FIELD: fire safety.
SUBSTANCE: invention relates to autonomous fire extinguishing means. A fire extinguishing plate based on microcapsulated extinguishing agents, made in the form of a multilayer structure including functional, bearing, fixing layers, characterized in that the functional layer is a composite material consisting of a polymer matrix and microcapsules with a core of a fire extinguishing agent, while nitrocellulose-colloxylin with a nitrogen content of 10.7% to 12.2% is used as a thermally activated polymer matrix with a nitrogen content of 10.7% to 12.2% with the following ratio of components, weight percentage: thermally activated matrix-nitrocellulose-colloxylin with a nitrogen content from 10.7% to 12.2% - 20-50; microcapsules with a core of a fire extinguishing agent 50-80; in this case, the composite material was obtained using a stabilizer and a plasticizer at the following ratio of components, weight percentage in terms of nitrocellulose: stabilizer 1-2; plasticizer 0-25.
EFFECT: provided is an increase in the fire extinguishing efficiency of the plate.
