Abstract
Three kinds of bio-oil-phenol-formaldehyde (BPF) resins were prepared which contained 30 wt% replacement of phenol with bio-oil derived from poplar, larch and bamboo. Main component of different pyrolysis bio-oil, physical properties of different BPF resins and their plywood specimens were investigated. The results show that phenolics in bio-oil derived from poplar, larch and bamboo are 13.8653%, 14.7529% and 10.3987%. All the experimental BPF resins have similar physical properties, which comply with GB/T 14732-2006. The performance of the plywood specimens bonded with different BPF resins were larch-BPF > poplar-BPF > bamboo-BPF, all of which could achieve the demands of GB/T 9846-2004.
