Abstract
An autonomous fire-fighting agent (10) formed from a material with fire-extinguishing properties. The material includes: microcapsules with a fire-extinguishing composition, the microcapsules having sizes of from 2 to 100 μm and being in the form of a halocarbon enclosed in a polymeric shell consisting of polyurea and/or polyurethane; and a binder. The binder includes a composite material having a polymeric component and mineral fibers and/or particles. The invention also relates to a method for manufacturing an autonomous fire-fighting agent (10) and an object which uses the autonomous fire-fighting agent (10) to fight a fire 10-20 s after ignition.
Claims16
An autonomous firefighting agent for fire extinguishing, the autonomous firefighting agent comprising:
- a composite material, said composite material having fire extinguishing properties, the composite material comprising microcapsules, the microcapsules having a size from 2 to 95 μm and containing a halocarbon fire extinguishing agent surrounded by a polymer shell composed of polyurea and/or polyurethane based on a polyisocyanate prepolymer, said microcapsules being dispersed in a binding composition comprising a polymer component as a polymer base and mineral fillers in a form of mineral fibers and/or particles, wherein the composite material is in the shape of a plate, said composite material comprising a glue layer applied onto one side of said plate and coated with a detachable protective film.
An autonomous firefighting agent for fire extinguishing, the autonomous firefighting agent comprising:
- a composite material, said composite material having fire extinguishing properties, said composite material comprising microcapsules, said microcapsules having a size from 2 to 95 μm, said microcapsules comprising a halocarbon fire extinguishing agent and a polymer shell composed of polyurea and/or polyurethane based on a polyisocyanate prepolymer, said polymer shell surrounding said halocarbon fire extinguishing agent, said microcapsules being dispersed in a binding composition comprising a polymer component as a polymer base and mineral fillers in a form of mineral fibers and/or particles, wherein said composite material is plate-shaped, said composite material comprising a glue layer applied onto one side of said plate and coated with a detachable protective film, the composite material being configured to extinguish a fire upon the composite material reaching a predetermined temperature.
An object, comprising:
- an autonomous firefighting agent for putting out fire, said autonomous firefighting agent comprising a composite material, said composite material comprising microcapsules with a size from 2 to 95 μm, said microcapsules containing a halocarbon fire extinguishing agent surrounded by a polymer shell composed of polyurea and/or polyurethane based on a polyisocyanate prepolymer, said microcapsules being dispersed in a binding composition comprising a polymer component as a polymer base and mineral fillers in a form of mineral fibers and/or particles, wherein the composite material is plate shaped, said composite material comprising a glue layer applied onto one side of said plate and coated with a detachable protective film.
