摘要

Recycled thermosetting phenolic formaldehyde (RPF) resins were pulverized to micron-sized powders and successfully reused as an effective component by reactive-injecting with neat phenolic formaldehyde (PF) and/or trioxymethylene (TOX) to prepare regenerated phenolic formaldehyde (i.e., PFxRPFyw and PFxRPFywTOXz). Tensile strength (sigma(f)), impact strength (I-s), and density (rho) of PFxRPFyw and PFxRPFywTOXz specimens were reduced as RPF concentrations or average particle sizes increased. It is worth emphasizing that sigma(f), I-s, and rho of each reaction-injected PFxRPFywTOXz series having a fixed RPF concentration and average particle size improved to a maximum value, as TOX concentrations reached a corresponding optimal value. This is the first investigation to report that sigma(f) and I-s of proper regenerated PF/RPF/TOX specimens using = 20 wt % RPF waste were = 95% of those of the virgin reaction-injected PF. Possible reasons accounting for these improved mechanical properties were proposed based on results from their Fourier transform infrared analysis (FTIR). (c) 2019 Wiley Periodicals, Inc. J. Appl.
