Description

Structures, multi-layer glazing and laminates

The present disclosure relates to a structure, a multi-layer glass window, and a laminate.

As a well-known type of window used in buildings such as houses and houses, there is a double-glazed window using a double-glazed glass having excellent thermal insulation performance (for example, refer to Patent Document 1).

The multi-layer glass includes: two glass plates facing each other across a hollow layer; a spacer, which is interposed between the two glass plates along the ends of the two glass plates in order to ensure the distance between the two glass plates; and a sealing material, The ends of the two glass plates are bonded and fixed to each other on the outer peripheral side of the spacer. The ends of the multi-layer glass are glazing channel), etc., are held in the sash that becomes the frame of the window.

In the highly heat-insulating type of double-glazed glass, a heat insulating gas such as argon is sealed in the hollow layer, so as the sealing material, a polysulfide-based sealing material that does not allow gas to pass through is generally used. The polysulfide-based sealing material contains a plasticizer for imparting flexibility to the sealing material. [Prior Art Literature] [Patent Literature]

Patent Document 1: Japanese Patent Laid-Open No. 2014-202055

[The problem to be solved by the invention] In recent years, in order to improve the weight reduction, impact resistance, etc. of the multiple glazing, a laminated body may be used instead of the glass plate constituting the multiple glazing. As an example of the structure of a laminated body, the structure which laminated|stacked the resin plate which becomes a core material, and a thin glass plate via an adhesive layer is mentioned. By using such a laminated body, the advantages of the resin plate, such as a specific gravity smaller than that of a glass plate, and a strong resistance to physical shock, can be appropriately exerted by the multilayer glass.

However, when the laminated body is used as described above, the following problems to be solved arise. That is, the adhesive layer of the laminated body absorbs moisture in the environment, becomes cloudy and loses transparency, or the adhesive force decreases and peeling occurs.

Furthermore, such problems do not arise only with multi-glazed windows. This problem also occurs when a laminated body is used instead of a glass plate in a structure other than the multi-layer glazing (for example, a platform door of a railway platform, a digital signage cover, etc.).

In view of the above circumstances, the technical problem to be solved is to prevent the adhesive layer of the laminated body from absorbing moisture in the environment in the structure having the laminated body as a constituent part. [Means of Solving Problems]

A structure for solving the above-mentioned problems includes a laminated body including a plate-shaped core material and a glass plate superimposed on the core material via an adhesive layer; and a frame body holding an end of the laminated body, and the structure body It is characterized in that the exposed part of the adhesive layer exposed on the outer surface of the laminated body at the edge part of the laminated body is covered with the metal foil.

In the structure, the exposed portion of the adhesive layer exposed on the outer surface of the layered body at the end portion of the layered body is covered with metal foil. Thereby, it can prevent that the adhesive layer of a laminated body absorbs the moisture of an environment.

In the above-mentioned structure, a covering member containing a plasticizer and disposed between the end portion of the laminate and the frame body may be included, and the metal foil may be interposed between the exposed portion of the adhesive layer and the interface of the covering member.

When the covering member contains a plasticizer, in the exposed portion of the adhesive layer exposed on the outer surface of the laminate, and the interface with the covering member, the plasticizer oozes out to the adhesive layer, and the adhesive layer may be discolored or peeled off. Danger. However, if the metal foil is interposed between the exposed portion of the adhesive layer and the interface of the covering member, the above-mentioned problem can be reliably eliminated.

In the above structure, the covering member is preferably a sealing material containing a plasticizer.

If it is set in this way, gas etc. can be made difficult to pass through by a sealing material, and a laminated body can be fixed firmly in a structure.

In the said structure, it is preferable that a core material consists of a resin board, and the exposed part of the resin board exposed on the outer surface of a laminated body is covered with a metal foil.

With such a setting, the presence of the metal foil can reliably eliminate the possibility that the plasticizer contained in the covering member oozes out to the resin sheet, and the resin sheet is discolored or peeled off.

In the structure, preferably the metal foil is an aluminum foil.

If it is set in this way, since an easily available and inexpensive aluminum foil is used as a metal foil, the manufacturing cost of a structure can be suppressed.

In the above-mentioned structure, it is preferable that the metal foil is attached to the end of the layered body by an adhesive.

By setting in this way, the metal foil can be brought into close contact with the end portion of the laminate, so that the bleeding of the plasticizer to the adhesive layer or the resin plate can be avoided more reliably.

In the said structure, it is preferable to superimpose a glass plate on the surface side and the back surface side of a core material via an adhesive layer, respectively.

