Description

DESCRIPTION

Floor covering plate and floor structure

The invention relates to a floor covering plate according to the general concept of claim 1 and a floor structure according to the general concept of claim 10.

A floor covering consisting of individual panels that are bonded together without glue is called a laminated panel. Wood fiber boards, plastic core boards, mostly PVC, or gypsum fiber boards, are usually provided with a top coating, either synthetic resin or lacquer based. The edges of the panels are provided with the corresponding tongue and groove profiles that fit without forming joints or almost without forming joints. The corresponding gypsum fiber boards are known, for example, from DE 202005020617 U1.

The disadvantage of the known panels is that the panels undergo changes in their shape, when they are subjected to a variable humidity, it also refers in this case to changes in shape with ambient humidity and / or temperature or that they lose resistance under the action of humidity permanent. The change in shape is so great that the profiles, that is, the joints between the profiles open as a result of high compressive and / or tensile stresses or, alternatively, bulge and rise from the substrate. This means that the floor covering is no longer level and closed, posing an aesthetic and functional problem. If gypsum fiber boards are exposed to moisture for a longer period of time, they lose their strength and therefore suffer a total loss of function.

In EP 3144 449 A1 and WO 2004/110748 A2 a construction element with a compressed mineral wool support is also known. A fiber cement panel that can be used as a construction element for floor, wall or ceiling panels, for example, is described in DE 10 2014 002 154 A1. These construction elements are difficult to process due to their compact design and material hardness.

In addition, it is difficult to join the components to form a surface using adhesive-free locking profiles, since the material makes exact profiling on the one hand, and assembly on the other, much more difficult compared to the materials used. wood base. Finally, both in document EP 3144449 A1 and also in EP 151207 A1 the corresponding locking profiles are disclosed.

Another type of floor covering plate is known from WO2013 / 179260 A1, which shows support plates of a thermoplastic base material. To compensate for the strong expansion movements of the base material during temperature fluctuations, several additional substances are integrated into the support plate in the form of fiber.

Therefore, the invention is based on the task of providing floor covering plates for a floor covering that do not react to temperature or humidity fluctuations with dimensional changes and retain their function even under prolonged humidity. Its technical properties allow for easy manufacturing, processing and assembly.

The task of the invention is accomplished by means of a floor covering plate with the characteristics of claim 1 and a floor structure with the characteristics of claim 10. Advantageous further developments of the invention are indicated in the secondary claims.

The floor covering plate according to the invention features a backing layer comprising compacted mineral wool on a mineral fiber plate and a binder, in which the mineral wool contains rock wool fibers and / or mineral wool fibers. glass and the support layer is configured with profiled edges for connection with a second identical floor covering plate, a first positive locking element being arranged on one side of the support layer and a second positive locking element on one side Opposite of the support layer and the two positive locking elements are configured in a complementary way with each other, so that the first positive locking element of the floor covering plate can be positively connected with the second locking element positive of another floor covering plate and is coated with the support layer, the covering in particular being an inseparably applied decorative layer e on the support layer forming the visible top side of the floor covering plate, in which additives from the group of polypropylene, polyethylene, paraffin or wax were added to the support layer and the coating adhered on the layer of support by adhesive bonding.

By means of the invention, problems caused by dimensional fluctuations in floor coverings, especially when installed as floating floors, are avoided and functionality is ensured even when exposed to moisture.

The backing layer is shaped like a backing plate due to compaction and binding agent, and preferably consists of non-hygroscopic materials such as mineral wool. Furthermore, and in combination with at least a large part of the non-hygroscopic materials (mineral wool), those materials that show little or no variation in their dimensions in the case of humidity or fluctuations in ambient humidity and / or may also be preferred. in temperature, and therefore are dimensionally stable. The support plate (or support layer) can be described as dimensionally stable, in particular, if under climatic fluctuations of 5 ° C to 40 ° C and 5% to 95% of relative ambient humidity, it presents a dimensional change (length, width , height) not more than 0.1% or, preferably, not more than 0.05% and preferably 0%, that is, it does not undergo a dimensional change.

Mineral wool is an inorganic substance, especially glass or rock wool. Mineral wool is defined as the mineral fibers associated with a wool, that is, the glass wool fibers and / or the rock wool fibers. Mineral wool is characterized by the fact that the fibers that form it are arranged in a non-directional and loose way, so that there are numerous spaces, usually filled with air, between the fibers. Uncompacted mineral wool, which is used, for example, as an insulating material, usually has a maximum density of approximately 220 kg / m3

A mineral wool plate is therefore a mineral wool composed of glass wool fibers and / or rock wool fibers, which is highly compressed and is held in the compressed (plate) form due to the binder. Therefore, the mineral wool plate comprises only a small number or volume of spaces between the mineral wool fibers and has a particularly high proportion of mineral fibers (glass wool fibers and / or rock wool fibers) arranged to form a wool. The mineral wool plate described herein is also referred to as a mineral fiber plate, so a mineral fiber plate described herein always refers to the mineral wool plate described above.

