Abstract

The invention discloses a preparation method of plywood for a bakelite box. The plywood is prepared by gluing three veneers with an adhesive, and the adhesive comprises the following raw materials in parts by weight: 20-30 parts of modified resin, 3-5 parts of modified graphene, 3-5 parts of benzyl dimethylamine, 1-3 parts of sulfated castor oil, 1-3 parts of sodium dodecyl sulfate, 1-3 parts of o-phenylphenol and 10-15 parts of water; a molecular chain of the modified resin contains a large number of phenothiazine structures, and a six-membered ring is sandwiched between two benzene rings, so that lone pair electrons of sulfur atoms are delocalized on three rings, nitrogen-hydrogen bonds of phenothiazine are easy to break, the sulfur atoms in molecules can be oxidized to form sulfoxide and sulfone compounds, and the adhesive has a very good thermal oxidation resistance effect; and adhesive failure of the plywood does not occur in the use process of the plywood, normal use of the bakelite box is guaranteed, a molecular side chain of the modified resin contains a polyimide molecular chain, and the polyimide molecular chain is matched with the modified graphene, so that the fracture toughness of the adhesive can be enhanced, and the adhesive effect of the adhesive is better.

Description

technical field [0001] The invention relates to the technical field of preparation of bakelite boxes, in particular to a method for preparing plywood for bakelite boxes. Background technique [0002] Plywood is a three-layer or multi-layer board-like material that is made of wood sections that are peeled into veneers or sliced ​​into thin wood, and then glued with adhesives. Usually, odd-numbered veneers are used, and adjacent layers of veneers are used. The fiber direction of the plywood is glued vertically to each other. Plywood is one of the commonly used materials for furniture. The boards are arranged symmetrically on both sides of the center layer or the board core, and the slabs made of glued veneers criss-crossed according to the direction of wood grain are pressed under heating or non-heating conditions, and the number of layers is generally odd , a few also have even numbers, the difference in physical and mechanical properties in the vertical and horizontal direc...