If it is set in this way, a laminated body will be in the state which has a symmetrical structure on the front side and the back side with reference to a core material. Thereby, the possibility of warpage of the laminated body can be eliminated as much as possible.

In addition, according to the multi-layer glazing including the structure, the above-mentioned effects can be obtained in the same manner.

Moreover, the laminated body for solving the above-mentioned problems includes a plate-shaped core material and a glass plate superimposed on the core material via an adhesive layer, and is characterized in that the end portion of the laminated body is on the outer surface of the laminated body. The exposed portion of the exposed adhesive layer is covered with metal foil.

In the present layered product, the exposed portion of the adhesive layer exposed on the outer surface of the present layered product at its end is covered with metal foil. Therefore, when this laminated body is used for the structure (multilayer glass window etc.) which uses a laminated body as a component, the effect mentioned above can be acquired similarly. [Effect of invention]

According to the structure, the multi-layer glazing, and the laminate of the present disclosure, the adhesive layer of the laminate can be prevented from absorbing moisture in the environment.

Hereinafter, the structure, the multi-layer glass window, and the laminated body of the embodiment will be described with reference to the drawings.

FIG. 1 shows a double glazing 1 as an example of a structure. As shown in the figure, the double glazing 1 includes a double glazing 2 , a molding 3 attached to the end of the double glazing 2 , and a sash 4 serving as a frame that holds the end of the double glazing 2 via the molding 3 .

The multi-layer glass 2 includes a laminated body 6 and a glass plate 7 facing each other with the hollow layer 5 interposed therebetween, and a spacer 8 along the end portions 6a, 7 of the two layers 6 and 7 in order to maintain the distance between the laminated body 6 and the glass plate 7 . The end portion 7a is interposed between the two parts 6 and 7; the primary sealing material 9 is used to connect the spacer 8 to the laminated body 6 and the glass plate 7 respectively; The outer peripheral side is a covering member for adhering and fixing the end 6 a and the end 7 a of the laminated body 6 and the glass plate 7 , and the metal tape 11 covering the end 6 a of the laminated body 6 .

A heat insulating gas (eg, argon, air, etc.) is sealed in the hollow layer 5 .

The laminate 6 includes a resin plate 12 serving as a core material, and glass films 14 and 14 respectively superimposed on the front and back sides of the resin plate 12 via the adhesive layer 13 . In addition, in this embodiment, although a single resin plate 12 is contained in the core material, it is not limited to this. As a modification of the present embodiment, a core material may be obtained by stacking a plurality of resin plates.

As the resin plate 12, for example, a polycarbonate plate can be used. The glass film 14 has an area slightly smaller than that of the resin plate 12 , and the entire circumference of the end of the resin plate 12 protrudes from the end of the glass film 14 . Thereby, the end portion of the glass film 14 can be preferably protected from impact and the like. In addition, as a modification of this embodiment, the resin plate 12 and the glass film 14 may have substantially the same area.

Regarding the material of the adhesive layer 13, for example, ethylene vinyl acetate copolymer resin (EVA), polyvinyl butyral resin (PVB), and ultraviolet (Ultraviolet, UV) curing resin can be preferably used, and other Acrylic adhesives, silicone adhesives, rubber adhesives, UV curable acrylic adhesives, urethane adhesives, UV curable epoxy adhesives, thermosetting epoxy adhesives , Thermosetting melamine adhesive, thermosetting phenolic adhesive, etc.

A part of the next layer 13 is exposed on the outer surface of the layered body 6 , and this part constitutes the exposed part X (the part indicated by the thick line in FIG. 1 ). Similarly, a part of the resin plate 12 is exposed on the outer surface of the layered body 6 , and this part constitutes the exposed part Y (the part indicated by the thick line in FIG. 1 ). Furthermore, in the modified example described above in which the resin plate 12 and the glass film 14 have substantially the same area, the adhesive layer 13 may not be exposed on the main surface of the laminate 6 but only on the end surface of the laminate 6 . constitute.

The glass plate 7 has substantially the same area as the laminated body 6 , and is arranged so as to be substantially parallel to the laminated body 6 . In addition, as a modification of this embodiment, the laminated body 6 may be used instead of the glass plate 7 . That is, the two laminated bodies 6 may face each other with the hollow layer 5 interposed therebetween. However, from the viewpoint of securing the rigidity of the multiple glass 2 , it is preferable to use one of them as the laminated body 6 and the other as the glass plate 7 via the hollow layer 5 .

