Description

Novel microcapsule initiative fire blanket Technical Field The invention relates to the technical field of fire extinguishing devices, in particular to a novel microcapsule active fire blanket. Background The fire blanket is a nondestructive fire extinguishing tool, has the characteristics of being superior to other fire extinguishing tools, is simple, convenient and practical, and is particularly effective for extinguishing small-sized fires. Currently, fire-extinguishing blankets are quite popular in many countries or regions, and are fire-extinguishing initial fire-extinguishing tools equipped in families, shops, restaurants, hotels, entertainment venues, shops, office buildings, hospitals, gas stations, warehouses, automobiles, ships, airplanes, enterprises, civil buildings and other places, and the traditional fire-extinguishing blankets are mostly made of inorganic materials, and are used for covering fire sources through manual operation to realize physical oxygen isolation, so that the fire-extinguishing effect is achieved. The patent document with the publication number of CN221229856U discloses a fire blanket, which comprises a blanket body and hydrogel, wherein the hydrogel is arranged on the surface and/or the inside of the blanket body, and the thickness of the hydrogel is d, and d is more than or equal to 0.5mm and less than or equal to 3mm. Foretell fire blanket is through locating the hydrogel on the surface and/or the inside of the blanket body, and the thickness scope of hydrogel is 0.5mm to 3mm, when the condition of a fire takes place for the goods that the fire blanket covered, the hydrogel can absorb heat and flue gas, reduces the temperature in burning area, and the isolated oxygen, suppresses the burning to, the fire blanket can also form the effect of cut off, reduces the risk that the condition of a fire spread, but prior art still has the defect: Fire blanket among the prior art suppresses the condition of a fire through hydrogel absorption heat, but its absorption heat is limited, and initiative fire extinguishing effect is relatively poor, and holistic fire extinguishing efficiency is lower. The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art. Disclosure of Invention The invention aims to overcome the defects and provide a novel microcapsule active fire blanket. In order to solve the technical problems, the technical scheme provided by the invention is that the novel microcapsule active fire blanket comprises a blanket body and is characterized in that: The blanket body comprises a flame-retardant outer layer, a hydrogel heat storage layer and a microcapsule fire extinguishing layer which are sequentially stacked from outside to inside, wherein the microcapsule fire extinguishing layer is arranged on the inner side of the hydrogel heat storage layer, the microcapsule fire extinguishing layer is a porous fiber pad or a non-woven fabric layer, and a hydrophobic breathable film is further arranged on one side, facing a fire source, of the microcapsule fire extinguishing layer.
