Description

[0001] The invention relates to a profile arrangement for building elements, furniture panels and the like, comprising at least one melt layer and at least one structural layer connected to the melt layer, both of which comprise at least partially a polymeric material, both of which have a defined width B of approximately 10 to 120 mm, preferably 15 to 100 mm.

[0002] It is known from the prior art that profile arrangements are attached or fixed to protect the end faces of building elements, furniture panels, and the like. Hot-melt adhesives, for example, are used for this purpose, but these result in a visible gap between the profile arrangements and the building elements, furniture panels, which is visually unappealing.

[0003] EP 1 163 864 discloses a construction element, in particular a furniture panel, and a method for its production. It discloses how a profile element can be fixed to wood materials via a polymer functional layer by applying heat, for example, using laser technology. When fixing this profile element to construction elements, it is difficult to achieve a secure hold, particularly for the polymer profile element, with various materials.

[0004] Furthermore, it is known from the prior art that when applying the profile arrangements to the end faces of building elements, furniture panels and the like, the problem can arise when activating / melting the melt layer by, for example, thermal activation that the profile arrangements with their melted, partially liquid melt layer stick in the corresponding guide elements of the edge banding machines, contaminate them and are therefore difficult to transport further, so that the manufacturing process is not yet optimal.

[0005] EP 2335891 A discloses a gluing device comprising feed means for advancing an edge element along a first feed path in a feed direction; dispensing means for dispensing an adhesive substance arranged along the first feed path, the dispensing means being suitable for distributing a layer of adhesive onto an edge element extending along the first feed path in the feed direction for gluing the edge element to a respective side of a panel; control means for controlling the dispensing means; the control means enabling the adjustment of a width of the layer of adhesive.

[0006] The dispensing device comprises an opening from which the layer of adhesive substance emerges, the opening being substantially shaped as an elongated slit. The control device comprises a closure device suitable for adjusting / closing the opening.

[0007] The invention is based on the object of providing a profile arrangement for building elements, furniture panels and the like, which overcomes the disadvantages of the prior art, which can be produced economically and cost-effectively, which can be optically fixed to the end faces of building elements, furniture panels and the like with almost no parting line, which does not influence the manufacturing process of the building elements, furniture panels and the like and which has a high moisture resistance, particularly in the connection area to the end faces of the building elements, furniture panels and the like.

[0008] To achieve this object, the invention provides a profile arrangement having the features according to claim 1, as well as a building board, furniture board and the like having at least one such profile arrangement.

[0009] It has surprisingly been found that a profile arrangement for building elements, furniture panels and the like, comprising at least one melt layer and at least one structural layer connected to the melt layer, both of which at least partially comprise a polymeric material, both of which have a defined width B of approximately 10 to 120 mm, preferably 15 to 100 mm, is characterized in that the melt layer has, at least in part, a smaller width B3 than the width B2 of the structural layer on at least one longitudinal edge side L3, and that the structural layer is arranged at a distance from the longitudinal edge side L3 of the melt layer on at least one longitudinal edge side L2, at least in part.With the profile arrangement according to the invention, it is surprisingly possible to further optimize the production of building elements, furniture panels, and the like and to significantly reduce the downtime and maintenance intervals of edge banding machines that sometimes occurred in the past. A further advantage of the profile arrangement according to the invention is that, on the one hand, the corresponding edge banding machines can be designed / manufactured more simply and optimally, and, on the other hand, the manufacture or production of such building elements, furniture panels, and the like can be realized faster, easier, and with less maintenance. Another advantage of the profile arrangement according to the invention is that, on the one hand, the optimized melt layer enables optimal and joint-free fixing to the end faces of the building elements, furniture panels, and the like, and, on the other hand, material and / or energy savings can be realized in the manufacturing processes.

[0010] The melt layer on at least one longitudinal edge L3 has a width B3 that is approximately 0.2-8.5%, and according to the invention, 0.5 to 4.7%, smaller than the width B2 of the structural layer. This allows the profile arrangement according to the invention to be produced both economically and cost-effectively.

