| 摘要 |
The invention relates to a method for producing lignocellulose materials by mixing A) lignocellulose-containing particles or fibers with B) organic isocyanate comprising at least two isocyanate groups or mixtures thereof, optionally with C) binders selected from among the group comprising phenol formaldehyde resins, aminoplast resins, protein-based binders, and other polymer-based binders or mixtures thereof, D) additives or mixtures thereof, E) plastic particles or mixtures thereof. In said method, in step i.) the obtained mixture is spread to form a mat, ii.) the mat is pre-compact and heated during or following the pre-compacting process, and iii.) then the mat is hot-pressed by applying an increased temperature in method step ii.) during and/or following the pre-compacting process, the obtained mat reaching a minimum value of 4 cm in the push-off test. |
