Abstract

In a profile part (1) for a window and/or a door, comprising an extrusion profile (3) made of plastic and a laminated decorative layer (6), in particular facing the interior of the building, it is provided that the decorative layer is an intermediate layer to be connected to the extrusion profile (5) and has an associated cork layer.

Description

The present invention relates to a profile part for a window and/or a door, in particular for a window or door frame, a window or door sash or a glazing strip, as well as a method for producing such a profile part. The invention also relates to a door and/or window frame or a door and/or window sash with a profile part.

It is known in the prior art to increase the attractiveness of door and/or window frames by laminating the visible outside or inside of the frames with a plastic film, which, for example, has a wooden appearance, a concrete-like appearance, a cork look or similar should imitate. The use of plastic is increasingly frowned upon these days. There is therefore a fundamental demand for more environmentally friendly products. At the same time, the demand for customer-specific, individualized door and/or window frame parts with a cork surface is increasing.

Processing pure cork is technically complicated and therefore cost-intensive. Attempts to apply pure cork to visible surfaces of extruded plastic profiles for windows or doors have not led to qualitatively or economically satisfactory results. Attempts were also made to provide a plastic extrusion profile as a coextrusion profile with a coextruded surface layer containing powdery and/or fibrous cork, but these also did not lead to the desired results.

It is the object of the present invention to overcome the disadvantages of the prior art, in particular to simplify the production of individualized and/or environmentally friendly profiles for window and/or door frame parts or window and/or door leaf parts.

The task is solved by the subjects of the independent claims.

Accordingly, a profile part is provided for a window and/or a door, in particular for a window or door frame, a window or door sash or a glazing strip. The profile part includes an extrusion profile made of plastic and a laminated decorative layer. The extrusion profile includes or consists of plastic. The plastic of the extrusion profile comprises or consists of at least one thermoplastic, preferably polyvinyl chloride (PVC). The extrusion profile can be, for example, a profile made in particular from plastic, such as PVC, in particular an extrusion profile, for example a mono-extrusion profile or a co-extrusion profile. The extrusion profile generically comprises an extrusion semi-finished product produced by extrusion, which has a substantially identical cross section along the extrusion direction and a substantially identical external dimension. Generic extrusion profiles can be produced, for example, by pulling or using the extrusion process. In the context of the present invention, the terms extrusion profile, mono-extrusion profile and co-extrusion profile are to be understood as meaning that the corresponding profile is produced by extrusion, mono-extrusion or co-extrusion. The extrusion process can be monoextrusion or coextrusion.

The profile part can, for example, at least in sections form a door and/or window part, such as a spar, such as a vertical spar or a horizontal spar. The profile part can, at least in sections, form at least a fixed door and/or window frame part or a movable, in particular displaceable and/or pivotable, door and/or window sash part.

According to the invention it is provided that the decorative layer has an intermediate layer to be connected to the extrusion profile and a cork layer connected to the intermediate layer.

The cork layer is arranged on the visible side of the decorative layer. The cork layer preferably comprises or consists of a granular cork material, a strip-shaped cork material and/or a flat cork material. Flat cork material can form a coherent composite of 100 cm ² or more and can preferably essentially correspond to a circumferential annual ring layer. Strip-shaped cork material can realize a coherent composite with a composite length that is greater than the composite width, whereby the orientation of the cork strips can be realized parallel and/or transversely to an annual ring layer. Granular cork material includes a large number of different cork parts with, in particular heterogeneous or homogeneous, a width in the range of 0.1 mm to 50 mm.

The intermediate layer is designed and set up to provide a permanent and firm connection of the cork layer to the plastic extrusion profile. The intermediate layer is preferably designed and set up to provide a minimum adhesive force of at least 1 N/mm ² , in particular at least 2 N/mm ² , preferably at least 2.5 minutes per mm ² . The cork layer and the intermediate layer are preferably integrally connected to one another. For example, the cork layer forms a laminate and/or impregnate with the intermediate layer. The profile part has a multi-layer structure in which the cork layer is arranged on the visible surface of the profile part, the extrusion profile behind the cork layer and the intermediate layer between the cork layer and the extrusion profile. The profile part preferably consists of a cork layer, the intermediate layer and the extrusion profile. The intermediate layer is preferably cork-free.

