KR-20260063394-A - digestive phagosomes

Abstract

The present invention relates to a fire extinguishing cloth for electric vehicle fire suppression, and more specifically, to a fire extinguishing cloth for electric vehicle fire suppression that not only suppresses a fire by simply blocking external air, but also efficiently suppresses a fire by effectively blocking oxygen through a fire suppression substance embedded in a fire suppression material, when the temperature rises above a certain level, by causing microcapsules in a fire extinguishing film attached to the bottom of the fire extinguishing cloth to burst. 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. 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, 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.

Description

Digestive phagosomes for electric vehicle fire suppression The present invention relates to a fire extinguishing cloth for electric vehicle fire suppression. The present invention relates to a fire extinguishing cloth for electric vehicle fire suppression that not only suppresses a fire by simply blocking external air, but also efficiently suppresses a fire by allowing microcapsules in a fire extinguishing film attached to the bottom of the fire extinguishing cloth to burst when the temperature rises above a certain level, thereby enabling the fire suppressing substance embedded in the capsules to effectively block oxygen. 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. 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, 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. Recently, as the demand for portable electronic products such as laptops and mobile phones has increased rapidly and the development of energy storage batteries, robots, and satellites has accelerated, research on high-performance secondary batteries capable of repeated charging and discharging is underway. Currently commercialized rechargeable batteries include nickel-cadmium, nickel-hydrogen, nickel-zinc, and lithium-ion batteries. Among these, lithium-ion 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 rechargeable batteries, allowing for free charging and discharging. 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. Thus, the most critical component of hybrid or electric vehicles is the vehicle battery, which provides driving power to the vehicle motor. Meanwhile, one of the major social issues regarding batteries is the problem of battery safety. 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. 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. 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. Fires involving lithium-based electric vehicle batteries are becoming 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. 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 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 penetrates the second layer of the reinforcing part and the second layer of the fire extinguisher body simultaneously," but 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
