Aesthetically pleasing linoleum based surface coverings

Abstract

Described herein are surface coverings comprising a carrier, a first linoleum composition, and a second linoleum composition; wherein the flow rate of the first linoleum composition is greater than the flow rate of the second linoleum composition.

1 . A surface covering comprising:

 linoleum cement; 
 a first organic filler; and 
 a first inorganic filler; and 
   a second linoleum composition having a second flow rate (V max ) that is less than 200 cmm/s, the second linoleum composition adjacent to the first linoleum composition and comprising:
 linoleum cement; 
 a second organic filler; and 
 a second inorganic filler; and 
   wherein the ratio of the first linoleum composition flow rate (V max ) to the second linoleum composition flow rate (V max ) ranges from about 5:1 to about 20:1.   
     
     
         2 . The surface covering of  claim 1 , wherein the V max  of the first linoleum composition is about 600 cmm/s to about 800 cmm/s. 
     
     
         3 . The surface covering of  claim 1  or  claim 2 , wherein the V max  of the second linoleum composition is less than about 100 cmm/s. 
     
     
         4 . The surface covering of  claim 1 , wherein the carrier is embedded in the first linoleum composition. 
     
     
         5 . The surface covering of  claim 1 , wherein the first linoleum composition further comprises a metal oxide or a metal hydroxide, wherein the metal oxide comprises zinc oxide. 
     
     
         6 . The surface covering of  claim 1 , wherein the first linoleum composition comprises from about 30 wt. % to about 45 wt. % of linoleum cement. 
     
     
         7 . The surface covering of  claim 1 , wherein the first linoleum composition comprises from about 15 wt. % to about 30 wt. % of the first organic filler. 
     
     
         8 . The surface covering of  claim 1 , wherein the first linoleum composition comprises from about 20 wt. % to about 40 wt. % of the first inorganic filler. 
     
     
         9 . The surface covering of  claim 1 , wherein the intersecting grid comprises voids in an amount ranging from about 20 voids/cm2 to about 30 voids/cm2. 
     
     
         10 . The surface covering of  claim 9 , wherein the voids have a length of from about 0.1 mm to about 5 mm, and a width of from about 0.1 mm to about 5 mm. 
     
     
         11 . The surface covering of  claim 9 , wherein the voids have a depth of from about 0.1 mm to about 0.5 mm. 
     
     
         12 . The surface covering of  claim 9 , wherein voids are at least 75% saturated with the first linoleum composition. 
     
     
         13 . A surface covering comprising:
 a carrier comprising an intersecting grid of first strands and second strands comprising from about 20 voids/cm 2  to about 30 voids/cm 2 ;   a first linoleum composition having a first flow rate (V max ), the first linoleum composition adjacent to the carrier and comprising:
 linoleum cement; 
 a first organic filler; and 
 a first inorganic filler in an amount ranging from about 25 wt. % to 35 wt. % based on the total weight of the first linoleum composition; and 
   a second linoleum composition having a second flow rate (V max ) comprising:
 linoleum cement; 
 a second organic filler; 
 a second inorganic filler; and 
   wherein the first inorganic filler comprises particles having an average particle size of from about 0.5 μm to about 20 μm.   
     
     
         14 . The surface covering of  claim 13 , wherein the V max  of the first linoleum composition is about 500 cmm/s to about 900 cmm/s. 
     
     
         15 . The surface covering of  claim 13  or  claim 14 , wherein the V max  of the second linoleum composition is from about 10 cmm/s to about 100 cmm/s. 
     
     
         16 . The surface covering of  claim 13 , wherein the first linoleum composition further comprises a metal oxide or a metal hydroxide, wherein the metal oxide comprises zinc oxide. 
     
     
         17 . The surface covering of  claim 13 , wherein the first linoleum composition comprises from about 30 wt. % to about 45 wt. % linoleum cement. 
     
     
         18 . The surface covering of  claim 13 , wherein the first linoleum composition comprises from about 18 wt. % to about 23 wt. % of the first organic filler. 
     
     
         19 . The surface covering of  claim 13 , wherein voids are at least 90% saturated with the first linoleum composition. 
     
     
         20 . The surface covering of  claim 13 , wherein a ratio of the first flow rate (V max ) of the first linoleum composition to the second flow rate (V max ) of the second linoleum composition, ranges from about 8:1 to about 15:1.
