▎ 摘　　要

NOVELTY - Anti-icing coating comprises self-healing polymer SH and hydrophobic filler in a ratio of 2:0.01-0.1. USE - Anti-icing coating used for self-healing under extreme environment. ADVANTAGE - The anti-icing coating has good antiicing performance, good ice cutting strength of 50 kPa, and reduces bare steel sheet to 90%. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing ice-resistant coating capable of self-healing under extreme environment, which involves: a. dissolving self-healing polymer SH in solvent to obtain material A; b. dispersing hydrophobic filler in solvent to obtain material B; c. uniformly mixing material B into material A to obtain material C; and d. coating material C on clean steel sheet and drying for 24-48 hours at room temperature to obtain self-healing anti-icing coating.
