Furanic grouts

Abstract

Broadly, the invention provides for newly available essentially formaldehyde-free furanic materials for lower-staining, higher reactivity, chemically resistant grout formulations.

1 . A furanic grout comprising:
 a. furfuryl alcohol,   b. between about 1 wt-% and 90 wt-% of said furfuryl alcohol being replaced with 5-hydroxymethyl furan (HMF);   c. an aromatic polyol between about 1 wt-% and 50 wt %;   d. and optionally glycerol, optionally, silane, and optionally water   
     
     
         2 . The furanic grout according to  claim 1 , comprising:
 e. a filler.   
     
     
         3 . The furanic grout according to  claim 2 , wherein the filler comprises an inorganic filler selected from the group consisting of sand, clay, graphite, silicate, silica, carbon fiber, and glass fiber. 
     
     
         4 . The furanic grout according to  claim 1  comprising
 a catalyst.   
     
     
         5 . The furanic grout according to  claim 4 , wherein the catalyst is an acid. 
     
     
         6 . The furanic grout according to  claim 1 , comprising a glycerol and/or silane. 
     
     
         7 . The furanic grout according to  claim 1 , comprising bisphenol-A and/or bisphenol A tar. 
     
     
         8 . A furanic grout comprising:
 a. furfuryl alcohol,   b. between about 1 wt-% and 90 wt-% of said furfuryl alcohol being replaced with 2,5 furan dimethanol (FDM);   c. an aromatic polyol between about 1 wt-% and 50 wt %;   d. and optionally glycerol, optionally, silane, and optionally water   
     
     
         9 . The furanic grout according to  claim 8  comprising:
 e. a filler.   
     
     
         10 . The furanic grout according to  claim 9 , wherein the filler comprises an inorganic filler selected from the group consisting of sand, clay, graphite, silicate, silica, carbon fiber, and glass fiber. 
     
     
         11 . The furanic grout according to  claim 8 , comprising
 a catalyst.   
     
     
         12 . The furanic grout according to  claim 11 , wherein the catalyst is an acid. 
     
     
         13 . The furanic grout according to  claim 8 , comprising a glycerol and/or silane. 
     
     
         14 . The furanic grout according to  claim 8 , comprising bisphenol-A and/or bisphenol A tar. 
     
     
         15 . A furanic grout comprising:
 a. furfuryl alcohol,   b. between about 1 wt-% and 90 wt-% of said furfuryl alcohol being replaced with blends of HMF and FDM at weight ratios between the two components of about 1 to about 99 HMF to FDM, to about 99 to about 1 HMF to FDM;   c. an aromatic polyol between about 15 wt-% and 50 wt %;   d. and optionally glycerol, optionally, silane, and optionally water   
     
     
         16 . The furanic grout according to  claim 15  comprising:
 e. a filler.   
     
     
         17 . The furanic grout according to  claim 16 , wherein the filler comprises an inorganic filler selected from the group consisting of sand, clay, graphite, silicate, silica, carbon fiber, and glass fiber. 
     
     
         18 . The furanic grout according to  claim 15 , comprising
 a catalyst.   
     
     
         19 . The furanic grout according to  claim 18 , wherein the catalyst is an acid. 
     
     
         20 . The furanic grout according to  claim 15 , comprising a glycerol and/or silane. 
     
     
         21 . The furanic grout according to  claim 15 , comprising bisphenol-A and/or bisphenol A tar.
