Effects of Moulding Temperature on the Physical Properties of Wood-Based Moulding Bonded with Citric Acid

Development of natural adhesive that do not depend on fossil resources is very important for the future of wood-based materials. We recently found that citric acid can be used as a natural adhesive for wood-based mouldng. In this study, we investigated the effects of moulding temperature on the characterization of wood-based moulding bonded with citric acid. Wood powder obtained from Acacia mangium was mixed with 20 percent (by weight) citric acid, and the powder mixture was moulded at a temperature ranging from 140oC to 220oC. The press pressure and heating time were set at 4 MPa and 10 minutes, respectively. The bending properties were affected by the moulding temperature, and the moulding fabricated at 180oC showed excellent velues. The average impact strength of the moulding at 180oC was 1.1 kJ/m2. Water resistance increased with moulding temperature, and good resistance againts boiling water was achieved. Thermal properties were also repeated boiling treatment. Based on the results of Fourier transform infrared spectroscopy, ester linkages between wood and citric acid were confirmed, especially at high moulding temperatures.
