合成工艺对热解油改性酚醛树脂老化性能影响
Effects of synthesis technology on aging performance of phenol-formaldehyde resin modified by bio-oil
摘要
Abstract
Bio-oil was added as a substitute of phenol for phenol-formaldehyde (PF) resin to enhance the toughness and water resistance, thus improving the aging performance. The effects of the substitute rate of bio-oil to phenol, addition of sodium hydroxide (NaOH) and reaction temperature on the aging performance of bio-oil phenol-formaldehyde (BPF) resin were examined using UV weathering. The variations on bonding strength of plywood and microstructure of cured resin were measured. The changes in the chemical structure of cured BPF resin were analyzed by the Fourier transform infrared spectroscopy (FTIR) and solid-state nuclear magnetic resonance (NMR) to understand the aging behavior of BPF resin.Results showed that the decrease rate of bonding strength of plywood and aging degree of cured resin were reduced with the increase of the substitute rate of bio-oil to phenol and reaction temperature. As the growing addition of NaOH, the decrease rate of bonding strength changed little, but the aging degree of cured resin decreased first then increased. After aging 960 h, the peak strength of methylene and ether bonds decreased, while the peak strength of aldehyde, ketone and carboxyl acids increased.关键词
