摘要
对 5 0 0t/a中试装置生产的硅丙乳液进行了粒径、红外、DSC、TGA、NMR等结构表征 ,指导生产工艺优化。得到高性能硅丙乳液涂料 ,具有优异应用性能 ,人工老化试验通过 15 0 0h ,粉化 0级 ,变色 1级 ,耐沾污性 2 % ,耐洗刷性 10 0 0 0次 ,用于外墙装饰具有良好应用前景。
Structure characterization of silicone-acrylate emulsion made in 500t/a pilot unit are carried out by particle size analyzer,IR,DSC,TGA and NMR etc.for process optimization. A super exterior coating of silicone-acrylate emulsion with excellent weather resistance(over 1500h) , atomize 0 level,off-colour 1 level and antifouling performance 2%,washing resistance 10000 times is obtained .Wide application of this coating for decorating external wall is forcasted.
