Description

Technical Field

[0001] The utility model relates to the technical field of honeycomb paperboards, in particular to an environmentally friendly honeycomb paperboard. Background Art

[0002] Honeycomb paperboard is made according to the principle of natural honeycomb structure. It is a new type of environmentally friendly and energy-saving material with a sandwich structure, which is made by connecting corrugated paper into countless hollow three-dimensional regular hexagons by gluing to form an integral load-bearing member - the paper core, and gluing surface paper on both sides.

[0003] There are many existing technologies for honeycomb paperboard, such as:

[0004] Chinese patent announcement number CN212171493U discloses an environmentally friendly honeycomb paperboard, which includes a paperboard reinforced resin outer frame arranged between a paperboard inner sealing plate and a paperboard outer sealing plate, wherein the paperboard reinforced resin outer frame is respectively adhered to the edges of the outer surfaces of the opposite sides of the paperboard inner sealing plate and the paperboard outer sealing plate, and a paperboard reinforced resin horizontal strip and a paperboard reinforced resin vertical strip are arranged between the paperboard inner sealing plate and the paperboard outer sealing plate, and the paperboard reinforced resin horizontal strip, the paperboard reinforced resin vertical strip, and the paperboard reinforced resin outer frame are integrally formed.

[0005] The existing honeycomb paperboard has limited strength, and its strength will be greatly reduced after being stained with water. Even if the wet paperboard is dried again, it cannot be used anymore, resulting in a waste of materials. In addition, the honeycomb paperboard is not aesthetically pleasing when used as a support for exhibits. For example, the environmentally friendly honeycomb paperboard proposed in the above patent only adds a resin frame to the surface of the paperboard, which still cannot solve the problem of being unable to be used anymore after being stained with water.

[0006] In view of this, we propose an environmentally friendly honeycomb paperboard to improve the shortcomings of the existing technology. Utility Model Content

[0019] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example

[0021] See also Figure 1-Figure 2 As shown, this embodiment provides an environmentally friendly honeycomb paperboard, including a paper core 10, with facial paper 20 provided on the top and bottom of the paper core 10, the paper core 10 is used to support the facial paper 20 and provide a buffer for the facial paper 20 when the facial paper 20 is impacted, the facial paper 20 is used to protect the paper core 10, the side wall of the paper core 10 is provided with a side panel 30, the side panel 30 is used to increase the overall aesthetics of the honeycomb paperboard, and the outer surface of the paper core 10 is coated with an adhesive layer, and the adhesive layer is used to prevent water from entering the inside of the paper core 10.

[0022] Working principle: When the environmentally friendly honeycomb paperboard provided by the utility model is used, the paper core 10 is used to support the facial paper 20, and provide a buffer for the facial paper 20 when the facial paper 20 is impacted. The facial paper 20 is used to protect the paper core 10, and the side panels 30 are used to increase the overall aesthetics of the honeycomb paperboard. The adhesive layer coated on the surface of the paper core 10 is used to prevent water from entering the inside of the paper core 10.

[0023] In order to prevent water from entering the paper core 10, the facial tissue 20 includes several layers of paper, and temporary glue is coated between each layer of paper; the material of the adhesive layer is water-based glue; the temporary glue is sticky enough to fix paper or other materials on the surface, but will not leave residue or damage the raw materials when removed. It is usually used in occasions such as stickers, notes, posters, etc. that need to be replaced frequently. When the paper on the surface of the facial tissue 20 is damaged, just tear off the paper and replace it with new paper.

[0024] Considering the need to enhance the strength of the paper core 10, the material of the paper core 10 is long fiber pulp; long fiber pulp usually comes from softwood species, such as pine, fir, etc. These pulps have longer fiber lengths, and the paper core 10 made of these pulps has better strength and durability.

[0025] In order to further protect the paper core 10, a water-absorbing layer is provided between the surface of the paper core 10 and the adhesive layer; the water-absorbing layer is water-absorbing cotton filled on the surface of the paper core 10, and the water-absorbing cotton is provided with water-soluble pigments, which will change color when exposed to water. In addition, the side panel 30 is made of transparent material and has patterns on it. Whether water has entered the paper core 10 can be judged based on whether the water-absorbing cotton changes color. If the water-absorbing cotton is found to change color, it only needs to be replaced with a new one.

[0026] The environmentally friendly honeycomb paperboard provided in the utility model is used to support the facial paper 20 through the paper core 10, and provide cushioning for the facial paper 20 when the facial paper 20 is impacted. Specifically, the paper core 10 is composed of a series of intersecting paperboard honeycombs to form a honeycomb-like structure, which makes the paper core 10 light, high-strength and good cushioning performance; the facial paper 20 is used to protect the paper core 10. Specifically, the viscosity of the temporary glue is enough to fix the paper or other materials on the surface, but it will not leave residues or damage the raw materials when it is removed. It is usually used in occasions such as stickers, notes, posters, etc. that need to be replaced frequently. When the paper on the surface of the facial paper 20 is damaged, just replace it. The paper is torn off and replaced with new paper; the side panels 30 are used to increase the overall aesthetics of the honeycomb paperboard. Specifically, the side panels 30 are made of transparent material and are provided with patterns; the adhesive layer coated on the surface of the paper core 10 is used to prevent water from entering the inside of the paper core 10, and the paper core 10 is further protected by a water-absorbing layer arranged between the surface of the paper core 10 and the adhesive layer. Specifically, the water-absorbing layer is water-absorbing cotton filled on the surface of the paper core 10. The water-absorbing cotton is provided with water-soluble pigments, which will change color when exposed to water. Whether water has entered the paper core 10 can be judged based on whether the water-absorbing cotton changes color. If the water-absorbing cotton is found to change color, it is only necessary to replace it with a new one.
