Description

Flame-retardant plywood

Technical Field

The utility model relates to the technical field of plywood, in particular to flame-retardant plywood.

Background

Plywood is a three-layer or multi-layer plate material made up by using wood segments and making them be rotary-cut into single board or sliced into thin wood and using adhesive to make them be glued together, and usually using odd number of layers of single board and making the fibre directions of adjacent layers of single board be mutually perpendicular. The plywood is one of common furniture materials, is one of three large plates of an artificial plate, and can also be used as a material for airplanes, ships, trains, automobiles, buildings, packing boxes and the like. A group of veneers are typically assembled and glued perpendicular to each other in the direction of the adjacent layers of wood grain, and the skins and inner sheets are typically symmetrically disposed on either side of the center layer or core. The existing plywood has poor fireproof effect and cannot meet the market demand; on the other hand, the existing plywood has low strength, so that the service life of the plywood is short, and the plywood is easy to damage during transportation.
