Description

Description: TECHNICAL FIELD The present invention relates to a method for manufacturing a curved translucent transparent plate used for a window, a solarium, a top light, a sash of a building, a house, etc., and a daylighting part of a vehicle, etc. It is a thing.

(Prior art and its problems) In general, when sunlight is excessively incident from a window of a sash in a solarium, a building, a house, etc., the contrast between light and dark in a room where light is applied becomes excessively strong,
It is unpleasant because it is dazzling and makes it difficult to see things, and it is harmful because it causes the room temperature to become unnecessarily high and promotes the brown color of furniture and other interiors. Therefore,
Ideally, the sunlight from the daylighting section should enter the room in a soft state. Conventionally, sunshades and blinds have been known as means for dealing with this. However, this is a light-shielding means, and almost all the light is shielded, so that it has a drawback that it has a poor light-reducing function and the operation is troublesome. Further, since there is no function of protecting the translucent plate of the light collecting part for each light shielding means, the translucent plate must be protected by another means.

To cope with this, it has been considered to bond two light-transmitting plates through an optical filter layer or to use a liquid resin agent as an adhesive for the light-transmitting plates. However, in the technique of adhering a curved light-transmitting plate with a liquid adhesive resin agent, the following problems must be overcome.

(A) What should be done with the seal to prevent the liquid adhesive resin agent injected into the space inside the transparent plate with different curvatures from leaking out?

(B) What is the simplest and surest way to hold the translucent plate firmly against liquid pressure until the injected liquid adhesive resin agent hardens?

(C) How to deal with processing errors and distortion deformation of the curved surface of the transparent plate having different curvatures.

(D) What should be done to obtain effects such as earthquake resistance and soundproofing as a whole?

(E) How to harmonize with the multilayer structure.

(Object of the Invention) The present invention solves the above technical problems, and can prevent sunlight from dazzling, overheating indoors, browning of furniture, etc. by filtering the sunlight, and is strong and easy to handle. It is a technical problem to provide a method for manufacturing a curved transparent light-transmitting plate having excellent properties.

(Means for Solving the Problems) In order to solve the above problems, the combined translucent plate used in the daylighting part of the present invention is used in the daylighting part of buildings, vehicles, and the like, and two translucent plates inside and outside. A method for producing a curved light-transmitting transparent plate having an adhesive layer for adhering the same, and an optical filter paint layer formed between at least the inner side of the outer light-transmitting plate and the adhesive layer. After forming an optical filter paint layer on the back surface of at least the outer transparent plate of the curved light-transmitting plates, a sticky thread core with viscosity is attached to the mating surface of the peripheral edge of one of the transparent plates. Stick the butyl seal material in a part of the opening and the other part in a continuous manner, and attach the other transparent plate to this via the butyl seal material, and then sandwich the transparent plate with a jig. Attached and fixed, the space formed inside the sealing material from the opening A liquid adhesive resin agent obtained by mixing the above catalyst into a liquid acrylic resin that is semi-cured by a catalyst is injected into the resin, and the adhesive resin agent is semi-cured to bond and integrate the two translucent plates. And

(Operation and Effect of the Invention) As described above, in the present invention, the sticky butyl seal material containing a viscous rod-shaped core is used as the seal material between the translucent plates. Since this butyl sealing material has viscosity, it remains in a deformed state even if external force is removed. When a stick-shaped sealing material is attached to a light-transmissive plate, it deforms in response to its curved shape. As it is left as it is, it is easy to handle,
Even when sandwiching both translucent plates with a clamping jig, the pressing force deforms in response to shape errors and distortion caused by the curved surface shape, so the translucent plate and the butyl seal material are sealed without any gaps. Moreover, since the butyl seal material contains the thread core, it does not break. Therefore, the liquid adhesive resin agent does not leak from the space.

Further, since the viscous rod-shaped sealing material is used, it is possible to easily and surely maintain the sealed state by simply sandwiching and fixing the two translucent plates with a sandwiching jig, and the work is easy. Therefore, the curved transparent light-transmitting plate can be easily manufactured.

