FIELD: chemistry.
SUBSTANCE: invention relates to the production of wood-chip composite materials, namely a binder for the production of chipboards, plywood, wood fibre boards, and the like materials. The adhesive composition comprises carbamide-formaldehyde resin, a hardener, and a modifying additive, which is a polyacrylamide solution containing a crosslinking component.
EFFECT: production of an adhesive composition that provides increased strength of wood materials, the production of non-toxic wood materials with a lower cost.
