Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative laminated glass sheet having a pattern and see-through property.

[0002]

2. Description of the Related Art In recent years, with the progress of society and the rapid rise in the level of living, a wall member, a panel member such as a door or a window having a good lighting property and a decorative property is used for a high-rise building or a residential building. In addition, the demand for transparency and decorativeness of desan, which is rich in variability and nuance, has come to be demanded for room partition members and furniture panel members.

In order to meet such demands, conventionally, a sheet of glass plate is directly printed with a desired color pattern or pattern, or a resin film having a color pattern printed thereon is attached with an adhesive, or a resin film. It was the one obtained by transferring the color pattern printed on the plate glass surface. However, such a piece of glass composed of a color pattern or a patterned coating or coating layer on the surface of the glass is vulnerable to sunlight and comes into contact with air, so the color may fade or dust may adhere to it and wipe it off. It was scratched and could not be used for a long time and could only be used as an interior item.

Further, a decorative laminated glass in which a film having a color pattern is interposed between two pieces of glass and bonded with an adhesive has been proposed, but a film having a color pattern used for the laminated glass is manufactured. It is not easy to do this, and when laminating the two glass sheets and pasting them together, a pressure and heating process is generally required.Therefore, bubbles and color pattern collapse on the film bonding surface with the color pattern. To prevent this, high technology and expensive equipment are used, so the manufacturing cost is high, and further, this laminated glass for decoration deteriorates adhesion due to changes in temperature and humidity of the surrounding environment, and the two glasses are stuck to each other. If peeling occurs, or if the edge is not completely sealed, moisture may penetrate from the edge to the joint surface, resulting in air bubbles or fogging on the peripheral edge. It was.

In addition, the decorative laminated glass obtained by laminating the above-mentioned one piece of decorative glass and two pieces of glass often uses an opaque and general colored paint for the production of pattern designs, etc. In the past, such decorative laminated glass has hitherto been used for interior partitioning members, door panels or wall decorative panels, because the color may fade or the coating layer may fall off when exposed to the atmosphere or sunlight for a long time. It is often used as a window, but it could not be used as a window for a building, a surrounding wall panel member, or a glass for a curtain wall.

[0006]

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a decorative laminated glass sheet with a pattern that can be used both indoors and outdoors, and more specifically, a room partition.

DISCLOSURE OF THE INVENTION The present invention is a decoration which is conventionally formed by laminating two sheets of glass with an adhesive through a resin film on which a color pattern or a pattern pattern figure is printed. This is an improved laminated glass, that is, the present invention provides a predetermined pattern with an opaque colored paint on one surface of the first plate glass between a first plate glass made of transparent plate glass and a second plate glass. A first coating layer including an opaque portion formed by applying a desired pattern or figure and a space portion not coated with a coating material, and the predetermined pattern on the opaque portion of the first coating layer. Second and third coating layers, each of which includes a coating portion formed by applying white and black or gray coating material having the same pattern as the above and a space portion corresponding to the space portion and not coated with the coating material, Of the first coating layer To provide a The inter and the second and third transparent become stuck with adhesive decorative laminate glass plate for simultaneously filling the space in the.

The predetermined pattern is composed of a plurality of dots, a plurality of hexagonal patterns, or a vertical and horizontal pattern or a net-like pattern, which is printed by a known screen printing method.

The colored paint, white and black or gray paint is a mixture of ceramic frit and glass frit powder with good heat resistance, and the colored paint has CaO, MnO, CdS, Cr ₂ O ₃ , or as a pigment. Fc ₂ O ₃ or the like is used. The preferred contents are 30 wt% or less for ceramic frit and 30 to 70 wt% for glass frit powder.
Those in the range of are used. Further, for the coating material, one of polyvinyl butyral resin, urethane resin, epoxy resin, methyl acrylate resin, etc., or a mixture thereof is used by mixing an appropriate amount of the above-mentioned pigment, and the coating layer has a thickness of 0.04 to It is formed with 0.18 mm.

[0014]

When the laminated glass sheet for decoration of the present invention having the above-mentioned structure is used as a glass for a panel of a wall of a building, a window or a curtain wall, the first coating layer is attached to the outdoor side. . Then, the pattern or figure of the colored color pattern formed as the opaque portion of the first coating layer can be seen from the outside, but the difference in brightness between the inside and the outside can be seen from the space where the paint is not applied. Therefore, the inside of the room cannot be easily seen. On the contrary, when viewed from the inside of the room to the outside, the outside view can be seen through the space portion of the coating layer due to the difference in brightness between the inside and the outside.

Alternatively, the ratio of the area between the opaque portion and the space portion of the coating layer can be adjusted arbitrarily, preferably 9: 1 to 6.5: 3.5, more preferably 5: 5. Can be That is, when it is desired to let more light rays from the outside enter the room, the area of the opaque coating portion may be reduced, and in the opposite case, the area of the opaque coating portion may be increased. The colored color pattern of the first paint coating layer can be a desired pattern or figure according to the design of the building.

The adhesive layer is a transparent adhesive, such as a polyvinyl butyral resin adhesive, a polyester resin adhesive, a methyl acrylate (acrylic) resin adhesive, a two-component epoxy resin adhesive, a urethane resin adhesive, or It is selected from single-component thermosetting adhesives and the like. Then, on the adhesive layer surface, an opaque second white and a third opaque paint formed
Since there is a black or gray paint pattern coating layer of
Never double shadow visual on the glass surface also room facing to the thickness of the adhesive is increased to 50 mm (ghost images) occurs, when the thickness of the adhesive layer 0.01 mm, The strength is improved by 30% or more as compared with one sheet of glass having the same thickness. If the thickness of the laminated glass is increased to 50 mm, the puncture resistance becomes 100%, and when broken, the fragments do not scatter like ordinary laminated glass. Furthermore, if an infrared absorbing agent or an ultraviolet absorbing agent is mixed with the adhesive, it has a heat insulating effect, and the strength can be further improved by stretching a reinforcing steel wire or copper wire on the adhesive layer. The colored color pattern coating layer is made of a ceramic frit and does not fade even when exposed to the air and is not scratched. And if the thickness of the adhesive layer is appropriate, a sufficient soundproofing effect can be expected.
