AB  - With the widespread development of pumped storage power station planning and construction, the winter operation of existing high cold area face rockfill dams is significantly affected by ice damage, leading to problems such as easy detachment after long-term immersion, delamination due to frost heaving, and damage from ice pushing and ice scraping of traditional surface protective materials for panels. To meet the performance requirements of surface protective materials for panels in cold regions, a fluorine-modified polyurethane surface anti-icing material has been prepared using the fluorine-terminated agent 1H, 1H, 2H, 2H-perfluorooctanol. The ice adhesion strength, mechanical properties, and water resistance of the materials were experimentally demonstrated. After a winter on-site engineering verification of the 1#~2# panels on the left bank of the upper reservoir dam at a pumped storage power station in a severe cold region, the material did not exhibit long-term immersion or delamination and showed good anti-seepage and anti-icing performance. These results represent a breakthrough in surface waterproofing and anti-icing technology for concrete face rockfill dams in high cold regions.
