Description

Technical Field

[0001] This application relates to the field of individual soldier protective equipment technology, and in particular to a bulletproof insert. Background Technology

[0002] Bulletproof inserts are the core components of bulletproof vests, mainly used to block the penetration of bullets or shrapnel. Their performance is directly related to the user's life safety. Currently, bulletproof inserts on the market, especially ceramic composite bulletproof inserts, are usually composed of hard ceramic sheets and backing fiber composite materials (such as PE and aramid).

[0003] Existing technologies for bulletproof plates have several shortcomings in their surface treatment methods. Most products focus only on core bulletproof performance, neglecting surface durability under complex battlefield environments or harsh weather conditions. Exposed ceramic edges are prone to cracking due to impacts, directly affecting the overall bulletproof effect. The plate surface lacks protective design and is deficient in waterproofing, moisture resistance, and chemical corrosion resistance. During long-term storage or use, moisture and harmful substances can easily penetrate the interior, leading to performance degradation of the fiber backing material.

[0004] Regarding the aforementioned technologies, the inventors believe that they have the following defects: the ceramic edges are exposed and lack protective design, making them prone to cracking due to impacts, which affects the bulletproof performance; the surface of the plate lacks protection and does not have waterproof, moisture-proof, or corrosion-proof capabilities, leading to a decrease in the performance of the bulletproof insert. Utility Model Content

[0005] To address the issues of insufficient protection on the substrate surface, making it prone to cracking due to impacts, and the lack of waterproof, moisture-proof, and corrosion-resistant capabilities, this application provides a bulletproof insert.

[0006] The bulletproof insert provided in this application adopts the following technical solution: A bulletproof insert includes a base plate, with an edge layer fixed to the periphery of the base plate to prevent the base plate from being bumped, a bottom fabric layer fixed to the surface of the base plate to prevent the base plate from rubbing, and an adhesive backing layer fixed to the side of the bottom fabric layer facing the base plate to form a sealing area after heating.

[0007] By adopting the above technical solution, the edge-wrapping layer around the substrate can effectively protect the substrate, prevent the substrate from being rubbed or bumped, and also prevent the substrate from hurting the user, thus providing a certain degree of protection. The bottom fabric layer is used to increase the friction between the substrate and the backing, preventing the substrate and the backing from shifting. The adhesive layer is used to firmly fix the bottom fabric layer to the substrate, forming a sealed area after heating, which can prevent moisture, chemicals and other harmful substances from penetrating into the substrate, further improving the bulletproof insert's resistance and service life in complex environments.

[0008] Optionally, the substrate is an alumina ceramic composite plate, the substrate is arc-shaped, and chamfers are formed on all four sides of the substrate.

[0009] By adopting the above technical solution, the alumina ceramic composite plate has extremely high hardness, which can directly shatter or deflect bullets and fragments, quickly consume their kinetic energy, and block penetration. Moreover, the alumina ceramic composite plate is relatively lightweight, and the base plate body has a certain curvature to fit the front of the human body, which can improve the fit of wearing it and prevent the bulletproof plate from shaking or shifting during activities. At the same time, the chamfered corners set around the base plate can prevent the base plate from injuring the user during human activities.

[0010] Optionally, a TPU coating for preventing liquid penetration is fixed to the side of the base fabric layer away from the substrate, a camouflage coating is fixed to the side of the TPU coating away from the base fabric layer, and an anti-aging coating for UV protection is fixed to the side of the camouflage coating away from the TPU coating.

[0011] By adopting the above technical solution, the TPU coating fixed on the side of the bottom fabric away from the substrate can effectively prevent liquid penetration and prevent moisture from entering the bulletproof insert. The camouflage coating gives the bulletproof insert camouflage properties, making it suitable for military combat scenarios. The outermost anti-aging coating can resist ultraviolet rays and prevent the camouflage coating and TPU coating from aging due to ultraviolet radiation.

[0012] Optionally, a buffer layer for shock absorption is fixed to one side of the substrate.

[0013] By adopting the above technical solution, when a bullet or fragment impacts the bulletproof insert, the base plate first bears the impact force, while the buffer layer that fits in front of the human chest can buffer and dampen the impact force, effectively reducing the damage to the human chest caused by the impact force generated by bullet impact, etc.

[0014] In summary, this application includes at least one of the following beneficial technical effects: 1. Fixing the edge layer around the substrate can effectively prevent damage to the substrate edge due to bumps. After covering the substrate surface with the base cloth layer, it is processed by a high-frequency heat sealing machine according to a specific process (temperature 150℃, pressure 0.6MPa, hot pressing for 5 seconds) to form a solid and sealed hot edge structure, which can eliminate the path of liquid intrusion. The dense surface of the base cloth layer can also block the adhesion and penetration of smoke particles and slight chemical reagents, giving the substrate reliable waterproof, moisture-proof and corrosion-proof performance. 2. On the side of the base fabric away from the substrate, the TPU coating, camouflage coating, and anti-aging coating are sequentially fixed: The TPU coating can enhance the hydrophobic effect and further block liquid penetration; the camouflage coating is precisely adapted to the tactical camouflage requirements of multi-terrain operations; the anti-aging coating can effectively resist ultraviolet radiation and delay the aging and fading of the base fabric, TPU coating, and camouflage coating.

