  • PBDEs polybromodiphenyl ether
  • PCBs polychlorobiphenyl
  • Another example of a fire retardant composition is formed by phosphorus compounds that in case of fire react to form polyphosphoric acids and metaphosphoric acids, which constitute an oxygen blocking layer.
  • the fire retardant organ phosphate is also applied as an organophosphate mixture described in US Patent 4 '499, 222, however the effectiveness of such treatment is unstable and is not sufficient to achieve the desired fire retardant capacity. . There is still a demand for more effective action compositions.
  • the invention offers a chemical fire retardant composition of the class mentioned in the preamble which is characterized in that it consists essentially of at least one water-soluble flame-extinguishing agent, at least one water-soluble swelling agent and, at least one water soluble complexing agent, in addition to an aqueous solution of the composition, as well as, optionally, a water soluble carbonizing agent.
  • the flame arresting agent is in a concentration range of 50 to 90% molar, and preferably 60 to 80% molar.
  • the flame extinguishing agent is selected from the group of phosphates; such as ammonium hydrophosphate, and diamonium hydrophosphate.
  • the swelling agent is preferably chosen from the group consisting of: guanidine, hydrochloride guanidine, urea, glycine and other water-soluble amino acids as well as derivatives thereof such as amides, in a concentration range of 5 to 40% molar and preferably 10 to 30% molar.
  • the complexing agent is preferably selected from the group consisting of ethylenediaminetetraacetic acid (EDTA) and nitrile triacetic acid as well as its salts, which is used in a concentration range of 0.5 to 10 mol% and preferably 1 to 5% molar
  • the carbonizing agent is preferably chosen from the group consisting of a dextrin, glycerin, inositol, amylose, water soluble polysaccharides, pentaerythritol, dipentaerythritol and polyalcohols, used in a range of 0.1 to 30% molar and preferably 0.1 to 20% cool .
  • the gel-forming agent is preferably chosen from the partially intertwined potassium acrylate polymers and related substances within this group, used in a concentration range of 0.1% to 40% molar and preferably between 0.1 to 30% molar.
  • Another aspect of the present invention offers a process for the preparation of such a fire retardant composition
  • a process for the preparation of such a fire retardant composition comprising the dissolution in water of the chemical components in order to form an aqueous solution of said fire retardant composition and the isolation of the composition itself from of said mixture by evaporation.
  • the flame-extinguishing agent, the agent is added consecutively to the water complexing agent, the swelling agent and the gel forming agent, and optionally the. carbonizing agent
  • the flame-retarding agent is an ammonium hydrophosphate
  • it may itself be present in the form of ammonium hydrophosphate as well as in the form of ammonia and phosphoric acid to thus be added to the water, either each or both.
  • the achievement of the addition of salt and / or base and acid is not a critical factor here.
  • the solution is then neutralized with an inorganic acid such as hydrochloric acid or sulfuric acid so that the hydrogen potential (pH) is between 6.5 and 7.5.
  • agent should be understood as one or several mentioned members of the group; as a complexing agent, for example, ethylenediaminetetraacetic acid (EDTA) can also be applied, as well as nitrile triacetic acid and in this case the molar percentages mentioned refer to the total of the components of the group.

  • the aqueous solution of the composition according to the invention shows surprisingly good properties.
  • the material of any type such as metal, plastic, wood, treated with the aqueous and gelled solution of the composition and which comes into contact with a fire, does not burn and also has quenching properties, so that in addition to said extinguishing a fire will also be impregnated by the environment so which will not spread the fire anymore.
  • the solution itself remains stable for years. It may also be evident that the fire retardant composition as well as its solution in water complies with the Sweden Convention on "Persistent Organic Pollutants (POP 's)
  • the solution obtained is applied in a thin layer on the surface of the material to be protected, the absorption of which will depend on the type of material.
  • the material in which it was applied will retard the onset of combustion up to an hour and a half in the case of wood; and in the case of cloth subjected to the heat of a torch at 1,800 degrees, it retards the onset of combustion up to 2 minutes.
  • the formula should have the following agents: Flame retarding agent, swelling agent, complexing agent, carbonizing agent and a gel forming agent.
  • the experimental phase was initiated with a low percentage of the flame retardant agent, initially including only ammonium hydrophosphate, however and after chemical analysis of said composition and a trial and error process, the decision was made to include in the formula the diamonium hydrophosphate. Bliss combination resulted in a much more effective and efficient flame retardant.
  • the swelling agent it was decided to use urea at first, since when exposed to heat, nitrogen gas is released which creates an inert layer to the fire, also protecting the treated material from fire.
  • the percentage of swelling agent to be used was also varied in terms of the molar of the final formula to arrive at the preferable combination between swelling agent and fire retardant agent. Upon reaching the ideal combination between said agents, a complexing agent was also added to shape the final product.

Abstract

La présente invention concerne une composition chimique aqueuse et gélifiée ignifuge conçue précisément pour retarder le de déclenchement de la combustion dans des conditions favorables aux incendies. La composition décrite dans cette invention se caractérise en ce qu'elle comprend au moins un agent extincteur de flammes soluble dans l'eau, au moins un agent expansible soluble dans l'eau et au moins un agent formateur de complexes soluble dans l'eau, en plus de la solution aqueuse de la composition et, éventuellement, un agent de carbonisation soluble dans l'eau. La solution ainsi obtenue est appliquée en couche mince sur la surface du matériau à protéger et dont l'absorption dépend du type de matériau; une fois le produit absorbé, le matériau sur lequel est appliquée la solution peut être exposé à une source de chaleur pendant 30 minutes à une heure, en fonction du matériau concerné, avant le début de la combustion.
