摘　　要：通过对不同表面粗糙度光皮桦涂饰性能的比较分析,结果表明,光皮桦的表面粗糙度值随着砂纸粒度的减小而减小。不同表面粗糙度的光皮桦经醇酸清漆涂饰后其各颜色参数表现为:明度均有不同程度的降低,红绿轴色品指数和黄蓝轴色品指数表现为增大。涂饰后光皮桦的表面光泽度均有大幅度的提高;其表面漆膜失重量随着表面粗糙度的增大呈先减小后增大的趋势,表面漆膜附着力均为一级。SEM观察表明,适宜的表面粗糙度才有利于漆膜与光皮桦木材的结合。Painting properties of Betula luminifera timber with different surface roughness was analyzed comparatively. The results showed that surface roughness value of the timber decreased with the decrease of the granularity of the sandpaper. The variations of color parameters of the timber with different surface roughness after being painted with alkyd resin varnish were as follows： the lightness vale （L＊） decreased in varying degrees, indices such as ＂a＊ ＂ and ＂b＊ ＂ increased, surface brightness increased magnificently, weight loss of the paint film decreased firstly and then increased with the increase of the surface rough- ness. Adhesion of paint film was in first-grade. Observation of SEM showed that the optimal surface roughness was favorable to the adhesion of the film to the timber.
