Description

Technical Field

[0001] The present invention relates to the technical field of bullet-proof plate packaging, and in particular to a bullet-proof plate packaging method and the bullet-proof plate. Background Art

[0002] Airtight materials, with their dense structure, low permeability, and chemical stability, play a key role in building sealing, medical packaging, and electronic equipment protection. Their core function is to effectively block gas permeation. As a core component of protective equipment, bulletproof inserts must withstand extreme physical loads such as ballistic impact and knife penetration, while maintaining stable performance in harsh environments such as temperatures ranging from -40°C to 80°C, high humidity salt spray, sand and dust erosion, and underwater pressure. They must also meet the rigorous verification of protective effectiveness against multi-angle shooting and after environmental pretreatment, as required by standards such as NIJ0101.06 and MIL-STD-662F. Material aging and interfacial corrosion caused by long-term temperature and humidity fluctuations are the primary causes of protective performance degradation.

[0003] Existing packaging technologies for bulletproof inserts have significant limitations. Mainstream packaging methods include: encapsulation with ultra-high molecular weight polyethylene non-woven fabric. While this sewn structure provides basic cut resistance, the gaps in its weave easily form channels for water vapor penetration, making it difficult to meet the sealing requirements for high-temperature and high-humidity environments and the full waterproofing requirements for underwater combat. The complex processing also leads to increased costs. Encapsulation with polyurea coatings. While this coating process improves surface waterproofing, the increased weight caused by the high-density coating conflicts with the need for lightweight bulletproof inserts. Furthermore, the rigid coating is prone to cracking under impact, causing secondary leakage. More importantly, neither method effectively combines airtightness with mechanical damage resistance. Traditional airtight materials (such as polymer films), while offering excellent barrier properties, are easily damaged and fail due to their weak puncture resistance. High-strength fiber materials, while improving damage resistance, sacrifice sealing stability due to their open structure. This split in material properties makes it difficult for the existing packaging layer to maintain long-term protective effectiveness under complex stress coupling. It is urgent to develop new composite packaging methods to achieve synergistic optimization of airtight durability and dynamic damage resistance. Summary of the Invention

[0011] A further technical solution is that the specific operations of step S2 include:

[0012] According to the structure of "first-size composite structure airtight layer - bulletproof insert - second-size composite structure airtight layer", the bulletproof insert is placed between the first-size composite structure airtight layer and the second-size composite structure airtight layer, and the first-size composite structure airtight layer and the second-size composite structure airtight layer are pressed and sealed based on the reserved amount of the second-size composite structure airtight layer.

[0013] The remaining amount of the airtight layer of the composite structure of the first size after edge sealing is coated with adhesive and folded to the surface of the airtight layer of the composite structure of the second size, pressed and cured to complete the wrapping.

[0014] A further technical solution is that the edge sealing is performed by high-temperature pressing at a temperature of 110-120°C.

[0015] A further technical solution is that in step S3, the Oxford cloth has two sizes, namely a first-size Oxford cloth and a second-size Oxford cloth; a single side of the first-size Oxford cloth is 2 to 4 cm larger than a single side of the second-size Oxford cloth, and a single side of the second-size Oxford cloth is 2 to 4 cm larger than a single side of the bulletproof insert.

[0016] A further technical solution is that the specific operations of step S3 include:

[0017] According to the structure of "first-size Oxford cloth - bullet-proof insert wrapped around the composite structure airtight layer - second-size Oxford cloth", the bullet-proof insert wrapped around the composite structure airtight layer is placed between the first-size Oxford cloth and the second-size Oxford cloth, and the first-size Oxford cloth and the second-size Oxford cloth are sewn and sealed based on the reserved amount of the second-size Oxford cloth;

[0018] Apply adhesive to the remaining amount of the first-size Oxford cloth after edge sealing, fold it over to the surface of the second-size Oxford cloth, press and solidify, and complete the wrapping.

[0019] A further technical solution is that the material of the outer airtight film is selected from at least one of PE anti-seepage film, aluminum foil film, PVC film, and PET film.

