摘　　要：应用直接印刷技术处理压缩杨木,可增强杨木表面的装饰性。为解决印刷工艺中出现的漆膜附着力差的问题,试验探究了增强漆膜附着力的底漆改进工艺及白色底漆遮盖木纹工艺。结果表明:采用水性底漆和UV附着底漆相结合的工艺,同时在白色底漆遮盖木纹前,增加一道UV韧性底漆,可保证产品漆膜附着力等级不降低,按照GB/T 4893.4—2013《家具表面漆膜理化性能试验第4部分:附着力交叉切割测定法》检测,达到LY/T 1986—2011《直接印刷木地板》中规定的2级以上的技术要求。The surface decoration of Compressed Poplar can be adorned through direct printing technology.The study was conducted on improving the process of adhesive primer and the process of white primer covering wood grain to elevate the reduction of adhesive force level during the printing process.The results showed that the combined technique of waterborne primer and UV adhesive primer,and applying a UV tough primer prior to covering wood grain with white primer can ensure the adhesion level is not reduced.The adhesion force reached the 2nd grade or above of LY/T 1986—2011“Printed wooden flooring”in accordance with National standard GB/T 4893.4—2013“Test of surface coatings of furniture-part 4:Determination of adhesion-Cross cut”.
