Description

Technical Field

[0001] This application relates to the field of corrugated cardboard technology, specifically to a type of corrugated cardboard resistant to ultraviolet aging. Background Technology

[0002] Corrugated cardboard is a multi-layered adhesive with high mechanical strength, capable of withstanding collisions and drops during handling. The corrugations of the cardboard resemble interconnected arches, arranged side by side and supporting each other to form a triangular structure, which has good mechanical strength. It can also withstand a certain amount of pressure on a flat surface and is elastic, providing good cushioning. It can be made into pads or containers of various shapes and sizes as needed, and is simpler and faster than plastic cushioning materials.

[0003] According to a corrugated cardboard disclosed in Chinese Patent Publication No. CN214606415U, it includes a base layer, a non-woven waterproof layer on the upper side of the base layer, a corrugated first corrugated paper on the upper side of the non-woven waterproof layer, a first cushioning layer, a first mesh fiber layer, and a first face paper layer on the upper side of the first corrugated paper, a second corrugated paper on the upper side of the first face paper, a second cushioning layer, a second mesh fiber layer, and a second face paper layer on the upper side of the second corrugated paper, a corrugated third corrugated paper on the upper side of the third corrugated paper, a cardboard layer on the upper side of the third corrugated paper, and a wear-resistant layer on the upper side of the cardboard layer. The crests and troughs of the third corrugated paper are staggered from those of the second and first corrugated papers, which not only increases the strength of the corrugated cardboard but also increases its compressive strength, helping to maintain the integrity of the goods during transportation.

[0004] However, this patent still has some shortcomings in actual use. Corrugated cardboard needs to be in contact with the external environment for a long time during use, and its weather resistance is the key to ensuring the stable use of the cardboard for a long time. However, this patent lacks the ability to resist UV aging when exposed to ultraviolet light for a long time, resulting in a short service life in outdoor use. In this regard, this application improves the ability to resist UV aging while ensuring low cost, and provides a UV-resistant corrugated cardboard to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a UV-resistant corrugated cardboard that can improve the UV resistance of corrugated cardboard without significantly increasing actual costs. This solves the problem that existing corrugated cardboard is prone to accelerated aging due to prolonged exposure to UV light when used outdoors for extended periods.

[0006] To achieve the above objectives, this application provides the following technical solution: an anti-ultraviolet aging corrugated cardboard, comprising a reinforced corrugated cardboard body, wherein a protective component for protection is installed on the outer side of the reinforced corrugated cardboard body, and a protective component for enhanced protection is installed on the outer side of the protective component;

[0007] The protective assembly includes two adhesive layers bonded to the top and bottom of the reinforced corrugated cardboard body, a surface layer bonded to the top of the top adhesive layer, a bottom layer bonded to the bottom of the bottom adhesive layer, and two UV-resistant layers bonded to the outside of the surface layer and the outside of the bottom layer, respectively.

[0008] By adopting the above technical solutions, the ability of corrugated cardboard to resist ultraviolet aging can be improved without significantly increasing the actual cost.

[0009] Furthermore, the protective component includes an abrasion-resistant layer adhered to the bottom of the bottom UV-resistant layer and a waterproof layer coated on the bottom of the abrasion-resistant layer.

[0010] By adopting the above technical solution, the outer surface can achieve a wear-resistant and waterproof effect.

[0011] Furthermore, the reinforced corrugated cardboard body, adhesive layer, surface layer, bottom layer, UV-resistant layer, and abrasion-resistant layer are combined to form the corrugated cardboard body.

[0012] By adopting the above technical solution, packaging work becomes easier.

[0013] Furthermore, the waterproof layer is coated on the outside of the corrugated cardboard body and encloses the corrugated cardboard body inside.

[0014] By adopting the above technical solution, the waterproof layer can effectively waterproof the outside of the corrugated paper body.

[0015] Furthermore, the waterproof layer is chlorinated polyethylene, and the wear-resistant layer is an elastic polyurethane wear-resistant coating.

[0016] By adopting the above technical solution, the elastic polyurethane wear-resistant coating has good wear resistance and ductility, thereby increasing the maximum wear resistance of the corrugated cardboard surface.

