Description

Technical Field

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

[0002] With its dense structure, low air permeability and chemical stability, airtight materials play a key role in building sealing, medical packaging, electronic equipment protection and other fields. Its core function is to effectively block gas penetration. As a core component of protective equipment, bulletproof inserts must not only withstand extreme physical loads such as ballistic impact and knife penetration, but also maintain stable performance in harsh environments such as -40°C to 80°C temperature range, high humidity salt spray, sand and dust erosion and underwater pressure. At the same time, it must meet the strict verification of multi-angle shooting and environmental pretreatment protection performance of NIJ0101.06, MIL-STD-662F and other standards. Among them, material aging and interface corrosion caused by long-term temperature and humidity fluctuations are the main causes of the attenuation of protective performance.

[0003] The existing packaging technology for bulletproof inserts has significant limitations. The mainstream packaging methods include: packaging with ultra-high molecular weight polyethylene non-woven fabrics. Although this sewn structure has basic anti-cutting capabilities, the gaps in its woven structure are prone to form water vapor penetration channels, making it difficult to meet the sealing requirements of high temperature and high humidity environments and the full waterproof requirements of underwater combat, and the complex processing technology leads to rising costs; packaging with polyurea coatings. Although this coating process improves the surface waterproofness, the weight increase brought by the high-density coating is in conflict with the lightweight demand for bulletproof inserts. At the same time, the rigid coating is prone to cracks under impact, causing secondary leakage. More importantly, neither of these two methods effectively coordinates airtight protection and mechanical damage resistance - although traditional airtight materials (such as polymer films) have excellent barrier properties, they are easily scratched and fail due to their weak puncture resistance; and although high-strength fiber materials improve damage resistance, they sacrifice sealing stability due to the openness of the structure. This split in material properties makes it difficult for the existing packaging layer to maintain long-term protective performance under complex stress coupling. It is urgent to develop new composite packaging methods to achieve the coordinated optimization of airtight durability and dynamic damage resistance. Summary of the invention

[0007] A further technical solution thereof is that the specific operation of step S2 includes: Place the bulletproof plate between the first-size composite structure airtight layer and the second-size composite structure airtight layer according to the structure of "first-size composite structure airtight layer - bulletproof plate - second-size composite structure airtight layer", and press and seal the edges of 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 adhesive to the surplus after sealing the edge of the first-size composite structure airtight layer, then fold it over to the surface of the second-size composite structure airtight layer, and press and cure to complete the wrapping.

[0008] A further technical solution thereof is that the pressing and sealing is carried out by means of high-temperature pressing, and the temperature is 110-120 °C.

[0009] A further technical solution thereof is that in step S3, the Oxford cloth has two sizes, namely the first-size Oxford cloth and the second-size Oxford cloth; one side of the first-size Oxford cloth is 2-4 cm larger than one side of the second-size Oxford cloth, and one side of the second-size Oxford cloth is 2-4 cm larger than one side of the bulletproof plate.

[0010] A further technical solution thereof is that the specific operation of step S3 includes: Place the bulletproof plate wrapped with the composite structure airtight layer between the first-size Oxford cloth and the second-size Oxford cloth according to the structure of "first-size Oxford cloth - bulletproof plate wrapped with the composite structure airtight layer - second-size Oxford cloth", and sew and seal the edges of the first-size Oxford cloth and the second-size Oxford cloth based on the reserved amount of the second-size Oxford cloth; Apply adhesive to the surplus after sealing the edge of the first-size Oxford cloth, then fold it over to the surface of the second-size Oxford cloth, and press and cure to complete the wrapping.

