Title: PLASTIC-CONTAINING SUPPORT FOR A DECORATED WALL PANEL OR FLOOR PANEL AND METHOD FOR THE PRODUCTION THEREOF
Abstract:
The present invention relates to a plastic-containing support (10) for a decorated wall panel or floor panel (18), comprising a supporting material (12) including a thermoplastic matrix material, in which a solid material with a particle size less than or equal to 800 µm is embedded, wherein the support (10) has a length (l), a width (b) and a thickness (d), wherein the support (10) has a density gradient along its thickness (d) from a bottom surface (14) to a top surface (16) arranged on the opposite side to the bottom surface (14) in such a manner, that the density of the supporting material (12) averaged over a specified width (b) or a specified length (l) of at least 5mm, preferably at least 20mm, from the bottom surface (14) to the top surface (16) initially declines and then increases again.
