| 摘 要： | 为了制备一种疏水抗覆冰涂料,采用种子半连续乳液聚合法,通过添加乙烯基三乙氧基硅烷(A-151)和纳米二氧化硅粉末,分别合成了纯丙乳液、硅丙乳液和纳米二氧化硅/硅丙复合乳液,并将乳液涂覆在铝片表面,室温干燥成膜.利用红外光谱、粒度分析、扫描电镜等测试手段对3种乳液及其涂膜性能进行表征.结果表明:添加A-151可以使涂膜交联度提高到95%,吸水率降低到5%；添加纳米二氧化硅,可提高乳液涂膜的热分解温度,使乳液粒径大小分布均匀.此方法中,A-151和纳米二氧化硅改性的乳液涂膜疏水作用有限,仅使接触角增加到约30°.

| Abstract: | A hydrophobic anti-icing coating was prepared with pure acrylic emulsion,silicon-acrylate emulsion and nano-silica/silicone-acrylate composite emulsion respectively,which were prepared by the semi-continuous emulsion polymerization process,with addition of vinyl triethoxye silane(A-151) and nauosilica powder.Films were prepared these emulsion applied on the surface of aluminum sheet separately and dried at room temperature.The structure of these three kind of emulsions and films were charactered by FT-IR,pa... |