In this context, fibers are understood as particles having a length-to-thickness ratio of at least 1:10, preferably at least 1:20, especially preferably at least 1:30, advantageously at least 1:40 and Especially advantageous mode at least 1:50. Since mineral wool generally, in addition to fibers in the aforementioned sense, also comprises mineral particles with a length-to-thickness ratio of less than 1:10, in the context of the invention a mineral fiber plate is understood to be a plate of support in which at least 80%, preferably at least 90%, especially preferably at least 95% of the mineral particles in the support plate are fibers according to the aforementioned embodiment. The higher the proportion of fiber, the more stable the plate is and the less it reacts with changes in its measurements, when temperature fluctuations and / or humidity fluctuations occur.

It should be noted that the fibers of the mineral fiber plate are predominantly made of very fine material, so that the fibers preferably have a maximum length of up to 30 mm, advantageously a maximum length of up to 20 mm, preferably a maximum length of up to 15 mm and especially preferably a maximum length of up to 10 mm, in each case maintaining the aforementioned length-thickness relationships.

The use of mineral wool in the form of plates for the backing layer results in a very stable backing layer with the advantageous thermal and acoustic insulation properties, fire protection properties and waterproof properties of the mineral fibers that form the mineral wool. . For example, the mineral wool plate (mineral wool support plate) can be a rock wool or glass wool plate known in the construction sector for its thermal insulation, which is compacted and reinforced by a binder. In addition to glass wool and rock wool fibers, the binder is, as far as possible, temperature and moisture stable.

Rock wool and glass wool fibers can also be used in blends. It should be noted that, in relation to the invention, glass wool and rock wool are understood to be material that is at least largely non-hygroscopic and of stable dimensions according to the aforementioned definition.

In order to quickly and easily compose a complete floor covering with individual floor covering plates, the floor covering plates preferably have positive locking elements. Thus, it is preferably provided that the support layer has on one side, in particular on a longitudinal side, a first positive locking element. A second positive locking element is configured on the opposite side of the support layer. The two positive locking elements are mutually complementary. Then two of the floor covering plates are placed next to each other, so that the first positive locking element of the first floor covering plate is inserted into the second positive locking element of the second covering plate. of soil. In this way, the floor covering plates can present, for example, classic tongue and groove profiles.

In a rectangular shape of the floor covering plate, the positive locking elements are preferably arranged on opposite longitudinal sides. Alternatively, these can also be arranged on the transverse sides (short sides) of the support layer or complementary positive locking elements are provided on the longitudinal and transverse sides in each case. In the arrangement of the positive locking elements, the positive locking elements arranged on opposite sides are configured in a complementary manner, whereby identical complementary pairs can also be arranged on the longitudinal and transverse sides.

Floor covering plates with at least two outer edges of locking elements positive, for example profiled elements, are also called panels.

The support layers, in particular the support plates, to be used as panels (i.e. support layers / support plates with connecting profiles (positive locking elements) on the side edges) for floor coverings (coverings soil), must have optimal properties with respect to their technical properties. In particular, the high maximum internal shear forces and the resistance to separation must be guaranteed, so that an elastic joint profile can be milled. A value of 1 N / mm2 is proposed as adequate transverse tensile strength vertically and horizontally to the panel. Depending on the embodiment of the joint profile, a transverse tensile strength from 0.5 N / mm2 vertical and horizontal with respect to the plate is also possible. But due to the humidity and temperature resistance properties according to the invention present in the floor plate, these high transverse tensile forces are not necessary, since no residual stresses and changes in dimensions occur. Preferably, the panels are connected to each other to form a floor covering only by corresponding interlocking profiles (complementary positive locking elements). This floor covering is preferably floatedly placed by panels according to the invention. Preferably, the auxiliary means for fastening or connecting the panels, such as clamps, hooks or bolts, are dispensed with.

The support layers (in the form of plates) (also called support plates) are coated, that is, a separate coating was provided on at least one of the main external surfaces of the support layer. The liner is in particular inseparably attached to the backing layer, that is, it cannot be separated from the backing layer without its destruction. The covering comprises at least one decorative layer, which in the state of use of the floor covering plate is visible to the user who steps on the floor covering plate. The decorative layer, therefore, forms the visible surface of the floor covering siding layer. The decorative layer comprises, in particular, colors, patterns and / or structures that form the color decoration and, if appropriate, also a haptic decoration. In that case, the decorative layer may show, in particular, wooden, stone, tile or fancy decorations.

