Abstract

Wood composites are susceptible to fire. Therefore research projects were carried out to investigate the potential of bentonite nanoparticles in improving fire-retarding properties of medium-density fiberboards (MDF). The objective of the present study aimed to determine the effects of nanobentonite on physical and MECHANICAL PROPERTIES of MDF. Ten percent ureaformaldehyde resin was used to manufacture MDF. Nano bentonite at 5 levels (%0, %5, %10, %15 and %20 of the dry weight of the fibers was sprayed on the fibers after being mixed with the resin solution. Mats were hot-pressed for 4, 5, and 6 minutes at temperature of 170oC. Density was kept constant (75 g.cm-3) for all treatment. Results revealed that nano Bentonite did not improve the physical and MECHANICAL PROPERTIES. The lowest adverse effect of nano Bentonite consumption on the PHYSICAL PROPERTIES (water absorption, thickness swelling) was observed at %5 and the treatment with 5% and %10 nano bentonite showed less negative effect on the MECHANICAL PROPERTIES (Modulus of rupture, Internal Bonding). Treatment with 20% is not recommended because it deteriorated the properties of the MDF and the surface of fiberboards was not suitable. It is concluded that due to the fire-retarding improvement, %5 of nano Bentonite is recommended as the optimum level for industrial application.
