生しやすいため、長期間に亘って高い透光性を維持することが困難である。また特許文献1には、裏面側に金箔を貼り付けることも記載されているが、この場合には、透光性が失われると共に、金箔の一部が剥がれやすく、却って美観が損なわれる虞れがある。
【0008】
また特許文献2の建築材料は、内部に多数の気孔を有し、平均透過率が15〜85%であるため、ガラスの質感に富んだ外観を呈するが、金属光沢は得られない。
【0009】
本発明は、上記事情に鑑みなされたものであり、その目的とするところは、透明感を有し、しかも金属的な煌めきを持ち、装飾性に優れた建築用ガラス物品と、その製造方法を提供することである。
【0010】
【課題を解決するための手段】
本発明の建築用ガラス物品は、金及び/又は白金族元素を主成分とする金属片を含有することを特徴とする。
【0011】
また本発明の建築用ガラス物品の製造方法は、金及び/又は白金族元素を主成分とする金属片と、複数個のガラス小体を準備し、これらを耐火性容器内に充填した後、熱処理することによって、各ガラス小体を融着一体化させることを特徴とする。
【0012】
【発明の実施の形態】
本発明の建築用ガラス物品は、金及び/又は白金族元素を主成分とする金属片を含有するため、金属的な煌めきを持ち、装飾性に優れている。つまり、金を主成分とする金属片をガラス内部に含有すると、金色の光が金属片から放射されることになるため、金属的な煌めきを持ち、しかも立体感を有し、装飾性に優れたガラス物品が得られる。また白金族元素を主成分とする金属片をガラス内部に含有すると、銀色の光が金属片から放射されることになるため、全体的に金属的な煌めきを持ち、しかも立体感を有し、装飾性に優れたガラス物品が得られる。
【0013】
また本発明における金属片は、金や白金族元素を主成分とするため、熱的、化学的に非常に安定であり、高温下でも変質することがない。よって金属片が、ガラス物品の外表面に埋入され、その一部が空気中に露出していても、長期間に亘って酸化することはなく、光沢を維持することができる。尚、金を主成分とする金属片としては、金の含有量が37質量%以上のものが適しており、白金族元素を主成分とする金属片としては、白金やパラジウムからなるものが適している。
【0014】
また金属片は厚みが大きくなりすぎると、ガラスとの膨張差でクラックが生じる虞れがあるため、その厚みは2mm以下(好ましくは1mm以下、より好ましくは0.5mm以下が適当である。
【0015】
さらに本発明で使用するガラスは、波長400〜700nmの範囲における平均透過率(肉厚7mm)で、50%以上(好ましくは60%以上、より好ましくは70%以上)であると、高い透明感が得られ、金属片による金属的な煌めきの効果が発揮されやすいため好ましい。
【0016】
また本発明のガラス物品は、102〜1012個/kgの気孔を有すると、外部からガラス物品の表面に入射した可視光が気孔で反射したり、散乱し、全く気孔の存在しないガラス物品とは異なる趣を醸し出すことができる。
【0017】
さらに本発明のガラス物品は、透明感を維持し、金属片による金属的な煌めきが損なわれない範囲で、着色させることも可能である。ガラス物品を着色させる方法としては、ガラス中に着色成分を添加したり、無機顔料を混合する方法がある。着色成分としては、MnO2、Fe23、CoO、Cr23、NiO、CuO、V25等が適当である。また無機顔料としては、NiO、MnO2、CoO、Fe23、Cr23等の単体の着色酸化物、或いはZn−Cr−Ni−Alスピネル、Sn−Si−Ca−Cr−Znスフェイン、Zr−Sr−Prジルコン、Zr−Si−V−Prジルコン、Zr−Si−Vジルコン、Al−Co−Cr−Znスピネル、Al−Zn−Fe−Crスピネル、Fe−Cr−Zn−Alスピネル、Fe−Cr−Znスピネル、Fe−Cr−Ni−Mnスピネル等の多成分系の着色酸化物が適当であり、これらを混合して使用しても良い。
【0018】
また本発明の建築用ガラス物品は、各種の方法によって製造することができるが、特に集積法によって製造すると、金属片と気孔をガラス内部に均等に分散させやすいため好ましい。
【0019】
以下、本発明の建築用ガラス物品を集積法により製造する方法について説明する。
【0020】
まずNa2O−CaO系ガラスからなる成形体を粉砕したり、溶融ガラスを水中に投入し、水砕することによってガラス小体を作製する。ガラス小体は、特に形状は限定されず、例えば粒状、小片状、薄片状のものが使用できる。さらに金や白金族元素を主成分とする金属片(例えば金箔や白金箔)を複数枚準備する。
【0021】
次に、耐火性容器を準備し、この容器内部を離型剤で覆う。耐火性容器は、1100℃以下の温度で軟化変形しない材質のものを使用すべきであり、ムライト、コージエライト、アルミナセラミック等が適している。また離型剤としては、珪砂、アルミナ粉末、ジルコニア粉末、石膏粉末等の耐火性セラミック粉末を使用し、これをエアースプレー法、ハケ塗り法、或いは浸漬法によって容器内部に塗布しても良いが、セラミックファイバーシートを使用すると、容器内部に配置するだけで良いため作業性を軽減することができる。特に主成分がアルミナ、シリカ、シリカ−アルミナ又はジルコニアを含むセラミックファイバーシートは離型性に優れ、しかも熱処理後に離型剤を除去しやすいため好ましい。
