Description

[0001] Profile arrangement and furniture panel

[0002] The invention relates to a profile arrangement, in particular an edge strip, with at least one strip core made of at least one polymeric material, wherein the strip core has a front side and a rear side arranged opposite thereto, wherein the strip core has at least one end side in the profile longitudinal direction L, wherein the material of the strip core is selected from the group of polyolefins, in particular polyethylene (PE) and / or polypropylene (PP). The invention further relates to the technical field of objects such as furniture panels and the like with at least one such profile arrangement.

[0003] Furniture panels such as table tops, worktops, cabinet doors, side panels of furniture such as cabinets, shelves, tables, etc. are generally made of wood-like materials and have their surfaces decorated.

[0004] The surfaces are covered, for example, with decorated foils, papers, etc. Furthermore, the surfaces of the furniture panels can also be printed and / or coated with paint or varnish.

[0005] The narrow end faces of the furniture panels must be fully covered to prevent moisture penetration and for aesthetic and design reasons.

[0006] To cover the narrow ends of such furniture panels, edge banding, edge strips, and edging strips are usually used, preferably made of thermoplastic materials. The application of such edge banding is often carried out mechanically, for example, using automated devices.

[0007] These edge strips are attached to the relevant narrow end face of the furniture panel in these automated devices, so-called edge banding machines, and fixed using, for example, a functional layer.

[0008] The width of the edge strips is generally greater than the thickness of the narrow end faces of the furniture panels, so after the edge strips are fixed in place, their protruding side edges are generally machined away, and this surface is subsequently optimized, for example, by polishing. Unfortunately, this subsequently removes the decoration already applied to the edge strips. This reworking results in a different design on a square furniture panel, for example, due to the machined side edges of the edge strips, which is negatively described as a "frame effect."

[0009] EP 1080854 A2 discloses a method for attaching cover strips / edge strips to the end faces of furniture panels. The method for attaching cover strips or edge strips made of thermoplastic material to the narrow end faces of furniture panels, in particular chipboard, fiberboard, or similar wood-based panels, is implemented in such a way that the cover strips / edge strips are applied directly to the end faces and adhesively bonded to the end faces. The cover strips / edge strips can be welded to the narrow end faces of the furniture panels. The joint or adhesive joint between the edge strip and the furniture panel is to be sealed mechanically or thermally.For this purpose, the cover strips / edge strips are used with an overhang on both sides in relation to the respective narrow end faces, so that the overhangs are melted to seal the joints and the melted material of the cover strip or edge strip is then removed to create cover strips that are congruent with the end faces, for example by machining using a scraper or the like.

[0010] DE 10006661 C1 describes another method for producing furniture panels with plastic decorative and protective strips (edge ​​strips). In this method, which can also be carried out mechanically, a protrusion of the edge strip relative to an adjacent section of the surface element, the furniture panel, is largely removed by machining, preferably by milling. Subsequently, at least the machined surface of the edge strip, which has whitening cracks, is moistened with a multi-component lubricating oil with high penetration properties, and the remaining protrusion is subsequently removed with a roller brush, thus creating a smooth transition between the surface element and the edge strip.

[0011] The multi-component lubricating oil, with its high penetration ability, penetrates into all cracks, especially in the area of ​​the stress whitening areas, and completely wets this surface. The multi-component lubricating oil is designed to ensure clean and smooth removal by the brushes during subsequent processing of the fully wetted plastic surface of the edge strip, thus completely removing the stress whitening areas and any glue or adhesive residue. The disadvantage of these processes is that the cost of producing such a surface element, such as a furniture panel, is very high due to the expensive materials and the number of different pre- and post-processing steps.

[0012] Another disadvantage of these processes is that the multi-component lubricating oil used contaminates the surfaces of the surface element, the furniture panel, as well as the bonding area and the edge strip, and may chemically attack these surfaces.

[0013] Another disadvantage of these processes is that in the case of furniture panels whose surfaces are printed and / or painted after machining the narrow sides of the edge strips, the narrow sides of the edge strips must also be at least partially printed and / or painted and the printing and / or painting does not adhere sufficiently to these narrow sides.

[0014] This is where the invention comes in, which has set itself the task of overcoming the disadvantages of the known prior art and of demonstrating a profile arrangement which can be produced economically and cost-effectively, which can be produced without problems using known automated production processes and which can be attached to the end faces of furniture panels and in which the optical and haptic properties, in particular of the narrow sides, are retained and are adapted to the optical and haptic properties of the furniture panel.