[0018] Compared with the prior art, the technical effects that can be achieved by the embodiments of the present invention include: The bulletproof plate encapsulation method provided by the present invention includes the steps of preparing a composite structure airtight layer: laminating an outer airtight film, a fiber fabric bonding material, and an inner airtight film in the structure of outer airtight film - fiber fabric bonding material - inner airtight film; completely wrapping and laminating the surface of the bulletproof insert with the composite structure airtight layer, wherein the inner airtight film is attached to the bulletproof insert; wrapping the outer periphery of the composite structure airtight layer with Oxford cloth and laminating to obtain a bulletproof plate. The composite structure airtight layer exerts a synergistic effect through the material compounding of the inner, middle, and outer layers, realizing the deep integration of airtight protection and dynamic anti-damage. The inner airtight film is directly attached to the surface of the bulletproof insert, and its high ductility can absorb the kinetic energy of fragments through elastic deformation when the ceramic matrix is impacted and broken, avoiding rigid penetration; the intermediate fiber fabric bonding material forms a dual energy dissipation mechanism of viscous resistance and fiber network reconstruction during the process of tool puncture or impact transmission, effectively blocking the expansion of destructive displacement; the outer airtight film, relying on its densified surface characteristics, cooperates with the external protective fabric to resist environmental erosion and physical scratching, reducing the penetration risk from the interface source. This gradient response mechanism from the inside to the outside flexibly dissipates the internal kinetic energy impact and rigidly blocks the external mechanical damage, while the intermediate fiber fabric bonding material becomes a dynamic buffer zone for two-way energy conversion.

[0019] Compared with traditional single-layer encapsulation, the present invention uses a composite structure airtight layer for encapsulation, which is small in volume and has strong wrapping ability, enabling the outermost layer of the plug board to have space to adopt Oxford cloth that combines durability, portability and lower cost, effectively solving the problem of airtight failure caused by easy tearing and scratching, and double guaranteeing the airtight effect of the product, thereby extending the service life of the plug board.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Similar component labels in the drawings represent similar components. Obviously, the following described embodiments are only a part of the embodiments of the present invention, rather than all embodiments.

[0025] It should be understood that when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, wholes, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components, and / or their combinations.

[0026] It should also be understood that the terms used in the specification 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 specification of the embodiments of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an", and "the" are intended to include the plural forms.

[0027] The embodiments of the present invention provide a method for encapsulating a bulletproof plate, comprising the following steps: S1. Prepare a composite structure airtight layer: Press the outer airtight film, the fiber fabric adhesive material, and the inner airtight film in the structure of outer airtight film - fiber fabric adhesive material - inner airtight film.

[0028] The outer airtight film is preferably a rigid film, which provides stiffness and mechanical strength for the airtight layer to resist external scraping and cutting. The material of the outer airtight film is selected from at least one of a PE anti-seepage film, an aluminum foil film, a PVC film, and a PET film. The thickness of the outer airtight film is 0.05 - 0.5 mm, such as 0.05 mm, 0.15 mm, 0.25 mm, 0.35 mm, 0.45 mm, 0.5 mm.

[0029] In this embodiment, the outer airtight film is a PE anti-seepage film with a thickness of 0.2 mm.

[0030] The fiber fabric adhesive material is selected from fiber fabric materials with double-sided adhesive properties. The double-sided adhesive property is used to tightly bond the inner and outer airtight films. At the same time, its own adhesiveness and the internal fiber weaving microstructure can effectively block the cutting displacement of the tool and absorb the destruction energy. The thickness of the fiber fabric adhesive material is 0.15 - 0.8 mm, such as 0.15 mm, 0.25 mm, 0.35 mm, 0.45 mm, 0.5 mm, 0.65 mm, 0.8 mm.

[0031] In other embodiments, the fiber fabric adhesive material is selected from at least one of a cloth-based grid tape, a fiberglass Teflon fiber tape, and a nanofiber tape.

[0032] In this embodiment, the fiber fabric adhesive material is a cloth-based grid tape with double-sided adhesive properties and a thickness of 0.4 mm.

[0033] The inner airtight film is preferably a flexible film, which can fully conform to the outer surface of the bulletproof plate while meeting the sealing performance, preventing scratching caused by the loosening of the internal materials of the bulletproof plate. The thickness of the inner airtight film is 0.05 - 0.5 mm, such as 0.05 mm, 0.15 mm, 0.25 mm, 0.35 mm, 0.45 mm, 0.5 mm.

[0034] In other embodiments, the material of the inner airtight film is selected from at least one of POF film, PE heat shrinkable film, PA film, and high-strength aluminum plastic paper.

[0035] In this embodiment, the inner airtight film is a PA film with a thickness of 0.1 mm.

[0036] In specific implementation, first use an automatic cutting machine to cut the outer airtight film, fiber fabric bonding material, and inner airtight film into appropriate sizes, and then press them according to the structure of outer airtight film - fiber fabric bonding material - inner airtight film.

