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、金を主成分とする球状金属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、金を主成分とする金属箔と、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と共に、金属箔を球状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、金を主成分とする球状金属を含有するため、金属的な煌めきを持ち、装飾性に優れている。つまり、金を主成分とする球状金属をガラス内部に含有すると、金色の光が全方向に均等に放射されることになるため、ガラス全面が均一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球状金属は、金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。よって球状金属が、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、金を主成分とする球状金属としては、金の含有量が37質量%以上であり、アスペクト比(縦横比)が2以下の球状金属が適している。
【0014】
さらに球状金属は、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、その最大径は5mm以下(好ましくは3mm以下、より好ましくは2mm以下)とするのが適当である。また球状金属が小さすぎると、ガラス物品に金属的な煌めきを与える効果が乏しくなるため、その最大径は0.1mm以上(好ましくは0.3mm以上、より好ましくは0.5mm以上)とするのが適当である。
【0015】
また本発明で使用するガラスは、30〜380℃における平均熱膨張係数が70×10-7/℃以下であると、熱処理工程における冷却時の熱衝撃や、激しい気温の変化による熱衝撃でも破損することがないため好ましい。
【0016】
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、球状金属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。
【0017】
具体的には、B23−SiO2系ガラス、Al23−SiO2系ガラス、あるいはB23−Al23−SiO2系ガラスを使用すると、上記の熱膨張係数や平均透過率が得られやすく、また耐候性に優れているため好ましい。
【0018】
特に質量%で、SiO2 55〜68%、Al23 10〜25%、B23 3〜15%、MgO 0〜10%、CaO 0〜10%、SrO 0〜10%、BaO 0〜10%、ZnO 0〜5%の組成を有するガラスは、平均熱膨張係数が40×10-7/℃以下であり、非常に優れた耐候性を有するため好適である。
【0019】
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。
【0020】
さらに本発明のガラス物品は、透明感を維持し、球状金属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。
【0021】
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、ガラス小体を融着させるための熱処理によって金属箔が球状となりやすく、しかも球状金属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。
【0022】
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。
【0023】
まずガラス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。さらに金を主成分とする金属箔(例えば金箔)を複数枚準備する。この金属箔は、厚みが10〜500μmのものが適当である。
【0024】
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。
【0025】
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、複数枚の金箔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、融着一体化すると同時に、金属箔が軟化変形し、表面張力で球状となり、ガラス内部や外表面に球状金属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と共に、金属箔の材料の融点より高い温度となるように設定される。
【0026】
【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】
図1は、本発明の建築用ガラス物品10を示す斜視図である。この建築用ガラス物品10は、900×1200×18mmの大きさを有し、その内部及び外表面には、多数個の球状金属11と気孔12を含有している。球状金属11は、主成分が金であり、その最大径は1.5mmである。また気孔12の数は、目視観察によって約107個/kgである。
【0028】
この建築用ガラス物品10は、質量%で、SiO2 60%、Al23 15%、B23 10%、CaO 5%、SrO 6%、BaO 2%、ZnO 0.5%、ZrO2 0.5%、Sb23 1%からなり、30〜380℃における平均熱膨張係数が37×10-7/℃、波長400〜700nmの範囲における平均透過率(肉厚7mm)が80%のガラスから作製されている。
【0029】
この建築用ガラス物品10は、以下のようにして作製した。
【0030】
まず離型剤としてアルミナセラミックファイバーシートを底面と側面に配置したアルミナセラミック製の耐火性容器の内部に、平均粒径が3mmのガラス小体を充填した。またガラス小体の中には、厚さ200μmで約3mm角の金箔を数十枚分散させた。
【0031】
その後、これを1100℃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る。また同時に金箔も軟化変形して球状となり、これによってガラス内部と外表面に多数の球状金属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、金色の光沢を持つ球状金属が煌めき、装飾性に優れていた。
【0032】
【発明の効果】
以上のように本発明の建築用ガラス物品は、金を主成分とする球状金属を含有するため、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。
【0033】
また本発明の製造方法によると、ガラス全体に均等に球状金属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 spherical metal mainly composed of gold.
[0011]
In addition, the method for producing a building glass article of the present invention comprises preparing a metal foil containing gold as a main component and a plurality of glass bodies, filling them in a refractory container, and then performing heat treatment. It is characterized in that the glass body is fused and integrated and the metal foil is made spherical.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Since the architectural glass article of the present invention contains a spherical metal mainly composed of gold, it has a metallic glitter and is excellent in decorativeness. In other words, if a spherical metal mainly composed of gold is contained inside the glass, the gold light will be emitted uniformly in all directions, so that the entire surface of the glass has a uniform metallic sparkle and has a three-dimensional appearance. Thus, a glass article having excellent decorativeness can be obtained.
