Definitions
- the invention relates to a spacer for insulating glass units, an insulating glass unit, a method for producing an insulating glass unit and their use.
- Insulating glazing usually contains at least two glass or polymeric materials.
- the disks are separated from each other by a gas or vacuum space defined by the spacer.
- the thermal insulation capacity of insulating glass is significantly higher than that of single glass and can be further increased and improved in triple glazing or with special coatings.
- Silver-containing coatings for example, enable a reduced transmission of infrared radiation and thus reduce the cooling of a building in winter.
- the contact points between the spacer and the glass pane are very susceptible to temperature and climatic fluctuations.
- the connection between the disc and the spacer is produced via an adhesive bond of organic polymer, for example polyisobutylene.
- organic polymer for example polyisobutylene.
- the glass and the spacers have different coefficients of thermal expansion, that is, they expand
- the heat-insulating properties of insulating glazings are significantly influenced by the thermal conductivity in the region of the edge bond, in particular of the spacer.
- the high thermal conductivity of the metal results in the formation of a thermal bridge at the edge of the glass.
- this thermal bridge leads to heat losses in the edge region of the insulating glazing and, on the other hand, in the case of high air humidity and low outside temperatures, the formation of condensate on the inner pane in the area of the spacer.
- so-called "warm-edge" systems are used, in which the spacers consist of materials with lower thermal conductivity, in particular plastics.
- polymeric spacers are preferable to metallic spacers.
- polymeric spacers have several disadvantages. On the one hand, the tightness of the polymeric spacers against moisture and gas loss is not sufficient.
- a barrier film on the outside of the spacer see for example WO2013 / 104507 A1.
- the coefficients of linear expansion of plastics are much larger than those of glass.
- glass fibers can be admixed (see, for example, EP0852280 A1).
- an increased glass fiber content deteriorates the heat-conducting properties of the spacer, so that a precise optimization must be carried out here.
- Glass fibers and similar fillers also improve the longitudinal rigidity of the spacer.
- Polymer glass fiber reinforced spacers are so brittle that unlike metallic spacers they are not cold bendable.
- For the manufacture of a spacer frame for an insulating glass unit several pieces of spacers must be connected via connectors and glued or welded. Each joint must be carefully sealed. Therefore, the production of a spacer frame by bending is advantageous. In particular, bending without additional heating is desirable for ease of machinability.
- One approach to increasing bendability is to integrate one metallic strip in the polymeric body (for example, in WO2015 / 043848 A1 and DE19807454 A1 described). However, the integration of a metallic strip into the polymeric base body is very complicated during production.
- Polymeric spacers without additional fillers such as glass fibers are flexible and not sufficiently rigid.
- the longitudinal stiffness refers to longitudinal deflection
- An improvement in the longitudinal stiffness can be achieved by the integration of metallic strips (see previous point) or the external application of metallic elements on the body (see for example EP1055046B2 and EP3241972 A1).
- the application of a metallic strip deteriorates the heat-conducting properties of the spacer, since the metallic elements have an increased thermal conductivity.
- a particular difficulty in the external application of individual metallic elements is the perfect sealing of the edge compound against the ingress of moisture.
- the spacer according to the invention for insulating glass units comprises at least one polymeric hollow profile with a first side wall, one arranged parallel thereto second side wall, a glazing interior wall, an exterior wall and a cavity.
- the cavity is enclosed by the side walls, the glazing interior wall and the exterior wall.
- the glazing interior wall is arranged substantially perpendicular to the side walls and connects the first side wall with the second side wall.
- the side walls are the walls of the hollow profile to which the outer panes of the insulating glass unit are attached.
- the glazing interior wall is the wall of the hollow profile, which points to the inner space between the panes after installation in the finished insulating glass unit.
- the outer wall is arranged substantially parallel to the glazing interior wall and connects the first side wall to the second side wall. The outer wall has after installation in the finished insulating glass unit to the outer space between the panes.
- the spacer further comprises two metallic reinforcing elements which are externally attached to the polymeric hollow profile.
- the metallic reinforcing elements improve the longitudinal rigidity of the spacer and achieve an approximation of the coefficient of linear expansion of the spacer to that of the glass in an insulating glass unit.
- the first reinforcing element surrounds the corner between the first side wall and the outer wall and is mounted there in a recess provided in the wall of the polymeric hollow profile.
- the second reinforcing element surrounds the corner between the second side wall and the outer wall and is mounted there in a recess provided in the wall of the polymeric hollow profile.
- the reinforcing elements are mounted in the recesses so that they are flush with the side walls and the outer wall.
