Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard technology, and in particular to a novel clean corrugated cardboard. Background Technology

[0002] Corrugated cardboard, also known as corrugated paperboard, is a multi-layered adhesive, mainly composed of at least one layer of corrugated core paper and one layer of paperboard bonded together. It has many advantages such as high mechanical strength, good elasticity, good extensibility, cushioning effect and low temperature influence. It is widely used in the packaging industry, including food packaging, electronic and electrical packaging, home building materials packaging and express packaging.

[0003] Currently, most corrugated cardboard has poor surface cleaning performance, making it difficult to remove stains once they adhere to it, affecting its appearance and usage scenarios. In addition, it lacks waterproof ability, easily becoming damp and softening when exposed to water, resulting in a significant decrease in structural strength and a shortened service life. To address these issues, we propose a new type of clean corrugated cardboard. Utility Model Content

[0004] The purpose of this invention is to provide a new type of clean corrugated cardboard to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A novel cleanable corrugated cardboard includes a first paper surface, the upper surface of which is provided with a cleaning coating, and multiple guide grooves formed on the upper surface of the first paper surface. A buffer layer is fixedly connected to the bottom surface of the first paper surface, a first reinforcing layer is fixedly connected to the bottom surface of the buffer layer, a corrugated core layer is fixedly connected to the bottom surface of the first reinforcing layer, a second reinforcing layer is fixedly connected to the bottom surface of the corrugated core layer, a sponge layer is fixedly connected to the bottom surface of the second reinforcing layer, and a second paper surface is fixedly connected to the bottom surface of the sponge layer.

[0007] In a further embodiment, the bottom surface of the second paper is provided with anti-slip texture, and the thickness of the cleaning coating is set to five micrometers to twenty micrometers.

[0008] In a further embodiment, the corrugated core layer has multiple reinforcing plates inside, and both the first and second reinforcing layers are made of woven glass fiber.

[0009] In a further embodiment, the upper surface of the corrugated core layer is provided with a first waterproof layer, and the bottom surface of the corrugated core layer is provided with a second waterproof layer.

[0010] In a further embodiment, the interior of the sponge layer is provided with activated carbon particles, and each of the flow channels is distributed in a vertical strip shape.

[0011] In a further embodiment, both the first waterproof layer and the second waterproof layer are polyethylene film layers.

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

[0013] This device utilizes a self-cleaning coating on its surface to decompose or remove surface stains through photocatalysis or physical wiping. A flow channel guides the liquid to flow quickly down the channel, preventing it from lingering on the cardboard surface. This, combined with the cleaning coating, enhances stain removal efficiency. The first and second waterproof layers on the upper and lower surfaces of the corrugated core effectively prevent moisture penetration, protecting the internal structure of the cardboard from dampness. The activated carbon particles within the sponge layer absorb moisture and odors from the air, providing a moisture-proof effect. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4In this utility model, a novel cleanable corrugated cardboard includes a first paper surface 1, a cleaning coating 2 on the upper surface of the first paper surface 1, multiple guide grooves 3 on the upper surface of the first paper surface 1, a buffer layer 4 fixedly connected to the bottom surface of the first paper surface 1, a first reinforcing layer 5 fixedly connected to the bottom surface of the buffer layer 4, a corrugated core layer 6 fixedly connected to the bottom surface of the first reinforcing layer 5, a second reinforcing layer 7 fixedly connected to the bottom surface of the corrugated core layer 6, a sponge layer 8 fixedly connected to the bottom surface of the second reinforcing layer 7, and a second paper surface 9 fixedly connected to the bottom surface of the sponge layer 8. The cleaning coating 2 is composed of nanomaterials such as nano-titanium dioxide and nano-silica, and has hydrophilic and photocatalytic properties. It can decompose organic stains on the surface under light conditions, and under the action of water droplets, the stains can slide off quickly with the water flow, thereby achieving a self-cleaning function. The buffer layer 4 has a honeycomb structure and is made of elastic materials, such as polyurethane foam, which can buffer the impact force on the corrugated cardboard from the outside.

[0023] The bottom surface of the second paper surface 9 is provided with anti-slip texture 10. The thickness of the cleaning coating 2 is set to five micrometers to twenty micrometers. The interior of the corrugated core layer 6 is provided with multiple reinforcing plates 13. The first reinforcing layer 5 and the second reinforcing layer 7 are both made of woven glass fiber, which can enhance the overall strength of the corrugated cardboard. The reinforcing plates 13 are made of rigid plastic, which can improve the compressive strength of the corrugated core layer 6. By setting anti-slip texture 10 on the bottom surface of the second paper surface 9, friction can be increased to prevent the cardboard from sliding and improve the safety of stacking and transportation.

[0024] The upper surface of the corrugated core layer 6 is provided with a first waterproof layer 11, and the bottom surface of the corrugated core layer 6 is provided with a second waterproof layer 12. The interior of the sponge layer 8 is provided with activated carbon particles. Each guide groove 3 is distributed in a vertical strip shape. The first waterproof layer 11 and the second waterproof layer 12 are both polyethylene film layers. By setting the first waterproof layer 11 and the second waterproof layer 12, sewage can be prevented from penetrating into the interior of the cardboard. By setting activated carbon particles in the sponge layer 8, some moisture and odors can be absorbed, extending the service life of the cardboard. By setting the sponge layer 8, internal impacts can be effectively absorbed, providing good protection for the internal items and reducing damage during transportation.

[0025] The working principle of this utility model is as follows:

[0026] When using this device, the surface cleaning coating 2 plays a self-cleaning role, decomposing or removing surface stains through photocatalysis or physical wiping. By setting the guide channel 3, liquid can be guided to flow down the channel quickly, avoiding stagnation on the cardboard surface. Together with the cleaning coating 2, it improves the stain removal efficiency. The buffer layer 4 can absorb external impact and reduce damage to the internal structure of the cardboard. The first reinforcing layer 5, the second reinforcing layer 7, and the reinforcing plate 13 can enhance the cardboard's resistance to compression and bending. The first waterproof layer 11 and the second waterproof layer 12 on the upper and lower surfaces of the corrugated core layer 6 can effectively block moisture penetration. The activated carbon particles in the sponge layer 8 can absorb moisture and odors in the air, playing a role in moisture prevention and air purification. The anti-slip texture 10 on the bottom surface of the second paper surface 9 increases the friction with the contact surface and prevents the cardboard from sliding during stacking or transportation.
