Technical Field
[0001] The utility model relates to the technical field of white cardboard, in particular to a composite coated white cardboard. Background Art
[0002] Coated white cardboard is commonly used in the packaging industry. Coated whiteboard is a processed cardboard made by coating a white coating on the original cardboard and then finishing. It is mainly used for making packaging boxes after single-sided color printing. The performance characteristics of coated white cardboard: The coated surface of the coated white cardboard has a relatively high whiteness, good smoothness, ink absorbency and printing gloss. The cardboard itself also has good stiffness and folding resistance. Therefore, it can not only perform high-quality color offset printing and intaglio printing, but also meet the requirements of packaging. It is an excellent material for making medium and high-grade commodity packaging boxes.
[0003] At present, most coated white cardboards are multi-layer cardboard structures, generally divided into an outer layer, a filling layer and an inner layer, and are used for packaging by using this multi-layer cardboard structure.
[0004] However, the above-mentioned coated white cardboard has a simple structure and general overall cushioning performance, resulting in poor compressive resistance of the overall coated white cardboard. When an external force acts on the coated white cardboard, the coated white cardboard will be directly damaged. For this reason, we propose a composite coated white cardboard. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a composite coated white cardboard. By setting a buffer layer and using the cooperation of elastic columns and connecting strips, it is convenient to make the coated white cardboard have a good buffering effect by using the buffer layer. At the same time, the cooperation of the support sleeve, the support column and the support strip can further achieve buffering. Thus, after the external force is removed, the support body can also quickly make the elastic body and the buffer layer quickly return to their original states.
[0006] To achieve the above object, the utility model provides the following technical solution: A composite coated white cardboard, including a first waterproof layer, a filling layer is arranged on one side of the first waterproof layer, an inner layer is arranged on one side of the filling layer, a board core layer is arranged on one side of the inner layer, an antibacterial layer is arranged on one side of the board core layer, a second waterproof layer is arranged on one side of the antibacterial layer, a buffer layer is arranged between the inner layer and the board core layer, the buffer layer is composed of a plurality of buffer bodies, the buffer bodies buffer external forces, and the buffer bodies include:
[0007] An elastic body, which is fixedly arranged between the mutually close sides of the inner layer and the board core layer;
[0008] A support body, which is fixedly arranged inside the elastic body.
[0009] Preferably, the elastomer includes a plurality of elastic columns and a plurality of connecting bars for connecting the plurality of elastic columns, and the number of elastic columns and the number of connecting bars are both set to three, and the three elastic columns are arranged in a triangle.
[0010] Preferably, both the first waterproof layer and the second waterproof layer are formed by coating with a waterproof agent, and the antibacterial layer is made of a silver ion fiber material.
[0011] Preferably, the inner layer is made of bleached sulfate wood pulp or a mixture of partially bleached chemical straw pulp and white paper edge waste pulp, the board core layer is made of bamboo pulp fiber, and the filling layer is made of waste newspaper fiber.

[0013] Preferably, the buffer body is supported by rubber, and each buffer body is integrally formed, and the overall contour of the buffer body is triangular.
[0014] The technical effects and advantages of the present utility model:
[0015] By applying an external force to the coated white cardboard, the external force is transmitted to the buffer layer through transmission. At this time, the buffer body will buffer. Among them, the elastomer will deform rapidly to perform preliminary buffering. Subsequently, the further deformation of the elastomer will squeeze the support body, and the support body is used for secondary buffering. At the same time, the support body will also achieve a certain degree of support to prevent the buffer body from deforming excessively and resulting in inability to recover its original shape later. By utilizing the good deformation ability of the elastomer and the support body, the buffer layer has good buffering performance, so that the coated white cardboard has buffering ability to buffer the external force and prevent the coated white cardboard from being directly damaged due to the external force acting on it. And after the external force is removed, the support body can quickly drive the elastomer to recover together, so that the buffer layer can perform buffering again. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation manner
[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0021] The present invention provides a composite coated white cardboard as shown in Figures 1-3 which includes a first waterproof layer 1. A filling layer 2 is arranged on one side of the first waterproof layer 1. An inner layer 3 is arranged on one side of the filling layer 2. A board core layer 5 is arranged on one side of the inner layer 3. An antibacterial layer 6 is arranged on one side of the board core layer 5. A second waterproof layer 7 is arranged on one side of the antibacterial layer 6. A buffer layer 4 is arranged between the inner layer 3 and the board core layer 5. The buffer layer 4 is composed of a plurality of buffer bodies, and the buffer bodies buffer external forces. The buffer body includes: an elastomer 8, and the elastomer 8 is fixedly arranged between the mutually adjacent sides of the inner layer 3 and the board core layer 5; a support body 9, and the support body 9 is fixedly arranged inside the elastomer 8; when the coated white cardboard is in use, an external force acts on the coated white cardboard, and the external force is transmitted and acts on the buffer layer 4. At this time, the buffer body will buffer. Among them, the elastomer 8 will quickly deform to perform preliminary buffering. Subsequently, the further deformation of the elastomer 8 will squeeze the support body 9, and the support body 9 is used for secondary buffering. At the same time, the support body 9 will also provide a certain degree of support to prevent the buffer body from deforming excessively and resulting in inability to return to its original state later. By using the good deformation ability of the elastomer 8 and the support body 9, the buffer layer 4 has good buffering performance, so that the coated white cardboard has buffering ability to buffer external forces and prevent the coated white cardboard from being directly damaged by the external force acting on it. And after the external force is removed, the support body 9 can quickly drive the elastomer 8 to recover together, so that the buffer layer 4 can perform buffering again.
