Description

Technical Field

[0001] This utility model belongs to the field of corrugated cardboard technology, and specifically relates to a corrugated cardboard. Background Technology

[0002] Corrugated cardboard is a multi-layered adhesive, mainly composed of a corrugated core paper layer (commonly known as "corrugated sheet", "corrugated paper", "corrugated core", "corrugated base paper") and a cardboard layer (also known as "boxboard"). This structure gives corrugated cardboard high mechanical strength, enabling it to effectively resist collisions and drops during handling.

[0003] In the existing technology, corrugated cardboard is usually composed of face paper, corrugated paper and core paper. After being processed by special technology, it forms a board with strong toughness and elasticity. The corrugations of the corrugated cardboard are like a series of connected arches, arranged in a row to form a triangular structure. It has good mechanical strength and elasticity, can withstand a certain amount of pressure, and has a good cushioning effect.

[0004] In the process of achieving the above, the inventors discovered that the technology has at least the following problems: Although the existing corrugated cardboard has achieved a good cushioning effect, because corrugated cardboard usually has a multi-layer structure and a lot of space inside, when used in a low humidity environment, the moisture in the environment can easily enter and remain inside the corrugated cardboard, causing the inside of the corrugated cardboard to become damp and moldy, or even rot, affecting the structure and life of the corrugated cardboard. Utility Model Content

[0005] The purpose of this utility model is to provide a corrugated cardboard to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a corrugated cardboard, comprising a flat board, a corrugated board, and moisture-proof rods. There are two flat boards, and the corrugated board is fixedly connected between the two flat boards. There are several moisture-proof rods, evenly distributed on both sides of the corrugated board, and the moisture-proof rods are adhered to the corrugated recesses of the corrugated board. The moisture-proof rods have a mesh structure, and their interiors are filled with a desiccant. The flat board includes a board base layer, and a moisture-proof membrane is fixedly connected to the outer surface of the board base layer. A waterproof membrane is fixedly connected to the outer surface of the moisture-proof membrane, and a wear-resistant layer is fixedly connected to the outer surface of the waterproof membrane. An anti-mildew layer is fixedly connected to the inner surface of the board base layer.

[0007] In a preferred embodiment, the moisture-proof film is a high-density polyethylene film.

[0008] In a preferred embodiment, the waterproof membrane is a polytetrafluoroethylene film.

[0009] In a preferred embodiment, the wear-resistant layer is a polyamide fiber woven layer.

[0010] In a preferred embodiment, the anti-mildew layer is a bamboo charcoal fiber woven layer.

[0011] In a preferred embodiment, both the planar plate and the corrugated plate are provided with a nano-silver ion antibacterial coating on the side that is close to each other.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This corrugated cardboard, by incorporating a moisture-proof membrane and a waterproof membrane, enhances its waterproof and moisture-proof performance when used in low-humidity environments. It prevents external moisture from entering the interior of the corrugated cardboard, thereby reducing the amount of moisture that can penetrate inside. Furthermore, by installing moisture-proof rods within the corrugated board's corrugated recesses, if moisture does enter the interior of the corrugated cardboard, the desiccant inside the rods can absorb the moisture, keeping the interior of the corrugated cardboard dry. This prevents the interior of the corrugated cardboard from becoming damp, thus protecting its structure and lifespan.

[0014] This corrugated cardboard, by setting a nano silver ion antibacterial coating, can prevent bacteria from growing on the surface of the flat and corrugated boards when moisture enters the interior of the corrugated cardboard, thereby avoiding mold growth caused by bacteria and preventing internal rot of the corrugated cardboard. By setting an anti-mold layer, it can prevent mold from growing inside the flat boards, thereby reducing the occurrence of corrugated cardboard rot. Attached Figure Description

[0019] The present invention will be further described below with reference to the embodiments.

