摘　　要：防覆冰现已成为飞机结构、输电线路、制冷器械等设备上亟待解决的问题。对自主研发的三种疏水/超疏水复合涂层的防覆冰特性进行了综合对比研究,重点分析了各涂层在机械耐久性及超低温条件下除冰性的优势。测试结果表明:底漆-面漆复合超疏水涂层具备较优异的机械耐久性,在磨耗仪250 g载荷下磨耗40次后及冻融循环100次后冰剪切强度均小于30 kPa;而疏水纳米颗粒-润滑脂复合涂层超低温-150℃下的除冰性能表现优异,其初始冰层剪切力仅为11.5 kPa。本文研究成果将为疏水/超疏水涂层在防覆冰领域的应用提供有益的理论和实际指导。Anti-icing has now become an urgent problem to be solved in the fields of aircraft structure,power transmission lines,and refrigeration equipment.This paper conducted a comprehensive comparative study on the antiicing characteristics of three independently developed hydrophobic/superhydrophobic composite coatings,focusing on the analysis of the advantages of each coating in mechanical durability and deicing under ultra-low temperature conditions.The results show that the primer-finish composite superhydrophobic coating has excellent mechanical durability,and the ice adhesion strength is less than 30 kPa after 40 abrasion under a 250 g load of the abrasion meter and after 100 freezing/melting cycles;the hydrophobic nanoparticle-lubricating grease composite coating has excellent deicing performance at ultra-low temperature-150℃,and its initial ice adhesion strength is only11.5 kPa.The research results of this thesis will provide useful theoretical and practical guidance for the application of hydrophobic/superhydrophobic coatings in the field of anti-icing.
