Technical Field

[0001] This utility model relates to the field of hollow board technology, specifically to high-strength moisture-proof hollow board. Background Technology

[0002] Hollow core board is a lightweight and environmentally friendly packaging material. Compared with cardboard boxes, hollow core board has obvious advantages, such as light weight, tensile strength, and good waterproof performance, which helps to protect the packaged products. Since the packaged products need to have strong load-bearing capacity, the strength of hollow core board needs to be increased. The existing solutions for increasing the strength of hollow core board are generally to increase the thickness and number of layers of the board. As a result, the packaging boxes are large in volume, occupy more storage space, and are not conducive to the transportation of goods. Based on this, a new technical solution is proposed to increase the strength of hollow core board. Utility Model Content

[0014] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] like Figure 1 , Figure 2As shown, the high-strength moisture-proof hollow board of this utility model includes a hollow board body 1, which is composed of an upper panel 2, a lower panel 3, and a three-dimensional support structure disposed between the two panels. The three-dimensional support structure includes multiple parallel support units 4, each support unit 4 having a hexagonal cross-section. The support units 4 form a hexagonal honeycomb structure, with a gap between adjacent support units 4. A reinforcing structure 6 is disposed within the gap. The reinforcing structure 6 is composed of two intersecting reinforcing ribs, with the upper and lower ends of the reinforcing ribs fixedly connected to the upper panel 2 and the lower panel 3, respectively. The combination of the hexagonal support units 4 and the reinforcing structure 6 improves the strength of the hollow board, which is beneficial for improving the strength of the manufactured packaging boxes.

[0016] like Figure 2 As shown, each support unit 4 has a hollow internal structure. The wall thickness of the support unit 4 increases gradually from its center to the edge, which improves the strength of the support unit 4. The hollow part of the support unit 4 is filled with a column made of polyurethane foam material. The polyurethane foam material layer 5 improves the shock absorption and cushioning effect of the support unit 4, which is beneficial to protecting the packaged products. Furthermore, anti-slip strips 7 are respectively provided on the upper panel 2 and the lower panel 3. The anti-slip strips 7 are integrally formed with the panels. Multiple anti-slip strips 7 are equally spaced on each panel. The distance between two adjacent anti-slip strips 7 is set to 1-10cm according to the area of ​​the hollow board body 1 to be produced. The height of each anti-slip strip 7 is no more than 3mm. The anti-slip strips 7 help to improve the anti-slip effect and also play a cushioning role.

[0017] like Figure 2 As shown, two "L"-shaped moisture-proof protective layers 8 are also provided. These moisture-proof protective layers 8 are waterproof composite films with a thickness of 0.3-1mm. In use, the side of the moisture-proof protective layer 8 facing the hollow board body 1 has a waterproof adhesive layer. One moisture-proof protective layer 8 is aligned with the front of the upper panel 2, and the moisture-proof protective layer 8 is slowly lowered, covering the anti-slip sheet inside as it falls. At this time, the side of the "L"-shaped structure is the downward bending part located on the side of the supporting structure. After the moisture-proof protective layer 8 is adhered, it covers the upper end and one side of the upper panel 2. The other moisture-proof protective layer 8 is then pressed... Apply the two moisture-proof protective layers 8 to the lower panel 3 and the other side in the opposite direction. At this time, the two moisture-proof protective layers 8 cover and seal the top, bottom, left and right sides of the hollow board body 1, providing good waterproof and moisture-proof effect for the hollow board body 1. Finally, apply the sealing layer 9 to the two uncovered sides of the hollow board body 1, further improving the moisture-proof effect of the hollow board body 1. Moreover, after the hollow board body 1 is cut, it can be resealed at both ends with the sealing layer 9. When a specially made hollow board is required, multiple hollow board bodies 1 with the same structure can be stacked to make double or multiple thick hollow boards, which improves the application range.

[0018] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
