Description

[0001] Composite profile and this comprehensive window or door frame

[0002] The invention relates to a composite profile for producing frames for windows or doors, comprising an inner profile and a weather-side outer wall reinforcement attached to the outside of the weather-side outer wall of the inner profile. Furthermore, the present invention relates to a window or door frame formed from sections of such a composite profile.

[0003] For window and door profiles used to frame glass panes, the aim is to achieve the best possible thermal insulation for the resulting window or door. To ensure the mechanical stability required for such windows or doors, corresponding window or door profiles made of unreinforced, thermoplastic material, such as polyvinyl chloride (PVC), require a reinforcing profile, usually metallic, to be incorporated into at least one of the hollow chambers of the window or door hollow chamber profile. This improves mechanical stability at the expense of significantly impaired thermal insulation properties. To increase stability while maintaining good thermal insulation properties, for example, DE 82 02 221 U1 discloses a profile strip consisting of a core profile made of polyvinyl chloride containing short glass fibers with a length of up to 12 mm in an amount of up to 50 wt.%, and a PVC sheath profile with high impact resistance encasing this core profile.A disadvantage of the profile strip described in DE 82 02 221 U1 is that the elastic moduli achievable in this way are insufficient for a completely steel-free construction of window and door elements of all sizes and for other requirements placed on window and door profile hollow chamber profiles with regard to wind load, weight load, and thermal load. Furthermore, EP 4 174 272 A1 discloses a composite profile for producing frames for windows or doors, which comprises a plastic hollow profile with multiple hollow chambers and a metal outer wall reinforcement fastened to the weather-facing outer wall of the plastic hollow profile, wherein at least one inner reinforcement made of a reinforced plastic is firmly attached to the inner side of the room-facing outer wall facing the profile interior.However, metals as materials for exterior wall reinforcement exhibit high thermal conductivities, which makes them only suitable to a limited extent for energy-efficient construction. Furthermore, in order to recycle the composite profile described in EP 4 174 272 A1, the exterior wall reinforcement must first be separated from the plastic hollow profile. This is where the present invention comes in, which is based on the object of providing a composite profile for producing frames for windows or doors that at least partially overcomes the disadvantages of the prior art. In particular, the composite profile according to the invention should have high mechanical stability. Furthermore, the composite profile according to the invention should have good thermal insulation properties. Ultimately, the present invention also lies in the provision of a window or door frame formed from sections of a composite profile according to the invention.

[0004] These and other objects are achieved according to the invention by a composite profile for producing frames for windows or doors having the features of claim 1 or by a window or door frame having the features of claim 12. Preferred embodiments of the composite profile according to the invention and of the window or door frame according to the invention are each described in the dependent claims.

[0005] According to the present invention, it was discovered that a weather-side exterior wall reinforcement made of a plastic material and containing reinforcing fibers can be used to obtain composite profiles for the production of window or door frames that meet the requirements for window and door profiles with regard to wind load, weight load, and thermal load. Finally, a composite profile with such a weather-side exterior wall reinforcement is also easy to recycle because the exterior wall reinforcement does not need to be removed prior to recycling.

[0006] Accordingly, the present invention provides a composite profile for producing frames for windows or doors, comprising (a) an inner profile and (b) a weather-side outer wall reinforcement attached to the outside of the weather-side outer wall of the inner profile, wherein the composite profile is characterized according to the invention in that the weather-side outer wall reinforcement is formed as a reinforcing profile made of a plastic matrix and reinforcing fibers embedded in the plastic matrix. Furthermore, the present invention provides a window or door frame formed from sections of a composite profile according to the invention. As used herein, the term "plastic material" means a plastic to which the additives customary for the (co-)extrusion or pultrusion of window or door profile hollow chamber profiles, such as stabilizers, plasticizers, pigments, and the like, have been added.Accordingly, the term “polyamide material,” as used herein, means a polyamide to which the additives customary for the (co-)extrusion or pultrusion of window or door profile hollow chamber profiles, such as stabilizers, plasticizers, pigments, and the like, have been added. The same applies accordingly to polyolefins, polyvinyl chloride (PVC), poly(meth)acrylates, polyesters, and the like. Furthermore, the term “weather-side exterior wall,” as used herein, describes the wall of the composite profile according to the invention which, when the window or door frame according to the invention is used as intended, faces the outside of the building. Accordingly, the term “room-side exterior wall” (the side opposite the weather side), as used herein, describes the wall of the composite profile according to the invention which, when the window or door frame according to the invention is used as intended, faces the room side of the window or door.of the door, which comprises the window or door profile hollow chamber profile according to the invention. Likewise, the "weather-side exterior wall reinforcement" is arranged on the weather-side exterior wall, while the "room-side exterior wall reinforcement" is arranged on the room-side exterior wall of the interior profile.

