Definitions
- the invention relates to a fire extinguishing composition for use in all types of fires, in particular in metal and forest fires.
- Fires are divided into four main classes, A, B, C and D, according to the source of the fire, the type of combustible material and the way the fire spreads.
- Class A is used for solid material fires
- Class B for liquid material fires
- Class C for gas fires
- Class D for metal fires.
- Water is the most commonly used substance to extinguish forest and Class A fires in the world.
- water-expanding products (foam) are widely used for this purpose.
- the temperature reaches 1000 degrees Celsius.
- the water used against fires at this temperature starts to boil at 100 degrees Celsius and evaporates, while the hydrogen in its structure evaporates at 108 degrees Celsius and the remaining oxygen further triggers combustion. For this reason, extinguishing fires at high temperatures and in windy weather with water takes a long time and the failure rate in the extinguishing process increases.
- Foams dry and disappear in the face of high heat.
- the extinguishing process is aimed at covering the burning material and cutting its contact with oxygen. If the burning substance cannot be completely covered, the extinguishing process cannot be successful.
- Foam products do not have the feature of "preventing and delaying flame spread" and cannot be used by helicopters and airplanes due to their light weight. However, they can be used in hydrocarbon combustion (Class B) because they cover the surface like a blanket and cut off oxygen.

- Said extinguishing agent is made of a mixture of 20-200-micron boron oxide and hydrophobic glass beads. In this case between 70 and 95% boron oxide is used.
- the glass spheres used are so-called cenospheres (waste materials from coal combustion), which naturally fluctuate greatly in their properties and work in an uncontrolled reactive manner. These particles are hydrophobized to prevent them from sticking to the application apparatus used.

Description
A Fire Extinguishing Composition
Technical Field
The invention relates to a fire extinguishing composition for use in all types of fires, in particular in metal and forest fires.
Prior Art
Fires are divided into four main classes, A, B, C and D, according to the source of the fire, the type of combustible material and the way the fire spreads. Class A is used for solid material fires, Class B for liquid material fires, Class C for gas fires and Class D for metal fires.
In the world, water is generally used to extinguish forest fires. Water-expanding chemical foams, on the other hand, dry out in the face of high heat and cannot be used by helicopters and airplanes due to their light weight. (However, they can be used in hydro carbon combustion (Class B) as they cover the surface like a blanket and cut off oxygen). In forest fires, the temperature reaches 1000 °C. The water used in fires at these temperatures evaporates at 100 °C, hydrogen evaporates at 108 °C, the remaining oxygen triggers combustion, and the foam dries.
Light metal aluminium, lithium, magnesium, titanium, zirconium, zinc, barium, uranium, plutonium, sodium, potassium and calcium etc. cannot be easily extinguished with their temperatures reaching up to 1000°C in metals that start with internal combustion. In metal fires known as class D fires, pure water and dry chemical powders such as ABC /BC cannot be used due to their low melting temperatures. However, it can be extinguished by covering it with substances that will form a thick layer and cutting its contact with oxygen.
Water is the most commonly used substance to extinguish forest and Class A fires in the world. In addition, water-expanding products (foam) are widely used for this purpose. In forest, industrial or residential fires, the temperature reaches 1000 degrees Celsius. The water used against fires at this temperature starts to boil at 100 degrees Celsius and evaporates, while the hydrogen in its structure evaporates at 108 degrees Celsius and the remaining oxygen further triggers combustion. For this
reason, extinguishing fires at high temperatures and in windy weather with water takes a long time and the failure rate in the extinguishing process increases.
The other most commonly used material in such fires is water-expanding foam products. Foams dry and disappear in the face of high heat. The extinguishing process is aimed at covering the burning material and cutting its contact with oxygen. If the burning substance cannot be completely covered, the extinguishing process cannot be successful. Foam products do not have the feature of "preventing and delaying flame spread" and cannot be used by helicopters and airplanes due to their light weight. However, they can be used in hydrocarbon combustion (Class B) because they cover the surface like a blanket and cut off oxygen. In addition, Perfluorooctane sulfonate (PFOS) and Perfluorooctanoic acid (PFOA) substances in AFFF ("Aqueous Film Forming Foam) foam structures have toxic effects. The report on toxicity was published by the EPA (United States Environmental Protection Agency) in 2016.
