Decorated surface-structured wall or floor panel

Abstract

A decorated and surface-structured wall or floor panel comprises a carrier made of a plastic composite material, a primer layer disposed on a surface of the carrier, a decorative layer disposed on the primer layer, a layer of a radiation-curable varnish disposed on the decorative layer, a structured plastic film disposed on the layer of a radiation-curable varnish, and a topcoat layer disposed on the structured plastic film. The carrier comprises a plastic-containing matrix material in which a fibre mineral material is embedded.

DETAILED DESCRIPTION

(7) Example embodiments will now be described more fully with reference to the accompanying drawings.

(8) FIG. 1 schematically shows the structure of a decorated and surface-structured wall and/or floor panel 100 according to the disclosure. The panel comprises a carrier 110 preferably made of a plastic composite material. On a surface of the carrier 110 a primer layer 120 is disposed which also can serve as a printing subsurface for the decorative layer 130 disposed thereon. The decorative layer 130 can be applied onto the primer layer 120 by means of a direct printing process such as flexographic printing, offset printing or screen printing processes, and in particular by means of digital printing techniques such as inkjet processes or laser printing processes. On the decorative layer 130, in turn, a layer 140 of a radiation-curable varnish is disposed, by means of which the structured plastic film 150 disposed on the layer 140 is bonded to the layer composite. Above the structured plastic film 150, a topcoat layer 160 is disposed. It may be provided that the topcoat layer 160 comprises hard materials and/or solids and/or fibers for improving the wear resistance. In any case, the topcoat layer is designed such that it does not or not completely level out the surface structure caused by the structured plastic film, so that it is at least partially haptically perceptible at the surface of the wall or floor panel.

(9) FIG. 2 shows schematically an intermediate product 101, as can be obtained in the context of the method according to the disclosure. Here, the layers 110, 120, 130 and 140 correspond to the layers known from FIG. 1. Instead of an already pre-structured plastic film the intermediate product shown in FIG. 2 comprises a not or not completely structured plastic film 151. In an optional temporally and/or spatially separated further processing step, the surface of the intermediate product 101 formed by the plastic film can be structured by means of suitable embossing means, in particular under the action of heat. In a further optional temporally and/or spatially separated further processing step then a topcoat layer can be applied.

(10) FIG. 3 shows schematically an intermediate product 102, as can be obtained in the context of the method according to the disclosure. Here, the layers 110, 120, 130 and 140 correspond to the layers known from FIG. 1. The layer 152 represents a structured plastic film in the embodiment shown. It may either be an already pre-structured plastic film or a non-structured plastic film as shown in FIG. 2, which in an optional temporally and/or spatially separated further processing step has been structured by means of suitable embossing means, in particular under the action of heat. In a further optional temporally and/or spatially separated further processing step then a topcoat layer can be applied.

(11) The foregoing description of the embodiments has been provided for purposes of illustration and description. It is not intended to be exhaustive or to limit the disclosure. Individual elements or features of a particular embodiment are generally not limited to that particular embodiment, but, where applicable, are interchangeable and can be used in a selected embodiment, even if not specifically shown or described. The same may also be varied in many ways. Such variations are to be regarded as a departure from the disclosure, and all such modifications are intended to be included within the scope of the disclosure.
