METHOD OF GLUING WOOD MATERIALS Russian patent published in 2012 - IPC C09J5/00 C09J161/24 

FIELD: chemistry.

SUBSTANCE: synthetic glue is applied onto an acid hardener-containing surfaces to be glued. The surfaces are joined and the glued components are placed between poles of a permanent electromagnet such that magnetic field lines are directed perpendicular to the glue joint with field intensity of (3-24)×10⁴ A/m. Hardening of the glue takes place in the magnetic field, where the acid hardener used is maleic acid.

EFFECT: use of the combined effect of magnetic field and maleic acid as a hardener for gluing wood materials improves strength characteristics of glue joints.