In the prior art, flame retardants are used as fire prevention and retardants. As the name suggests, these retardants are used only as "flame retardants". They have no extinguishing effect and limited cooling effect. The main ingredient of commonly used retardants is ammonium phosphate dibasic. Phosphate dibasic has been declared by the World Health Organization to emit irritating or toxic fumes (or gases). It is also ineffective at temperatures as high as 1000°C as its melting temperature is 155°C.
Light metal aluminium, lithium, magnesium, titanium, zirconium, zinc, barium, uranium, plutonium, sodium, potassium and calcium etc. cannot be easily extinguished with their temperatures reaching 1000°C in metals that start with internal combustion. Water and dry chemical powders such as ABC /BC cannot be used in these (class D) fires. However, it is extinguished by covering it with substances that will form a thick layer and cutting its contact with oxygen, and for these reasons, light metal fires constitute a separate extinguishing class as class D.
Patent document coded 2023374 in the prior art mentions a dry powder fire extinguishing agent containing different powders (carbonates, borax, magnesium oxides, etc.) to be applied by means of adhesives. The main component is perlite. Perlite is extremely hygroscopic, with a limited shelf life. In addition, a "waterbased adhesive" should be used as it has a very large active surface. However, in case of fire, this can act as an oxygen reservoir for fire and especially for more fuel metal fires. These adhesives are in powder form and must be melted in a fire, thus bonding the powder.
The patent document EP0395322B 1 in the prior art mentions a metal fire and a related extinguishing agent and extinguishing method. Said extinguishing agent is made of a mixture of 20-200-micron boron oxide and hydrophobic glass beads. In this case between 70 and 95% boron oxide is used. The glass spheres used are so- called cenospheres (waste materials from coal combustion), which naturally fluctuate greatly in their properties and work in an uncontrolled reactive manner. These particles are hydrophobized to prevent them from sticking to the application apparatus used. However, the extinguishing powder according to the invention is not "stickable" and is therefore only suitable for horizontal fires.
The US patent document coded US3475322 in the prior art mentions a powder mixture of metallophilic compounds such as SiC and zirconium boride. The mixture is used in combination with hollow glass spheres with a size of less than 35 pm. All materials described in the document are covered by a single class of extinguisher.
The German patent document coded DE 102006019739 in the prior art refers to a "temperature resistant" round granule and a "spray system". The product in question uses a combination of a cetosphere and borosilicate glass. It is important that the glass granules have a minimum of 10% alumina, better >30%. Ideally, only borosilicate glass is used.
The German patent document coded DE 102016011955 in the prior art mentions a product developed with glass silicates and phosphates. The document suggests heating the product with a heating aerosol. The patented fire extinguishing agent comprises temperature-resistant, hollow and round pellets in the form of hollow glass beads or hollow ceramic balls, in which the glass material contains silicon dioxide, aluminium oxide and ferric oxide.
The American patent document coded US2349980 and the Chinese patent document coded CN101073696, which are included in the prior art, mention an incendiary bomb. It is formed at a distal end of the detonation mechanism with an enlarged head portion having a truncated cone-shaped edge counteracting the explosive powder and, at its end, is adjacent to the explosive mechanism by a peripheral mechanism presenting opposite inclined edges to the segments. These body parts are adapted to direct the fire extinguishing powder particles when the device is detonated.
The above-mentioned documents in the prior art are far from rationality and practical use. They are not functionally effective for fire types with the same category (Class A and D), nor are they similar in content.
When water is generally used for fire extinguishing in the prior art, the desired extinguishing and cooling process cannot be fully achieved due to the 108° C evaporation of hydrogen at 100°C. Although the extinguishing process is carried out with water, it is not possible to prevent the fire from progressing and destroying large areas in terms of time.
Purpose of the Invention
The aim of the invention is to obtain a composition that ensures the precise and rapid extinguishing of all kinds of fires, especially forest fires, which are unstoppable and can last for months.
Another purpose of the invention is to provide a composition which eliminates the need for days of cooling after extinguishing.
Another aim of the invention is to obtain a composition that eliminates the reignition of forests and protects the ecological and economic order with the "counterfire" application applied in some fires that cannot be prevented in order to stop the spread that causes the fire to grow by creating a barrier.
Another purpose of the invention is to obtain a composition that can extinguish 400- 1600 °C high temperature and fire in class A and D fires in a very short time compared to water, water-expanding chemical foams and flame retardants.
Another purpose of the invention is to obtain a composition that keeps the area moister by creating surface tension with natural foam, and ensures that the fire is not carried beyond the applied boundary by forming a surface coating and film layer in surface applications.
