摘要： 采用氟碳树脂作为基料树脂、纳米 SiO₂和聚四氟乙烯作为功能性填料制备了纳米复合氟碳防覆冰涂料，重点讨论了不同基料树脂、不同纳米 SiO₂和聚四氟乙烯含量下，漆膜表面特性和微观结构对疏水性和防覆冰性能的影响。结果表明：纳米 SiO₂含量、聚四氟乙烯含量均为纯固态树脂的 25%时所制备的防覆冰漆膜水接触角达 128°，滚动角达到 6°，着冰力为 26. 1 N，同时还具有优异的耐候性、耐腐蚀性和耐液体介质性，能够满足多个工业领域对防覆冰的要求。

Abstract: Nano composite fluorocarbon anti-icing coatings was prepared by using fluorocarbon resin as the base resin，nano SiO₂ and polytetrafluoroethylene（PTFE） as functional fillers. The focus was on the influence of surface characteristics and microstructure of paint films on the hydrophobicity and anti-icing performance under different types of base resin，different contents of nano SiO₂ and PTFE. The results showed that the anti-icing coating film prepared with a nano SiO₂ content of 25% of the pure solid resin and a PTFE content of 25% of the pure solid resin had a water contact angle of 128 °，a rolling angle of 6 °，and an icing force of 26.1 N. It also had excellent weather resistance，corrosion resistance，and resistance to liquid media，which could meet the requirements of multiple industrial fields for anti-icing.
