摘要
PVDF粉末涂料具有优异的耐候性能,被广泛应用于建筑物外墙等需要保持长久耐候性的场所。如何使涂膜长久附着于基材表面成为了工业界及学术界广泛关注的问题。在PVDF粉末涂料中添加含有不同有机官能团的附着力促进剂(N1、N2、N3、N4以及N5),研究有机基团对涂膜附着力的影响,进一步探讨提高涂膜附着力的方法。研究表明,在5种助剂中,N3对涂膜附着力的提高最为有效。
Due to the excellent weather resistance ability,PVDF powder coating had been widely applied in architectural external wall that should be kept long- term weatherability. How to make coating film adhere to the matrix surface for a long time became the focus of industry and academe. This research reported the effect of different adhesion promoter（ N1,N2,N3,N4 and N5） in PVDF powder coating. The method of promoting adhesion was further discussed. It indicated that N3 was the most effective adhesion promoter among five additives.
