[0002] The present invention comprises an upper flame-retardant mat, a lamination means provided on the upper surface, and a fire extinguishing film having microcapsules embedded in the main body that release a fire suppression substance when the temperature exceeds a certain level.

[0003] A lower flame-retardant mat with a plurality of holes perforated in the lower part of the above-mentioned fire extinguishing film is further provided,

[0004] The upper flame retardant mat, fire extinguishing film, and lower flame retardant mat are characterized by being fastened and secured through a flame retardant thread to form a seam. Background Technology

[0006] Recently, as the demand for portable electronic products such as laptops and mobile phones has increased rapidly and the development of energy storage capacitors, robots, and satellites has begun in earnest, research on high-performance secondary batteries capable of repeated charging and discharging is underway.

[0007] Currently commercialized secondary batteries include nickel-cadmium, nickel-hydrogen, nickel-zinc, and lithium secondary batteries. Among these, lithium secondary batteries are gaining attention for their advantages, such as high energy density, very low self-discharge rate, and virtually no memory effect compared to nickel-based secondary batteries.

[0008] Furthermore, as carbon energy is gradually depleting and concern for the environment grows, the world is focusing on the development of hybrid and electric vehicles.

[0009] Thus, the most critical component of hybrid or electric vehicles is the vehicle battery, which provides driving power to the vehicle motor.

[0010] Meanwhile, one of the major social issues regarding batteries is the problem of battery safety.

[0011] Ensuring battery safety is recognized as a critical issue, as battery explosions or fires can not only cause damage to the devices in which they are installed but also lead to additional fires.

[0012] In particular, medium-to-large batteries used in hybrid or electric vehicles require a higher level of safety than small batteries used in general portable electronic devices. This is because medium-to-large batteries generate high voltage, which can inherently produce a significant amount of heat.

[0013] Furthermore, in the case of vehicle batteries, a fire may occur if the battery pack operates excessively while exposed to high temperatures during the sweltering summer, or if a major impact is transmitted to the battery due to an accident such as a vehicle collision, causing the protection function to malfunction or resulting in an internal short circuit.

[0014] Fires involving lithium-based electric vehicle batteries have become a concern, as evidenced by a recent incident in an apartment complex where an electric vehicle battery exploded and completely destroyed vehicles in an underground parking lot. Given the significant loss of life and property damage that can result from such fires, rapid fire suppression is now essential.

[0015] Regarding patents for such fire suppression suffocating cloths for electric vehicles, there is Korean Patent Registration No. 10-2405417 concerning fire suppression suffocating cloths, and

[0016] This patent is composed of "a fire extinguisher body made of a non-combustible fabric, a sewing thread made of a metal having a higher melting point than the fire extinguisher body and restraining a plurality of fire extinguisher bodies in a joined state, a heat-resistant coating layer coated on one or more surfaces of the fire extinguisher body, a gripping part attached to the edge of the fire extinguisher body to allow a user to grip it and having a color different from the fire extinguisher body, and a reinforcing part made of the same material as the fire extinguisher body and interposed between the gripping part and the fire extinguisher body, wherein the gripping part is restrained by the sewing thread to be integrated with the reinforcing part and the fire extinguisher body, and the ends of the reinforcing part and the fire extinguisher body are joined by the sewing thread in a state where they are rolled inward, so that the sewing thread simultaneously penetrates the second layer of the reinforcing part and the second layer of the fire extinguisher body," but

[0017] This patent has the problem that it is not suitable for fire suppression because the manufacturing cost is high and it is heavy due to the use of a metal heat-resistant coating layer, and the suppression effect is poor since it suppresses fire simply by blocking external air. The problem to be solved

[0019] The objective of the present invention is not only to suppress a fire by simply blocking external air, but also to enable the fire suppression substance embedded in the capsule to effectively block oxygen when microcapsules burst from the fire extinguishing film attached to the lower part of the fire extinguishing cloth.

[0020] Another objective of the present invention is to provide a fire extinguishing cloth for electric vehicles that can reduce the volume of the extinguishing cloth and facilitate movement by configuring the extinguishing film to be lightweight. means of solving the problem

[0022] The present invention, for achieving the above-mentioned purpose, comprises an upper flame-retardant mat and a fire extinguishing film having a lamination means on the upper surface and a main body containing microcapsules that release a fire suppression substance when the temperature exceeds a certain level.

[0024] In addition, a fire extinguishing cloth according to another embodiment of the present invention is further provided with a lower flame retardant mat having a plurality of holes perforated in the lower part of the fire extinguishing film, wherein the upper flame retardant mat, the fire extinguishing film, and the lower flame retardant mat are fastened and secured through a flame retardant thread to form a seam.

[0026] In addition, according to another embodiment of the present invention, the extinguishing suffocation cloth, which is composed of an upper flame-retardant mat and a flame-retardant film provided below the flame-retardant mat, is contained in a pocket of a flame-retardant material of a size corresponding to the extinguishing suffocation cloth having a hole perforated in the lower part, and is characterized in that the extinguishing suffocation cloth and the pocket are fastened and secured by penetrating with a flame-retardant thread to form a seam.

[0028] In addition, according to another embodiment of the present invention, a extinguishing film patch is laminated to the seam of the extinguishing sack to block the inflow of air. Effects of the invention

[0030] According to the present invention, not only is a fire suppressed by simply blocking external air, but when the temperature rises above a certain level, microcapsules burst from the fire extinguishing film attached to the lower part of the fire extinguishing cloth, and the fire suppressing substance embedded in the capsules effectively blocks oxygen, thereby efficiently suppressing the fire.

[0031] In addition, the present invention can reduce the volume of the extinguishing suffocation cloth by providing a configuration that simplifies the combination of the suffocation cloth and the extinguishing film while simultaneously doubling the binding force, and can facilitate movement by making the extinguishing film lightweight.

Specific details for implementing the invention

[0034] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings. The following detailed description is merely illustrative and illustrates a preferred embodiment of the present invention.

[0036] The fire extinguishing suffocation cloth (100) according to the present invention operates on the principle of extinguishing a fire by cutting off the oxygen supply when a fire occurs. Since electric vehicle battery fires can easily spread when they come into contact with oxygen due to the characteristics of lithium-ion batteries, the suffocation cloth that cuts off the oxygen supply is a very effective method.

[0037] Fire extinguishing suffocation blankets can prevent significant damage by blocking oxygen and preventing the spread of fire through rapid application in the early stages of a fire. Additionally, fire extinguishing suffocation blankets are highly effective in minimizing the generation of toxic gases that may occur during the fire suppression process, and electric vehicle fire extinguishing suffocation blankets are highly effective response equipment designed with the characteristics of battery fires in mind.

[0038] Figure 1 is a diagram showing the usage state of a fire extinguishing suffocation blanket for fire suppression in the event of an electric vehicle fire, and

[0039] As shown in FIGS. 2a and 2b, the present invention comprises an upper flame-retardant mat (10), an adhesive (22) on the upper surface, and a fire extinguishing film (20) with a microcapsule (24) embedded in the main body that releases a fire suppression substance when the temperature exceeds a certain level.
