NOVELTY - Preparing a plywood comprises gluing three thin wood boards by using an adhesive, where adhesive comprises 20-30 pts. wt. modified resin, 3-5 pts. wt. modified graphene, 3-5 pts. wt. benzyl dimethylamine, 1-3 pts. wt. sulfated castor oil, 1-3 pts. wt. sodium dodecyl sulfate, 1-3 pts. wt. o-phenylphenol and 10-15 pts. wt. water. The adhesive is prepared by (i) mixing modified resin, sulfated castor oil, sodium dodecyl sulfate and water to obtain a mixture and (ii) ultrasonically processing the mixture and modified graphene, adding benzyl dimethylamine and stirring USE - The plywood is useful for Bakelite box (claimed). ADVANTAGE - The plywood: has excellent heat-resistant oxygen effect; ensure the normal use of Bakelite box; and enhance the fracture toughness of adhesive.
