Technical Field

[0001] This utility model relates to the field of PVC exhibition board technology, specifically to a biodegradable PVC exhibition board. Background Technology

[0002] Biodegradable PVC display boards are made using photodegradable PVC composite films. This material retains the original properties of PVC, but through the addition of specific additives or the use of special manufacturing processes, it can gradually decompose in the natural environment, reducing pollution.

[0003] There are many existing technologies for PVC exhibition panels, such as:

[0004] Chinese Patent Application No. 202320863959.2 discloses a technology related to PVC board technology. To address the limitation that existing PVC boards, if a larger area of ​​PVC material is required for a specific task, necessitates custom-making a larger PVC board, which reduces work efficiency and extends working time, the invention addresses this limitation. The invention includes a first PVC board, with a second PVC board disposed on one side of the first PVC board. A gap groove is formed between the first and second PVC boards, and a flexible connecting post is disposed within the gap groove. One end of the flexible connecting post is bonded to the first PVC board, and the other end, away from the first PVC board, is bonded to the second PVC board. The invention also includes a mating connecting block disposed at one end of the first and second PVC boards.

[0005] However, existing biodegradable PVC exhibition boards are prone to damage or breakage during use due to the low strength and durability of biodegradable materials. This results in a short service life, requiring frequent replacements and consuming a lot of manpower and resources. Therefore, we propose a biodegradable PVC exhibition board. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Biodegradable PVC display boards are made using photodegradable PVC composite films. This material retains the original properties of PVC, but through the addition of specific additives or the use of special manufacturing processes, it can gradually decompose in the natural environment, reducing pollution.

[0024] Please see Figures 1-5 As shown, this embodiment provides a biodegradable PVC display board, including a PVC sheet 1. To prevent the PVC sheet 1 from deforming, the following is specifically described: biodegradable fiber boards 21 are symmetrically arranged at the top and bottom of the PVC sheet 1, with two biodegradable fiber boards 21 at the top and two at the bottom. A slot 213 is opened on the surface of the biodegradable fiber board 21 near the PVC sheet 1, and a through groove 212 is opened on the surface between two biodegradable fiber boards 21. A polylactic acid sheet 2 is slidably connected to the inner wall of the through groove 212. The polylactic acid sheet 2 is V-shaped and forms a triangular shape with the biodegradable fiber board 21. The polylactic acid sheet 2 and the through groove 212 are compatible. However, in the use of existing biodegradable PVC display boards, due to the low strength and durability of biodegradable materials, the display board is easily damaged or broken, resulting in a relatively short service life and requiring frequent replacement, which consumes a lot of manpower and resources.

[0025] The improvement in this embodiment is as follows:

[0026] In this PVC display panel, firstly, two biodegradable fiberboards 21 are set up to sandwich the polylactic acid sheet 2 in the middle. Then, the polylactic acid sheet 2 is attached to the inner wall of the biodegradable fiberboard 21. Next, the polylactic acid sheet 2 is fixed by multiple "V" shaped plates. When the V-shaped plates are placed between the two plates, they together form a triangular structure. This structure inherits the stability characteristics of a triangle, that is, it can maintain the stability of the shape under the action of external force, making the PVC sheet 1 more stable and less prone to deformation.

[0027] In this PVC display panel, a corn starch board 22 is set. The corn starch board 22 is a cushioning material made of organic raw materials. The corn starch board 22 has good impact energy absorption performance, which can absorb the impact energy received, reduce the damage to the internal board, and make the display panel more durable.

[0028] In order to prevent the biodegradable fiberboard 21 from moving, insert blocks 11 are fixedly connected to the top and bottom of the PVC sheet 1. The biodegradable fiberboard 21 has a slot 213 near the surface of the PVC sheet 1. The inner wall of the slot 213 is inserted into the outer surface of the insert block 11. First, the PVC sheet 1 is fixed to the insert block 11, and then the insert block 11 is fixed to the biodegradable fiberboard 21, so that the biodegradable fiberboard 21 does not move.

[0029] To reduce damage to the biodegradable fiberboard 21, a T-shaped groove 211 is provided on the outer surface of the biodegradable fiberboard 21, which is farther away from the PVC sheet 1. A T-shaped slider 221 is slidably connected to the inner wall of the T-shaped groove 211. A corn starch board 22 is fixedly connected to the outer surface of the T-shaped slider 221. First, the main component of the corn starch board 22 is corn starch, which is a cushioning material made from organic raw materials. Second, the corn starch board 22 has good impact energy absorption performance and can absorb the impact energy received, reducing mechanical damage to the product and thus reducing damage to the biodegradable fiberboard 21.

[0030] Secondly, to reduce damage to the board, ABS edge banding strips 32 are glued to the left and right sides of the PVC board 1, and a biodegradable transparent film 3 is glued to the outer surface of the corn starch board 22. The inner surface of the biodegradable transparent film 3 is glued to the outer surface of the ABS edge banding strips 32, and a biodegradable coating 31 is glued to the outer surface of the biodegradable transparent film 3. First, the biodegradable transparent film 3 waterproofs the board, and then the biodegradable coating 31 protects the biodegradable transparent film 3 and the board from stains and scratches, thereby reducing damage to the board.

[0031] Considering the possibility of water leakage at both ends of the board, polyurethane sealant 33 is bonded to the ends of the corn starch board 22, and PBAT waterproof board 34 is bonded to the outer surface of the polyurethane sealant 33. First, the polyurethane sealant 33 seals the PBAT waterproof board 34 at both ends of the board, thus preventing water leakage at both ends of the board.

[0032] In summary, the working principle of this solution is as follows:

[0033] The polylactic acid (PLA) board 2 is composed of multiple "V"-shaped plates. When the V-shaped plates are placed between two plates, they together form a triangular structure. This structure inherits the stability characteristics of a triangle, meaning it can maintain its shape under external force, making the biodegradable fiberboard 21 less prone to deformation. The non-deformable nature of the biodegradable fiberboard 21 also makes the PVC board 1 in the middle less prone to deformation. A cornstarch board 22 is added to the outside of the biodegradable fiberboard 21. Since the cornstarch board 22 is a cushioning material made from organic raw materials, it has good impact energy absorption performance, absorbing the impact energy and reducing damage to the internal boards, making the display board more durable. A biodegradable transparent film 3 waterproofs the board's perimeter. A biodegradable coating 31 protects the biodegradable transparent film 3 and the internal boards, preventing scratches. A polyurethane sealant 33 seals the PBAT waterproof board 34 at both ends of the board, preventing water from entering the interior of the display board from both ends, making the display board less prone to deformation and more durable.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
