[0017] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0018] This application discloses a shock-absorbing cardboard board. (Refer to...) Figure 1-3A shock-absorbing cardboard board includes a shock-absorbing layer 2, a cardboard layer 3, and a temperature control layer 6. The shock-absorbing layer 2 is disposed on top of the cardboard layer 3, and a capsule layer 201 is disposed inside the shock-absorbing layer 2. A protective layer 1 is disposed on top of the shock-absorbing layer 2. A heat insulation layer 4 is disposed on the bottom of the cardboard layer 3. A repair layer 5 is disposed on the bottom of the heat insulation layer 4. A temperature control layer 6 is disposed on the bottom of the repair layer 5. An inner layer 7 is disposed on the bottom of the temperature control layer 6. The protective layer 1 is made of high-grammage kraft paper and double-sided PE film, and the thickness of the double-sided PE film is 0.03-0.0 mm. The shock-absorbing layer 2 is made of EPE pearl cotton, and the capsule layer 201 uses embedded microcapsules. The cardboard layer 3 is made of A-type corrugated base paper and bio-based polyurethane fiber combined material. The heat insulation layer 4 is made of aerogel felt material, and the repair layer 5 is made of polyurethane material containing microcapsules. The kraft paper fiber reinforced protective layer 1 has a tensile strength ≥8kN / m. The PE film blocks water vapor penetration and has no leakage after 48 hours at 90% humidity, achieving moisture protection. The EPE pearl cotton in the shock-absorbing layer 2 has a density of 25-30kg / m³ and a thickness of 3mm. The embedded microcapsules, with a particle size of 50-80μm and a proportion of 5%-8%, can absorb energy. The EPE closed-cell structure buffers impact force, with an energy absorption rate of ≥70% in drop tests. They also exhibit resistance to deformation, with a compression resilience of ≥90%. The A-type corrugated base paper in layer 3 has a basis weight of 120g / ㎡ and a flute height of 4.6mm. The bio-based polyurethane fiber incorporation ratio is 2%, providing good longitudinal compressive strength. The flute peak structure provides support, with an edge crush strength of ≥6kN / m and good toughness. The polyurethane fiber enhances bending resistance, increasing bending life by 3 times. The aerogel felt of the insulation layer is 2mm thick with a thermal conductivity of 0.018W / m·K. Its built-in aerogel blocks external temperatures. The repair layer 5 has a 0.05mm thick polyurethane coating on the microcapsules. The polyurethane coating enhances the interlayer bonding and peel strength ≥1.5N / mm. When the interlayer of repair layer 5 is peeled off, the microcapsules release the repair agent to repair the interface gaps. The peel strength recovery rate after repair is ≥70%, extending the service life. The temperature control layer 6 is a combination of paraffin-based phase change material and graphene thermal conductive film. The graphene thermal conductive film is 0.1mm thick with a thermal conductivity of 5300W / m·K, which has a temperature buffering effect. Graphene also quickly conducts local heat to avoid condensation. The inner layer 7 is a combination of PLA biodegradable film, 0.1mm thick, and light-responsive repair agent, which has anti-scratch and anti-static effects.

[0019] The implementation principle of a shock-absorbing cardboard board in this application embodiment is as follows: First, the protective layer 1 is composed of high-grammage kraft paper and double-sided PE film. The kraft paper fibers are interwoven to form a tensile structure, and the PE film physically blocks water vapor penetration. The shock-absorbing layer 2 uses EPE pearl cotton with a density of 25-30 kg / m³ and a thickness of 3 mm as the base material. Embedded microcapsules with a particle size of 50-80 μm are uniformly dispersed inside, accounting for 5%-8%, and the impact force is dispersed by the deformation of the closed-cell structure. The cardboard layer 3 is composed of A-type corrugated base paper with a basis weight of 120 g / m² and 2% bio-based polyurethane fiber, which is vertically supported by the corrugated peaks. In addition to fiber reinforcement to improve structural rigidity, the heat insulation layer 4 is composed of a 2mm thick aerogel felt, which slows down the heat transfer path through its nanoporous structure. The repair layer 5 has a 0.05mm thick polyurethane material containing microcapsules coated at the interlayer interface. After the microcapsules rupture, they release a repair agent to fill the interface gaps. The temperature control layer 6 is a paraffin-based phase change material PCM encapsulated in a 0.1mm thick graphene thermal conductive film. Thermal management is achieved through phase change heat absorption / release and graphene thermal conductivity. The inner layer 7 is composed of a 0.1mm thick PLA biodegradable film and a photoresponsive repair agent. The PLA molecular chains are reorganized and repaired through light / heat stimulation.
