Description

A suffocation fabric for fire suppression}

The present invention relates to a suffocating cloth for fire suppression, and more particularly, in case of a vehicle fire or oil fire, the fire source is suffocated by blocking contact with air to prevent the fire source from expanding due to contact with air. It relates to a suffocating cloth for fire suppression that is prepared to be safely extinguished, ensures the safety of firefighters who operate the suffocating cannon when extinguishing a fire, and can prevent the fire from spreading to the surroundings.

In general, when a fire occurs, a fire extinguisher is used as a normal fire extinguishing equipment or water is put out at a point where the fire has occurred to extinguish the fire. However, the use of these fire extinguishers or water must be selected and used according to the type of fire. In the case of an oil fire that can occur in a home, there is a problem in that the fire spreads further if water is used to extinguish the fire. If the size of the fire is small or a dedicated fire extinguisher, it is taught to extinguish the fire by blocking the fire source and air using a cloth such as a blanket.

However, if a blanket is used in such a fire suppression, if the temperature of the fire source is high or has already expanded, the blanket acts as a combustible material, leading to the expansion of the fire rather than the fire suppression, as well as the problem of blanket combustion It promotes the generation of harmful gases, resulting in safety problems.

On the other hand, in the case of a special fire such as a vehicle fire, firefighters are extinguishing the fire by directly spraying a fire extinguishing liquid on the vehicle. However, the vehicle has an oil tank where oil is stored, and various devices and combustion materials for vehicle operation are mounted, so there is a risk of explosion, and such risk factors pose a great threat to the safety of firefighters who spray fire extinguishing fluid directly into the vehicle. This is what is happening. Moreover, there is a problem in that harmful gases generated as vehicles are burned pollute the atmosphere, damage surrounding facilities due to high temperatures and explosions, or spread fire to surrounding facilities.

In other words, general fires can be extinguished with a fire extinguisher or an extinguishing fluid such as water, but in the case of special fires such as automobile fires and oil fires, fire suppression is essential for the safety of firefighters, prevention of fire spread to nearby facilities, and minimization of harmful gas generation. There is a need for a suffocation cloth for this. In particular, since it can cause secondary environmental pollution due to fire extinguishing fluid, the use of such a suffocating cloth can limit the use of fire extinguishing fluid, thereby preventing environmental pollution caused by fire suppression, and cleaning up the surroundings due to the restriction on the use of fire extinguishing fluid. Demand for suffocation cloths is increasingly demanded because there is no need to make unnecessary efforts for this.

However, there is no technology disclosed as a suffocating gun for fire suppression yet, and what is being implemented is 1) Republic of Korea Patent Publication No. 10-2013-0001464, published on January 04, 2013. Fireproof blanket with excellent heat resistance and its manufacturing method, 2) Republic of Korea Utility Model Registration No. 20-0259099, registration date December 17, 2001. Fireproof fabric woven with carbon fiber yarn and glass fiber yarn, 3) Republic of Korea Patent Application No. 20-1987-0000875, filed on January 26, 1987. Extinguishing tool that looks like a quilt, 4) Korean Patent Publication No. 10-2020-0073883, published on June 24, 2020. Fire extinguishing blankets and the like are disclosed.

Here, the prior art disclosed at No. 1 is a fire-resistant fabric technology, and is configured to serve as a fire protection suit for protecting people from fire or a blanket prepared to prevent evacuees from being exposed to fire. The configuration is a fireproof blanket comprising a first heat-resistant layer made of silica fibers and a heat-resistant resin composition, a second heat-resistant layer made of a heat-resistant resin composition containing a flame retardant and a smoke suppressant, and an aluminum film, which is used for substantially suppressing fire. Rather, it is used to protect people from fire, so it is not suitable for general fire suppression or special type of fire suppression such as vehicle fire or oil fire. In general, silica fibers are also called glass fibers and can be used at a high melting point of about 1500 ° C., but there is a problem in that a large amount of dust is generated when in direct contact with a fire source for fire suppression. In addition, this dust has a problem of being accumulated in the lungs and acting as a harmful element when a person inhales dust in the form of a hook, so it is used for protecting the human body from fire, not for fire suppression.

