In this paper, the effect of the water-silicon ratio of the molecular sieve synthesis solution on the molecular sieve anticorrosive film during the preparation of the silicalite-1 molecular sieve membrane by the secondary growth method was studied. In order to enhance the bonding force between the foamed aluminum and the molecular sieve anticorrosive film, the silane coupling agent was used as the connection layer to study the film-forming effect and anticorrosive effect of the molecular sieve film when the water-silicon ratio was 100, 200, and 300. Scanning electron microscope and X-ray diffraction were used to analyze the morphology and composition of the anticorrosive film, and the corrosion resistance of the film was analyzed by electrochemical impedance spectroscopy. The results show that the surface of the silicalite-1 anticorrosive film prepared with a water-silicon ratio of 200: 1 is the most dense, and the crystallinity and anticorrosive performance are the best. On this basis, the film formation mechanism and anticorrosive mechanism of the silicalite-1 anticorrosive film on the surface of aluminum foam were analyzed.

本文研究了二次生长法制备silicalite-1分子筛膜时分子筛合成液水硅比对分子筛防腐蚀膜的影响。为了提高泡沫铝与分子筛防腐膜之间的结合力，以硅烷偶联剂为连接层，研究了水硅比为0时分子筛膜的成膜作用和防腐作用。 100、200和300。使用扫描电子显微镜和X射线衍射分析防腐蚀膜的形貌和组成，并通过电化学阻抗谱分析膜的耐腐蚀性。结果表明，水硅比为200：1制备的silicalite-1防腐膜的表面最致密，结晶度和防腐性能最佳。在此基础上，分析了泡沫铝表面上的silicalite-1防腐蚀膜的成膜机理和防腐蚀机理。
