[0004] Based on the above patent, the design is reasonable, the structure is simple and stable, and the practicability is strong; it not only has the properties of being waterproof, moisture-proof and corrosion-resistant, but also has high overall strength, and is suitable for popularization and use. However, when the plywood is in use, the colloid on the board may fall off due to moisture erosion after long-term use, and the board may crack, so that the inside will be corroded by moisture and cause damage. In actual use, the plywood may be damaged by friction, wear and external forces, requiring maintenance and replacement, which reduces the practicability and service life of the plywood. Therefore, the present application proposes a corrosion-resistant and wear-resistant plywood. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a corrosion-resistant and wear-resistant plywood, which adjusts the humidity change between the boards through a water-absorbing plate, improves the durability of the boards through a wear-resistant layer and a wear-resistant film, protects the plywood through PVC edge sealing, improves the use effect of the plywood, and achieves the effect of increasing the service life.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A corrosion-resistant and wear-resistant plywood comprises a first base plate and a second base plate. The first base plate is fixedly connected with protrusions on both sides of the bottom end. The second base plate is provided with a slot in the middle of both ends. The inner walls of the slots on both sides are clamped on the outer walls of the protrusions on both sides.

[0008] Furthermore, a water absorbing plate is fixedly connected to the top of the second base plate, the top outer wall of the water absorbing plate is arranged on the bottom outer wall of the first base plate, and the material of the water absorbing plate is set to be a wood fiberboard.

[0009] Furthermore, outer walls of the first substrate and the second substrate at opposite ends are fixedly connected with wear-resistant layers, the material of the wear-resistant layers is set to polyurethane, and ends of the wear-resistant layers on both sides away from the first substrate and the second substrate are fixedly connected with wear-resistant films.

[0010] Furthermore, the outer walls of the first substrate and the second substrate are fixedly connected with PVC edge bands.

[0011] The utility model has the following beneficial effects:

[0012] In the utility model, the first substrate and the second substrate are fixed together by the convex block being clamped in the clamping groove, and they can still be fixed together even if the colloid falls off. The water absorption plate helps to adjust the humidity between the first substrate and the second substrate to prevent expansion or contraction caused by humidity changes, thereby improving the stability of the overall plywood. The wear-resistant layer and the wear-resistant film protect the surfaces of the first substrate and the second substrate from wear and scratch, thereby improving the durability of the board and helping to improve the appearance quality and waterproof and moisture-proof capabilities of the plywood. At the same time, the edges of the first substrate and the second substrate are sealed by the PVC edge banding tape to effectively prevent moisture from penetrating into the interior of the board. The PVC material has certain impact resistance and wear resistance, which helps to protect the edges of the plywood from external impact and wear, thereby achieving the effect of increasing the service life of the plywood.

[0018] 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.

[0019] Reference Figure 1-3 The utility model provides an embodiment: a corrosion-resistant and wear-resistant plywood, including a first substrate 1 and a second substrate 2, wherein the left and right sides of the bottom end of the first substrate 1 are fixedly connected with protrusions 4, and the middle parts of the left and right ends of the second substrate 2 are provided with card grooves 5, and the inner walls of the card grooves 5 on both sides are clamped on the outer walls of the protrusions 4 on both sides.

[0020] Furthermore, by moving the first substrate 1 to drive the protrusion 4 to slide in the slot 5 of the second substrate 2, the first substrate 1 and the second substrate 2 are fixedly installed according to the mortise and tenon structure, thereby preventing the colloid from falling off and the plates from separating.

[0021] A water-absorbing plate 3 is fixedly connected to the top of the second substrate 2, and the top outer wall of the water-absorbing plate 3 is arranged on the bottom outer wall of the first substrate 1. The material of the water-absorbing plate 3 is set to be a wood fiberboard, and the outer walls of the opposite ends of the first substrate 1 and the second substrate 2 are fixedly connected to a wear-resistant layer 6, and the material of the wear-resistant layer 6 is set to be polyurethane, and the ends of the wear-resistant layers 6 on both sides away from the first substrate 1 and the second substrate 2 are fixedly connected to wear-resistant films 7, and the outer walls around the first substrate 1 and the second substrate 2 are fixedly connected to PVC edge banding tapes 8.

[0022] Furthermore, the moisture absorbing plate 3 helps to adjust the humidity between the first substrate 1 and the second substrate 2, and prevents expansion or contraction caused by humidity changes, thereby improving the stability of the overall plywood. The wear-resistant layer 6 and the wear-resistant film 7 protect the surfaces of the first substrate 1 and the second substrate 2 from wear and scratches, thereby improving the durability of the board and helping to improve the appearance quality and waterproof and moisture-proof capabilities of the plywood. At the same time, the edges of the first substrate 1 and the second substrate 2 are sealed by the PVC edge banding tape 8, effectively preventing moisture from penetrating into the interior of the board. The PVC material has certain impact resistance and wear resistance, which helps to protect the edges of the plywood from external impact and wear.

[0023] Working principle: First, the first substrate 1 and the second substrate 2 are fixed together by clamping the protrusion 4 in the clamping groove 5. Even if the colloid falls off, they can still be fixed together. The water-absorbing plate 3 helps to adjust the humidity between the first substrate 1 and the second substrate 2 to prevent expansion or contraction caused by humidity changes, thereby improving the stability of the overall plywood. The wear-resistant layer 6 and the wear-resistant film 7 protect the surfaces of the first substrate 1 and the second substrate 2 from wear and scratches, improve the durability of the board, and help to improve the appearance quality and waterproof and moisture-proof capabilities of the plywood. At the same time, the PVC edge banding tape 8 seals the edges of the first substrate 1 and the second substrate 2 to effectively prevent moisture from penetrating into the interior of the board. The PVC material has certain impact resistance and wear resistance, which helps to protect the edges of the plywood from external impact and wear, thereby increasing the service life of the plywood.
