Abstract

The invention discloses worm-proof plywood and a preparation process thereof. The worm-proof plywood comprises eucalyptus veneers and worm-resistant modified glue used for bonding the eucalyptus veneers, wherein the eucalyptus veneers are glued in the direction where textures are perpendicular to one another. According to the worm-proof plywood, quaternary ammonium salt is added into the worm-resistant modified glue, and a grafting reaction is achieved between the quaternary ammonium salt and lignin, so that the worm-resistant modified glue can be more firmly combined with the eucalyptus veneers and the eucalyptus veneers cannot be easily peeled off; and meanwhile, the growth environment of worms and ants can be destroyed, the breeding of the worms and the ants, and the gnawing of the worms and the ants can be avoided.

Description

technical field [0001] The invention relates to the technical field of plywood, in particular to an insect-proof plywood and a preparation process thereof. Background technique [0002] Plywood is one of the commonly used materials for furniture and is a kind of wood-based panel. It is a three-layer or multi-layer plate-like material that is made of wood sections that are peeled into veneers or sliced ​​into veneers, and then glued with adhesives. Usually, odd-numbered layers of veneers are used, and the adjacent veneers Fiber directions are glued perpendicular to each other. [0003] Because the main material of plywood is wood, and wood is easily attacked by insects and ants during the use of time, causing the rot of plywood, which in turn leads to damage of furniture made of it and shortens its service life. Contents of the invention [0004] The object of the present invention is to provide a kind of anti-insect plywood and its preparation process for the deficiencie...
