Abstract

Flat pressed wood plastic composites were produced on a laboratory-scale using residues of lightweight foam core particleboards as raw material. Raw material preparation methods (dry blending and compounding with a twin screw extruder) and the wood flour content (WF) loading, as influencing parameters on the panel properties, were varied, and coupling agents (CA) were added in some variations. The results showed that panels produced with lower WF content (75 %) have better physical and mechanical properties compared to those of higher WF. The CAs only influenced the panel properties when they were added during the compounding of the materials. Due to the assumed higher wood degradation resulting from raw material compounding, the panel properties were inferior to the panels produced with dry blended materials.

Flachgepresste Holz-Polymer-Verbundwerkstoffe aus Produktionsabfällen von Spanplatten mit Schaumkern

Zusammenfassung

Produktionsabfälle von Leichtbau-Spanplatten mit Schaumkern wurden im Labormaßstab zu flachgepressten Holz-Polymer-Verbundwerkstoffe (WPC) weiterverarbeitet. Als Einflussparameter auf die Platteneigenschaften wurden die weitere Aufbereitung nach dem Zermahlen der Abfälle (Trockenmisch- und Doppelschnecken-Extruder-Verfahren) sowie der Holzanteil variiert. Einigen Varianten wurde Haftvermittler (CA) zugesetzt. Die Platten mit einem niedrigen Holzanteil (75 %) zeigten die besseren physikalischen und mechanischen Eigenschaften. Der Zusatz von Haftvermittler hat sich auf die Platteneigenschaften nur positiv ausgewirkt, wenn dieser vor dem Compoundieren zugegeben wurde. Aufgrund der thermischen und mechanischen Beanspruchung der Holzsubstanz im Extruder waren die Eigenschaften von Platten aus Trockenmischungen denen aus compoundierten Rohmaterialien überlegen.
