The present application relates to the field of plywood preparation, and more particularly, it relates to a corrosion-resistant plywood and a preparation method thereof, comprising the following steps: S1: taking a plurality of veneers for drying, immersing the veneers in an anti-corrosion solution, The board and the anti-corrosion solution are subjected to vacuum immersion treatment, and taken out to obtain a pre-treated board; the anti-corrosion solution is composed of anti-corrosion agent, water-soluble phenolic resin, curing agent and water according to the mass ratio (0.4-0.6): (15-25): (1 ‑1.5): (95‑105); the preservative is any one of boric acid, borax, and disodium tetrahydrate octaborate; S2: drying the initially treated board prepared in step S1 to prepare a standby board; S3: apply adhesive on the spare plate prepared in step S2, and bond multiple spare plates to each other to obtain a composite plate; S4: hot-press and cut the composite plate prepared in step S3 to obtain a . The present application has the advantage of improving the corrosion resistance of plywood. |