[0026] Compared with the prior art, the embodiments of the present invention can achieve the following technical effects:

[0027] The present invention provides a method for packaging a bulletproof plate, comprising the steps of preparing a composite airtight layer: laminating an outer airtight film, a fiber fabric adhesive material, and an inner airtight film in a structure of outer airtight film-fiber fabric adhesive material-inner airtight film; completely wrapping the composite airtight layer around the surface of the bulletproof plate and laminating it, wherein the inner airtight film is attached to the plate; and wrapping the outer periphery of the composite airtight layer with Oxford cloth, followed by laminating to obtain the bulletproof plate. The composite airtight layer achieves a synergistic effect through the combination of materials in the inner, middle, and outer layers, achieving a deep integration of airtight protection and dynamic damage resistance. The inner airtight film adheres directly to the surface of the bulletproof insert. Its high ductility absorbs the kinetic energy of the fragments through elastic deformation when the ceramic matrix shatters under impact, preventing rigid damage and penetration. The intermediate fiber fabric adhesive material, through the combination of a three-dimensional woven structure and a viscous matrix, creates a dual energy dissipation mechanism of viscous resistance and fiber mesh reconstruction during tool penetration or impact transmission, effectively blocking the expansion of destructive displacement. The outer airtight film, with its densified surface properties, cooperates with the outer protective fabric to resist environmental erosion and physical scratching, reducing the risk of penetration at the interface source. This gradient response mechanism, from the inside out, allows internal kinetic energy impacts to be flexibly absorbed and external mechanical damage to be rigidly blocked, while the intermediate fiber fabric adhesive material acts as a dynamic buffer zone for bidirectional energy conversion.

[0028] Compared with traditional single-layer packaging, the present invention uses a composite structure airtight layer for packaging, which is small in size and strong in packaging. This allows space for the outermost layer of the plugboard to use Oxford cloth, which is both durable and portable and has a lower cost. This effectively solves the problem of airtight failure caused by easy tearing and scratching, doubly guarantees the airtight effect of the product, and thus extends the service life of the plugboard.

[0039] It should also be understood that the terms used in this description of the embodiments of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the embodiments of the present invention. As used in the description of the embodiments of the present invention and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms unless the context clearly indicates otherwise.

[0040] An embodiment of the present invention provides a method for packaging a bullet-proof plate, comprising the following steps:

[0041] S1. Preparing a composite structure airtight layer: pressing an outer airtight film, a fiber fabric adhesive material, and an inner airtight film in a structure of outer airtight film-fiber fabric adhesive material-inner airtight film.

[0042] The outer airtight film is preferably a hard film to provide rigidity and mechanical strength to the airtight layer to protect it from external scratches and cuts. The outer airtight film is made of at least one of a PE barrier film, an aluminum foil film, a PVC film, and a PET film. The outer airtight film has a thickness of 0.05-0.5 mm, for example, 0.05 mm, 0.15 mm, 0.25 mm, 0.35 mm, 0.45 mm, or 0.5 mm.

[0043] In this embodiment, the outer airtight film is a PE anti-seepage film with a thickness of 0.2 mm.

[0044] The fiber fabric adhesive material is selected from a fiber fabric material with double-sided adhesive properties. This double-sided adhesive property allows for a tight bond between the inner and outer airtight films. Simultaneously, its inherent adhesiveness and internal fiber woven microstructure effectively block the cutting blade's displacement and absorb destructive energy. The fiber fabric adhesive material has a thickness of 0.15-0.8 mm, for example, 0.15 mm, 0.25 mm, 0.35 mm, 0.45 mm, 0.5 mm, 0.65 mm, or 0.8 mm.

[0045] In other embodiments, the fiber fabric adhesive material is selected from at least one of a cloth-based mesh tape, a glass fiber Teflon fiber tape, and a nanofiber tape.

[0046] In this embodiment, the fiber fabric bonding material is a cloth-based mesh tape with double-sided bonding properties and a thickness of 0.4 mm.

[0047] The inner airtight film is preferably a flexible film that provides a sufficient seal while being able to completely adhere to the outer surface of the bulletproof plate to prevent scratches caused by loose material within the plate. The thickness of the inner airtight film is 0.05-0.5 mm, for example, 0.05 mm, 0.15 mm, 0.25 mm, 0.35 mm, 0.45 mm, or 0.5 mm.

[0048] In other embodiments, the material of the inner airtight film is selected from at least one of POF film, PE heat shrink film, PA film, and high-strength aluminum-plastic paper.

[0049] In this embodiment, the inner airtight film is a PA film with a thickness of 0.1 mm.