Another purpose of the invention is to obtain a composition that can be used in powder or liquid form that can be used in all types of Class A and D fires by cutting off the oxygen that triggers combustion.
Another purpose of the invention is to obtain a non-flammable composition that does not emit toxic gases and fumes according to OSHA (Occupational Safety and Health Administration), NIOSH (National Institute for Occupational Safety and Health) and ASCEH ( Accommodation, Safety, Communication, Environment and Hygiene) standards and regulations, and thus can be applied without polluting the nature and risking human health.
Another purpose of the invention is to create fire safety by rapidly extinguishing and cooling the burning environment in fires intervened by fire fighters in industrial plants, houses and vehicles, and to obtain a composition that prevents the spread of fire and flame by using the fire and flame spread prevention feature of the invention in order to prevent the spread and spread of flames to additional buildings.
Another purpose of the invention is to obtain a composition suitable for the natural environment by using a plant species to reduce the surface tension, which contributes to the faster healing of the burned area.
Another purpose of the invention is to extinguish light metal fires in industry by decomposing the product in the face of high heat, by binding the crust and cutting off the oxygen, and to obtain a composition that terminates the combustion by cutting its contact with oxygen.
Another purpose of the invention is to obtain a composition that can be used as a powder and/or liquid (liquid) form as an instant-fast fire extinguishing agent in all fire extinguishing vehicles and equipment such as vehicles, helicopters, fire planes, fire water pools, fire water wells, mobile extinguishing tubes.
The composition developed to achieve the aforementioned purposes includes aluminium sulfate, DI Sodium Tetraborate Decahydrate (Na2B4O?10H2O), Soapwort- Giant fennel- Saponin (Saponaria officinalis) natural plant extract, Trihydrooxydoboron (BH3O3), inhibitor (O2 + N2H4) and Water (H2O).

Aluminium sulfate in the composition has a molar mass content thirty-six times higher than water. In its molar mass content, there is molecular water with high heat resistance. Molecular water can quickly extinguish burning objects with high heat. The mentioned aluminium sulphate is used in water treatment and cleaning processes. It is also used in agriculture to increase soil fertility and to adjust the PH level of the soil. By increasing soil fertility, it ensures the rapid regeneration of vegetation after fire.
Aluminium Sulphate in 100% powder form can be formulated in 60% liquid (liquid) forms by dissolving in hot water. Aluminium sulphate melts at temperatures of 400°C and above. With its high melting temperature, if it is applied on the burning object with a higher temperature than itself, a crust is formed with a sudden reaction (770 °C).
When aluminium sulphate is applied on any object, it forms a thin layer on the applied surface that does not deform quickly under normal weather conditions. When this applied surface is exposed to 400° C flame, it releases the molecular water in its structure with the effect of the heat generated.
When aluminium sulphate comes into sudden contact with high temperatures above 400°C, it decomposes and forms a heat-resistant crust layer. When applied to a fire burning with high heat, it forms a non-volatile and fire-resistant layer that does not evaporate quickly and stops the oxygen absorption that triggers combustion by cutting the contact of the fire with oxygen. In the composition, 1-60%, preferably 50-52% aluminium sulphate is used. The composition of the invention should contain at least 30% aluminium sulfate for use in metal fires.
In addition, thanks to the heat-resistant molecular waters, the surface is kept wet and burning is prevented. By applying the composition directly or in a diluted form on the fire and flame, a wetter and more humid structure than water is created. With the wet and moist structure, the fire can be extinguished very quickly. However, aluminium hydroxide (Hydrargilite) in the aluminium sulfate content in the composition has a cooling effect on fire and flame.
DI Sodium Tetraborate Decahydrate (Na2B4O710H2O) in the composition is a natural mineral that is strong against high temperatures. It has a boiling temperature of 1575°C. Thanks to its high boiling point, it does not bum itself in fires. In addition, the mentioned Di Sodium Tetraborate Decahydrate is a mineral with high molecular water. After 70° C, it breaks down at certain temperature intervals and releases molecular water to the outside. Extinguishing the fire is ensured by molecular water release. DI sodium tetraborate decahydrate is a powerful natural disinfectant with antiseptic, antifungal and antibiotic properties in addition to the properties mentioned above. With these properties, the rapid and healthy formation of vegetation after the fire is ensured. It does not cause environmental toxicological degeneration when used at a certain rate.
