Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of traffic safety and emergency protection equipment, and particularly relates to a wearable fireproof product capable of being converted into various pillow forms by orderly folding itself, and a manufacturing method and system thereof, which is particularly suitable for various vehicle seat environments. BACKGROUND

[0002] In the prior art, there is a scheme of storing a fireproof blanket as a pillow. This scheme has significant defects: first, the fireproof blanket is essentially a barrier, not a wearable product, and cannot provide convenient full-body protection in an emergency. Second, its conversion target is single (usually only a pillow), and it fails to fully utilize other parts of the seat to achieve functional integration. In addition, if a piece of fireproof cloak or fireproof clothing is simply crumpled and stuffed into a pillowcase bag, an unevenly filled, shape-unfixed, bulky pillow will be formed, which is extremely uncomfortable. More importantly, in an emergency, it is extremely difficult to quickly take out and unfold the wearable product from a tangled piece of fabric, which can easily delay valuable escape time and fail to meet the basic requirements of emergency protection products. Further, even the existing technologies that propose the concept of "wearable fireproof product convertible into a pillow" generally have problems such as reliance on user skills during conversion, insufficient stability of the converted form, and the need to improve the overall thermal protection efficiency. In addition, the inner layer of the fireproof product in the prior art usually only considers flame retardance and air permeability. However, in specific disasters such as new energy vehicle battery fires, electrolyte with strong corrosive properties may be leaked. The protective performance of the inner layer material of the traditional fireproof clothing will rapidly deteriorate or even dissolve upon contact with such electrolyte, resulting in a loss of protection ability and causing secondary chemical damage to the user. This is a blind spot that the prior art has not recognized and solved. The present application aims to fundamentally solve these technical problems. SUMMARY

[0003] The technical problem to be solved by the present application is to overcome the deficiencies of the prior art and provide a wearable fireproof product convertible into a pillow by means of built-in folding guide structure and orderly folding reconstruction to realize functional conversion, which solves the problems of the prior art that protection and comfort cannot be balanced, the storage form is single, it is inconvenient to take out, the conversion reliability is poor, and there is a lack of chemical corrosion resistance. To solve the above technical problems, the present application adopts the following technical solutions: (1) A wearable fireproof product capable of being folded into a pillow, characterized in that it comprises: a flexible fireproof body configured to be worn on the human body to provide fire protection; wherein the interior or surface of the flexible fireproof body is provided with a folding guide structure for guiding and fixing the folding path; the flexible fireproof body can be reconfigured into a self-supporting pillow component through a series of ordered folding operations guided by the folding guide structure; the pillow component is adapted to the vehicle seat environment and includes at least one of a neck pillow, a waist pillow, a throw pillow, and a backrest; the pillow component has self-supporting properties and can maintain its predetermined shape without external constraints, and can be used independently as a pillow; (2) The flexible fireproof body is composed of a composite flame-retardant material, including a weather-resistant outer layer, a nano-porous heat-insulating layer, and a flame-retardant chemical-resistant inner layer arranged in sequence; optionally, a heat-reflecting layer is provided in the composite structure to reflect radiant heat in a fire environment, further improving the overall heat-insulating effect. The flame-retardant chemical-resistant inner layer includes a microporous polymer film resistant to electrolyte corrosion, which can effectively resist the corrosion of battery electrolyte, maintain its structural integrity and protective performance, and provide dual protection of fire and chemical corrosion for the user.

