Definitions

  • the present invention relates to a method for producing an insulating glazing base body according to claim 1, a method for producing insulating glazing according to claim 9 and insulating glazing according to claim 10.
  • insulating glazing that is formed by a component composed of at least two panes of glass has proven itself. There is a cavity between the glass panes, which is usually sealed gas-tight and moisture-tight and provides improved sound and heat insulation.
  • triple insulating glazing is mostly produced and used for glazing, as it has better thermal insulation properties than double insulating glazing. It is customary here to establish the mechanical connection of the panes using spacer arrangements, via which the panes are connected to one another at a distance from one another.
  • a spacer which has a groove for inserting an inner pane.
  • An arrangement of spacers and an inner pane inserted into the spacer is also referred to below as an insulating glazing base body.
  • Such insulating glazing base bodies represent an important intermediate product in the manufacture of insulating glazing WO 2014/198431 A1 If the groove of the spacer has flexible side flanks, and the inner disk is inserted loosely into the groove of the spacer and held by the flexible side flanks without being rigidly connected to the groove. This allows any stresses that occur to be compensated.
  • This object is achieved by a method for producing an insulating glazing base body according to claim 1, a method for producing insulating glazing according to claim 9, and insulating glazing according to claim 10.
  • An essential core idea of the invention consists in the knowledge that by gluing the inner pane in the groove of the spacer arrangement, the mechanical stability of the insulating glazing base body can be significantly increased. It has surprisingly been found here that, despite the gluing of the inner pane in the spacer arrangement, no significant stresses occur, since the adhesive sufficiently compensates for the stresses. By gluing the spacer arrangement to the inner pane, the mechanical stability of the insulating glazing base body is significantly increased, which significantly improves the handling when producing insulating glazing. In addition, the insulating glazing base body according to the invention is significantly less prone to damage during transport.
  • the inventive concept of building the frame from spacers directly on the inner pane of the later insulating glazing is also advantageous in terms of dispensing with the corner connectors customary in the area of insulating glazing.
  • No corner connectors are used in the method according to the invention, which results in cost savings on the one hand and on the other hand, the high risk of breakage of the spacers, which is common with corner connectors, is avoided.
  • an arrangement comprising a spacer arrangement and an inner pane inserted into the spacer arrangement is referred to as an insulating glazing base body.
  • the insulating glazing base body can also have several spacer arrangements into which the respective edges of the inner pane are inserted.
  • the spacer assemblies form a frame around the inner pane, the pane contact surfaces of the spacer assemblies forming respective pane contact surfaces of the frame to which outer panes can be attached to form insulating glazing.
  • the arrangement of a spacer arrangement and the inner pane is primarily described below. The features described and the technical effects and advantages achieved with them can, however, also be transferred to an insulating glazing base body which has several spacer arrangements.
  • a spacer arrangement can also comprise several grooves into each of which an inner disk is inserted.
  • the inner pane preferably contains glass and / or polymers, particularly preferably quartz glass, borosilicate glass, soda-lime glass, polymethyl methacrylate and / or mixtures thereof.
  • the inner pane also preferably has a low-E coating.
  • the adhesive is a liquid or viscous adhesive.
  • a butyl acrylate adhesive for example, is preferably used here.
  • a liquid or viscous adhesive With a liquid or viscous adhesive, a simple implementation of the gluing process is made possible since only a correspondingly dosed amount of adhesive has to be introduced into the groove and the inner pane can then be inserted into the groove. Furthermore, slight adjustments to the arrangement can be made before the adhesive hardens, for example by slightly displacing a spacer along a pane edge.
  • the adhesive is an adhesive tape, preferably a double-sided adhesive tape, more preferably a double-sided foam adhesive tape.
  • tape there are several advantages to using tape. On the one hand, there is no need to dose the adhesive. Furthermore, when using a Adhesive tape achieves an instant adhesive effect, so that no drying time has to be planned in the formation of the insulating glazing base body. In addition, there is no risk of the adhesive entering into a chemical reaction with the spacer arrangement - this problem can arise if an adhesive that is unsuitable for the material of the spacer arrangement is used.
  • Double-sided foam adhesive tapes which have a reversibly deformable foam layer which is provided with an adhesive layer on both sides are particularly preferred.
  • the double-sided foam adhesive tape preferably has a layer of polyethylene foam (PE foam) which is provided on both sides with an adhesive layer, for example based on pure acrylate.
