Improved properties of particleboards produced with urea formaldehyde adhesive containing nanofibrillated cellulose and titanium dioxide

Urea-formaldehyde is one of the commonly used resin types in particleboard industry. In this study, effect nanofibrillated cellulose (NFC) and titanium dioxide (TiO2) addition formulation urea formaldehyde on physical, mechanical, morphological properties samples was investigated. The NFC (0.5% 1%) TiO2 (0.5%, 1%, 2%) were added to 10% adhesive formulation. Two different pressure times, 4 8 min, applied during production samples. Subsequently, water absorption (WA), thickness swelling (TS), internal bonding strength (IB), modulus rupture (MOR), elasticity (MOE), scanning electron microscopy (SEM), statistical analysis test determined. values ranged from 19.9% 34.9% WA 74.50% 110.6%. However, maximum MOR, MOE, IB 22.2 MPa, 2570 1.1 respectively.
