FIELD: chemistry.
SUBSTANCE: invention discloses a composition Binder for lignocellulosic material or mineral fibres, which contains an organic polyisocyanate obtained from diphenylmethane diisocyanate (MDI) and/or their oligomers, compound, reactive for isocyanate, representing an aromatic compound oligoetherpolyol, water and an alkali metal salt of carboxylic acid as catalyst accelerating isocyanate trimerization. Invention also discloses a method of producing Binder composition, method of producing bound mineral fibre product and method of producing bound lignocellulose product. Also described is a product of mineral fibre.
EFFECT: technical result consists in obtaining finished material with improved resistance and/or strength.