  • the thickness of the foam layer is preferably 0.5 mm.
  • the adhesive layers preferably have an application weight of 70 g / m 2 .
  • the inner pane is glued to a bottom surface of the groove. It has been found that, particularly when using the double-sided foam adhesive tape described above, the adhesion is so strong that the spacer arrangement does not become detached from the inner pane. If spacer arrangements are attached to all edges of the inner pane in this way, there is even no need to physically connect the spacer arrangements to one another, since the adhesive effect is sufficient to form a mechanically stable frame of spacer arrangements around the inner pane.
  • the insertion of the inner pane into the groove of the spacer arrangement is facilitated if the adhesive is arranged on the bottom surface of the groove.
  • the adhesive can also be applied to the edge of the inner pane and then inserted into the groove together with the inner pane so that it is arranged on the bottom surface of the groove when the inner pane is inserted. This also allows the inner disk to be inserted into the groove without problems.
  • the inner pane can be glued to a side flank of the groove.
  • the adhesive is either on the side flank of the groove or on an area of the Inner pane, which adjoins the edge to be inserted, applied.
  • the inner pane is then inserted into the groove and pressed against the side flank of the groove.
  • the spacers are preferably attached to the pane edges in a first step, with no direct contact between the adhesive tape and the surface to be bonded.
  • the spacers are then aligned and then pressed on, the adhesive tape coming into contact with the surface to be bonded and the arrangement being fixed. Bonding to the bottom surface of the groove is particularly suitable in this regard, since in this case the spacer can be loosely attached to the edge of the pane and aligned very well without being fixed early by the adhesive tape.
  • the spacer arrangement is provided as a first base body element with the first disk contact surface and a second base body element with the second disk contact surface.
  • the first main body element and the second main body element are fastened, preferably glued, to the inner pane in such a way that the groove is formed between the first main body element and the second main body element and the inner pane is inserted into the groove.
  • the base body elements can be designed identically, so that only one base body configuration has to be produced and no errors can occur when the base body elements are fastened to the inner pane.
  • the manufacturing process can be simplified, since the introduction of the inner pane into the groove is simplified in that the groove is only formed when the base body elements are attached to the inner pane.
  • the inner pane is glued to the side flanks of the groove.
  • the adhesive is applied or onto the areas of the base body elements that form the side flank of the groove an area of the inner pane that adjoins the edge to be inserted. The base body elements are then pressed against the inner pane.
  • an insulation film is applied to an outer surface of the spacer arrangement facing away from the groove.
  • the insulating film can on the one hand increase the mechanical stability of the insulating glazing base body and on the other hand leads to improved tightness and increases the insulating capacity.
  • the insulation film preferably comprises at least one polymer layer and a metallic layer or a ceramic layer.
  • the layer thickness of the polymer layer is preferably between 5 ⁇ m and 80 ⁇ m, while metallic layers and / or ceramic layers are preferably used with a thickness of 10 nm to 200 nm. A particularly good tightness of the insulation film is achieved within the specified layer thicknesses.
  • the insulation film particularly preferably contains at least two metallic layers and / or ceramic layers which are arranged alternating with at least one polymer layer.
  • the outer layers are preferably formed by the polymer layer.
  • the alternating layers of the insulation film can be connected or applied to one another using a wide variety of methods known from the prior art. Methods for depositing metallic or ceramic layers are known to the person skilled in the art.
  • the use of an insulation film with an alternating sequence of layers is particularly advantageous with regard to the tightness of the system. A fault in one of the layers does not lead to a loss of function of the insulation film. In comparison, even a small defect in a single layer can lead to complete failure.
  • the application of several thin layers is advantageous compared to one thick layer, since the greater the layer thickness, the greater the risk of internal adhesion problems.
  • thicker layers have a higher conductivity, so that such a film is less suitable thermodynamically.
  • the polymeric layer preferably comprises polyethylene terephthalate, ethylene vinyl alcohol, polyvinylidene chloride, polyamides, polyethylene, polypropylene, silicones, acrylonitriles, polyacrylates, polymethyl acrylates and / or copolymers or mixtures thereof.
  • the metallic layer preferably contains iron, aluminum, silver, copper, gold, chromium and / or alloys or mixtures thereof.
  • the ceramic layer preferably contains silicon oxides and / or silicon nitrides.