【0022】
その後、上記ガラス小体の多数個を耐火性容器内に充填する。この際、複数枚の金属片をガラス小体に分散させる。これを所定の条件で熱処理すると、各ガラス小体が軟化変形し、融着一体化し、ガラス内部や外表面に金属片を含有するガラス物品が形成される。尚、この熱処理温度は、ガラス小体同志の融着が起こり、十分な機械的強度が得られるが、金属片の材料の融点より低い温度に設定される。つまり本発明で使用するガラスは、使用する金属片の融点より低い温度で軟化変形することが要求される。例えば、金を主成分とする金属片は、比較的融点が低いため、Na2O−CaO系ガラスが適している。また白金族元素を主成分とする金属片は、非常に融点が高いため、B23−SiO2系ガラス、Al23−SiO2系ガラス、あるいはB23−Al23−SiO2系ガラスが使用できる。
【0023】
【実施例】
以下、本発明を実施例に基づいて詳細に説明する。

【0027】
その後、これを950℃で100分間熱処理すると、各ガラス小体が軟化変形し、互いに融着一体化すると共に、一部のガラス小体の間隙が残存して気孔が形成された。これによってガラス内部と外表面に多数の金属片11と気孔12を含有する建築用ガラス物品10が得られた。この建築用ガラス物品10に光線を照射したところ、金色の光沢を持つ金属片11が煌めき、装飾性に優れていた。

【0029】
【発明の効果】
以上のように本発明の建築用ガラス物品は、金及び/又は白金族元素を主成分とする金属片を含有するため、金属的な煌めきを持ち、装飾性に優れているため、ホテル等のロビーに設置されるパーティションとして好適であり、その以外にも、ガラスブロック、窓材、化粧板、ガラスブリック等の建築材料として好適である。
【0030】
また本発明の製造方法によると、ガラス全体に均等に金属片を分散することができ、金属的な煌めきを持つ建築用ガラス物品を容易に得ることが可能である。

[Industrial applications]
The present invention relates to an architectural glass article having a metallic glitter and excellent decorativeness, and a method for producing the same.
[0002]
[Prior art]
With the diversification of the shapes and decorations of buildings, glass articles having decorative properties are increasingly used in some buildings from the viewpoint of design.
[0003]
As this type of architectural glass article, a template glass, a colored glass, a fashion glass baked with a special paint, a netted / wired plate glass, and the like are commercially available. Recently, a building material in which a large number of stone materials are mixed in a translucent resin (for example, Patent Document 1) and a building material having a large number of pores in glass (for example, Patent Document 2) have been proposed.
[0004]
[Patent Document 1]
JP-A-5-279509 [Patent Document 2]
JP-A-2001-180953
[Problems to be solved by the invention]
By the way, in recent years, it is desired that a partition installed in a lobby of a hotel has a sense of high quality as much as possible. For example, a partition having transparency and a metallic luster is required.
