减少白本色漆人工老化失光率的途径

Route to Reduce the Artificial Aging Gloss Loss Rate of Origi-nal White Coatings

选用纳米钛白粉、光稳定剂、封闭聚氨酯、三胺树脂直接加入到白本色漆中,并与空白样(原漆)进行Q-U-V人工老化失光率对比,分析了失光率变化的规律,指出了降低白本色漆失光率的有效途径。

The gloss loss rate of original white coatings with nano titanium white powder, light stabilizer, blocked PU and triamine resin directly added in is compared with the gloss loss rate of the black sample in Q-U-V artificial aging. The changing discipline of gloss loss rates is analyzed and the effective route to reduce gloss loss rate is pointed out.
