    专利说明:

    The invention relates to a method for producing a covering element, in particular for attachment to a floor or a wall. Furthermore, the invention relates to a covering element, which is particularly suitable as floor and wall or wall covering.
    Covering elements for floors or walls are already known several times. For example, there are hard tiles made of clinker or ceramic materials. There are also flexible plastic floor coverings.
    The object of the invention is to provide a method for producing a covering element as well as a lining element, which has a high resistance to external influences, in particular against mechanical abrasion, against UV light, against heat and against aging. In addition, the covering element should create a visually appealing impression and in particular may have a stone-like surface structure.
    This is achieved by a method having the features of claim 1 or by a covering element having the features of claim 21.
    The basic idea of the invention is to mix a liquid polymer (preferably in the form of an aqueous dispersion) with cement and then apply this mixture to a preferably flexible support.
    In order to improve the adhesion to the support, it can be provided with an impregnating layer before the overlay is applied from the mixture of the liquid polymer with the cement.
    Preferably, the mixture of the liquid polymer with the cement in several layers one above the other is first applied flat, wherein between the individual applications drying or hardening times are scheduled. The uppermost layer of the support may then particularly preferably have a relief-like (eg stone-like) structure, which can be produced, for example, by mixing the mixture of the liquid polymer with the cement not flat but, for example, in a point or line (preferably irregularly) on FIGS The uppermost layer is then applied and then, for example, pressed down and smoothed with a smoothing trowel, whereby no full-surface structure, but rather a relief-like, stone-like structure arises.
    If dyeings are desired, either the coating layers can be dyed or an acid stain applied at the top.
    Further advantages and details of the invention will be explained in more detail with reference to the following description of the figures.
    1 shows the layer structure of an embodiment of a covering element according to the invention in a partially broken away view in order to better show the layer sequence.
    Seen from bottom to top, this figure 1 shows the Verfahrensschitte.
    FIG. 2 shows an exemplary embodiment of a surface of a covering element according to the invention.
    In the production of the covering element according to the invention, a carrier 1 is first started according to FIG. This is flexible according to a preferred embodiment and may, for example, be a textile fabric, such as a woven, knitted or knitted fabric. Preferably, this fabric is at least partially and more preferably entirely cotton, and thus a natural material which also has high absorbency for subsequent impregnation.
    The surface density of the flexible carrier material is between 200 g / m 2 and 500 g / m 2, preferably 300 g / m 2. On the one hand, these numerical values provide the necessary stability and, on the other hand, the desired flexibility. Namely, a particularly preferred feature of the invention consists in the fact that the floor covering element ultimately also remains flexible together with the layers applied according to FIG. 1. Thus, it can be rolled for transport and be used excellently even on non-flat surfaces, for example by sticking.
    In order to ensure the adhesion of the overlying layers to the flexible support 1 even when it is actually moved, in particular rolled, an impregnation 2 is preferably provided which at least partially penetrates into the material of the support. In particular, substances which contain hydrocarbon solvents, waxes, zirconium salts and / or paraffins are suitable as impregnations.
    A first layer of a mixture of a liquid dispersion of acrylic copolymers or EVA copolymers (preferably combined with modifiers) on the one hand and cement on the other hand is then first applied to the impregnated support 1, 2.
    As a cement is particularly suitable white Portland cement.
    The mixing ratio between Portland cement on the one hand and liquid copolymer on the other hand is preferably 40% - 60% cement and 60% - 40% liquid polymer. More preferably, the mixing ratio is about 60% cement and 50% liquid polymer (all figures are by weight).
    As a liquid dispersion of copolymers in particular the material POLYTOP of the Italian company Stone International S.r.l. or the product Liquid Polymer MT-3000 from Brickform.
    If desired, color pigments can be added to this mixture, it being advantageous to add liquid dyes to the liquid dispersion and to add powdered dyes to the cement before the mixing takes place.
    After application of the first sheet layer of this edition of the mixture of the liquid polymer with the cement, this is cured, the term "curing" is more concerned with the chemical bonding and should not express that a hard, rigid surface is formed. On the contrary, the layer remains flexible and can thus adapt to the shape of the flexible support 1. By impregnation is particularly well prevented that a detachment from the carrier 1 takes place.
    After a suitable waiting time, further laminar layers, for example two to three further laminar layers, are applied.
    Subsequently, the formation of a relief-like surface 3a in which the mixture of liquid polymer and cement pointwise or line by line (for example, using a spatula or a brush) is applied to the hitherto topmost layer. These drops or lines are then somewhat depressed with a trowel under normal pressure, so that a relief-like, but overall substantially smooth surface is formed. The relief height is relatively low. These reliefs 3a or texture of the surface can give a stone-like impression.
    On top of this relief structure, a color layer 4 (acid stain) can then preferably be applied, for example by spraying or wiping (washing technique).
    Finally, then a thin protective layer 5 can be applied from a transparent protective lacquer or wax, to better protect the surface against environmental influences.
    The covering element according to the invention can be produced over a large area and then cut together to form, for example, rectangular plates which can be easily laid. Of course, these (flexible) plates may have other shapes besides the rectangular shape, such as polygonal or round shapes.
    In FIG. 1, the individual layer thicknesses are shown exaggeratedly thick for illustrative purposes. In reality, the layer thickness of the entire covering element is preferably of the order of 0.5 mm to 3 mm, preferably between 1 mm and 2 mm.
