Description

Technical Field

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

[0002] Corrugated cardboard is a multi-layer adhesive body, which consists of at least one layer of corrugated core paper and one layer of cardboard. It has high mechanical strength and can withstand collisions and falls during transportation. The actual performance of corrugated boxes depends on three factors: the characteristics of the core paper and cardboard and the structure of the box itself.

[0003] At present, double corrugated paper core boards are more or less provided with elastic materials, which are used to improve the overall rebound effect after impact and prevent the paper core from being folded and damaged. However, when the impacting object is a sharp object, the elastic material provided in the paperboard cannot protect it. If the sharp object destroys the elastic material structure, the corrugated paperboard will directly lose its rebound effect and will also have penetrating wounds. So far, the existing corrugated paperboard cannot effectively resist the impact or scratch of sharp objects.

[0004] Therefore, it is very necessary to invent a novel high-elastic double-corrugated paper core corrugated paperboard. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a novel high-elastic double-corrugated paper core corrugated paperboard, comprising an outer corrugated paperboard layer, an elastic armor layer and an inner corrugated paperboard layer, the inner sides of the outer corrugated paperboard layer and the inner corrugated paperboard layer are compounded with the elastic armor layer, and the outer corrugated paperboard layer and the inner corrugated paperboard layer have the same structure;

[0006] The elastic armor layer includes a high-elastic armor net, an elastic leveling layer A and an elastic leveling layer B. The elastic leveling layer A and the elastic leveling layer B have the same structure. A high-elastic armor net is compositely arranged between the elastic leveling layer A and the elastic leveling layer B. The elastic leveling layer A and the elastic leveling layer B are compositely connected with the outer corrugated cardboard layer and the inner corrugated cardboard layer respectively.

[0007] Preferably, the outer corrugated paperboard layer and the inner corrugated paperboard layer include a corrugated paper core, a core face paper and a core bottom paper, the corrugated paper core is compounded between the core face paper and the core bottom paper, and the core bottom paper is compounded and bonded to the elastic armor layer.

[0008] Preferably, the elastic leveling layer A and the elastic leveling layer B are rubber layers made of high-elastic waterproof rubber, and the elastic leveling layer A and the elastic leveling layer B are provided with recessed areas that fit with the high-elastic armor mesh.

[0009] Preferably, the high-elastic armor mesh is compositely arranged in the recessed areas of the A elastic leveling layer and the B elastic leveling layer, and the high-elastic armor mesh is a mesh body woven from a plurality of spiral metal bodies.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The elastic armor layer of the utility model is a reinforcing core of the corrugated cardboard. The high-elastic armor net arranged in the elastic armor layer has extremely strong elasticity through a spiral structure, and the rebound effect is more excellent. Moreover, because it is made of metal material, it can effectively block the penetration of external sharp objects, effectively protect the subsequent layer structure, and avoid penetration wounds on the entire cardboard. In addition, the high-elastic armor net can also reduce the depth of the concave deformation caused by subsequent impacts. BRIEF DESCRIPTION OF THE DRAWINGS

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

[0020] The utility model provides a novel high-elastic double-corrugated paper core corrugated paperboard, comprising an outer corrugated paperboard layer 1, an elastic armor layer 2 and an inner corrugated paperboard layer 3, wherein the inner sides of the outer corrugated paperboard layer 1 and the inner corrugated paperboard layer 3 are composited with the elastic armor layer 2, the outer corrugated paperboard layer 1 and the inner corrugated paperboard layer 3 have the same structure, and the elastic armor layer 2 is a reinforced core structure of the corrugated paperboard.

[0021] The elastic armor layer 2 includes a high-elastic armor net 21, an A elastic leveling layer 22 and a B elastic leveling layer 23. The A elastic leveling layer 22 and the B elastic leveling layer 23 have the same structure. The high-elastic armor net 21 is compositely arranged between the A elastic leveling layer 22 and the B elastic leveling layer 23. The A elastic leveling layer 22 and the B elastic leveling layer 23 are compositely connected with the outer corrugated cardboard layer 1 and the inner corrugated cardboard layer 3 respectively. The arrangement of the A elastic leveling layer 22 and the B elastic leveling layer 23 can reduce the subsequent composite difficulty. Embodiment 1:

[0022] Specifically, the outer corrugated paperboard layer 1 and the inner corrugated paperboard layer 3 include a corrugated paper core 11, a core face paper 12 and a core bottom paper 13, the corrugated paper core 11 is compounded between the core face paper 12 and the core bottom paper 13, the core bottom paper 13 is compounded and bonded with the elastic armor layer 2, and the corrugated paper core 11 is formed by stacking one or more layers of corrugated paperboard.

[0023] Specifically, the elastic leveling layer A 22 and the elastic leveling layer B 23 are rubber layers made of high-elasticity waterproof rubber. The elastic leveling layer A 22 and the elastic leveling layer B 23 are provided with recessed areas that fit with the high-elastic armor mesh 21. The elastic leveling layer A 22 and the elastic leveling layer B 23 have extremely high elasticity and waterproofness. When hit by a blunt object, the elastic leveling layer A 22 and the elastic leveling layer B 23 rebound, thereby reducing the depth and size of subsequent recessed deformation.

[0024] Specifically, the high-elastic armor mesh 21 is compositely arranged in the recessed area of ​​the A elastic leveling layer 22 and the B elastic leveling layer 23. The high-elastic armor mesh 21 is a mesh body woven from multiple spiral metal bodies.

[0025] When a blunt object hits the corrugated cardboard, the outer corrugated cardboard layer 1 of the corrugated cardboard is dented, and the impact force is transmitted to the elastic armor layer 2 through the outer corrugated cardboard layer 1. The high-elastic armor mesh 21 of the elastic armor layer 2 blocks the impact force, and the outer A elastic leveling layer 22 and B elastic leveling layer 23 are used to buffer the impact force and subsequently help the outer corrugated cardboard layer 1 structure to rebound. In addition, when a sharp object hits the outer corrugated cardboard layer 1 of the corrugated cardboard, the sharp object will directly penetrate the outer corrugated cardboard layer 1, and the A elastic leveling layer 22 or B elastic leveling layer 23 of the elastic armor layer 2 will preferentially apply resistance to it. If the A elastic leveling layer 22 or B elastic leveling layer 23 is penetrated later, the high-elastic armor mesh 21 will forcibly block the sharp object from penetrating deeper, effectively reducing the degree of damage to a minimum.

[0026] 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.