[0037] This embodiment produces composite structure airtight layers in two size specifications of 420*370 mm and 360*310 mm.

[0038] Specifically, first fix the inner airtight film in a square positioning frame, tear off the centrifugal paper on one side of the fiber fabric bonding material and align it to fit on the inner airtight film, press it tightly through a pneumatic press, with a pressure of 2 kPa and keep it for 5 s. After depressurization, tear off the upper surface centrifugal paper of the fiber fabric bonding material, align and fit the outer airtight film, and press it tightly again through a pneumatic press, with a pressure of 2 kPa and keep it for 5 s. After depressurization, take out to obtain the composite structure airtight layer.

[0039] It can be understood that the composite structure airtight layer prepared in this embodiment realizes the deep integration of airtight protection and dynamic anti-damage through the functionalized collaborative design of the inner, middle, and outer layers. The inner airtight film directly adheres to the surface of the bulletproof plate, and its flexibility and high ductility can absorb the kinetic energy of fragments through elastic deformation when the ceramic matrix is impacted and broken, avoiding rigid penetration; the middle fiber fabric bonding material forms a dual energy dissipation mechanism of viscous resistance and fiber network reconstruction during the process of tool puncture or impact transmission, effectively blocking the expansion of destructive displacement; the outer airtight film, relying on its densified surface characteristics, collaborates with the external protective fabric to resist environmental erosion and physical scratching, reducing the penetration risk from the interface source. This gradient response mechanism from the inside to the outside enables the internal kinetic energy impact to be flexibly dissipated, the external mechanical damage to be rigidly blocked, and the middle fiber fabric bonding material to become a dynamic buffer zone for two-way energy conversion.

[0040] S2. Completely wrap and press the surface of the bulletproof plate with the composite structure airtight layer, wherein the inner airtight film adheres to the bulletproof plate.

[0041] The material of the bulletproof insert can be a ceramic plate made of alumina, silicon carbide, silicon nitride, boron carbide, tungsten carbide, tungsten boride or their composites, etc.

[0042] In this embodiment, the size of the bulletproof insert is 330*280mm. The size of the first-size composite structure airtight layer is 420*370mm; the size of the second-size composite structure airtight layer is 360*310mm.

[0043] In this embodiment, the specific operation of step S2 includes: Prepare the composite structure airtight layers of the above two sizes. First, coat the inner airtight film of the composite structure airtight layer with acrylic non-woven adhesive; place the bulletproof insert between the first-size composite structure airtight layer and the second-size composite structure airtight layer according to the structure of "first-size composite structure airtight layer - bulletproof insert - 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; coat the remaining amount after sealing the edge of the first-size composite structure airtight layer with acrylic non-woven adhesive and then fold it to the surface of the second-size composite structure airtight layer, and press and cure to complete the wrapping.

[0044] In this embodiment, the unilateral length of the press-sealing is 3cm, the pressing temperature is 120°C, and the pressing and curing time is 6h.

[0045] S3. Wrap the outer periphery of the composite structure airtight layer with Oxford cloth, and obtain a bulletproof plate after pressing.

[0046] In this embodiment, in the step S3, the Oxford cloth has two sizes, which are the first-size Oxford cloth 420*370mm and the second-size Oxford cloth 360*310mm respectively.

[0047] In this embodiment, the specific operation of the step S3 includes: Prepare the Oxford cloth of the above two sizes. First, coat the inner surface of the Oxford cloth with acrylic non-woven adhesive; place the bulletproof insert wrapped with the composite structure airtight layer between the first-size Oxford cloth and the second-size Oxford cloth according to the structure of "first-size Oxford cloth - bulletproof insert wrapped with the composite structure airtight layer - second-size Oxford cloth", and perform sewing and sealing on the first-size Oxford cloth and the second-size Oxford cloth based on the reserved amount of the second-size Oxford cloth; coat the remaining amount after sealing the edge of the first-size Oxford cloth with acrylic non-woven adhesive and then fold it to the surface of the second-size Oxford cloth, and press and cure to complete the wrapping.