On the other hand, the technique disclosed in No. 2 is also not significantly different from the technique No. 1 described above. In other words, it is used as protective equipment to protect evacuees from fire, not for fire suppression, and in the case of carbon fiber, the price is high and the economic burden can be increased. It is not suitable for use for the same special fire suppression.

The technology disclosed in No. 3 is actually used for extinguishing the fire by directly putting it into the fire. By inserting fire extinguishing powder, etc. in the quilted space and directly injecting it into the fire source, the quilted blanket is burned while the quilted space is burned. It is configured to extinguish the fire in the form that the fire extinguishing powder embedded in the inside is put into the fire source. However, this also does not solve the problem that the quilted blanket is first burned before the fire extinguishing powder is discharged to the outside, which causes a large amount of harmful gas to be generated and the fire to spread to the surrounding facilities.

The technology disclosed in No. 4 most recently relates to fire fighting blankets. The above technology is a form of extinguishing a fire by absorbing oil suitable for an oil fire so that there is no fuel to be burned. However, this also does not block air, so the effect is virtually insufficient, and a large amount of toxic gas is generated during the fire process, and it does not substantially affect the safety of firefighters.

That is, suffocation cloth for suppressing fire has not yet been disclosed in Korea, and the situation is focused on simply suppressing fire through fire extinguishing liquid or powder. Moreover, since the technology has been disclosed only from the viewpoint of protecting the human body through heat-resistant fabric, it is urgent to develop a suffocation cloth capable of suppressing harmful gas generation and rapidly extinguishing, along with the safety of firefighters who extinguish fires such as vehicle fires.

Although some of these suffocating guns for fire suppression are currently being disclosed overseas, they are quite expensive and still have safety problems due to a configuration unrelated to the safety of firefighters.

1) Republic of Korea Patent Publication No. 10-2013-0001464, published on January 4, 2013. 2) Korean Utility Model Registration No. 20-0259099, registration date: December 17, 2001. 3) Republic of Korea Patent Application No. 20-1987-0000875, application date: January 26, 1987. 4) Republic of Korea Patent Publication No. 10-2020-0073883, published on June 24, 2020.

Therefore, the present invention was created to solve the above-mentioned problems, and it is possible to secure the safety of firefighters in the process of suppressing the generation of harmful gases and suppressing the fire with respect to special fires such as vehicle fires and oil fires, and harmful dust, etc. The purpose is to provide a suffocating cloth for fire suppression that is harmless to the human body because there is no occurrence of fire and can rapidly extinguish a fire through perfect blocking of air and a fire source.

In addition, the present invention can minimize economic loss due to fire by preventing the fire from spreading to surrounding facilities due to a special fire, preventing environmental pollution caused by spraying fire extinguishing fluid, and reducing the input of unnecessary manpower to clean up the surroundings. Another purpose is to provide a suffocating cloth for fire suppression that can be prevented.

In order to achieve the above object, the fire suppression suffocation cloth according to the present invention is formed of inorganic fiber fabric for fire suppression that is woven in a twill weave and formed in any one shape among square, circular, and polygonal shapes. a suffocation cloth (100); 0.8% by weight of magnesium oxide, 27.2% by weight of silicon oxide, with respect to 100.0% by weight of the ceramic flame retardant coating solution coated on the upper and lower surfaces of the fire retardant cloth 100 formed of the inorganic fiber fabric for fire suppression, and 27.2% by weight of silicon oxide as a binder to prevent cracking and improve flame retardancy of ceramics. A flame retardant coating layer 110 formed by coating a ceramic flame retardant coating solution consisting of 6.0% by weight of an amino alkyd resin, 17.0% by weight of ceramic to which a fiber penetrant was added, and 49.0% by weight of water for a fire retardant coating layer 110; The formed asphyxiation cloth 100 is formed of basalt fibers, and is applied to the upper and lower surfaces of the twill-weave basalt fibers with ceramic flame retardant coating aqueous solution to form a flame retardant coating layer 110. Provided with basalt fibers The thickness of the asphyxiating cloth of inorganic fiber fabric is formed to 0.4 ± 0.05 mm through a compression step after forming a flame retardant coating layer, and ceramic is 9.0% by weight of 17.0% by weight of ceramic to which the fiber penetrating agent is added, and the fiber penetrating agent is nonionic. It is characterized in that it is 8.0% by weight of at least one selected from the group consisting of surfactant, benzene, carbon tetrachloride, n-tetradecane, and isopropyl alcohol.

