[0002] Corrugated paper is a board-shaped material made by gluing noodle paper and corrugated paper formed by corrugating rollers. It is generally divided into single corrugated board and double corrugated board. The corrugated board is made into corrugated boxes through die-cutting, creasing, nailing or gluing, which can protect the goods and facilitate storage and transportation.

[0013] Technical effects and advantages of the utility model:

[0014] 1. The water-absorbing sponge is arranged between two layers of non-water-absorbing graphene-based sponge layers, and the first layer of graphene-based sponge layer blocks external moisture to complete preliminary moisture-proofing, and two layers of graphene-based sponge layers are used to complete double-layer moisture-proofing, and the contact area between the graphene-based sponge layer and the sponge cloth is greatly reduced by separating the paper strips, and the contact area between the sponge cloth and the air is increased by setting the cavity, thereby improving the water absorption efficiency of the sponge cloth;

[0015] 2. By setting the separation strips, the cavity is formed, and when the corrugated cardboard is indented, the cavity setting can be used to increase the indentation effect, which is convenient for the subsequent bending of the cardboard into boxes.

[0016] 3. The corrugated cardboard structure is composed of a multi-layer structure, which can increase the overall strength of the cardboard. And through the setting of the graphene-based sponge layer and the sponge cloth layer, the elastic buffering force of the sponge itself can also prevent the items in the carton from directly colliding with the outside world during the transportation of the corrugated cardboard box, so as to protect the items inside the carton.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figure 1 - Figure 2The composite moisture-proof corrugated paperboard structure shown in the figure comprises two layers of outer layer paper 1, wherein the outer layer paper 1 is at the outermost side to contact the air outside, and is produced by kraft paper as raw material, which is a common existing technology and will not be described in detail here. One side of the outer layer paper 1 is fixedly provided with a corrugated core paper 3, and the corrugated core paper 3 is a common existing structure of the existing corrugated paper box, and will not be described in detail here. One side of the corrugated core paper 3 is fixedly connected to the corresponding graphene-based sponge layer 2, and one side of the other outer layer paper 1 is provided with a graphene-based sponge layer 2 and a sponge cloth layer 4 for moisture-proofing, wherein the graphene-based sponge layer 2 is composed of graphene material and sponge composite. The graphene sponge is composed of a plurality of graphene-based sponges, and has excellent adsorption performance and oleophilic and hydrophobic properties. Water droplets are spherical on the surface of the graphene sponge and will not penetrate the sponge. The water contact angle can reach more than 150°, while the oil contact angle is 0°. Therefore, the graphene-based sponge can absorb only oil but not water. The sponge cloth layer 4 is composed of different types of chemical fibers and has fluff on the surface. Most sponge cloths are specially treated and do not contain harmful substances such as fluorescent agents and bleaching agents. They have good water absorption. The graphene-based sponge layer 2 is provided with two layers, and both sides of the graphene-based sponge layer 2 are coated with a flame retardant coating, wherein the flame retardant coating is a flame retardant, which is a common existing technology and will not be described in detail here.

[0022] The sponge cloth layer 4 is located between the two graphene-based sponge layers 2, and a plurality of separation paper strips 5 are fixedly provided on both sides of the sponge cloth layer 4, and the plurality of separation paper strips 5 are arranged at equal distances;

[0023] One side of a plurality of separation paper strips 5 is fixedly connected to one side of a corresponding graphene-based sponge layer 2;

[0024] The graphene-based sponge layer 2 and the separation paper strip 5 are bonded together using a corrugated cardboard bonding machine, and then the separation paper strip 5 and the sponge cloth layer 4 are bonded together to complete the production of the cardboard. The corrugated cardboard bonding machine is an existing corrugated cardboard bonding technology, which will not be described in detail here.

[0025] A cavity 6 is formed between the two corresponding separation paper strips 5 and the graphene-based sponge layer 2 and the sponge cloth layer 4 .

[0026] The outer layer paper 1 corresponding to the corrugated core paper 3 corresponds to the inner wall of the carton when forming the carton, and the graphene-based sponge layer 2 and the sponge cloth layer 4 correspond to the outer layer of the carton, which is used to prevent moisture from the outside. The external humid air first contacts the outermost layer paper 1, and then contacts the first layer of graphene-based sponge layer 2, thereby intercepting most of the humid air. A small part of the humid air contacts the separation paper strip 5 through the first layer of graphene-based sponge layer 2 and enters the cavity 6, thereby making the humid air contact the sponge cloth layer 4 to thoroughly absorb the moisture in the humid air, and then the humid air is completely intercepted by the second layer of graphene-based sponge layer 2;

[0027] The surface of the separation paper strip 5 is coated with a waterproof layer to prevent humidity from affecting the hardness and quality of the separation paper strip 5 to the greatest extent, thereby increasing the service life of the separation paper strip 5.