[0007] With regard to the composite profile according to the invention, it is helpful if the inner profile is designed as a hollow plastic profile with multiple hollow chambers, as an aluminum profile, a thermally separated aluminum profile, or as a wooden profile. A hollow plastic profile with multiple hollow chambers is particularly preferred. With a hollow plastic profile with multiple hollow chambers, the reinforcing effect of the weather-side outer wall reinforcement is particularly strong. Furthermore, such a composite profile according to the invention is particularly easy to recycle. A polyvinyl chloride material, in particular a fiber-reinforced polyvinyl chloride material, is preferably used for the inner profile. In the case of a wooden profile, the side of the wooden profile exposed to the weather can be protected from the effects of the weather by using a weather-side outer wall reinforcement.

[0008] It may also be advantageous if the composite profile further comprises a room-side outer wall reinforcement attached to the outside of the room-side outer wall of the inner profile. An additional room-side outer wall reinforcement further increases the mechanical stability of the composite profile according to the invention.

[0009] In preferred embodiments of the composite profile according to the invention, the plastic matrix of the weather-side exterior wall reinforcement and / or the interior-side exterior wall reinforcement is formed from a polyamide material, a polyvinyl chloride material, a poly(meth)acrylate material, a polyester material, or a copolymer or blend of the materials mentioned. The plastic matrix of the weather-side exterior wall reinforcement and / or the interior-side exterior wall reinforcement is expediently designed as a polyacrylate matrix, in particular a PMMA matrix. In this case, the weather-side exterior wall reinforcement and / or the interior-side exterior wall reinforcement is preferably produced by reactive pultrusion of the corresponding monomers and / or reactive oligomers to produce polyacrylate, e.g., polymethyl methacrylate (PMMA). The production of other materials by means of reactive pultrusion, for example, polyester, e.g.,However, this does not exclude the use of polyethylene terephthalate (PET), in particular impact-resistant polyethylene terephthalate (PET-G), or polybutylene terephthalate (PBT), or thermoplastic polyurethanes (TPU). The production of polyamide, for example PA6 or PA12, or bisphenol A (BPA), polycarbonate (PC), polyesteramides or polyimides, preferably by means of reactive pultrusion, is also within the scope of the invention. If the plastic matrix of the weather-side exterior wall reinforcement and / or the room-side exterior wall reinforcement comprises a polyamide, the polyamide is preferably selected from the group comprising polyamide 6 (PA 6), polyamide 6.6 (PA 6.6), polyamide 6.10 (PA 6.10), polyamide 4.6 (PA 4.6), polyamide 12 (PA 12) as well as copolyamides and blends of the aforementioned polyamides. Polyamide 6 is particularly preferred due to its good availability.With regard to reactive pultrusion and the production of window and door profile hollow chamber profiles by means of reactive pultrusion, reference is made to WO 2018 / 072828 766 A1, to which explicit reference is hereby made.

[0010] It may also be advantageous if the weather-side exterior wall reinforcement and / or the room-side exterior wall reinforcement are integrally bonded to the inner profile, in particular glued or welded. If the inner profile of the composite profile according to the invention is a hollow plastic profile with multiple hollow chambers, the window formed from the composite profile according to the invention no longer requires the weather-side exterior wall and / or the room-side exterior wall to be separated when recycling. All materials of the composite profile according to the invention are thermoplastic and can therefore be recycled together.

[0011] Alternatively or additionally, it may also prove advantageous if the weather-side exterior wall reinforcement and / or the room-side exterior wall reinforcement comprise at least one locking element that engages with a fastening groove of the inner profile. In this way, the exterior wall reinforcements can be easily and securely connected to the inner profile. It is preferred if the weather-side exterior wall reinforcement and the room-side exterior wall reinforcement each comprise a locking element that engages with a corresponding fastening groove of the inner profile. At the same time, the inner profile can also have at least one corresponding locking element that then engages with a corresponding fastening groove of the respective exterior wall reinforcement.In all cases, the weather-side exterior wall reinforcement and / or the room-side exterior wall reinforcement can additionally be materially connected to the inner profile, in particular by welding or by gluing, preferably by gluing.