The decorative layer can be a linear, elongated structure with a cross-sectional shape that is round, square, or the like, and is thin and flexible in relation to its length. Laminating generally refers to the joining of several layers using a laminating agent, in particular comprises at least one adhesive, understood. Laminating the particularly thin and/or flexible decorative layer with a cork layer has proven to be particularly advantageous with regard to production, since on the one hand the decorative layer with a cork layer can be stored in a simple and space-saving manner, for example by winding it onto a storage roll. The decorative layer is elastically stretchable or bendable to a certain extent, in particular in such a way that it can be easily applied to non-flat profile surfaces and its shape can be adapted in this regard. According to the present invention, a decorative layer can be understood as flexible if it can be wound or rolled up on a roll, in particular for storage. The thin decorative layer adapts and laminates itself to even irregular profile outsides in a particularly form-fitting and true-to-shape manner, so that an even, long-lasting and precisely fitting lamination of the corresponding profile outside can be guaranteed. Another advantage is that the decorative layer does not have to be exactly dimensioned in relation to the surface of the outside of the profile to be laminated, but can be dimensioned larger, since this can be separated using simple post-processing steps, such as trimming. Laminating the metal layer, in contrast to subsequently attaching it, also has the manufacturing advantage in that the lamination process can be integrated directly into the extrusion process.

In a preferred embodiment, the intermediate layer of the profile part comprises a fiber material or consists of a fiber material. Such an intermediate layer can be referred to as a fiber layer. The intermediate layer can be a linear, elongated structure with a cross-sectional shape that is round, square, or the like, and is thin and flexible in relation to its length. As a rule, fibers of the intermediate layer are characterized by the fact that they cannot absorb compressive forces in the longitudinal direction, but only tensile forces.

In a further development of the invention, the fiber material is selected from the group comprising felt, braid, knitted fabric, woven fabric, knitted fabric, artificial leather, paper, cardboard and fleece. Preferably, the fiber material is a textile fiber material, such as a fleece, a woven fabric, a knitted fabric, a knitted fabric, a braid and/or felt. For example, this is Textile fiber layer is formed into a flat textile structure, such as a fleece, a fabric, in particular plain weave, a knitted fabric, a knitted fabric, a braid and/or felt. The textiles can be, for example, woven cotton, velvet, printed cotton, katun, satin, silk, burlap or similar. For example, the textile can consist of 100% polyester and/or be woven and/or be pigmented at least on one side and/or be provided with a PUR coating. Plain weave has proven to be useful because fabric produced in this way has little tendency to fray when necessary trimming in the lamination and/or when milling the profile at a window manufacturer.

According to a preferred development of the invention, the fiber material comprises or consists of a polyester fleece. According to an alternative development, the fiber material comprises or consists of a cotton fabric. In a further alternative development, the intermediate layer comprises or consists of an artificial leather containing polyurethane.

In one embodiment of a profile part according to the invention, the intermediate layer comprises or consists of a plastic material, in particular selected from the group consisting of polyvinyl chloride, polyurethane or any mixtures thereof. In particular, a coating or a carrier film creates the intermediate layer.

One embodiment of a profile part according to the invention, which can be combined with the previous ones, provides that the decorative layer is at least partially laminated on an outside of the extrusion profile by means of an adhesive.

