Problems solved by technology

[0002] Due to the humid and hot environment of the bathroom cabinets, the cabinets are easily deformed and mildewed, which shortens the service life of bathroom furniture
In the existing technology, the acrylic veneer is applied on both sides of the bathroom cabinet, and then the acrylic edge is formed, and the wooden board is covered with plastic, so as to achieve the purpose of waterproof and anticorrosion, but the disadvantage of this is The investment in equipment is high, and the cost of raw materials is also high; there is also a painting operation on the outer surface of the bathroom cabinet board. The disadvantage of this is that the stability of the process is poor, and the cost is also high
[0003] In addition, in the bathroom, due to temperature changes, the bathroom cabinet board is prone to local stress changes, resulting in local delamination and peeling of the bathroom cabinet board. For example, the waterproof layer on the surface of the wooden cabinet board falls off, which not only causes The water-absorbing mildew, and the peeling off of the surface waterproof layer seriously affects the appearance of the bathroom cabinet

Abstract

The invention belongs to the technical field of bathroom furniture, in particular to a weather-resistant multi-layer bathroom cabinet board and a preparation method thereof. The bathroom cabinet boardcomprises a core layer and fiber cloth layers arranged on two sides of the core layer; waterproof rubber layers are further arranged on the outer layers of the fiber cloth layers; the core layer is formed by mixing and pressing wood flakes with a first adhesive; each of the waterproof rubber layers comprises rubber particles, a second adhesive and polypropylene short fiber; according to the invention, through the arrangement of the fiber cloth layers and the waterproof rubber layers on the two sides of the core layer formed by pressing the wood flakes and the first adhesive, and through the excellent waterproof performance of the waterproof rubber layers formed by pressing the rubber particles, the problem of mildew and rot caused by bacteria and microorganisms breeding in the bathroom cabinet plate due to water absorption in a dark and humid environment for a long time is avoided; at the same time, the waterproof rubber layers have certain water-repellent capacity, so that the warpage deformation of the bathroom cabinet plate due to water absorption is avoided, the weather resistance of the bathroom cabinet board is greatly improved, and the service life of the bathroom cabinet board is prolonged.
