TECHNICAL FIELD

[0001] The utility model relates to paperboard technical field, concretely is a kind of high-strength paperboard. BACKGROUND

[0002] Paperboard is a kind of thick sheet material which is processed by pulp as main raw material through multiple processes. It is usually made of multiple layers of paper or paperboard, and has high stiffness, strength and cushioning performance. Paperboard is widely used in packaging, printing, making paper boxes, cartons and other fields, which can provide protection for goods, facilitate transportation and storage, and is also commonly used to make display stands, folders and other daily necessities. It is an indispensable basic material in industrial production and daily life.

[0003] The compressive resistance of traditional paperboard is poor. When used to package heavy objects, the paperboard is easily deformed or even damaged under the action of external forces such as extrusion and collision during transportation, which cannot effectively protect the internal objects, increasing the risk of damage to the objects. Therefore, in order to ensure a certain strength, the thickness or number of layers of the paperboard often needs to be increased, resulting in a larger weight of the paperboard. This not only increases the packaging cost, but also consumes more energy during transportation, which does not meet the current energy-saving and environmental protection development trend. SUMMARY

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0025] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0026] Please see Figures 1-4 This utility model provides a high-strength cardboard, comprising a bottom cardboard 1, a top cardboard 6, and a corrugated cardboard 8. A first dividing beam 2 is provided on the upper surface of the bottom cardboard 1, and multiple lower corrugated paper layers 3 with a rectangular structure are disposed inside the first dividing beam 2. A second dividing beam 4 is provided on the upper side of the first dividing beam 2, and multiple upper corrugated paper layers 5 with a triangular structure are disposed inside the second dividing beam 4. Both the lower corrugated paper layers 3 and the upper corrugated paper layers 5 are formed by folding and splicing the corrugated cardboard 8. The top cardboard 6 is disposed on the upper surface of the second dividing beam 4.

[0027] First, glue the first dividing paper beam 2 onto the surface of the bottom paperboard 1. Fold and splice the corrugated cardboard 8 into a rectangular structure and glue it inside the first dividing paper beam 2. Then, glue the second dividing paper beam 4 on top of the first dividing paper beam 2. Fold and splice the corrugated cardboard 8 into corresponding triangles and glue them inside the second dividing paper beam 4. Finally, glue the top paperboard 6 onto the second dividing paper beam 4. After the glue dries and cures, an integrated structure is formed.

[0028] By folding and splicing the corrugated cardboard 8 into a lower corrugated layer 3 and an upper corrugated layer 5, the lower corrugated layer 3 and the upper corrugated layer 5 intersect at different angles and have different textures. This avoids the cardboard bending along the texture and increases the elasticity and deformation capacity of the cardboard in multiple directions. Therefore, it improves the cardboard's compression resistance, cushioning, lightweighting and stability. It is especially suitable for applications that require high-strength packaging, such as heavy transport boxes or special scenarios such as building partitions and furniture shelves.

[0029] Please see Figures 4-5 Fold the corrugated cardboard 8 along the diagonal to form a small triangular structure;

[0030] Please see Figures 6-7 By gluing together two or four folded small triangular structures, a large triangular structure and a rectangular structure can be formed. The large and small triangular structures are the upper corrugated paper layer 5, which is placed inside the second dividing paper beam 4, and the rectangular structure is the lower corrugated paper layer 3, which is placed inside the first dividing paper beam 2.

[0031] Preferably, an adhesive layer 7 is provided between the lower corrugated paper layer 3 and the upper corrugated paper layer 5.

[0032] Because the opposing surfaces of the lower corrugated paper layer 3 and the upper corrugated paper layer 5 have textures, the bonding area is small, which can easily lead to poor adhesion. Therefore, by setting the adhesive layer 7, both the lower corrugated paper layer 3 and the upper corrugated paper layer 5 can be tightly bonded to the adhesive layer 7, thereby improving the bonding strength.

[0033] Preferably, the interior of both the first dividing paper beam 2 and the second dividing paper beam 4 is a hollow structure.

[0034] The hollow structure deforms when impacted, thus acting as a buffer.

[0035] Preferably, both the first dividing paper beam 2 and the second dividing paper beam 4 are provided with cross-shaped reinforcing plates 9 inside.

[0036] The cross-shaped reinforcing plate 9 provides certain support for the interior of both the first and second paper beams 2 and 4, making them less prone to deformation while having a buffering effect, thus improving their performance.

[0037] Preferably, both the outer surfaces of the bottom paperboard 1 and the top paperboard 6 are provided with a waterproof layer, which is a PE plastic film.

[0038] The waterproof layer effectively prevents external moisture from entering, ensuring that the quality and performance of the contents are not affected, and preventing the cardboard from getting damp, which would reduce its strength and extend its service life.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