The spacer 8 is formed in a hollow shape, and the desiccant 15 is filled therein. In addition, through holes 16 are formed in the spacer 8 , and the space from the hollow layer 5 to the inside of the spacer 8 passes through the through holes 16 to form a continuous space. Therefore, the heat insulating gas in the hollow layer 5 is dried by the desiccant 15 through the through holes 16 .

The primary sealing material 9 is interposed between the side surface of the spacer 8 and the main surface of the laminate 6 and between the side surface of the spacer 8 and the main surface of the glass plate 7 .

The secondary sealing material 10 is a sealing material. The secondary sealing material 10 contains a polysulfide-based plasticizer. The secondary sealing material 10 is filled in the recessed part formed by the main surface of the laminated body 6 , the outer peripheral surface of the spacer 8 , and the main surface of the glass plate 7 . Furthermore, the secondary sealing material 10 covers the end surface of the laminated body 6 and the end surface of the glass plate 7 from the outer peripheral side. In addition, as a modification of this embodiment, a sealing material containing a plasticizer other than a polysulfide type can also be used.

The metal tape 11 is attached along the entire circumference of the end portion 6 a of the laminated body 6 . In addition, the metal tape 11 covers the end portion 6 a of the layered body 6 continuously from the inner main surface of the layered body 6 (the edge of the glass film 14 on the inner side) to the outer main surface (the outer main surface) including the end surface of the layered body 6 . the edge of the glass film 14). Thereby, the metal tape 11 is in a state of being interposed between the interface between the exposed portion X of the adhesive layer 13 and the secondary sealing material 10 and the interface between the exposed portion Y of the resin plate 12 and the secondary sealing material 10 . That is, the exposed part X and the secondary sealing material 10, and the exposed part Y and the secondary sealing material 10 are respectively separated by the metal tape 11 and are in a non-contact state. In addition, the portion of the metal tape 11 covering the outer main surface of the laminated body 6 may be omitted, and the metal tape 11 may be interposed at the interface between the exposed portion X and the secondary sealing material 10 at a minimum.

FIG. 2 shows only the laminated body 6 and the metal strip 11 among the components of the multi-layer glazing 1 . As shown in the figure, the metal tape 11 is formed by overlapping the metal foil 11a and the adhesive 11b. The kind of metal constituting the metal foil is not particularly limited, but in this embodiment, aluminum foil is used. Moreover, as the adhesive agent 11b, the adhesive agent which does not react with the adhesive layer 13 is used, and an acrylic adhesive agent is used in this embodiment.

As shown in FIG. 1 , the molding 3 is interposed between the multi-layer glass 2 and the sash 4 to fix both of them 2 and 4 . The fillet 3 is made of polyvinyl chloride or the like, for example. The sash 4 is made of aluminum, for example.

Hereinafter, the main functions and effects of the multi-layer glazing 1 (structure) will be described.

In the multilayer glazing 1 , the exposed portion X of the adhesive layer 13 exposed on the outer surface of the laminated body 6 at the end portion 6 a of the laminated body 6 is covered with the metal tape 11 (metal foil 11 a ). Thereby, the adhesive layer 13 of the laminated body 6 can be prevented from absorbing moisture in the environment. In addition, in the multilayer glazing 1 , the metal tape 11 (metal foil 11 a ) is interposed between the exposed portion X of the adhesive layer 13 exposed on the outer surface of the laminate 6 and the interface of the secondary sealing material 10 . The presence of the metal tape 11 can prevent the occurrence of a problem in which the plasticizer contained in the secondary sealing material 10 oozes out to the adhesive layer 13 and the adhesive layer 13 is discolored or peeled off.

Here, in the above-mentioned embodiment, the multilayer glass window is described as an example of the structure, but the present invention is not limited to this. For example, the structure may also be a door such as a platform door of a railway platform, or a digital signage cover. Furthermore, these structures have a laminated body as a constituent part, and have an exposed portion of the adhesive layer exposed on the outer surface of the laminated body, and a covering member containing a plasticizer (for example, disposed at the end portion and the holding end of the laminated body) In the case of a structure in which a sealing material, etc., between the frame bodies of the parts is adjacent to each other, the metal foil may be interposed at the interface between the exposed part and the covering member.

Hereinafter, examples other than the above-described multilayer glazing 1 will be given as examples of the structure. In the description of the sliding door 17 , the sliding door 18 , and the vehicle window 19 listed below, the sliding door 17 , the sliding door 18 , and the vehicle window 19 will be described with respect to the elements that are substantially the same as those described in the above-mentioned multi-glazing 1 . The drawings referred to in the description of the above are denoted by the same symbols, and repeated descriptions are omitted.

