    • A process for the production of a light lignocellulose-containing substance having an average density in the range from 200 to 600 kg/m3, in which, in each case based on the lignocellulose-containing substance:A) from 30 to 95% by weight of lignocellulose particles;B) from 1 to 25% by weight of expanded plastics particles having a bulk density in the range from 10 to 100 kg/m3;C) from 3 to 50% by weight of a binder selected from the group consisting of aminoplast resin, phenol-formaldehyde resin and organic isocyanate having at least two isocyanate groups and, if appropriateD) additivesare mixed and then pressed at elevated temperature and under elevated pressure, wherein the expanded plastics particles are obtained from expandable plastics particles by expansion and the expanded plastics particles thus obtained are further used without further intermediate steps for the production of the light lignocellulose-containing substance.
    • 一种用于生产平均密度为200-600kg / m 3的轻木质素纤维素物质的方法,其中在每种情况下基于含木素纤维素的物质:A)30至95重量% 的木质纤维素颗粒; B)1至25重量%的堆积密度在10至100kg / m 3范围内的发泡塑料颗粒; C)3至50重量%的选自氨基塑料树脂,酚醛树脂和具有至少两个异氰酸酯基团的有机异氰酸酯的粘合剂,如果合适的话,D)添加剂混合,然后在高温下压制, 在升高的压力下,其中通过膨胀从膨胀塑料颗粒获得发泡塑料颗粒,并且进一步使用由此获得的发泡塑料颗粒,而不需要进一步的中间步骤来生产含轻木质素纤维素的物质。
