Technical field

The invention relates to PVC-based, layered floor coverings, and methods for the production of such floor coverings.

Prior art

PVC-based, layered floor coverings are already generally known. The floor coverings known to date have a number of possible drawbacks. As is generally the case, 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.

Summary of the invention

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.

In accordance with a first aspect, a PVC-based, layered floor covering is provided, comprising the following successive layers:

a. a first PVC layer;

b. a layer of a first PVC permeated textile product;

c. a second PVC layer;

d. a layer of a second PVC permeated textile product;

e. a decorative layer comprising a polymer layer;

f. a wear layer comprising a transparent polymer layer;

wherein 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. Preferably, 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 .

In accordance with embodiments, 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.

In accordance with a first possibility, the foamed layer is obtained at least by means of 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.

In accordance with a second possibility, the foamed layer is obtained at least by means of a chemical foaming process. This means that cavities are formed in the layer in question by means of a gaseous reaction product. For example, azodicarbonamide can be used. On heating, this substance releases nitrogen gas that remains present in the foamed layer in the form of bubbles.

In accordance with a third possibility, the foamed layer is obtained at least by means of fillers, wherein these fillers themselves comprise one or more cavities. For example, one can make use of the expanded state of the above-mentioned microspheres. More particularly, one can make use of the microspheres known from WO 2013/178561. Or it can be obtained by using expanded granules in a PVC-based layer. In accordance with embodiments, the PVC of the first PVC layer can be a soft PVC. Preferably, 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. “Phr” stands for parts by weight of plasticizer per hundred parts by weight of PVC. 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.

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.

Furthermore, this PVC can comprise additives such as pigments and dyes, preservatives, antifungal agents, thermal stabilizers, UV stabilizers, blowing agents, viscosity regulators, and the like.

In accordance with embodiments, the PVC of the second PVC layer can be a soft PVC. Preferably, 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. 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. The PVC of the second 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 60 wt%, preferably between 15 and 45 wt%, for example between 15 and 35 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.

Furthermore, this PVC can comprise additives such as pigments and dyes, preservatives, antifungal agents, thermal stabilizers, UV stabilizers, blowing agents, viscosity regulators, and the like.

In accordance with certain embodiments, the PVC of the second PVC layer can be unfoamed. In accordance with other embodiments, the PVC of the second PVC layer can be foamed.

The PVC of the second 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 second PVC layer can be foamed in accordance with the methods described above. The foamed PVC of the second PVC layer can be foamed in a similar, identical or different manner compared to the foamed PVC of the first PVC layer.

The PVC of the second PVC layer can also be unfoamed, and then has a density of for example more than 1 g/cm ³ , for example between 1.2 and 1.9 g/cm ³ , such as 1.3 to 1.6 g/cm ³ .

Preferably, the thickness of the second layer is selected in the range of 0.2 mm to 2 mm, more preferably between 0.3 mm and 1.2 mm, for example between 0.4 mm and 0.8 mm .

Between this first PVC layer and this second PVC layer, a layer of a first PVC permeated textile product is provided. This first textile product is preferably a textile product comprising glass fibers, such as a glass fiber nonwoven or a glass fiber woven. Preferably, a glass fiber nonwoven is used, which preferably can have a surface weight of between 30 and 60 g/m ² and a thickness of between 0.20 and 0.45 mm, for example between 0.25 and 0.45mm.

In accordance with embodiments, the first textile product can be partially impregnated with the PVC of the second PVC layer and partially impregnated with the PVC of the first PVC layer, so that first textile product is permeated with PVC.

In accordance with embodiments, the first textile product can be completely permeated, and therefore permeated, with the PVC of the first PVC layer.

In accordance with embodiments, the first textile product can be completely permeated, and therefore permeated, with the PVC of the second PVC layer.

This permeation can be achieved during the production process for producing a floor covering in accordance with the second aspect of the invention. In accordance with alternative embodiments, the first textile product can be permeated with a PVC that is either identical to the PVC of the first PVC layer, identical to the PVC of the second PVC layer, or completely different from the PVCs used for the production of the first and second PVC layer.

