    The invention relates to an expansion plate with a planar heating element for the interior design and a method for producing such a mounting plate, including planar heating element.
    In this context, WO 2007/131705 A1 discloses an electrically operable surface heating element, in particular for use in wall construction of a building interior, wherein a corresponding wall heating plate in a sandwich arrangement consists of a first plasterboard panel (in the installed state on the rear side), of a second plasterboard panel (in the installed state, the room-side viewing side) and an embedded between the two plasterboard heating foil consists. In the finished state thus the first plasterboard, the heating foil and the second plasterboard are firmly connected. The wall heating plate can be designed at room height, wherein the heating foil is subdivided into a plurality of heating fields and has laterally flat electrode strips which serve for the electrical contacting of the heating foil. According to one embodiment variant, the wall heating plate can also consist of a plasterboard as a base support and a heating foil attached thereto, which can likewise be subdivided into partial heating fields and has lateral copper strips for electrical contacting. On the heating foil a laminating film is attached as a protective and insulating film, on the visible side of the surface pattern is printed according to the underlying Teilheizfeldern and copper strips.
    Furthermore, from WO 2011/055330 Al a Heizpaneel on the basis of a plasterboard has become known. It describes a manufacturing process in which a first layer of web material is continuously coated with a hardening layer (e.g., plaster layer), with a planar heating element being introduced prior to the application of the top web material. The heating element can have a very wide variety of structures, wherein, according to one embodiment variant, the printing of the inside of the upper material web with an electrical resistance layer is also provided as the heating element.
    Through long-term studies could be found that the contact of the heating foils or heating layers of the surface heating elements with the cardboard layer of plasterboard conventional heating panels over time can lead to embrittlement and cracking, which is associated with a sensitive drop in heating power and can lead to total failure of Heizpaneele ,
    Object of the present invention is to improve an expansion plate with a flat heating element for interior design based on the above-mentioned prior art such that despite a simple production of the expansion boards, the original heating power of the heating elements can be guaranteed as long as possible and total failures can be avoided ,
    This object is achieved in that between the heating layer and the surface of the paperboard layer, an intermediate layer is arranged, which is formed as a barrier against the mass transport between the heating layer and the paperboard layer.
    An inventive method for producing such a mounting plate is characterized in that prior to the application of a heating layer of the planar heating element on the surface of one of the board webs an intermediate layer is printed, sprayed or laminated, which serves as a barrier against the mass transfer between the heating layer and the board web ,
    The intermediate layer according to the invention stops the migration and diffusion processes between the heating layer and the paper or cardboard layer of the plasterboard, so that embrittlement and cracking over long periods of time can be avoided. This means that the heating power of the heating panels can be kept constant longer.
    According to a first embodiment of the invention, the surface heating element is arranged between the gypsum core and the inner surface of one of the two cardboard layers and thereby integrated directly into the plasterboard. In particular, in this embodiment, it may be advantageous if between the gypsum core and the heating layer of the surface heating element, a further intermediate layer is arranged, which is designed as a barrier layer against the mass transport between the heating layer and the gypsum core. The heating layer is thus protected on both sides by barrier layers against migration and diffusion processes, whereby a long-term, trouble-free operation of the heating panels is guaranteed.
    According to a second embodiment of the invention, the surface heating element is arranged on the outer surface of one of the two cardboard layers and covered by a cover layer, for example of a nonwoven material.
    The intermediate layer is preferably a polymer layer and consists for example of polyurethane, acrylic, polyester or other plastic layers to avoid migration and diffusion processes, with a layer thickness of 5 to 200 pm, preferably from 10 to 50 pm.
    According to the invention, the intermediate layer facing the paperboard layer is printed on the surface of the paperboard layer, at least in the region of the heating layer, applied as a lacquer layer or laminated as a foil.
    The further intermediate layer can be printed or sprayed directly onto the heating layer of the surface heating element or laminated as a foil.
    The invention will be explained in more detail below with reference to partly schematic drawings. Show it

    Fig. 5 shows a detail of the expansion plate according to the invention in a plan view and
    Fig. 6 is a section through the expansion plate of FIG. 5 along the line VI-VI.
    Functionally identical parts are provided in the individual embodiments with the same reference numerals.
    The expansion plate 1 shown in Fig. 1 with an integrated, flat heating element 10 for interior design based on a conventional plasterboard 2 and can be made with the usual market external dimensions and wall thicknesses, so that the expansion plate according to the invention is largely compatible with such plasterboard and are processed in the same way can.
    The plasterboard 2 consists essentially of a first cardboard layer 3 (base layer) and a second cardboard layer 4 (room-side cardboard layer), between which a gypsum core 5 is arranged. The heating element 10 has flat, lateral connection electrodes 6 made of a material with good conductivity (for example, strips of copper or silver material and conductive alloys and mixtures, which can preferably be applied by means of printing techniques), which contact the electrically operable heating layer 7 made of an electrical resistance material.
    The heating layer 7 of the Flächenheizelementes 10 may for example consist of a printable, pasty material with electrically conductive particles such as graphite, carbon fibers, etc. or nanoscale particles such as carbon nanotubes, graphene, etc. and applied to a carrier foil 8.
    To prevent diffusion and migration processes, in particular of components of the heating layer 7 in the cardboard layer 4, an intermediate layer 13 is arranged between these two components, which is designed as a barrier layer against the mass transport between the heating layer 7 and the cardboard layer 4.
    Furthermore, the carrier film 8 may be formed as a barrier layer 19 which is arranged between the gypsum core 5 and the heating layer 7 of the surface heating element and serves to prevent the mass transfer between the heating layer 7 and the gypsum core 5.
