Abstract
A fire retardant composition and process for treating water absorbent material such as natural and synthetic fibers used in fabrics or paper or cardboard-like materials, which utilizes dibasic ammonium phosphate, dibasic ammonium sulfate, and ammonium biborate, mixed with water, that is applied to the fabric, allowed to soak in, and then dry to create the fire retardant characteristics. The composition and process is especially useful for items such as a terrycloth blanket, which itself can be used to smother fires as a safety device.
Claims5
A process for retarding the flammability of absorbent materials selected from the group consisting of fabrics, fibers, and papers, said process consisting of:
- immersing the fabrics or fibers or papers in a mixture of dibasic ammonium phosphate, dibasic ammonium sulfate, ammonium biborate, a surfactant selected from Triton X, and water, in a dry rate ratio of 20% ammonium phosphate, 45.7% dibasic ammonium sulfate, 34% ammonium biborate, and 0.3% surfactant, all of which is then mixed with water in a ratio of two pounds of said dry mixture to one gallon of water;
- wringing out the mixture from the fabrics or fibers or papers;
- and
- drying the fabrics or fibers or papers below 250.degree. F.
A flame retardant composition suitable for spraying, dipping, or applying to a fibrous material, such as a blanket or other water absorbent material, consisting of:
- an admixture of dibasic ammonium phosphate, dibasic ammonium sulfate, and ammonium biborate, in a dry state ratio of 15%-25% of ammonium phosphate, 40.7%-50.7% of dibasic ammonium sulfate, 29%-39% of ammonium biborate, all of which, when mixed to a 2 lb. dry weight mixture, would be mixed with one gallon of water.
A flame retardant composition suitable for spraying, dipping, or applying to a fibrous material, such as a blanket or other water absorbent material, consisting of:
- an admixture of dibasic ammonium phosphate, dibasic ammonium sulfate, ammonium biborate, and a surfactant selected from Triton X, in a dry state ratio of 15%-25% of ammonium phosphate, 40.7%-50.7% of dibasic ammonium sulfate, 29%-39% of ammonium biborate, a surfactant such as Triton X in the amount of 0.3% dry weight, all of which, when mixed to a 2 lb. dry weight mixture, would be mixed with one gallon of water.
A flame retardant composition suitable for spraying, dipping, or applying to a fibrous material, such as a blanket or other water absorbent materials, consisting of:
- an admixture of dibasic ammonium phosphate, dibasic ammonium sulfate, and ammonium biborate, in a dry rate ratio of 20% ammonium phosphate, 45.7% dibasic ammonium sulfate, and 34.3% ammonium biborate, all of which when mixed to a two pound dry weight mixture would be mixed with one gallon of water.
A flame retardant composition suitable for spraying, dipping, or applying to a fibrous material, such as a blanket or other water absorbent materials, consisting of:
- an admixture of dibasic ammonium phosphate, dibasic ammonium sulfate, and ammonium biborate, in a dry state ratio of 20% ammonium phosphate, 45.7% dibasic ammonium sulfate, and 34.0% ammonium biborate, all of which when mixed to a two pound dry weight mixture would be mixed with one gallon of water;
- and
- a surfactant selected from Triton X in the amount of 0.3% dry weight.