In a preferred development, the adhesive is a particularly one-component hot melt adhesive, in particular based on PU. Furthermore, a layer thickness of the adhesive can be greater than 60 g/m ² , in particular in the range from 80 g/m ² to 100 g/m ² . The layer thickness can also be in the range from 80 g/m ² to 100 g/m ² . The adhesive can be, for example, a so-called PUR hotmelt, in particular a reactive PU hotmelt, which, in addition to solidifying when cooled, also hardens chemically, usually with the inclusion of moisture, and thus builds up particularly high adhesion. Such Hot melt adhesives, also known as hot melt adhesives, hot glue or hot melt, are generally solvent-free or water-free and/or generally solid at room temperature adhesive types that are present as a viscous liquid when heated and can therefore be reliably applied to an adhesive surface to be bonded Cool and reversibly solidify to create a firm connection between the bonding partners. These types of adhesives typically include or consist of thermoplastic polymers.

In an exemplary embodiment of the profile part according to the invention, the cork layer or the decorative layer comprises at least 50%, in particular at least 60%, 70%, 80% or at least 90%, cork.

In a further exemplary embodiment of the present invention, the decorative layer has a thickness of less than 1.0 mm, in particular a thickness in the range from 0.1 mm to 0.7 mm. The decorative layer with cork layer preferably has a layer thickness of 0.4 mm to 0.6 mm. Lower layer thicknesses generally show unsatisfactory covering properties. Greater layer thicknesses have proven to be disadvantageous in terms of processing.

In an exemplary embodiment of the profile part according to the invention, the intermediate layer comprises at least 50%, in particular at least 60%, 70%, 80% or at least 90%, fiber material. Preferably, the fiber material can comprise or consist of natural fibers. Natural fibers are all fibers that come from natural sources, such as plants, animals or minerals, and/or are present without any further chemical additives. Furthermore, the fiber layer can be made from renewable raw materials to at least 50%, in particular at least 60%, 70%, 80% or at least 90%. For example, the fibers are regenerated fibers that are made from naturally occurring, renewable raw materials via chemical processes, for example based on cellulose.

Depending on the type of light, ultraviolet (UV) rays and infrared (IR) rays act on extrusion profiles, for example made of plastic, for window and/or door parts, in particular window and/or door frame parts or window and/or door leaf parts different intensity. Since such extrusion profiles are permanently exposed to weather conditions, especially UV radiation, for a long time, these rays can, over time, trigger reactions in the plastic material that lead to embrittlement and/or fading.

According to the invention, light fastness can be determined by any method familiar to those skilled in the art. For example, the light fastness can be determined by an exposure method according to DIN 513: 1999-10, in which the color temperature is measured at a total irradiation power of approximately 12 GJ/m ² in the wavelength range from 300 nm to 800 nm. The individual steps of the process for determining light fastness and weather fastness will be discussed in detail later in the examples.

In a further exemplary embodiment, the profile part, in particular the decorative layer, is at least partially coated with a lacquer. The decorative layer is preferably completely coated with a lacquer. A varnish is generally a liquid or powdery coating material that is applied to the connecting surface, for example sprayed, rolled on or the like, and usually forms a continuous solid film from the surface.

In an exemplary embodiment of the profile part according to the invention, the paint comprises polyester gel paint, epoxy resin paint, alkyd resin paint, acrylic paint, PU paint and/or a PVDF coating.

Alternatively, the profile part can be designed without a paint coating on the decorative layer. By dispensing with the lacquer coating, simpler and more cost-effective production can be achieved.

According to a further aspect of the present invention, which can be combined with the preceding aspects and exemplary embodiments, a door and/or a window part, in particular a preferably fixed door and/or window frame or a preferably movable door and/or window sash, is provided . The door and/or window part according to the invention or the door or window according to the invention comprises at least one Profile part according to the invention. Furthermore, it can be provided that the frame or the wing, in particular the door or the window, comprises at least one profile part produced using the method according to the invention.

Preferred embodiments are specified in the subclaims.

Further properties, features and advantages of the invention will become clear below by describing preferred embodiments of the invention with reference to the accompanying exemplary drawings, in which:

Figure 4

a schematic representation of a section of a manufacturing system for a profile part according to the invention.