The first PVC permeated textile product therefore comes into contact with the second PVC layer on a first side of the second PVC layer. Optionally, this first textile product is permeated by this second PVC layer.

On the second, opposite side of the second PVC layer, this second PVC layer is brought into contact with a second textile product, which is a part of a layer of a second PVC permeated textile product.

This second textile product is preferably a textile product comprising glass fibers such as a glass fiber nonwoven or a glass fiber woven. This second textile product can, but does not have to be, the same product as the first textile product.

Preferably, a glass fiber nonwoven is used for this second textile product that preferably can have a surface weight of between 30 and 60 g/m ² and a thickness of between 0.20 and 0.45 mm, for example between 0.25 and 0.45 mm. In accordance with embodiments, the second textile product can be permeated with the PVC that is either identical to the PVC of the first PVC layer, identical to the PVC of the second PVC layer, or completely different from the PVCs used for the production of the first and second PVC layer.

In accordance with embodiments, the second textile product can be permeated with the PVC that is different from the PVC of the first and the second PVC layer.

Preferably, a PVC is used for the permeation of the second textile product, more preferably a soft PVC. Preferably, a PVC with a density of for example more than 1 g/cm ³ is used, for example between 1.2 and 1.9 g/cm ³ , such as 1.3 to 1.6 g/cm ³ .

Preferably, this soft PVC 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.

Preferably, the thickness of the layer of the second with PVC permeated textile product is between 0.3 and 0.4mm.

The second PVC permeated textile product therefore comes into contact with the second PVC layer on a first side of the PVC permeated textile product. On the second side of the second PVC permeated textile product, this second PVC permeated textile product is brought into contact with a decorative layer.

This decorative layer comprises a polymer layer, typically again PVC, which has the purpose of determining the final outer appearance of the floor covering. A decorative pattern or motif can be applied to this polymer layer, for example with ink, such as waterproof inks. Optionally, this pattern or motif is not more than one uniform color other than the color of the polymer used. In an alternative form, the polymer is dyed in the mass.

Preferably, a PVC is used for the provision of the decorative layer, more preferably soft PVC. Preferably, a PVC with a density of for example more than 1 g/cm ³ is used, for example between 1.2 and 1.9 g/cm ³ , such as 1.3 to 1.6 g/cm ³ . Preferably, this soft PVC 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. In order to make the layer opaque or white, this PVC layer preferably comprises Ti02, preferably larger amounts of Ti02.

In accordance with embodiments, the polymer of the decorative layer can be PVC.

In accordance with embodiments, the polymer of the decorative layer can be foamed PVC.

In accordance with embodiments, the polymer of the decorative layer can be unfoamed PVC.

Preferably, the thickness of the decorative layer is between the 0.1 and 0.6 mm, for example between 0.15 and 0.25 mm.

On the side opposite the side of the decorative layer that comes into contact with the second textile product permeated with PVC, a wear layer is provided.

This wear layer comprises a transparent polymer layer, again preferably transparent PVC.

In accordance with embodiments, the polymer of the wear layer can be PVC.

Preferably, a PVC with a density of for example more than 1 g/cm ³ is used, for example between 1.1 and 1.6 g/cm ³ , such as 1.15 to 1.35 g/cm ³ .

Preferably, this soft PVC 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. Preferably, this PVC layer is not filled, and therefore comprises no fillers.

Preferably, the thickness of the wear layer is between 0.1 and 0.7 mm, for example between 0.35 and 0.55.

Possibly, on the wear layer, on the side that does not come into contact with the decorative layer, another lacquer layer can be applied. This lacquer is preferably a polyurethane (PU) lacquer, with a surface weight of preferably between 10 and 30 g/m ² , and a thickness of between 10 and 30 pm.

The floor covering in accordance with this first aspect of the invention has a number of advantages. The floor covering can be rolled up, i.e. can be provided on a roll, for example a roll 2 to 4 meters in width and for example up to 20 or 30 meters in length, but behaves as a flat surface once it is unrolled onto a flat substrate. It remains dimensionally stable and shows little or no wrinkle formation when objects, for example furniture, are slid over the surface, and this without gluing the floor covering to the substrate. The floor covering also provides an improvement in contact sound insulation ALw of 20 dB: this is the sound damping for continuous sound.

