초록
In this study, we fabricated high density polyethylene (HDPE) composites filled withantioxidants and UV stabilizers. The electron beam irradiation on the fabricated composites wascarried out over a range of absorbed doses from 50 to 200 kGy to confirm the changes of discoloration. The changes of discoloration were characterized using a color difference meter and FT-IRfor confirming the changes of the color difference and structural change. It was observed that thecolor difference of IRGANOX 1010-, IRGAFOS 168-, and TINUVIN 328- added HDPE was higherthan that of the control HDPE by electron beam irradiation. The melting temperature of UV stabilizer-added HDPE was not significantly changed by electron beam irradiation. However, the meltingtemperature of phenol-containing antioxidant-added HDPE was increased with increasing theabsorbed dose. And the melting temperature of phosphorus-containing antioxidant-added compositewas decreased with increasing the absorbed dose.
