光稳定剂对木粉/回收聚乙烯复合材料老化性能的影响
Effects of Photo Stabilizers on Aging Properties of WPC
摘要
Abstract
The effect of commonly used photo stabilizers on ageing resistance of wood plastic composites were investigated by analyzing the properties of WPC before and after accelerated weathering with added 6 different photo stabilizers. The results showed that photo stabilizers could effectively increase the ageing resistance ability of WPC, and reduce the mechanical properties during the aging process. The effect of different photo stabilizers on the de-crease of WPC modulus of rupture have obvious difference during the aging process, hindered amine and benzophe-none have greater effect than azimino-benzene. The effect of different photo stabilizers on the increase of water ab-sorption rate of WPC also have significant difference during the aging process, the best was hindered amine, fol-lowed by benzophenon, and the worst was azimino-benzene. The effect of different photo stabilizers on the change of chromatic aberration showed no obvious differences.关键词