FIG. 3 shows a sliding door 17 as an example of a structure. This sliding door 17 is used for, for example, a platform door, and is slidable in the vertical direction with respect to the paper surface. The sliding door 17 includes: the laminated body 6; a metal belt 11 covering the end portion 6a of the laminated body 6; a frame 20 as a frame body for holding the end portion 6a; the covering member in between.

An opening 20 a is formed at the upper end of the frame 20 , and the end 6 a of the layered body 6 is accommodated in the frame 20 through the opening 20 a. The sealing material 21 is composed of, for example, a rubber gasket, and covers the metal tape 11 in a state of being filled up to the gap formed between the end portion 6 a of the laminate 6 and the frames 20 . The sealing material 21 may contain a plasticizer like the secondary sealing material 10 of the multi-layer glass window 1, or may not contain a plasticizer.

FIG. 4 shows a sliding door 18 as an example of a structure. The sliding door 18 is different from the sliding door 17 in that the sealing material 21 does not cover the metal strip 11 , but blocks the opening 20 a of the frame 20 above the metal strip 11 ; and the spacer 22 is interposed between the laminated body 6 The end face and the frame 20 are mutually.

The sealing material 21 is filled up to the gap formed between the periphery of the laminated body 6 and the openings 20 a of the frame 20 .

FIG. 5 shows a vehicle window 19 as an example of a structure. The vehicle window 19 is a window in which a glass plate, which is a component of the glass window, is replaced with a laminated body. The vehicle window 19 includes a laminate 6 , a metal band 11 covering an end portion 6 a of the laminate 6 , a frame 23 serving as a frame for holding the end portion 6 a , and a covering member interposed between the end portion 6 a and the frame 23 . Extrusion member 24 .

An opening 23a is formed in the upper end of the frame 23, and the end 6a of the layered body 6 is accommodated in the frame 23 through the opening 23a. The pressing member 24 is made of, for example, rubber, and is filled up to the gap formed between the end portion 6 a of the layered body 6 and the frame 20 . The laminated body 6 is pressed by the pressing member 24 . The extrusion member 24 may contain a plasticizer like the secondary sealing material 10 of the multi-layer glazing 1, or may not contain a plasticizer. [Example 1]

Six sheets of laminates with a length and width of 300 mm×300 mm were prepared, and three of the six sheets were covered with a metal tape made of an aluminum foil and an adhesive to cover the ends of the laminates, which were used as examples. . On the other hand, about the remaining three pieces, the edge part of the laminated body was not covered with a metal tape, but was exposed, and it was set as a comparative example.

The respective layered bodies of the Examples and Comparative Examples were subjected to repeated treatments of one cycle of immersion in water at 55°C and drying at a temperature of 40°C. The immersion time in water per cycle was set to 7 days to 10 days, and the cloudiness of the edge of the layered body accompanying the immersion was confirmed. The drying time per cycle was set to 2 to 3 days, and the disappearance of white turbidity accompanying drying was confirmed.

As a result of repeating the above-mentioned treatment, in the comparative example, when the total immersion time reached 17 days, all the three laminates were peeled off at the edges. On the other hand, in the Example, when the total immersion time reached 34 days, one of the three laminates was barely peeled at the edge.

The reason for obtaining the above-mentioned results is presumably because, in the examples, the exposed portion of the adhesive layer exposed on the outer surface of the laminate was covered with the metal tape, thereby preventing the adhesive layer from absorbing moisture as much as possible. [Example 2]

In the same manner as in the above-mentioned [Example 1], a three-piece layered product serving as an example and a three-piece layered product serving as a comparative example were prepared.

After the laminates of the examples and comparative examples were left to stand for a predetermined number of days in an environment with a temperature of 55°C and a humidity of 95%, they were cooled to a temperature of about 30°C for 5 hours or more, and the edges of the laminates were checked for cloudiness and turbidity. stripped.

In the confirmation after being left to stand in the environment for 16 days, cloudiness and peeling did not occur in the three Examples and the three Comparative Examples. However, in the confirmation after being left to stand in the environment for 32 days, cloudiness and peeling occurred in all the three Comparative Examples, but on the other hand, cloudiness and peeling did not occur in all the three Examples. Furthermore, with respect to the three examples, the cloudiness and peeling did not occur even in the confirmation after being left to stand in the environment for 56 days.

The reason for obtaining the above-mentioned results is presumed that, in the examples, the exposed portion of the adhesive layer exposed on the outer surface of the laminate was covered with the metal tape, thereby allowing the adhesive layer to be placed to absorb moisture in the environment as much as possible.