    The heating layer 7 (and the intermediate layers 13 and 19) may also extend over the entire length of the plasterboard 2, so that the free areas shown in Figs. 1 and 2 omitted on the narrow sides. Furthermore, the width of the heating element 10 can also be varied depending on the desired heat output, so that free areas on the longitudinal sides are made wider or narrower. Furthermore, the heating layer 7 may be divided into individual subfields.
    For example, the surface heating element 10 may be arranged between the gypsum core 5 and the cardboard layer 4 aligned on the room side after installation of the expansion plate 1. By this arrangement is to be expected with a delay-free space heating. It is advantageous if the gypsum core 5 to increase the thermal insulation additives, such as microporous particles, such as perlite, vermiculite, Blähgläser or foaming agent has.
    However, it would also be possible to arrange the surface heating element 10 between the gypsum core 5 and the rear cardboard layer 3 in order to exploit the storage effect and the heat distribution through the gypsum core 5. It may be advantageous in this case if the gypsum core 5 has additives, for example graphite, carbon fibers, graphene, carbon nanotubes or other materials which improve heat conduction, to increase the thermal conductivity.
    The surface heating element 10 can either be arranged according to FIG. 1 on a carrier film 8 which simultaneously serves as a barrier layer or-particularly advantageously-fixed on the inner surface 9 of the cardboard layer 4 facing the gypsum core 5, for example glued or printed on (see FIG 2), wherein previously on the inner surface 9, the intermediate layer 13 is applied. For example, the heating layer 7 can be printed on the intermediate layer 13 on the inner side 9 of the cardboard layer 4 and an electrically conductive film strip can be bonded as a connection electrode 6 on both sides of the heating layer 7 with a conductive adhesive.
    Also in the variant according to FIG. 2, a further intermediate layer 19 (dashed and transparent indicated) may be provided to serve as a barrier layer between the heating layer 7 and the gypsum core 5. The further intermediate layer 19 may be printed on the heating layer 7 of the surface heating element 10, sprayed or laminated as a film.
    The heating layer 7 is preferably formed in a strip or net shape between the connection electrodes 6 and has diffusion-open zones of any geometry (circles, squares, triangles, diamonds, etc.) which, for example, form a regular pattern and whose total area is preferably greater than the total area of the Resistance material of the heating layer 7. This contributes to the fact that the plasterboard can dry out more quickly during production.
    In the inventive expansion plate according to FIGS. 1 and 2, the surface heating element can be supplied practically "endlessly" by a roller directly in the production process for plasterboard.
    The electric surface heating element 10 can also be arranged outside on a plasterboard 2 according to an embodiment variant shown in FIG. In this case, the surface heating element 10 is arranged on the outer surface 12 of one of the two cardboard layers 3, 4 and covered by a cover layer 14, for example of a nonwoven material. The heating layer 7 may be subdivided into individual heating fields, which are each applied to a partial surface of the intermediate layer 13, for example printed.
    According to the production method outlined in FIG. 4, first a lower board web 3 '(which forms the cardboard layer 3 in the finished removal board) is fed by a reel A and a gypsum compound is applied and evenly distributed in the position G. Thereafter, from a roll B, a second board web 4 '(which forms the cardboard layer 4 in the finished expansion board) is applied, on the inside 9 of which the intermediate layer 13 and the surface heating element 10 consisting of the heating layer 7 and the terminal electrodes 6 have already been printed. The second board web 4 'can be applied without changes to the existing device together with the intermediate layer and the surface heating element 10 in one step on the still soft gypsum core 5. Thereafter, the expansion plates 1 are cut in the position S and then dried. The heating layer 7 on the second board web 4 'can also be covered with a further intermediate layer 19 (see FIG. 2) in order to protect the heating layer 7 from direct contact with the gypsum core 5.
    The surface heating element 10 may similarly be laminated on the outer surface 12 of the board web 4 ', glued or printed, wherein in the same operation, a cover layer 14 (see FIG. 3) is applied.
    Without major changes to existing systems for the production of plasterboard, the surface heating element 10 can also be applied by means of a carrier film 8 or the intermediate layer 19, which is supplied from a separate role.
    The intermediate layers 13 and 19 and possibly the heating layer 7 have, at least in subareas, evenly distributed passage openings in the form of a perforation, so that the two layers are permeable to water vapor. As a result, the expansion plate 1 dry out evenly on all sides in the manufacturing process, so that the individual steps and processes in a conventional apparatus for the production of plasterboard must be adapted only slightly.
    The expansion plate 1 may have on the outer surface 12 of the cardboard layer 4 an identification, for example a color code, which characterizes the heating power of the surface heating element 10. Preferably, the operation takes place in the low voltage range <48 volts. For example, the color green may indicate a 24 volt operation and the color red a 36 volt operation.
    Furthermore, according to the invention, a marking 11 can be arranged on the surface 12 of the expansion board 1, which makes the shape and extent of the inner heating layer 7 and the connection electrodes 6 visible. Thus, the mounting of the expansion plate 1 is facilitated, as can be selected for the screw areas that are outside the sensitive areas. For the electrical contacting of the lateral connection electrodes 6, exemptions 16 in the cardboard layer 4 can be produced on a narrow side edge 15 of an expansion board 1, which according to FIG. 5 expose the end region of the flat connection electrodes 6 or together with the laterally cut-in part of the cardboard layer 4 be folded up.
    Thereafter, this exposed area can be connected by a clamping, soldering or plug connection 17 to the power supply 18. In room-high expansion boards 1, this connection is preferably in the base area and is covered after production of the connections by a baseboard, whereby the electrical supply and control lines can be performed in the baseboard.
