Abstract
The present invention is directed to pyrotechnic aerosol fire suppression compositions that burn rapidly, but coolly. The rapid burning of the compositions of the present invention produces a voluminous flame-suppressive aerosol that is useful in suppressing and/or extinguishing both small and large fires. The compositions of the invention contain at least one oxidizer and a fuel component comprising at least one organic acid salt, which combination produces a rapid burning composition that burns at low temperatures with little or no flame.
Claims23
A pyrotechnic aerosol fire suppression composition consisting essentially of:
- an oxidizer represented by the formula M(XOx)y, wherein M is selected from a Group IA atom, a Group IIA atom, and a Group IIIA atom, wherein XOx is a bromate;
- a fuel component comprising melamine cyanurate, a Group IA or Group IIA salt of an organic acid, or a mixture thereof, wherein the organic acid is selected from the group consisting of cyanuric acid, isocyanuric acid, hydroxyacetic acid, and mixtures thereof;
- and
- optionally a binder selected from the group consisting of a silicate, a cellulose derivative, a cellulose ether, an alginic binder, a gum, a gel, a pectin, a starch, a polyvinyl compound, and a mixture thereof, and optionally a polyol selected from the group consisting of a glyceroI and a gycol;
- wherein the oxidizer is present in a greater amount by weight percent than the fuel component, and wherein the combustion products consist essentially of H2O, CO2, nitrogen, a halide salt and a carbonate salt.
A pyrotechnic aerosol fire suppressant composition consisting essentially of:
- an oxidizer represented by the formula M(XOx)y, wherein M is selected from a Group IA atom, a Group IIA atom, a Group IIIA atom, X is selected from the group consisting of Br and I, x is 1-4, and y is 1-3, wherein the oxidizer is present in an amount of about 70 percent or less by weight of the composition;
- and
- a fuel component comprising melamine cyanurate, a Group IA or Group IIA salt of an organic acid or a mixture thereof, wherein the fuel component is present in an amount of about 50 percent or less by weight of the composition, wherein the organic acid is selected from the group consisting of cyanuric acid, isocyanuric acid, hydroxyacetic acid, and mixtures thereof,
- wherein the combustion products consist essentially of H2O, CO2, nitrogen, a halide salt, and a carbonate salt.
A pyrotechnic aerosol fire suppressant composition consisting essentially of:
- an oxidizer selected from the group consisting of sodium bromate, potassium bromate, and mixtures thereof;
- a fuel component selected from the group consisting of melamine cyanurate, potassium cyanurate, potassium isocyanurate, potassium hydroxyacetate, magnesium cyanurate, magnesium isocyanurate, magnesium hydroxyacetate, and mixtures thereof, and
- an optional binder present in an amount of about 2 percent to about 20 percent by weight of the composition,
- wherein the weight ratio of the oxidizer to the fuel component is from about 3:2 to about 4:1, and wherein the combustion products consist essentially of H2O, CO2, nitrogen, a halide salt, and a carbonate salt.
