Abstract

The utility model belongs to the technical field of plywood, and discloses a waterproof plywood, which includes a multi-layer hot-pressed cortex, the outer surface of the cortex is covered with a PVC layer, and the PVC layer and the cortex are connected by an adhesive layer . The connection surface between the PVC layer and the cortex layer is a concave-convex surface. The inner layer of the PVC layer is set as a concave-convex surface and the board is more firmly bonded to prevent delamination. The utility model will now cover the PVC layer with the board skin layer of the prior art, which can effectively waterproof and moisture-proof, increase the service life, and also have high wear resistance, effectively solving the problems of poor waterproof effect and poor waterproof effect of the plywood in the prior art. Not durable technical issues.

Description

a waterproof plywood

technical field

The utility model belongs to the technical field of plywood and relates to a waterproof plywood.

Background technique

Plywood has the advantages of high structural strength and is widely used in furniture, construction and other industries.

The current production of plywood is to bond multiple layers of thin veneers with glue, then heat-press and dry, then cut and polish, and finally paint and shape. Although this kind of plywood has high structural strength, it is not waterproof. Once it is soaked in water or in a humid environment, moisture will enter the interior along the edge of the board and the gap, resulting in cracking and delamination of the board. And the paint layer of outer layer is not wear-resisting, scratches just can occur a little friction, long-time exposure to the sun also can cause paint to come off, and there is the technical problem that waterproof effect is poor, not durable in the plywood of prior art.

Contents of the invention

The purpose of the utility model is to solve the technical problems that the plywood of the prior art has poor waterproof effect and not durable, and provide a waterproof plywood with a simple structure to overcome the deficiencies of the prior art.

In order to achieve the above object, the utility model is achieved through the following technical solutions.

The utility model relates to a waterproof plywood, which comprises a multi-layer hot-pressed board skin layer, the main point of which is that the outside of the board skin layer is covered with a PVC layer, and the PVC layer and the board skin layer are connected by an adhesive layer.

As a further improvement, the connection surface between the PVC layer and the board skin layer is a concave-convex surface; the inner layer of the PVC layer is set as a concave-convex surface to bond more firmly with the board and prevent delamination.

As a further improvement, the thickness of the PVC layer is 1-1.5 mm; the thickness of the PVC layer is set between 1 and 1.5 mm, which will neither affect the strength of the board nor greatly increase the cost of the board.

The utility model will now cover the plywood layer of the prior art with a PVC layer, which can effectively waterproof and moisture-proof, increase the service life, and also have high wear resistance, effectively solving the problems of poor waterproof effect and poor waterproof effect of the plywood in the prior art. Not durable technical issues.

detailed description

With reference to the accompanying drawings, the utility model is a waterproof plywood, which includes a multi-layer hot-pressed cortex 2, the outer surface of the cortex 2 is covered with a PVC layer 1, and an adhesive layer 3 is passed between the PVC layer and the cortex. connect.

The connection surface between the PVC layer and the cortex layer is a concave-convex surface.

The thickness of the PVC layer is 1-1.5mm.

The 6 faces of the board cortex of the utility model are all covered with PVC layers, and the utility model can be made into a plate shape, or can be made into other forms according to the usage, for example: table legs, bed supports and the like.

The utility model will now cover the plywood layer of the prior art with a PVC layer, which can effectively waterproof and moisture-proof, increase the service life, and also have high wear resistance, effectively solving the problems of poor waterproof effect and poor waterproof effect of the plywood in the prior art. Not durable technical issues.