[0015] This object is achieved according to the invention by the features of claim 1. Further advantageous embodiments are described in the subclaims.

[0016] It has surprisingly been found that a profile arrangement, in particular an edge strip, with at least one strip core made of at least one polymeric material, wherein the strip core has a front side and a rear side arranged opposite thereto, wherein the strip core has at least one end side in the profile longitudinal direction L, wherein the material of the strip core is selected from the group of polyolefins, in particular polyethylene (PE) and / or polypropylene (PP), is characterized in that the material of the strip core has about 10 to 50 wt.%, preferably about 25 to 40 wt.%, particularly preferably 20 to 35 wt.%, based on the total weight, of at least one further polymeric material, in particular a copolymer which has polar monomers in the molecular structure.This now makes it possible to provide profile arrangements that are economical and cost-effective to manufacture, can be easily produced using conventional automated manufacturing processes, and can be attached to the end faces of furniture panels. The optical and tactile properties, particularly of the narrow sides, are retained and matched to the optical and tactile properties of the furniture panel. This makes it possible for the first time, particularly for subsequent decoration of the surfaces of furniture panels with pre-attached profile arrangements, to cost-effectively apply conventional printing and coating systems that also achieve sufficient adhesion to the material of the profile arrangement.

[0017] Furthermore, it was found that when the surface of the furniture panel is decorated with, for example, CPL laminate, HPL laminate and resin-impregnated paper materials, the adhesion to the material of the profile arrangement is optimized.

[0018] CPL laminate is a continuous pressure laminate produced in a continuous process from multiple layers of paper and resin, with thicknesses of approximately 300 μm. HPL laminate is a high-pressure laminate produced in a high-pressure press process in sheet form from multiple layers of paper and resin, with thicknesses of approximately 500 μm. Resin-impregnated paper materials, resin-impregnated papers, e.g., melamine papers, with thicknesses of approximately 30 to 100 μm.

[0019] A further advantage is that better adhesion of the material of the last core to cover layers made of polymer materials such as PET, PP, ABS can be achieved.

[0020] By adding another material to the core of the profile arrangement, particularly a copolymer with polar monomers in its molecular structure, the inherently non-polar polyolefins, particularly polyethylene and / or polypropylene, are particularly suitable for sealing the end faces of furniture panels with the usual quality. A further advantage of the profile arrangements is that by adding another material to the core of the profile arrangement, particularly a copolymer with sufficient hardness and temperature resistance and which blends well with the polyolefins during production, both the material price and production costs remain at a very low level, while at the same time the required raw materials are more readily available. Furthermore, the profile arrangement has a significantly lower "CO2 footprint" than profile arrangements in the known state of the art.Copolymers can be random, alternating, block and / or graft copolymers. Another advantage of the profile arrangement is that the material of the strip core preferably comprises at least one ethylene copolymer with at least 10 wt.% polar monomers, based on the total weight. Extensive tests have shown that with the addition of at least 10 wt.% polar monomers, based on the total weight, these can be realized with reliable adhesion, particularly in the case of subsequently applied printing and varnish systems. It has also proven advantageous that the material of the strip core of the profile arrangement preferably comprises an ethylene copolymer with approximately 10 to 50 wt.%, preferably approximately 25 to 40 wt.% polar monomers, based on the total weight.

[0021] It is also advantageous in the profile arrangement that the material of the strip core preferably comprises at least one ethylene copolymer with at least 10% by weight of polar monomers, based on the total weight.

[0022] The profile arrangement is advantageously also designed such that the copolymer in the material of the strip core 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, as well as mixtures thereof.

[0023] An advantage of the profile arrangement is that the copolymer is selected from the group of carboxylic acid esters, in particular from the group of acrylic acid esters, preferably from the group of methyl acrylate, butyl acrylate and.

[0024] A further advantage of the profile arrangement is that the copolymer is selected from the group of ethyl acetate and / or from the group of anhydrides, preferably maleic anhydride and the like.

[0025] It is also advantageous in the profile arrangement that the copolymer has a methyl acrylate content or a vinyl acetate content or a butyl acrylate content of at least about 10% by weight, based on its total weight.

[0026] Thanks to all these advantageous configurations, the material of the strip core of the profile arrangement can be manufactured or adjusted in such a way that it is both economical and cost-effective to manufacture, can be easily attached to the end faces of furniture panels, and has sufficient adhesion, particularly when printing or coating systems are subsequently applied. The profile arrangement is further designed such that the material of the strip core can be advantageously characterized, in particular by the dielectric loss factor tan δ. The dielectric loss factor is a measure of the energy that is converted into heat in an insulating material located in an alternating electric field and is thus lost as electrical energy.

