Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a decorative plate such as a decorative laminated glass comprising a laminate in which a decorative intermediate member is sandwiched between two opposing plate materials such as glass.
[0002]
[Prior art]
The tempered glass is bonded to two ordinary glass plates and sandwiched therebetween to form a three-layer laminated glass, and thereafter, a shock is applied to one edge of the middle tempered glass to cause a crack to obtain decorativeness. Decorative glass has been developed (for example, Patent Documents 1 and 2).
[0003]
Tempered glass is made by heating a normal glass plate to near the softening point and then quenching it to cause strain on the surface layer due to compressive stress and internal strain due to tensile stress. Is big. In such a tempered glass, once a crack is generated by applying an impact, the crack spreads over the entire surface of the glass plate due to the action of internal strain, and fine cracks are formed on the entire surface of the glass plate.
[0004]
3A and 3B show a conventional decorative glass, in which FIG. 3A is a front view, and FIG. 3B is a cross-sectional view of FIG. The cross-sectional view is a conceptual diagram exaggerating the scale.
As shown in the figure, the conventional decorative glass 55 is composed of a three-layer glass plate of a normal glass plate 51 on both sides and a middle tempered glass 52 as shown in FIG. An impact is applied to one location with a tool (only) to generate a crack 53. As shown in (A), the crack 53 is formed from a crushed portion 54 to which an impact is applied as a starting point, and fine cracks unique to tempered glass are formed on the entire surface of the glass plate.
[0005]
[Patent Document 1]
JP-B-47-1636 [Patent Document 2]
JP-A-57-156343
[Problems to be solved by the invention]
However, the decorative glass described in Patent Literature 1 and Patent Literature 2 in which a tempered glass is sandwiched in advance to form a crack has a pattern derived from a fine crack pattern peculiar to the tempered glass, and is a novel and highly decorative free. Pattern cannot be formed.
[0007]
Further, since the sandwiched tempered glass is adhered to the glass plates on both sides, the tempered glass is cracked while the surfaces of the tempered glass and the glass plates on both sides are stuck together. Therefore, as shown in FIG. 3B, the tempered glass 52 has cracks 53 almost perpendicular to the surfaces of the glass plates 51 on both sides. For this reason, when light strikes, the light is reflected in a substantially constant direction, and a pattern rich in glitter and change in glitter cannot be obtained.
[0008]
Furthermore, a new tempered glass sandwiched in between must be used, which is not preferable from the viewpoint of resource saving, productivity and environmental problems, and is disadvantageous in cost.
[0009]
On the other hand, in a decorative glass using two opposing glass plates, as an intermediate member sandwiched between the glass plates, a transparent PET film or sheet or the like with a pattern applied thereto, or an actual material such as flowers or leaves is used. It has been considered to use it to form decorative glass.
[0010]
However, even when such a film or an actual plant is interposed, the pattern itself is always constant, and the diversity due to the change in the overall glitter and the change in the position of the fine luminescent spot according to the angle of the light, etc. It is not possible to get a certain variety of patterns.
[0011]
The present invention has been made in consideration of the above-mentioned conventional technology, and can form a free pattern, has a glitter and a change in glitter according to the angle of light, and can be recycled without using a newly created tempered glass. An object of the present invention is to provide a decorative plate such as a laminated glass capable of saving resources and a method for manufacturing the same.
[0012]
[Means for Solving the Problems]
In order to achieve the object, according to the present invention, in a decorative plate in which an intermediate member is sandwiched between two opposing light-transmitting plate members with an adhesive therebetween, the intermediate member is solid particles dispersed in an arbitrary pattern. A decorative plate is provided.
[0013]
According to this configuration, since the solid particles can be freely arranged, the pattern can be freely expressed, and various patterns can be drawn. Therefore, the range of decorativeness is expanded, and the design is improved. Further, by scattering amorphous solid particles, the reflected light is changed according to the angle of the light, and the glitter and the luminescent spot are changed, so that a pattern rich in change is obtained according to the viewing angle. The plate is a translucent member such as transparent or translucent, and an ordinary glass plate or a plate made of resin can be used.
[0014]
In a preferred configuration example, the solid particles are fragments of a glass plate.
