Claim:
1. A fire extinguishing composition containing a transition metal salt of an organic acid and a pyrotechnic agent; and the fire extinguishing composition adopts the pyrotechnic agent as a heat source and a power source, reacts and releases a fire extinguishing material through heat emitted by igniting and burning the pyrotechnic agent, the mass percentage of the transition metal salt of the organic acid is 65 wt % to 95 wt %, the fire extinguishing composition further includes an auxiliary fire extinguishing agent in a mass percentage of 5 wt % to 35 wt %, the auxiliary fire extinguishing agent is an amine and/or organic amine salt; wherein the transition metal salt of the organic acid is a ferric salt of an organic acid, a manganese salt of an organic acid, a nickel salt of an organic acid, a copper salt of an organic acid, a zinc salt of an organic acid or a cobalt salt of an organic acid; wherein the ferric salt of the organic acid is one or more of ferric citrate, ferric oleate, ferric linoleate, ferric stearate, ferric benzoate, ferric acetate, ferric salicylate and ferric gluconate; wherein the manganese salt of the organic acid is one or more of manganous acetate, manganous benzoate, manganese salicylate and manganese gluconate; wherein the nickel salt of the organic acid is one or more of nickel oleate, nickel benzoate, and nickel salicylate; wherein the copper salt of the organic acid is one or more of copper formate, copper oleate, copper linoleate, copper stearate, copper tartrate, copper 2-hydroxybutanedioate, copper iso-octoate, copper benzoate, and copper salicylate; wherein the zinc salt of the organic acid is one or more of zinc oleate, zinc citrate, zinc benzoate, zinc methacrylate, zinc salicylate and zinc gluconate; wherein the cobalt salt of the organic acid is one or more of cobalt acetate, cobalt citrate, cobalt iso-octoate, cobalt benzoate, and cobalt salicylate; wherein the organic amine salt includes an organic amine hydrochloride and an organic amine sulphate; wherein the organic amine salt is one or more of 2-methylaniline hydrochloride, 3,3′-dimethylbenzidine dihydrochloride, N′N-dimethyl-p-phenylenediamine sulphate, N,N′-dimethyl-p-phenylenediamine monohydrochloride, N′N-diethyl-p-phenylenediamine sulphate, N,N′-diethyl-p-phenylenediamine monohydrochloride, 1-naphthylamine hydrochloride, aniline hydrochloride, 3-hydroxyphenylamine hydrochloride, diphenylamine hydrochloride, dimethylamine hydrochloride, diethylamine hydrochloride, cyclohexylamine hydrochloride, benzidine sulfate, benzidine phydrochloride, trimethylamine hydrochlorate, ethylenediamine hydrochloride, m-phenylenediamine hydrochloride, o-phenylendiamine hydrochloride, o-bromoaniline hydrochloride, N(1-naphthyl)ethylenediamine hydrochloride and triethanolamine hydrochloride.
