摘要

耐光性能是评价温致变色木材变色效果的重要指标之一,采用氙灯加速老化的方法,考察两种紫外线吸收剂（UV-531和UV-326）对温致变色木材耐光性能的影响。结果表明,两种紫外线吸收剂均可改善变色木材的耐光性能,以UV-326的改善效果更优。综合考虑成本、耐光性能等因素,UV-326的适宜添加量为1.6%。

Abstract

Light fastness is an important characteristic of thermochromic wood.The effects of type and dosage of ultraviolet absorber（UV-531 and UV-326）were selected for treating thermochromic wood.The results showed that both of the two ultraviolet absorbers could improve light fastness of the thermochromic wood.Different dosage of UVA had significant influence on the colorimetric parameters of thermochromic wood.UV-326 showed a better effect with optimum dosage of 1.6%.
