    摘要：通过超疏水涂层混凝土基本性能研究，得出表面接触角、冰层粘结力等是影响超疏水材料防冰效果的关键参数。通过结冰试验和疏冰试验对超疏水材料涂层性能进行分析。结果表明，超疏水材料涂层可以降低混凝土表面接触角，并进一步降低其结冰量，延长结冰时间，并降低冰层粘结力，从而有效改善混凝土的防覆冰性能。

    Abstract：Through the study of the basic properties of super hydrophobic coating concrete，it is concluded that the contact angle of the surface and the binding force of the ice sheet are the key parameters affecting the anti-icing effect of the super hydrophobic material. The properties of super hydrophobic coatings were analyzed by means of icing and deicing test. The results show that the super hydrophobic material coating can reduce the contact angle of the concrete surface，and further reduce the ice quality，prolong the freezing time and reduce the ice binding force. Super hydrophobic materials can effectively improve the anti-icing performance of concrete.
