Definitions
- the invention relates to a composite panel unit with at least one image layer between at least two plates, wherein an adhesive intermediate layer is provided on both sides for surface bonding of the image layer with adjacent plates, as well as a method for producing the composite panel unit according to the invention.
- the image layer can have any desired optical image, including, in particular, lettering.
- a laminated glass unit is already known from US Pat. No. 5,595,794, in which the photo is glued between two glass plates for archiving photoimage material with the aid of two polyurethane adhesive layers, thereby creating a five-layered composite.
- a laminated glass unit is only suitable for archiving in the interior and this only limited, since even at relatively small temperature fluctuations, the polyurethane adhesive layers of the laminated glass unit expand when heated, and thereby the enclosed between the two glass plates photo curls, resulting in an optical gives rise to a negative, unacceptable change in the photoimage included in the laminated glass unit.
- a somewhat different composite panel unit having a visible (motif) pattern is described in WO 95/00329 A1.
- a visible pattern is applied to a plastic film such as a polyvinyl butyral film by means of an epoxy resin-based ink and is dried on the polyvinyl butyral film prior to assembly of the composite unit. More specifically, a color layer is screen printed to make a pattern and only a single plastic film, i. Polyvinyl butyral film used to join two glass or plastic disks together.
- JP 56-45852 A discloses a process for the production of colored glass, wherein recesses are made by technical means in a resin layer into which finally the desired colors are injected.
- the aim of the present invention is now to provide a composite panel unit of the type mentioned, which even with temperature fluctuations, a visually flawless reproduction of the enclosed between the plates image layer guaranteed.
- this is also a composite panel unit are created, which can be used outdoors, such as facade glazing, windows and the like, and also withstand the occurring outside, significant temperature fluctuations.
- the composite panel unit according to the invention of the type specified in the introduction is characterized in that the two adhesion intermediate layers and / or panels adjoining one image layer each have a different thermal expansion behavior so that the image layer is tensioned due to the inhomogeneous composite with temperature changes.
- the image layer is kept taut even when heating the composite plate unit between the two plates.
- the composite panel unit For an optically attractive appearance of the composite panel unit, it is favorable if at least one panel is transparent or translucent.
- glass plates are provided as plates.
- the unwanted wave or blistering can be particularly reliably avoided if the two adhesive intermediate layers and / or plates of materials with different There are thermal expansion coefficients. This ensures that the image layer of the intermediate adhesive layer and / or the plate, which has the greater coefficient of thermal expansion remains reliably stretched even when heating the composite plate unit, with respect to the intermediate adhesive layer and / or the plate with the larger coefficient of thermal expansion slightly concave curvature of the entire composite panel unit takes place.
- an inhomogeneous plate / image layer / plate composite which results in a warp of the entire composite plate unit instead of a corrugation of the image layer trapped between the plates
- an inhomogeneous composite is created, if both sides of the adhesive intermediate layers of the same material, are provided with the same coefficient of thermal expansion, but the plates have a different material thickness.
- At least one intermediate adhesive layer is a film, preferably an ethylene-vinyl acetate copolymer (EVA) film, polyvinyl acetate (PVA) film, polyvinyl butyral (PVB) film or the like.
- EVA films have proven their worth in practice, since they do not require an autoclave to bond the glass plate to the image layer, unlike the known polyurethane films.
- ethylene-vinyl acetate copolymer films (EVA films) in particular films from Sekisui, Bridgestone and Takeda are preferred, with the S-LEX-EN film Sekisui the best results in terms of bond strength could be achieved.
- an intermediate adhesive layer consists of cast resin
- a reliable composite of the image layer is given with the adjacent glass plate
- a variety of types of cast resin can be used.
- an adhesive intermediate layer consists of silicone adhesive.
- an outer, on the narrow sides, on the circumference of the plates Insulating layer, preferably made of silicone, is provided.
- Such photos also have the advantage that they have polyester as a carrier material, and consequently with the two adjacent (glass) plates form an extremely resistant composite almost in the manner of bulletproof glass.
- the image layer enhances the acoustic insulation of the (glass) plates, making them particularly suitable for use as partitions.
- the image layer is transparent, translucent or opaque.
- the image layer may have a variety of substrates, wherein the carrier material in a transparent or translucid image layer mostly consists of triacetate or polyester, while in opaque image layers preferably polyester films or polyethylene paper is used as the carrier material.
- the erfin ⁇ tion proper composite plate unit can thus also be used very well as a light regulator, which regulates or reduces incident light.
- the composite panel unit has an area greater than 2 m 2 , preferably greater than 4.5 m 2 , it can advantageously be used for outdoor applications such as facades, windows and the like, which in this case gives the viewer from the outside an attractive appearance and at the same time reflects the incident light in the interior of the motif of the image layer similar to a slide projection.
- the composite plate unit is bonded under negative pressure.
- the image layer is cleaned on both sides before bonding, preferably degreased.
- the gluing of the image layer takes place with at least one plate in a synthetic material envelope.
- the plastic sleeve is evacuated with at least one plate to preferably substantially 0.8 bar prior to the gluing of the image layer, whereby advantageously also the humidity in the plastic envelope is reduced.
- a high moisture content in the composite panel unit is particularly disadvantageous when using Ilfochromfotos, as this lightness of the photo is impaired.
