Description

Technical Field

[0001] The utility model relates to a fireproof and high temperature resistant plywood, belonging to the technical field of stationery production. Background Art

[0002] Plywood is a three-layer or multi-layer plate-like material made by peeling wood segments into veneers or planing wood blocks into thin wood, and then gluing them together with adhesive. Usually, an odd number of veneers are used, and the fibers of adjacent veneers are glued perpendicular to each other. There are many types of plywood, and high-temperature resistant and fire-resistant plywood is an important component among them. However, the overall strength of existing high-temperature resistant plywood is low, and it is easy to deform under high temperature environment. After the glue layer and the board are connected by pressing, it is still easy to fall off as a whole under high temperature. After the flame-retardant glue layer falls off, the board is very easy to break under high temperature environment, thereby causing the collapse of buildings, homes, etc., causing safety hazards. In addition, the edges around the board are easily worn, and gaps will be generated when the boards are spliced ​​together, affecting the connection effect between the boards. Utility Model Content