[0006]
However, architectural glass articles having conventional decorative properties do not satisfy the requirements. In other words, template glass is decorated by forming an uneven shape on the surface, colored glass is decorated by coloring, fashion glass is decorated by shape and coloring, all of which are transparent, but have a metallic sparkle Decorated decorations cannot be applied. In addition, net-in and wire-in sheet glass contains metal wire in the glass, and although this metal wire has the effect of increasing the safety in the event of breakage of the sheet glass, it has no metallic luster and is excellent in decorativeness Not something.
[0007]
Further, the building material disclosed in Patent Literature 1 provides visual aesthetics by transmitting light in an appropriate state. However, resin deteriorates due to ultraviolet light, heat, moisture, and the like, causing discoloration and cracking. Therefore, it is difficult to maintain high translucency over a long period of time. Patent Literature 1 also describes that a gold foil is stuck on the back surface side. In this case, however, the translucency is lost and a part of the gold foil is easily peeled off, which may impair the appearance. There is.
[0008]
Further, the building material of Patent Document 2 has a large number of pores inside and an average transmittance of 15 to 85%, and thus has an appearance rich in glass texture, but does not have metallic luster.
[0009]
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an architectural glass article which has a transparent feeling, has a metallic glitter, and is excellent in decorativeness, and a method for producing the same. To provide.
[0010]
[Means for Solving the Problems]
The architectural glass article of the present invention is characterized by containing a metal piece mainly containing gold and / or a platinum group element.
[0011]
Further, the method for producing a building glass article of the present invention comprises preparing a metal piece mainly composed of gold and / or a platinum group element and a plurality of glass bodies, filling these in a fire-resistant container, It is characterized in that each glass body is fused and integrated by heat treatment.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Since the architectural glass article of the present invention contains a metal piece containing gold and / or a platinum group element as a main component, it has a metallic glitter and is excellent in decorativeness. In other words, when a metal piece containing gold as a main component is contained in the glass, gold light is emitted from the metal piece, so it has a metallic sparkle, has a three-dimensional effect, and is excellent in decorativeness. The resulting glass article is obtained. In addition, when a metal piece containing a platinum group element as a main component is contained in the glass, silver light is radiated from the metal piece, so that it has a metallic glitter as a whole and has a three-dimensional appearance, A glass article excellent in decorativeness is obtained.
[0013]
Further, since the metal piece in the present invention contains gold or a platinum group element as a main component, it is very thermally and chemically stable, and does not deteriorate even at a high temperature. Therefore, even if the metal piece is embedded in the outer surface of the glass article and a part of the metal piece is exposed to the air, the metal piece does not oxidize for a long period of time and can maintain the gloss. A metal piece containing gold as a main component is preferably a metal piece containing 37% by mass or more of gold, and a metal piece containing a platinum group element as a main component is preferably made of platinum or palladium. ing.
[0014]
If the thickness of the metal piece is too large, cracks may occur due to the difference in expansion from the glass. Therefore, the thickness is suitably 2 mm or less (preferably 1 mm or less, more preferably 0.5 mm or less).
[0015]
Further, when the glass used in the present invention has an average transmittance (wall thickness of 7 mm) in the wavelength range of 400 to 700 nm of 50% or more (preferably 60% or more, more preferably 70% or more), high transparency is obtained. Is obtained, and the effect of metallic sparkle by the metal piece is easily exerted.
[0016]
Further, when the glass article of the present invention has pores of 10 2 to 10 12 cells / kg, visible light incident on the surface of the glass article from the outside is reflected or scattered by the pores, and the glass article has no pores. You can create a different taste from the one.
