Abstract

The present disclosure describes various building materials used in the building and construction industry, and to buildings or objects constructed therefrom, and to methods of making these building materials. The building materials comprise a polymeric material, such as sodium alginate and/or calcium alginate which confers significant flame-, fire- and heat-resistance or imperviousness to the materials. Other substances can be added to the materials to improve cross-linking and/or to produce resistance to fungal degradation. The building materials which can be produced, processed, or treated using the alginate polymers of the invention include, but are not limited to, wood products; masonry products; wall, roofing, flooring and siding products; and paint products. Further, sodium alginate in the form of a gel may be used as a firebreak to effectively stop the advance of grass fires, wildfires, and forest fires.

Claims

exact text as granted — not AI-modified
1 . A building material product for use in construction, comprising:
 a construction material matrix component; and   an alginate polymer component dispersed on or within the construction material matrix component.   
     
     
         2 . The building material product of  claim 1  wherein the alginate polymer component comprises sodium alginate and/or calcium alginate. 
     
     
         3 . The building material product of  claim 1  wherein the alginate polymer component further comprises a cross-linking agent. 
     
     
         4 . The building material product of  claim 3  wherein the cross-linking agent is at least one of a xanthan gum, a carrageenan, and an agar. 
     
     
         5 . The building material product of  claim 1  wherein the alginate polymer component further comprises an anti-mold or anti-fungal agent. 
     
     
         6 . The building material product of  claim 1  wherein the alginate polymer component comprises 1% to 25% by weight of the building material product. 
     
     
         7 . The building material product of  claim 1  comprising a wood product. 
     
     
         8 . The building material product of  claim 1  comprising a masonry product. 
     
     
         9 . The building material product of  claim 1  comprising a paint product. 
     
     
         10 . The building material product of  claim 1  comprising a siding product. 
     
     
         11 . The building material product of  claim 1  comprising a flooring product. 
     
     
         12 . The building material product of  claim 1  comprising a roofing product. 
     
     
         13 . A building or building component comprising a building material product of  claim 1 . 
     
     
         14 . A fence or fence component comprising a building material product of  claim 1 . 
     
     
         15 . A method of producing a building material product, comprising:
 providing a construction material matrix component;   providing an alginate polymer component;   combining the construction material matrix component and the alginate polymer component; and   processing the combined construction material matrix component and alginate polymer component to form the building material product.   
     
     
         16 . The method of  claim 15  wherein the alginate polymer component comprises sodium alginate and/or calcium alginate. 
     
     
         17 . The method of  claim 15  wherein the alginate polymer component further comprises a cross-linking agent. 
     
     
         18 . The method of  claim 17  wherein the cross-linking agent is at least one of a xanthan gum, a carrageenan, and an agar. 
     
     
         19 . The method of  claim 15  wherein the alginate polymer component further comprises an anti-mold or anti-fungal agent. 
     
     
         20 . The method of  claim 15  wherein the alginate polymer component comprises 1% to 25% by weight of the building material product. 
     
     
         21 . The method of  claim 15  wherein the building material product comprises at least one of a wood product, a masonry product, a paint product, a siding product, a flooring product, and a roofing product.
