The invention relates to a nanocomposite ice-coating-proof paint having properties of superhydrophobicity and low adhesive strength and a preparation method thereof. The nanocomposite ice-coating-proof paint is characterized by comprising such raw materials, by mass, as 3%-30% of a fluorine-containing polyacrylate copolymer, 40%-80% of a solvent, 0.05%-1.5% of a defoamer, 0.05%-1% of an anti-setting agent, 1%-15% of nanoparticles, and 1%-20% of a crosslinking-curing agent. Film thickness of an ice-coating-proof coating prepared by adopting the nanocomposite ice-coating-proof paint provided by the invention is 5-10 mum, the water contact angle is over 150 degrees and the maximum angle is up to 169 degrees, and the adhesive strength of ice on the coating surface is 1.43*10<-2>MPa. The coating has a significant effect on ice-coating proofing, and can be used for preventing ice-coating on such components as telegraph pole towers, heat pump air-conditioners, low-temperature refrigeration devices, aircraft components, and the like.
