Description

Technical Field

[0001] This utility model relates to the field of paperboard technology, and in particular to a high-strength environmentally friendly paperboard. Background Technology

[0002] There are many types of cardboard, including corrugated cardboard. Corrugated cardboard is a lightweight board made of multiple layers of paper bonded together by a special process. Its core feature is the corrugated core in the middle. This design makes it lightweight while having excellent compression resistance, cushioning and load-bearing capacity, making it one of the most widely used materials in the modern packaging industry.

[0003] In practical use, existing corrugated cardboard is prone to collapse under excessive loads due to the shape of the corrugated core paper. Furthermore, relying solely on starch adhesive as a connecting structure provides insufficient bonding strength and water resistance, thereby reducing the overall structural strength of the corrugated cardboard. Therefore, a high-strength, environmentally friendly cardboard is needed. This cardboard design incorporates additional support columns to increase the compressive strength of the corrugated core paper. Additionally, the addition of nano-additives not only enhances the adhesion of the adhesive layer but also improves its water resistance. Utility Model Content

[0004] The purpose of this utility model is to provide a high-strength environmentally friendly paperboard to solve the problem mentioned in the background art that, in actual use, the corrugated core paperboard collapses under excessive load due to the shape of the corrugated core paperboard, and the adhesive strength and water resistance are insufficient when relying solely on starch glue as a connecting structure, thus reducing the overall structural strength of the corrugated paperboard.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a high-strength, environmentally friendly cardboard, comprising:

[0007] Corrugated cardboard body and protective components located at both ends of the corrugated cardboard body;

[0008] The main body of the corrugated cardboard includes a face paper, an adhesive layer, a corrugated core paper, a liner paper, and support columns. The adhesive layer is located between the face paper and the top of the corrugated core paper, and between the liner paper and the bottom of the corrugated core paper. The adhesive layer is composed of a mixture of starch glue and nano-additives. The support columns are fixed between the liner paper and the corrugated core paper, and the support columns are evenly distributed.

[0009] Furthermore, the outer surface of the face paper and the inner paper is coated with a moisture-proof layer, which is composed of paraffin wax.

[0010] Furthermore, the protective component includes a protective frame, a support block, a limiting plate, and a connecting post; the protective frame is wrapped around the outside of both ends of the corrugated cardboard body, and two sets of protective frames are provided. The support block is fixed inside the two sides of the protective frame, the limiting plate is attached to the outer surface of one end of the protective frame, and the connecting post is fixed to the outer surface of the limiting plate and is connected through the inside of the protective frame.

[0011] Furthermore, a fixing post is fixed to the outer surface of both sides of the protective frame at the other end, a spring is fixed inside the fixing post, and a movable block is fixed to the outer surface of the spring.

[0012] Furthermore, a first connecting rod is fixed to the outer surface of the movable block, and the first connecting rod passes through and is connected to the interior of the connecting column. A second connecting rod is fixed to the inner surface of the movable block, and the second connecting rod passes through and is connected to the interior of the fixed column.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] I. This utility model increases the compressive strength of the corrugated core paper through the design of additional support columns, and improves the water resistance of the adhesive layer by adding nano-additives. This solution not only improves the overall stability and deformation resistance of the corrugated cardboard body, but also enables the corrugated cardboard body to maintain good structural integrity in humid environments. Furthermore, the starch adhesive design ensures the environmental friendliness of the corrugated cardboard body.

[0015] II. Based on the first beneficial effect, when the corrugated cardboard body needs to be transported to the required location with the cooperation of the protective components, firstly, the protective frame is placed over the outside of the corrugated cardboard body, then the connecting post is inserted into the inside of the protective frame. Subsequently, a pulling force is applied to the second connecting rod, and the movable block drives the second connecting rod to move towards the fixed post, applying a pushing force to the limiting plate, so that the connecting post passes through the inside of the other end of the protective frame, and the limiting plate is in contact with the surface of one end of the protective frame. The force applied to the second connecting rod is then removed, and under the elastic force of the spring, the first connecting rod springs into the inside of the connecting post.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Please see Figures 1-4 As shown, this embodiment is a high-strength environmentally friendly paperboard, comprising:

[0028] Corrugated cardboard body 1 and protective components located at both ends of corrugated cardboard body 1;

[0029] The corrugated cardboard body 1 includes a face paper 11, an adhesive layer 12, a corrugated core paper 13, a liner paper 14, and support columns 16. The adhesive layer 12 is located between the face paper 11 and the top of the corrugated core paper 13, and the adhesive layer 12 is located between the liner paper 14 and the bottom of the corrugated core paper 13. The adhesive layer 12 is composed of a mixture of starch glue and nano additives. The support columns 16 are fixed between the liner paper 14 and the corrugated core paper 13, and the support columns 16 are evenly distributed.

