Physical and Mechanical Properties of Mediumdensity Fibreboards Using Soy-Lignin Adhesives

Emission of formaldehyde from wood-based composites is a serious concern for research. In this study, nine different combinations of soy�lignin-based adhesives were prepared by varying their pH and soy content. Lignin was extracted from rubberwood fibres by an enzymatic treatment. Physical and che...

description Emission of formaldehyde from wood-based composites is a serious concern for research. In this study, nine different combinations of soy�lignin-based adhesives were prepared by varying their pH and soy content. Lignin was extracted from rubberwood fibres by an enzymatic treatment. Physical and chemical properties of the soy�lignin adhesives were investigated. Solid content in soy�lignin adhesive was calculated by oven-dry method and viscosity was studied using a digital viscometer. Fourier transform infrared spectroscopy was performed to study the structural changes in treated lignin and modified soy�lignin adhesives. Medium-density fibreboard (MDF) was prepared using the nine different soy�lignin adhesives and its bending and internal bonding properties were tested. It was observed that wood composites prepared by alkali-treated soy�lignin adhesives had improved properties. Scanning electron microscope was used to study the surface morphology of MDF. All samples were tested according to ASTM D1037-06a standards. The boards prepared using alkali soy�lignin adhesives passed internal bonding and modulus of rupture tests.
