[0002] A corrugated paperboard, also known as a corrugated board, is a multi-layer adhesive body, consisting of at least one layer of wavy core paper interlayer and one layer of paperboard. The application of corrugated paper is becoming more and more extensive, and in some fields, it begins to replace some other wood products and steel products. Traditional corrugated paper is basically composed of a layer of paper core and a paper panel, with insufficient strength, easy to deform and damage, and a short service life.

[0003] For example, for the high-strength composite corrugated paper with the application number 202122345554.3, the edge sealing structure of the corrugated paper in this application is relatively simple, and it is convenient and cost-saving to directly realize through the layer structure of the corrugated paper; by pasting moisture-proof paper on the surfaces of the first corrugated paperboard and the second corrugated paperboard, it is beneficial to avoid the buffer layer from failing due to moisture absorption, and through the setting of the upper waterproof protective film and the lower waterproof protective film, it is beneficial to protect the corrugated paper and improve its waterproof performance. However, the design structure of this corrugated paperboard is a diamond design, and the structural stability is poor.

[0004] Therefore, in view of this, in response to the existing structural deficiencies, research and improvement are carried out to propose a structurally reinforced composite corrugated paperboard. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] As Figure 1 - Figure 2 shown, a structurally reinforced composite corrugated cardboard includes a cardboard body 1. The cardboard body 1 includes an upper cardboard 2. A lower cardboard 3 is provided on the lower surface of the upper cardboard 2. A folding plate 4 is fixedly connected between the upper cardboard 2 and the lower cardboard 3. A cross plate 5 is fixedly connected at the position between the sharp corners of the folding plate 4. Honeycomb-shaped holes 6 are formed at the position between the concave corners of the folding plate 4, and the honeycomb-shaped holes 6 penetrate through the entire interior of the cardboard body 1. An upper trapezoidal hole 7 is formed above the cross plate 5, and the honeycomb-shaped holes 6 penetrate through the entire interior of the cardboard body 1. A lower trapezoidal hole 8 is formed below the cross plate 5, and the honeycomb-shaped holes 6 penetrate through the entire interior of the cardboard body 1.

[0021] By adopting the above technical solution, the folding plate 4 between the upper cardboard 2 and the lower cardboard 3 can form honeycomb-shaped holes 6. The honeycomb-shaped holes 6 can improve the strength and stability of the cardboard body 1 and play a role in structural reinforcement. At the same time, the transverse plate 5 forms an upper trapezoidal hole 7 and a lower trapezoidal hole 8 in the remaining space. The trapezoidal holes have good load-bearing capacity and can further improve the structural strength of the cardboard body 1.

[0022] As Figure 3 shown, an inner cardboard 9 is arranged inside the transverse plate 5, and the inner cardboard 9 is fixed in an adhesive form.

[0023] Furthermore, a number of filling holes 10 are formed inside the inner cardboard 9, and a flame retardant powder 11 is filled inside the filling holes 10.

[0024] Working principle: When using this structurally reinforced composite corrugated cardboard, first, the folding plate 4 between the upper cardboard 2 and the lower cardboard 3 can form honeycomb-shaped holes 6. The honeycomb-shaped holes 6 can improve the strength and stability of the cardboard body 1 and play a role in structural reinforcement. At the same time, the transverse plate 5 forms an upper trapezoidal hole 7 and a lower trapezoidal hole 8 in the remaining space. The trapezoidal holes have good load-bearing capacity and can further improve the structural strength of the cardboard body 1. The filling holes 10 inside the inner cardboard 9 can be filled with the flame retardant powder 11. After the cardboard body 1 filled with the flame retardant powder 11 burns, it can play a good flame retardant role. This is the working principle of this structurally reinforced composite corrugated cardboard.