[0030] The face paper 11 is located on the outermost layer of the corrugated cardboard, mainly serving a protective and decorative function, while also preventing external factors from damaging the internal structure to a certain extent. The adhesive layer 12 is composed of a mixture of starch glue and nano-additives, and its function is to firmly bond the face paper 11, the inner paper 14, and the corrugated core paper 13 together to form a stable corrugated cardboard structure. The corrugated core paper 13 is the main supporting structure of the corrugated cardboard, providing cushioning and compression resistance through its special corrugated shape. The inner paper 14 is located on the inner layer of the corrugated cardboard, and together with the face paper 11, it provides protection and support for the corrugated core paper 13. The support column 16 is used to increase the compression resistance of the corrugated core paper 13.

[0031] The outer surfaces of the face paper 11 and the inner paper 14 are coated with a moisture-proof layer 15, which is composed of paraffin wax.

[0032] The moisture barrier 15 is used to improve the waterproof performance of corrugated cardboard. Paraffin wax has a melting point of about 40-60℃ and has good waterproof and sealing properties. It can form a uniform waterproof layer on the paper surface to prevent the intrusion of external moisture.

[0033] Working principle: The design of additional support columns 16 increases the compressive strength of the corrugated core paper 13, and the addition of nano-additives not only increases the adhesion of the adhesive layer 12, but also improves the water resistance of the adhesive layer 12.

[0034] This solution not only improves the overall stability and deformation resistance of the corrugated cardboard body 1, but also ensures that the corrugated cardboard body 1 maintains good structural integrity in a humid environment. Furthermore, the starch adhesive design ensures the environmental friendliness of the corrugated cardboard body 1.

[0035] Please see Figures 1-3 As shown, this embodiment, based on the above embodiment, further includes a protective component, which includes a protective frame 21, a support block 22, a limiting plate 23, and a connecting post 24. The protective frame 21 is wrapped around the outside of both ends of the corrugated cardboard body 1. There are two sets of protective frames 21. The support block 22 is fixed inside both sides of the protective frame 21. The limiting plate 23 is attached to the outer surface of one end of the protective frame 21. The connecting post 24 is fixed to the outer surface of the limiting plate 23 and is connected through the inside of the protective frame 21.

[0036] The main function of the protective frame 21 is to protect the edges and corners of the corrugated cardboard body 1 during transportation, preventing the edges and corners from collapsing or being damaged due to collisions or squeezing. The support block 22 is used to enhance the structural stability of the protective frame 21. The limiting plate 23 is used to restrict the connecting column 24 inside the two sets of protective frames 21. The connecting column 24 is used to connect the two sets of protective frames 21 together.

[0037] On the other end, the outer surfaces of both sides of the protective frame 21 are fixed with fixing posts 25, the inside of the fixing posts 25 is fixed with springs 26, and the outer surface of the springs 26 is fixed with movable blocks 27.

[0038] The fixed column 25 is used to support and install the spring 26. The spring 26 provides elastic force to the movable block 27. When the movable block 27 is not affected by external force, the first connecting rod 28 can quickly spring back to the desired position. The movable block 27 is used to support and install the first connecting rod 28, and then support and install the second connecting rod 29.

[0039] A first connecting rod 28 is fixed to the outer surface of the movable block 27, and the first connecting rod 28 passes through and connects to the inside of the connecting post 24. A second connecting rod 29 is fixed to the inner surface of the movable block 27, and the second connecting rod 29 passes through and connects to the inside of the fixed post 25.

[0040] The first connecting rod 28 is used to restrict and fix the connecting post 24 inside the two sets of protective frames 21, while the second connecting rod 29 facilitates the application of pulling force to the movable block 27.

[0041] Working principle: When the corrugated cardboard body 1 needs to be transported to the required position, firstly, the protective frame 21 is placed on the outside of the corrugated cardboard body 1, then the connecting post 24 is inserted into the inside of the protective frame 21. Subsequently, a pulling force is applied to the second connecting rod 29, and the movable block 27 drives the second connecting rod 29 to move towards the fixed post 25, applying a pushing force to the limiting plate 23, so that the connecting post 24 passes through the inside of the other end of the protective frame 21, and the limiting plate 23 is in contact with the surface of one end of the protective frame 21. The force applied to the second connecting rod 29 is removed, and under the elastic force of the spring 26, the first connecting rod 28 springs into the inside of the connecting post 24.

[0042] This step effectively protects the edges and corners of the corrugated cardboard body 1, preventing the edges and corners from collapsing during transportation.