Here, the amino alkyd resin is characterized in that it is obtained by polymerization of acrylic and ethylene-vinyl acetate copolymer (EVA).

On the other hand, the suffocation cloth 100 composed of the inorganic fiber fabric formed of the basalt fiber is formed with traction means 120 in four directions on a plane, and the traction means 120 has a traction ring 122 to 4 directions of the suffocation cloth. In order to maintain airtightness, it is sewn with Teflon yarn and twilled with basalt fiber to prevent breakage due to the tensile force of the suffocating fabric 100 of the tow ring part when towed on both sides of the four sides where the tow ring is formed. It is characterized in that the reinforcing piece 124 is formed so that the tensile force is reinforced by stitching with Teflon yarn.

Furthermore, the size of the suffocating cloth 100 composed of inorganic fiber fabrics formed of the basalt fiber is expanded by connecting a plurality of suffocating cloths, and the ends facing each other between the suffocating cloths serving as the connecting portion are folded in “⊂” and “⊃” shapes. The folds 130 and 130' are formed so as to be cross-linked, and the Teflon cloth 140 is added to the inside of the crossed fold at least one place, and is sewn with Teflon yarn to be airtightly fixed. to be characterized

In addition, it is preferable that the rim of the suffocation cloth 100 is formed by forming an unwinding stitch 150 to prevent unraveling of the fibers of the rim of the suffocation cloth 100, and spring steel that is easily elastically deformed along the rim of the suffocation cloth 100. Or, when one of the shape memory alloys is rolled and sewn to extinguish a fire, the suffocation cloth rim is in close contact with the ground in a state where the suffocation cloth is covered on the fire source, and airtight means 160 is further formed to block the inflow of external air into the fire source. to be

The present invention forms a ceramic coating layer and an oxygen barrier layer on a fire-resistant woven fabric made of basalt fiber, and directly puts it into a fire source for special fires such as vehicle fires and oil fires, thereby blocking contact between the fire source and external air, thereby preventing harmful effects. It is possible to secure the safety of firefighters in the process of extinguishing a fire by suppressing gas generation and limiting emission, and minimizing firefighters' access to the fire source through towing means. has the effect of enabling rapid extinguishment of fire through perfect blocking of

In addition, the present invention can minimize economic loss due to fire by preventing the fire from spreading to surrounding facilities due to a special fire, preventing environmental pollution caused by spraying conventional fire extinguishing fluid, and cleaning up contaminated surroundings due to fire extinguishing fluid It has the advantage of preventing unnecessary input of manpower.

Hereinafter, technical features according to an embodiment of the suffocating cloth for fire suppression according to the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is a view showing the laminated structure of the suffocating cloth for fire suppression according to the present invention, Figure 2 is a view expressing the overall appearance of the suffocating cloth for fire suppression according to the present invention, Figure 3 is a view showing the fire suppression according to the present invention Figure 4 is a cross-sectional view showing the connection relationship for expansion of the suffocating cloth for fire suppression according to the present invention, and Figure 5 is a suffocating cloth for fire suppression according to the present invention. It is a side view showing a state of use, and FIG. 6 is a view showing another embodiment of a suffocating cloth for fire suppression according to the present invention.

