Description

Technical Field

[0001] The utility model belongs to the technical field of corrugated paper, in particular to a novel high-strength corrugated paperboard. Background Art

[0002] Corrugated paper is currently widely used in paper packaging. It has many advantages such as simple processing, light weight, high strength and hardness, and easy storage. It is becoming more and more popular among packaging companies and is widely used in the market for the packaging, storage and transportation of food or digital products.

[0003] In order to prevent liquid from soaking and affecting its own strength, high-strength corrugated cardboard has a layer of waterproof film attached to its surface. However, when blunt or sharp objects from the outside come into friction contact with it, the waterproof film on the outside of the cardboard will be scratched, and the cardboard itself will be concave and deformed. Liquid will penetrate and erode it through the scratched opening, which will cause large-scale detachment and delamination of the waterproof film, and subsequent concave deformation will affect its overall compression properties.

[0004] Therefore, it is very necessary to invent a new type of high-strength corrugated paperboard. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a new type of high-strength corrugated paperboard, including a corrugated paper substrate and a waterproof armor, wherein the corrugated paper substrate and the waterproof armor are compositely bonded together, and the waterproof armor is arranged on the outside of the corrugated paper substrate;

[0006] The waterproof armor comprises a buffer cardboard layer, a waterproof film, an armor mesh layer and an anti-collision rubber layer. The buffer cardboard layer is compositely bonded to a corrugated paper substrate, the buffer cardboard layer is composited with a waterproof film, the waterproof film is composited with an armor mesh layer, and the armor mesh layer is composited with an anti-collision rubber layer.

[0007] Preferably, the corrugated paper substrate comprises a corrugated core, an outer paperboard layer and an inner paperboard layer, the corrugated core is composited with the outer paperboard layer and the inner paperboard layer respectively, and the inner paperboard layer is composited with a buffer paperboard layer.

[0008] Preferably, the buffer paperboard layer is provided with grooves that match the armor mesh layer, and the surface of the buffer paperboard layer with the grooves is compounded with a waterproof film, which is a waterproof film made of polymer material.

[0009] Preferably, the armor mesh layer is a mesh body woven with metal wires, and the armor mesh layer is compounded in the grooves of the buffer paperboard layer and protrudes outward.

[0010] Preferably, the anti-collision rubber layer is made of silicone, and is provided with grooves that fit with the armor mesh layer. The anti-collision rubber layer wraps the protruding part of the armor mesh layer, and the armor mesh layer is composited between the buffer cardboard layer and the anti-collision rubber layer.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model discloses a corrugated paper substrate having a waterproof armor arranged on its outside, which is made of polymer materials and metal materials. The reference design of the modified materials can reduce the overall thickness while improving the overall strength of the paperboard. In addition, when blunt or sharp objects from the outside are scratched or contacted with the corrugated paper substrate, the waterproof armor can effectively protect the inner corrugated paper substrate to avoid damage to the corrugated paper substrate as a whole. Secondly, because the waterproof film of the waterproof armor is arranged on its inner side, scratches on the waterproof film can be avoided, and the waterproof property itself is extremely strong.

[0019] As attached Figure 1 To Attachment Figure 3 As shown:

[0020] The utility model provides a novel high-strength corrugated paperboard, comprising a corrugated paper substrate 1 and a waterproof armor 2, wherein the corrugated paper substrate 1 and the waterproof armor 2 are compositely bonded together, the waterproof armor 2 is arranged on the outside of the corrugated paper substrate 1, and the corrugated paper substrate 1 is a base layer of the corrugated paperboard.

[0021] The waterproof armor 2 includes a buffer cardboard layer 21, a waterproof membrane 22, an armor mesh layer 23 and an anti-collision rubber layer 24. The buffer cardboard layer 21 is compositely bonded with the corrugated paper substrate 1, the buffer cardboard layer 21 is composited with a waterproof membrane 22, the waterproof membrane 22 is composited with the armor mesh layer 23, the armor mesh layer 23 is composited with an anti-collision rubber layer 24, and the waterproof armor 2 is an armor layer of corrugated cardboard. Embodiment 1:

[0022] Specifically, the corrugated paper substrate 1 includes a corrugated core 11, an outer paperboard 12 and an inner paperboard 13. The corrugated core 11 is composited with the outer paperboard 12 and the inner paperboard 13 respectively. The inner paperboard 13 is composited with a buffer paperboard layer 21. The buffer paperboard layer 21 is a honeycomb paperboard.

[0023] Specifically, the buffer paperboard layer 21 is provided with grooves that fit with the armor mesh layer 23. The surface of the buffer paperboard layer 21 with grooves is compounded with a waterproof membrane 22. The waterproof membrane 22 is a waterproof film made of polymer material. The armor mesh layer 23 presses the waterproof membrane 22 into the grooves of the buffer paperboard layer 21.

[0024] Specifically, the armor mesh layer 23 is a mesh body woven with metal wires. The armor mesh layer 23 is compounded in the grooves of the buffer paperboard layer 21 and protrudes outward. The waterproof membrane 22 and the armor mesh layer 23 are arranged between the buffer paperboard layer 21 and the anti-collision rubber layer 24.

[0025] Specifically, the anti-collision rubber layer 24 is a rubber layer made of silicone. The anti-collision rubber layer 24 is provided with grooves that fit with the armor mesh layer 23. The anti-collision rubber layer 24 wraps the protruding part of the armor mesh layer 23. The armor mesh layer 23 is compounded between the buffer cardboard layer 21 and the anti-collision rubber layer 24. While the buffer cardboard layer 21 and the anti-collision rubber layer 24 are compounded with the armor mesh layer 23, the two are also bonded to each other. Embodiment 2:

[0026] When a blunt object from the outside scrapes against the corrugated cardboard, the anti-collision rubber layer 24 of the waterproof armor 2 will give priority to protecting it. The anti-collision rubber layer 24 and the armor mesh layer 23 can prevent large-area concave deformation after the blunt object scrapes against the corrugated cardboard. When a sharp object scrapes against the corrugated cardboard, the anti-collision rubber layer 24 gives priority to protecting the inner base layer. However, when the sharp object passes through the anti-collision rubber layer 24, the armor mesh layer 23 on the inside will block the sharp object to prevent the sharp object from scratching the inner base layer. After the subsequent liquid enters the interior through the gap scratched by the sharp object, the waterproof membrane 22 will block the further penetration of the liquid. In addition, because the materials used for the armor mesh layer 23 and the anti-collision rubber layer 24 will not be affected by the erosion of the liquid and affect its strength, it can effectively prevent the overall strength from being seriously affected after being damaged.

[0027] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