[0012] It can also be advantageous if the weather-side exterior wall reinforcement and / or the room-side exterior wall reinforcement comprise / comprise a core profile made of a plastic material and a jacket profile that at least partially encloses the core profile and is made of a thermoplastic material compatible with the plastic material of the core profile. It is particularly preferred if the weather-side exterior wall of the weather-side exterior wall reinforcement and / or the room-side exterior wall of the room-side exterior wall reinforcement are formed by the jacket profile, at least on their surface facing away from the core profile. As a result, the visible surfaces of the structural elements formed from the composite profile according to the invention, i.e., corresponding windows or doors, are formed from the jacket profile, whereby the core profile, which may be superficially rough due to the fibers it contains, is concealed from the outside by the jacket profile.It is particularly preferred if the weather-side outer wall of the weather-side outer wall reinforcement and / or the room-side outer wall of the room-side outer wall reinforcement are formed from a preferably 0.3 mm to 1.5 mm thick layer of the casing profile. The remaining wall thickness of the weather-side outer wall and / or the room-side outer wall can be formed by the core profile. As a result, smooth visible surfaces of the components formed from the window or door profile hollow chamber profile according to the invention are retained while the formed frame is very stable. The cover layer formed by the casing profile preferably has a thickness in the range from approximately 0.4 mm to approximately 1.2 mm, in particular approximately 0.5 mm to approximately 0.9 mm, particularly preferably approximately 0.6 mm. The casing profile preferably does not comprise any reinforcing fibers.

[0013] It can also be useful if the plastic material of the core profile is a polyamide material and the thermoplastic material of the shell profile, compatible with the plastic material of the core profile, is a blend of a polyamide material and an acrylonitrile-styrene-acrylate terpolymer (ASA). Particularly preferably, the polyamide of the core profile is selected from the group comprising polyamide 6 (PA 6), polyamide 6.6 (PA 6.6), polyamide 6.10 (PA 6.10), polyamide 4.6 (PA 4.6), polyamide 12 (PA 12), and blends of the aforementioned polyamides. Polyamide 6 is particularly preferred due to its good availability. The thermoplastic material of the casing profile that is compatible with the plastic material of the core profile is also preferably selected from the group comprising polyamide 6 (PA 6), polyamide 6.6 (PA 6.6), polyamide 6.10 (PA 6.10), polyamide 4.6 (PA 4.6), polyamide 12 (PA 12), and blends of the aforementioned polyamides with each other and with other polymers or copolymers, in particular acrylonitrile-butadiene-styrene terpolymers (ABS) and acrylonitrile-acrylate-styrene terpolymers (ASA), with blends of the polyamides with an acrylonitrile-acrylate-styrene terpolymer (ASA) being preferred due to their good weather resistance. Preferably, the polyamide of the core profile is also used as the thermoplastic material of the casing profile. In particularly preferred embodiments of the hollow chamber window or door profile according to the invention, polyamide 6 is used as the polyamide of the core profile, and a blend of polyamide 6 and an acrylonitrile-acrylate-styrene terpolymer is used as the thermoplastic material of the casing profile.

[0014] It can also be helpful if the weather-side exterior wall reinforcement and / or the room-side exterior wall reinforcement comprise(s) a core profile made of a plastic material and a shell profile that at least partially encloses the core profile, wherein the shell profile is designed as a powder coating. A corresponding powder coating ensures good weather resistance of the composite profile according to the invention. A particularly well-adhering powder coating is obtained if the core profile is designed to be electrically conductive or statically conductive, at least on its surface. It has proven sufficient if the surface resistance of the core profile according to DIN EN 62631-3-2:2016-10 is at most 10 8 Q is, preferably, at most 10 6Q. This can preferably be achieved by the plastic material of the core profile or an outer layer of the core profile containing electrically conductive particles in a proportion of 10 wt.% to 60 wt.%, based on the weight of the core profile as 100 wt.%. Electrically conductive particles can be metallic (copper, aluminum, and the like) or organic (graphite, carbon black, graphene, and the like). As an alternative to pigmentary fillers, electrically conductive fibers can be used (for example, carbon fibers or metal wires, and the like).

