[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0021] EMBODIMENT

[0022] As Figs. 1-2 Shown, the utility model discloses an embodiment to propose a kind of bubble cotton with good shock resistance, including bubble cotton body 1, overall structure, as the carrier of other components, provide the shape and support overall structure for entire bubble cotton;The upper and lower end surfaces of the bubble cotton body 1 are all provided with matrix groove 2, the inside of the bubble cotton body 1 is uniformly provided with aerogel ball 3, while filling vertical reinforcement 4 and horizontal reinforcement 5 in the inside of bubble cotton body 1;

[0023] The role of matrix groove 2

[0024] Increase friction: the existence of matrix groove 2 increases the contact area and friction between bubble cotton and protected article, so that bubble cotton can better fix article when packing article, reduce the displacement of article due to shaking in transportation or storage process, so as to reduce the risk of collision.

[0025] Stress Dispersion: When the foam is subjected to external pressure or vibration, the matrix groove 2 can provide a certain deformation space. It can make the stress more evenly distributed on the surface of the foam, avoid stress concentration in local areas, prevent local over-deformation or damage of the foam, and improve the overall compression and shock resistance of the foam.

[0026] The Role of Aerogel Spheres 3

[0027] High-efficiency energy absorption and shock absorption: Aerogel has the characteristics of high porosity and low density, and the aerogel spheres 3 can effectively absorb and disperse energy when the foam is subjected to vibration. The porous structure inside the aerogel can convert vibration energy into heat energy or other forms of energy, thereby greatly reducing the impact of vibration on the protected items and providing good cushioning protection for the items.

[0028] Lightweight: Aerogel itself has very low density, significantly improving its shockproof performance without increasing the weight of the foam too much, allowing the foam to maintain a relatively light mass while ensuring good protection effect, facilitating its application in scenarios with certain weight requirements, such as aerospace equipment transportation packaging, etc.

[0029] The Role of Vertical and Horizontal Reinforcing Elements

[0030] Enhanced Structural Strength: Nanofiber filaments have high strength and toughness, distributed in the form of S inside the foam body 1, providing additional support to the foam in both vertical and horizontal directions. They can enhance the overall structural strength of the foam, making it less prone to severe deformation or rupture when subjected to external pressure or impact, maintaining the shape stability of the foam and better protecting the internal items.

[0031] Synergistic Energy Absorption and Stress Dispersion: In cooperation with the aerogel spheres 3, when the foam is subjected to vibration or impact, the reinforcing elements can transmit stress to the aerogel spheres 3, allowing the aerogel spheres 3 to better absorb energy; at the same time, they themselves can absorb a part of the energy through elastic deformation and disperse the energy to the entire foam structure, further improving the shockproof performance of the foam.

[0032] The Role of Halogen-based Flame Retardant Coating

[0033] Flame Retardation: In the presence of a fire source, the halogen-based flame retardant coating can release substances with flame-retardant properties, preventing or delaying the spread of flames on the surface of the foam, preventing the foam itself from burning, and protecting the packaged items from fire threats, especially suitable for environments with high fireproof requirements, such as electronic device packaging, flammable material transportation packaging, etc.

[0034] Certain Degree of Protection Enhancement: It can prevent the erosion of chemical substances, moisture, etc. in the external environment to the foam body 1 to a certain extent, serving as an additional protective layer, prolonging the service life of the foam, and indirectly maintaining the shockproof performance of the foam.

[0035] The role of high temperature resistant sealant

[0036] High-temperature stability: This prevents the aerogel balls 3, nanofiber filaments, and other components within the foam from being affected by high temperatures and causing performance degradation or damage. For example, this prevents the aerogel balls 3 from structurally breaking down due to high temperatures and losing their energy-absorbing and shock-absorbing capabilities, ensuring that the foam maintains good shock-absorbing properties even in high-temperature environments.

[0037] Improved sealing: Effectively prevents dust, water, moisture and other impurities from entering the foam. Water ingress may affect the performance of the aerogel balls 3, and dust and other impurities may damage the internal structure of the foam. Sealing can maintain the integrity and cleanliness of the foam's internal structure, ensuring long-term stable operation of all components and maintaining the overall performance of the foam.

[0038] like Fig. 2 As shown, in some embodiments, the vertical reinforcements 4 and transverse reinforcements 5 are nanofiber filaments. Nanofiber filaments have excellent mechanical properties, with significantly improved strength and modulus compared to ordinary fiber materials. This allows the vertical reinforcements 4 and transverse reinforcements 5 to withstand greater stress when the foam is subjected to external forces without breaking or excessively deforming.

[0039] like Fig. 2 As shown, in some embodiments, the vertical reinforcements 4 and the transverse reinforcements 5 are both S-shaped. This S-shaped structure creates a complex, tortuous path within the foam. When vibration or impact energy is transmitted to the foam, the S-shaped reinforcement guides the energy along its tortuous path, increasing the distance and time the energy travels within the foam, thereby continuously consuming and dissipating the energy during propagation. This is like a complex maze, where energy is constantly reflected and refracted, eventually gradually weakening. This effectively reduces the energy intensity transmitted to the protected object and significantly enhances the foam's shockproofing effectiveness.

[0040] like Fig. 2 As shown, in some embodiments, the outer surface of the foam body 1 is provided with a halogen-based flame-retardant coating, which significantly improves the safety of the foam in fire scenarios.

[0041] like Fig. 2 As shown, in some embodiments, the edge of the foam body 1 is sealed with a high-temperature resistant sealant to improve the stability and sealing of the foam in a high-temperature environment; the high-temperature resistant sealant forms an effective barrier at the edge of the foam body 1, which can prevent impurities such as dust, water, and moisture from entering the interior of the foam.

[0042] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for the skilled in the art, it still can be modified, or for the equivalent replacement of part of the technical features of the technical solutions recorded in the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, shall be included within the scope of the present application.