  • the insulation film preferably has a gas permeation of less than 0.001 g / (m 2 h). It is further preferred that the insulation film is designed as an adhesive film and has a self-adhesive adhesive layer on the side facing the frame. This can further increase the mechanical stability of the frame.
  • the spacers can include a wide variety of materials known to those skilled in the art, for example metals such as aluminum, rigid polymers or flexible polymers such as thermoplastic elastomers. Spacers with a rigid polymeric base body are preferably used, since these have a reduced thermal conductivity compared to metals and thus reduce the heat transfer.
  • the polymer base preferably contains polyethylene (PE), polycarbonate (PC), polypropylene (PP), polystyrene, polybutadiene, polynitrile, polyester, polyurethane, polymethyl methacrylate, polyacrylate, polyamide, polyethylene terephthalate (PET), polybutylene terephthalate (PBT), preferably acrylonitrile butadiene -Styrene (ABS), acrylic ester-styrene-acrylonitrile (ASA), acrylonitrile-butadiene-styrene / polycarbonate (ABS / PC), styrene-acrylonitrile (SAN), PET / PC, PBT / PC and / or copolymers or mixtures thereof. Particularly good results are achieved with these materials.
  • the polymer base body is preferably reinforced with glass fibers.
  • the base body preferably has a glass fiber content of 20% to 50%, particularly preferably 30% to 40%. The glass fiber content in the polymer base body improves strength and stability at the same time.
  • the polymeric base body is filled with hollow glass spheres or glass bubbles.
  • These hollow glass spheres have a diameter of 10 ⁇ m to 20 ⁇ m and improve the stability of the polymeric hollow profile. Suitable glass spheres are commercially available under the name "3M TM Glass Bubbles".
  • the polymer base body particularly preferably contains polymers, glass fibers and glass spheres. An admixture of glass spheres leads to an improvement in the thermal properties of the hollow profile.
  • the spacers have a polymeric base body.
  • polymeric base body This is advantageous in terms of reduced Thermal conductivity of polymer materials.
  • polymer materials have a lower gas tightness than, for example, metals, so that additional measures for sealing have to be provided.
  • spacers with a polymeric base body are used which are already provided with an insulating film that is glued on or coextruded with the base body. In this way, a high level of gas tightness can be achieved and in the method according to the invention, an insulation film is attached as an adhesive film, for example for sealing, on the outer surface of the corner regions of the frame.
  • the polymer base body can be used without an insulation film and, in the method according to the invention, an insulation film can be applied to the entire outer surface of the frame.
  • the spacers comprise metallic base bodies, preferably consisting of aluminum. These have a very high level of gas tightness, so that an additional seal is only required in the corner areas.
  • an insulation film in the form of an adhesive film is preferably applied to the corner areas for corner sealing.
  • An insulating film as an adhesive film has a double function as a seal against gas penetration on the one hand and as a means for mechanical stabilization on the other. Both measures are optional.
  • the use of the insulation film is dependent on the material of the base body with regard to sealing and, with regard to mechanical stabilization, on the frame size of the base body of the insulating glazing unit. Due to the high demands of today's insulating glazing in terms of tightness and insulation properties, polymeric base bodies with an insulation film that has already been applied in advance are used, with the corner areas of the frame being sealed with an insulation film as an adhesive film. With regard to the mechanical stabilization, the insulating film is generally not required as an adhesive film for fixing the corner areas, since the adhesive bond in the groove already results in a high level of stability. However, this can be helpful as an additional measure, especially with very large frame sizes.
  • the spacer arrangement has hollow chambers, which are preferably arranged between the groove and the disk contact surfaces and are filled with a desiccant.
  • Silica gels, molecular sieves, CaCl 2 , Na 2 SO 4 , activated carbon, silicates, bentonites, zeolites and / or mixtures thereof are preferably used as drying agents.
  • the insulation film can be applied to the entire outer surface of the spacer arrangement or only cover parts of the outer surface of the spacer arrangement.
  • the spacer arrangement can also be provided with a previously applied insulation film. If a configuration is formed in which several spacer arrangements are assembled to form a frame, it is particularly preferred that the insulation film is applied to corner areas of the frame in such a way that a continuous piece of the insulation film spans a corner at which two spacer arrangements contact and one Area of the outer surfaces of both spacer arrangements covered, each of which adjoins the corner.
  • an insulating film is applied as an adhesive film not only to the outer surface of the frame, but also at least to a sub-area of the pane contact surfaces adjacent to the outer surface.