[0013]
Further, since the spherical metal in the present invention is mainly composed of gold, it is extremely stable thermally and chemically and does not deteriorate even at high temperatures. Therefore, even if the spherical metal is embedded in the outer surface of the glass article and a part thereof is exposed to the air, it does not oxidize for a long period of time and can maintain the luster. As the spherical metal mainly composed of gold, a spherical metal having a gold content of 37% by mass or more and an aspect ratio (aspect ratio) of 2 or less is suitable.
[0014]
Further, if the spherical metal is too large, cracks may occur due to the difference in expansion from the glass, so that the maximum diameter is suitably 5 mm or less (preferably 3 mm or less, more preferably 2 mm or less). . Also, if the spherical metal is too small, the effect of giving metallic sparkle to the glass article becomes poor, so the maximum diameter is set to 0.1 mm or more (preferably 0.3 mm or more, more preferably 0.5 mm or more). Is appropriate.
[0015]
When the glass used in the present invention has an average coefficient of thermal expansion at 30 to 380 ° C. of 70 × 10 −7 / ° C. or less, the glass is damaged by thermal shock during cooling in a heat treatment step or thermal shock due to a severe change in air temperature. This is preferable because it does not occur.
[0016]
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 metallic sparkle effect of the spherical metal is easily exerted.
[0017]
Specifically, when a B 2 O 3 —SiO 2 glass, an Al 2 O 3 —SiO 2 glass, or a B 2 O 3 —Al 2 O 3 —SiO 2 glass is used, It is preferable because the average transmittance is easily obtained and the weather resistance is excellent.
[0018]
Especially in mass%, SiO 2 55~68%, Al 2 O 3 10~25%, B 2 O 3 3~15%, 0~10% MgO, CaO 0~10%, SrO 0~10%, BaO 0 Glass having a composition of 10% to 10% and ZnO of 0% to 5% is preferable because it has an average coefficient of thermal expansion of 40 × 10 −7 / ° C. or less and has extremely excellent weather resistance.
[0019]
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.
[0020]
Furthermore, the glass article of the present invention can be colored as long as it maintains a sense of transparency and does not impair the metallic sparkle of the spherical metal. 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.
[0021]
The architectural glass article of the present invention can be manufactured by various methods.In particular, when manufactured by an integration method, the metal foil tends to be spherical by heat treatment for fusing the glass body, and moreover, the spherical metal and This is preferable because the pores are easily dispersed evenly inside the glass.
[0022]
Hereinafter, a method of manufacturing the architectural glass article of the present invention by an integration method will be described.
[0023]
First, a glass molded body is crushed, or molten glass is put into water, and then water crushed 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 foils (for example, gold foil) mainly containing gold are prepared. This metal foil having a thickness of 10 to 500 μm is suitable.
[0024]
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.
[0025]
Thereafter, a large number of the glass bodies are filled in a refractory container. At this time, a plurality of gold foils are dispersed in the glass body. When this is heat-treated under predetermined conditions, each glass body softens and deforms and fuses and integrates, and at the same time, the metal foil softens and deforms, and becomes spherical due to surface tension. An article is formed. The heat treatment temperature is set so that the glass bodies are fused together, sufficient mechanical strength is obtained, and the temperature is higher than the melting point of the material of the metal foil.
[0026]

[0029]
This architectural glass article 10 was produced as follows.
[0030]
First, a glass body having an average particle diameter of 3 mm was filled in an alumina ceramic refractory container in which an alumina ceramic fiber sheet as a release agent was disposed on the bottom and side surfaces. In addition, several tens of about 3 mm square gold foils having a thickness of 200 μm were dispersed in the glass body.
[0031]
Thereafter, when this is heat-treated at 1100 ° C. for 100 minutes, each glass body softens and deforms, and is fused and integrated with each other, and pores are formed by leaving a gap between some glass bodies. At the same time, the gold foil was also softened and deformed into a spherical shape, whereby an architectural glass article 10 containing a large number of spherical metals 11 and pores 12 inside and outside the glass was obtained. When this architectural glass article 10 was irradiated with a light beam, the spherical metal having a golden luster glowed and was excellent in decorativeness.
[0032]
【The invention's effect】
As described above, the architectural glass article of the present invention contains a spherical metal containing gold as a main component, has a metallic sparkle, and has excellent decorative properties. In addition, it is suitable as a building material such as a glass block, a window material, a decorative board, and a glass brick.
[0033]
Further, according to the production method of the present invention, the spherical metal can be evenly dispersed throughout the glass, and an architectural glass article having a metallic glitter can be easily obtained.
