Description

Technical Field

[0001] This invention relates to the field of fire extinguishing materials, and in particular to a multi-component gaseous fire extinguishing agent composition, a capsule-based flexible fire extinguishing patch, and a method for its preparation. Background Technology

[0002] In industrial production, commercial sites, and infrastructure, distribution cabinets, as core equipment of power distribution systems, play a crucial role in power control and distribution. However, due to issues such as high-load operation of electrical components, aging wiring, short circuits, poor contact, and overload, high temperatures can easily occur inside distribution cabinets, potentially leading to fires. The fire extinguishing systems or products equipped with these cabinets typically employ internally pressurized or externally pressurized designs. Their core structure includes components such as cylinders and valves. These systems rely on additional control systems to trigger the release of extinguishing agents, resulting in a large size, heavy weight, and complex operation, limiting their application in compact spaces or scenarios requiring high portability. Furthermore, fires involving lithium-ion battery electric vehicles are frequent, and extinguishing fires after the battery catches fire is difficult. Using fire blankets can achieve localized fire control, and fire blankets can effectively prevent the spread of flames from a burning vehicle to surrounding vehicles, buildings, and other combustibles, reducing the risk of chain fires. However, existing fire blanket products generally do not contain extinguishing agents and lack active fire extinguishing capabilities; their fire extinguishing effectiveness, based on the principle of oxygen isolation and covering, is relatively weak.

[0003] Gaseous fire extinguishing agents have significant advantages in extinguishing electrical fires and lithium battery fires. Due to increasingly stringent environmental regulations, the use of traditional fire extinguishing agents such as heptafluoropropane is restricted. High-boiling-point novel gaseous fire extinguishing agents such as perfluorohexanone and 2-BTP have gained widespread application due to their excellent fire extinguishing capabilities and outstanding environmental performance. Microencapsulation is an effective way to encapsulate these high-boiling-point gaseous fire extinguishing agents. Microencapsulation technology encapsulates the fire extinguishing agent in micron or nanometer-sized capsules, which are then processed into sheet-like materials to form microcapsule fire extinguishing patches. When the fire extinguishing patch is exposed to a fire source or high-temperature environment, the outer shell of the microcapsule ruptures rapidly, releasing the fire extinguishing agent, thus achieving a rapid and precise fire extinguishing effect. This technology has significant application advantages, but it also has certain limitations: due to the limited encapsulation volume of microcapsules, the amount of extinguishing agent that a single fire extinguishing patch can carry is small, making it difficult to meet the needs of application scenarios requiring large doses of extinguishing agent; the manufacturing process of fire extinguishing patches is complex, and the technical requirements for mass production are high; the small size of microcapsules results in a small amount of extinguishing agent released per burst, limiting the fire extinguishing capacity; the extinguishing component is singular, usually perfluorohexanone, which has a high boiling point, resulting in delayed release of the extinguishing agent and low fire extinguishing efficiency; commercially available microcapsule fire extinguishing patches are mostly rigid structures, making them difficult to bend, and therefore unsuitable for flexible products such as fire blankets. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a multi-component gaseous fire extinguishing agent composition, a capsule-based flexible fire extinguishing patch, and a preparation method thereof. This invention achieves adjustable patch thermal sensitivity and improves the patch's reaction speed through the optimized design of the capsule material and wall thickness, using a multi-component compound fire extinguishing agent. The size of the fire extinguishing patch and the ratio of the fire extinguishing agent can be flexibly adjusted according to the specific application environment, achieving precise and efficient fire suppression.

[0005] In a first aspect, the present invention provides a multi-component gaseous fire extinguishing agent composition, which is achieved by the following technical solution.

[0009] Light stabilizer: 0%-0.2%;

[0010] Polymerization inhibitor: 0.2%-1%;

[0011] Dehydrating agent: 0.2%-1%;

[0012] The chemical gas extinguishing agent comprises a main component and a compounding agent. The main component is 1,1,1,2,2,4,5,5,5-nonafluoro-4-(trifluoromethyl)-3-pentanone (perfluorohexanone), and the compounding agent is selected from one or more of 2-bromo-3,3,3-trifluoropropene (2-BTP), 1,1,1,4,4,4-hexafluoro-2-butene (HFO-1336), and 1,2,3,3,4,4,5,5-octafluorocyclopentene (8FE). The mass percentages of the main component and the compounding agent in the multi-component gas extinguishing agent composition are as follows: main component: 49.2-74.5%; compounding agent: 22.3-49.2%.

