本发明涉及种在带锈青铜表面构筑超疏水膜的方法，主要目标是在不改变文物形貌的基础上，防止青铜器的进步腐蚀，包括如下步骤：(1)预处理；(2)通过气相缓蚀剂增加青铜表面活性基团；(3)进行硅烷化处理；(4)重复步骤(2)和(3)，获得具有超疏水性能的青铜表面。本发明通过气相层层自组装技术成功在带锈青铜表面构建无色透明超疏水薄膜，制备方法安全，对基体表面无损；采用本发明方法所构建的超疏水表面接触角为152°-158°，表现出良好的超疏水性能，可实现青铜文物表面的防腐和自清洁；采用本发明方法所制备的超疏水表面具有很高的稳定性和耐久性，在强腐蚀性溶液中浸泡90天后，仍然表现出良好的防腐性能。 The invention relates to a method for constructing a super-hydrophobic film on a rusty bronze surface. The method mainly aims at preventing further corrosion of bronze ware on the basis that the appearance of a cultural relic is not changed. The method includes the following steps: (1) pretreatment is carried out; (2) active groups on the bronze surface are increased through a volatile corrosion inhibitor; (3) silanization treatment is carried out; and (4) the step (2) and the step (3) are repeatedly executed, and the bronze surface with the super-hydrophobic performance is obtained. According to the method, the colorless and transparent super-hydrophobic film is successfully constructed on the rusty bronze surface thro
