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 realize a mechanical coupling with coupling elements of an adjacent floor element and wherein the floor element comprises an intermediate layer having a resin material and wherein said resin material comprises a modulus of elasticity greater than 0.1 GPa, preferably greater than 0.5 GPa, even more preferably greater than 1 GPa.

Claims (31)

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

a decorative layer made of a ceramic material;

a support layer arranged below the decorative layer; and

an intermediate layer,

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

wherein the intermediate layer comprises a resin material that permeates a lower surface of the decorative layer,

wherein the resin material comprises a modulus of elasticity greater than 0.1 GPa wherein the impact resistance of the floor element is greater than 5 J.

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 less than 1000 mPas at 20° C.

4. The floor element according to claim 1 , wherein the resin material comprises an elongation at break less than 200%.

5. The floor element according to claim 1 , wherein the resin material has an elongation at break greater than 1%.

6. The floor element according to claim 1 , wherein the resin material comprises a tensile strength between 20 and 90 MPa.

7. The floor element according to claim 1 , wherein the resin comprises a compressive strength between 90 and 130 MPa.

8. The floor element according to claim 1 , wherein the resin comprises a hardness value of at least 50 measured on a Shore D scale.

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

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

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

12. The floor element according to claim 1 , wherein the decorative layer has a back-face structure comprising excavation with a depth less than 0.6 mm.

13. The floor element according to claim 1 , wherein the support layer comprises rigid PVC.

14. The floor element according to claim 1 , wherein the support layer has a flexural modulus between 5 and 10 GPa.

15. The floor element according to claim 1 , wherein the support layer has a thickness less than 6 mm.

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

17. A floor element for forming a floor covering, the floor element comprising:

a decorative layer made of a ceramic material;

an intermediate layer; and

a support layer arranged below the decorative layer,

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

wherein the intermediate layer comprises a resin material that permeates a lower surface of the decorative layer, and

wherein the support layer is made of a material that comprises a flexural modulus above 5 GPa and/or a flexural strength between 20 and 90 MPa wherein the impact resistance of the floor element is greater than 5 J.

18. The floor element according to claim 17 , wherein the support layer is made of a thermoplastic material.

19. The floor element according to claim 17 , wherein the support layer comprises between 50 and 75% weight of filler.
