Abstract

The present invention pertains to the field of fire-extinguishing systems and relates to an ozone-friendly fire-extinguishing material on the basis of a polymeric composition. This material comprises a cold-solidification polymeric binder as well as a micro-encapsulated fire-extinguishing agent, wherein said agent consists of substances selected from the group of organic halogen compounds of the formulae C3F7I or CnF2n+2 or (C2F5)2N(CmF2m+1) in which n = 5 - 7 and m = 1 - 2. The components of this composition are selected in the following amounts: from 40 to 60 wt.% of micro-encapsulated fire-extinguishing agent, the balance consisting of the polymeric binder. The cold-solidification polymeric binder is selected from the group of polyepoxides containing diane or aliphatic epoxide resins (including those containing chlorine) or a mixture of diane and aliphatic epoxide resins or from the group of polyurethanes. The material consists of a heat-reactive polymeric composition containing a dispersion filler in the form of a micro-encapsulated fire-extinguishing agent. The fire-extinguishing agent is made in the shape of microcapsules each consisting of microspheres having a diameter of between 100 and 400 νm, wherein said microspheres are made of a polymeric envelope that contains a liquid fire-extinguishing agent. According to the casting form used, the material can be produced in the shape of liner sheets, in the shape of formed articles having a given configuration or in the shape of a cold-solidification putty.

Area of technology

The proposed invention is supplied with the equipment for the suppression of fire and is intended for the use of a thermo-interactive equipment that is in good condition. The product provides automatic pressure suppression of the firing load and can be used effectively in aviation to protect the most vulnerable to nodes; in energy for local automatic protection, the most vulnerable nodes and aggregates of power installations (including nuclear ones); in the case of electric shock to protect against accidental electric shock and electric shock, and also to protect against electrical shock

The level of technology The known use of viscous and flame-retardant materials (1, 2, 3) for the prevention of the spread of flame is generally The components of this class of fire and the thermal impact of the fire create a non-combustible fire barrier on the paths of the fire suppression. Failure of the indicated materials is the absence of the active pressure of the burner and, as a result, the temporary nature of the protective action. The known use of liquids, gas and aerosol extinguishing agents used in an automatic fire extinguishing system (4, 5, 6, 10, 1, 1, 2, 1, 10, 1, 2).
