  • Common rollable floor coverings consist predominantly of elastic or thermo-elastic material and thus offer a typically high level of walking comfort.
  • the surface properties of generic rollable floor coverings are limited in terms of scratch or abrasion resistance, so that such floor coverings are practically not suitable for object or industrial environments with heavy load.
  • Non-rollable floor coverings are usually realized in the form of plate-shaped, non-flexible plastic coverings, or in the form of wood coverings (parquet or laminate).
  • Not flexible plastic coverings structurally usually rollable homogeneous products, but are designed by high Gearstoffanteile or various intermediate layers rigid and dimensionally stable.

  • the stress compensation layer of the invention makes it possible to absorb any frictions that occur between the (typically paper-based) cover layer and the stabilization layer in a rolling process and, without compensation, either to buckling of the rigid body of the stabilization layer, which is usually realized as fibers, or else Upsetting or tearing the paper sheet, would lead.
  • the stress compensation layer comprises a polymer or a polymeric mixture which, to some extent, typically by means of suitable additives, enables a cold flow so that the stress compensation layer also has the character of a sliding layer.

  • the stress compensation layer is particularly effective when the material of the stress compensation layer at least partially penetrates or soaks through the stabilizing layer or its rigid body (ie in the preferred embodiment, in particular its fibers), so that, in addition to the described effect as a sliding layer, the stress compensation layer also has a mechanical fastening and gluing the layers causes and arise in the sequence of layers, the stress compensation layer and the stabilizing layer as a common layer and / or seamlessly merging layers.

Abstract

La présente invention concerne un revêtement de sol souple, notamment un revêtement pouvant être enroulé. Ce revêtement présente une couche de support (10) et une couche de recouvrement (14) qui se trouve sur la couche de support et qui offre une surface plane et/ou texturée. La couche de recouvrement (14) présente un film de papier ou de matière plastique pourvu d'un revêtement résistant à l'usure, constitué d'une résine durcissant aux rayonnements et de matières de charge abrasives. La couche de support présente plusieurs couches, une première couche de polymère (10) qui comprend des particules de charge, notamment des particules de bois et/ou de la farine de bois, ainsi qu'une couche de stabilisation (12) qui est formée sur la couche de polymère dans la direction de la couche de recouvrement et qui est conçue pour augmenter la résistance mécanique de la couche de polymère au moyen de corps rigides, en particulier au moyen de fibres de verre et/ou de fibres de matière plastique. Une couche d'égalisation de tension (12) est placée entre la couche de polymère et le film de papier ou de matière plastique, notamment entre la couche de stabilisation et le film de papier ou de matière plastique. Cette couche d'égalisation de tension est conçue de manière à compenser avec les corps rigides une contrainte mécanique exercée sur le film de papier ou de matière plastique lorsque le revêtement de sol est plié.
