Abstract
Description
- This application is the U.S. National Phase Application under 35 U.S.C. § 371 of International Application No. PCT/ES2018/070547, filed Aug. 6, 2018, designating the U.S. and published as WO 2020/030830 A1 on Feb. 13, 2020.
- The present invention relates to the sector of fireproof compositions.
- In recent years, forest fires, domestic fires and fires in industrial and livestock installations have increased in number and intensity. Accordingly, in recent years a large number and variety of fire protection compositions have been developed.
- The increase in the security of the products used against fires has meant that new compositions with fireproof properties are being developed. However, it is known that many chemical fireproof products contain components that may be toxic to human beings and are damaging to the environment.
- The present invention relates to the sector of fireproof compositions and more particularly to a composition for fire protection that produces a carboxylic layer on coming in contact with fire, to a method for preparing said composition and to different uses thereof.
- The use of compositions that contain sugars as fireproofing agents and fire protection agents is known (see, for example, the publications of PCT WO2008058324A1, European patent EP1853358B1 and South Korean patent KR20080001702A). Thus, the publication of Korean patent KR20080001702A discloses a flame retardant that forms a carboxylic layer which comprises sugar or graphite and a flame retardant chosen from monoammonium phosphate, diammonium phosphate, ammonium polyphosphate and melamine phosphate. However, said fireproof compositions also contain sugars, surfactants, phosphates and other agents that are toxic to human beings and damaging to the environment. Moreover, preparing and using said compositions in some installations is normally problematic owing to the noxiousness and corrosiveness thereof. In addition, the presence of phosphates means that said compositions are very corrosive, which creates storage problems and causes damage to objects following application thereof.
- Furthermore, the publication of British patent GB190023890A in 1901 describes an acid-resistant cement for application to protect objects made of cardboard, wood or metal, and particularly for electrical use, which consists of a composite cement comprising magnesium oxychloride, Portland cement and molasses. Said magnesium oxychloride is formed by mixing magnesium oxide and a solution of magnesium chloride, while the molasses are used to dilute the cement. This cement cannot be applied to people or animals owing to the toxicity and corrosiveness of magnesium oxychloride, nor does it form a carboxylic protection layer. In addition, hardening owing to the presence of cement makes its use for extinguishing fires inadvisable, and does not permit extended storage prior to use. Moreover, it cannot be used in fluid installations and or applied to objects without causing irreparable damage.
- When fighting forest fires, aeroplanes, particularly tanker aeroplanes, which in many cases are adapted hydroplanes, are used. The chemical products used to combat said fires may include water, water enhancers such as foams and gels, and in particular specially formulated flame retardants. However, the high density of these fireproof compositions limits aeroplane loads.
- An additional problem with all the above-mentioned compositions is that the freezing point thereof is equal to or higher than 0° C., leading to storage problems in winter.
- To sum up, the compositions known at present have the following drawbacks:
-
- they are highly corrosive
- they produce salt precipitations over time.
- This means said compositions cannot be stored for an extended period of time, or used in fluid installations for extinguishing fires, as said compositions would cause corrosion in the installation and/or blockages owing to the precipitates produced.
- Moreover, in some cases the known compositions are only stable under very specific and controlled environmental conditions. Extreme conditions of cold or heat, for example, which occur in summer and/or in winter cannot be withstood.
- In view of the above, there is still a need for effective fireproof compositions to reduce and/or eliminate the use of compositions that are damaging to human beings or the environment, are stable over a wide range of temperatures, do not precipitate significantly over time and are not corrosive.
- The object of the present invention is to disclose compositions that allow a solution to the above-mentioned problems. Accordingly, a fireproof composition that does not require the presence of toxic components has been developed. The present invention is based on components that are suitable for food use, are biodegradable and do not contaminate the environment. The novel composition acts as a fire blocker.
- The present invention discloses a fireproof composition for application to products to protect against fire, which is constituted as an aqueous composition comprising at least one sugar and magnesium chloride. Preferred embodiments of the invention may be applied to animals and people without risk to their health.
- In the present invention, the term “sugar” refers to a compound formed of carbon, hydrogen and oxygen, in which the formula Cn(H2O)n applies to the composition thereof. Sugars are generally classified as monosaccharides, disaccharides or trisaccharides.
- Being aqueous based, the composition of the present invention allows for the magnesium chloride and sugar in contact with flames to form a carboxylic layer which increases in size and protects the object to which the composition is applied. It is therefore a fire blocker.
- The composition of the present invention has many advantages. Moreover, the composition is not corrosive and does not precipitate. The composition according to the present invention has a low freezing point, being stable between −30° C. and 70° C. This facilitates the storage of the composition in tanks, pipes, etc. without the need for mechanisms to prevent freezing (heating, recirculation pumps) with the consequent saving in energy. Moreover, it has a high insulating capacity, which allows application to latex, expanded polyurethane, physical persons and many objects. Furthermore, it is a composition that has the ability to adhere very well to surfaces. In addition, it is a non-contaminating product as no component thereof is a toxic product. The product may be eliminated by washing with abundant water.
- Magnesium chloride has the property of being a hygroscopic compound, and therefore absorbs humidity and prevents the composition from becoming dehydrated. The longevity of the substance is thus extended once applied to the object, person or animal to be protected. The composition remains on the object to which it was applied, protecting said object from possible fire until said composition is eliminated.