The suffocating cloth for fire suppression according to the present invention is a fire extinguishing blanket for extinguishing use in which fire extinguishing powder or extinguishing fluid is directly thrown into a flame in a form containing extinguishing powder or extinguishing fluid so that the extinguishing powder or extinguishing fluid comes into contact with the flame. There is a problem that the fire must be extinguished again because there is residual fire, and if it is missed, there is a problem that leads to a fire again, and there is also a problem that the fire spreads to the surroundings. In addition, most of the existing fire extinguishing blankets or fire blankets were simply used for the purpose of protecting evacuees from flames or used for firefighters' protective clothing, etc. There is a problem that acts as a raw material source for further development.

Therefore, the present invention covers the entire fire source rather than inserting it directly into the fire source by embedding the extinguishing powder or extinguishing fluid, and it is possible to suppress even the fundamental cause of the flame through complete blocking from the air, eliminating the need for a separate waste work, and the fire suppression process It is not necessary to worry about the safety of firefighters according to the patent, and it is configured to meet the recent fire trend.

Recently, the aspect of fire is changing due to the explosive increase of automobiles and the appearance of electric vehicles, and a configuration capable of suppressing fire through quick response is required. In the case of a car, the fire spreads rapidly at a considerable temperature, and there is a risk of explosion due to the presence of an oil storage tank. Moreover, when a fire develops rapidly, it is easy to propagate by oil to the surroundings, so rapid extinguishing is required. Moreover, there is a problem that the fire will start again even after the first suppression due to the internal residual fire according to the structure of the car, so it is necessary to fundamentally block it to extinguish the fire, and in the case of electric vehicles, there is a risk of electricity discharge. Firefighters are limited in their ability to approach and extinguish the fire. Rather, firefighters may be exposed to electricity in the process of extinguishing a fire, which may cause casualties, so a configuration capable of suppressing it more dramatically is required.

With respect to such recent fire aspects, it can be achieved through the present invention to enable immediate response to special fires such as automobile fires or oil fires, where the space of the fire source is small but the damage caused by the fire can be large.

That is, as described above, the suffocation cloth of the present invention is configured to be applicable to a fire source such as a car fire or an oil fire in which the fire is small in scale but the damage of the fire may be large, as shown in FIG. It is configured to extinguish the fire by blocking it from the outside air. Since conventional firefighting blankets or fireproof blankets are only used for simple blocking of fire sources, and practically fire suppression is impossible, the above-mentioned problem can be easily solved through the fire suppression suffocation cloth according to the present invention.

To this end, the suffocating fabric for fire suppression according to the present invention is made of basalt fiber, which has excellent incombustibility and is not harmful to the human body while completely blocking the outside air. The suffocation cloth 100 formed of inorganic fiber fabric for fire suppression is formed so that it can be formed in any one of polygonal shapes.

Here, the twill weave is one of the three-way structure of the fabric along with the plain weave and the satin weave, and is also called a serpentine weave because it has a ridge pattern in the cross direction. Various patterns can be made according to the difference in how the thread is interlocked, but the simplest structure is the Sammaereung (三枚綾). In addition, according to the difference in the shape of the four patterns, it is roughly divided into regular four patterns and change four patterns. . The direction and angle of the ridge lines formed on the surface of this fabric differ depending on the density, texture, and twist direction of the threads constituting the fabric. For example, the ridge of a serge passes from the lower left to the upper right on the outer surface of the fabric, and the angle is usually 45°. The fabric woven with this twill weave is a twill weave, which is generally relatively dense and tough, and has characteristics such as high gloss when the ups and downs are long. There are very many types, and representative ones include suiting and overji such as serge, gabardine, and herringbone, which are woolen, and work welfare, such as taerung and sereung, which are cotton. It is described as [Naver Encyclopedia] Twill weave [twill weave, 綾織] (Doosan Encyclopedia).

That is, as the basalt fiber according to the present invention is twill weaved to form an incombustible suffocating cloth, as shown in FIGS. 2 and 3, firefighters are disposed on the left and right to pull the suffocating cloth to the fire As it matches the 45° angle of the twill weave with respect to the direction of the diagonal tensile force, problems such as tearing or scratching of the suffocating cloth during the pulling process can be minimized.