[0015]
According to this configuration, due to refraction or reflection of light by the particles of the glass shards, for example, when light is applied to the decorative plate, which is a laminated glass, glitter and a change in brilliancy occur, and the decorativeness is improved.
[0016]
In a preferred configuration example, the solid particles use recycled glass.
[0017]
According to this configuration, it is possible to manufacture a decorative plate by using pieces of tempered glass that have become unnecessary, such as pieces of unnecessary portions that are inevitably generated in the manufacture of tempered glass products, and tempered glass that is purposely sandwiched in the middle Since there is no need to manufacture, it is possible to improve productivity, save resources by recycling, contribute to environmental problems, and reduce costs.
[0018]
Further, in the present invention, the first adhesive film is placed on the first plate material, the solid particles are placed on the first adhesive film, and the second adhesive film is placed on the solid particles. Then, a second plate is placed on the second adhesive film, and the solid particles are welded and fixed between the first and second plate materials by heat treatment of the first and second adhesive films. A method for producing a decorative plate is provided.
[0019]
According to this configuration, for example, the solid particles can be freely arranged at room temperature on the thermoplastic adhesive film, so that the pattern can be freely expressed and various patterns can be drawn. Thereafter, the laminate composed of the adhesive film and the plate material sandwiching the solid particles is heat-treated to dissolve the adhesive film, and the fixed particles can be fixed by welding. As a result, a decorative plate having a wider decorative range and an improved design can be obtained.
[0020]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a laminated glass that is an embodiment of a decorative plate according to the present invention and a method for manufacturing the same will be described with reference to the drawings.
[0021]
1A and 1B show a laminated glass according to an embodiment of the present invention, wherein FIG. 1A is a front view, and FIG. 1B is a cross-sectional view taken along line AA of FIG.
The laminated glass 1 according to the present invention is formed by sandwiching a granular glass piece 3 between two glass plates 2 facing each other. As the glass plate 2, for example, a tempered glass having a thickness of 5 mm is used, but float glass may be used. The thickness of the glass plate 2 may be selected in consideration of the strength according to the area of the laminated glass 1. A sealing seal 4 such as a non-combustible material is attached to the outer peripheral edge of the laminated glass 1 as necessary. Thereby, since the glass piece 3 can be prevented from protruding from the outer periphery of the laminated glass 1, the handleability is improved.
[0022]
If a piece of glass that is inevitably generated at the stage of manufacturing the tempered glass is used as the glass piece 3, it is not necessary to manufacture the tempered glass when manufacturing the laminated glass according to the present invention. The glass piece 3 is obtained by finely crushing the shards and sizing the shards to form granules having almost the same size. The glass piece 3 is not limited to tempered glass, and may be a piece of ordinary glass plate that has been sized and granulated, or a piece of colored glass plate. As described above, if a piece of a glass plate to be discarded is used as the glass piece 3, a recycled product can be used, resources can be saved, environmental problems can be contributed, and costs can be reduced.
[0023]
FIG. 2 is a schematic view showing the manufacturing steps of the laminated glass according to the present invention shown in FIG. 1 in order.
As shown in (A), first, the first glass plate 2a is placed horizontally. The first adhesive film 5a is placed on this. The adhesive film 5a is made of a thermoplastic material. A glass piece 3 is laid thereon and laminated. For example, a reinforced glass of 2000 mm × 1000 mm and a thickness of 5 mm is used as the glass plate 2 a, and a dummylan (trade name, manufactured by Mitsui Takeda Chemical Co., Ltd.) having a thickness of 0.4 mm is used as the adhesive film 5 a in two layers.
[0024]
When the tempered glass is used for the glass piece 3, the fragments generated in the manufacturing stage are finely crushed, sized through a 4 to 5 mesh wire mesh, washed with water to remove dust and foreign matter, and dried to remove moisture. It has been removed. Similarly, when a normal plate glass is used as the glass piece 3, a piece obtained by pulverizing fine pieces generated in a manufacturing stage, washing the same with water to remove dust and foreign matters, and drying to remove moisture is used.