- Furthermore, the stability over a wide range of temperatures, non-corrosiveness and lack of precipitations of said substance also make said substance very suitable for storage waiting to be used to extinguish fires. The viscosity thereof is similar to that of water. In particular, the composition may be stored without damaging pipes, tanks and/or fluid impeller pumps.
- In the present invention, the sugar is preferably selected from the group consisting of fructose, dextrose, glucose, sucrose, maltose and isomaltose, and sugars contained in molasses. Sucrose is commonly known as “table sugar” or “ordinary sugar”.
- In the present invention, the term “molasses” refers to a final sub-product of sugar manufacture or refining. It is a dense, viscous liquid which is separated from the low purity massecuite by centrifugation.
- Preferably, said sugar has a concentration of between 150 g/l and 1000 g/l in the composition. More preferably, said sugar has a concentration of between 200 g/l and 400 g/l in the composition.
- Preferably, said magnesium chloride has a concentration of between 50 g/l and 580 g/l in the composition. More preferably, said magnesium chloride has a concentration of between 150 g/l and 400 g/l. More preferably, said magnesium chloride has a concentration of between 200 g/l and 300 g/l.
- Preferably, said composition also comprises a corrosion inhibitor. Said corrosion inhibitor makes it possible for the composition to be applied to any type of object. An example of a corrosion inhibitor might be ethanolamine. The use of any other corrosion inhibitor is also possible, preferably chosen from natural or ecological corrosion inhibitors (also known as eco-friendly inhibitors). In a particularly advantageous way, the corrosion inhibitor will be a deoxygenator.
- Preferably, said composition has a final pH of between 6.0 and 7.5. Accordingly, the composition may also comprise a pH regulator. In some applications, the corrosion inhibitor may be suitable for adjusting the pH to the required range on its own.
- Preferably, the fireproof composition comprises exclusively components that are innocuous to human beings. More preferably, said composition is free from halogen atoms, particularly fluoride or bromine atoms, and from sulphate or phosphate atoms, among others. In this way, the innocuousness of the composition to animals and people is ensured, which allows both application to people and animals, and ingestion of said composition.
- In one embodiment, the inventors of the present invention have developed a composition specifically for this use which, in addition to magnesium chloride and at least one sugar, comprises light magnesium carbonate. A person skilled in the art will understand that when light magnesium carbonate is mentioned, it refers to hydromagnesite (4MgCO3.Mg(OH)2.4H2O). Said light magnesium carbonate reduces the density of the fireproof composition and therefore makes transportation in the hydroplanes and helicopters used to extinguish fires such as forest fires particularly advantageous. The density of the composition will preferably be between 0.8 kg/l and 1.1 kg/l. Densities lower than that of water may be achieved with the help of light magnesium carbonate. For aeronautical applications, it will be particularly preferable for the density of the composition to be between 0.8 kg/l and 0.85 kg/l.
- Furthermore, the composition can be applied to the forest cover and in particular to any type of plantation with no effect on either the plant or the edibility thereof.
- In some applications, particularly those that use molasses, the composition of the present invention, said sugar and said magnesium chloride are in a proportion between 1:0.65 and 1:0.75, respectively. In other embodiments, said proportion is between 1:0.8 and 1:1.1, more preferably 1:1.
- In a particularly preferred embodiment, the composition according to the present invention contains exclusively water, sugars (including commercially available sugars) and magnesium chloride, and, optionally, a corrosion inhibitor, a pH regulator, and/or light magnesium carbonate and/or a colorant.
- Furthermore, the present invention discloses a method for preparing the fireproof composition for application to products to protect against fire mentioned above, which is constituted as an aqueous composition, characterised in that it comprises the steps of:
-
- a) obtaining at least one sugar and magnesium chloride (MgCl2);
- b) dissolving the components of step a) in water; and
- c) adjusting the pH of the solution obtained in b) to between 6.0 and 7.5.
- Preferably, in said method it is also possible to add light magnesium carbonate in step a).
- Furthermore, the present invention discloses the use of the above composition for the prevention of damage caused by fire. Accordingly, the aqueous composition according to the present invention is preferably applied to the area and/or objects to be protected. The aqueous composition according to the present invention may be applied to any type of object such as electrical wiring, cardboard, wood or metal objects. Said composition may also be applied to animals, people and even buildings.
- The composition according to the present invention may also be used to extinguish fires, by applying said composition directly to the flames. However, owing to the aqueous nature thereof, said composition is not suitable for fires involving liquids with a lower density than water.
- In addition, the present invention discloses the use of the above composition for extinguishing forest fires using aeroplanes, hydroplanes or helicopters. In this case, the hydroplane will be loaded with the substance according to the present invention and will release said substance over the area affected by fire. For this use, it will be preferable for the composition to have a low density, so that a greater volume thereof can be transported.
- The present invention also discloses the use of the composition according to the present invention for extinguishing any type of fire, preferably industrial and/or domestic fires, by the application of the composition using fluid installations that have pipes and pumps, such as fire engines and motor pumps. For this use, the lack of corrosiveness of the composition according to the present invention is particularly useful, as is the fact that said composition does not precipitate, which allows the composition to be kept in the installation over a long period, waiting until required for use.