[0020] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0021] Please see Figure 1-3 This utility model provides a corrugated cardboard, including a flat board 1, a corrugated board 2, and moisture-proof rods 3. There are two flat boards 1, and the corrugated board 2 is fixedly connected between the two flat boards 1. There are several moisture-proof rods 3, which are evenly distributed on both sides of the corrugated board 2 and are adhered to the corrugated recesses of the corrugated board 2. The moisture-proof rods 3 have a mesh structure and are filled with desiccant 31. By setting the moisture-proof rods 3 in the corrugated recesses of the corrugated board 2, when the corrugated cardboard is used in a low-humidity environment, if moisture enters the interior of the corrugated cardboard, the desiccant 31 in the moisture-proof rods 3 can absorb the moisture that has entered the interior of the corrugated cardboard, keeping the interior of the corrugated cardboard dry. This can prevent the interior of the corrugated cardboard from getting damp and ensure the structure and lifespan of the corrugated cardboard.

[0022] Reference Figure 1 Both the flat board 1 and the corrugated board 2 have a nano silver ion antibacterial coating 4 on their adjacent sides. By setting the nano silver ion antibacterial coating 4, when moisture enters the interior of the corrugated cardboard, the nano silver ion antibacterial coating 4 can prevent bacteria from growing on the surface of the flat board 1 and the corrugated board 2, thereby avoiding mold caused by bacteria and preventing the interior of the corrugated cardboard from rotting.

[0023] Reference Figure 3 The flat board 1 includes a board base layer 11. A moisture-proof membrane 12 is fixedly connected to the outer surface of the board base layer 11. The moisture-proof membrane 12 is a high-density polyethylene film. A waterproof membrane 13 is fixedly connected to the outer surface of the moisture-proof membrane 12. The waterproof membrane 13 is a polytetrafluoroethylene film. By setting the moisture-proof membrane 12 and the waterproof membrane 13, the waterproof and moisture-proof performance of the corrugated cardboard can be improved, and external moisture can be prevented from entering the interior of the corrugated cardboard, thereby reducing the amount of moisture entering the interior of the corrugated cardboard.

[0024] Reference Figure 3 A wear-resistant layer 14 is fixedly connected to the outer surface of the waterproof membrane 13. The wear-resistant layer 14 is a polyamide fiber woven layer. By setting the wear-resistant layer 14, the wear resistance of the corrugated cardboard surface can be improved, making the corrugated cardboard less prone to wear, thereby protecting the moisture-proof membrane 12 and the waterproof membrane 13.

[0025] Reference Figure 3 The inner surface of the board base 11 is fixedly connected with an anti-mold layer 15, which is a bamboo charcoal fiber woven layer. By setting the anti-mold layer 15, mold can be prevented from growing inside the flat board 1, thereby reducing the rotting of corrugated cardboard.

[0026] The working principle and usage process of this utility model are as follows: First, by setting a moisture-proof film 12 and a waterproof film 13, the waterproof and moisture-proof performance of the corrugated cardboard can be improved, preventing external moisture from entering the interior of the corrugated cardboard, thereby reducing the amount of moisture entering the interior of the corrugated cardboard. By setting a wear-resistant layer 14, the wear resistance of the surface of the corrugated cardboard can be improved, making the corrugated cardboard less prone to wear, thus protecting the moisture-proof film 12 and the waterproof film 13. By setting a moisture-proof rod 3 in the corrugated plate body 2, when the corrugated cardboard is used in a low-humidity environment, if moisture enters the interior of the corrugated cardboard, the moisture-proof rod will... The desiccant 31 inside the corrugated cardboard absorbs moisture that enters the cardboard, keeping the inside dry and preventing it from getting damp. This ensures the structure and lifespan of the cardboard. By setting the nano-silver ion antibacterial coating 4, when moisture enters the inside of the cardboard, the nano-silver ion antibacterial coating 4 can prevent bacteria from growing on the surface of the flat board 1 and the corrugated board 2, thus preventing mold growth and preventing the inside of the cardboard from rotting. By setting the anti-mold layer 15, mold can be prevented from growing inside the flat board 1, thereby reducing the chance of the cardboard rotting.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
