Definitions
- the invention relates to PVC-based, layered floor coverings, and methods for the production of such floor coverings.
- PVC-based, layered floor coverings are already generally known.
- the floor coverings known to date have a number of possible drawbacks.
- the sound damping for continuous noise is not adequate, the floor coverings may possibly show a lasting imprint after point loading (for example by table or chair legs), and floor coverings that are not fully glued to the substrate tend to wrinkle if an object is slid over their surface. All of this is particularly the case if the floor covering is configured as a floor covering that is wall-to-wall, soft, and capable of being rolled up. These floor coverings should also remain flat after being unrolled, which is not always the case.
- An object of the invention is to provide a PVC-based, layered floor covering that is capable of achieving a good compromise with respect to the above-mentioned drawbacks.
- a PVC-based, layered floor covering comprising the following successive layers:
- a decorative layer comprising a polymer layer
- a wear layer comprising a transparent polymer layer
- the first PVC layer has a thickness of more than 2.0 mm, consists of foamed PVC and provides the underside of the floor covering.
- the thickness of the first layer is selected in the range of 2.0 mm to 3.5 mm, more preferably between 2.3 mm and 3.0 mm, for example between 2.4 mm and 2.6 mm .
- the density of the first PVC layer can be in the range of 0.25 to 1.00 g/cm 3 .
- the PVC of the first PVC layer preferably has a density of 0.30 to 0.80 g/cm 3 , such as 0.30 to 0.50 g/cm 3 .
- the PVC of the first PVC layer is foamed.
- a foamed layer refers to a layer that has hollow cavities, preferably in an amount such that the density of the material is reduced by at least 10%, and preferably even at least 25%, with respect to the weight of an equal volume of thermoplastic material without hollow cavities. Preferably, this is so-called closed cell foam.
- a non-foamed layer refers to a layer without hollow cavities, or at least, however, with a maximum proportion of hollow cavities such that the density of the material is not reduced, or is reduced by not more than 10%, and preferably even by not more than 2%.
- the PVC can be chemically or mechanically foamed.
- the foamed layer is obtained at least by means of a mechanical foaming process.
- a mechanical foaming process This means that cavities are formed in the layer in question by pressing out the thermoplastic material and replacing it with a gas (such as air), often under the influence of a mechanical action or by blowing in of a gas (such as air) under pressure.
- the foamed layer is obtained at least by means of a chemical foaming process.
- a gaseous reaction product for example, azodicarbonamide can be used.
- this substance releases nitrogen gas that remains present in the foamed layer in the form of bubbles.
- the foamed layer is obtained at least by means of fillers, wherein these fillers themselves comprise one or more cavities.
- these fillers themselves comprise one or more cavities.
- the PVC of the first PVC layer can be a soft PVC.
- the soft PVC of the first PVC layer comprises plasticizers, in an amount of 15 to 100 phr, and preferably in an amount of 30 to 100 phr, for example 50 to 80 phr.
- the plasticizers can include, inter alia, esters of carboxylic acids (for example esters of ortho- or terephthalic acid, trimellitic acid, benzoic acid and adipic acid), for example diisononylphthalate (DINP), dioctyl terephthalate (DOTP), di-isononyl-1 , 2-cyclohexane dicarboxylate (DINCH), esters of phosphoric acid, for example triaryl or trialkylaryl phosphates, for example tricresyl phosphate, chlorinated or non-chlorinated hydrocarbons, ethers, polyesters, polyglycols, sulfonamides, or combinations thereof.
- esters of carboxylic acids for example esters of ortho- or terephthalic acid, trimellitic acid, benzoic acid and adipic acid
- DINP diisononylphthalate
- DINP dioctyl terephthalate
- DINCH
- the PVC of the first PVC layer possibly also comprises fillers, such as glass fibers, calcium hydroxide (slaked lime), calcium carbonate and calcium hydrogencarbonate, and/or CaMg(CC>3)2, talc, or also lightweight fillers such as hollow microspheres (Expancel).
- the PVC formulation of this PVC layer can comprise fillers to between 10 and 50 wt%, preferably between 15 and 45 wt%, for example between 20 and 45 wt%.
- the above-mentioned percent by weight (wt%) is expressed as the weight of the filler with respect to the weight of the entire polymer formulation, in this case PVC, in which the filler is contained.
- this PVC can comprise additives such as pigments and dyes, preservatives, antifungal agents, thermal stabilizers, UV stabilizers, blowing agents, viscosity regulators, and the like.
- the PVC of the second PVC layer can be a soft PVC.
- the soft PVC of the second PVC layer comprises plasticizers, in an amount of 15 to 100 phr, and preferably in an amount of 30 to 100 phr, for example 30 to 60 phr. “Phr” stands for parts by weight of plasticizer per hundred parts by weight of PVC.
