US 2003/0170317 A1 · Flame retardant and microbe inhibiting methods and compositions

Abstract

The present invention provides combined property, dual-action compositions for application to a material, such as Gypsum Wall Board, ceiling tiles, joint compounds, concrete and other interior building materials, prior to an exposure of the material to fire, or prior to, during or after exposure of the material to conditions favorable to the growth of microbes. When compositions within the present invention are properly applied to a material prior to the material being exposed to fire, or prior to, during or after the material being exposed to conditions favorable to the growth of microbes, these compositions have the effect of reducing the amount of burning that occurs to the material, and/or reducing the amount or density of smoke and associated toxic gases produced by the material, when the material is exposed to fire. These compositions also have the effect of inhibiting or reducing the growth, build-up or deposit of microbes on the material when the material is exposed to conditions favorable to the growth of microbes. The present invention also provides methods for reducing the burning of, and/or the amount or density of smoke and associated toxic gases produced by, a material that is exposed to fire, and for inhibiting or reducing the growth, build-up or deposit of microbes on a material that is exposed to conditions favorable to the growth of microbes, comprising applying a composition of the present invention to the material at least one time prior to the material being exposed to the fire, or prior to, during or after the material being exposed to conditions favorable to the growth of microbes, at a rate of about 1 gallon per from about 100 to about 1,000 square feet of the material.

Dependent claims

A composition for application to a material comprising:

(a) at least one alkaline metal inorganic salt, wherein the alkaline metal inorganic salt is present in the composition in an amount ranging from about 5% to about 45% by weight;
(b) at least one potassium salt of an organic acid, wherein the potassium salt of an organic acid is present in the composition in an amount ranging from about 5% to about 50% by weight;
(c) optionally, at least one boron-containing compound, wherein the boron-containing compound is present in the composition in an amount ranging from about 0% to about 10% by weight;
(d) optionally, at least one surfactant, wherein the surfactant is present in the composition in an amount ranging from about 0% to about 5% by weight;
(e) optionally, at least one microbe-inhibiting compound, wherein the microbe-inhibiting compound is present in the composition in an amount ranging from about 0% to about 6% by weight;
(f) optionally, at least one detection component, wherein the detection component is present in the composition in an amount ranging from about 0% to about 10% by weight;
and
(g) an aqueous liquid, wherein the aqueous liquid is present in the composition in an amount that brings the percent weight of the composition to 100%;
wherein the composition has a pH ranging from about 7.1 to about 14, and wherein the composition, when applied to the material, reduces the amount of burning that occurs to the material, or the amount or density of smoke produced by the material, when the material is subsequently exposed to fire, and when the composition is applied to a material prior to, during or after the material being exposed to conditions favorable to the growth of microbes, reduces or inhibits the growth of microbes on the material when the material is exposed to conditions favorable to the growth of microbes.