  • the insulation film covers at least the area of the open end face, a region of the adjoining outer face of the adjacent spacer and a partial region of the pane contact surfaces.
  • the insulation film preferably protrudes onto the pane contact surfaces to the same extent as an insulation film already provided with the spacer profile. In this way, the gaps located between the second end surfaces and the adjacent glazing interior surface of the adjacent spacer are also closed in a gas-tight manner.
  • the insulation film is preferably used in the form of an adhesive tape with an adhesive layer, for example in the form of rolls of the appropriate width.
  • the width is dependent on the width of the spacers and should preferably exceed this in such a way that the adhesive tape protrudes proportionally to both pane contact surfaces.
  • the insulating film as an adhesive film is continuously rolled off a roll and pressed onto the outer surface of the spacer in the corner areas. Since the width of the adhesive tape exceeds the width of the spacer, the adhesive tape protrudes laterally beyond the spacer.
  • the adhesive tape is preferably centered in such a way that there is approximately the same lateral protrusion of the adhesive tape on both pane contact surfaces. After the adhesive tape has been passed around the corner of the frame and also adhered to the outer surface there, the window contact areas should be glued.
  • an incision is made in the adhesive tape on both lateral protrusions in the area of the corner bracket performed. This cut runs essentially perpendicular to the pane contact surfaces of the spacers and separates the adhesive tape at adjacent edges of the frame in the area of the lateral overhang of the adhesive tape. As a result, the adhesive tape can be folded over on the pane contact surfaces without wrinkling in the corner area.
  • the edge of the inner pane is covered with a non-transparent covering means before it is inserted into the groove of the spacer arrangement, or a covering means is inserted into the groove before the inner pane is inserted.
  • the inner panes used for the production of the insulating glazing base are usually not ground at the edges, but only cut. This can lead to reflections at the cut edges when the incidence of light is inclined, which causes an undesirable optical effect. This effect can be suppressed if the edges are provided with a non-transparent, in particular dark or black, covering agent.
  • black adhesive tape for example PVC adhesive tape or fabric tape, for example made of PET fleece, can be used as the covering means.
  • the adhesive is formed by a double-sided adhesive tape, in particular a double-sided foam adhesive tape, which is arranged on the bottom surface of the groove.
  • the double-sided adhesive tape forms the covering means and suppresses the undesired optical effects.
  • At least a section of one of the grooves of the insulating glazing base body is preferably designed to be gas-permeable.
  • the glazing interiors of the insulating glazing are designed as communicating spaces between panes. This is advantageous in terms of pressure equalization and the associated reduction in stresses in the edge seal of the insulating glazing.
  • a gas-permeable area of the groove can be created, for example, in that the groove in this section does not include an insert in the form of a covering means (or other sealing materials) or a porous insert and / or by the adhesive tape or the adhesive in the groove over a length of a few Millimeters is recessed along the groove.

  • the insulation film 13 is preferably self-adhesive.
  • the insulating film 13 effects, on the one hand, a mechanical stabilization of the frame R and a mechanical connection of the spacer arrangements I; on the other hand, it fulfills a barrier function and creates a gas- and moisture-tight seal for the insulating glazing base.
  • the width of the insulating film 13 corresponds to the width of the outer surfaces 4 of the spacer arrangements I.
  • the width of the insulating film 13 is selected to be greater than the width of the outer surfaces 4, so that the insulating film 13 after being applied to the frame R over the outer sides 4 of the spacer arrangements I. survives.
  • the insulation film 13 can then be folded over onto the pane contact surfaces 2.1 and 2.2 and cover them entirely or partially. In this case, the insulation film 13 is preferably cut at the corners of the frame R before it is folded over onto the pane contact surfaces 2.1 and 2.2 in order to avoid bulging at the corners.
  • the insulation film 13 can, as in Fig. 6 indicated, are applied to the entire outer surface of the frame R, which is formed from the outer surfaces 4 of the spacer arrangements I.
  • the insulation film 13 can be applied in such a way that it only covers parts of the outer surfaces 4 of the spacer arrangements I. It is particularly preferred here that the insulation film 13 is applied to corner areas of the frame R in such a way that a continuous piece of the insulation film 13 spans a corner at which two spacer arrangements I contact and covers an area of the outer surfaces 4 of the two spacer arrangements I, which is adjacent to the corner. This is already sufficient to ensure the mechanical stability of the To improve the frame R and thus also the stability of the insulating glazing base body formed in this way.