On the other hand, as shown in FIG. 1, basalt fiber has a high temperature resistance that can withstand up to about 1500 ° C., has excellent mechanical properties, generates little dust in the combustion process, and is an eco-friendly material that is harmless to the human body and is non-flammable. am. As these basalt fibers are made into twill weave, they can be used as suffocation fabrics. However, in consideration of the difficulty of extinguishing fire due to the inflow of outside air into the voids between the fibers, a ceramic flame retardant coating solution is applied to the suffocation fabrics twilled with basalt fibers. By filling the gap, when the fire source is covered with suffocation cloth, it is configured to prevent contact with the outside air and to enable fire suppression.

Here, the ceramic flame retardant coating solution is flame retardant coated on the upper and lower surfaces of the suffocating cloth 100 formed of the inorganic fiber fabric for fire suppression twilled with basalt fiber, and contains 0.8% by weight of magnesium oxide based on 100.0% by weight of the ceramic flame retardant coating solution. , 27.2% by weight of silicon oxide, 6.0% by weight of an amino alkyd resin to prevent cracks and improve flame retardancy of ceramics as a binder, 17.0% by weight of ceramic to which a fiber penetrating agent was added, and 49.0% by weight of water A flame retardant coating layer formed by coating a ceramic flame retardant coating solution. (110).

The magnesium oxide is used as a raw material for high-temperature furnace materials, crucibles, and refractory cement, and has a melting point of 2,800° C., so it is possible to increase the heat resistance of suffocating cloth twilled with basalt fibers.

The silicon oxide is also referred to as silica, and exists as a solid at room temperature with a melting point of 1,600 ° C.

The amino alkyd resin is a synthetic resin for paint made by mixing an amino resin and an alkyd resin. Here, the amino resin hardens by causing an addition condensation reaction by the action of heat or acid, and when used as a paint, the coating film is hard, but it is easily crumbly and has little adhesion. When an alkyd resin is mixed with this, the carboxyl group and hydroxyl group in the alkyd resin accelerate the curing of the amino resin and participate in the hybrid condensation reaction, so that the resulting coating film is hard but does not come off easily, and has excellent adhesion, water resistance, alkali resistance, Complementary color is excellent.

The amino alkyd resin with such characteristics can prevent cracks and improve flame retardancy of the ceramic as described below on the asphyxiating cloth twilled with basalt fiber while serving as a binder, and attach to the upper and lower surfaces of the asphyxiating cloth of magnesium oxide and silicon oxide described above improve sexuality

Here, the amino alkyd resin is obtained by polymerization of an acrylic and an ethylene-vinyl acetate copolymer (EVA), and is formed through an amino resin-based acrylic and an alkyd resin-based ethylene-vinyl acetate copolymer, It is possible to produce an eco-friendly suffocation cloth that is more harmless to the human body.

The ceramic is mainly used for ceramics, but it is an important material in the industrial sector today and has advantages such as heat resistance, high strength, and corrosion resistance, so it is also added to improve the heat resistance, strength and corrosion resistance of the suffocating cloth.

The fiber penetrating agent is injected so that the ceramic, magnesium oxide, silicon oxide, etc. can easily penetrate between the twill weave of basalt fibers, and the fiber penetrating agent is added to 17.0% by weight of the ceramic, 9.0% by weight of the ceramic, and the fiber penetrating agent. It is prepared with 8.0% by weight of at least one selected from the group consisting of nonionic surfactants, benzene, carbon tetrachloride, n-tetradecane, and isopropyl alcohol.