Furthermore, since the adhesive layer is made of semi-cured liquid resin, it is possible to deal with processing errors and distortion deformation of the curved surface of the light-transmitting plate, and to obtain a combined light-transmitting plate with excellent heat insulation, soundproofing and earthquake resistance. be able to.

In addition, by first forming the optical filter layer on the light-transmitting plate and then forming the adhesive layer, the above two layers could be reasonably layered between the curved light-transmitting plates.

Moreover, since the optical filter coating layer is arranged outside the adhesive layer made of the adhesive resin agent, infrared rays are absorbed before reaching the adhesive layer, the overheating of the adhesive layer is prevented, and the durability of the laminated translucent plate is improved. It is possible to improve the sex.

Further, when the outer light-transmitting plate and the inner light-transmitting plate are overlapped and bonded to each other, since an optical filter paint layer is formed in advance at least inside the outer light-transmitting plate, an adhesive resin agent forming the adhesive layer. Will be injected between the optical filter paint layer and the inner light-transmitting plate, because both the optical filter paint layer and the adhesive layer are made of synthetic resin,
They are well compatible with each other and do not cause problems such as peeling. Therefore, the inner and outer light-transmitting plates can be firmly and reliably joined together.

In addition, in the combined translucent plate obtained by the above-mentioned manufacturing method, the inner and outer translucent plates are integrally bonded by the adhesive layer, so that the heat insulating and soundproofing effects are high and the strength is high. In addition, since the optical filter paint layer is formed on the combined translucent plate, glare,
It is possible to prevent indoor overheating and browning of furniture and the like, and since the optical filter coating layer is protected between the inner and outer light-transmitting plates, it is not peeled off by an external force and is easy to handle.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 2 (a) and 2 (b), reference numeral A is a bay window provided on the building frame, and B is a top light. Both of the exit window A and the top light B are provided with a translucent plate C made of glass, synthetic resin or the like inside the frame of the window part 10 which constitutes the daylighting part. The translucent plate C has a curved shape. It is composed of a combined transparent plate. The lighting unit is not limited to a building, but may be a lighting unit in a vehicle such as a passenger car, a truck, or a ship.

As shown in FIG. 1, the translucent plate C includes inner and outer translucent plates 1,
2 is adhered via the adhesive layer 3, and the outer transparent plate 2
An optical filter paint layer 4 is formed between the inside of the and the adhesive layer 3.

The inner light-transmitting plate 1 is a light-transmitting plate containing nets and a wire net 5 is embedded therein. The inner light-transmitting plate 1 does not have to include the metal net 5.

The optical filter paint layer 4 is formed from a resin paint containing a color pigment as necessary. Such an optical filter paint layer 4 is, for example, alkyd resin and a solvent distilled from petroleum and purified to be weather resistant. It can be formed by applying a paint containing a pigment or the like. The color pigment is appropriately selected and used according to the purpose such as antiglare and overheat prevention. When the main purpose is to prevent UV rays, the color pigment is not included and the optical filter coating layer is used in a clear state.

The adhesive layer 3 is made of an adhesive resin. This can be formed, for example, by mixing a liquid acrylic resin with a catalyst and injecting it between the inner and outer translucent plates 1 and 2 to semi-cure at room temperature. In this case, the liquid acrylic resin and the catalyst are mixed. The mixing may be carried out by a mixing / injection apparatus suitable for it, and the injection may be carried out in a continuous or batch system.

The curved transparent light-transmitting plate C can be manufactured by the following steps.

