Description

Technical Field

[0001] The utility model relates to the field of corrugated paperboards, in particular to a compression-resistant and flame-retardant corrugated paperboard. Background Art

[0002] Corrugated cardboard is a multi-layer adhesive body consisting of a wavy core paper interlayer and cardboard. It has high mechanical strength and good elasticity, and can withstand collisions during transportation. Therefore, it is widely used in making cartons and packaging materials for fragile goods. In addition, corrugated cardboard is also widely used in display racks, furniture, sports equipment manufacturing and other fields due to its unique structure and excellent compressive resistance. Corrugated cardboard can be classified according to the size of the grooves and the combination method. Its production focuses on environmental protection and cost savings.

[0003] Corrugated cardboard is a material widely used in carton making. Its main function is to provide effective protection for the items inside. However, in actual use, the corners of corrugated boxes are often most susceptible to external impacts. Such collisions often cause cardboard damage, thereby weakening its protective effect on the internal items. Therefore, improving the impact resistance of the corners of corrugated boxes is the key to improving its overall protection effect. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a compression-resistant and flame-retardant corrugated paperboard to solve the technical problem that the corners of the corrugated paperboard are most susceptible to external collisions, resulting in damage to the paperboard.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a compression-resistant flame-retardant corrugated paperboard, comprising a paperboard main body, a support mechanism is arranged on one side of the paperboard main body, the support mechanism comprises a reinforcing plate, a cavity is formed between the reinforcing plate and the paperboard main body, air ribs are arranged inside the cavity, and an easy-folding groove is arranged on the surface of the reinforcing plate.

[0006] By adopting the above technical solution, the air ribs are inflated by using an external inflation device, which brings significant beneficial effects. Through inflation, the air ribs provide effective support for the reinforcement plate and the paperboard body, which enhances the structural strength of the paperboard at the bend.

[0007] Furthermore, the easy-bending groove is used to provide a bending point for the reinforcement plate.

[0008] By adopting the above technical solution, the easy-folding groove provides a clear bending point for the reinforcement plate, making the folding of the corrugated cardboard more accurate and convenient, simplifying the folding process and improving production efficiency.

[0009] Furthermore, the cross section of the air rib is a rectangular structure.

[0010] By adopting the above technical solution, the rectangular air ribs provide a larger support area, which can effectively disperse the pressure, so that the reinforcement plate and the cardboard body can be more evenly supported when subjected to external force, which helps to improve the overall compression resistance of the cardboard.

[0011] Furthermore, the reinforcing plate is made of cardboard and is fixedly bonded to the cardboard body.

[0012] By adopting the above technical solution, firstly, since the reinforcement plate and the main body of the cardboard are made of the same material, namely cardboard, they can be better integrated, thereby enhancing the overall structural consistency.

[0013] Furthermore, the paperboard body includes a first core layer and a second core layer, and the surfaces of the first core layer and the second core layer are both provided with core surfaces.

[0014] By adopting the above technical solution, the double-core layer structure increases the thickness and layering of the cardboard, improves the compressive strength and load-bearing capacity of the cardboard, and makes it more able to withstand external pressure and impact.

[0015] Furthermore, a surface paper is arranged on the top of the first core layer, and a lining paper is arranged on the bottom of the second core layer.

[0016] By adopting the above technical solution, the surface paper as the outer layer of the paperboard is not only beautiful, but also can enhance the wear resistance and waterproofness of the paperboard and improve the resistance of the paperboard to the external environment.

[0017] Furthermore, a printing layer is arranged on the surface of the face paper, a coating layer is arranged on the surface of the printing layer, and a waterproof layer is arranged on the surface of the lining paper.

[0018] By adopting the above technical solution, the printing layer enables the paperboard to have better information transmission function, which is convenient for identification and tracking. At the same time, the coating layer enhances the wear resistance and waterproofness of the paperboard, protecting the printed content from fading or damage.

[0019] Furthermore, the surfaces of the coating layer and the face paper are coated with flame retardant.

[0020] By adopting the above technical solution, the coating of flame retardant significantly improves the fire resistance of cardboard, enabling it to slow down the burning speed when encountering a fire source, thus buying precious time for responding to the fire.

[0021] In summary, the utility model mainly has the following beneficial effects:

[0022] 1. The utility model uses a supporting mechanism and an external inflation device to inflate the air ribs, so that the air ribs can provide stable support for the reinforcement plate and the cardboard body. In this folding method, the special structural setting of the reinforcement plate and the air ribs significantly enhances the structural strength of the cardboard body at the bending part. This enhancement can not only effectively prevent the corners of the corrugated cardboard box from being bent and damaged during use, but also greatly improve the compression resistance and durability of the corrugated cardboard box, thereby better protecting the items inside. In this way, the overall quality of the corrugated cardboard box and the protection performance of the internal items are significantly improved;

[0023] 2. The utility model provides a cardboard main body, and the flame retardant can effectively improve the flame retardant performance of the cardboard. When the cardboard is exposed to a fire source, the flame retardant can significantly reduce the flammability of the cardboard, thereby reducing the possibility of fire. At the same time, the flame retardant can also form a protective barrier on the surface of the cardboard to slow down the spread of fire and buy more time for fire rescue, which protects personal and property safety to a certain extent.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0030] The following describes an embodiment of the utility model based on its overall structure.

