Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the utility model.

[0032] REFERENCE Figure 1 - Figure 3The utility model provides an embodiment: a kind of anti-deformation phenolic resin laminated paperboard, including press paperboard body 1, press paperboard body 1 inside is provided with buffer assembly, press paperboard body 1 side wall is provided with coating assembly;Buffer assembly includes foam layer 2, foam layer 2 is preliminarily buffered to external force under the premise of not increasing the overall weight of press paperboard body 1, foam layer 2 side wall is fixedly connected in press paperboard body 1 interior, foam layer 2 side wall is fixedly connected with rubber layer 3, rubber layer 3 side wall is fixedly connected with carbon fiber cloth 4, carbon fiber cloth 4 support rubber layer 3 on one side, on the other hand, part of external force is evenly dispersed to press paperboard body 1, carbon fiber cloth 4 side wall is fixedly connected in press paperboard body 1 interior, metal coating 5 is made of aluminium, for enhancing the overall rigidity of press paperboard body 1, rubber layer 3 is made of natural rubber by vulcanization process, for buffering effect is more comprehensive, carbon fiber cloth 4 is made of viscose base fiber, for improving the compression resistance of press paperboard body 1;

[0033] When press paperboard body 1 is impacted by external force, foam layer 2 deforms first due to its good buffering performance and low density characteristics, the buffering performance of foam layer 2 is derived from its internal microstructure, which can absorb energy by compression and deformation of internal pores when stressed, and the low density characteristics enable foam layer 2 to effectively preliminarily buffer external force without increasing the overall weight of press paperboard body 1, in the process of absorbing and dispersing part of the energy, foam layer 2 can adaptively adjust its deformation degree according to the size and direction of external force, thereby minimizing the direct impact of external force on press paperboard body 1, rubber layer 3 is connected to the side wall of foam layer 2 and has high elasticity and flexibility, the high elasticity enables rubber layer 3 to deform elastically to a large extent under the action of external force after the preliminary buffering of foam layer 2, and the flexibility of rubber layer 3 enables it to adapt to external forces in different directions, whether the external force is perpendicular, horizontal or oblique to press paperboard body 1, rubber layer 3 can effectively buffer and absorb energy by its deformation, making the buffering effect more comprehensive, carbon fiber cloth 4 is connected to the side wall of rubber layer 3 and fixed inside press paperboard body 1, carbon fiber cloth 4 supports rubber layer 3 on one side, as carbon fiber has extremely high strength, it can limit the excessive deformation of rubber layer 3 when rubber layer 3 is subjected to a large external force, preventing rubber layer 3 from losing its buffering effect due to excessive stretching or compression, on the other hand, carbon fiber cloth 4 itself plays a role when press paperboard body 1 is subjected to a large external force due to its high strength and high modulus characteristics, high strength means that carbon fiber cloth 4 can withstand a large tensile force and pressure without breaking, and high modulus makes it deform less when stressed, when press paperboard body 1 is subjected to a large external force, carbon fiber cloth 4 can evenly disperse part of the external force to the entire press paperboard body 1, avoiding excessive local stress, thereby improving the compression resistance of press paperboard body 1 and ensuring the stability of the buffer assembly.

[0034] ReferFigure 1 - Figure 3 The coating assembly includes a metal coating 5, the sidewall of which is fixedly connected to the sidewall of the pressing paper body 1, and a ceramic coating 6 is fixedly connected to the sidewall of the metal coating 5. Parallel stripes 7 are formed inside the pressing paper body 1. The metal coating 5 is made of aluminum and is used to enhance the overall rigidity of the pressing paper body 1, while also having good wear resistance and effectively resisting friction. The ceramic coating 6 is made of alumina and is used to improve the protective performance of the pressing paper body 1, further enhancing its protective performance. The parallel stripes 7 are made by a die pressing process and are used to disperse stress, improve the compressive strength of the pressing paper, reduce the possibility of local damage to the pressing paper body 1 due to stress concentration, and increase the internal surface area of ​​the pressing paper body 1, thereby enhancing the internal structural strength of the pressing paper body 1.

