Abstract

A floor element for forming a floor covering, wherein the floor element comprises a decorative layer made of a ceramic material and a support layer arranged below this decorative layer, wherein the support layer comprises edges provided with coupling elements configured to allow a mechanical coupling with coupling elements of an adjacent floor element and wherein the floor element comprises an intermediate layer having a resin material that permeates a lower surface of the decorative layer.

Claims (36)

1. A floor element for forming a floor covering, wherein the floor element comprises:

a decorative layer made of a ceramic material; and

a support layer arranged below the decorative layer,

wherein the support layer comprises edges provided with coupling elements configured to allow a mechanical coupling with coupling elements of an adjacent floor element, and

wherein the floor element comprises an intermediate layer comprising a resin material having a viscosity below 1000 Pas at 20° C. that permeates a lower surface of the decorative layer.

2. The floor element according to claim 1 , wherein the resin material comprises epoxy.

3. The floor element according to claim 1 , wherein the resin material has a viscosity below 800 Pas at 20° C.

4. The floor element according to claim 1 , wherein the intermediate layer covers 80 percent or more of the lower surface of the decorative layer.

5. The floor element according to claim 1 , wherein the intermediate layer comprises a resin content of at least 150 g/sqm.

6. The floor element according to claim 1 , wherein the intermediate layer is an adhesive layer that bonds together the decorative layer and the support layer.

7. The floor element according to claim 1 , wherein the decorative layer has an apparent porosity comprised between 0.1% and 10% measured according to ASTM C373.

8. The floor element according to claim 1 , wherein the decorative layer has a volume of open pores comprised between 0.01 cc and 1 cc measured according to ASTM C373.

9. The floor element according to claim 1 , wherein the decorative layer comprises a red body ceramic tile.

10. The floor element according to claim 1 , wherein the decorative layer comprises a glazed upper surface.

11. The floor element according to claim 1 , wherein the support layer comprises rigid polyvinylchloride (PVC).

12. The floor element according to claim 1 , wherein the support layer has a flexural modulus between 1.5 and 3.5 GPa.

13. The floor element according to claim 1 , wherein the support layer has a thickness of 6 mm or less.

14. A floor covering comprising a plurality of floor elements according to claim 1 .

15. A method for manufacturing a floor element, comprising the steps of:

providing a decorative layer made of a ceramic material;

providing a support layer;

providing a resin material for bonding the decorative layer and the support layer together; and

pressing the layers together for forming the floor element such that the resin material permeates the ceramic layer,

wherein the resin material has a viscosity below 1000 Pas at 20° C.

16. The method of claim 15 , wherein the pressing step comprises a pressing time of at least 1 second.

17. The method of claim 15 , wherein during the pressing step a pressure of at least 350 kg/sqm is exerted onto the layers.

18. A resin material for bonding together a decorative layer made of a ceramic material and a support layer to form a floor element according to claim 1 , wherein the resin material comprises epoxy having a viscosity below 1000 Pas at 20° C.

19. A floor element comprising:

a decorative layer made of a ceramic material; and

a support layer arranged below the decorative layer,

wherein the support layer comprises at least two couples of opposite edges,

wherein the opposite edges comprise coupling elements configured to allow a mechanical coupling with coupling elements of adjacent floor elements,

wherein the first coupling elements at the first couple of opposite edges are configured for being coupled to the coupling elements of adjacent floor elements by means of an angling motion around a horizontal axis parallel to the respective edges,

wherein the second coupling elements at the second couple of opposite edges are configured for being coupled to the coupling elements of adjacent floor elements by means of a translational downward direction of the respective edges towards each other, and

wherein the floor element further comprises an intermediate layer comprising a resin material having a viscosity below 1000 Pas at 20° C. that permeates a lower surface of the decorative layer.

20. The floor element according to claim 19 , wherein in the coupled condition, said first coupling elements are coupled with play.
