С целью повышения экологической безопасности производства древесноволокнистого плитного (ДВП) материала при одновременном повышении экологической безопасности, физико-механических показателей и водостойкости ДВП, содержащий древесное волокно и связующее на основе гидролизного лигнина, в качестве связующего материал содержит аддукт окисленного в присутствии органического растворителя гидролизного лигнина и аммиака при следующем соотношении компонентов, мас. %: древесное волокно 9 - 99, аддукт окисленного в присутствии органического растворителя гидролизного лигнина и аммиака 1 - 10. При этом в аддукте используют лигнин, полученный окислением гидролизного лигнина молекулярным кислородом или воздухом в среде водного раствора органического растворителя, преимущественно в среде водного раствора ацетона. Согласно способу получения связующего окисление гидролизного лигнина молекулярным кислородом или воздухом осуществляют в среде водного раствора органического растворителя, после чего выделяют окисленный лигнин из раствора, а затем растворяют окисленный лигнин в водном растворе аммиака.In order to increase the environmental safety of the production of wood-fiber board (fiberboard) material while improving environmental safety, physical and mechanical properties, and water resistance, fiberboard containing wood fiber and a binder based on hydrolytic lignin contains an adduct of hydrolysis lignin oxidized in the presence of an organic solvent as a binder and ammonia in the following ratio, wt. %: wood fiber 9–99, adduct of hydrolyzed lignin and ammonia 1–10 oxidized in the presence of an organic solvent. In this adduct, lignin obtained by oxidizing hydrolyzed lignin with molecular oxygen or air in an aqueous solution of an organic solvent, mainly in an aqueous solution of acetone, is used. . According to a method for producing a binder, the oxidation of hydrolysis lignin with molecular oxygen or air is carried out in an aqueous solution of an organic solvent, after which oxidized lignin is isolated from the solution, and then the oxidized lignin is dissolved in aqueous ammonia.