[0015] The reinforcing fibers are expediently formed as glass fibers and / or carbon fibers and / or aramid fibers and / or basalt fibers, although other fiber materials are not excluded. According to the invention, however, the use of glass fibers as reinforcing fibers contained in the plastic matrix is ​​preferred. Within the scope of the invention, it is preferred to use short glass fibers with a fiber length in the range from 0.1 mm to 5 mm, long glass fibers with a fiber length in the range from 5 mm to 50 mm and / or continuous glass fibers with a length of more than 50 mm, individually or in combination. While when using short and long glass fibers, the weather-side external wall reinforcement and / or the room-side external wall reinforcement is preferably produced by extrusion oris / are produced by coextrusion, the production of the weather-side external wall reinforcement and / or the room-side external wall reinforcement by means of reactive pultrusion is most suitable when using continuous glass fibers. When using short glass fibers, it can also be advantageous if the average fiber length of the reinforcing fibers is in the range of 1.5 mm to 3.2 mm. An average length of the glass fibers in this range leads to high mechanical stability of a composite profile according to the invention, both in the longitudinal direction and perpendicular to it. In this context, an average fiber length in a range of 2.5 mm to 3.0 has proven to be particularly suitable. According to the invention, the use of continuous glass fibers is particularly preferred. Using continuous glass fibers, the highest stiffness and strength values ​​are achieved with an E-modulus according to DIN EN ISO 527-4: 2022-03 of up to 70,000 N / mm. 2 in the profile longitudinal direction.

[0016] It may be preferred if the reinforcing fibers are contained in the weather-side exterior wall reinforcement and / or the room-side exterior wall reinforcement in a proportion of 20 wt.% to 80 wt.%, based on the weight of the respective exterior wall reinforcement. If the weight fraction of the reinforcing fibers in the core profile is within the range of 20 wt.% to 80 wt.%, based on the weight of the respective exterior wall reinforcement, excellent elastic moduli are achieved according to DIN EN ISO 527-4: 2022-03. In this context, it is preferred if the weight fraction of the reinforcing fibers in the core profile is within the range of 25 wt.% to 60 wt.%, based on the weight of the core profile.

[0017] It may also be advantageous if the composite profile according to the invention has an E-modulus according to DIN EN ISO 527-4: 2022-03 in the range of 7000 N / mm 2 up to 70000 N / mm 2in the longitudinal direction of the profile.

[0018] All plastic materials in the composite profile according to the invention can also be used in the form of materials obtained through a recycling process. In particular, it is preferred that a recycled polyamide be contained in the inner profile. Additionally or alternatively, "fresh," i.e., non-recycled, polymer material can also be used in the outer profile.

[0019] The weather-facing exterior wall of the weather-facing exterior wall reinforcement and / or the room-facing exterior wall of the room-facing exterior wall reinforcement can preferably be dark-colored and / or coated with a dark film, paint, or coating and / or co-extruded with a dark layer. Due to the high mechanical stability of the exterior wall reinforcements, the problem of profile deformation at high temperatures in dark exterior walls can be well compensated. As used herein, the term "dark" means that the dark color absorbs more than 50%, preferably more than 60%, of the vertically incident sunlight, including the relevant IR range.

[0020] Particularly preferably, the weather-side external wall reinforcement and the room-side external wall reinforcement can be produced in a manner known per se by (co)extrusion of the core profile and the shell profile.

[0021] The statements regarding the composite profile according to the invention apply accordingly to the window or door frame according to the invention. To produce a window or door frame according to the invention, the composite profile according to the invention is mitered, and mitered sections are connected to form a frame in a conventional manner using corner connectors or welded corner connectors. Alternatively, it is also possible to mill back the weather-side exterior wall reinforcement and / or the interior-side exterior wall reinforcement a certain distance and weld the mitered surfaces of the interior profiles together to form a window or door frame according to the invention.

[0022] The window or door frame according to the invention, the composite profile according to the invention and individual parts thereof can also be produced line by line or layer by layer using a line-building or layer-building manufacturing process (e.g. 3D printing), but production by (co-)extrusion (including pultrusion) is preferred.

[0023] In the following, the present invention will be explained in detail with reference to the embodiments shown in the figures.

[0024] Figure 1 is a cross-sectional view of a composite profile designed as a window sash profile according to an embodiment of the present invention; and

[0025] Figure 2 is a cross-sectional view of a composite profile also designed as a window sash profile according to a further embodiment of the present invention.