[0017] Furthermore, the reinforced corrugated cardboard body includes at least three corrugated cardboards, which are stacked together, with the opposite sides of two adjacent corrugated cardboards fixed to each other, and the corrugations of two adjacent corrugated cardboards are staggered.

[0018] By adopting the above technical solutions, the reinforced corrugated cardboard body can have extremely strong compressive strength and load-bearing capacity, enabling it to be used stably as a base cardboard.

[0019] Furthermore, the adhesive layer is an environmentally friendly water-based adhesive layer, and the surface layer is a high-density white cardboard layer.

[0020] By adopting the above technical solution, an effective bonding effect can be achieved. The surface of the high-density white cardboard is smooth and flat, and it can be used as the inner side of the packaging.

[0021] Furthermore, the bottom layer is a flame-retardant cardboard layer, and the UV-resistant layer is a UV absorber coating layer.

[0022] By adopting the above technical solution, the bottom layer can effectively protect the outer side of the reinforced corrugated cardboard body and effectively block and absorb external ultraviolet rays.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] This UV-resistant corrugated cardboard, through the combined use of protective components, abrasion-resistant layers, and waterproof layers on the outer side of the reinforced corrugated cardboard body, enhances the UV-resistant properties of the corrugated cardboard without significantly increasing actual costs. This allows the corrugated cardboard to be used stably outdoors for an extended period, giving the entire cardboard excellent UV protection performance and effectively improving its weather resistance to meet the needs of outdoor protection and transportation, thereby significantly enhancing the practicality of the corrugated cardboard.

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0031] Please see Figures 1 to 4 This application provides a technical solution: an anti-ultraviolet aging corrugated cardboard, comprising a reinforced corrugated cardboard body 1, a protective component 200 for protection installed on the outside of the reinforced corrugated cardboard body 1, and a protective component for enhanced protection installed on the outside of the protective component 200; through the combined use of the protective component 200, the abrasion-resistant layer 3, and the waterproof layer 4 on the outside of the reinforced corrugated cardboard body 1, the anti-ultraviolet aging ability of the corrugated cardboard can be improved without significantly increasing the actual cost, thereby enabling the corrugated cardboard to be used stably outdoors for a longer period of time, giving the entire cardboard excellent UV protection performance, effectively improving its weather resistance to meet the needs of outdoor protection and transportation, and thus effectively improving the practicality of the corrugated cardboard.

[0032] In this embodiment, the protective component 200 is a structure used to provide weather protection for the outer side of the reinforced corrugated cardboard body 1.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, the protective component 200 includes two adhesive layers 201 bonded to the top and bottom of the reinforced corrugated cardboard body 1, a surface layer 202 bonded to the top of the top adhesive layer 201, a bottom layer 203 bonded to the bottom of the bottom adhesive layer 201, and two UV-resistant layers 204 bonded to the outside of the surface layer 202 and the outside of the bottom layer 203, respectively.

[0034] It should be noted that the reinforced corrugated cardboard body 1 includes at least three corrugated cardboards, which are stacked and arranged in a stacked manner. The opposite sides of two adjacent corrugated cardboards are fixed to each other, and the corrugations of two adjacent corrugated cardboards are staggered. This gives the reinforced corrugated cardboard body 1 extremely strong compressive strength and load-bearing capacity, enabling it to be used stably as a base cardboard.

[0035] In addition, the adhesive layer 201 is an environmentally friendly water-based adhesive layer, which can effectively bond the surface layer 202 and the bottom layer 203 to stably cover both sides of the reinforced corrugated cardboard body 1. The environmentally friendly water-based adhesive is an adhesive that uses water as a dispersion medium and has the advantages of being environmentally friendly, non-toxic, non-polluting, non-flammable, and safe to use, so that the fixed cardboard can meet the needs of product packaging.

[0036] Meanwhile, the surface layer 202 is a high-density white cardboard layer. High-density white cardboard is a sturdy, thick, and smooth paper that is commonly used for printing and packaging. This paper is made entirely from bleached chemical pulp and is fully sized, giving it high stiffness and strength. Its smooth and flat surface makes it suitable for use as the inner side of packaging.

