doi:10.7517/j.issn.1674-0475.2012.05.390

Abstract

Abstract: The changing of yellowing factor of UV-curing material was monitored. The samples were added in different types and different proportion of antioxidants during thermal aging process to study the anti-yellowing effects of antioxidants and the different anti-yellowing ability of antioxidants. The UV-Vis spectrum was used to meter the transmittance of samples. The result shows that the antioxidant can reduce the yellowing degree during thermal aging process. The anti-yellowing ability of antioxidant is relative with the anti-yellowing ability of the hydroxyl in the antioxidant. There are synergistic effects in Irganox-1010/Irgafos-168 and Irganox-1076/Irgafos-168, and they show a better anti-yellowing effect than single antioxidant.

Key words: UV-curing, thermal aging, antioxidant, yellowing factor, hydroxyl
