Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard technology, specifically to an antistatic and flame-retardant corrugated cardboard. Background Technology

[0002] Corrugated paper, also known as corrugated cardboard, is made by bonding at least one layer of corrugated paper and one layer of linerboard. It has good elasticity and extensibility. It is mainly used to manufacture cartons, carton fillings, and other packaging materials for fragile goods. It is made by pulping straw pulp and waste paper to create a base paper similar to cardboard, which is then mechanically rolled into a corrugated shape. Finally, it is bonded to linerboard using adhesives such as sodium silicate. Packaging cartons made from corrugated paper are convenient for product transportation and storage.

[0003] In the existing technology, corrugated cardboard is generally made of face paper, core paper and liner paper bonded together. When packaging boxes made of corrugated cardboard are used to transport heavy goods, hand holes are opened on the side of the box. However, due to the insufficient strength and toughness of corrugated cardboard, the hand holes are easily torn due to the heavy force during handling. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an antistatic and flame-retardant corrugated cardboard. Through the triangular structure design between multiple sets of support strips, the first and second support layers are supported, which can increase the compressive strength of the cardboard body. At the same time, the elastic support blocks are squeezed, causing them to deform and compress the internal elastic balls, which has a certain buffering effect and improves the tear resistance and deformation resistance of the corrugated cardboard.

[0005] This utility model provides the following technical solution: an antistatic and flame-retardant corrugated cardboard, comprising: a cardboard body, the cardboard body being composed of a first connecting layer, a reinforcing layer, and a second connecting layer, the reinforcing layer being located at the bottom of the first connecting layer, and the second connecting layer being fixedly connected to the bottom of the reinforcing layer;

[0006] The reinforcing layer is used to increase the overall strength of the cardboard body. The reinforcing layer consists of a first support layer, multiple sets of support strips, a second support layer, and multiple sets of elastic support blocks. The first support layer is located between the first connecting layer and the second connecting layer. The multiple sets of support strips are all fixedly connected to the bottom of the first support layer. The second support layer is fixedly connected to the bottom of the multiple sets of support strips. The multiple sets of elastic support blocks are all located inside the multiple sets of support strips.

[0007] As a preferred embodiment of this utility model, the first support layer is fixedly connected to the first connecting layer, and the second support layer is fixedly connected to the second connecting layer.

[0008] As a preferred embodiment of this utility model, the multiple sets of support bars are designed in a triangular structure, and the multiple sets of support bars form a receiving groove.

[0009] As a preferred embodiment of this utility model, the elastic support block is located inside the receiving groove, and the interior of the elastic support block has a hollow structure design, with multiple sets of elastic balls fixedly connected inside the elastic support block.

[0010] As a preferred embodiment of this utility model, a first connecting groove is provided at one end of the first support layer near the multiple sets of support bars, and the interior of the first connecting groove is filled with flame-retardant particles.

[0011] As a preferred embodiment of this utility model, a second connecting groove is provided at one end of the second support layer near the multiple sets of support bars, and conductive fibers are embedded inside the second connecting groove.

[0012] As a preferred embodiment of this utility model, multiple sets of connecting strips are fixedly connected inside both the first connecting layer and the second connecting layer, and the multiple sets of connecting strips are fixedly connected to each other to form a triangular structure design.

[0013] The beneficial effects of this utility model are:

[0014] 1. In this utility model, the design of the reinforcing layer and the triangular structure design between multiple sets of support strips support the first support layer and the second support layer, thereby increasing the compressive strength of the cardboard body. When the support strips are under pressure, they compress the elastic support block, causing the elastic support block to deform and compress the internal elastic ball, which plays a certain buffering role, improving the tear resistance and deformation ability of the corrugated cardboard, thereby increasing the service life of the corrugated cardboard.

[0015] 2. In this utility model, the multiple sets of connecting strips inside the first connecting layer and the second connecting layer can increase the tensile strength of the first connecting layer and the second connecting layer, preventing the cardboard body from tearing and affecting its use.