[0037] In addition, the bottom layer 203 is a flame-retardant paperboard layer, which can effectively protect the outside of the reinforced corrugated cardboard body 1. Flame-retardant paper is a general term for a type of paper with non-combustible or difficult-to-burn properties. It has high strength and appearance properties and excellent flame-retardant properties. Flame-retardant paper is usually divided into two categories. One category refers to paper made from asbestos fibers that does not undergo any changes in fire. The other category refers to paper in which flame-retardant chemicals are added to the pulp or plant fibers are treated with flame retardants to obtain flame-retardant properties.

[0038] It should also be noted that the UV-resistant layer 204 is a UV absorber coating layer. UV absorbers are light stabilizers that can absorb the ultraviolet rays in sunlight and fluorescent light sources without changing themselves. In conjunction with the surface layer 202 and the bottom layer 203, they can effectively block and absorb external ultraviolet rays, thereby providing effective protection for the reinforced corrugated cardboard body 1.

[0039] In this embodiment, the protective component is a structure used to reinforce and protect the outer side of the overall cardboard.

[0040] like Figure 1 and Figure 4 As shown, the protective component includes an abrasion-resistant layer 3 bonded to the bottom of the bottom UV-resistant layer 204 and a waterproof layer 4 coated to the bottom of the abrasion-resistant layer 3.

[0041] It should be noted that the reinforced corrugated cardboard body 1, adhesive layer 201, surface layer 202, bottom layer 203, UV-resistant layer 204, and wear-resistant layer 3 are combined to form the corrugated cardboard body. The waterproof layer 4 is coated on the outside of the corrugated cardboard body and encloses the corrugated cardboard body inside. The waterproof layer 4 is chlorinated polyethylene, which enables the waterproof layer 4 to provide a comprehensive and effective waterproof effect on the outside of the corrugated cardboard body. Chlorinated polyethylene is a commonly used waterproof coating material with good waterproof performance, aging resistance, and chemical corrosion resistance. The waterproof layer 4 can also be other waterproof coatings with the same effect.

[0042] In addition, the wear-resistant layer 3 is an elastic polyurethane wear-resistant coating. The elastic polyurethane wear-resistant coating has good wear resistance and ductility, which can increase the surface wear resistance of the corrugated cardboard to a maximum extent, so that it can play a wear-resistant protection role for a long time.

[0043] It should also be noted that after the corrugated cardboard body is folded into a box, the wear-resistant layer 3 is located on the outside, while the surface layer 202 is located on the inside. This allows the wear-resistant layer 3 to come into contact with the outside ground or objects, thus providing protection. The surface layer 202 is used for placing the packaged items inside.

[0044] The working principle of the above embodiments is as follows:

[0045] During use, the waterproof layer 4 effectively blocks external water, preventing it from easily eroding the interior. The wear-resistant layer 3 provides the outer side of the cardboard with good wear resistance, meeting the needs of long-term use and packaging transportation. The UV-resistant layer 204 effectively blocks and absorbs external ultraviolet rays, preventing them from penetrating and affecting the reinforced corrugated cardboard body 1. Thus, the overall cardboard structure based on the reinforced corrugated cardboard body 1 can well meet the needs of outdoor packaging box transportation.

[0046] Compared with existing technologies, this UV-resistant corrugated cardboard, through the combined use of the protective component 200, the abrasion-resistant layer 3, and the waterproof layer 4 on the outer side of the reinforced corrugated cardboard body 1, can improve the UV resistance of the corrugated cardboard without significantly increasing the actual cost. This allows the corrugated cardboard to be used stably outdoors for a longer period of time, giving the entire cardboard excellent UV protection performance and effectively improving its weather resistance to meet the needs of outdoor protection and transportation. This effectively improves the practicality of the corrugated cardboard and solves the problem that existing corrugated cardboard is prone to accelerated aging due to prolonged exposure to ultraviolet light when used outdoors for a long time.