[0017]
Further, the glass article of the present invention can be colored as long as the transparency is maintained and the metallic sparkle of the metal pieces is not impaired. As a method of coloring a glass article, there is a method of adding a coloring component to glass or mixing an inorganic pigment. Suitable coloring components include MnO 2 , Fe 2 O 3 , CoO, Cr 2 O 3 , NiO, CuO, V 2 O 5 and the like. As the inorganic pigment, a single colored oxide such as NiO, MnO 2 , CoO, Fe 2 O 3 , Cr 2 O 3 , or Zn—Cr—Ni—Al spinel, or Sn—Si—Ca—Cr—Zn spherine , Zr-Sr-Pr zircon, Zr-Si-V-Pr zircon, Zr-Si-V zircon, Al-Co-Cr-Zn spinel, Al-Zn-Fe-Cr spinel, Fe-Cr-Zn-Al spinel , Fe-Cr-Zn spinel, Fe-Cr-Ni-Mn spinel, etc. are suitable, and these may be used as a mixture.
[0018]
Further, the architectural glass article of the present invention can be manufactured by various methods, but it is particularly preferable to manufacture the glass article by an integration method because the metal pieces and pores are easily dispersed uniformly in the glass.
[0019]
Hereinafter, a method of manufacturing the architectural glass article of the present invention by an integration method will be described.
[0020]
First, a molded body made of a Na 2 O—CaO-based glass is crushed, or a molten glass is put into water and crushed with water to produce a glass body. The shape of the glass body is not particularly limited, and for example, a glass body, a small piece, or a thin piece can be used. Further, a plurality of metal pieces (for example, gold foil or platinum foil) mainly containing gold or a platinum group element are prepared.
[0021]
Next, a refractory container is prepared, and the inside of the container is covered with a release agent. The refractory container should be made of a material that does not soften and deform at a temperature of 1100 ° C. or less, and mullite, cordierite, alumina ceramic, and the like are suitable. As the release agent, silica sand, alumina powder, zirconia powder, refractory ceramic powder such as gypsum powder is used, and this may be applied to the inside of the container by an air spray method, a brush coating method, or an immersion method. When a ceramic fiber sheet is used, the workability can be reduced because it is only necessary to arrange the inside of the container. In particular, a ceramic fiber sheet whose main component contains alumina, silica, silica-alumina or zirconia is preferable because of excellent releasability and easy removal of the release agent after heat treatment.
[0022]
Thereafter, a large number of the glass bodies are filled in a refractory container. At this time, a plurality of metal pieces are dispersed in the glass body. When this is heat-treated under predetermined conditions, each glass body softens and deforms, and is fused and integrated to form a glass article containing a metal piece on the inside or outside surface of the glass. The heat treatment temperature is set to a temperature lower than the melting point of the material of the metal piece, although fusion of the glass bodies occurs and sufficient mechanical strength is obtained. That is, the glass used in the present invention is required to be softened and deformed at a temperature lower than the melting point of the metal piece used. For example, a metal piece containing gold as a main component has a relatively low melting point, so that a Na 2 O—CaO-based glass is suitable. Further, since a metal piece containing a platinum group element as a main component has a very high melting point, B 2 O 3 —SiO 2 glass, Al 2 O 3 —SiO 2 glass, or B 2 O 3 —Al 2 O 3 -SiO 2 based glass can be used.
[0023]
【Example】

The average transmittance (with a thickness of 7 mm) in the range of 87700 nm was 87%. In addition, several tens of platinum foils having a thickness of 80 μm and a size of about 5 mm square were dispersed in the glass body.
[0028]
Thereafter, when this was heat-treated at 1100 ° C. for 100 minutes, each glass body softened and deformed, fused and integrated with each other, and a gap was left between some glass bodies to form pores. As a result, an architectural glass article 10 containing a large number of metal pieces 11 and pores 12 inside and outside the glass was obtained. When this architectural glass article 10 was irradiated with a light beam, the metal piece 11 having a silvery luster shone and was excellent in decorativeness.
[0029]
【The invention's effect】
As described above, the architectural glass article of the present invention contains a metal piece containing gold and / or a platinum group element as a main component, has a metallic sparkle, and is excellent in decorativeness. It is suitable as a partition installed in a lobby, and in addition, it is also suitable as a building material such as a glass block, a window material, a decorative board, and a glass brick.
[0030]
Further, according to the production method of the present invention, metal pieces can be evenly dispersed throughout the glass, and an architectural glass article having a metallic glitter can be easily obtained.
