水性高透明度哑光清面漆的制备

Preparation of Waterborne Matt Clear Finish with High Transparency

以水性乳液、消光粉和其他助剂为原料,通过配方优化设计,制备了一种高透明度的水性哑光清面漆。探讨了乳液、消光粉、分散剂、消泡剂的种类对最终研制的水性哑光(3分光)清面漆透明度的影响,采用目测和色差仪测试相结合的方法对涂膜透明度进行了评价。结果表明:当配方采用嘉宝莉乳液HG-4809、消光粉采用OK-607、分散剂采用快易分散剂、消泡剂采用Tego-810时,最终得到的哑光清面漆的涂膜透明度最佳,在标准黑色底板上的色差仅为0.17%。

Waterborne matt clear finish with high transparency was prepared by waterborne emulsion, matting powder and other additives on the basis of optimizing formaula design. The effects of variety of emulsion, matting powder, dispersant and defoamer on the transparency of waterborne matt clear finish were investigated; the transparency of films was evaluated by the cornbination of visual observation and colorimeter test. The results indicated that waterborne matt clear finish achieved the optimal transparency and △E＊ was 0.17% on the standard black wooden substrate when HG-4809 used as main film forming substance, OK-607 as matting agent, Orotan KUAIYI as dispersant, Tego-810 as defoamer.
