Description

The invention relates to a functional and / or decorative body for producing a floor covering surface or a covering surface as well as to a method for producing this functional and / or decorative body. The functional and / or decorative body is multi-layered and / or executed at least in two parts. It contains thermoplastic binders for the cohesion of the several layers with each other / each other.

Laying techniques are known in which intermediate webs are loosely laid on the ground, e.g. serve to reduce unwanted noise pollution when walking on the floor covering. However, this technique is preferably used for coverings made of wood-based materials and especially for such coverings, in which the individual wood tiles are loosely laid, but form a large-scale composite by profile connections. In this type of flooring a final / subsequent jointing is not provided.

In addition, many floor coverings are known in the art, which are made of a thermoplastic granules. Also, the required double belt presses are known, with which one produces such floor coverings. For this purpose, only the pamphlets are DE 197 51 516 C2 and DE 10 2007 063 261 A1 called.

Furthermore, from the document DE 10 2010 005 068 A1 a floor covering is known, with a bottom of at least one layer of a thermoplastic material. The top of this flooring consists of flagstones that adhere to the bottom layer.

From the DE 20 2010 001 149 U1 Furthermore, tiles (floor coverings) are known which contain cork-based and therefore elastic underlay materials on the underside. Tiles are also known in which adhering to the flanks of the backing sheet is guided from the horizontal by 90 ° upwards and fills part of the later tile joints. However, it has been shown that due to the material properties of the cork an exact bend around the tile edges is only very limited feasible. Outbreaks of the material and inaccurate cut edges can hardly be avoided with the known technical devices. This results in a significant proportion of non-recyclable goods and leads to subsequent processing by further damage to the edges to additional waste. It has therefore begun to dispense with the edge coating and to leave it at horizontal supernatants, which indeed simplifies the production of tiles, but does not solve the problem of damage to the edges of the tiles, but rather amplified. Since after the laying of such tiles - again - a large joint gap must be filled with grout, again more volume of grout is needed. This makes the process considerably more expensive and, because of the larger joint volume, also leads to undesirable shrinkage problems of the filling compound during drying, as well as to longer drying times.

It is therefore an object of the invention to at least reduce the problems described, in particular to eliminate the mentioned negative influences on the installation.

The object is achieved with a functional and / or decorative body with the features of claim 1. Embodiment variants of this new functional and / or decorative body reveal the claims 2 to 8.

For the production of this novel functional and / or decorative body, a method with the features of claim 9 is applied according to the invention.

Claims 10 and 11 disclose inventive method for producing sheet-like mats or covering sheets, which functional and / or decorative body according to claims 1 to 8 have.

The use according to the invention of these functional and / or decorative bodies for producing a floor covering surface or a covering surface, e.g. on a floor screed or a laboratory bench, claim 12.

According to the invention, it is provided in particular that in the functional body and / or decorative body having at least one main body and an upper body, the material for the main body, which is a so-called underlay for the upper body, is not elastic but thermally deformable and is compressible material. This material is in principle such that it develops only insignificant restoring forces during a thermal and / or mechanical deformation, so that the generated shape remains.

According to a variant embodiment, it is provided that the material for the basic body contains fibers, threads and / or yarns which reinforce this body, in particular in the deformed body regions, wherein the fibers themselves are not thermoplastically deformable, but can easily be bent without significant restoring forces to develop. Particularly suitable for this purpose are fibers, threads and / or yarns of natural materials or other non-thermoplastic materials or those which have a predominant volume fraction of Natural fibers, for example, a certain proportion of longer wood fibers.

According to one embodiment, the lengths of the fibers, threads and / or yarns vary between 1 cm and 5 cm, the quasi-diameters between 0.01 mm and 5.0 mm, advantageously between 0.1 mm and 2.0 mm. The lengths or diameters may also exceed or fall short of these values.

According to a further embodiment, it is advantageously provided that the thermally deformable and compressible material for the main body contains a proportion of thermoplastic fibers, which melt in the production of the body, ie during the thermal compression of its starting materials to an initially web-shaped body, ie when heated and create a kind of composite matrix.

According to the invention, it is additionally provided that these fibers can also be completely or partially replaced by one or more corresponding polymer powders or by one or more polymer dispersions; For example, to materials such as polyolefins, polyester or similar. Materials are used.