[0004] The beneficial effects of the present application are: (1) One thing, two uses, space efficient and stable shape: through the built-in folding guide structure and ordered folding to reconfigure into a self-supporting pillow component, fundamentally different from the "simple insertion" solution, combining daily comfort and emergency protection, with high compression rate (≥50%), greatly saving vehicle space; (2) Convenient to use, fast response, high reliability: the folding guide structure makes the operation streamlined and standardized, so that users can complete most of the folding steps by feel even without referring to the instruction manual, overcoming the fatal flaw of difficult access. The pillow shape is stable and can be quickly deployed and worn, saving valuable time for escape; (3) Comprehensive protection, high efficiency and chemical resistance: through the composite flame-retardant material layer, especially using inorganic aerogel with a normal temperature thermal conductivity coefficient ≤0.020 W / (m·K) as the heat-insulating layer, the product is light and thin while achieving high-efficiency heat insulation. Through the optional heat-reflecting layer, the protection against radiant heat is further improved. Most importantly, by setting the flame-retardant chemical-resistant inner layer resistant to electrolyte corrosion, the industry problem of traditional fireproof clothing being easily corroded by electrolyte in battery fire is solved, providing comprehensive safety protection; (4) Clear and distinct protection range: taking "wearable fireproof product + folding guide structure + self-supporting pillow component" as the core and expanding to the unique composite fabric structure, a clear and solid patent protection range is constructed, covering products, manufacturing methods and systems, and effectively distinguishing from existing technologies.

[0011] Example 1: The wearable fireproof product is a fireproof cloak. Its flexible fireproof body adopts a composite layered structure: the outer layer is basalt cloth with a thickness of about 1mm; the middle layer is pre-oxidized fiber aerogel felt with a thickness of about 1mm; the inner layer is a flame-retardant and chemical-resistant inner layer formed by thermal bonding of a microporous polymer membrane resistant to electrolyte corrosion and an aramid non-woven fabric with a density of 200g / m². Its surface is provided with a folding guide structure, which folds it into a rectangular pillow component through an orderly winding folding method. Figure 3 The pillow component has a stable structure and can stand upright on its own (self-supporting), with a volume compression rate of 65%. The electrolyte-resistant microporous polymer membrane can be made from a wide range of materials, including but not limited to: fluoropolymer membranes such as polyvinylidene fluoride (PVDF) and polytetrafluoroethylene (PTFE); ethylene-vinyl alcohol copolymer (EVOH) membranes; polyphenylene sulfide (PPS) membranes; or thermoplastic polyurethane (TPU) membranes. Experimental verification has shown that some of the above materials (such as PVDF and PPS) exhibit excellent chemical stability after immersion in common lithium-ion battery electrolytes for 24 hours, retaining ≥90% of their tensile strength without swelling or dissolution, fully meeting the requirements for chemical protection in battery fires. As a preferred reinforcement, an aluminum-plated film is laminated between the intermediate layer (pre-oxygenated fiber aerogel felt) and the outer layer to form a heat-reflective layer. This layer effectively reflects radiant heat in a fire, synergizing with the insulation effect of the aerogel to further enhance protection against instantaneous thermal shock.

[0012] Example 2: In another embodiment, the outer fabric of the wearable fireproof product uses aramid fabric with both flame retardant and aesthetic properties. By being folded in order to become a square, the square pillow component can be placed in a square pillow cover with aesthetic appearance, becoming a throw pillow. Figure 4 ).

[0013] Example 3: In this embodiment, the structure of the composite flame-retardant material is: outer layer (high-silicon-oxygen cloth), heat reflection layer (aluminum plating layer), nano-porous heat insulation layer (aerogel), and flame-retardant chemical-resistant inner layer (PVDF composite aramid). This structure is particularly suitable for environments with high-intensity radiation heat risks.

[0014] Example 4: In this embodiment, the hooded fireproof cloak is provided with a chemical oxygen self-generating miniature respirator at the collar (1 Figure 5 ), which has an elastic cord for convenient wearing. A special storage bag is provided inside the cloak for accommodating a chemical oxygen self-generating miniature respirator. The respirator is connected to a fire-fighting oxygen supplier through a high-temperature-resistant air guide tube. At the same time, the cap side of the cloak is provided with a transparent flame-retardant high-temperature-resistant face shield, and a visible face shield made of TPU flame-retardant transparent film is fixed on the side of the hood, which can be lifted and covered on the face, and is fixed on the other side of the hood (2 Figure 6 ).