The support layer particularly preferably consists exclusively of a single support layer or several overlapping (and preferably fixedly attached) support layers.

The density of the support layer (eg of the mineral fiber plate, mineral wool plate or support plate) is preferably at least 600 kg / m3, in particular at least 925 kg / m3, especially preferred of at least 1,100 kg / m3.

To produce the support layer, in particular a mineral wool plate, a mineral fiber is moistened or soaked with the binder and a mineral wool is produced. If necessary, the mineral wool is pressed under heat, that is, it compacts and the binder ensures that the compacted shape is maintained. The pressing is preferably carried out in the form of a plate, so that the support layers are also called support plates.

As a binder, for example, a thermosetting plastic or plastic resin, especially phenoplastic, can be used. Possible binders can be phenolic, epoxy, melamine and / or ureic resins or biologically based crosslinking resins or the like. The binders can be used as liquid or solid binders, in powder and / or granular form. For example, a powdered and / or granulated binder, for example a phenolic resin, is particularly suitable for mixing with the mineral fibers and dispersing to form a mineral wool and then pressing to form a mineral wool plate.

In particular, mineral binding agents such as gypsum, cement, magnesia or the like are not suitable for the floor covering plate in the sense of the invention, since they do not exhibit sufficient dimensional stability in case of humidity fluctuations and / or temperature, they do not exhibit the necessary elasticity of the floor covering plate and are not suitable for chip release machining of positive locking elements.

One of the aforementioned binders (plastics, synthetic resins) can be used alone or mixtures of binders can be used. The proportion of the binder is from 4% by weight to 25% by weight, preferably from 5% by weight to 20% by weight, especially preferably from 6% by weight to 15% by weight and advantageously from 6% by weight at 12% by weight. The proportion of the binder used will be determined by the specialist in simple tests in relation to the requirements of the purpose of use.

Correspondingly, the proportion of mineral wool (fibers include particles not previously defined as fibers) is from 75% by weight to 96% by weight, preferably from 80% by weight to 95% by weight, especially preferably from 85% by weight to 94% by weight and advantageously from 88% by weight to 94% by weight.

In addition to the mineral wool and the binder, the backing layer may optionally contain bulking agents. Annual plant fibers like cotton, flax or ramie can be used as bulking agents. Optionally they can be treated hydrophobically. Hydrophobically treated grass fibers may also be used, such as bamboo or hydrophobically treated wood fibers or chips. Flours or granules are also possible, for example from cork or coconut shells. In principle, all cargo agents come into consideration resistant to humidity and temperature, since they are used, for example, in the production of glues and lacquers, for example calcium carbonate is mentioned.

The proportion of the bulking agent is preferably not more than 25% by weight, preferably not more than 15% by weight, advantageously not more than 10% by weight, in particular not more than 5% by weight. Mixtures of the aforementioned fibers and bulking agents may also be used in each case. When bulking agents are used, the proportion by weight (wt%) of mineral wool in favor of bulking agents is predominantly reduced. Correspondingly, the above-mentioned% by weight of the mineral wool is reduced by 1: 1 in the respective% by weight of the added bulking agents.

Bulking agents are preferably used to fill microscopic gaps between the mineral wool fibers and / or microscopic gaps between the fibers and the binders. When the bulking agent is used, the proportion of mineral wool should preferably be at least 50% by weight, advantageously at least 60% by weight, preferably at least 65% by weight, especially preferably at least 71% by weight, advantageously at least 81% by weight and especially advantageously at least 86% by weight

The bulking agent can be mixed with the glass and mineral wool fibers (mineral wool) or placed as a separate layer on the support layer, in particular the support plate. The rock wool and / or glass fibers and, if appropriate, the fillers are wetted together or separately with the binder, if appropriate mixed or laminated and formed into a support layer, for example pressed.

In addition to bulking agents, additives can also be used to improve the technical properties, processability, or haptics of the rear floor covering plate. These are added in reduced amounts of in total between 0.5% by weight and 1.5% by weight, preferably between 0.5% by weight and 2.5% and improve the technical properties of the support layer, such as For example, the elasticity, chip release properties and processability during mounting of the floor covering plate. As additives, for example, polypropylene, polyethylene, paraffin, wax or the like may be added, in particular wax and / or paraffin being added to bind especially small and short mineral particles in the mineral wool or at the protruding end of the mineral fibers, with which achieves a smoother haptics of the surface of the support plate and a better processability thereof. The weight ratio of the additives used is primarily at the expense of the weight ratio of the mineral wool, so that the mineral wool ratio is adjusted as much as possible to 1: 1 when the additives are used. With further use of the bulking agent, the weight ratio used may also be at the expense of the weight ratio of the bulking agent or at the expense of the weight ratio of the bulking agent and mineral wool.

