The Effect of UV Light and Xenon Lamp on Anti-Aging Properties of Recycled Milk-Cartons/PE Composite Siding
The colour change and flextural properties of recycled milk-cartons/PE composite siding after tested in UV light accelerated aging champer and xenon lamp accelerated aging champer were studied. It showed that:(1)The ΔE value of samples in UV light champer was higher a little than it in xenon lamp champer after tested in later 1000h, which indicated UV light accelerated aging had more serious damage on material compared with xenon lamp accelerated aging; (2)The MOE of samples reduced 26.24%、39.82%、45.44% respectively after tested in UV light champer for 500h, 1000h, 1500h, with the MOR reducing 18.39%、19.01%、30.65%; while the MOE reduced 11.91%、29.60%、44.94% respectively after tested in xenon lamp champer for 500h, 1000h, 1500h, with the MOR reducing 8.53%、8.21%、26.02%, which showed that the effect on flextrual properties of UV light champer was greater than xenon lamp champer; (3) FTIR analysis showed it appeared carbonyl absorption peak on sample’s surface and methylene content increased a lot, which indicated polymer molecular chains had degraded into samll molecular chains.