[0027] Dielectric properties are material constants that are largely independent of the methods used to determine them (see IEC 62631-2-2 VDE 0307-2-2:2021-07). However, since their value changes with temperature and frequency, they are usually expressed as a function of these parameters. For the heating of a plastic in a dielectric, the tan δ is a crucial material property.

[0028] Furthermore, the profile arrangement is designed such that the material of the strip core can advantageously be characterized such that its electronegativity difference AEN is in a range of approximately 0.4 to 1.7, preferably 0.5 to 1.5, i.e., one atom in the material demands electron pairs much more strongly than the other. The electronegativity difference (also called delta-EN, AEN) is the difference in the electronic activities of the atoms involved in a material bond. To determine whether a material is nonpolar or polar, it is expedient to use the electronegativity difference.

[0029] These two advantageous embodiments alone make it possible for the first time to adjust the inherently polar material of the strip core of the profile arrangement in such a way that subsequently applied printing and varnish systems can be reliably applied.

[0030] Another advantage of the profile arrangement is that the material of the last core comprises at least one copolymer with a melting temperature range of approximately 50 to 110 °C, preferably 60 to 105 °C according to DIN EN ISO 3146:2022-06. This not only results in economical and cost-effective production of the profile arrangement, but also allows the copolymer to be incorporated into the last core material with low energy intensity.

[0031] The profile arrangement is further characterized by the fact that the material of the last core has a melt flow index (MFI) of approximately 0.5 g to 60 g / 10 min., particularly preferably 0.5 g to 50 g / 10 min., according to DIN ISO 1133-1:2012-03 at 230 °C / 2.16 kg. This allows the profile arrangement to be produced economically and cost-effectively using conventional primary forming processes such as extrusion, co-extrusion, and post-co-extrusion. Another advantage of the profile arrangement is that the material of the last core has a Shore D / 3 hardness of approximately 45 to 70, preferably 50 to 68, according to DIN EN ISO 868:2003-10.

[0032] Thus, the profile arrangement is sufficiently strong / stable and advantageously has an E-modulus of at least 1,400 MPa and a tensile strength of at least 30 MPa according to DIN EN ISO 527-1:2019-12, so that the profile arrangement can be easily attached to the end faces of furniture panels, particularly in automated manufacturing processes.

[0033] Another advantage of the profile arrangement is that the material of the strip core contains approximately 5 to 50 wt.%, preferably approximately 5 to 40 wt.%, particularly preferably 5 to 35 wt.%, based on its total weight, of at least one filler. Advantageously, the filler is selected from the group of phyllosilicates, as well as carbonates or sulfates of barium and calcium, and the like, in particular barium sulfate, talc, and chalk.

[0034] A further advantage of the profile arrangement is that the filler in the strip core material has a particle size with a D50 value of approximately 0.2 to 25 pm, preferably 0.5 to 20 pm, particularly preferably 1 to 15 pm according to DIN 66165-1:2016-08. The profile arrangement can thus be manufactured economically and cost-effectively. Furthermore, it can be easily adapted to the required geometry of the furniture panels (square, round, etc.).

[0035] It has also proven advantageous for the profile arrangement to include at least one identification element. This allows the origin or manufacturer of the profile arrangement, as well as material or environmental data, to be easily attached or read.

[0036] The profile arrangement is further characterized in that the material of the strip core contains at least one additive, partially containing inorganic and / or organic pigments, in an amount of approximately 0.01 to 5 wt.%, preferably 0.02 to 3.0 wt.%, based on the total amount. Another advantage of the profile arrangement is that the additive of the strip core is selected from the group of metal oxides, metal phosphates, and metal salts of organic anions.

[0037] Another advantage of the profile arrangement is that the back of the strip core has a functional layer, at least in sections. This functional layer can advantageously be a so-called adhesion promoter layer and / or a so-called hot-melt adhesive layer and / or a so-called polymeric functional layer.

[0038] The profile arrangement is advantageously further designed such that the material of the strip core 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.

[0039] In a further, likewise advantageous embodiment, the profile arrangement is designed such that at least one cover layer with a thickness of approximately 2 to 60 pm, preferably 5 to 30 pm, is arranged on the front side of the strip body.

[0040] Alternatively, it is possible for the profile arrangement to be manufactured using a generative manufacturing process, e.g. a 3D printing process.

[0041] For the production of the profile arrangement, it is advantageous to use three-dimensional models that can be read by data processing machines.

