Non-vinyl flooring and method for making same

Abstract

In one embodiment or the present invention, a non-vinyl flooring is described comprising a flooring substrate having a non-vinyl composition comprising a terpolymer comprising ethylene, methyl acrylate and acrylic acid and a copolymer comprising ethylene and methacrylic acid. In one embodiment of the present invention, the non-vinyl flooring comprises a resilient non-vinyl floor tile comprising a non-vinyl composition comprising a terpolymer and a copolymer. In another embodiment of the present invention, the non-vinyl flooring comprises a resilient non-vinyl sheet flooring comprising a non-vinyl composition comprising a terpolymer and a copolymer. Methods for making the non-vinyl tile and non-vinyl sheet flooring are described.

1 . (canceled) 
   
   
       2 . A composition comprising:
 a flooring substrate having a non-vinyl composition comprising a terpolymer comprising ethylene, methyl acrylate and acrylic acid and a copolymer to raise the modulus of the overall composition.   
   
   
       3 . The composition of  claim 2 , further comprising a pigment. 
   
   
       4 . The composition of  claim 2 , further comprising a mottle. 
   
   
       5 . The composition of  claim 4 , wherein the mottle comprises a pigment. 
   
   
       6 . The composition of  claim 4 , wherein the mottle comprises flakes having the same chemical components as the flooring substrate. 
   
   
       7 . The composition of  claim 4 , wherein the mottle comprises trim. 
   
   
       8 . The composition of  claim 2 , further comprising a mottle on a top surface of the flooring substrate. 
   
   
       9 . The composition of  claim 2 , wherein the terpolymer comprises approximately 8 to 30% by weight of the flooring substrate. 
   
   
       10 . The composition of  claim 2 , wherein the copolymer comprises approximately 0.1 to 16% by weight of the flooring substrate. 
   
   
       11 . The composition of  claim 2 , further comprising a protective layer on a top surface of the flooring substrate. 
   
   
       12 . The composition of  claim 2 , wherein the protective layer comprises urethane. 
   
   
       13 . The composition of  claim 2 , wherein the flooring substrate comprises a sheet flooring. 
   
   
       14 . The composition of  claim 13 , wherein the flooring substrate further comprises a backing substrate attached to the non-vinyl composition. 
   
   
       15 . The composition of  claim 2 , wherein the flooring substrate comprises a floor tile. 
   
   
       16 . The composition of  claim 15 , further comprising: a first mottle; and a second mottle below the first mottle on a top surface of the floor tile. 
   
   
       17 . The composition of  claim 2 , further comprising limestone. 
   
   
       18 . The composition of  claim 17 , wherein the terpolymer comprises approximately 8-30% by weight of the composition, the copolymer comprises approximately 0.1-16% by weight of the tile composition, and the limestone comprises over 50% by weight of the composition.
