Otro requisito que se pide de la composición que habrá de desarrollarse es que sea gentil frente al medio ambiente. En la Patente Norteamericana 6' 911, 070 se describe una dispersión coloidal retardadora de incendio de celulosa en agua y ácido fosfórico. En la aplicación de tal composición se liberan gases como el amoniaco que constituyen un peligro para la salud humana. Además acarrea la aplicación de una dispersión coloidal con ciertos problemas específicos como por ejemplo el riesgo de hundimiento y de un comportamiento dependiente de la temperatura .Another requirement that is required of the composition to be developed is that it be gentle towards the environment. In US Patent 6 '911, 070 a fire retardant colloidal dispersion of Cellulose in water and phosphoric acid.

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
Cuando el agente apagador de flamas sea un hidrofosfato de amonio, él mismo puede estar presente en forma de hidrofosfato de amonio como también en forma de amoniaco y ácido fosfórico para agregarse así al agua, ya sea cada cual o ambos. La consecución de la adición de la sal y/o base y ácido no constituye aquí un factor crítico.

La solución acuosa de la composición de acuerdo con el invento muestra propiedades sorprendentemente buenas. El material de cualquier tipo como por ejemplo metal, plástico, madera, tratado con la solución acuosa y gelificada de la composición y que se pone en contacto con un fuego, no se quema y también tiene propiedades de apagar, de manera que además de dicha extinción de algún incendio también será impregnado el medio ambiente por lo cual no se propagará más el incendio. La propia solución permanece estable durante años . Además puede ser evidente que la composición retardadora de incendio así como su solución dentro de agua cumple con el convenio de Estocolmo acerca de "Persistent Organic Pollutants (POP' s)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 Stockholm Convention on "Persistent Organic Pollutants (POP 's)
(Contaminantes Orgánicos Persistentes) , que está en vigor desde el 17 de mayo de 2004, cuyo propósito es excluir las impurezas orgánicas persistentes.(Persistent Organic Pollutants), which has been in effect since May 17, 2004, whose purpose is to exclude persistent organic impurities.
Forma de utilizar el producto. La solución obtenida se aplica en capa delgada sobre la superficie del material que se pretende proteger cuya absorción dependerá del tipo de material.How to use the product. 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.
Una vez absorbido el producto, el material en el que se aplicó retardará el inicio de la combustión hasta en una hora y media tratándose de madera; y tratándose de tela sometida al calor de un soplete a 1,800 grados, retarda el inicio de la combustión hasta 2 minutos.Once the product is absorbed, 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.
Para llegar a la composición química a que se refiere la presente invención se examinaron diferentes combinaciones de los distintos agentes que la componen. La formula debía contar con los siguientes agentes : Agente retardador de llamas, agente hinchador, agente formador de complejos, agente carbonizante y un agente formador de gel .In order to arrive at the chemical composition referred to in the present invention, different combinations of the different agents that compose it were examined. The formula should have the following agents: Flame retarding agent, swelling agent, complexing agent, carbonizing agent and a gel forming agent.
Se inició la fase experimental con un porcentaje bajo del agente retardador de llamas, incluyendo en un inicio únicamente el hidrofosfato de amonio, sin embargo y después de análisis químicos de dicha composición y de un proceso de prueba y error, se tomo la decisión de incluir en la formula el hidrofosfato de diamonio. Dicha combinación resultó en un retardante de flama mucho mas eficaz y eficiente.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.
En cuanto al agente hinchador se decidió utilizar de inicio la urea dado que al ser expuesto al calor se desprende gas nitrógeno el cual crea una capa inerte al fuego protegiendo también al material tratado del fuego. El porcentaje de agente hinchador a utilizar se varió también en cuanto al molar de la fórmula final para llegar a la combinación preferible entre agente hinchador y agente retardante de fuego. Al alcanzar la combinación ideal entre dichos agentes se agregó también un agente formador de complejos para dar forma al producto final.As for 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.
Para la protección en telas y materiales más fáciles de incendiar se observó en las pruebas iniciales que era necesario agregar un agente carbonizante que creara una capa carbonizada de protección. Al agregar dicho agente se crea una capa que ayuda en la exposición directa a una flama. El porcentaje de agente carbonizante se logró ajustar después de probar el producto aplicado en tela de algodón y su respuesta al fuego. For the protection of fabrics and materials that were easier to catch on fire, it was observed in the initial tests that it was necessary to add a carbonizing agent that created a carbonized protective layer. By adding such agent a layer is created that helps in direct exposure to a flame. The percentage of carbonizing agent was adjusted after testing the product applied in cotton cloth and its response to fire.