[0011] In a further advantageous embodiment of the profile arrangement according to the invention, the structural layer is arranged on at least one longitudinal edge L2 at a distance of at least 0.1 - 4.0 mm, preferably 0.15 - 2.0 mm, from the longitudinal edge L3 of the melt layer. The profile arrangement according to the invention can thus be individually adapted to the various building elements, furniture panels, and the like, as well as to the edge banding machines used, for optimal production.

[0012] A further advantage of the profile arrangement according to the invention is that the material of the melt layer has a melt viscosity of approximately 0.05 Pas to 15 Pas (Pascal seconds), preferably approximately 0.1 Pas to 10 Pas, at 210 °C according to ISO 2884 and, on at least one longitudinal edge L3, a width B3 that is approximately 0.5 - 4.7% smaller than the width B2 of the structural layer. A further advantage of the profile arrangement according to the invention is that the material of the melt layer has a melt volume rate (MVR) of 60 to 150 cm 3 / 10 min., preferably 85 to 125 cm 3 / 10 min., according to DIN ISO 1133 at 140 °C / 1.20 kg, and, on the longitudinal edge side, a width B3 that is approximately 0.5 - 4.7% smaller than the width B2 of the structural layer. This makes it possible to provide profile arrangements according to the invention which can be produced economically and cost-effectively and which can be mounted on the end faces of building elements, furniture panels and the like.can be fixed optically with almost no joint, which does not affect the manufacturing process of the building elements, furniture panels and the like and which has a high moisture resistance, particularly in the connection area to the end faces of the building elements, furniture panels and the like.

[0013] The profile arrangement according to the invention is further characterized in that the material of the melt layer has a melt viscosity of approximately 0.05 Pas to 15 Pas (Pascal seconds), preferably of approximately 6 Pas to 10 Pas, at 210 °C according to ISO 2884 and has a width B3 on at least one longitudinal edge side L3 that is approximately 0.5 - 2% smaller than the width B2 of the structural layer. Furthermore, the profile arrangement according to the invention is designed such that the material of the melt layer has a melt volume rate (MVR) of 60 to 90 cm 3 / 10 min., preferably 65 to 85 cm 3 / 10 min. according to DIN ISO 1133 at 140 °C / 1.20 kg and has a width B3 on the longitudinal edge side that is approximately 0.5 - 2% smaller than the width B2 of the structural layer.The invention has recognized that the profile arrangement can only be produced economically and cost-effectively if a melt layer which has a smaller width than the structural layer and which has such an optimal melt viscosity according to ISO 2884 is used in a building element, furniture panel and the like. After extensive tests with a wide variety of materials for the melt layer of the profile arrangements, it was surprisingly found that in the selected ranges of the melt viscosity of the material of the melt layer / : melt volume rate MVR, despite the smaller width of the melt layer, it is possible to visually close the end face of a building element, a furniture panel and the like economically and cost-effectively without a parting line, without the water resistance of the building element, the furniture panel and the like being impaired.

[0014] A further advantage of the profile arrangement according to the invention is that the material of the melt layer has a melt viscosity of approximately 0.1 Pas to 10 Pas (Pascal seconds), preferably of approximately 0.05 Pas to 5.5 Pas, at 210 °C according to ISO 2884 and has a width B3 on at least one longitudinal edge side L3 that is approximately 1.2 - 3.5% smaller than the width B2 of the structural layer. Another advantage of the profile arrangement according to the invention is that the material of the melt layer has a melt volume rate (MVR) of approximately 95 to 150 cm 3 / 10 min., preferably 95 to 125 cm 3 / 10 min. according to DIN ISO 1133 at 140 °C / 1.20 kg and has a width B3 on the longitudinal edge side that is approximately 1.2 - 3.5% smaller than the width B2 of the structural layer.Here too, it was surprisingly found through various tests that for these ranges of melt viscosity of the material of the melt layer, it is easily possible to produce the building elements, furniture panels and the like economically and cost-effectively precisely because of the even smaller width of the melt layer and that when attaching and fixing the profile arrangements according to the invention to the end faces of the building elements, furniture panels and the like, an optimized adhesive strength or peel strength with simultaneously better moisture resistance can be achieved.

[0015] In particular, due to the advantageous properties of the material of the melt layer of the profile arrangement according to the invention for building elements, furniture panels and the like, it can be used both adhesive-free and with energy from an energy source selected from the group consisting of a laser source, infrared source, ultrasound source, magnetic field source, microwave source, plasma source and hot air source and the like for edging the end faces of building elements, furniture panels and the like.

