FIELD: chemistry.
SUBSTANCE: method involves depositing an adhesive system onto one or more pieces of wood-based material and joining one or more pieces with one or more additional pieces of the material. The adhesive system contains one component which contains starch, and another component which contains one or more polymers belonging to a group comprising polyvinyl amine, copolymers poly(vinyl alcohol-co-vinyl amine), poly(vinyl alcohol-co-vinyl formamide), polyallyl amine, polyethylene imine, polyamido amine and polyvinyl formamide. The two components are deposited on the wood-based material as unmixed separate components. The adhesive system further contains one or more polymers containing acetoacetylated polyvinyl alcohol.
EFFECT: use of the adhesive system enables to produce such wood-based products as boards based on chips, particles or fibres or boards based on aligned long chips.