[0042] The invention also includes a method for generating a data processing machine-readable, three-dimensional model for use in a manufacturing process for a profile arrangement.

[0043] In particular, the method also includes inputting data representing a profile arrangement into a data processing machine and using this data to represent a profile arrangement as a three-dimensional model, wherein the three-dimensional model is suitable for use in the manufacture of a profile arrangement. The profile arrangement can be manufactured entirely or partially using a line-based or layer-based manufacturing process. A 3D data set can be used to great advantage during construction or production.The method also encompasses a technique in which the input data from one or more 3D scanners, which operate either contact-based or contactless, with the latter delivering energy to a profile arrangement and receiving the reflected energy, is processed, and a virtual three-dimensional model of a profile arrangement is generated using computer-aided design software. The manufacturing process can comprise a generative powder bed process, in particular selective laser melting (SLM), selective laser sintering (SLS), selective heat sintering (SHS), selective electron beam melting (EBM / electron beam additive manufacturing - EBAM), or binder jetting of powder material.The manufacturing process can comprise a generative free-space process, in particular deposition welding, wax deposition modeling (WDM), contour crafting, metal powder deposition (MPA), plastic powder deposition, cold gas spraying, electron beam welding (EBW), or melt layering processes such as fused deposition modeling (FDM) or fused filament fabrication (FFF). The manufacturing process can comprise a generative liquid material process, in particular stereolithography (SLA), digital light processing (DLP), multi-jet modeling (MJM), polyjet modeling, or liquid composite molding (LCM). Furthermore, the manufacturing process can comprise other generative layering processes, in particular laminated object modeling (LOM), 3D screen printing, or light-controlled electrophoretic deposition.

[0044] The invention further relates to an article such as a furniture panel, table top, worktop and the like with at least one profile arrangement according to the previous embodiments.

[0045] The invention also relates to an article, such as a furniture panel, which is characterized in that the profile arrangement is attached, in particular fixed, to at least one end face of the furniture panel.

[0046] The invention further relates to an article such as a furniture panel, which is designed such that the profile arrangement attached to the end face of the furniture panel has at least one bevel and / or at least one radius on at least one end face arranged in the profile longitudinal direction L. The invention further relates to an article such as a furniture panel, which is advantageously designed such that at least one surface of the furniture panel and the profile arrangement attached to the end face of the furniture panel have at least one partial coating on at least one end face arranged in the profile longitudinal direction L. This coating can be designed as a decorated film and / or as a printed layer and / or as a painted layer.

[0087] In this exemplary embodiment, the object such as furniture panel 10 is designed such that the profile arrangement 1 is integrally connected, in particular fixed, to the end face 11 of the furniture panel 10 via a functional layer 7, which is arranged on the rear side 4 of the strip core 2 of the profile arrangement 1.

[0088] The object such as furniture panel 10 is advantageously designed such that the profile arrangement 1 attached to the end face 11 of the furniture panel 10 has at least one chamfer 80 and / or at least one radius 90 on at least one of its end faces 8, 9 arranged in the profile longitudinal direction L.

[0089] Furthermore, the object such as furniture panel 10 is advantageously designed such that at least one surface 12 of the furniture panel 10 and the profile arrangement 1 attached to the end face 11 of the furniture panel 10 have at least partially a coating 20 on at least one of its narrow sides 8, 9 arranged in the profile longitudinal direction L.

[0090] In this exemplary embodiment, the coating 20 is arranged over the entire surface 12 of the furniture panel 10, which is designed as the visible side, and at least partially covers the first narrow side 8 of the strip core 2 of the profile arrangement 1.

[0091] However, it is also within the scope of the invention that the coating 20 covers the entire narrow side 8,9 of the strip core 2 of the profile arrangement 1.

[0092] Advantageously, the coating 20 is designed such that it has the same / identical decoration as the front side 3 of the strip core 2 of the profile arrangement 1.

[0093] The coating 20 can be designed as a printing and coating system. Thus, especially in the case of subsequent decoration of the surfaces 12, 13 of the furniture panel 10 with previously fixed profile arrangements 1, it is now possible for the first time to cost-effectively apply known printing and coating systems that also achieve sufficient adhesion to the material of the strip core 2 of the profile arrangement 1.

[0094] However, it is also within the scope of the invention that the coating 20 is designed as a film, in particular as a polymer film.

[0095] The coating 20 formed as a polymeric film advantageously has a thickness of approximately 5 to 100 pm, preferably 20 to 80 pm.
