FIELD: fire extinguishing agents.
SUBSTANCE: invention relates to autonomous fire extinguishing means that do not require the use of automation and human participation. The composite material contains the following components, wt%: polymer matrix - colloxylin nitrocellulose with a nitrogen content of 10.7-12.2% - 20-50; microcapsules with an extinguishing agent core - 50-80; stabilizer - 1-2; plasticizer - 0-25. The composite material contains liquid or gaseous halogenated hydrocarbons as the core of the extinguishing agent, for example, 2-dibromohexafluoropropane, 1,4-dibromoctafluorobutane, 1,1,2,3,3,3-heptafluoropropane, octofluorocyclobutane. The composite material contains diphenylmethane, centralites as a stabilizer, and dibutyl phthalate as a plasticizer.
EFFECT: invention makes it possible to increase efficiency of fire extinguishing of ignition centers in volumes of the facilities to be protected, at earlier stages, and to preserve the performance of the product in conditions of high humidity and to reduce smoke generation.
