Abstract

A compound of lignocellulose material mixed with a binder is hot-pressed. The binder used is an aqueous emulsion of organic polyisocyanate. This emulsion contains a nonionic surfactant that is free of hydroxyl, amino and carboxyl groups. The emulsions have a polyisocyanate content of up to 65%. The hot pressing can take place at temperatures as low as below 100 DEG C. The process is used with reference to producing board, for example chipboard.
