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 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, wherein the floor element comprises an intermediate layer having a resin material that permeates a lower surface of the decorative layer, and wherein the intermediate layer is an adhesive layer that bonds together the decorative layer and the support layer.

Claims (33)

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

a decorative layer made of a brittle material, the brittle material comprising a sintered ceramic material;

a support layer arranged below the decorative layer; and

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

wherein the intermediate layer is an adhesive layer that bonds the decorative layer and the support layer together.

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

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

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

5. The floor element according to claim 1 , wherein the resin material has a viscosity less than 1000 Pas at 20° C.

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

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

8. 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.

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

10. The floor element according to claim 9 , wherein the support layer comprises more than 30 wt % of fillers.

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

12. The floor element according to claim 1 , wherein the support layer is less than 6 mm thick.

13. The floor element according to claim 1 , wherein the floor element comprises a superficial area of less than 1.5 sqm.

14. The floor element according to claim 1 , wherein the weight of the floor element is at least 18 kg/sqm.

15. The floor element according to claim 1 , wherein the coupling elements are configured in such a way that in a coupled condition a play is established between coupled coupling elements.

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

17. A method for manufacturing a floor element, the method comprising:

providing a decorative layer made of a brittle material;

providing a support layer;

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

pressing the decorative layer and the support layer together for forming the floor element such that the resin material permeates the decorative layer.

18. The method of claim 17 , wherein the pressure is maintained for a pressing time of at least 1 second.

19. The method of claim 17 , wherein a pressure of at least 350 kg/sqm is applied to the decorative layer and the support layer during the pressing step.

20. The floor element according to claim 1 , wherein the resin comprises at least one of the following properties:

a tensile strength between 50 and 90 MPa,

a compressive strength between 90 and 130 MPa,

and a hardness value of at least 50 measured on a Shore D scale.
