The feasibility of preparing anti-deicing coatings based on low surface energy elastic polyurethane system was proposed.The anti-deicing effect of the prepared coating was tested in a large ice wind tunnel.Through the comparison with the domestic similar products,the anti-deicing effect is better.The feasibility of the research scheme was demonstrated from the aspects of coating ice adhesion characteristics and process parameter optimization,resin molecular structure design and synthesis process,resin elasticity regulation and optimization,coating surface state and surface energy regulation and optimization,icing wind tunnel verification,etc.
