  • the present invention relates to a process of active fire extinguishing by intumescent products, that is to say a method to help quell a fire once it has occurred.
  • Firefighting methods are divided into two large groups: active methods and passive methods.
  • Active methods are characterized in that if the fire is in an initial stage or has characteristics that allow act in the vicinity of the flames can directly attack on incen ⁇ given to suppress the flame, in these methods it moves violently air near the fuel or the fuel cools.
  • Intumescent products have been used as passive methods to protect combustible or heat-affected materials from fire.

  • an inert gas forming agent such as melanin which will produce nitrogen and ammonia and expand the film
  • adhesive agents such as acrylic, epoxy, aminic resins, silicones.
  • water can generally be used, to which retardants are added, that is, additives that, mixed with water, improve the intrinsic properties of extinguishing water such as the ammonium salts of the sulfate group, phosphates or polyphosphates.
  • Foams can also be used.
  • the action of the foaming agents lasts until the water evaporates, at the moment when the water evaporates, the foams stop being active. This limitation is not presented by intumescent products.

  • An intumescent product is understood as one that expands by the action of heat, that is, increases its volume by at least 20 times its volume.
  • An example of an intumescent product is constituted by at least four synergistic ingredients:
  • a catalyst agent such as ammonium polyphosphate, which at temperatures of about 200 0 C release polyphosphoric acid, • charforming as organic substances that react with polyphosphoric acid, such as pentaerythritol or dipentaeritrol,

  • the graphite structure is formed by sheets of carbon rings arranged in parallel, between parallel sheets there is enough distance for the introduction of atoms or small molecules. If gas-generating compounds such as sulfur, nitrogen or melamine are introduced, graphite expands with heat. Depending on the nature of the material, the expansion can begin at temperatures below 150 0 C.

  • Ceramifying materials are capable of forming a compact or semi-porous structure, which can replace a polymer present in the intuitive product to the extent that it disappears by combustion.
  • the decomposition gases of the polymer are used to form a slight intumescence, which facilitates the control of fire.
  • nanomaterials help to maintain the thermal insulation of the intumescence at temperatures above 1000 0 C; This prevents the formation of cracks, which would damage the insulating effect.
  • nanomaterials that can be used are silica nano-clays and nanoparticles.
  • active extinction refers to the present invention denotes that it is attacked directly on the fire to quench the flame, in these methods intumescence is formed by violently displacing the air next to the fuel or the fuel cools.
