The present invention relates to a process for the production of lignocellulose materials via mixing
A) of lignocellulose-containing particles or fibers,B) with organic isocyanate having at least two isocyanate groups or a mixture of these, and optionally withC) binders selected from the group of the phenol-formaldehyde resins, the aminoplastic resins, the protein-based binders, and other polymer-based binders, and mixtures of these,D) additives or a mixture of these, andE) plastics particles or a mixture of these, with the steps of:i.) scattering of the resultant mixture to give a mat,ii.) precompaction and heating of the mat during or after the precompaction process, andiii.) then hot pressing,
wherein, in the step ii.), operations are carried out at elevated temperature during and/or after the precompaction process, and a value of at least 4 cm is achieved for the resultant mat in the push-off test. |
