EXTINGUISHANT Russian patent published in 1994 - IPC

FIELD: fire-fighting. SUBSTANCE: mixture of component is prepared to include, mas. % : thermally dispersed component 1.0-35.0; oxidizer 50.0-94.0; combustible binder 3.0-25.0; plasticizer 1.0-20.0; and process additives and modifier of burning 0.1-15.0. Process additives are contained in mixture in amount of 0.01-2.00 mas. % : . Used as oxidizer is potassium or sodium perchlorate or potassium or sodium nitrate, or their mixtures. Used as thermally dispersed component is compound from group containing chloride, sulfate, sulfide and phosphates of alkali and/or alkali-earth metals and their mixtures. Used as combustible binder is substance taken from group containing cellulose ether-ethylcellulose, nitrocellulose with nitrogen content of 12-13% , rubbers-butadiene-nitrile, polyurethane, natural, divinyl styrene or polymer-perchlorovinyl resin, polyvinyl chloride, polyvinyl butyral, polyvinyl acetate or epoxy resin or polyester resin. Used as plasticizer are diester or phosphorous-containing plasticizers, e. g. , dibutyl phthalate, dibutyl sebasinate, glyceryl triacetate, tricresyl phosphate; organic nitrates, e. g. , nitroglycerin, dinitratediethylene glycol, dinitratetriethylene glycol; organic azides of S-triazine series, e. g. , 2.4-diazido-6-amino-S-triazine 2.4-diazido-6-azido-etoxy-8-triazine, 2-azido-4.6-diazidoetoxy-S-triazine or their mixtures. Rubbers, resins and polymers may be introduced with respective hardener. Rubbers and polymers are introduced into compound in form of, respectively, 25-55% latexes or aqueous dispersions in amount of 3-25% by mass. EFFECT: higher efficiency. 6 cl, 1 tbl