- the gas- and moisture-proof barrier film is applied to the first side wall, the first metal reinforcing element, the outer wall, the second metal reinforcing element and on the second side wall of the polymeric hollow body.
- the gas- and moisture-proof barrier film seals the inner pane cavity against the ingress of moisture and prevents the loss of a gas contained in the inner space between the panes.
- the barrier film is applied so that the adjacent to the glazing interior wall areas of the two side walls are free of barrier film.
- the primary sealant can be applied so that it extends over the barrier film and over a portion of the polymeric sidewall. This achieves a uniform sealing level and achieves a particularly good seal.
- the spacer according to the invention provides an improved solution over the prior art.
- the cavity of the spacer according to the invention leads to a reduction in weight compared to a solid-shaped spacer and is available for receiving other components, such as a desiccant available.
- the first side wall and the second side wall represent the sides of the spacer at which the mounting of the outer panes of an insulating glass unit takes place during installation of the spacer.
- the first side wall and the second side wall are parallel to each other.
- the outer wall of the hollow profile is the wall opposite the glazing inner wall, which points away from the interior of the insulating glass unit (inner pane clearance) in the direction of the outer space between the panes.
- the outer wall preferably runs substantially perpendicular to the side walls.
- a flat outer wall that behaves perpendicular to the side walls (parallel to the glazing interior wall) in its entire course has the advantage that the sealing surface between spacers and side walls is maximized and simpler shaping facilitates the production process.
- the sections of the outer wall closest to the side walls are inclined at an angle a (alpha) of 30 ° to 60 ° to the outer wall in the direction of the side walls.
- a (alpha) of 30 ° to 60 ° to the outer wall in the direction of the side walls.
- This embodiment improves the stability of the polymeric hollow profile.
- the stability of the spacer is increased because the metallic reinforcing elements are particularly stable thanks to the double-angled design. It is thus possible to reduce the wall thickness d of the polymeric hollow profile compared to a shape without angled sections. A reduction in the wall thickness in turn leads to improved bendability and lower material costs.
- the sections closest to the side walls are preferably inclined at an angle a (alpha) of 45 °. In this case, the stability of the spacer is further improved.
- the two metallic reinforcing elements are glued to the polymeric hollow profile.
- This embodiment is particularly easy to produce. A separate production of hollow profile and reinforcing element is possible.
- the difference in the coefficients of linear expansion of the metallic reinforcing elements and the polymeric hollow profile (metal and polymer) causes the connection between the reinforcing element and the polymer hollow profile to be subjected to stresses in the event of temperature differences.
- an adhesive layer By attaching an adhesive layer, a part of the stresses can be absorbed via the elasticity of the adhesive layer.
- Suitable adhesives are thermoplastic adhesives, but also reactive adhesives, such as multicomponent adhesives.
- a preferred adhesive is a thermoplastic Glue, particularly preferably used a thermoplastic polyurethane. This has proven to be particularly suitable in experiments.
- the hollow profile contains no glass fibers.
- the presence of glass fibers degrades the heat-insulating properties of the spacer.
- spacers with glass fibers in the hollow profile are worse cold bendable, since they are brittle.
- the presence of glass fibers is surprisingly not necessary for the adaptation of the coefficient of linear expansion of the spacer to that of the glass.
- a coefficient of linear expansion of 27 ⁇ 10 6 1 / K was measured. This means that a 1 km long spacer expands by 27 mm when the temperature rises by 1 K.
- the polymeric hollow profile has a substantially uniform wall thickness d. This leads to an improvement in the bendability in comparison to hollow profiles with regions of different wall thickness. It has been shown that with a uniform wall thickness fewer fractures of the spacer occur during cold bending than at different wall thicknesses.
- the wall thickness d is from 0.3 mm to 0.8 mm.
- the spacer is stable and at the same time flexible enough to be cold bendable.
- the wall thickness of 0.5 mm to 0.6 mm. With these wall thicknesses the best results are achieved. Deviations of 0.1 mm upwards and downwards are possible due to the production.
- the metallic reinforcing elements contain or consist of aluminum, stainless steel or steel. These Materials are easy to process and provide particularly good results when adjusting the coefficient of linear expansion. Particularly preferably, the reinforcing elements consist of a coated steel, which is preferably coated with a bonding agent. Steel has a lower thermal conductivity and good elongation compared to aluminum. In addition, steel is very stable and cheaper than stainless steel.
- the metallic reinforcing elements are attached in the form of a metallic foil or a metal sheet. These have the advantage that they provide a flat surface for the attachment of the barrier film. On the other hand, nets or grids are less easily adhered with a barrier film, but have the advantage that less material is needed for the production.
- the thickness of the first and second metallic reinforcing elements is between 0.1 mm to 0.4 mm.
