Abstract RU 2645674 C2

FIELD: chemistry.

SUBSTANCE: present invention relates to a wood glue material composition, a wood adhesive composition and a process of its production, as well as to the lignocellulosic array. Adhesive composition comprises a first component formed from at least one isocyanate and at least one polyester, and a second component containing at least one amino resin. Said polyester comprises at least one ethylene oxide moiety and at least one hydroxyl group. Amino resin is the condensation product of an aldehyde with a compound, selected from the group comprising urea and / or melamine. Content of ethylene oxide in the composition is at least 1% by weight, based on 100% of the total weight, at least one isocyanate and at least one polyester.

EFFECT: use of the composition makes it possible to improve the miscibility of the combined amino resin / isocyanate mixtures, which leads to an improvement in the physicomechanical properties of the wood composites.