In Figure 1 is a plastic extrusion profile, which is generally provided with the reference number 100, shown in a sectional view, onto which a cover 105, for example with a print in a cork look, is attached to an outside facing away from the building interior, on the one hand to the plastic To give the extrusion profile a cork look and, on the other hand, to protect the extrusion profile from the effects of the weather using the cover. A glazing 107 is inserted into a receptacle 109 and sealed on both sides of the glazing 107 from the adjacent profile parts of the extrusion profile 100 by means of two sealing elements 111, 113.

The extrusion profile 100 according to Figure 1 is constructed in several parts and, in addition to a profile base 115, has a blind profile 117 facing the interior of the building, which on the one hand is positively connected to the profile base 115 and which has a sealing surface 119 to which a seal 111 is attached for sealing against the Glazing 107. The profile base 115 has a substantially L-shaped outer contour in the sectional view, so that towards the outside the profile base 115 overlaps with the glazing 107, the overlap area being covered with a seal 113, the so-called glazing seal 113, around the glazing 107 to be sealed on both sides. An extrusion profile outside 121 facing away from the interior of the building is formed by a substantially straight-line extending profile outer web 123 of constant wall thickness, which merges in one piece into a sealing web 125 arranged at an angle to the profile outer web 21, which extends in the direction of the glazing 107 to limit a sealing gap 127 to be sealed.

The panel 105 is adapted to a shape of the profile outer web 123 and the sealing web 125, so that the panel 105 completely covers the extruded plastic profile 103 to the outside. In the area of the glazing 107, the sealing gap 127 is formed between an angled end section 129 of the cover 105 and the flat extension of the glazing 107. A glazing seal 113 specially formed for the extrusion profile 103 is inserted in this area. In comparison to plastic extrusion profiles without a cover 105, the glazing seal 113 has been modified in order to be able to seal the resulting different sealing gap dimensions 127.

At the other end 131 of the panel 105, the panel 105 has an end section with a U-shaped cross section, which is arranged around one end of the profile outer web 123. Through the angled ends 129, 131, the panel 105 is positively attached to the plastic extrusion profile 103, namely plugged on and clipped on.

In the following description of preferred embodiments of the invention, the same or similar reference numbers are used for the same or similar components to simplify readability.

With reference to Figure 2 An exemplary embodiment of a profile part according to the invention, which is generally provided with the reference number 1, is described. To avoid repetition, the same or similar components are given the same terminology, with the reference numbers reduced by 100. In the exemplary embodiments of the profile part 1 of the invention Figures 2 to 6 are, for example, extrusion profiles 1 made of plastic, in particular PVC, which are produced by extrusion and provided with a decorative layer 6. Extrusion can be done using mono- or co-extrusion.

In contrast to the attached and locked panel 105, the decorative layer 6 is laminated with cork layer on the profile outer web 23 facing away from the interior of the building. The decorative layer 6 has a layer thickness of less than 1.0 mm, which is constant along its longitudinal extent and flexible due to the thin dimensions. It is clear that the decorative layer 6 can also be laminated on an inside profile inner web 22 opposite the profile outer web 23 or that this can also be laminated with a decorative layer 6 in order to also give the extrusion profile 3 a desired look on the inside. The manufacturing process will be discussed in detail later. One advantage of laminating the decorative layer 6 is that, on the one hand, the decorative layer 6 rests on the extrusion profile 1, so that a particularly compact structure is achieved. Furthermore, the decorative layer 6 can be dimensioned such that it essentially exclusively covers the visible area of the corresponding profile webs 23, 22 of the extrusion profile 3. It is not necessary for the decorative layer 6 to protrude into the sealing gap 27, for example in the area of the glazing, for example to ensure fastening. The same applies to the other end of the profile outer web 23, which the decorative layer 6 does not have to encompass. In the area of the glazing 7, this has a particularly advantageous effect, since the standard glazing seals 13 can be used, so that no special designs for the glazing seal 113, such as when using the cover 105, are necessary. Fastening by means of lamination is significantly stronger and therefore more durable than with the state-of-the-art clipping of additional panels 105.