[0050] In the specific implementation, an automatic cutting machine is first used to cut the outer airtight film, the fiber fabric adhesive material and the inner airtight film into appropriate sizes, and then pressed together according to the structure of outer airtight film-fiber fabric adhesive material-inner airtight film.

[0051] In this embodiment, composite structural airtight layers of two sizes, 420*370 mm and 360*310 mm, were prepared.

[0052] Specifically, first fix the inner airtight film in a square positioning frame, tear off the centrifugal paper on one side of the fiber fabric adhesive material and align it with the inner airtight film, press it down tightly with an air pressure press, the air pressure is 2kpa, and it is maintained for 5s. After unloading the pressure, tear off the centrifugal paper on the upper surface of the fiber fabric adhesive material, align and fit the outer airtight film, press it down tightly with an air pressure press again, the air pressure is 2kpa, and it is maintained for 5s. Unload the pressure and take out to obtain the composite structure airtight layer.

[0053] As can be understood, the composite airtight layer produced in this embodiment achieves a deep fusion of airtight protection and dynamic damage resistance through the functionally coordinated design of the inner, middle, and outer layers. The inner airtight film directly adheres to the surface of the bulletproof insert. Its flexibility and high ductility allow it to absorb the kinetic energy of fragments through elastic deformation when the ceramic matrix shatters under impact, preventing rigid damage and penetration. The middle fiber fabric adhesive material, through its three-dimensional woven structure and viscous matrix, creates a dual energy dissipation mechanism of viscous resistance and fiber mesh reconstruction during tool penetration or impact transmission, effectively blocking the expansion of destructive displacement. The outer airtight film, with its densified surface properties, cooperates with the outer protective fabric to resist environmental erosion and physical scratching, reducing the risk of penetration at the interface source. This gradient response mechanism, from the inside out, allows internal kinetic energy impact to be absorbed by flexibility and external mechanical damage to be blocked by rigidity, while the middle fiber fabric adhesive material acts as a dynamic buffer zone for bidirectional energy conversion.

[0054] S2. Completely wrap the composite structure airtight layer around the surface of the bulletproof insert and press it together, wherein the inner airtight film is in contact with the bulletproof insert.

[0055] The material of the bulletproof insert can be a ceramic plate made of aluminum oxide, silicon carbide, silicon nitride, boron carbide, tungsten carbide, tungsten boride or a composite thereof.

[0056] In this embodiment, the size of the bulletproof insert is 330*280 mm. The size of the first-size composite structure airtight layer is 420*370 mm; the size of the second-size composite structure airtight layer is 360*310 mm.

[0057] In this embodiment, the specific operations of step S2 include:

[0058] Prepare the above-mentioned two sizes of composite structure airtight layers, first use acrylic non-woven adhesive to coat the inner layer airtight film of the composite structure airtight layer; according to the structure of "first size composite structure airtight layer-bulletproof insert plate-second size composite structure airtight layer", place the bulletproof insert plate between the first size composite structure airtight layer and the second size composite structure airtight layer, and perform high-temperature press-sealing on the first size composite structure airtight layer and the second size composite structure airtight layer based on the reserved amount of the second size composite structure airtight layer; apply acrylic non-woven adhesive to the remaining amount of the first size composite structure airtight layer after edge sealing, fold it over to the surface of the second size composite structure airtight layer, press and cure, and complete the wrapping.

[0059] In this embodiment, the length of a single side of the pressed edge is 3 cm, the pressing temperature is 120° C., and the pressing and curing time is 6 hours.

[0060] S3. Wrap the outer periphery of the composite structure airtight layer with Oxford cloth and press it together to obtain the bulletproof plate.

[0061] In this embodiment, in step S3, the Oxford cloth has two sizes, namely a first size Oxford cloth of 420*370 mm and a second size Oxford cloth of 360*310 mm.

[0062] In this embodiment, the specific operations of step S3 include:

[0063] Prepare the above-mentioned two sizes of Oxford cloth, first use acrylic non-woven adhesive to coat the inner surface of the Oxford cloth; according to the structure of "first size Oxford cloth - bulletproof insert wrapped composite structure airtight layer - second size Oxford cloth", place the bulletproof insert wrapped composite structure airtight layer between the first size Oxford cloth and the second size Oxford cloth, sew and seal the first size Oxford cloth and the second size Oxford cloth based on the reserved amount of the second size Oxford cloth; apply acrylic non-woven adhesive to the remaining amount of the first size Oxford cloth after edge sealing, fold it over and place it on the surface of the second size Oxford cloth, press and cure, and complete the wrapping.

