摘要

以直接涂刷涂料与覆膜两种方式,涂饰杨木和樟子松单板,并对涂饰后的单板进行进行氙光辐射试验,分析其光变色规律和光变色度的差异。结果表明:直接涂饰与覆膜的单板受光辐射时均发生变色,且光变色规律基本一致;直接涂饰单板的总色差值（ΔEa*b）大于覆膜单板,说明利用覆膜的方法研究涂饰单板的光变色是可行的。

Abstract

The authors of this paper conducted an experiment to investigate discoloration of polyurethane and acrylic coated veneers to improve the lightfastness of paint coated wood.Scots pine and poplar veneers were selected and coated by two methods（direct painting and covering with a coated film）.The coated veneers were exposed under a Xenon-lamp attenuation instrument for an accelerated test.The results showed the color change trend of coated veneers of both species was similar.However,the aberration of the paint coated veneer was higher than that of the veneers covered with coated films.