[0016] In a further advantageous embodiment of the profile arrangement according to the invention for building elements, furniture panels, and the like, it has been shown that the side of the structural layer opposite the molten layer has been subjected to a surface treatment using a corona process, flame treatment, plasma process, silicatization process, silanization process, and the like. This allows for an optimized bond between the molten layer and the structural layer of the profile arrangement according to the invention for building elements, furniture panels, and the like, optimized for a wide variety of material combinations, particularly the molten layer.

[0017] In a likewise advantageous embodiment of the profile arrangement according to the invention for building elements, furniture panels, and the like, it has been shown that the material of the melt layer and / or the material of the structural layer contains light- and / or radiation-absorbing additives in an amount of 0.01 to 5 wt. %, preferably 0.02 to 3.0 wt. %, based on the total amount. In this embodiment of the profile arrangement according to the invention for building elements, furniture panels, and the like, it can be optimally welded using known laser joining methods by the targeted introduction of energy into the material of the melt layer and / or the structural layer on the narrow sides of building elements, furniture panels, and the like.

[0018] It has also been found advantageous that the material of the melt layer and / or the material of the structural layer of the profile arrangements contains at least one additive, partially containing inorganic and / or organic pigments, in an amount of approximately 0.01 to 5.0 wt.%, preferably 0.02 to 3.0 wt.%, based on the total amount. This makes it possible to cost-effectively and economically apply the profile arrangement according to the invention to the end faces of building elements, furniture panels, and the like via the melt layer using all currently known radiation-activatable methods.

[0019] A further advantage of the profile arrangement according to the invention for building elements, furniture panels, and the like is that the additive of the melt layer and / or the structural layer of the profile element is selected from the group of metal oxides, metal phosphates, and metal salts of organic anions. By selecting the additives, a profile arrangement according to the invention can be provided that is optimized for the radiation-activated attachment methods but also tailored to the materials of the building elements, furniture panels, and the like.

[0020] In a further advantageous embodiment of the profile arrangement according to the invention for building elements, furniture panels and the like, the material of the melt layer of the profile arrangement has polar groups based on amides, amines, carboxylic acids or their esters or salts, in particular acrylic acid, acrylic acid esters, silanes, titanates, alcohols, imides, ammonium compounds or sulfonic acids or their esters or salts, blocked isocyanates or the like. Due to the various possibilities for arranging polar groups in the material of the melt layer, a profile arrangement according to the invention for building elements, furniture panels and the like can be provided in which the material of the melt layer has both polar and non-polar components.

[0021] By varying, in particular, the polar groups in the material of the melt layer, it is possible for the first time to provide a profile arrangement according to the invention for building elements, furniture panels and the like, in which the material of the melt layer is designed in such an optimized manner that, when used as intended, when the profile arrangement is materially bonded to the end face of the building element, furniture panels and the like, both optimal strength values ​​or peel strength values ​​as well as the same or better moisture resistance values ​​can be achieved.

[0022] A further advantage of the profile arrangement according to the invention for building elements, furniture panels and the like is that the material of the structural layer is polyvinyl chloride (PVC); polyolefin, such as polypropylene (PP) or polyethylene (PE); a styrene-based polymer, such as polystyrene (PS) or styrene-butadiene copolymer with a predominantly styrene content (SB) or acrylonitrile-styrene-acrylate copolymers (ASA) or acrylonitrile-butadiene-styrene copolymers (ABS) or styrene-acrylonitrile (SAN); polybutylene terephthalate (PBT); polyethylene terephthalate (PET); polyoxymethylene (POM); polyamide (PA); polymethyl methacrylate (PMMA); polyphenylene oxide (PPO); polyetheretherketone (PEEK); polyphenylene sulfide (PPS); liquid crystal polymer (LCP); polyamideimide (PAI); polyvinylidene fluoride (PVDF); polyphenylsulfone (PPSU); polyaryl ether ketone (PAEK); polyacrylonitrile (PAN); polychlorotrifluoroethylene (PCTFE); polyetherketone (PEK); polyimide (PI); polyisobutene (PIB); polyphthalamide (PPA); polypyrrole (PPY);Polytetrafluoroethylene (PTFE); polyurethane (PUR); polyvinyl alcohol (PVA); polyvinyl acetate (PVAC); polyvinylidene chloride (PVDC) as well as mixtures of at least two of these materials. Suitable fillers and / or reinforcing materials can be added to the polymeric material of the structural layer of the profile arrangement, which positively influence the mechanical properties, in particular glass fibers, glass beads, but also fillers such as chalk, talc, Teflon and the like. The fillers and / or reinforcing materials are contained in quantities of approximately 2 to 50 wt.%, preferably 5 to 35 wt.%, based on the total mass. This makes it possible for the first time to seal the geometry of the end faces of building elements, furniture panels and the like in an automated and optimized manner via a profile arrangement in a sealing and visually appealing manner.