On the other hand, the ceramic flame retardant coating aqueous solution is applied to the upper and lower surfaces of the twill weave asphyxia cloth 100 with basalt fibers to form the flame retardant coating layer 110. After applying the aqueous solution, drying to form a flame retardant coating layer on the upper and lower surfaces of the suffocation cloth, it is formed to 0.4 ± 0.05 mm through a compression step by a press. Here, if the thickness of the suffocation cloth on which the flame retardant coating layer is formed is less than 0.35 mm, the tensile force and durability deteriorate, resulting in scratches on the surface of the suffocation cloth during the traction process, resulting in local damage and the formation of voids, resulting in the ability to block external air. this may deteriorate. On the other hand, if it is formed larger than 0.45 mm, the total weight of the suffocation cloth increases, so the manpower of firefighters towing to the fire source must be supplemented, and the towing speed and ability may be significantly reduced, and it is difficult to maintain airtightness with the ground due to poor ductility. Blocking is difficult.

In this way, a fabric in which a flame retardant coating layer is formed on the upper and lower surfaces of the basalt fiber twilled asphyxia fabric is used in a flower garden in a shape of any one of a square, a circle, and a polygon. As shown in FIG. 2, the suffocation cloth 100 composed of the inorganic fiber fabric formed of the basalt fiber produced in this way is formed in a square shape because it is generally rectangular, and the four-sided suffocation cloth on the plane of the square suffocation cloth To the traction means 120 is formed.

As shown in FIGS. 2 and 3, the towing means 120 is sewn with Teflon yarn to keep the tow hook 122 airtight in the four suffocating cloths, and towed to both sides of the four chambers where the tow hooks are formed. The tensile reinforcement piece 124 twilled with basalt fiber is sewn with Teflon yarn to prevent damage due to the tensile force caused by the traction of the suffocating cloth 100 in the tow ring portion, so that the tensile force is reinforced. Here, the tow hook 122 may be configured in a ring shape, but may be configured in a metallic ring shape such as an eye ring. However, when perforating the suffocating cloth in four directions to form a metallic ring shape, it is preferable to form the suffocating cloth on the inside of the eye-ring to be in close contact with the ground so that the inflow of external air can be blocked through the perforated inner edge.

On the other hand, the backstitch with the Teflon thread is to prevent the formation of voids in the backstitch area due to the backstitch, and the airtightness of the backstitch portion can be maintained by the expansive force of the Teflon thread. That is, when stitching for fixing the traction means, airtightness of the stitched part can be maintained through the Teflon thread, so that the sealing force of the suffocating cloth can be improved.

Furthermore, if the size of the fire source that caused the fire is large, for example, in case of a car fire, the size of the suffocation cloth should be expanded to cover the entire car, depending on the size of the car. should be provided according to the size of At this time, in order to increase the size of the suffocation cloth, a plurality of suffocation cloths 100 composed of inorganic fiber fabrics formed of the basalt fiber are connected to expand the size, and to configure the expansion, the suffocation cloth 100 is connected to each other As shown in FIG. 4 , the end side facing the suffocation cloth serving as the connecting portion is folded and overlapped in the shape of “⊂” and “⊃”, and the folded portions 130 and 130' are formed so as to be cross-connected. In addition, it is configured by adding at least one place on the inside where the Teflon cloth 140 is crossed to the inside of the crossed folds, and is sewn with Teflon yarn to be airtightly fixed.

Here, the Teflon cloth 140 is configured to block the inflow of external air by filling the gap in the folded portion. That is, when air gaps are generated due to the overlapping of suffocating cloths in the folded part, air can be easily introduced from both ends of the folded part, and when it is configured in the form of an air bag and comes into contact with a fire source, the folded part due to the expansion of air This is to solve the difficulty of extinguishing the fire due to the inflow of outside air due to the problem that the stitching part may open. As described above, the stitching with the Teflon thread is to block the inflow of outside air into the stitching part.

On the other hand, when the suffocating cloth 100 covers the car in case of a car fire to block the outside air and the fire source, the rim of the suffocating cloth should be formed so as not to spread in close contact with the ground, and due to external environmental factors It is necessary to prevent loss of adhesion. In addition, in order to solve the problem that the adhesion efficiency with the ground is reduced due to the problem of the fibers of the rim of the suffocating cloth being released, the rim of the suffocating cloth 100, as shown in FIGS. It is preferable to form a suffocation cloth edge to prevent fiber loosening, and to use Teflon yarn even during the unwinding stitch 150 to maintain airtightness.

