摘　　要：为了给桑枝重组方材透明涂饰工艺提供基础数据,采用硝基清底漆和聚酯清底漆涂饰,研究不同砂光处理对桑枝重组方材表面漆膜附着力的影响;系统测试经2种清底漆涂饰后桑枝重组方材表面色度学和光泽度参数的变化。结果表明：桑枝重组方材经过120#~400#的砂纸砂光处理后,2种清底漆涂饰后漆膜附着力均在2级以上;涂饰前后桑枝重组方材色度学特征的变化是渐变过程,与涂饰次数有关,第1遍涂饰对方材色度学参数的影响最为显著;桑枝重组方材经2种清底漆涂饰后光泽度均得到明显的提高,经聚酯清底漆涂饰后光泽度高于硝基清底漆涂饰,经2种清底漆涂饰3遍后,桑枝重组方材原有平行于纤维束和垂直于纤维束方向的光泽度差异几乎消失。研究结果为桑枝重组方材在产品包装、家具以及装饰等领域的高附加值应用提供了技术依据。In order to provide basic data for clear painting process of reconstituted square lumber made from mulberry branches, the effects of different sanding processes on painting film adhesion were studied by using nitrocellulose transparent primer and polyester transparent primer. The changes of painting chroma- ticity and glossiness parameter were also studied in the paper. The results showed that painting film adhe- sions painted with two types of primer were all above 2 level after sanding with 120# ~400 # sand papers. The change of painting chromaticity was a gradual process,which was concerned with painting times. The first time painting had the most significant impact on painting chromaticity. Glossiness improved signifi- cantly after painting with two types of primer. The glossiness painting with polyester transparent primer was higher than that painting with nitrocellulose transparent primer. Glossiness difference almost disap- peared between parallel and vertical to the fiber bundle direction after 3 times painting with two types of primer. The results would provide technical basis for high value-added applications in product packaging, furniture and decoration, and other areas for reconstituted square lumber made from mulberry branches.
