Description
Technical Field

Background
Ice is a common form of water, the basic substance on earth, and many of the infrastructures in our lives are affected by ice. Ice formation and accumulation typically occurs on surfaces exposed to high humidity atmospheres, temperatures at or near zero, or in environments with high convective cooling rates. Freezing can lead to equipment handling difficulties, safety hazards, and high equipment maintenance costs. In various fields such as transportation, aerospace, power communication and the like, icing can bring great harm and potential safety hazard to human beings and the society. Mechanical deicing, heating deicing and chemical reagent spraying are effective, but have the problems of high energy consumption, environmental pollution and the like. Therefore, it is widely believed that the application of functional coatings with anti-icing properties and easy removal on the surface of the substrate is a necessary and effective method.
The anti-icing coating researched at home and abroad at present can be roughly divided into three categories from the anti-icing principle and factors influencing ice adhesion: 1. the sacrificial coating can slowly release the low-molecular-weight anti-icing agent and migrate to the surface of the coating in the use process, so that the coating has anti-icing performance; 2. various special surface treatment methods are used to form proper roughness on the surface of the base material, so that the base material has unique surface characteristics and super-hydrophobicity, and the technical route is only in an experimental research stage at present and is far away from practical application; 3. the resin containing fluorine and silicon and the auxiliary agent are used for preparing the low surface energy coating, so that the water absorption and the icing force are reduced, which is the feasible development direction at present. However, the existing anti-icing coating needs to be improved in component ratio and poor in performance, so that a high-iron solvent type anti-icing coating in a alpine region and a production method thereof are needed to overcome the problems.
