Emulsifiers with high chemical resistance: a key to high performance waterborne coatings 总被引:4,自引:0,他引:4
Volker Duecoffre Wolfgang Diener Carmen Flosbach Walter Schubert 《Progress in Organic Coatings》1997,34(1-4):200-205
A powerful way to coatings with low volatile content are waterborne systems. They are an important alternative to high solid- and powder coatings. It is essential, that waterborne coatings should not have a lower property level compared with conventional systems. A novel type of emulsifier allows the preparation of non-ionic stabilized aqueous emulsions. The main advantage of this new type of emulsifier consists in improving the chemical resistance of the resulting crosslinked films, especially against acids. There upon they show no discoloring even at high staving temperatures and a very good emulsifying behavior. The base type can be easily functionalized with a multitude of chemical functionalities like -OH, -COOH or vinyl groups. That means the emulsifier can be incorporated in the film during the crosslinking reaction. A migration to the coating surface can be avoided under these conditions. The different synthesis routes will be described in detail. A comparison of three non-ionic stabilized waterborne automotive coating systems with different crosslinking reactions (polyurethane, transetherifying and nucleophilic addition) with the corresponding ionic stabilized systems shows the extraordinary quality of the new tones of emulsifiers. 相似文献

基于可持续发展和绿色环保的要求,以水替代有机挥发性溶剂的新型水性超疏水涂层逐渐成为研究热点,但是水性涂料的分散性及涂层的疏水稳定性、涂层性能等相关问题也随之而来。本文介绍了水性超疏水涂层制备方法的发展现状,针对水性超疏水涂层力学耐久性能差的问题提出可行性方案,例如制备内外一致的一体化复合结构,加强涂层内界面相互作用,交联作用或设计自修复水性超疏水涂层等。此外,还对水性超疏水涂层在油水分离、防结冰、自清洁等领域的进展进行阐述,并探讨了水性超疏水涂层的规模化制备、涂层力学性能的强化和耐久性研究将成为主要探索方向,只有夯实水性超疏水涂层的基础研究,工业应用才能突破。 相似文献

In this paper, a polymeric coating based on the modified chlorinated polypropylene (CPP) emulsion was synthesized, methyl methacrylate (MMA), butyl acrylate (BA) and acrylic acid (AA) were grafted onto CPP backbone and phase inversion was conducted to obtain waterborne emulsion. Results showed that the concentration of initiator (BPO) had the greatest effect on graft copolymerization. The concentration of emulsifier and temperature influenced the results of phase inversion. Besides, the thermal performances of modified CPP were better than untreated one. In addition, the coating obtained in optimum condition had excellent adhesion to BOPP film, and apparently improved the printing quality of the film. The printability promotion should be attributed to the different movement trend of coating’s polar and un-polar chains during the baking step, as well as the subsequent formations of new coating/substrate and coating/ink interface layer. 相似文献
