Abstract

In this research work effect of embedment of multiwall carbon nanotubes (MWCNTs) on the physical and mechanical properties of medium density fiberboard (MDF) have been investigated. The MWCNTs were embedded in urea formaldehyde resin (UF) at 0, 1.5%, 3% and 5% concentrations by weight for the manufacturing of nano-MDF. The addition of these nanoparticles enhanced thermal conductivity by 24.2% reduced curing time by 20% and controlled formaldehyde emission by 59.4%. The internal bonding (I.B), modulus elasticity (MOE), modulus of rupture (MOR), thickness swelling (Ts) and water absorption (WA) properties were improved significantly by 21.15%, 30.2%, 28.3%, 44.8% and 29% respectively as compared to controlled MDF.

摘要

在这项研究工作中，研究了多壁碳纳米管（MWCNTs）的嵌入对中密度纤维板（MDF）物理和力学性能的影响。通过将MWCNTs以0%、1.5%、3%和5%的重量浓度嵌入脲醛树脂（UF）中来制造纳米MDF。这些纳米颗粒的添加使热导率提高了24.2%，固化时间缩短了20%，并使甲醛释放量降低了59.4%。与对照MDF相比，内部结合强度（I.B）、弹性模量（MOE）、抗弯强度（MOR）、厚度膨胀率（Ts）和吸水率（WA）性能分别显著提高了21.15%、30.2%、28.3%、44.8%和29%。
