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 with C) 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, and E) 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, and iii.) 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.

The present disclosure discloses a high-temperature fast-curing starch-based adhesive for particleboards and a preparation method thereof, belonging to the technical field of adhesive preparation. The low viscosity of the starch-based adhesive is ensured by selecting a crosslinking monomer which does not self-crosslink in a reaction process in the present disclosure, and a binary crosslinking agent matched with the crosslinking monomer is added before use to be quickly crosslinked with the crosslinking monomer at high temperature so as to ensure better thermosetting property and water resistance as well as faster curing speed of the starch-based adhesive at the same time, which meets the requirements of the particleboards for the adhesive, solves the problem of long curing time of the existing starch-based adhesives at high temperatures, further shortens the curing time of the starch-based adhesives to about 60 s, and improves the production efficiency of the particleboards.