Fig. 1 schematically shows a production method for producing a floor covering in accordance with the invention. A first textile product, for example a glass fiber nonwoven 1 10, is unrolled and supplied to a first station 120 for the application of a first PVC plastisol 122. By means of a doctor blade 124, the plastisol is pressed into the nonwoven, so that a textile product 130 permeated with PVC plastisol is obtained. The plastisol 122 is pregelled at a first drying station 140.

On a first side of the permeated textile product 130, a PVC plastisol 152 is applied via a second station 150 in order to provide a decorative layer. Again with a doctor blade 154, the thickness of this layer of plastisol is set. The plastisol 152 is pregelled at a second drying station 160. After the application of a decorative pattern by means of a printing station 170, a transparent PVC plastisol 182 is then applied via a third station 180 in order to provide a wear layer. Again with a doctor blade 184, the thickness of this layer of plastisol is set. The plastisol 182 is pregelled at a third drying station 190. The printing station can be a digital printer, but can just as well be a rotogravure cylinder for rotary printing. In the case of rotary printing, it is possible that the intermediate product is again turned before and after the printer in order to position the printing roll under the product to be printed.

At a turning station 200, the intermediate product is turned so that the second side of the textile product 130 permeated with plastisol is turned upward. On this side of the textile product 130 permeated with plastisol, a further PVC plastisol layer 212 is then applied at a station 210. Again with a doctor blade 214, the thickness of this PVC plastisol layer is set. This plastisol can optionally be a foamable plastisol.

A further textile product 11 1 is brought into contact with the wet PVC plastisol 212, and by means of a light pressure exerted for example by the roll 220, the PVC plastisol 212 partially impregnates the further textile product 1 11 , for example a glass fiber nonwoven.

At drying station 230, the PVC plastisol 212 is pregelled.

Subsequently, a layer of a foamable PVC plastisol 242 is applied at station 240, wherein again the doctor blade 244 is to determine the thickness of the applied layer. Subsequently, the plastisol 242 is first pregelled in an oven 250, and all of the layers of plastisol are then to be gelled in this oven. During this passage through the oven 250, all of the pregelled plastisols are to be further gelled, and the foamable plastisol or plastisols are to foam. The pregelling of plastisol 242 and gelling of all of the layers of plastisol can also be carried out in one step and in one oven.

Finally, the product obtained is turned at turning station 260, after which a UV-hardened PU lacquer layer is applied by means of a lick roller 270 and is hardened with UV at station 280.

The floor covering 300 thus obtained can be rolled up at rolling-up station 290.

The product obtained 300 has a cross section as schematically shown in Fig. 2. As the representation is schematic, the thicknesses as shown are not metrically representative.

The PVC-based, layered floor covering comprises successive layers, specifically:

a. a first PVC layer 1240 that is obtained at station 240;

Textile product 11 1 is a glass fiber nonwoven with a surface weight of 50 g/m ² and a thickness of approximately 0.4 mm.

PU lacquer is applied in an amount of 20 g/m ² and a thickness of 20 pm. A 100% solid UV lacquer is used.

The ALw is 20 dB: this value represents the improvement in contact sound insulation by means of using the product.

The product, like all products in accordance with the invention, has particularly favorable values in terms of expansion under the influence of temperature. The above-mentioned product was subjected to a dilation test in accordance with EN ISO 23999. A product identical to the above-mentioned product but with a glass fiber reinforcement was subjected to the test in a similar manner. For both the production direction and the direction perpendicular to the production direction, it was found that by using two glass fiber reinforcements, a reduction in expansion by 50% was obtained. It is clear that, although the embodiments and/or the materials for providing embodiments in accordance with the present invention are discussed, various amendments or modifications can be applied without deviating from the scope of this operating range and/or the spirit of this invention. The present invention is by no means limited to the embodiments described above, but can be realized in accordance with different variants without departing from the scope of the present invention.