[0022] It should be further noted that the elastomer 8 includes a plurality of elastic columns 801 and a plurality of connecting bars 802 for connecting the plurality of elastic columns 801, and the number of elastic columns 801 and the number of connecting bars 802 are both set to three, and the three elastic columns 801 are arranged in a triangle; when an external force acts on the buffer layer 4, it will cause the plurality of elastic columns 801 and the plurality of connecting bars 802 to deform, and utilize the voids inside the elastomer 8, so as to facilitate the elastomer 8 to have sufficient deformation space, so that the elastomer 8 can perform good buffering. At the same time, the triangular arrangement of the elastic columns 801 and the connecting bars 802 makes the overall structure relatively stable. When the external force is removed, the elastomer 8 can quickly return to its original state.
[0023] It should be noted that the support body 9 includes a support sleeve 901 fixedly arranged inside the elastomer 8, three support bars 903 fixedly connected to the outer surface of the support sleeve 901, and a support column 902 fixedly connected to the inside of the support sleeve 901, and one end of each support bar 903 is fixedly connected to the outer surface of the corresponding elastic column 801; when the elastomer 8 deforms, it will squeeze the support sleeve 901, the support bars 903 and the support column 902, and the support sleeve 901, the support bars 903 and the support column 902 will deform, so as to perform buffering. The support column 902 can provide support, so that the support body 9 can support the elastomer 8 and prevent the buffer layer 4 from deforming excessively. Among them, the support bars 903 are used to connect the elastic columns 801 and the support sleeve 901, which can prevent the elastomer 8 from deforming excessively and also facilitate the elastomer 8 to quickly return to its original state after the external force is removed.
[0024] Furthermore, the buffer body is supported by rubber, and each buffer body is integrally formed, and the overall contour of the buffer body is triangular; the integrally formed buffer body can make the structures of the elastomer 8 and the support body 9 more stable, prevent the buffer body from being easily damaged or broken, and at the same time, the buffer body made of rubber can utilize the good buffering performance of rubber to perform buffering.
[0025] Furthermore, the first waterproof layer 1 and the second waterproof layer 7 are both formed by coating with a waterproof agent, and the antibacterial layer 6 is made of silver ion fiber material; the first waterproof layer 1 and the second waterproof layer 7 are both waterproof agents, and the waterproof agent is specifically a wax emulsion, which can make the whole coated white cardboard have good waterproof effect. The antibacterial layer 6 utilizes the good antibacterial performance of the silver ion fiber material, so that the coated white cardboard has good antibacterial performance.
[0026] Furthermore, the inner layer 3 is made of bleached sulfate wood pulp or a mixture of partially bleached chemical straw pulp and white paper edge waste pulp, the board core layer 5 is made of bamboo pulp fiber, and the filling layer 2 is made of waste newspaper fiber; the filling layer 2 made of waste newspaper can make the whole coated white cardboard relatively firm by using the filling layer 2, and at the same time, in cooperation with the inner layer 3 and the board core layer 5, the coated white cardboard with a multi-layer structure has good structural strength, so that the whole coated white cardboard can better withstand external forces.
