Abstract

Disclosed herein are floor tiles comprising, for instance, a substrate and a surface coating, wherein the surface coating comprises (i) a base formula comprising a glaze and (ii) particles comprising alumina trihydrate.

Claims (26)

1. A floor tile comprising:

a substrate; and

a surface coating provided on an upper surface of the substrate, the surface coating comprising:

a base formula; and

particles,

wherein the base formula comprises a glaze,

wherein the particles comprise alumina trihydrate,

wherein the base formula and the particles remain separate after firing,

wherein the floor tile is a ceramic floor tile, and

wherein the particles make up from 1% to 7% of the weight of the surface coating after firing.

2. The floor tile of claim 1 , wherein the surface coating further comprises particles comprising tabular alumina.

3. The floor tile of claim 1 , wherein the surface coating further comprises particles comprising alumina-zirconium-silicate.

4. The floor tile of claim 3 , wherein the weight of particles comprising alumina-zirconium-silicate and the weight of particles comprising alumina trihydrate is substantially equal.

5. The floor tile of claim 1 , wherein the surface coating further comprises particles comprising alumina-zirconium-silicate and particles comprising tabular alumina.

6. The floor tile of claim 5 , wherein the weight ratio of particles comprising alumina-zirconium-silicate to particles comprising alumina trihydrate to particles comprising tabular alumina is from 3:3:1 to 5:5:1.

7. The floor tile of claim 5 , wherein the weight ratio of particles comprising alumina-zirconium-silicate to particles comprising alumina trihydrate to particles comprising tabular alumina is approximately 4:4:1.

8. The floor tile of claim 1 , wherein substantially all of the particles have a diameter of less than 33.011 microns.

9. The floor tile of claim 1 , wherein about 90% of the particles have a diameter of less than 20.0436 microns.

10. The floor tile of claim 1 , wherein about 50% of the particles have a diameter of less than 7.25089 microns.

11. The floor tile of claim 1 , further comprising a base coating disposed substantially between the substrate and the surface coating.

12. The floor tile of claim 11 , wherein the base coating supports the surface coating during a firing process, wherein at least a portion of the firing process occurs at above 1150 degrees Celsius.

13. The floor tile of claim 1 , wherein the surface coating provides a clean-ability ΔE of 0.6 to 1.0 and a dynamic coefficient of friction of 0.60 to 0.95.

14. The floor tile of claim 1 , wherein the glaze comprises a frit, a clay, and an opacifier.

15. The floor tile of claim 1 , wherein an average RMS of the floor tile is from 11.5 microns to 12.6 microns.

16. The floor tile of claim 1 , wherein an average Ra of the floor tile is from 9.5 microns to 11.0 microns.

17. The floor tile of claim 1 , wherein an average RMS of the floor tile is from 11.5 microns and 12.6 microns and an average Ra of the floor tile is from 9.5 microns and 11.0 microns.
