玻璃粉的突出优点及在涂料中的应用

Release date:2018-05-07  source:粉体网  Browse times:661
       玻璃粉是一种易打磨抗划高透明粉料,粒径小、分散性好、透明度高、防沉效果较好;经过多次表面改进,具有良好的亲和能力,并且有较强的位阻能力,能方便地分散于涂料中,成膜后可增加涂料丰满度,制成的水晶透明底漆类,既保持清漆的透明度,又提供良好的打磨性。主要用于生产高档家俱时作水晶底漆用。也广泛用作装修用底面两用漆。适用范围:聚脂漆、聚氨脂漆、硝基漆、醇酸漆、丙烯酸漆、乙烯酸漆等,PE透明底漆等。

玻璃粉有几个突出的优点:

1、玻璃粉透明度好、硬度高、粒径分布均匀

2、玻璃粉分散性好,与树脂和油漆体系中的其他成分相溶性佳

3、玻璃粉经多次表面处理,在油漆体系中作填充,漆膜不带蓝光,重涂性好

4、用在高档耐刮伤面漆中,可增加面漆的硬度、韧度,提高漆膜的抗刮伤性能,具有消光作用,可提高漆膜的耐候性

5、同比滑石粉,玻璃粉在油漆开稀后较易沉淀,故防沉措施应适当加强。
