Lignocellulosic material which has a Nucleus and two Outer layers, where the core comprises 30 to 98 by weight of Lignocellulosic particles, 1 to 25 of expanded Plastics particles and 1 to 50 of one or more layers and external binders, 70 to 99 of Lignocellulosic Fibers and 1 to 30 u No More Binders and process to produce it.

摘要

The present invention relates to lignocellulosic materials having a core and two outer layers, comprising in the core A)30% to 98% by weight of lignocellulose particles; B) 1% to 25% by weight of expanded plastics particles having a bulk density in the range from 10 to 150 kg/m3, C) 1% to 50% by weight of one or more binders selected from the group consisting of phenoplast resin, aminoplast resin, and organic isocyanate having at least two isocyanate groups, and D) 0% to 30% by weight of additives and in the outer layers E)70% to 99% by weight of lignocellulose fibers, F) 1% to 30% by weight of one or more binders selected from the group consisting of phenoplast resin, aminoplast resin, and organic isocyanate having at least two isocyanate groups, and G) 0% to 30% by weight of additives.
