中山大学化学系合成了一系列不同结构羧酸稀土盐,并对其在油漆中的催干性能进行系统的测试及筛选,同时对其催干机理进行了初步探讨。他们研制成功的环烷酸稀土油漆催干剂,去年通过了省级技术鉴定。该催化剂(即干料)是根据正交设计实 Sun Yat-sen University of Chemistry synthesized a series of different structures of rare earth carboxylate salts, and its drying performance in the paint system testing and screening, at the same time its drying mechanism was discussed. They successfully developed rare earth naphthenate driers, last year passed the provincial technical appraisal. The catalyst (ie, dry material) is based on orthogonal design