[0023] Furthermore, the profile arrangement according to the invention for building elements, furniture panels and the like is advantageously designed such that the material of the melt layer and / or the structural layer of the profile arrangement contains at least one of the following additives: stabilizers to improve resistance to light, UV radiation and weathering; stabilizers to improve thermal and thermo-oxidative resistance; stabilizers to improve hydrolytic resistance, stabilizers to improve acidolytic resistance, lubricants, demolding aids, coloring additives, crystallization-regulating substances and nucleating agents, flame retardants, impact modifiers, fillers and / or plasticizers.Thus, a profile arrangement according to the invention for building elements, furniture panels and the like can be provided which, on the one hand, can be produced economically and cost-effectively, but which also significantly improves the adhesion strength values ​​or peel strength values ​​for building elements, furniture panels and the like, important moisture resistance, which have previously been known from the prior art.

[0024] The profile arrangement according to the invention for building elements, furniture panels and the like is further designed such that the material of the melt layer is arranged at a distance from the structural layer via at least one functional layer. This functional layer of the profile arrangement according to the invention for building elements, furniture panels and the like serves to ensure that an optimal bond between the material of the melt layer and the material of the structural layer can be realized at any time in a cost-effective and economical manner for a wide variety of material combinations, in particular the material of the functional layer. It has also been found to be advantageous if the functional layer has a thickness of approximately 0.5 to 15 µm, preferably 1 to 10 µm. For cost-effective and economical production, application quantities of approximately 1 to 40 g / m², preferably 5 to 30 g / m², can be applied.

[0025] It has further proven extremely advantageous that the material of the functional layer is selected from the group of polyurethanes (PUR), acrylates, chloroprenes, epoxy resins, ethylene vinyl acetates (e.g. EVA dispersions), polyvinyl acetates (PVAC dispersions) and the like, as well as mixtures of two or more of the aforementioned substances.

[0026] A further advantage of the profile arrangement according to the invention is that the functional layer has, at least in part, a smaller width B5 than the structural layer on at least one longitudinal edge side L5, and that the structural layer is arranged at a distance from the longitudinal edge side L5 of the functional layer on at least one longitudinal edge side L2. This enables economical and cost-effective production of the profile arrangement according to the invention and also enables optimized, virtually trouble-free production of building elements, furniture panels, and the like.

[0027] It has further proven advantageous that the melt layer of the inventive profile arrangement for building elements, furniture panels, and the like has a thickness of approximately 50 µm to 400 µm, preferably 100 µm to 300 µm, particularly preferably 100 to 250 µm. This advantageously results in not only economical and cost-effective production of the profile arrangement, but also in the melt layer being optimally adaptable to the respective geometry of the end faces of the building elements, furniture panels, and the like.

[0028] The profile arrangement according to the invention for building elements, furniture panels and the like is further characterized in that the profile arrangement fixed to the end faces of the building elements, furniture panels and the like via the melt layer has a peel strength of at least 15 N / cm according to DIN 2851, measured on building elements, furniture panels and the like.

[0036] In subsequent operations in the prior art, the remainder of the profile arrangement 1, which projects beyond the width B4 of the end face 40 of the component, furniture panel 4, is then reduced by machining processes on the longitudinal edge side until the width B2 of the structural layer 2 / the width B3 of the melt layer 3 corresponds approximately to the width B4 of the end face 40 of the component, furniture panel 4, as described below.
