The Quality of PinuspinasterArBinenn Particleboards Using Natural Adhesive Made of Corn Starch, Tannin and Chitosan

Abstract

The development and optimization of a new, environment-friendly adhesive made from abundant and renewable cornstarch, tannin and chitosan is described in this study. At present, the production of wood composites mainly relies on petrochemical and formaldehyde-based adhesives such as phenol-formaldehyde (PF) resins and urea-formaldehyde (UF) resins. Natural adhesive is not only environmentally friendly but also less expensive as compared to other exterior binders used in wood composite industry. The objective of this study is to evaluate the quality of adhesive and particleboard produced. This research describes performances of natural adhesive obtained from cornstarch, tannin and chitosan (solid content, viscosity, gel time, pH and bond strength). Results describe physical properties of all particleboard production according to standard EN 323, 2004. Mechanical properties of particleboard did not fulfilled standard EN 312 for IB, MOR and MOE.