By way of example, an advantageous support plate has the following composition: 5% by weight to 12% by weight of binder, 2% by weight to 10% by weight of bulking agents, 0.5% by weight at 2, 5% by weight of additives, 92.5% by weight to 75.5% by weight of mineral wool.

As explained before, the different floor covering plates have positive locking elements, which in each case comprise a first and a second positive locking element that are configured differently, but complementary, and are designed for mounting Quick and easy from floor covering plates to form a complete floor covering. The positively locking elements are particularly preferably configured for bonding without the use of adhesives. For this, the positive locking elements in particular may have been shaped as latch profiles, pivoting profiles and / or rotating profiles.

Otherwise, it is preferably provided that the first positive locking element and / or the second positive locking element are an integral component of the support layer. In accordance with this advantageous conformation, the respective positive locking element is not inserted as a separate part in the support layer, but is an integral component part of the support layer and is therefore composed of mineral fibers including binder and, if appropriate, bulking agent and additive.

Additionally or alternatively, at least one of the two positive locking elements may comprise for example a spring (spring-like component) as a separate component element acting on the complementary positive locking element or on the support plate.

Particularly preferably, provision has been made for at least one of the two positive locking elements to be produced by subsequent machining, for example milling of the support layer (support plate). Additionally or alternatively, it is provided that the first positive locking element and / or the second positive locking element is an element that is at least in sections originally formed in the support layer. The term "formed primary element" means that the respective element is not produced by subsequent machining of the support layer, but is already produced during the forming and pressing of the support layer. This means, for example, that it is not necessary to re-mill the groove for a tongue and groove in the support layer. Rather, the groove is already originally formed, that is, during the manufacture of the support plate. Accordingly, the first positive locking element preferably has an extension and the second positive locking element a slot. A prolongation is understood as a projection / elevation that shaped to insert into the slot at least in sections.

The inseparable bond (that is to say, that cannot be separated without destruction) between the lining and the support plate is made by means of an adhesive bond, that is, the decorative layer on the glued support layer. Of course, other layers, such as adhesion enhancement layers, may also have been arranged between the decorative layer and the backing plate, which also cannot come off without destroying them, so adhesion means not just a bond. direct to the surface of the support layer, but also an indirect adhesion of the decorative layer, namely on intermediate layers. Consequently, the decorative layer, for example, can also be multi-layered and, for example, can have its own backing layer, which carries the decorative layer, for example, a decorative paper.

For example, laminates based on synthetic resins can be pressed (glued), which are provided with a decoration and / or with a three-dimensional structure (structural decoration). Coatings with natural materials such as cork, patterned cork, veneer, in particular waterproofing veneer, leather, stone and / or wood are also possible. Coatings such as vinyl, linoleum, PVC (polyvinyl chloride) or polypropylene can also be applied. The decorative layer with the backing layer is preferably glued in a press, in particular in a heat press under the effect of heat. It is also possible to apply lacquered surfaces, liquid and cured synthetic resin surfaces or paints.

In addition to the aforementioned coating materials, a decorative print using ink, paint or lacquer can also be applied in various techniques, such as, for example, screen printing, intaglio printing or digital printing, which is provided with a transparent protective layer such such as, for example, a thermoplastic polyurethane film or a UV curing film or radiation cured acrylate.

Furthermore, a light protection film was preferably applied to the decorative layer to improve the light resistance of the decoration. Transparent protective layers can also be applied as a synthetic resin comprising a coating, a synthetic resin layer and / or a transparent lacquer layer.

Also known is laminating on short cycle presses with resin impregnated papers, such as those used in the production of laminate flooring, as well as coating with resin impregnated papers and sheets on continuous presses. In addition to resin-impregnated paper, resin-impregnated tiles such as, for example, fiberglass fleece or fabric can also be used as a coating. To increase mechanical properties, eg flexural strength, strength reinforcing layers can be applied on one or both sides such as eg technical reinforcing fibers such as glass, carbon fibers or aramid, as well as other fibers bonded with high resistance resin. These reinforced support plates can also be coated as mentioned above.

