An Investigation of Wood-Plastic Novolac Modified by Biomass Pyrolysis Oils

The possibility of using water insoluble fraction from biomass pyrolysis oil as additive in synthesis of Wood-Plastic novolac has been proved by using Differential Scanning Calorimetry (DSC) and Fourier Transformed Infra Red (FT-IR) spectroscopy. Synthesis of novolac with different concentrations (۱۰, ۲۰ and ۳۰ wt %) of water insoluble fraction were performed. It was found that mechanical properties were improved by using water insoluble fraction as additive. However, furthe increasing amount of water insoluble fraction, the mechanical properties of wood-plastic novolac were decreased. When the amount of water insoluble fraction in wood-plastic novolac was ۱۰%, the flexural strength of wood-plastic novolac was ۵۷.۸ MPa, tensile strength was ۲۹.۵ MPa. The performance and thermal behavior of novolac were characterized by DSC and TG.
