2. Description of the Related Art Conventionally, a transparent or colored transparent shaped plate glass is provided with a pattern by an embossed roller or a special pattern by sandblasting. All of these methods make the surface of the glass plate uneven, but the former uses an expensive engraved roller, so it is not suitable for small quantities and many types, and the sandblasted glass is mainly composed of artistic patterns. Therefore, it is not suitable for industrial mass production. In all of these conventional shaped plate glasses, since the glass plate itself is provided with irregularities, the recessed portion has a notch, the strength is significantly reduced, and the glass is easily broken.

[0003]

DISCLOSURE OF THE INVENTION The present inventors aimed at providing a shaped glass sheet whose strength did not decrease at all.
We have been studying the manufacturing method of shaped glass that does not directly add irregularities to the glass plate, paying attention to the method of transferring the pattern of the transfer plate on the glass plate with film and adhesive, and further studying, the strength jumped as a result As a result, the present invention has been achieved in which a shaped plate glass which is improved in terms of safety, has high safety and is visually unique can be produced with excellent productivity even in a small quantity and a large variety.

[0004]

According to one aspect of the present invention, a transparent glass plate or a plastic plate is used as a base plate, and a transparent plastic film is laminated on the base plate via an adhesive layer. When manufacturing the board, a transparent, viscoelastic
A transfer plate on which a plastic film is placed via a certain liquid adhesive and has an uneven pattern with a depth of 0.1 to 0.5 mm
Is pressed with a vacuum pressure , and then the liquid adhesive layer is cured to bond the plastic film to the base plate and at the same time to impart an uneven pattern to the plastic film.
This is a method for producing a light diffusing laminate.

[0005] 2 of the present invention, see-through laminate characterized by adhering the transparent glass plate or plastic plate through a further transparent adhesive to the uneven pattern surface of the plastic film obtained by the above process It is a manufacturing method of.

Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a cross-sectional view for explaining a method of manufacturing a laminated plate of the present invention, and FIG. 2 is a cross-sectional view of a laminated plate obtained by the method of FIG. In the figure, 1 is a base plate made of glass or plastic, 2 is a plastic film (hereinafter abbreviated as a film), 3 is an adhesive layer, 4 is a transfer plate having an uneven pattern,
5 is a terminal spacer, 6 is a gap formed between the film and the uneven surface of the transfer plate, 7 is a vacuum generator, and 8 is a vacuum seal material. As shown in FIG. 1, a transfer plate 4 is placed on a film 2 laminated on a base plate 1 via an adhesive 3 with the uneven surface facing the film, and the transfer plate 4 in the gap 6 formed between the film 2 and the uneven surface is formed. By evacuating the air with the vacuum generator 7, the transfer plate 4
Is faithfully transferred to the film. In this state, the adhesive is cured to fix the uneven pattern to the film surface.
Pressing the transfer plate 4 with a vacuum pressure eliminates incomplete transfer of the pattern due to bubbles remaining in the edge of the transfer plate.

FIG. 2 is a cross-sectional view of the laminated plate produced by the above-mentioned manufacturing method. The laminated plate is composed of a film 2 ′ having an uneven pattern transferred to a base plate 1 via a cured adhesive layer 3 ′.

As the base plate 1, a transparent glass plate is generally used, but a plastic plate is also used.
This glass plate is generally directed to a transparent float glass, wearing colored glass, steel-containing glass, a line containing glass, heat reflecting glass, may be a heat absorbing glass, etc., and tempered glass with enhanced the glass , Semi-tempered glass, chemically tempered glass and the like can also be used. Plastic board
It may be worn color plastic, or may be a functional plastic such as heat-absorbing. The material of the plastic plate is not particularly limited, and polycarbonate resin, MMA resin, AS resin, ABS resin, PVC resin, FRP resin and the like are preferably used. The thickness of the base plate 1 is not particularly limited, but generally a thickness of about 3 mm is often used to maintain rigidity.

