摘　　要：主要研究了水性UV木器涂料中消泡剂种类的筛选,不同消泡剂之间的复配,以及利用正交试验的方法确定消泡剂、润湿剂及增稠剂之间的最佳匹配含量。在筛选消泡剂种类时,确定了消泡剂D的消泡效果最好;在消泡剂之间的复配中,发现了消泡剂D与消泡剂B之间复配时,涂料的消泡性、缩孔、透明度等都达到了最优的状态;在消泡剂B、消泡剂D、润湿剂及增稠剂之间的正交试验时,影响UV木器涂料涂膜效果的主次顺序是:润湿剂>消泡剂D>增稠剂>消泡剂B。UV木器涂料的涂膜效果最优的组合为润湿剂为0.3%(质量分数,后同),增稠剂为0.6%,消泡剂D为0.2%和消泡剂B为0.1%。This paper mainly studies the selection of defoamers for waterborne UV wood coatings,the combination of different defoamers,and orthogonal experiments for determining the optimal content matching of defoamers,wetting agents,and thickeners.In the selection of defoamers,it was determined that defoamer D had the best defoaming effect;in the combination of defoamers,it was found that the combination of defoamer D and defoamer B resulted in the best overall performance in terms of defoaming,shrinkage cavities and transparency of the coatings;in the orthogonal experiment involving defoamer B,defoamer D,wetting agent and thickener,the order of influence on the effect of UV wood coatings film was:wetting agent>defoamer D>thickener>defoamer B.The optimal combination for the effect of UV wood coatings film was 0.3%wetting agent,0.6%thickener,0.2%defoamer D and 0.1%defoamer B.