- a good stiffening of the polymeric hollow profile is achieved by the reinforcing elements and at the same time the thermal conductivity in the edge region of the future insulating glass unit is only slightly increased.
- a thickness of 0.2 mm has proved particularly advantageous. Manufacturing tolerances in thickness are 0.1 mm up and down.
- the height a of the area left by the barrier film is between 1 mm and 3 mm.
- the barrier film is not visible in the finished insulating glass unit and the visual impression is thus advantageous.
- the primary sealant may be mounted in the finished insulating glazing so that the primary sealant is applied to the plastic of the sidewalls and the barrier film. Thus, interfacial diffusion at the transition from barrier film to plastic is significantly reduced.
- the first and second reinforcing elements each have legs of equal length.
- the legs are the areas that protrude on the sidewall and on the outer wall.
- the legs are the areas that are not disposed on the inclined portion of the outer wall of the hollow profile.
- the hollow profile contains polyethylene (PE), polycarbonates (PC), polypropylene (PP), polyethylene terephthalate (PET), polyethylene terephthalate glycol (PET-G), polyoxymethylene (POM), polyamides, polybutylene terephthalate (PBT).
- the hollow profile consists essentially of one of the listed polymers. These materials give particularly good results in terms of the flexibility required for the flexibility of the spacer without additional heating.
- the spacer contains exactly two metallic reinforcing elements. This reduces the material costs for further reinforcing elements and improves the heat-insulating properties.
- the spacer contains further metallic reinforcing elements. Further reinforcing elements can further improve the rigidity of the spacer.
- the spacer still contains a third reinforcing element, which is arranged in the region of the outer wall and is also contained in a recess, so that it is flush with the outer wall.
- the glazing interior wall has at least one perforation.
- a plurality of perforations are mounted in the glazing interior wall.
- the total number of perforations depends on the size of the insulating glass unit.
- the perforations in the glazing interior wall connect the cavity to the inner space between the panes, allowing gas exchange therebetween.
- a recording of humidity is allowed by a desiccant located in the cavity and thus prevents fogging of the discs.
- the perforations are preferably designed as slots, particularly preferably as slots with a width of 0.2 mm and a length of 2 mm. The slots ensure optimal air exchange without the possibility of drying agents penetrating from the cavity into the inner space between the panes.
- the perforations can be easily punched or drilled into the glazing cavity wall after the hollow profile is made. Preferably, the perforations are punched warm into the glazing interior wall. In an alternative preferred embodiment, the material of the glazing interior wall is made porous or with a diffusion-open plastic, so that no perforations are required.
- the gas-tight and moisture-proof barrier film prevents the penetration of moisture into the cavity of the spacer.
- the barrier film may be a metal foil or polymer film or a multilayer film with polymeric and metallic layers or with polymeric and ceramic layers or with polymeric, metallic and ceramic layers.
- the barrier film preferably contains at least one polymeric layer and also a metallic layer or a ceramic layer.

- the barrier film contains at least two metallic layers and / or ceramic layers, which are arranged alternately with at least one polymeric layer.
- the outer layers are preferably formed by the polymeric layer.
- the alternating layers of the barrier film can be bonded or applied to one another in a variety of methods known in the art. Methods for the deposition of metallic or ceramic layers are well known to those skilled in the art.
- the use of a barrier film with alternating layer sequence is particularly advantageous in terms of the tightness of the system. An error in one of the layers does not lead to a loss of function of the barrier film. By comparison, even a small defect in a single layer can lead to complete failure.
- the application of several thin layers in comparison to a thick layer is advantageous, since the risk of internal adhesion problems increases with increasing layer thickness.
- thicker layers have a higher conductivity, so that such a film is thermodynamically less suitable.
- the polymeric layer of the barrier film 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 oxides thereof.

- the width is the distance between the oppositely facing surfaces of the two side walls.
- the hollow profile preferably has a height of 5 mm to 15 mm along the side walls, particularly preferably of 5 mm to 10 mm.

- the primary sealing means extends to the areas of the first and second side wall which are adjacent to the glazing interior wall and which are free of the barrier film.
- the primary sealant covers the transition between the polymer hollow profile and the barrier film, so that a particularly good sealing of the insulating glass unit is achieved. In this way, the diffusion of moisture into the cavity of the spacer at the location where the barrier film borders the plastic is reduced (less interfacial diffusion).
- the secondary sealing means along the first disc and the second disc is applied so that a central region of the outer wall is free of secondary sealing means.
- the central area indicates the central area with respect to the two outer panes, as opposed to the two outer areas of the outer wall which are adjacent to the first pane and the second pane.