[0009] As the film 2 for imparting an uneven pattern,
Generally transparent thermoplastic polyester film, polycarbonate film, but vinyl films and the like chloride is used, may be a wear color film, further functional film for example heat-reflecting film, a heat ray absorption film, transparent conductive film, polarizing film, tone Optical films, hard-coated films and the like can also be used. The thickness of the film is desirably such that the film can be faithfully pressed against the irregularities of the transfer plate by vacuum pressure and has a small Young's modulus. Generally, a polyester film having a thickness of 25 to 75 μm is preferable.

The adhesive 3 is preferably a transparent, viscoelastic liquid before curing, such as a photopolymerization type or a heat polymerization type.

As the transfer plate 4, a plate glass having an uneven pattern is generally used, but a plastic plate can also be used. In addition, the same function as that of the transfer plate can be provided by stacking the etching plate having the pattern etched thereon and the holding plate. The etching template is a thin plate obtained by chemically etching a metal thin plate such as stainless steel or brass to remove its pattern. In addition, a template used for a silk screen or the like can also be used. Since the thicker the etching template, the deeper the uneven pattern of the product, the more the thickness of the plate is 0.1 to 0.5 mm, but it is not specified.
Float glass is generally used as the transfer plate and the holding plate. However, water between the film 2 is removed by a vacuum generator 7 to eliminate air bubbles due to residual air, and water glass is used to faithfully transfer the pattern. It is desirable to do.
Since the water glass has a myriad of fine convex surfaces, when it is used as a transfer plate, it creates a continuous gap with the surroundings between the film 2 and makes it easy to bleed air. And a gap between the film 2 and the surroundings is formed to make it easier to extract air. As the unevenness of the water glass, a fine one is used so as not to be transferred to the film 2. However, depending on the size of the unevenness, it can be used as a ground pattern.

The terminal spacer 5 serves as a spacer for preventing the liquid adhesive 3 from leaking from the periphery and for defining the average layer thickness of the adhesive, and preferably has a low moisture permeability. If it has such characteristics as materials,
The structure is not specified. The vacuum sealing material 8 is used to remove air in the gap 6 between the film 2 and the transfer plate 4 so that the laminated plate (1,
Any structure capable of simultaneously sealing the periphery of the transfer plate 4 and the periphery of the transfer plate 4 may be used. For example, a vinyl chloride tape having an adhesive layer on one surface is used.

FIG. 3 shows an etching template 9 instead of the transfer plate 4.
A production method having the same function as that of the transfer plate 4 is shown. Other manufacturing methods are the same as those in FIG. FIG.
FIG. 3 is a cross-sectional view of a laminated plate prepared by using an etching template.

FIG. 5 is a cross-sectional view for explaining the manufacturing method according to the second aspect of the present invention. The adhesive 3 is further flowed on the film 2 'on which the uneven pattern shown in FIG. A plate or a plastic plate 11 is laminated, the entire periphery is sealed with a vacuum sealing material 8, and the air in the gap 6 is evacuated by a vacuum generator 7 so that the adhesive 3 is separated from the film 2 'and the glass plate. Filled between 11 The adhesive is cured in this state. FIG. 6 shows a laminated plate produced by the above-described method, in which a film 2 'having an uneven pattern transferred between two glass plates or plastic plates 1 and 11 via a cured adhesive 3'. 3 shows a laminate.

Although the above description has been made with reference to a laminated plate on a flat plate, the present invention can be similarly applied to a laminated plate having a curved surface.

[0016]

According to the present invention, the base plate itself is not provided with irregularities, and the plastic film is adhered, so that the strength is dramatically improved and a highly safe shaped plate glass or shaped plate plastic plate is obtained. It can be easily manufactured with excellent productivity. Further, for example, by coloring a plastic film or changing its color, an arbitrary colored product can be obtained, and the change of the concavo-convex pattern can be achieved only by changing the transfer plate. Further, if a heat ray reflective film having a metal vapor deposition surface is used as the plastic film, the light reflected on the vapor deposition surface is diffused due to unevenness, and light pollution which reflects a solar image by a mirror surface is reduced. Normally, the see-through light is diffused, and the image looks blurred like a general template glass.However, when a heat ray reflective film is laminated between two glass plates, the reflected light is diffusely reflected as above,
The perspective image has the special effect of appearing clear.
