Abstract
This is the second in a series of reports on the evaluation of weathering durability of waterborne preservative treated wood by accelerated weathering. The leaching of copper from ACQ-, CCA-, and CuAz-treated samples during weathering was increased by UV irradiation, when compared between full weathering and water-only weathering. The FTIR spectra of the weathered ACQ-, CCA, CuAz-treated samples at 1731 cm-1, 1625 cm-1, 1510 cm-1, which are related to the fixation of copper, were different from those of unweathered controls. This result means that UV irradiation can weaken the chemical bond between lignin and copper and/or extraction of lignin-copper complex can be occured when lignin erode away by weathering.