First, as shown in FIG. 3 (a), the outer light-transmitting plate 2 is housed in a paint container 6 containing a resin paint containing a color pigment, and the above-mentioned paint is pumped by a pump 7 and a spray gun 8. 2 is spray coated on the inside of the optical filter layer 4 in advance
Is formed (paint thickness of about 5 to 10 microns). Then, naturally dry for about 2 weeks. Next, as shown in FIG. 3B, a viscous rod-shaped butyl seal material 9 containing a thread core is attached to the inner peripheral edge of the outer light-transmitting plate 2 excluding a part 2a. Further, as shown in FIG. 3C, the inner light-transmitting plate 1 is fitted inside the outer light-transmitting plate 2, and the two inner and outer light-transmitting plates 1 and 2 are fixed by a sandwiching jig 11. . The distance between the two transparent plates 1 and 2 is about 2 mm. As a result, the peripheral portions of the inner and outer light-transmitting plates 1 and 2 are sealed by the butyseal material 9 except for a part 2a, so that the liquid adhesive resin agent 12 mixed with the catalyst is discharged from the opening formed by the non-sealing portion 2a. It may be injected into the space S inside the butyl sealant 9.
In addition, polymethylmethacrylate was used as the liquid adhesive resin agent 12, benzoyl peroxide and dimethylaniline were used as catalysts, and about 1% of benzoyl peroxide and dimethylaniline were added to 100 weight of polymethyl lutaacrylate. When used at room temperature, it was semi-cured after 5 to 6 hours. As a result, the adhesive layer 3 is formed, and the inner and outer translucent plates 1 and 2 are combined and integrated to form a combined translucent plate.

In the above-mentioned manufacturing method, a sticky butyl seal material 9 containing a viscous rod core is used as a seal material between the translucent plates 1 and 2.
Since this butyl seal material 9 has viscosity,
It will remain deformed even if external force is removed,
When the butyl sealing material 9 is attached to the translucent plates 1 and 2, it is deformed immediately in response to the curved surface shape, so that it is easy to handle and the sandwiching jig 11 is used to both the translucent plates 1 and 2. Even when sandwiched between the transparent plate 1 and the transparent plate 1, the pressing force deforms in response to shape errors and distortions caused by the curved surface shape.
The butyl seal material 9 and the butyl seal material 9 are sealed without a gap, and the butyl seal material 9 does not break because it has a core. Therefore, the liquid adhesive resin agent 12 does not leak from the space.

Further, by using the butyl seal material 9 in the form of a viscous rod, the two translucent plates 1 and 2 can be simply and securely fixed by sandwiching them with a sandwiching jig 12, and the sealed state can be reliably maintained, and the work is easy. Is. Therefore, the curved transparent light-transmitting plate C can be easily manufactured.

Further, since the adhesive layer is made of semi-cured liquid resin, it is possible to cope with processing errors and distortion deformation of the curved surfaces of the light-transmitting plates 1 and 2, and it is excellent in heat insulation, soundproofing and earthquake resistance. The board can be obtained.

Further, since the optical filter paint layer 4 is arranged outside the adhesive layer 3, infrared rays are absorbed before reaching the adhesive layer 3,
The adhesive layer 3 is prevented from overheating, and the durability of the laminated translucent plate can be improved.

Furthermore, when the outer light-transmitting plate 2 and the inner light-transmitting plate 1 are overlapped and bonded to each other, since the optical filter coating layer 4 is formed in advance at least inside the outer light-transmitting plate 2, the adhesive layer 3 is not used. The constituent resin agent 12 is the optical filter paint layer 4 described above.
Is injected between the inner transparent plate 1 and the inner transparent plate 1, but since both the optical filter coating layer 4 and the adhesive layer 3 are made of synthetic resin, they are well compatible with each other and do not cause problems such as peeling. . Therefore, the inner and outer translucent plates 1 and 2 are firmly fixed,
It can be surely combined.

Also, in the combined translucent plate obtained by the above manufacturing method, since the inner and outer translucent plates 1 and 2 are integrally bonded by the adhesive layer 3, the heat insulating and soundproofing effects are high and the strength is high. Further, since the optical filter paint layer 4 is formed on the combined translucent plate, it is possible to prevent glare, overheating of the room, and brown color of furniture, and the optical filter paint layer 4 is used for the inner and outer translucent plates. Because it is protected between 1 and 2, it is not peeled off by external force and is easy to handle.

Further, the optical filter coating layer in the present invention has the effect of the present invention if it is formed at least between the inside of the outer light-transmitting plate and the adhesive layer, but it is between the adhesive layer and the inner light-transmitting plate. If it is also formed, the optical filter function can be further improved.

Further, when mainly used for the purpose of preventing ultraviolet rays, it is possible to form the optical filter paint layer in a clear state without including a coloring pigment.