In addition, as shown in FIG. 6 so that the rim of the suffocation cloth can increase adhesion with the ground, any one of spring steel or shape memory alloy, which is easily elastically deformed along the rim of the suffocation cloth 100, is a rolled sewing When extinguishing a fire, it is preferable that an airtight means 160 is further formed so that the rim of the suffocation cloth is in close contact with the ground in a state where the fire source is covered with the suffocation cloth to block external air from entering the fire source.

That is, when the airtight means 160 is not formed, it is configured to block the inflow of external air by folding between the ground and the fire source of the car fire in case of a car fire with the flexible flexibility of the suffocating cloth, but to form the airtight means When the airtight means acts as a weight, it is in close contact with the ground and the outside air is blocked, so that fire suppression can be easily performed. However, it is not preferable to form the airtight means 160 on the entire rim. In the case of uneven ground, there is a problem that the outside air flows into the fire source due to the uneven ground or road surface in the part that acts as a weight, and the ground and suffocation by airtight means in the process of operating the suffocation cloth It is preferable to form a partial airtight means because dragging occurs in a state in which a load is applied between the bundles, which can cause breakage or damage to the suffocation cloth.

As shown in FIG. 1, the fire suppression suffocation fabric 100 according to the present invention having such a configuration is formed with a flame retardant coating layer 110 to improve heat resistance, as shown in FIG. 2, in four rooms. After configuring to form a towing means, it can be folded and stored in a minimum volume when a fire does not occur.

Then, when a fire occurs, considering the characteristics of the fire, for example, it is not suitable for a fire in a general house or building, but is used in a special fire such as a car fire. Accordingly, when a car fire occurs, firefighters are dispatched to the scene, after estimating the size of the car, selecting an appropriate size suffocation cloth, 2) As shown in FIG. 2, two firefighters become a team and spread the suffocation cloth while moving together in a state as far away from the car fire as possible by hanging a heat-resistant rope or string on the towing hook.

Here, the traction means has a structure that can withstand the suffocation cloth sufficiently even if it moves while pulling the traction hook by the traction line as the tension reinforcement piece is formed vertically, and as shown in FIGS. 2 and 3, the twill weave It has durability that can strongly withstand the pulling force with the towline from the front of the suffocation cloth in the diagonal direction by the weaving direction at a 45° angle.

Then, after quickly covering the suffocating cloth coupled to the towing hook of the traction means with a towline in a state far from the car fire with the car fire part, as shown in FIG. 5, the suffocating cloth is in close contact with the ground or the road surface After folding it to cover the entire car on fire by the suffocating cloth, the fire is extinguished. The fire suppression evolves quickly by blocking the air, but if the suffocating cloth is opened immediately in a short time, there is a problem that it will be re-ignited by the internal heat source. It is desirable to do However, if the cooling rate by the suffocation cloth is slow, it can be additionally applied to the outside of the suffocation cloth as a fire extinguishing agent that can minimize contamination such as water.

After that, when the fire is completely extinguished, the suffocation cloth is folded and stored again, so that it can be used continuously. That is, by using the suffocating cloth, water cannot be used, such as car fires or oil fires, and difficulties in extinguishing fires due to environmental pollution or explosions that may occur due to the use of special fire extinguishing fluids can be more effectively and quickly extinguished. It is possible to minimize the risk of fire expansion in which the fire can spread to surrounding facilities or vehicles, and to minimize the generation of a large amount of toxic gas in the event of a fire.

In the above, the present invention has been described in detail as one embodiment, but the scope of the present invention is not limited thereto, and it is clear that many variations and modifications are possible to those skilled in the art within the scope of the technical idea, and the present invention It will be said that it is included up to the embodiment and substantially equivalent scope. Technical features will be described in detail.
