[0028] Embodiment one

[0029] Please refer to Figure 1 As shown in the drawings, the present application is a microcapsule fire extinguishing blanket, which comprises a blanket body 1. The material of the blanket body 1 includes but is not limited to one of glass fiber, ceramic fiber, high-silica fiber or polyimide fiber.

[0030] The surface of the blanket body 1 is covered with fire extinguishing microcapsules 3 and refrigeration microcapsules 4. The fire extinguishing microcapsules 3 and the refrigeration microcapsules 4 are bonded to the surface of the blanket body 1 by adhesive. The blanket body 1 of the fire extinguishing blanket has a fixing belt 2 which can be held and installed. The width of the fixing belt 2 should not be less than 20 mm, the length of the grippable part should be 150 mm to 200 mm, and the length of the part within the edge of the blanket surface should not be greater than 60 mm. The fire extinguishing blanket can be installed at a specific position by the fixing belt 2 to passively prevent early fire or actively cover fire extinguishing by hand holding.

[0031] The adhesive glue includes but is not limited to one of silicone glue, epoxy resin glue, polyurethane glue or acrylic glue. The fire extinguishing microcapsule 3 and the refrigeration microcapsule 4 are both of shell-core structure, and the total weight ratio of the fire extinguishing microcapsule 3 to the refrigeration microcapsule 4 is 5-10:1-5, such as 5:5 or 6:4. The fire extinguishing microcapsule 3 and the refrigeration microcapsule 4 are mixed according to the weight ratio, uniformly mixed, and then uniformly bonded on the surface of the blanket 1 by the adhesive glue.

[0032] As shown in Figure 2 , the fire extinguishing microcapsule shell 301 of the fire extinguishing microcapsule 3 is a synthetic polymer material, including but not limited to one of acrylate resin, urea-formaldehyde resin or polyurethane resin; the fire extinguishing microcapsule core material 302 of the fire extinguishing microcapsule 3 includes but is not limited to one of Novec1230, Novec7100, Novec7300 or heptafluoro-propane, which will not cause harm to the electrical cabinet equipment, or the fire extinguishing microcapsule 3 uses other types of fire extinguishing microcapsules in the prior art.

[0033] As shown in Figure 3 , the mass ratio of the refrigeration microcapsule shell 401 to the refrigeration microcapsule core material 402 of the refrigeration microcapsule 4 is 1:1-9, such as 2 or 1:3, etc. The refrigeration microcapsule shell 401 of the refrigeration microcapsule 4 is a synthetic polymer material, including but not limited to one of acrylate resin, urea-formaldehyde resin or polyurethane resin, and the refrigeration microcapsule core material 402 includes but is not limited to one of F500 aqueous solution, inorganic salt aqueous solution, pure water or seawater. Figure 1

[0034] The inorganic salt aqueous solution is one or more of potassium carbonate, potassium bicarbonate, sodium carbonate, sodium bicarbonate, potassium chloride or sodium chloride aqueous solution.

[0035] The sodium chloride solution or seawater is directly used as the refrigeration microcapsule core material 402 and as the internal phase solution. The refrigeration microcapsule shell 401 is used as the external phase solution and is prepared by using microfluidic technology to form microdroplets of the refrigeration microcapsule shell 401 wrapping the refrigeration microcapsule core material 402, so that the refrigeration microcapsule shell 401 is solidified to form the refrigeration microcapsule 4.

[0036] The fire extinguishing microcapsule 3 is broken by heat to spray out fire extinguishing agent to achieve chemical fire extinguishing, and the refrigeration microcapsule 4 is broken by heat to spray out the F500 aqueous solution, inorganic salt aqueous solution, pure water or seawater to form fine water mist to achieve physical cooling. The two work together to effectively improve the overall fire extinguishing effect, so that the fire is extinguished at the initial stage, and the fire blanket is used to cover the fire source to achieve physical oxygen isolation, thereby effectively improving the overall fire extinguishing efficiency.

[0037] ​At the same time, through the joint action can quickly reduce the space temperature for the relevant personnel to provide a safe post-processing environment, so that the fire blanket has stronger initiative and fire adaptability, effectively ensures the overall fire cooling reliability and the overall fire efficiency.

[0038] Embodiment two

[0039] Based on embodiment one, when the core material of the refrigeration microcapsule 4 is one of inorganic salt aqueous solution, pure water or seawater, the refrigeration microcapsule core material 402 is mixed with water-based surfactant, the water-based surfactant is sodium dodecyl sulfate or sodium dodecyl benzene sulfonate, and the concentration is 0.1% to 5%. The water-based surfactant reduces the tension of the aqueous solution, which is beneficial to wetting the surface of the object, thereby further improving the fire extinguishing effect.

[0040] The core material is mixed with an antifreeze agent, and the amount of the antifreeze agent added is inversely proportional to the concentration of the inorganic salt aqueous solution of the cold microcapsule core material 402. The inorganic salt aqueous solution is added with an antifreeze agent, so as to prevent the cold microcapsule core material 402 from solidifying in a low temperature environment, thereby further improving the adaptability of the fire extinguishing microcapsule to the use environment by adding the antifreeze agent.

[0041] And the amount of the antifreeze agent added is inversely proportional to the concentration of the inorganic salt aqueous solution of the cold microcapsule core material 402. Since the higher the concentration of the inorganic salt solution, the lower the freezing point of the inorganic salt solution, the amount of the antifreeze agent to be added can be correspondingly reduced, and the amount of the antifreeze agent can also be adjusted flexibly according to the use environment or no antifreeze agent can be added.