[0064] In this embodiment, the 3 cm edge of the Oxford cloth is sewn and sealed using aramid thread of an automatic industrial sewing machine, and the pressing and curing time is 6 hours.

[0065] See also Figure 2 , Figure 2A schematic diagram of the protection of the bulletproof plate provided by an embodiment of the present invention. When the bulletproof plate obtained by the packaging method of this embodiment is subjected to external forces, such as external puncture and cutting, the Oxford cloth and the outer hard airtight film of the composite structure airtight layer consume the cutting energy. When the destructive force reaches the intermediate fiber fabric adhesive material, its own viscosity and internal fiber woven microstructure can effectively block the cutting displacement of the tool and absorb the destructive energy, preventing it from damaging the inner flexible airtight film. When the bulletproof insert is damaged by external forces and fragments are generated, the inner flexible airtight film will absorb the ceramic kinetic energy through its own flexible tensile deformation. When the damage to the bulletproof insert reaches the intermediate fiber fabric adhesive material, the viscosity of the intermediate fiber fabric material and the internal fiber woven microstructure also have the effect of intercepting ceramic fragments, preventing the outer airtight film of the airtight layer from being damaged. The bulletproof plate encapsulated by the composite structure provided by the present invention achieves dual airtight protection based on the above principles. Figure 3 This is a schematic diagram of the external / internal force damage of the bulletproof plate provided in an embodiment of the present invention. As can be seen from the figure, the anti-puncture / anti-cut performance is good.

[0066] In this embodiment, the Oxford cloth is positioned as the outermost layer of the bulletproof plate. The Oxford cloth's wear resistance, combined with the density of the outer rigid film of the composite airtight layer, creates a primary barrier against external scratches, significantly reducing the risk of surface tearing caused by contact with sharp objects. Compared to traditional single-layer packaging materials, the composite structure packaging of the present invention overcomes the limitations of a single performance through the functional design of the material interface. The combination of the composite airtight layer and the Oxford cloth maintains lightweight properties while addressing the flaw of traditional polymer films that are susceptible to scratching through surface densification. The intermediate fabric adhesive material forms an adaptive energy absorption path through viscoelastic deformation and fiber network reconstruction during dynamic damage. The ductility of the inner flexible film compensates for the lack of impact toughness of the rigid material. The synergistic effect of these three factors not only extends the airtight stability of the bulletproof plate in extreme temperature and humidity environments, but also, by enhancing the structural damage resistance, ensures both interface integrity and long-term sealing in complex physical impact scenarios, thereby expanding the lifecycle applicability of protective equipment.

[0067] The present invention also provides a bulletproof plate, which is encapsulated by the bulletproof plate encapsulation method described in the above embodiment. Figure 1 , which is a partial structural diagram of a bulletproof plate according to an embodiment of the present invention. As can be seen from the figure, the bulletproof plate according to this embodiment comprises a bulletproof insert 1, a composite airtight layer covering the bulletproof insert 1, and an outermost layer of Oxford cloth 3. The composite airtight layer comprises, from the inside out, an outer airtight film 23, a fiber fabric adhesive material 22, and an inner airtight film 21; the inner airtight film 21 is bonded to the bulletproof insert 1.

[0068] The bulletproof plate of this embodiment utilizes the composite structure airtight layer to wrap the bulletproof insert. Through the synergistic combination of different materials and properties, it can meet the requirements of aging resistance, high reliability, sealing, and shape retention. At the same time, the middle layer of fabric adhesive material blocks and reduces the cutting energy of sharp weapons, thereby enhancing the airtightness of the airtight layer on both the inner and outer surfaces to prevent airtightness from being damaged, doubly ensuring the airtightness of the product, and giving the product the requirements of dual tear resistance, high reliability, and long life for the inner and outer airtight layers. This compact airtight layer structure allows space for the outermost layer of the bulletproof insert to be made of Oxford cloth, which is both durable and portable, and has a lower cost. This effectively solves the problem of airtight failure caused by easy tearing and scratching, doubly ensuring the airtightness of the product, and thus extending the service life of the insert.
