Description

Technical Field

[0001] The utility model relates to the technical field of kraft paperboard, in particular to a high-strength anti-pollution kraft paperboard. Background Technique

[0002] Kraft paperboard is mainly made of wood pulp fibers, which are derived from the chemical treatment process of wood. Given the relative shortage of wood resources, in the raw material ratio for making kraft paperboard, in addition to using a certain proportion of wood pulp, various mixed pulps such as wheat straw pulp and rice straw pulp are also adopted. In recent years, with the improvement of environmental awareness and the rational utilization of resources, renewable resources such as bamboo pulp have gradually been introduced into the production of kraft paperboard, further promoting its sustainable development.

[0003] The production process of kraft paperboard is relatively complex, mainly including multiple links such as pulping and papermaking. And the entire production process requires strict control of various process parameters to ensure the stable quality of kraft paperboard. At the same time, kraft paperboard also has various excellent performance characteristics, such as toughness, good appearance quality, etc., making it widely used in multiple fields. With the continuous progress of technology and the improvement of environmental awareness, the production process of kraft paperboard will be continuously optimized and improved, and its application fields will also be further expanded.

[0004] However, currently when packaging items with kraft paperboard, the kraft paperboard may have its protection performance decreased due to pollution, abrasion or damage, reducing its service life, and thus unable to effectively guarantee the safety of the internal items. Content of the Utility Model

[0005] Based on this, the purpose of the utility model is to provide a high-strength anti-pollution kraft paperboard to solve the technical problem that when packaging items with kraft paperboard, the kraft paperboard may have its protection performance decreased due to pollution, abrasion or damage, reducing its service life, and thus unable to effectively guarantee the safety of the internal items.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A high-strength anti-pollution kraft paperboard, including a first support plate, a connecting plate and a second support plate. The connecting plate is located in the middle of the first support plate and the second support plate. The first support plate is located above the connecting plate, and the second support plate is located below the connecting plate. The connecting plate is set as a corrugated structure. Support blocks are arranged at the grooves of the connecting plate, and the support blocks are set as diamond structures. A group of card slots are arranged inside the support blocks, and a card block that fits with the card slots is connected in the middle of the group of card slots. Anti-pollution coatings are arranged on the surfaces of the first support plate and the second support plate.

[0007] By adopting the above technical solution, the connecting plate is set as a corrugated structure, which can effectively disperse and bear external forces, making the connecting plate more stable when subjected to pressure or impact, not easily deformed or damaged, thereby enhancing the load-bearing capacity and compressive performance of the entire cardboard. And a support block with a diamond structure is arranged in the groove of the corrugated structure, and a clamping block is connected in the support block, which can effectively disperse and bear the pressure from the connecting plate, the first support plate and the second support plate, so as to provide additional support, prevent local collapse or deformation, and enhance the overall stability and durability of the cardboard. At the same time, the anti-fouling coating can effectively resist the attachment and penetration of various stains. Therefore, the design of the kraft cardboard makes full use of the advantages of the corrugated structure and the diamond support block, combines the characteristics of the anti-fouling coating, extends the service life of the kraft cardboard, and can better protect items through the kraft cardboard, thereby improving the safety of the items.

[0008] The present utility model is further arranged such that the first support plate and the second support plate are arranged as long fiber pulp layers.

[0009] By adopting the above technical solution, the long fiber pulp layer can form a more compact and stable fiber network, enabling the cardboard to better disperse and bear pressure when subjected to external forces, thereby significantly enhancing the overall structural strength of the cardboard. At the same time, due to the good toughness of the long fibers and their resistance to breakage, it provides better tear resistance for the kraft cardboard and prevents the kraft cardboard from being damaged due to external forces during use.

[0010] The present utility model is further arranged such that the connecting plate is arranged as a multi-layer short fiber interwoven layer.

[0011] By adopting the above technical solution, the multi-layer short fiber interwoven layer forms a more compact and complex structural network through the interlacing and entanglement of the fibers, thereby enhancing the overall structural strength of the cardboard. At the same time, the short fibers have better flexibility and bending performance, making the kraft cardboard not easily break when subjected to impact or bending, increasing the folding resistance and durability of the cardboard. And the design of the multi-layer structure enables the connecting plate to resist and disperse the tearing energy layer by layer when subjected to tearing force, thereby improving the tear resistance of the cardboard.

[0012] The present utility model is further arranged such that the support block and the clamping block are arranged as composite materials.

[0013] By adopting the above technical solution, composite materials usually have higher strength and stiffness than single materials, enabling the support block and the clamping block to maintain a stable shape when bearing external forces, not easily deformed or broken, thereby enhancing the overall load-bearing capacity and structural stability of the cardboard.

[0014] The present utility model is further arranged such that the anti-fouling coating is a coating formed by mixing an anti-fouling agent, a waterproof agent and a strengthening agent.

