Abstract EN
The pure polyester polyurethane (TPU) film and the modified TPU (M-TPU) film containing 2.0 wt.% inorganic UV absorbers mixture (nano-ZnO/CeO2 with weight ratio of 3 : 2) and 0.5 wt.% organic UV absorbers mixture (UV-531/UV-327 with weight ratio of 1 : 1) were prepared by spin-coating technique.
The accelerated aging tests of the films exposed to constant UV radiation of 400 ± 20 µW/cm2 (313 nm) with an ozone atmosphere of 100 ± 2 ppm were carried out by using a self-designed aging equipment at ambient temperature and relative humidity of 20%.
The aging resistance properties of the films were evaluated by UV-Vis spectra, Fourier transform infrared spectra (FT-IR), photooxidation index, and carbonyl index analysis.
The results show that the composite UV absorber has better protection for TPU system, which reduces distinctly the degradation of TPU film.
O3/UV aging of the films increases with incremental exposure time.
PI and CI of TPU and M-TPU films increase with increasing exposure time, respectively.
PI and CI of M-TPU films are much lower than that of TPU film after the same time of exposure, respectively.
Distinct synergistic aging effect exists between ozone aging and UV aging when PI and CI are used as evaluation index, respectively.
Of course, the formula of these additives needs further improvement for industrial application.