Detailed Implementation

[0021] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Example:

[0023] like Figures 1 to 4 As shown, an antistatic and flame-retardant corrugated cardboard includes: a cardboard body 1, which is composed of a first connecting layer 2, a reinforcing layer 3, and a second connecting layer 4. The reinforcing layer 3 is located at the bottom of the first connecting layer 2, and the second connecting layer 4 is fixedly connected to the bottom of the reinforcing layer 3.

[0024] The reinforcing layer 3 is used to increase the overall strength of the cardboard body 1. The reinforcing layer 3 consists of a first support layer 5, multiple sets of support strips 6, a second support layer 7, and multiple sets of elastic support blocks 8. The first support layer 5 is located between the first connecting layer 2 and the second connecting layer 4. The multiple sets of support strips 6 are all fixedly connected to the bottom of the first support layer 5. The second support layer 7 is fixedly connected to the bottom of the multiple sets of support strips 6. The multiple sets of elastic support blocks 8 are all located inside the multiple sets of support strips 6.

[0025] In this embodiment, the first support layer 5 is fixedly connected to the first connecting layer 2, and the second support layer 7 is fixedly connected to the second connecting layer 4. The multiple sets of support bars 6 are designed in a triangular structure, and the multiple sets of support bars 6 form a receiving groove 9. When the cardboard body 1 is in use, the first support layer 5 and the second support layer 7 are supported by the triangular structure between the multiple sets of support bars 6, so as to increase the compressive strength of the cardboard body 1.

[0026] In this embodiment, the elastic support block 8 is located inside the receiving groove 9. The interior of the elastic support block 8 has a hollow structure design. Multiple sets of elastic balls 10 are fixedly connected inside the elastic support block 8. When the support bar 6 is subjected to pressure, it squeezes the elastic support block 8, causing the elastic support block 8 to deform and squeeze the elastic balls 10 inside, which plays a certain buffering role, improves the tear resistance and deformation ability of the corrugated cardboard, and thus improves the service life of the corrugated cardboard.

[0027] In this embodiment, the first support layer 5 has a first connecting groove 11 at one end near the multiple sets of support strips 6. The first connecting groove 11 is filled with flame-retardant particles 12. When the cardboard body 1 is used, the flame-retardant particles 12 can increase the flame-retardant effect of the cardboard body 1. The second support layer 7 has a second connecting groove 13 at one end near the multiple sets of support strips 6. The second connecting groove 13 is embedded with conductive fibers 14. The conductive fibers 14 can increase the anti-static effect of the cardboard body 1 and effectively prevent static electricity accumulation and discharge.

[0028] In this embodiment, multiple sets of connecting strips 15 are fixedly connected inside the first connecting layer 2 and the second connecting layer 4. The multiple sets of connecting strips 15 are fixedly connected to each other to form a triangular structure design. When the cardboard body 1 is in use, the multiple sets of connecting strips 15 inside the first connecting layer 2 and the second connecting layer 4 can increase the tensile strength of the first connecting layer 2 and the second connecting layer 4, preventing the cardboard body 1 from tearing and affecting its use.

[0029] Implementation plan: When the cardboard body 1 is in use, the triangular structure design between multiple sets of support strips 6 supports the first support layer 5 and the second support layer 7, thereby increasing the compressive strength of the cardboard body 1. When the support strips 6 are under pressure, they compress the elastic support block 8, causing the elastic support block 8 to deform and compress the internal elastic ball 10, which has a certain buffering effect, improving the tear resistance and deformation ability of the corrugated cardboard, thereby increasing the service life of the corrugated cardboard. When the cardboard body 1 is in use, the multiple sets of connecting strips 15 inside the first connecting layer 2 and the second connecting layer 4 increase the tensile strength of the first connecting layer 2 and the second connecting layer 4, preventing the cardboard body 1 from tearing.