[0015] By adopting the above technical solution, the coating formed by mixing the anti-fouling agent, waterproof agent and strengthening agent can form a more solid and durable protective layer, increasing the anti-fouling effect of the kraft paperboard, preventing moisture from penetrating into the interior of the paperboard and increasing the adhesion of the coating, thereby improving the overall service life and performance of the kraft paperboard.

[0016] The present utility model is further configured such that the first support plate, connecting plate, second support plate, support block and clamping block are connected by a high-strength adhesive.

[0017] By adopting the above technical solution, the high-strength adhesive can ensure the firm connection between the components such as the first support plate, connecting plate, second support plate, support block and clamping block, making the overall structure of the paperboard stable and capable of withstanding greater pressure and tensile force, thereby meeting the requirements of high strength and anti-fouling.

[0018] In summary, the present utility model mainly has the following beneficial effects:

[0019] By setting the connecting plate as a corrugated structure, the present utility model can effectively disperse and bear external forces, making the connecting plate more stable when subjected to pressure or impact, not easily deformed or damaged, thereby enhancing the load-bearing capacity and compressive performance of the entire paperboard. The design of the support block and clamping block can effectively disperse and bear the pressure from the connecting plate and the upper and lower support plates, providing additional support to prevent local collapse or deformation, enhancing the overall stability and durability of the paperboard. At the same time, the anti-fouling coating can effectively resist the adhesion and penetration of various stains. Therefore, the design of the kraft paperboard makes full use of the advantages of the corrugated structure and diamond-shaped support blocks, combines the characteristics of the anti-fouling coating, extends the service life of the kraft paperboard, and can better protect items through the kraft paperboard, thereby improving the safety of the items.

[0025] A high-strength anti-stain kraft paperboard, as Figure 1-2 shown, includes a first support plate 1, a connecting plate 2, and a second support plate 3. The connecting plate 2 is located in the middle of the first support plate 1 and the second support plate 3. The first support plate 1 is located above the connecting plate 2, and the second support plate 3 is located below the connecting plate 2. Then, a three-layer kraft paperboard can be formed by the first support plate 1, the connecting plate 2, and the second support plate 3 for use.

[0026] Subsequently, the connecting plate 2 is arranged in a corrugated structure, which can effectively disperse and bear external forces, enhancing the load-bearing capacity and compressive performance of the kraft paperboard. A support block 4 is arranged at the groove of the connecting plate 2, and the support block 4 is arranged in a diamond structure. A group of card slots 5 are arranged inside the support block 4, and a card block 6 that fits with the card slots 5 is connected in the middle of the group of card slots 5, which can effectively disperse and bear the pressure from the connecting plate 2, the first support plate 1, and the second support plate 3, thereby providing additional support to prevent local collapse or deformation, enhancing the overall stability and durability of the kraft paperboard. The four corners of the support block 4 are arranged in an arc shape, which is convenient for better connection with the connecting plate 2. At the same time, anti-stain coatings 8 are arranged on the surfaces of the first support plate 1 and the second support plate 3, and the anti-stain coatings 8 are composed of a mixture of anti-stain agents, waterproof agents, and strengthening agents, so that a more solid and durable protective layer can be formed, increasing the anti-stain effect of the kraft paperboard, preventing moisture from penetrating into the interior of the paperboard, and increasing the adhesion of the coating, thereby improving the overall service life and performance of the kraft paperboard. Then, the items can be better protected by the kraft paperboard, thereby improving the safety of the items.

[0027] Furthermore, the first support plate 1 and the second support plate 3 are arranged as long fiber pulp layers 7 to form a more compact and stable fiber network, enhancing the overall structural strength of the paperboard. And because the long fibers have good toughness and are not easily broken, it provides better tear resistance for the kraft paperboard, preventing the kraft paperboard from being damaged due to external forces during use; the connecting plate 2 is arranged as a multi-layer short fiber interweaving layer 9. Through the interlacing and entanglement between the fibers, the overall structural strength of the kraft paperboard is enhanced. At the same time, the short fibers have better flexibility and bending performance, which can increase the folding resistance and durability of the paperboard. And the design of the multi-layer structure enables the connecting plate 2 to resist and disperse the tearing energy layer by layer when subjected to tearing force, thereby improving the tear resistance of the kraft paperboard; the support block 4 and the card block 6 are arranged as composite materials 10, making them have higher strength and stiffness, so that the support block 4 and the card block 6 can maintain a stable shape when bearing external forces and are not easily deformed or broken, thereby enhancing the overall load-bearing capacity and structural stability of the paperboard.

[0028] In this embodiment, the first support plate 1, the connecting plate 2, the second support plate 3, the support block 4 and the clamping block 6 are connected by a high-strength adhesive, so that a firm connection can be formed between the first support plate 1, the connecting plate 2, the second support plate 3, the support block 4 and the clamping block 6, thereby increasing the overall structural stability of the kraft paperboard, enabling it to withstand greater pressure and tensile force, and thus meeting the requirements of high strength and anti-fouling.
