METHOD FOR MANUFACTURING A LAMINATED WOOD MATERIAL Russian patent published in 2023 - IPC B27N3/00 B32B21/00 

FIELD: wood processing industry.

SUBSTANCE: wooden structures that can be used as prefabricated load-bearing elements in wooden housing construction for enclosing structures, carpentry and joinery products. Method for manufacturing a multilayer wood-based board material includes cutting a board or sheet wood-based material for making outer layers and connecting an inner layer from wood bark particles pressed together with them. For the manufacture of the inner layer, wood bark of one species or a mixture of wood species is used, before pressing the inner layer, the tree bark is dried and crushed to a size of 5-50 mm, the wood bark is pressed with simultaneous veneering on both sides with wood laminating, and at a process temperature of up to 140°C pressing is carried out with the addition of a binder.

EFFECT: strength characteristics of the structural material are increased, and the process of its manufacture is simplified.
