【摘要】 <正> 前文已经叙述羧酸稀土络合物的合成,本文介绍羧酸稀土络合物在涂料中的应用。我们对三大系列共几十个样品的催干作用进行了较系统深入的研究,初步确定了稀土络合物在涂料中不仅具有辅助催干剂作用,而且具有主催干剂作用,并确证了涂料品种与稀土络合物匹配的关系。除代替涂料中的铅催干剂外,还探索了更多还原

【Abstract】 Carboxylic rare earth complexes possesses not only the function of auxiliary catalyst driers but also those of active catalyst driers. Combining with Co catalyst drier, it may replace the toxic Pb catalyst drier as well as Mn, Zn, and Ca auxiliary catalyst driers in alkyd paints and improve the properties of gloss, hardness, adhesion. For example, it can replace a half or even the total amount of Co catalyst drier in alkyd lacquer C01-1 with good quality of the product. These complexes have also a good function of catalyst drier for the ester gum lacquer or colored paint.更多还原
