  • the linoleum or corkment based base layer of the sheet of the present invention can be made by conventional static (e.g., presses) or dynamic (e.g., roll) processes for making single or multi-layer linoleum or corkment sheet, with or without backing. Accordingly, the processing of linoleum or Korkment- cements, which are made according to the requirements of DIN EN 548 or DIN EN 12455 from drying vegetable oils or fats and tree resins.
  • the base layer of linoleum of the fabric according to the invention can be provided with or without support.
  • the base layer of linoleum or corkment is provided with a carrier, first the base layer is laminated with the carrier. Subsequently, for example, the (UV-curing) adhesive layer is provided on the side facing away from the carrier of the base layer and the transparent cover layer is subsequently arranged on the adhesive layer.
  • the base layer of linoleum or corkment when the base layer of linoleum or corkment is provided without a carrier, according to the method of the present invention, for example, the (UV-curable) adhesive layer and then the transparent cover layer are arranged thereon.
  • the adhesive layer comprises a UV-curable adhesive which cures at two different wavelengths. This allows a two-stage curing of Adhesive layer.
  • the manufacturing method comprises the following steps:
  • the provision of the UV-curable adhesive layer may also be on both the base and top layers, wherein the bonding of the individual layers is then performed by placing the resulting partially cured UV-curable adhesive layers on each other and bonding the individual layers by curing the UV-curable adhesive layers are at a second wavelength.
  • the adhesion of the individual layers to one another can be further increased, since, owing to the first partial curing, the base layer and / or cover layer is already initially filled with the adhesive layer is connected and / or be connected by the separate second curing, the transparent cover layer and / or base layer with the other layers.
  • the UV-curable adhesive layer is merely gelled or pre-gelled, which on the one hand increased dimensional stability is achieved, and on the other hand, a pre-bond between the adhesive layer and the base layer and / or cover layer is produced, which surprisingly to improved adhesion resistance the individual layers with each other in the resulting inventive sheet leads.
  • the side of the base layer facing the cover layer and / or the surface of the transparent cover layer facing or away from the base layer can already be printed during its production or shortly before the arrangement is arranged with respect to the (UV-curable) adhesive layer.
  • either the surface of the optional further layer (white film) facing the cover layer may already be printed or printed with the transparent cover layer shortly before being joined.
  • this further layer is present in the sheet according to the invention, it is preferred that these layers, i. the further layer and the cover layer, as in the case of the base layer and the support, are already arranged in the form of a laminate, for example on the (UV-curable) adhesive layer.
  • a further protective layer in the form of a lacquer or finish is to be provided on the transparent cover layer, this layer can be provided thereon both before the covering layer is arranged on the (UV-curable) adhesive layer and after the adhesive layer has cured.
  • This additional protective layer can conventionally be applied to the cover layer by, for example, brushing, rolling, spraying or casting, preferably in a continuous process.
  • the present invention provides the use of a linoleum or corkment-based sheet as a wall covering, ceiling covering, floor covering, decorative cover or veneer. According to the invention, the use of the fabric based on linoleum or corkment is preferred as floor covering.
  • the sheet of the present invention may be in the form of a sheet or tile, for example.
  • the adhesive layer according to the invention makes it possible to combine a linoleum or corkment base layer with a transparent cover layer as a wear layer of a corresponding fabric.
  • This realizes advantageously on the one hand the partial use of renewable raw materials, the basis of linoleum and Korkment, and on the other hand, a great freedom and diversity in the design of the appearance of a corresponding fabric according to the invention based on linoleum or Korkment.
  • appropriate printing techniques can be used here for the design, which was previously not possible in combination with the material linoleum or corkment.
  • the sheet according to the invention is characterized by the absence of, for example, halogen-containing materials by its environmentally friendly properties, which are based not least on the resource-saving manufacturing process.
