Systems and methods for cleanable and slip resistant tile
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.
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.