[0031] Embodiment 1:

[0032] A compression-resistant flame-retardant corrugated paperboard, such as Figure 1-Figure 4 As shown, it includes a cardboard main body 1, and a support mechanism 2 is arranged on one side of the cardboard main body 1. The support mechanism 2 includes a reinforcing plate 201, and a cavity 202 is formed between the reinforcing plate 201 and the cardboard main body 1. An air rib 203 is arranged inside the cavity 202, and an easy-folding groove 204 is arranged on the surface of the reinforcing plate 201. The air rib 203 is inflated by an external inflation device, which brings significant beneficial effects. Through inflation, the air rib 203 provides effective support for the reinforcing plate 201 and the cardboard main body 1, which enhances the structural strength of the cardboard at the bending part. At the same time, the special structural setting of the reinforcing plate 201 and the air rib 203 can reduce the risk of bending and damage of corners during the folding process, thereby improving the compression durability of the corrugated box.

[0033] See also Figure 1 , Figure 2 , Figure 3 The easy-folding groove 204 is used to provide a bending point for the reinforcement plate 201. The easy-folding groove 204 provides a clear bending point for the reinforcement plate 201, making the folding of the corrugated cardboard more accurate and convenient, simplifying the folding process and improving production efficiency. At the same time, the easy-folding groove 204 can also ensure that the folded carton has a regular shape and a stable structure, further enhancing the compression resistance and durability of the carton. The clear bending point also reduces the errors that may occur during the folding process, thereby improving the overall quality and consistency of the product.

[0034] See also Figure 1 , Figure 2 , Figure 3 The cross section of the air rib 203 is a rectangular structure. The rectangular air rib 203 provides a larger support area and can effectively disperse the pressure, so that the reinforcing plate 201 and the paperboard body 1 can be supported more evenly when subjected to external force, which helps to improve the overall compression resistance of the paperboard. At the same time, the rectangular cross-section of the air rib 203 also increases the stability of the structure, preventing the paperboard from being deformed or damaged when impacted, and further protecting the carton and its internal items.

[0035] See also Figure 1 , Figure 2 , Figure 3 The reinforcing plate 201 is made of cardboard and is fixedly bonded to the cardboard main body 1. First, since the reinforcing plate 201 and the cardboard main body 1 are made of the same material, namely cardboard, they can be better integrated and the overall structural consistency is enhanced. At the same time, through fixed bonding, the reinforcing plate 201 and the cardboard main body 1 form a stable whole, which not only improves the strength and stability of the cardboard, but also effectively prevents separation or falling off during use.

[0036] Embodiment 2:

[0037] See also Figure 1, Figure 2 , Figure 4 The paperboard body 1 includes a first core layer 101 and a second core layer 102. The surfaces of the first core layer 101 and the second core layer 102 are both provided with core surfaces 103. The double core layer structure increases the thickness and layering of the paperboard, improves the compressive strength and load-bearing capacity of the paperboard, and makes it more able to withstand external pressure and impact. At the same time, the setting of the core surface 103 further enhances the bonding force between the core layers, making the paperboard more durable and not easy to delaminate or crack.

[0038] See also Figure 1 , Figure 2 , Figure 4 A face paper 104 is arranged on the top of the first core layer 101, and a lining paper 107 is arranged on the bottom of the second core layer 102. The face paper 104, as the outer layer of the paperboard, is not only beautiful, but also can enhance the wear resistance and waterproofness of the paperboard, and improve the resistance of the paperboard to the external environment. At the same time, the lining paper 107, as the inner layer of the paperboard, can provide additional protection to prevent internal objects from damaging the paperboard, and also enhance the overall structural stability of the paperboard.

[0039] See also Figure 1 , Figure 2 , Figure 4 The surface of the face paper 104 is provided with a printing layer 105, the surface of the printing layer 105 is provided with a coating layer 106, and the surface of the lining paper 107 is provided with a waterproof layer 108. The printing layer 105 enables the paperboard to have a better information transmission function, which is convenient for identification and tracking. At the same time, the coating layer 106 enhances the wear resistance and waterproofness of the paperboard, and protects the printed content from fading or being damaged. In addition, the waterproof layer 108 on the lining paper 107 further improves the moisture-proof performance of the paperboard, protects the internal items from moisture, and together improves the practicality and durability of the paperboard.

[0040] See also Figure 1 , Figure 2 , Figure 4 The surfaces of the coating layer 106 and the face paper 104 are coated with flame retardants. The coating of flame retardants significantly improves the fire resistance of the paperboard, so that it can slow down the burning speed when encountering a fire source, which wins precious time for dealing with the fire. At the same time, the flame retardant can also reduce the toxic smoke and heat generated when the paperboard burns, reducing the threat of fire to personal safety and pollution to the environment. It not only enhances the safety of the paperboard, but also makes it more suitable for occasions that require fire protection, thereby expanding the application range of the paperboard.

[0041] The implementation principle of the utility model is as follows: in the process of folding the corrugated cardboard into an outer corrugated cardboard box, first, the inside of the air rib 203 is inflated by using an external inflation device, and the air rib 203 is used to support the reinforcement plate 201 and the cardboard body 1. In this folding process, the structural form of the reinforcement plate 201 and the air rib 203 is conducive to improving the structural strength of the bending part of the cardboard body 1, avoiding the corner bending and damage of the corrugated cardboard box during use, thereby improving the compression resistance and durability of the corrugated cardboard box and improving the protection of the internal articles.

[0042] Parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art, and will not be described in detail here.
