The invention discloses an environment-friendly flame-retardant and corrosion-resistant plywood and a preparation method thereof, comprising the following steps: (1) veneer pretreatment; (2) irradiation treatment; (3) vacuum heating impregnation; (4) secondary drying; (5) gluing; (6) hot pressing; (7) edge trimming and sanding; namely, the environment-friendly flame-retardant and corrosion-resistant plywood is obtained. The adhesive used in the environmentally friendly flame-retardant and corrosion-resistant plywood provided by the invention is environmentally friendly and non-toxic, has high bonding performance, flame retardant performance and anti-corrosion performance, and can improve the mechanical properties of wood. Since no formaldehyde is added, it will not It has formaldehyde emission, and the chitosan and cellulose nanocrystals added at the same time belong to green environmental protection materials, which are environmentally friendly, low in production cost and good in economic benefits. |
