摘要

Several million tons of waste tyres are generated every year all over the world. Many researches have been conducted on the use of recycled tyre products in the industrial area including chemical feedstock. In this study, the bonding performance of commercial phenol-formaldehyde (PF) adhesive containing different amounts of waste tyre pyrolytic oil (10-40 wt%) was investigated. The chemical structure of the waste tyre pyrolytic oil was analysed using Fourier transform infrared spectroscopy (FT-IR). The effect of the substitution level of the tyres pyrolytic oil on the physical characteristics of the PF adhesive was determined. In addition, the shear strength of single lap-joint wood samples bonded with the blended PF adhesives was determined for indoor and outdoor conditions. It was found that the solid content of the blended PF adhesives decreased with increasing amount of the pyrolytic oil. The bonding performance of the wood samples bonded with the PF adhesives containing up to 20 wt% pyrolytic oil were about the same as that of commercial PF adhesive. Finally, pyrolytic oil could be partially blended with commercial PF adhesive.