[0048] In this embodiment, the sewing and sealing uses an automatic industrial sewing machine with aramid thread to perform sewing and sealing treatment on the 3cm edge reserved by the Oxford cloth, and the pressing and curing time is 6h.

[0049] See Figure 2 , Figure 2 which is a schematic diagram of the protection of the bulletproof plate provided by the embodiment of the present invention. The bulletproof plate obtained by the encapsulation method of this embodiment, when subjected to external forces, such as external puncture and cutting, the outer rigid airtight film of the Oxford cloth and the composite structure airtight layer consumes the cutting energy. When the destructive force reaches the intermediate fiber fabric bonding material, its own viscosity and the internal fiber weaving microstructure can effectively block the cutting displacement of the tool and absorb the destructive energy, preventing the damage to the inner flexible airtight film; when fragments are generated due to external damage to the bulletproof insert plate, the inner flexible airtight film will absorb the kinetic energy of the ceramic through its own flexible stretching deformation. When the damage to the bulletproof insert plate reaches the intermediate fiber fabric bonding material, the viscosity and the internal fiber weaving microstructure of the intermediate fiber fabric material also have the effect of intercepting ceramic fragments, preventing the damage to the airtight film on the outer layer of the airtight layer. The bulletproof plate with a composite structure encapsulation provided by the present invention realizes double airtight protection based on the above principle. Figure 3 which is a schematic diagram of the external / internal force damage situation of the bulletproof plate provided by the embodiment of the present invention. As can be seen from the figure, the bulletproof plate has good puncture / cutting resistance.

[0050] In this embodiment, the Oxford cloth is located on the outermost layer of the bulletproof plate. By using the wear-resistant characteristics of the Oxford cloth and the compactness of the outer rigid film of the composite structure airtight layer, a first barrier against external cutting is formed, significantly reducing the risk of tearing on the surface caused by contact with sharp objects. Compared with traditional single-layer encapsulation materials, the composite structure encapsulation of the present invention breaks through the limitations of single performance through the functional design of the material interface. The combination of the composite structure airtight layer and the Oxford cloth not only maintains the lightweight characteristics, but also solves the defect that traditional polymer films are easily scratched through surface densification; the intermediate fabric bonding material forms an adaptive energy absorption path through viscoelastic deformation and fiber network reconstruction during the dynamic damage process; the ductility of the inner flexible film makes up for the lack of impact toughness of rigid materials. Under the synergistic effect of the three, not only the airtight stability of the bulletproof insert plate in extreme temperature and humidity environments is extended, but also through the improvement of the structural damage resistance ability, the product has both interface integrity and long-term sealing performance in complex physical impact scenarios, thereby expanding the applicable boundary of the full life cycle of the protection equipment.

[0051] The present invention also provides a bulletproof plate, which is encapsulated and prepared by the encapsulation method of the bulletproof plate described in the above embodiment. See Figure 1 , which is a partial structural schematic diagram of the bulletproof plate provided by the embodiment of the present invention. As can be seen from the figure, the bulletproof plate provided by this embodiment includes a bulletproof insert plate 1, a composite structure airtight layer covering the bulletproof insert plate 1, and an Oxford cloth 3 covering the outermost layer. The composite structure airtight layer is successively composed of an outer airtight film 23, a fiber fabric bonding material 22, and an inner airtight film 21 from the inside to the outside; the inner airtight film 21 is attached to the bulletproof insert plate 1.

[0052] For the bulletproof plate of this embodiment, the above-mentioned composite structure airtight layer is used to wrap the bulletproof insert plate. Through the coordinated cooperation of different materials and performances, it can meet the requirements of the bulletproof insert plate for anti-aging, high reliability, sealing and shape retention. At the same time, it can reduce the cutting energy of sharp tools by blocking through the middle-layer fabric bonding material, so as to improve the airtight destruction resistance of both sides inside and outside the airtight layer, double-guarantee the airtight effect of the product, and endow the product with the requirements of double tear resistance, high reliability and long life inside and outside the airtight layer. This airtight layer has a compact structure, so that the outermost layer of the bulletproof insert plate has space to adopt Oxford cloth with both durability and portability and lower cost, effectively solving the problem of airtight failure caused by easy tearing and easy scratching, double-guaranteeing the airtight effect of the product, and thus extending the service life of the insert plate.