[0013] Furthermore, the oxygen scavenger is selected from one or more of diphenyl dimethyl phosphonate, trilauryl phosphonate, triisooctyl phosphonate, and tris(2,4-di-tert-butylphenyl) phosphite.

[0014] Furthermore, the light stabilizer is selected from one or more of 2-(2'-hydroxy-3'-tert-butyl-5'-methylphenyl)-benzotriazole, 2-(3'-tert-butyl-2'-hydroxy-5'-methylphenyl)-benzotriazole, and phenyl salicylate.

[0015] Furthermore, the polymerization inhibitor is selected from one or more of hydroquinone, 2,2,6,6-tetramethylpiperidinyl hindered amine, 2,6-di-tert-butyl-p-cresol, and bis(2,2,6,6-tetramethyl-4-piperidinyl) sebacate.

[0016] Furthermore, the dehydrating agent is selected from one or more of 1-butyl-3-methylimidazolium hexafluorophosphate, butyl propionate, and ethyl acetate.

[0017] Secondly, the present invention provides a method for preparing a multi-component gaseous fire extinguishing agent composition, which is achieved by the following technical solution.

[0018] A method for preparing the above-mentioned multi-component gaseous fire extinguishing agent composition includes the following steps:

[0019] a. Add the specified amount of scavenger to the main agent and stir until well mixed;

[0020] b. Add the specified amount of light stabilizer to the solution obtained in step a and stir until homogeneous;

[0021] c. Then add the specified amount of polymerization inhibitor to the solution obtained in step b and stir until homogeneous;

[0022] d. Add the specified amount of dehydrating agent to the solution obtained in step c, and stir until homogeneous;

[0023] e. Finally, add the compounding agent to the solution obtained in step d and stir until homogeneous to obtain a multi-component gaseous fire extinguishing agent composition.

[0024] Thirdly, the present invention provides a capsule-based flexible fire extinguishing patch, which is achieved by the following technical solution.

[0025] A capsule-based flexible fire extinguishing patch includes capsules and a flame-retardant patch. A plurality of capsules are adhered to the flame-retardant patch. Each capsule includes a wall material shell, which is filled with the aforementioned multi-component gaseous fire extinguishing agent composition. Both ends of the wall material shell are sealed with a sealing material.

[0026] Furthermore, the outer shell of the wall material is made of a heat-sensitive polymer thin-walled tube with a wall thickness of 0.1-0.2 mm and a diameter of 1-10 mm. The length of a single outer shell is the same as the width of the flame-retardant patch.

[0027] Furthermore, the heat-sensitive polymer thin-walled tube is made of one or more of the following: flame-retardant polypropylene (PP), polyethylene (PE), polyvinylidene fluoride (PVDF), silicone, latex, perfluoroethylene propylene copolymer (FEP), polytetrafluoroethylene (PTFE), polyvinyl chloride (PVC), ethylene vinyl acetate copolymer (EVA), and nylon (PA).

[0028] Furthermore, the flame-retardant patch is a fiberglass mesh patch; the sealing material is a flame-retardant adhesive, which is selected from one or more of epoxy resin flame-retardant adhesive, acrylic flame-retardant adhesive, and fluororesin flame-retardant adhesive.

[0029] This application has the following beneficial effects.

[0030] This invention relates to a fire extinguishing patch that loads a multi-component gaseous fire extinguishing agent into a cylindrical capsule, sealed with a flame-retardant adhesive. Each capsule contains a large amount of fire extinguishing agent. During application, it can be flexibly cut to size and applied to different locations according to usage requirements. In the event of a fire, the internal fire extinguishing agent vaporizes upon heating, causing pressure to rise and burst, releasing the agent for rapid fire suppression. This cylindrical capsule-based flexible fire extinguishing patch is characterized by its simple manufacturing process, large single-release fire extinguishing dose, high fire extinguishing efficiency, lightweight and softness, high flexibility, and wide applicability. It can effectively address solid, liquid, and gas fires and is suitable for small enclosed spaces, battery pack casings, and flexible fire blankets. The fire extinguishing agent ratio can be flexibly adjusted according to the specific needs of the application site, optimizing the release of the fire extinguishing agent to achieve precise and efficient fire suppression.

[0085] Comparative Example 1

[0086] The difference between this comparative example and Example 1 is that the gaseous extinguishing agent is perfluorohexanone, and the content of the extinguishing agent filled is 3.90g.

[0087] Comparative Example 2

[0088] This comparative example uses commercially available perfluorohexanone microcapsule fire extinguishing patches, with a perfluorohexanone content of approximately 12.60g.

