Abstract

Radiation can make polymer materials change color and affect many polymer materials radiation processing of the application, so an exploratory examination of the irradiation resistance of polymer materials has a certain significance. This paper through the blending of three light stabilizer 770, 622, 944, with PP, the yellow index, mechanical properties, scanning electron microscopy, thermal performance are analyzed, It can draw a conclusion that light stabilizer 770 has an good irradiation resistant color for PP, in particular when the phr is 0.5, the yellowness index is better than others; light stabilizer though changed the performance of mechanics of materials, but the material is still in the range of application before and after irradiation; light stabilizer makes the material crystallinity increase; epitaxy initial decomposition temperature have different degree of change.