- the image layer only with a first plate, preferably in a plastic sleeve, is connected and only in a second method step, a second plate is connected after connecting the image layer with the first plate.
- an adhesive may be framed at the edge of the plate / image layer composite on the image layer side, thereby keeping the second plate spaced from the image layer to rest on the image layer, and the cavity thereafter with cast resin can be filled.
- Fig. 1 is a view of the laminated glass unit in an exploded, non-assembled position
- Fig. 2 is a view of the laminated glass unit in an assembled position
- FIG. 3A shows a portion of the section along the line III-III in Fig. 2.
- Fig. 3B also a portion according to the section III-III in Figure 2, but with a different adhesive intermediate layer.
- FIG. 4 shows a section of a laminated glass unit with two image layers.
- a laminated glass unit 1 is shown in a not yet assembled position, wherein the two glass plates 2 can be seen, between which an image layer 3 by means of both sides of the image layer 3 provided intermediate adhesive layers 4, 4 'is glued.
- the image layer 3 which is preferably an Ilfochrome photo, this is initially degreased on both sides to increase the adhesive capacity.
- the image layer 3 is applied with the interposition of an adhesive intermediate layer 4 on the glass plate 2.
- the second glass plate 2 with the interposition of a second adhesive intermediate layer 4 'on the glass plate / image layer composite 1' applied.
- the entire not glued laminated glass unit is then covered with a KunststoffStoff ülle or film (not shown) and sealed airtight.
- a vacuum pump is connected to the plastic sheath and thus generates a negative pressure of about 0.83 bar.
- the entire glass plates / image layer composite is "baked" in an oven.
- the plastic shell is removed.
- the image layer 3 can also first be produced with a glass plate 2 to form a composite 1 ', as is shown in FIG. 1 with the dashed dividing line 5.
- the second glass plate 2 can be placed on the image layer side with the aid of a glue applied like a frame, and the enclosed cavity can be filled with casting resin. Only in a second method step, the second glass plate 2 is then bonded by means of the second cast resin adhesive intermediate layer 4 'with the already glued glass plates / image layer composite 1'.
- a laminated glass unit 1 After bonding, a laminated glass unit 1, as shown in Fig. 2, wherein after bonding to the narrow side 6 on the circumference of the glass plates 2, a silicone bond 7 is applied to reliably prevent moisture from the outside to the between the glass plates 2 enclosed image layer 3 can penetrate; Too high a moisture content in the laminated glass unit would, on the one hand, reduce the strength of the composite and, in addition, worsen the lightfastness of the image layer 3 when using an Ilfochrome photo.
- the two adhesive intermediate layers 4, 4 'shown schematically in FIGS. 3 a and 3 b are made of different materials, since an inhomogeneous composite is thus provided, whereby an unwanted wave formation of the image layer 3 between the two is produced when the laminated glass unit 1 is heated Glass plates 2 is prevented.
- an inhomogeneous glass plate / image layer / glass plate composite is in particular the different thermal expansion behavior and the different adhesiveness of the two adhesive intermediate layers 4, 4 'with the Image layer responsible.
- EVA ethylene-vinyl acetate copolymer
- PVA polyvinyl acetate
- PVB polyvinyl butyral
- a film of modified EVA has proven to be favorable, which is commercially available under the name S-LEX-EN film Sekisui.
- an adhesive intermediate layer of cast resin or silicone adhesive may also be provided, which has a material thickness of about 1 mm.
- the above-mentioned adhesive intermediate layers 4, 4 ' can be combined as desired to obtain a laminated glass unit 1 with different adhesive intermediate layers 4, 4'.
- the films 8 on both sides of the image layer 3 in different numbers of layers as adhesive intermediate layers.
- a single film 8 may be applied as an adhesive interlayer 4, while for bonding to a second glass plate 2, two films 8 for forming the adhesive interlayer 4 'are stacked.
- inkjet or laser printouts can also be used as image layer 3, it being possible in all cases for different carrier materials of image layers 3 to be used.
- image layer 3 can be used as a carrier material, for example paper, polyethylene paper or polyester films sold under the brand name Melinex.
- prints of positive on one of the abovementioned substrates are preferred because of their high lightfastness which are then developed using the silver bleaching process.
- the film Ilfochrom Ilford preferred here.
- prints of negatives may also be used on one of the abovementioned support materials, but these have a lower resistance to light.
- the two adhesion intermediate layers 4, 4 'provided for bonding comprise different materials, in particular with different coefficients of thermal expansion and different adhesiveness, whereby, instead of a wave formation of the image layer 3, the entire laminated glass unit 1 slightly warps when heated, but this curvature is so insignificant that it does not adversely affect the appearance of the laminated glass unit.
- FIG. 4 shows a section of a laminated glass unit with two image layers 3.
- adhesive intermediate layers 4, 4 ' are provided in this embodiment, each of the same material and with the same material thickness, however, the glass plates 2 with, for example, 2 mm, 4 mm and 6 mm different material thicknesses, so that results in a different thermal expansion behavior on each of the two sides of the image layers 3 and thus the image layers 3, even with strongly changing ambient temperatures, as often occurs in outdoor applications, such as facade or the like, stay reliably taut without it being too undesirable Wave or blistering comes.
- the laminated glass unit can also have three or more image layers, it is only essential that the image layers remain taut even with changing ambient temperatures.