According to an advantageous embodiment, it is possible to manufacture a floor covering with a uniform decoration that is made from panels with known wood fiber support plates or chipboard panels in rooms without great influence of humidity or humidity. environmental or temperature fluctuation, while panels with the same surface in rooms with a high fluctuation of humidity or temperature are provided with a support plate according to the invention.

The manufacture of the floor covering plate can be carried out with the following steps and on the basis of the dry manufacture of fiber plates (MDF, HDF): manufacture of mineral fibers, in particular of glass fibers and fibers of rock, if necessary by mixing the fibers with additives and bulking agents, gluing the fiber / fiber mixture with an adhesive, for example a blow line, spreading the fiber / fiber mixture to form a fiber mat (mineral wool ), compression and / or pressing of the fiber mat to a support layer, if necessary under the influence of heat.

Manufacture is also possible with the following steps: manufacture of mineral fibers, in particular of glass fibers and rock fibers, dry mixing of the fibers with additives and fillers, dry mixing with powder resins, dispersion of the fiber / additive / resin mixture to form a fiber mat (mineral wool), compression and / or pressing of the fiber mat into a support layer, possibly under the influence of heat.

Furthermore, the task on which the invention is based is fulfilled by means of a flooring material comprising a base structure, preferably screed, and several floor covering plates placed adjacent to the base structure.

The composition of different floor covering plates to form a complete floor covering can be done in a simple way, since the support layer can be cut with a decorative layer with the usual elements. When using the floor covering plate according to the invention, an additional work step can be dispensed with to apply the usual insulating layers underneath the floor covering, since in the floor covering plate according to the Invention essential functions have been integrated, namely insulation, stiffness and decoration.

The designation used for the floor covering plate refers to floor covering plates that are placed adjacent to each other to create a complete floor covering. The floor covering plates are placed on a base structure to form the complete floor covering. The floor covering plates are therefore supported by their surface on the base structure. The base structure comprises, for example, the screed and additional insulation layers that can be used between the screed and the floor covering. In addition, the base structure comprises the static elements that support the load of the building. The floor covering plates or the composite floor covering of such plates is simply laid according to the required point and surface load and does not form a supporting element of the entire structure. Floor covering plates are understood, for example, to be panels that have positive locking elements on their outer edges, for example profiled. The positive locking elements are designed for the direct connection of the different floor covering plates or to help the connection of the different floor covering plates.

Hereinafter, the invention will be explained in greater detail by means of exemplary embodiments.

A typical first support plate, made according to the invention described herein as an example of embodiment, was made from rock wool fibers, it has a density of approx. 1,000 kg / m3 and is bonded with 10% by weight of phenolic resin as a binder. The proportion of rock wool is 90% by weight. According to an alternative embodiment, a second support plate further has a 2% polypropylene additive ratio. Thus, the proportion of rock wool fibers in the second support plate of 88% by weight. The plates in each case have a thickness of approx. 6 mm and have a dense surface. The first and second support plates are manufactured by mixing rockwool fibers and binder powder or in the form of granules, or rockwool fibers and polypropylene and binder in each case powder or granules, and spreading them to form a fiber cake; the fiber cake is then compressed in a press at temperatures of 140 ° C to 180 ° C and at a pressure of 5 N / mm2 to 25 N / mm2, preferably a pressure between 10 N / mm2 and 15 N / mm2 until the binder has hardened. Alternatively, glass wool fibers or a mixture of rock wool fibers and glass wool fibers can also be used.

On the support layer (in this case the support plates), in particular directly on the mineral fiber plate, the decorative layer is glued, especially inseparably. This can be done in a short cycle press in which, for example, the backing layer is coated with a laminate under the effect of pressure and heat. Inseparable is, for example, the junction between the decorative layer and the carrier layer. The decorative layer forms the visible upper part of the floor covering plate.

The laminate features decorative paper. The laminate is supplied with melamine resin as a synthetic resin, as known from panels with wood fiber carrier plates. As an option, a primer or base coat can be applied to the backing plate before applying the laminate.

The support plate is disassembled into individual pieces and is provided with a profile (positive locking element) on the edges so that the panels are formed. Thanks to the glue-free interlocking profiles, two interlocking panels are secured against displacement in height, i.e. at right angles to the plane of the panels, and also against separation, i.e. in one direction in the plane of panels. These profiles are known, for example, as panels with wood fiber support plates. The dust generated by fixing the profiles is extracted by suction and can optionally be recycled.

These panels can have any shape, but are generally rectangular. They can be joined at the longitudinal edges and at the transverse edges by means of the corresponding tongue and groove profiles, optionally and with the corresponding conformation of the profile, they can be detachably joined.