[0089] Fire extinguishing experiments were conducted on the columnar capsule-based flexible fire extinguishing patch filled with multi-component gaseous fire extinguishing agent prepared in the above embodiments, the pure perfluorohexanone in the comparative example, and the commercial microcapsule fire extinguishing patch. The fire extinguishing patch was attached to the top of the sealed box.

[0090] Design a small-scale fire extinguishing experiment in a closed space (with an opening for air entry). The volume of the closed space is 0.01125 m³. 3(0.3m × 0.25m × 0.15m). The fuel pan is circular with a diameter of 90mm. The fuel used in the experiment is anhydrous ethanol and electrical wire. The fuel pan is placed in the center of the bottom of the enclosed space. For the ethanol fire extinguishing experiment, 20mL of anhydrous ethanol is placed in the fuel pan inside the enclosed space, ignited, and the hatch is closed immediately. For the electrical wire fire experiment, 5m lengths of different types of standard electrical wire are cut, ignited, and pre-burned for 120s before the hatch is closed. Each extinguishing experiment is repeated four times, and the extinguishing time is recorded.

[0091] The extinguishing effects of the fire extinguishing patches used in Examples 1-3 and Comparative Examples 1-2 on extinguishing ethanol fires are shown in the table below:

[0092] Table 1 Comparison of extinguishing effects of ethanol on fires

[0093]

[0094] As shown in Table 1, the fire extinguishing patches of Examples 1-3 and Comparative Examples 1 and 2 can all extinguish ethanol fires, with the fire extinguishing patches of Examples 1-3 exhibiting superior extinguishing effects. The fire extinguishing patches of Examples 1-3 and Comparative Example 1 contain the same mass of extinguishing agent. The fire extinguishing patches of Examples 1 and 3, containing 2-BTP, and the fire extinguishing patch of Example 2, containing HFO-1336, all showed excellent extinguishing effects. While the fire extinguishing patch of Comparative Example 1, containing perfluorohexanone, could also extinguish the fire, its extinguishing time was longer and its extinguishing efficiency was lower. The fire extinguishing patch of Comparative Example 2 had the highest mass of extinguishing agent, but its extinguishing effect was the worst. Microcapsules achieve their extinguishing effect by encapsulating the extinguishing agent and releasing it upon contact with the fire source. However, incomplete rupture of the microcapsules can lead to insufficient extinguishing effect. During the production process, poor manufacturing quality of the microcapsules or improper storage can also cause premature rupture, resulting in poor extinguishing agent performance.

[0095] The fire extinguishing effects of the fire extinguishing patches used in Examples 1-3 and Comparative Examples 1-2 on extinguishing RVVB standard white electrical wires are shown in the table below:

[0096] Table 2 Comparison of fire extinguishing effects of RVVB national standard white electric wire

[0097]

[0098] Table 2 shows that the fire extinguishing patches from Examples 1-3 and Comparative Example 1 can extinguish fires involving RVVB standard white electrical wires, while the fire extinguishing patch from Comparative Example 2 fails to extinguish the fire. The fire extinguishing agents in Examples 1-3 and Comparative Example 1 are of the same mass. The fire extinguishing patches from Examples 1 and 3, which contain 2-BTP, and the fire extinguishing patch from Example 2, which contains HFO-1336, all exhibit excellent fire extinguishing effects. While the fire extinguishing patch from Comparative Example 1, which contains perfluorohexanone, can also extinguish the fire, its extinguishing efficiency is low. The fire extinguishing patch in Comparative Example 2 cannot extinguish fires involving RVVB standard white electrical wires.

[0099] The extinguishing effects of the fire extinguishing patches used in Examples 1-3 and Comparative Examples 1-2 on extinguishing RVB standard red and black parallel lines are shown in the table below:

[0100] Table 3 Comparison of Extinguishing Effects of RVB Standard Red and Black Parallel Line Fires

[0101]

[0102] Table 3 shows that the fire extinguishing patches from Examples 1-3 and Comparative Example 1 can extinguish RVB standard red and black parallel line fires, while the fire extinguishing patch from Comparative Example 2 fails to extinguish the fire. The fire extinguishing agents in Examples 1-3 and Comparative Example 1 are of the same mass. The fire extinguishing patches from Examples 1 and 3, which contain 2-BTP, and the fire extinguishing patch from Example 2, which contains HFO-1336, all exhibit excellent fire extinguishing effects when extinguishing RVB standard red and black parallel line fires. The fire extinguishing patch from Comparative Example 1, which contains perfluorohexanone, has a lower fire extinguishing efficiency. The fire extinguishing patch in Comparative Example 2 cannot extinguish RVB standard red and black parallel line fires.

[0103] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
