[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1 , 2As shown in Figures , 3, 4, 5 and 6, the utility model provides a technical solution: a high-strength vertical corrugated paperboard, comprising: an outer paper 1 and an inner paper 2, the outer sides of the outer paper 1 and the inner paper 2 are provided with a reinforcing layer, and the inner paper 2 is placed under the outer paper 1; the corrugated medium is bonded between the outer paper 1 and the inner paper 2 by an adhesive, and the adhesive is a starch-based or synthetic resin adhesive to ensure a close bond between the layers, the corrugated medium comprises a No. 1 support member 3 and a No. 2 support member 4, the middle part of the No. 1 support member 3 is bonded with a vertical wavy connecting ridge 6 of the outer paper 1, and the middle part of the No. 2 support member 4 is bonded with a plurality of support bodies 8, which are used to improve the strength of the vertical corrugated paperboard.

[0025] It should be noted that the outer paper 1 and the inner paper 2 of the utility model are made of high-quality kraft paper with good tensile and rupture resistance. The No. 1 support member 3 can greatly enhance the vertical compression strength of the cardboard because of the supporting effect of the vertical corrugations against pressure. Multiple support bodies are bonded to the middle part of the No. 2 support member, and the support body adopts a block design with a solid structure, which further enhances the overall strength.

[0026] See also Figure 2 , 3 As shown, support member No. 1 3 and support member No. 2 4 are alternately arranged, and multiple support members No. 1 3 are bonded between two adjacent support members No. 2 4 . Support member No. 1 3 also includes two vertical ribs 5 , which are perpendicularly arranged to the outer paper 1 , and a connecting rib 6 is placed between the two vertical ribs 5 .

[0027] It should be noted that the utility model can achieve a more uniform force distribution by staggering the No. 1 support member 3 and the No. 2 support member 4. The staggered arrangement helps to balance the bearing capacity within the entire area of ​​the cardboard, so that the pressure can be better dispersed when it is under pressure, avoiding damage caused by concentrated load. Multiple No. 1 support members 3 are bonded between two adjacent No. 2 support members 4, which further increases the structural density and support points of the cardboard and improves the cardboard's ability to resist deformation when subjected to external forces. The No. 1 support member 3 includes two vertical ribs 5, which are arranged perpendicular to the outer paper 1. The arrangement of the vertical ribs 5 enhances the vertical compression strength of the cardboard because they can effectively support the cardboard against pressure in the vertical direction. The connecting rib 6 is placed between the two vertical ribs 5. The connection not only provides additional structural support, but also helps maintain the position and spacing of the vertical ribs, ensuring their stability and efficiency when bearing loads.

[0028] See also Figure 5 , 6 As shown, the second support member 4 also includes two upper and lower support cardboards 7 , the support cardboards 7 are arranged parallel to the outer paper 1 , and a plurality of support bodies 8 are fixedly connected between the two support cardboards 7 .

[0029] It should be noted that, in the present invention, multiple support bodies 8 are fixedly connected between two supporting cardboards 7. The support bodies can be structures of various shapes and materials. Their main function is to increase the spacing between the supporting cardboards 7 and provide additional support when the cardboards are under pressure, which can effectively enhance the vertical bearing capacity of the cardboards and enable them to better cope with external forces in the vertical direction.

[0030] See also Figure 6 As shown, the multiple support bodies 8 are isosceles trapezoidal structures, and the two bottom sides of the isosceles trapezoidal structures are respectively fixed to the corresponding support paperboards 7, and two adjacent support bodies 8 are arranged upside down.

[0031] It should be noted that the waist trapezoidal structure of the utility model has two opposite oblique sides and two different bottom sides, and this shape provides additional stability in the structure; when applied to the support body, the wider bottom side can be fixed on the support cardboard to provide a larger contact area, thereby enhancing the firmness of the fixation and the overall bearing capacity; the two bottom sides of each waist trapezoid are respectively fixed to the corresponding support cardboard 7, one bottom side of the trapezoid is connected to the upper support cardboard, and the other bottom side is connected to the lower support cardboard; this fixing method not only increases the contact area, but also enhances the stable supporting effect of the trapezoid through the distribution of the bottom sides; the two adjacent support bodies 8 are set upside down, the wide bottom of one trapezoid is located at the top, and the wide bottom of the other adjacent trapezoid is located at the bottom; this staggered arrangement can effectively disperse and balance the force generated by the pressure of the heavy objects above, so that the entire support system is more uniform and stable when subjected to force.

[0032] See also Figure 1 As shown, the reinforcement layer is made of cellulose nanocrystals.

[0033] It should be noted that the reinforcing layer of the utility model is a CNC coating, and the CNC coating is cellulose nanocrystals. Cellulose nanocrystals are nano-scale materials extracted from natural wood or plant fibers, which can significantly improve the mechanical properties of paper. By applying the CNC coating on the surface of the cardboard, its stiffness and tensile strength can be increased, making the cardboard stronger.
