Abstract
A fire retardant material includes a deconstructed nanoporous material including a plurality of elements, and solids of a fire-retarding solution within the elements of the nanoporous material. A method of forming the fire retardant material includes combining a nanoporous material and a fire-retarding solution such that elements of the nanoporous material absorb the fire retarding solution, and evaporating liquid from the elements of the nanoporous material having the fire-retarding solution absorbed therein such that a concentrate or solids thereof remain within the elements of the nanoporous material.
Claims6
A method of forming a fire retardant material, comprising:
- treating a plurality of elements of a nanoporous material, said treating including heating the nanoporous material, without sintering the nanoporous material, to render any hydrophobic elements of the nanoporous material unsintered and hydrophilic;
- combining the elements of the unsintered and hydrophilic nanoporous material, the nanoporous material comprising a silica-based nanoporous material or a silicate-based nanoporous material, and an aqueous fire-retarding solution such that the elements of the unsintered and hydrophilic nanoporous material absorb the aqueous fire retarding solution;
- and
- evaporating water from the elements of the nanoporous material having the aqueous fire-retarding solution absorbed therein such that a concentrate or solids thereof remain within the elements of the nanoporous material,
- wherein combining the elements of the nanoporous material and the aqueous fire-retarding solution comprises combining the elements of the nanoporous material and the aqueous fire-retarding solution comprising a boron compound, a phosphorus compound, a lithium compound, a fluorine compound, an antimony compound, a borate compound, boric acid, an inorganic hydrate, a bromine compound, an aluminum compound, magnesium hydroxide, a phosphonium salt, a zirconium salt, ammonium phosphate, diammonium phosphate, methyl bromide, methyl iodide, bromochlorodifluoromethane, dibromotetrafluoroethane, dibromodifluoromethane, urea, guanidine, or combinations thereof.
