Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a laminated glass having a thin piece of metal or a thin plate such as a perforated metal sheet, which is useful as an exterior material in buildings and the like. The present invention relates to a colored laminated glass that is colored and decorated.

[Prior Art and its Problems] For example, as disclosed in Japanese Patent Laid-Open No. 63-5939, metal powder, foil pieces, and the like are scattered between a pair of glass plates, and the glass plates are bonded and integrated through a resin film. It is well known that it is transformed.

In No. 61-62026, there is a laminated glass for electromagnetic shielding in which punching metal is sandwiched between glass plates, and in No. 1-119789, there is a metal plate with through holes between the glass plates. A laminated glass for crime prevention fixed with a frame or sandwiched without a surrounding frame, a laminated glass with a metal plate and a foil interposed therebetween as disclosed in a double-layered glass is known.

However, Japanese Utility Model Laid-Open No. 61-62026 is intended for electromagnetic shielding, and in order to obtain the electromagnetic shielding effect, the hole size and the hole interval (pitch) should be as narrow as possible and the holes should be regularly arranged. It must be said that it is not an appropriate pattern in itself for obtaining a decorative effect.

What can be said in common with the above disclosed examples is that, in these disclosed examples, a plurality of opaque thin plates or a plurality of opaque thin plates having a plurality of pattern holes formed between a pair of glass plates are transparently bonded to each other as in the present invention. When sandwiching through the film,
The pair of adhesive films have different color tones,
In addition, it has not been disclosed or suggested that the portion in which both adhesive films are in direct contact has yet another color tone consisting of those intermediate colors and thereby obtains multicolor chromaticity.

The present invention arranges a thin piece of resin, metal or the like, or a perforated thin plate between a pair of adhesive films having different color tones, so that the parts in contact with these thin plates and thin plates have different front and back color tones, and the parts where the adhesive film directly contacts. Is a multi-colored color that can be seen through and has another color tone consisting of the intermediate color of both adhesive films,
It is intended to provide a laminated glass with a high degree of decorativeness.

[Means for solving problems]

The present invention relates to a colored laminated glass, in which a plurality of opaque flakes having a graphic pattern contour are sandwiched between a pair of transparent glass plates via a pair of transparent adhesive films, and the pair of adhesive films are provided. Differed in color tone from each other, and the part where both adhesive films were in direct contact with each other exhibited a different color tone consisting of their intermediate color,
Alternatively, in a laminated glass in which a pair of transparent glass plates are sandwiched by an opaque thin plate having a large number of graphic patterns formed through a pair of transparent adhesive films, the pair of adhesive films have different color tones, and both adhesive films The part which is directly contacted with has a further color tone of the intermediate color thereof, and preferably, the thin piece or the thin plate is made of metal.

The transparent glass plate, the opaque flakes, the thin plate and the like may be colored or colorless and may be those that are well balanced with the color tone of the adhesive film.

The glass plate may be made of various materials such as soda lime glass, and may also include those having semi-transparency such as template glass, and may be tempered or bent plate glass.

The thin piece and the thin plate may be made of any material, but it is preferable that they give functionality such as heat resistance, heat insulation, and robustness in addition to the decorative property. Especially, if the metal is a metal, the metal surface reflects heat rays and is heat insulating. In addition, it has heat resistance itself, and in the case of a metal thin plate, preferably a SUS plate, it has the function of preventing the glass from scattering and peeling even if it is subjected to external thermal or mechanical shock. It is convenient to have. In addition, as the thin metal plate, various types such as those having a glossy surface, those having a matte surface, those having a satin pattern, and those having been plated can be adopted, whereby the color feeling can be changed.

The thickness of these thin pieces and thin plates is not particularly limited, but if it exceeds 1 mm, the level difference between the interposed portion and the non-inserted portion is too large, and bubbles are generated between the adhesive films, and the decorative property is easily impaired. Also, when a thin plate is used, if it is less than 0.2 mm, workability during manufacturing deteriorates and wrinkles may occur during handling. In the case of a metal thin plate that imparts heat resistance and robustness,
If it is less than 0.2 mm, its action and effect will be insufficient. Generally, if the range is 0.2 to 1 mm, no inconvenience will occur.

The contour pattern of the thin piece and the perforation pattern of the thin plate do not limit the shape, and may be not only a geometric shape formed by a circle, an ellipse, a polygon or the like, or an abstract shape.

The size of these patterns is not limited, but if the contour pattern of a thin piece is, for example, a circle, its color spot effect is visually weakened when its diameter is less than 3 mm, and its decorativeness is poor. The partial area in which is blocked is too wide and the field of view is easily obstructed. Therefore, the length is set to 3 to 100 mm, preferably about 8 to 50 mm, and other shape patterns are also considered and set according to this.

For example, if the perforation pattern of a thin plate is a circle, its diameter is 3 m.
If it is less than m, the visibility is obstructed because the partial area where the transparency is obstructed is too wide, and the decorativeness is apt to be impaired.
If it exceeds m, the hiding property will be impaired, and heat resistance and heat insulation will be insufficient. Therefore, 3 to 100 mm, preferably 8 to 50 mm
The degree is set, and other shape patterns are also considered and set according to this.

The ratio of the see-through area to the entire glass plate is preferably about 20% to 70% in consideration of appropriate see-through property, concealing property, colorful color due to pattern, and decorative property.

The transparent adhesive film may be made of polyvinyl butyral, ethylene vinyl acetate or the like which is usually recommended as an interlayer film for laminated glass, and various colored films of these are commercially available.

The thickness of each of the pair of adhesive films is appropriately set in consideration of the thickness of the thin piece and the thin plate and the size of the graphic pattern, and the thickness in the range of about 0.3 mm to 2.4 mm is used. Of course, a thick adhesive film can be obtained by laminating thin adhesive films, and it is possible to obtain an intermediate color tone or change the shade of color by combining the color tone of colorless films.

With the transparent adhesive film, the light transmittance of the colored laminated glass can be freely set within the range of 10 to 80%, and accordingly, the transparency and the concealing property can be adjusted, and in addition to blocking harmful ultraviolet rays,
It has an effect of facilitating optical and thermal preparation such as blocking of infrared rays or far infrared rays.

In addition, when adopting a corrosive material for the thin piece and the thin plate,
If this is exposed to the end surface of the glass plate, it is likely to damage the aesthetics due to corrosion from that part and progressing to the inside, so it is convenient to place it slightly inside the peripheral edge of the glass plate and seal it with the adhesive film. Is good.