An essential advantage of the invention is that the resistance of the compacted web, ie the resistance of the backing layer against bending around the edge of the upper body considerably by the existing in the base body, ie in the backing layer for the upper body of the functional and / or decorative body long fibers non-fusible strengthened. In the experimental bodies manufactured and tested by the inventor and the Applicant, after the deformation process, the deformed structure remains without internal stress and maintains the set dimension with respect to the direction and the thickness. This is a result which was not to be expected according to prevailing technical teaching, thus surprising and confirming the basic idea of the invention. Advantageously, the volume fraction of non-meltable long fibers based on the total volume of the body, so the underlayer for the upper body is relatively high, preferably this volume fraction, depending on the material composition of the material for the body, between 20% and 90%.

In the functional and / or decorative body according to the invention, it is readily possible to use conventional cutting devices and transport aids right through to the packaging, without any injuries to the edges of the upper body, e.g. of tile edges, arise.

As is known, the dimensional tolerances of ceramic tiles, ie an upper body for a functional and / or decorative body according to the invention, are rather large. With the invention will give the publisher the opportunity, the positioning of functional and / or decorative body, so the so-called single tiles, or the positioning of multi-functional and or decor bodies existing sheet-like mats or consisting of several functional and or decorative bodies covering tracks to the extent necessary to produce a straight joint image.

When laying floor coverings or floor mats or floor tiles or stoneware with a lower layer according to the prior art, this is due to the elastic behavior of the lower layer, which also cover at least partially the side surfaces of the floor tiles or the stoneware in some product variants or form lateral projections hardly possible, especially with cork-containing supernatants.

This shows a significant improvement by the described invention, because the material is sufficiently compressible even after compression, and e.g. a deformation virtually no restoring forces opposes.

Another core idea of the invention is that the body receiving the upper body consists of a moisture-absorbing and / or moisture-conveying material or has such materials. These materials are according to one embodiment thermoplastic non-deformable, but easily bendable fiber, threads and / or yarns of the type already described above.

As a result, as a further advantage of the invention over known, an improvement in the drying times of the joints is achieved; in particular by the absorbency of said fiber, yarns and / or yarns or the like materials for water. The parts of the body that are substantially perpendicularly upright in the joints can, in contrast to non-absorbent materials, such as e.g. the aforementioned cork-containing material in floor tiles or stoneware according to the prior art, provide by capillary water transport for rapid drying of the joint material, which usually consists of an aqueous dispersion of plastic. The relatively small amounts of water are distributed capillary large area under the tiles on the lower layer according to the invention and discharged over the edges of the total area. This also local water inclusions are avoided and also residual moisture from the mounting surface, for example a floor screed discharged.

Another, additional feature and advantage of the invention is a variant in which one or more fixing areas are incorporated in the underside of the base body, virtually the lower outer surface of the base body is a positioning surface. These areas are made of materials that have a self-adhesive surface or other properties that improve the adhesion. Such substances are available in great variety. They are usually thermoplastics, which receive the desired properties with appropriate additives. These additives may be plasticizers, extenders, copolymers, or polymers with high levels of friction-generating fillers are used.

These fixing areas are arranged either disordered or arranged in a grid.

Also flocked particles or materials that have velcro-like properties are possible. The spreading density of these particles can be adapted to the later weight per unit area of the top-side ceramic tile, the upper body, whereby the lighter the tile, the higher the spreading density should be. Alternatively, it is of course also possible to use a corresponding adhesively treated fleece, which is presented over the entire surface.

The dimensions of the materials and / or particles forming the fixing areas are matched to the predetermined final thickness of the compacted material, the basic body. It is advantageous if the final height of the particles does not exceed 80% of the material thickness in order to avoid a vertically continuous connection up to the upper body, because this can adversely affect the sound insulation properties.

With this embodiment, in which one or more fixing areas, so-called Fixierflecken are incorporated on the underside of the body, the positioning of the functional and / or decorative body, so the so-called single tiles, or the positioning of several functional and or Decor bodies existing sheet-like mats or made of several functional and or decor bodies covering sheets improved when laying.

The process for producing the functional and / or decorative body provided according to the invention is described below.

The product, the functional and / or decorative body, is produced in several successive process steps. For the production of a double belt press mentioned in the description is used. Thus, at the same time and continuously more functional and or decorative body can be produced efficiently.

In a first step, the adhesive, which later forms the Fixierflecken, in the form of granules in a predetermined distribution on a lower conveyor belt, on a lower belt of the double belt press, scattered. It can be used a scattering template or the distribution is controlled in the usual scattering process on the spread rate.

