FIELD: glues.
SUBSTANCE: present invention relates to an aqueous adhesive composition for lignocellulosic materials such as wood. The composition includes: component (i) in the form of one or more oxidized lignins, component (ii) in the form of one or more crosslinkers selected from crosslinkers based on β-hydroxyalkylamides and/or crosslinkers based on oxazolines, component (iii) in the form of one or more plasticizers selected from the group consisting of polyethylene glycols. The invention also relates to a method for producing a glued lignocellulosic product using the above aqueous adhesive composition and directly to the glued lignocellulosic product itself.
EFFECT: obtaining an inexpensive glue in production, in which corrosive and/or harmful materials are in reduced quantities or eliminated, having good adhesive properties, stable under various conditions, such as heat and humidity, providing excellent mechanical properties of lignocellulosic materials glued with it such as wood.