[0025]
The glass piece 3 is laid to a position slightly inside the outer peripheral edge of the glass plate 2a. At this time, a frame material (not shown) may be provided at the peripheral edge. Further, for example, a piece of paper or the like on which a sketch is drawn may be laid below the glass plate 2a, and the glass piece 3 may be laid in accordance with the sketch. Thereby, many patterns can be easily drawn based on the sketch. Further, the upper surface of the glass plate 2a may be divided by an appropriate partition member (not shown), and a color pattern or another pattern may be drawn for each section using glass pieces of various colored glasses.
[0026]
In the present embodiment, since the angle of the surface of the glass piece 3 having an irregular shape is spread all over the surface, irregular reflection occurs when the light hits, and it is determined by the angle of light depending on the viewing direction or the direction of natural light or illumination light. The brightness changes and the range of decorativeness expands. Further, since the opposite side can be made invisible, it can be used as a privacy glass.
[0027]
Next, as shown in (B), the second adhesive film 5b is mounted again on the spread glass pieces 3, and the second glass plate 2b is mounted thereon. The second adhesive film 5b and the second glass plate 2b may be the same as the first adhesive film 5a and the first glass plate 2a, respectively. Thereafter, the peripheral edge of the laminated glass is temporarily fixed with a tape or the like, and placed on a heating furnace table at a predetermined temperature according to the adhesive film or the film for a predetermined time. Here, a polyester film is put on the placed laminated glass and heated under a reduced pressure at a predetermined temperature according to the adhesive film or the film for a predetermined time. The polyester film is used to prevent air leakage under reduced pressure, and has a thickness of about 100 μm and a size larger than the laminated glass so as to cover the entire laminated glass including the peripheral portion. In the case of the adhesive film of this example, heating is performed at about 120 ° C. for about 30 minutes. As a result, the first and second adhesive films 5a and 5b are melted, and the melted adhesive 5c (see FIG. 2C) enters the gap between the glass pieces 3 to fix and fuse the glass pieces 3 on both sides. The first and second glass plates 2a and 2b are bonded and integrated. Thereafter, the mixture is cooled to 40 to 50 ° C., and the reduced pressure is released. Note that the first glass plate 2a and the second glass plate 2b may be tempered glass.
[0028]
Next, as shown in (C), a sealing seal 4 such as silicon is attached to the outer peripheral edge of the laminated glass 1. Instead of the sealing seal 4, as described above, a frame material previously provided on the periphery of the glass plate may be used as the sealing material so as to lay the glass piece 3 slightly inside the outer periphery of the laminated glass 1. Alternatively, the glass piece 3 may be spread to the entire outer peripheral edge with or without the frame material, and after the subsequent heat treatment, the outer peripheral edge may be shaved to trim the outer shape and the sealing seal 4 may be attached.
[0029]
【The invention's effect】
As described above, in the present invention, since the solid particles can be freely arranged, a pattern can be freely expressed, and various patterns can be drawn. Therefore, the range of decorativeness is expanded, and the design is improved. Further, by scattering amorphous solid particles, the reflected light is changed according to the angle of the light, and the glitter and the luminescent spot are changed, so that a pattern rich in change is obtained according to the viewing angle.
[0030]
In addition, due to refraction or reflection of light by the particles of the glass plate, for example, when a decorative plate made of laminated glass is irradiated with light, a glitter or a change in brilliancy occurs, and the decorativeness is improved.
[0031]
In addition, it is possible to manufacture a decorative plate using pieces of unnecessary tempered glass, such as pieces of unnecessary portions, which are inevitably generated in the production of tempered glass products, and it is necessary to manufacture tempered glass sandwiched in the middle. Since there is no such material, productivity is improved, resources can be saved by recycling, environmental problems can be contributed, and costs can be reduced.
[0032]
Further, for example, since solid particles can be freely arranged on a thermoplastic adhesive film at normal temperature, a pattern can be freely expressed, and various patterns can be drawn. Thereafter, the laminate composed of the adhesive film and the plate material sandwiching the solid particles is heat-treated to dissolve the adhesive film, and the fixed particles can be fixed by welding. As a result, a decorative plate having a wider decorative range and an improved design can be obtained.