Subsequently, in a second process step, the fiber mixture of thermoplastic and non-thermoplastic constituents is scattered in a predetermined initial thickness, ie over the granules already lying on the lower belt.

Alternatively, in the first method step, a premix of the said granules with the constituents of the intended fiber mixture in a thin layer can be sprinkled onto the lower band.

Alternatively, it is of course possible to facilitate later steps at this point insert a thermally activated adhesive fleece or apply a corresponding powder layer.

In a third process step, a thermal compaction of these multilayered scattered starting materials to a sheet-like body, which forms the body. Thereafter, in a fourth process step, on the obtained web, the formed web-shaped body, preferably the preheated upper body, e.g. Tiles, laid out so that between adjacent upper bodies longitudinal distances and transverse distances, ie, projections of the body arise.

Subsequently, the connection of the upper body with the web-shaped body takes place under the action of heat energy and pressure together with subsequent cooling.

In the further course of the manufacturing process, the multilayer bodies produced are separated from each other, taking into account the desired supernatant supernatants. The separation is preferably carried out with longitudinal and transverse cutters, the intermediate spaces are separated centrally. Thereafter, the multilayered bodies are separated.

The then still protruding edges of the body, the supernatant, are then in two successive steps, with intermediate rotation by 90 °, Pressed by means of heated rollers or skids on the flanks and fixed with subsequent cooling rollers.

So, first, a high-pressing the supernatant supernatants of the body to longitudinally arranged side surfaces of the upper body is carried out to a predetermined thickness. Subsequently, the multilayer bodies are rotated by 90 ° and then there is a high-pressing of the other supernatant supernatants of the body to the other side surfaces of the upper body to a predetermined thickness.

Finally, the transfer of the finished functional and / or decorative body to a follow-up process, e.g. the packaging.

According to one exemplary embodiment of the invention, in a modified / adapted production method, web-shaped mats or covering webs are produced from functional and / or decorative bodies according to the invention, preferably using a double-belt press.

First, ie in a first process step, a wide-meshed scattering of thermoplastic granules on a sub-belt of the double belt press is also carried out, for the production of fixing spots during the process step for the connection of the starting materials.

Subsequently, a fiber and / or substance mixture containing thermoplastic material is scattered onto the scattered individual granules.

Thereafter, the thermal densification of these multilayered scattered starting materials to a sheet-like body, which forms body. Subsequently, the laying of the upper body on the previously produced web-shaped body, wherein between adjacent upper bodies longitudinal distances and transverse distances are, and the subsequent connection of the upper body with the web-shaped body under the action of heat energy and pressure, followed by cooling.

In a further method step, the separation of the produced web-shaped body into a plurality of web-shaped mats or covering webs of predetermined area size takes place, taking into account the desired underlay protrusions on their peripheral multi-layered bodies.

In a next process step, the obtained web-shaped mats or covering webs are separated.

Subsequently, the suppression of the supernatant supernatants of the lateral base body to longitudinally arranged side surfaces of the upper body of the edge-side multilayer body is carried out to a predetermined thickness. Thereafter, the web-shaped mats or covering sheets are rotated by 90 ° and
then the other supernatant supernatants of the lateral base body to the other side surfaces of the upper body of the edge-side multilayer body pressed up to a predetermined thickness.

At the end of this production process, the transfer of the finished, functional and / or decorative body having sheet-like mats or the covering sheets takes place to a follow-up process, e.g. the packaging.

For this, just described embodiment of the manufacturing process according to the invention, a sub-variant is still provided. In this sub-variant of this manufacturing process, a double belt press is also used, it differs from the manufacturing method described above in the first three steps. In this manufacturing process, in a first method step, first of all, the application of the upper body to a lower band of the double-belt press takes place, with longitudinal spacing and transverse spacing between adjacent upper bodies.

In a second process step, a fiber and / or substance mixture containing thermoplastic material is scattered onto the upper body.

In a third process step, the wide-meshed scattering of thermoplastic granules on the layer of fiber and / or mixture, which in the subsequent process step for thermal compression of superposed starting materials and for connecting the upper body with the thermoplastic material of the sheet-like body under the action of heat energy and pressure to the fixation patches.

The further process sequence of the production process according to this sub-variant is the same as the corresponding process steps of the previously described embodiment variant of the production process.