[0035] The sidewall of the pressing board body 1 is provided with a coating assembly, which includes a metal coating 5 and a ceramic coating 6. Parallel stripes 7 are formed on the surface of the pressing board body 1. The metal coating 5 has good strength and toughness and is connected to the sidewall of the pressing board body 1. Its strength characteristics allow the metal coating 5 to provide additional strength support for the pressing board body 1. When the pressing board body 1 is subjected to various external forces, the metal coating 5, with its own strength, shares some of the pressure, enabling the pressing board body 1 to withstand a greater load and preventing deformation. Simultaneously, the metal coating 5 has good wear resistance; when external objects rub against the surface of the pressing board body 1... The metal coating 5 effectively resists this friction, reducing external frictional damage to the surface of the pressing board body 1, thereby extending the service life of the pressing board body 1. The ceramic coating 6 has high hardness, high temperature resistance, and good chemical stability. It is connected to the side wall of the metal coating 5. The high hardness of the ceramic coating 6 allows it to effectively disperse and resist external forces when faced with large external forces. When the pressing board body 1 is subjected to a strong impact, the ceramic coating 6 first bears most of the pressure, dispersing the external force to a larger area through its own hardness, thereby reducing the local pressure acting on the metal coating 5 and the pressing board body 1. At the same time, its high temperature resistance makes the pressing board body 1 more durable. The board body 1 maintains good performance even in high-temperature environments. In some high-temperature operating scenarios, the ceramic coating 6 can prevent high temperatures from damaging the metal coating 5 and the pressing board body 1, ensuring that the pressing board body 1 can still work normally under high-temperature conditions. In addition, the good chemical stability of the ceramic coating 6 enables it to resist the corrosion of various chemicals. In some environments where it may come into contact with chemicals, the ceramic coating 6 can protect the metal coating 5 and the pressing board body 1 from chemical corrosion, maintaining the structural integrity and performance stability of the pressing board body 1. At the same time, the parallel stripes 7 inside the pressing board body 1 play a role when under pressure. When the pressing board body 1 is under pressure, these parallel stripes 7 can disperse stress by changing the internal structural morphology of the pressing board body 1. The presence of parallel stripes 7 breaks the original uniform structure inside the pressing board body 1, so that the pressure is no longer concentrated at a certain point or area during transmission, but is dispersed and transmitted along the direction of the parallel stripes 7. This dispersion effect avoids the occurrence of stress concentration, effectively reducing the possibility of local damage to the pressing board body 1 due to stress concentration. At the same time, the parallel stripes 7 increase the internal surface area of ​​the pressing board body 1, which to a certain extent enhances the internal structural strength of the pressing board body 1.

[0036] Working principle: When the pressure plate body 1 is impacted by an external force, the foam layer 2 deforms first due to its cushioning performance and low density characteristics. It absorbs and disperses some of the energy through its compressibility, playing a preliminary cushioning role and reducing the overall weight. The rubber layer 3 is connected to the side wall of the foam layer 2 and has high elasticity and flexibility. After the initial cushioning by the foam layer 2, the rubber layer 3 undergoes greater elastic deformation due to its high elasticity, further absorbing the impact energy. Its flexibility can adapt to external forces in different directions, making the cushioning more comprehensive. The carbon fiber cloth 4 is connected to the side wall of the rubber layer 3 and fixed inside the pressure plate body 1. On the one hand, it supports the rubber layer 3 to prevent it from deforming due to excessive force and losing its cushioning effect. On the other hand, due to its high strength and high modulus characteristics, it disperses some of the force to the entire pressure plate body 1 when it is subjected to a large external force, improving the compressive strength and ensuring the stability of the cushioning component.

[0037] The sidewall of the pressing board body 1 is provided with a coating assembly, including a metal coating 5 and a ceramic coating 6, and parallel stripes 7 are formed on the surface of the pressing board body 1. The metal coating 5 has strength and toughness, and is connected to the sidewall of the pressing board body 1, which can provide additional strength support for the pressing board body 1, while also having wear resistance, reducing external friction damage to the surface of the pressing board body 1. The ceramic coating 6 has high hardness, high temperature resistance and good chemical stability, and is connected to the sidewall of the metal coating 5. When the pressing board body 1 is subjected to a large external force, it can effectively disperse and resist the external force, reducing the pressure and wear on the metal coating 5 and the pressing board body 1. At the same time, the parallel stripes 7 inside the pressing board body 1 can disperse stress when under pressure, and by changing the internal structural shape, avoid stress concentration, so that the external force can be transmitted and dispersed more evenly.
