Method of manufacturing a fiberboard

Abstract

The invention relates to a method for manufacturing a water-resistant fiberboard including lignocellulosic fibers and binders. In order to provide a cost-effective, water-resistant fiberboard, the following steps are provided: providing lignocellulosic fibers, providing the binder, providing an elasticizing additive, applying the binder and the elasticizing additive, forming the fiber cake from the fibers provided with binder and elasticizing additive, pressing the fiber cake in a press while curing of the binder to manufacture a fiberboard, wherein 15 wt. % to 35 wt. % melamine resin, phenolic resin, mixtures and mixed condensates thereof or guanamine resin and 5 wt. % to 20 wt. % urea resin as binders as well as 0.1 wt. % to 7 wt. % of the elasticizing additive, in each case based on the total weight of the fiberboard (atro), are used. The invention further includes a water-resistant fiberboard.
