Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard technology, and more specifically, to high-density cardboard with surface anti-slip treatment. Background Technology

[0002] Corrugated cardboard, also known as corrugated paperboard, is made of at least one layer of corrugated paper and one layer of linerboard bonded together, and has good elasticity and extensibility. It is mainly used to manufacture cartons, carton fillings, and other packaging materials for fragile goods.

[0003] Currently available corrugated cardboard on the market typically has a smooth surface, making cartons made from it prone to slipping during transportation, which can damage the goods inside and result in poor performance. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model proposes a high-density cardboard with a surface anti-slip treatment. By setting an anti-slip layer, not only can the anti-slip performance of the cardboard be improved, but the anti-slip layer is also not easily damaged and has a longer service life.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] This utility model provides a high-density paperboard with a surface anti-slip treatment, including an anti-slip layer, an upper paper surface, a core paper layer, and a lower paper surface. The anti-slip layer is disposed above the upper paper surface, the core paper layer is disposed below the upper paper surface, and the lower paper surface is disposed below the core paper layer. The anti-slip layer includes a fiberglass mesh, a waterproof protective layer, an anti-slip coating, and anti-slip strips. The fiberglass mesh is bonded to the upper paper surface with an adhesive. The waterproof protective layer is disposed above the fiberglass mesh, and the anti-slip coating is disposed above the waterproof protective layer. Two or more anti-slip strips are evenly disposed on the anti-slip coating, and adjacent anti-slip strips are arranged in a staggered manner.

[0007] In a preferred embodiment of this invention, the core paper layer includes a rectangular support layer, support ribs, and spiral reinforcing strips. Two or more support ribs are evenly arranged in the rectangular support layer. Arc-shaped grooves are provided on both sides of the support ribs. A spiral reinforcing strip is provided between two adjacent support ribs, and the spiral reinforcing strip is fixedly connected to the inner wall of the arc-shaped groove.

[0008] In a preferred embodiment of this invention, the anti-slip strip has a wavy structure.

[0010] In a preferred embodiment of this invention, both the anti-slip strip and the raised edge are made of rubber material.

[0011] The beneficial effects of this utility model are as follows:

[0012] The high-density paperboard with surface anti-slip treatment proposed in this invention not only improves the anti-slip performance of the paperboard through the added anti-slip layer, but also makes the anti-slip layer less prone to damage and extends its service life. The cooperation between the supporting ribs and spiral reinforcing strips gives the core paper layer excellent compressive and bending resistance, and helps to improve the overall strength of the high-density paperboard.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] like Figure 1-4As shown, the embodiment provides a high-density paperboard with a surface anti-slip treatment, including an anti-slip layer 1, an upper paper surface 2, a core paper layer 3, and a lower paper surface 4. The anti-slip layer 1 is disposed above the upper paper surface 2, the core paper layer 3 is disposed below the upper paper surface 2, and the lower paper surface 4 is disposed below the core paper layer 3. The anti-slip layer 1 includes a fiberglass mesh 11, a waterproof protective layer 12, an anti-slip coating 13, and anti-slip strips 14. The fiberglass mesh 11 is bonded to the upper paper surface 2 with adhesive. The waterproof protective layer 12 is disposed above the fiberglass mesh 11, and the anti-slip coating 13 is disposed above the waterproof protective layer 12. Two or more anti-slip strips 14 are evenly disposed on the anti-slip coating 13, and adjacent anti-slip strips 14 are arranged in a staggered manner. In this embodiment, both the upper paper surface 2 and the lower paper surface 4 are bonded to the core paper layer 3 together with adhesive. The core paper layer 3 has advantages such as strong load-bearing capacity and ease of processing, and also plays a supporting role. The anti-slip layer 1 is bonded to the upper paper surface 2, preventing workers from slipping when handling high-density cardboard or placing it on the ground, thus facilitating its use. The fiberglass mesh 11, made of fiberglass material, has high mechanical properties and serves as the skeleton of the anti-slip layer 1, contributing to its overall strength. The waterproof protective layer 12 is an organic coating layer, preferably made of acrylic ester, which effectively prevents water from penetrating the cardboard, thereby improving its waterproof performance and extending its service life. The anti-slip coating 13 is preferably made of epoxy resin. The bottom end of the anti-slip strip 14 is embedded in the anti-slip coating 13, and the top surface of the anti-slip strip 14 is higher than the top surface of the anti-slip coating 13. Because the anti-slip strips 14 are arranged in a staggered pattern, there are localized uneven areas on the surface of the high-density cardboard, making it less slippery when workers handle the cardboard or place it on the ground.

[0021] Specifically, the core paper layer 3 includes a rectangular support layer 31, support ribs 32, and spiral reinforcing strips 34. Two or more support ribs 32 are evenly distributed within the rectangular support layer 31. Arc-shaped grooves 33 are provided on both sides of each support rib 32. A spiral reinforcing strip 34 is provided between adjacent support ribs 32, and the spiral reinforcing strip 34 is fixedly connected to the inner wall of the arc-shaped groove 33. In this embodiment, the upper paper surface 2 and the lower paper surface 4 are both bonded to the outer wall of the rectangular support layer 31 using adhesive. The support ribs 32 are arranged along the length of the rectangular support layer 31, and two or more support ribs 32 are arranged in parallel. The upper and lower end faces of the support ribs 32 are respectively attached to the upper and lower end faces of the inner side of the rectangular support layer 31, providing primary support to the rectangular support layer 31, thereby improving the compression resistance of the high-density paperboard. Simultaneously, the support ribs 32 also provide a certain degree of bending resistance to the high-density paperboard along its length. Spiral reinforcing strips 34 are also disposed inside the rectangular support layer 31. Two or more connection points are evenly distributed on the spiral reinforcing strips 34, and these connection points are fixed to the inner wall of the arc-shaped groove 33. This provides auxiliary support to the support ribs 32, preventing them from sliding laterally. This, in turn, provides the high-density paperboard with a certain degree of bending resistance along its width. Furthermore, the bending force applied to the spiral reinforcing strips 34 is evenly distributed and transferred to the support ribs 32. The support ribs 32 and the spiral reinforcing strips 34 work together to give the core paper layer 3 excellent compressive and bending resistance, and helps improve the overall strength of the high-density paperboard. In addition, high-density expanded foam is filled in the gaps between adjacent support ribs 32.

[0022] Specifically, the anti-slip strip 14 has a wavy structure. In this embodiment, the wavy surface of the anti-slip strip 14 is perpendicular to the top surface of the anti-slip coating 13.

[0023] Specifically, the top of the anti-slip strip 14 is provided with a raised edge 15, and the raised edge 15 is provided with serrations 16. In this embodiment, the raised edge 15 is integrally formed with the anti-slip strip 14, and the serrations 16 can increase the roughness at the edge of the raised edge 15, which helps to improve the anti-slip performance of the high-density cardboard.

[0024] Specifically, both the anti-slip strip 14 and the raised edge 15 are made of rubber. In this embodiment, the rubber material has advantages such as strong wear resistance and resistance to damage, which helps to improve the service life of the high-density paperboard.

[0025] This utility model has been described through preferred embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model.
