Description

Technical Field

[0001] The utility model relates to the technical field of plywood, in particular to an acid-resistant, alkali-resistant and corrosion-resistant plywood. Background Art

[0002] Plywood is a three-layer or multi-layer plate material made by peeling wood segments into veneers or planing wood blocks into veneers, and then gluing them with adhesive. It is usually made of an odd number of veneers, and the fibers of adjacent veneers are glued perpendicular to each other. After searching, the Chinese patent publication number CN214188734U discloses a plywood, which includes a surface board, a back board, and a core board placed between the surface board and the back board. The surface board and the back board are located on both sides of the core board and connected to the core board. A surface layer is arranged on the side of the surface board away from the core board, and the surface layer is arranged as a bamboo mat. The surface board, the core board, the back board, and the surface layer are all provided with adhesive layers between the layers. This application has the effect of energy saving and environmental protection.

[0003] Although the above technical solution can ensure the long service life of the plywood and ensure the good energy-saving and environmental protection effect of the plywood, the T-blocks and T-slots are arranged on both sides of the core board during use. Only the core boards of two adjacent plywood boards are connected, and other layers cannot be connected, which is prone to cracking. Although the contact area of ​​the adhesive can be increased, thereby improving the stability of the overall structure, the connection method is single and cannot effectively improve the connection effect between the boards.

[0009] Preferably, the annular ring and the connecting column are integrally formed with the adhesive layer, which facilitates the forming of the annular ring and the connecting column of the limiting column.

[0010] Preferably, the protective layer includes a corrosion-resistant layer bonded to the outer surface of the outer layer board, the outer surface of the corrosion-resistant layer is bonded with a flame-retardant layer, and the outer surface of the flame-retardant layer is bonded with a wear-resistant layer, which can increase the corrosion resistance, flame retardancy and wear resistance of the plywood.

[0011] Preferably, the corrosion-resistant layer is made of epoxy resin and has good chemical stability, thereby achieving acid-resistant, alkali-resistant and corrosion-resistant properties.

[0025] like Figures 3 to 6 As shown, a limiting connection mechanism is provided between the base plate 11 and the outer plate 13, and the limiting connection mechanism includes a limiting column 151. A plurality of limiting holes 152 matching the limiting columns 151 are sequentially provided on the sides of the base plate 11 and the outer plate 13 that are close to each other. The limiting columns 151 and the limiting holes 152 are interference fit.

A plurality of slots 155 are provided in an annular array on the outer surface of the limiting column 151, and a connecting column 156 fixedly connected to two annular rings 154 is embedded inside the slot 155. The annular ring 154 and the connecting column 156 are integrally formed with the adhesive layer 12. When the plywood body 1 is produced, firstly, corresponding limiting holes 152 are opened on the outer surfaces of the base plate 11 and the outer layer plate 13, and then adhesive is applied to the outer surfaces of the base plate 11 and the outer layer plate 13 and the limiting holes 152, and then the limiting column 151 is inserted into the limiting hole 152 on the base plate 11, and then the two outer layer plates 13 are clamped on both sides of the base plate 11 through the limiting column 151, and the adhesive is formed between the base plate 11 and the outer layer plate 13.

In addition, the T-shaped connecting plates 21 and the T-shaped slots 22 are formed on the entire plywood body 1 rather than on a single layer, which can increase the overall strength of the two plywood boards when connected, making it less likely for the plywood boards to crack at the connection, thereby improving practicality. This solves the problem that the T-shaped blocks and T-shaped slots of the existing plywood boards are both arranged on both sides of the core board, and the two adjacent plywood boards are only connected to each other, while the other layers cannot be connected and are prone to cracking.