[0026] Figure 1 shows an embodiment of the composite profile 100 according to the invention using the example of a sash profile for a composite window in a cross-sectional view. The composite profile 1 according to the invention comprises: According to the invention, the composite profile for producing frames for windows or doors comprises an inner profile 10 and a weather-side outer wall reinforcement 30 fastened to the outside of the weather-side outer wall 20 of the inner profile 10. Furthermore, the composite profile 100 according to the invention also comprises a room-side outer wall reinforcement 35, which is fastened to the outside of the room-side outer wall 25 of the inner profile 10. According to the embodiment shown in Fig. 1, the inner profile 10 is designed as a hollow plastic profile 10 with a plurality of hollow chambers 60, wherein rigid PVC (PVC-II) with appropriate additives is used as the plastic material of the inner profile 10.Centrally, the inner profile 10 has a main hollow chamber 61 or reinforcement chamber, into which a reinforcement element, in particular a corresponding steel reinforcement, can be accommodated, which, if necessary, further increases the mechanical stability of a window or door frame formed from the composite profile 100 according to the invention. However, the mechanical stability of the composite profile 100 according to the invention alone, i.e., without an additional reinforcement element, is sufficient for forming large window or door frames.

[0027] Furthermore, in the embodiment of the composite profile 100 according to the invention shown in Fig. 1, the plastic matrix of both the weather-side exterior wall reinforcement 30 and the room-side exterior wall reinforcement 35 is formed by reactive pultrusion from a polyamide material into which continuous glass fibers are embedded by the pultrusion in a weight proportion of 60 wt.%, based on the total weight of the respective exterior wall reinforcement 30, 35. In this embodiment, polyamide 6 is used.

[0028] To attach the exterior wall reinforcements 30, 35 to the inner profile 10, the weather-side exterior wall reinforcement 30 has two locking elements 32, 34 that engage in corresponding fastening grooves on the weather-side exterior wall 11 of the inner profile 10. In contrast, the room-side exterior wall reinforcement 35 has a locking element 36 that engages in a fastening groove on the room-side exterior wall 21 of the inner profile 10. In addition, the inner profile 10 comprises a further locking element 22 on its room-side exterior wall 21, which engages in a corresponding fastening groove on the room-side exterior wall reinforcement 35.

[0029] Through the respective fastening, an additional hollow chamber 62, 63 is formed between the weather-side outer wall reinforcement 30 and the weather-side outer wall 11 of the inner profile 10, as well as between the room-side outer wall reinforcement 35 and the room-side outer wall 21 of the inner profile 10, which further improves the thermal insulation properties of the composite profile 100 according to the invention. Thus, the inner profile 10, the weather-side outer wall reinforcement 30, and the room-side outer wall reinforcement 35 are each open profiles. Fig. 2 shows a further embodiment of the composite profile 100 according to the invention. To avoid repetition, only differences from the embodiment of the composite profile 100 shown in Fig. 1 are described below. The embodiments of Fig. 1 also apply accordingly to the embodiment according to Fig. 2.Identical elements are identified by identical reference numerals in the figures.

[0030] Fig. 2 shows a further embodiment of the composite profile 100 according to the invention, also using the example of a sash profile for a plastic window, in a cross-sectional view. The embodiment shown in Fig. 2 differs from the embodiment described in Fig. 1 primarily with regard to the attachment of the weather-side exterior wall reinforcement 30 and the room-side exterior wall reinforcement 35 to the inner profile 10, which is achieved in each case by bonding with a suitable liquid adhesive.

[0031] For this purpose, the walls of the weather-side exterior wall reinforcement 30 and the room-side exterior wall reinforcement 35 facing the inner profile 10 are smooth. Likewise, the weather-side exterior wall 11 and the room-side exterior wall 21 are smooth, so that a large adhesive surface is available between the inner profile and the exterior wall reinforcements 30, 35.

[0032] Alternatively, the weather-side outer wall 11 of the inner profile 10 can be welded to the weather-side outer wall reinforcement 30, and the room-side outer wall 21 can be welded to the room-side outer wall reinforcement 35. Large areas for welding are also available for these.

[0033] To improve the thermal insulation properties of the composite profile 100 according to the invention, both the weather-side outer wall reinforcement 30 and the room-side outer wall reinforcement 35 each have an additional hollow chamber 62, 63. In the embodiment of the composite profile 100 according to the invention shown in Fig. 2, the inner profile 10, the weather-side outer wall reinforcement 30, and the room-side outer wall reinforcement 35 are each closed profiles.

[0034] The present invention has been described by way of example with reference to composite profiles for the sash of a window with an inner profile designed as a plastic hollow chamber profile. It is understood that the present invention is also applicable to other window or door profiles, in particular post profiles, window frame profiles, and door frame, casing, or sash profiles, even with other profile types as the inner profile.
