LIGNOCELLULOSE MATERIALS HAVING GOOD MECHANICAL PROPERTIES

摘要

A process for the production of a lignocellulose-containing substance having an average density in the range from more than 600 to 900 kg/m3, in which, in each case based on the lignocellulose-containing substance: A) from 30 to 95% by weight of lignocellulose particles; B) from 1 to 25% by weight of expanded plastics particles having a bulk density in the range from 10 to 100 kg/m3; C) from 3 to 50% by weight of a binder selected from the group consisting of aminoplast resin, phenol-formaldehyde resin and organic isocyanate having at least two isocyanate groups and, if appropriate D) additives, are mixed and then pressed at elevated temperature and under elevated pressure.
