Nano-Silica/Urea-Formaldehyde Resin-Modified Fast-Growing Lumber Performance Study

To promote the performance of fast-growing poplar wood for furniture applications, this study proposes and investigates feasibility modifying with a urea-formaldehyde resin impregnating agent by adding nano-SiO2 as way to improve its physical mechanical properties. By observing solubility addition in resin, determine optimal ratio solid content solution. After specimens were treated nano-SiO2/UF water absorption, wet swelling, dry shrinkage, nail grip, flexural strength, modulus elasticity compared analyzed effect impregnation modification ratio. The results showed that properties significantly improved SiO2, was beneficial reducing swelling shrinkage wood, increasing dimensional stability, grip increase strength concentration.