When DI Sodium Tetraborate Decahydrate (Na2B4O710H2O) is homogeneously formulated with aluminium sulfate in certain ratios and conditions, aluminium boron sulfate is formed. There is a lot of molecular water in aluminium boron
sulfate. Molecular water ensures that the composition is used as an effective extinguisher. Aluminium Boron Sulfate shows sequential function in contact with high temperature. Di Sodium Tetraborate Decahydrate, which decomposes at 70°C, binds with Trihydrooxy doboron, which decomposes at 170°C, and supports the dissolution integration of Aluminium Sulphate both in flame prevention and by lowering the PH level of 9.3.
When di sodium tetraborate decahydrate (Na2B4O?10H2O) in the composition is combined with aluminium sulphate in certain proportions, it decomposes under high temperature and starts to melt. It reacts with the contact of the burning-melting structure with oxygen from outside under high temperature where it is covered and sealed and pushes the substances in its content to form a shell. The formed crust is unable to pass oxygen from the outside, cools down from the inside with its smoke and heat absorbing properties and ends the combustion.
Saponin in the composition is a foaming agent. Saponin is the active ingredient of natural herbs such as soapwort, chokecherry or coffeeberry. Saponin is extracted from the woody roots of these plants. The composition with saponin provides a wetter/moist structure than water on both flat and intricate surfaces (Forest Vegetation, Automotive Tires, Wooden Pallets), reducing surface tension and forming foam.
The fact that the product within the scope of the invention forms a wetter and more moist structure than water both on flat and intricate surfaces (Forest Vegetation, Automotive Tires, Wooden Pallets) and on the surfaces applied according to the standard model is provided by Saponaria Officinalis-Sponin, a plant that reduces surface tension and forms foam.
Trihydrooxy doboron (BH3O3) in the composition melts at 170°C. Trihydrooxydoboron, a mineral acid, is used in flame prevention. This trihydrooxy doboron contains 18.01528 g/mol water. Trihydrooxidoboron is used as an extinguisher thanks to the amount of water it contains. In addition, the mentioned trihydrooxidoboron acts as an activator. Trihydrooxydoboron used as an activator is used to increase or initiate the reaction rate. In addition, the activator enables the quenching reaction to proceed more efficiently and controllably. In alternative embodiments of the invention, materials such as bentonite, poly ammonium phosphate, mono ammonium phosphate, di ammonium phosphate etc. can be used as activators.
The inventive composition decomposes with the release of molecular water resistant to 1600° C against high temperature. With the composition of the
invention, the factors that the applied area is wet with the release of molecular water of DI Sodium Tetraborate Decahydrate up to 1600 degrees Celsius, and that aluminium sulfate and boric acid become resistant to combustion with the cooling rate of aluminium sulfate and the compound formation of aluminium sulfate and boric acid are gathered in a single product.
The inventive composition dissolves with water at a rate of l%-60% in the production process. Dissolution ensures homogeneity of the composition. With a homogeneous mixture, the composition can be produced in concentrated form.
Due to its high water content molecular structure and low surface tension, the composition provides an intense wetness and high temperature resistant humidity on the applied surface. In addition, intense wetness and high temperature resistance ensure that objects exposed to high temperatures deflate much faster than normal water. In addition, thanks to aluminium hydroxide, which is the active ingredient of aluminium sulfate in the composition, it is ensured that the object resists heat and fire and cools quickly by forming a shell and film layer.
The aluminium sulphate in the composition of the invention has the properties of wetness and dampness with the release of molecular water at 400° C with high temperature, and decomposition at temperatures of 400° C and above. Thanks to the aforementioned properties, both extinguishing and cooling, as well as cutting off the oxygen by binding the crust, reducing the heat and preventing the fire from moving forward are provided.
The inventive composition comprises metal inhibitors with different variations. The suitability of the inhibitors is specifically determined according to the nature of the metals used. Inhibitor determination is determined according to the mass loss test. Inhibitors are used to prevent the destruction of acidic structures that may occur in metals. The amount and type of inhibitor is tested on metals such as aluminium, chromium, copper, iron, stainless steel, etc. The most effective ratio is used in the formula structure. The inhibitors used reduce and prevent the corrosive effect.
Inhibitors prevent the corrosive environment from reaching the metal by forming a protective, impermeable, barrier layer on the metal surface. For the formation of an effective barrier, the inhibitor must interact with the metal in a continuous, continuous manner without being reactive to the metal. With the inhibitor, the composition can be used effectively in metal fires.
The inventive composition is also used for extinguishing internal combustion light metal fires characterised as class D. The composition is also used in extinguishing
and cooling class D fires, since it has heat and flame inhibiting, blocking, crust binding and deoxygenating properties.
