Anti-corrosion and pressure-resistant composite board for educational toys

The invention provides an anti-corrosion and pressure-resistant composite board for educational toys, and belongs to the technical field of composite materials. The anti-corrosion and pressure-resistant composite board comprises a thin film layer on the surface, a polymer base material layer and a pressing wood layer, wherein the polymer base material layer is prepared from components in parts byweight as follows: 60-75 parts of modified polyester and 5-15 parts of a toughening agent; modified polyester is prepared from reaction raw materials including a cross-linking agent, a modifying agent, terephthalic acid and ethanediol by copolymerization; the pressing wood layer is prepared by following steps: after being crushed, sawdust leftover materials are uniformly stirred with aluminum powder, magnesium powder, copper powder, iron powder and nickel powder, and a mixture is pressed; the composite board is coated with an anti-corrosion agent and a flame retardant. The composite board is of a multilayer structure
