FIELD: wood working industry.
SUBSTANCE: group of inventions relates to woodwork, in particular to production of boards from wood flour. Board contains resin based on cross-linked polylactic acid and wood flour. Wood flour is present in amount of 50 to 150 weight parts per 100 weight parts of resin based on cross-linked polylactic acid. Resin based on cross-linked polylactic acid is obtained by heat-initiated or radiation-initiated cross-linking. Board is produced by high-temperature molding of composition with subsequent treatment. Obtained board is used to form multilayer flooring material.
EFFECT: higher water resistance of board.