A colouring pigment is used in the inventive composition. Preferably iron oxide is used as the colouring pigment. Iron oxides are available in four basic colours, namely yellow, red, brown and black, and are used to provide colouring to define the area to which the inventive composition is applied. According to one embodiment of the invention, the aqueous solution of the inventive composition comprising iron oxide colours the area to which the composition of the invention is applied from the air, so that the area is/appears to be defined. In alternative embodiments of the invention, different colours and types of pigments may be used.
In the inventive composition, water is used to ensure homogenous preparation of said composition.
Examples of different applications of the composition subject to the invention are given below.

Heptane of combustible material quality was ignited. The combustible material was allowed to burn for two minutes and the tray was withdrawn. In this way, the combustible material was expected to burn for 6 more minutes. It was observed that the prepared combustible material turned into embers. After this minute, the product was applied to the burning object in the fire extinguisher tube as much as the amount of filling amount specified in the standard (6 litres).
In practice, it was observed and recorded and documented that the patented product extinguished the fire quickly and instantaneously, that the temperature dropped below 60 C by measuring the temperature with a digital heat meter after 30 seconds, that the burning combustible material could be held with bare hands within 1 minute, and that there was no re-ignition of the combustible material 3 minutes after the extinguishing process according to the standard model.
Application 2;
The inventive composition was added 5% into normal water. As the concentration of the inventive composition in the applications increases, its effectiveness increases. Soaked pine tree with high coniferous pine. 24 hours were waited. After 24 hours, straw and dry bushes were placed under the tree to ignite and tried to ignite. However, there was no ignition. A torch was shone on thin branches. However, no combustion occurred. These works were recorded and documented on the Official Document.
Application 3;
Water was placed in one of the two hollow metal containers and the inventive composition in the other and heated at the same temperature. The water evaporated and disappeared and the composition formed a shell. Direct fire was continued to the local area in the shell structure. Corrosion was observed in the local area (above 400° C) The heat was removed and hand contact was made. No heat was observed on the surface (25° C with thermometer).
Application 4;
The application was made with car and truck tyres. The heat value of the ignited tyres was measured as 800 C with a thermal camera. The tyres were treated with the composition of the invention. It was measured that the temperature dropped to 50 C 1 minute after the application.
Application 5;
In the application, aluminium powder, a light metal, was ignited with a flame source. It was heated with water. The surface was sprinkled with the inventive composition. The surface was encrusted and the combustion was terminated.
The inventive composition comprises aluminium sulphate, di sodium tetraborate decahydrate, saponin, activator, inhibitor, pigment and water. The composition in the preferred embodiment of the invention includes
1-60% aluminium sulphate by weight,
1-3% inhibitor by weight,
0.1-0.3 wt.% pigment by weight and
1-40% water as the rest.
In a different embodiment of the invention for 1 litre of composition;
10-600 grams of aluminium sulphate,
1-3 grams of inhibitor,
0,1 -0,3 grams of pigment,
The liquid mixture can be prepared so as to have the rest of the water.
In alternative embodiments of the invention, in addition to the above composition; it contains
1-5 wt% di sodium tetraborate decahydrate,
1-3 wt% saponins and
0.1-0.4 wt.% activator components.

The composition is ten times more powerful than water and water-expanding chemical-containing foam in extinguishing the fire in advanced, accelerated, unstoppable, inextinguishable fires, and five times more powerful than flame retardants in stopping the fire, creating a barrier, and preventing spread (according to melting point).
The inventive composition can extinguish objects under the combustion temperature of 400-1600 °C by cutting the bond with oxygen. Thanks to the molecular water in the composition content, it can stay on the surface longer than water. In this way, re-ignition and flammability are prevented. The composition lowers the surface tension, resists heat and fire, prevents the propagation and allows the fire to cool down.
The inventive composition is prepared at a temperature of 80 °C. When the temperature is increased, the dissolution rate also increases. In order to achieve the same amount of dissolution at lower temperatures, longer mixing and additional processing is required. A temperature of 80°C was preferred to provide appropriate time and saturation. In alternative embodiments of the invention, production can be carried out at different temperatures.
Maximum 60% aluminium sulphate can be used at 80°C. Excess aluminium sulphate collapses. As the amount of aluminium sulphate used in the inventive composition increases, the effectiveness in extinguishing, cooling and barrier formation also increases. For example, the effectiveness of a composition in which 50% aluminium sulphate is used is higher than the composition in which 40% aluminium sulphate is used.
