Abstract RU 2401253 C1

FIELD: chemistry.

SUBSTANCE: gas-generating fuel contains an oxidising agent and fuel. The oxidising agent is ammonium perchlorate and the fuel is a thermoplastic fuel in form of a chlorine-containing thermoplastic polymer or its mixture with a chlorine-containing low-molecular weight compound in ratio of 1:0.1-1:2, with the following ratio of components, wt %: oxidising agent 60.0-80.0, thermoplastic fuel 20.0-40.0. The chlorine-containing thermoplastic polymer is chlorinated polyethylene or polyvinylchloride or chlorinated polyvinylchloride or chlorosulphonated polyethylene. The chlorine-containing low-molecular weight compound is chlorinated paraffin wax or methyl chloroform, or tetrachloroethane or perchloroethylene or dichlorobenzene or hexachloro-p-xylene. The fuel also contains a process additive - calcium or zinc stearate in amount of 0.05-1.0 wt %.

EFFECT: production of fuel with high energy output, volume of released gases and content of hydrogen chloride.
