Abstract

There is provided a gas generating composition having good combustion performance. The gas generating composition comprises a fuel, an oxidizing agent and a binder, wherein the binder is at least one selected from polylactone compounds. Poly-ε-caprolactone is preferable as the polylactone compound, and the weight average molecular weight thereof is preferably in the range of 100 to 100,000.

Claims

1. A gas generating composition comprising a fuel, an oxidizing agent and at least one binder selected from the group consisting of polylactone compounds, concentrations of ammonia and nitrogen dioxide being substantially 0 ppm in analysis results of a discharged gas after combustion of the composition.

2. The gas generating composition as claimed in claim 1, wherein the weight average molecular weight of the polylactone compound is 100 to 100,000.

3. The gas generating composition as claimed in claim 1, wherein the fuel is a nitrogen-containing organic compound, the oxidizing agent is an inorganic oxidizing agent, and the gas generating composition further comprises additives as necessary.

4. The gas generating composition as claimed in claim 2, wherein the fuel is a nitrogen-containing organic compound, the oxidizing agent is an inorganic oxidizing agent, and the gas generating composition further comprises additives as necessary.

5. The gas generating composition as claimed in claim 1, wherein the nitrogen-containing organic compound is at least one selected from the group consisting of guanidine nitrate, nitroguanidine, 5-aminotetrazole, dicyandiamide, azodicarbonamide, ammonium nitrate, melamine and glycine.

6. The gas generating composition as claimed in claim 2, wherein the nitrogen-containing organic compound is at least one selected from the group consisting of guanidine nitrate, nitroguanidine, 5-aminotetrazole, dicyandiamide, azodicarbonamide, ammonium nitrate, melamine and glycine.

7. The gas generating composition as claimed in claim 1, wherein the inorganic oxidizing agent is at least one selected from the group consisting of basic copper nitrate, sodium nitrate, potassium nitrate, strontium nitrate, sodium perchlorate, potassium perchlorate and strontium perchlorate.

8. The gas generating composition as claimed in claim 2, wherein the inorganic oxidizing agent is at least one selected from the group consisting of basic copper nitrate, sodium nitrate, potassium nitrate, strontium nitrate, sodium perchlorate, potassium perchlorate and strontium perchlorate.
