Verleimung von Holzwerkstoffen mit Stärke-Tannin-Klebstoffen
Abstract
Besides synthetic adhesives natural binders can be used as a binding agent in particleboards. Within the framework of a research project the adhesive potential of starch-tannin adhesives was assessed. The results reveal: starches degradaded by acids or enzymatically can be used in combination with condensed tannins as adhesives in particleboards. The modified starches decrease the viscosity of the resin, increase its pot life and decrease its gelation time. Under defined boundary conditions particleboards of the type V100 and V20 can be made using a combination of tannin and starch.