In Figure 3 a schematic section of an extrusion profile 1 according to the invention is shown. The layer structure shown schematically here will now be described starting from bottom to top. A so-called primer 31 is first applied to the plastic extrusion profile 3, which ensures particularly good adhesion subsequent adhesive 33 guaranteed. The decorative layer 6 can be at least partially coated with an adhesive base 37 at least on the connecting surface 35 facing the plastic extrusion profile 3.

In Figure 3 It can also be seen that an optional varnish 39, such as a top coat or a clear varnish, can be introduced between the adhesive base 37 and the adhesive layer 33. For example, in the case of decorative layers 6 with a textile intermediate layer 5, the use of a lacquer layer 39, for example made of acrylic, polyester, epoxy resin or a PU lacquer, has proven to be advantageous in that the milling suitability can be significantly increased, which is the case when cutting the decorative layer 6 to length and / or when Milling out openings (not shown), for example for window handles or fittings or the like, is advantageous. The profile part 1 coated with the paint 39 no longer frays so easily, so that the quality of the decorative layer 6 is significantly increased.

The decorative layer 6 comprises a cork layer on the outer visible surface and, connected to the cork layer, an intermediate layer 5 on the connecting surface facing the extrusion profiles. The intermediate layer 5 can be formed from a fiber material, for example a textile material, such as a fleece or a woven fabric, or paper.

In Figure 4 The manufacturing process for producing an extrusion profile 1 according to the invention and in particular for laminating decorative layers 6 is shown schematically and is explained in more detail below: Figure 4 shows a section of a manufacturing system 40 for producing an extrusion profile 1 according to the invention, into which an extrusion semi-finished product 41 produced by an extrusion tool (not shown) is conveyed (from the right in the illustration). Basically, the laminating system 40 is divided into the following stations: inlet area 43, primer area 45, turning area 47 and outlet area 49. Basically, the extrusion semi-finished product 41 and the later finished extrusion profile are conveyed through the laminating system 40 by means of a large number of conveyor rollers 51 in the longitudinal direction of the extrusion profile in accordance with a conveying direction F. In the inlet area 43, the extrusion semi-finished product 41 is delivered essentially with a profile temperature in the range of 18 ° C to 25 ° C. In the primer area 45 there is a primer station 53 for applying the primer evenly and over the entire surface to the side of the extrusion profile to be covered with the decorative layer 6, which can be designed, for example, as an inside or an outside 22, 23 of the window or door to be manufactured. An application and drying section 54 for the primer is provided between the primer area 45 and the folding area 47.

In the folding area 47, the decorative layer 6 to be laminated with cork layer is stored on a roller 56. A strand 57 of the decorative layer 6 to be laminated is then continuously rolled off from the roller 46 essentially synchronously and / or coordinated with the conveyance F of the extrusion semi-finished product 41 and coated on one side on a laminating surface with adhesive, which is applied by means of a nozzle 59 upstream of a laminating roller 61, which the Decorative layer 6 is pressed onto the plastic extrusion profile 3 and is applied.

In contrast to the state of the art PVC film lamination on plastic extrusion profiles, it was found that the amount of adhesive must be significantly increased to improve the adhesive effect of decorative layers and, in particular, adhesive amounts in the range of 80 g/m ² are necessary. Furthermore, the decorative layer 6 is preheated immediately before the adhesive is applied, and it has been found that significantly higher temperatures are necessary, for example in the range from 50 ° C to 130 ° C. For good adhesion, it has been identified that a temperature of at least 55°C, in particular at least 57°C - 59°C, must be maintained in the area of the laminating roller 61. Optionally, a hot air blower or another heat air generator 63 can be connected to the laminating roller 61.

Trimming can be carried out using a separating device 65. Subsequently, a further application of protective films can be carried out, particularly in the area of the profile outlet 49, which are provided by respective rollers 67, 69 and are applied to the top and bottom 22, 23 of the extrusion profile 1 according to the invention. This can be done using an adhesive applied to the protective films.

The features disclosed in the above description, the figures and the claims can be important both individually and in any combination for the implementation of the invention in the various embodiments.
