Abstract

This paper reports on plywood glued by adhesives based on lignin-phenol-formaldehyde resins. Resin was obtained by polycondensation of sulphate lignin with phenol and formaldehyde in alkali medium. Sulphate lignin was separated from black liquor obtained by delignification of poplar and willow wood.

Zusammenfassung

Dieser Aufsatz berichtet über Sperrholz, das mit Klebstoffen auf der Basis Lignin-Phenol-Formaldehyd verleimt wurde. Das Harz wurde durch Polykondensation von Sulfatlignin mit Phenol und Formaldehyd in alkalischem Medium hergestellt. Das Sulfatlignin war aus Ablaugen nach der Delignifizierung von Pappel- und Weidenholz isoliert worden.
