FIELD: wood working industry.
SUBSTANCE: group of inventions relates to production of boards from wood fibre. Board contains resin based on cross-linked polylactic acid and fibre. Wood fibre is present in the amount of 50-150 weight parts per 100 weight parts of resin based on cross-linked polylactic acid. Resin based on cross-linked polylactic acid is obtained by means of cross-linking initiated by heating or radiation. 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 the board.