Detailed Implementation

[0017] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0018] This application discloses a bulletproof insert.

[0019] Reference Figure 1 and Figure 2 A bulletproof insert includes a base plate 1, an edging layer 2 fixed around the base plate 1, a base fabric layer 3 fixed to the surface of the base plate 1, and an adhesive backing layer 4 fixed to the base fabric layer 3. The base plate 1 itself is used for bulletproof protection; the edging layer 2 is fixed around the base plate 1 to prevent damage from impacts that could affect its bulletproof performance; the base fabric layer 3 preferably uses high-strength nylon Oxford cloth or polyester velvet fabric as the base material, which can effectively prevent friction and scratches on the surface of the base plate 1. Simultaneously, the dense surface of the base fabric layer 3 can effectively block the adhesion and penetration of smoke particles and minor chemical reagents on the battlefield, and is easy to clean; the adhesive backing layer 4 is fixed to the side of the base fabric layer 3 facing the base plate 1, firmly adhering the base fabric layer 3 to the base plate 1.

[0020] Reference Figure 1 and Figure 2During processing, the edge-binding layer 2 is first fixed to the perimeter of the substrate 1 with glue. Then, the bottom fabric layer 3 is cut to a suitable size and fixed to the surface of the substrate 1 by the backing adhesive layer 4 on the bottom fabric layer 3. After the bottom fabric layer 3 is fixed, it is placed under a high-frequency heat sealer. Using a special mold, the edge is subjected to heat pressing for 5 seconds at a temperature of 150 degrees Celsius and a pressure of 0.6 MPa. During this process, the bottom fabric layer and the backing adhesive layer 4 at the edge melt. After pressure and cooling, a solid and smooth hot-pressed edge sealing area with a width of about 3-5 mm is formed. This hot-pressed edge eliminates the path of water intrusion and avoids the risk that traditional stitching may be worn through.

[0021] Reference Figure 1 and Figure 3 The substrate 1 is an alumina ceramic composite plate. The substrate 1 body has a certain curvature, and all four sides of the substrate 1 are chamfered by 5. The alumina ceramic composite plate is lightweight and has extremely high hardness, which can directly shatter or deflect bullets and fragments, quickly dissipating their kinetic energy. The curvature of the substrate 1 makes it fit the human body better, improving the user's comfort when wearing it. The chamfered edges of the substrate 1 prevent the user from being uncomfortable and affecting the user experience.

[0022] Reference Figure 2 A TPU coating 6 is fixed on the base fabric layer 3, a camouflage coating 7 is fixed on the TPU coating 6, and an anti-aging coating 8 is fixed on the camouflage coating 7. The TPU coating 6 is fixed on the side of the base fabric layer 3 away from the substrate 1 to repel water and prevent liquid from penetrating to the surface of the substrate 1. The camouflage coating 7 is fixed on the side of the TPU coating 6 away from the base fabric layer 3 to meet the tactical camouflage requirements of modern multi-terrain warfare. The anti-aging coating 8 is fixed on the side of the camouflage layer away from the TPU coating 6 to delay material aging and color fading caused by sunlight exposure, and also to prevent the TPU coating 6 and the camouflage coating 7 from aging.

[0023] Reference Figure 4 and Figure 5 A buffer layer 9 is provided on the substrate 1. The buffer layer 9 is provided on the side of the substrate 1 facing the chest of the human body to reduce impact and improve the comfort of the user when wearing it.

[0024] The implementation principle of a bulletproof insert in this embodiment is as follows: When manufacturing the bulletproof insert, the edging layer 2 is first fixed to the perimeter of the substrate 1 with adhesive. Then, the base fabric layer 3 is cut to a suitable size. Using the adhesive backing layer 4 on the base fabric layer 3, the base fabric layer 3 is adhered to the curved surface of the substrate 1. After the base fabric layer 3 is adhered, the substrate 1 is placed under a high-frequency heat sealer. Using a special mold, the edges are subjected to heat pressing for 5 seconds at a temperature of 150 degrees Celsius and a pressure of 0.6 MPa. During this process, the nylon fabric and adhesive backing layer 4 at the edges melt. After pressure and cooling, a solid and smooth heat-sealed area with a width of approximately 3-5 mm is formed. To effectively prevent liquid from seeping into the substrate 1 from the edge of the base fabric layer 3, a TPU coating 6 is sprayed and fixed onto the surface of the base fabric layer 3 during the manufacturing process to prevent liquid from penetrating to the substrate surface. A camouflage coating 7 is sprayed and fixed onto the TPU coating 6 to meet the user's tactical needs in various terrains. An anti-aging coating 8 is sprayed and fixed onto the camouflage coating 7 to protect the base fabric layer 3, TPU coating 6, and camouflage coating 7 from aging and fading due to ultraviolet radiation. After the base fabric layer 3 is processed, a buffer layer 9 is glued to the side of the substrate 1 facing the user's chest to reduce the impact of bullets, fragments, etc.
