Production of chip- or fiber-board by pressing and optionally heating wood particles uses a 2-component crosslinkable thermoplastic binder comprising copolymers containing 0.1-50 wt.% units containing carboxyl, OH or NH groups, and compounds containing ≥ 2 epoxy, N-methylol, NCO and/or ethylene carbonate groups which react with the carboxyl, OH or NH groups of (A). Production of chip- or fiber-board by pressing and optionally heating wood particles uses a 2-component crosslinkable thermoplastic binder comprising: (A) copolymers containing 0.1-50 wt.% units containing carboxyl, OH or NH groups, the copolymer being based on vinyl esters of 1-18C alkylcarboxylic acids, (meth)acrylates of 1-15C alcohols, dienes, olefins, vinyl aromatics or vinyl halides; and (B) compounds containing ≥ 2 epoxy, N-methylol, NCO and/or ethylene carbonate groups which react with the carboxyl, OH or NH groups of (A). |
