Problems solved by technology

[0003] At present, traditional means such as gas heat / electric heat deicing are still the main means of aircraft anti-icing, but these means generally consume a lot of energy and are highly passive
In addition, the airbag deicing method also seriously affects the aerodynamic shape of the aircraft.
Therefore, the above-mentioned deicing methods are relatively limited, and cannot be effectively prevented. The anti-icing and deicing effect is single, and only has anti-icing or deicing functions, etc., and there are many problems.

Abstract

The invention provides an anti-icing film and a preparation method thereof. The method comprises the steps that the surface of a heating film is cleaned through absolute ethyl alcohol till the surfaceis clean, and the surface is naturally aired; the surface of the heating film is coated with a super-hydrophobic coating or a lower-surface-energy anti-ice coating; and curing is carried out, and theanti-icing film is obtained. The anti-icing film can meet the fields with the anti-ice requirement in the aerospace field, the anti-icing film can be powered on for heating and ice removal even though the anti-icing film is iced under the extremely severe or accidental conditions, and the anti-ice and deicing functions are both achieved.

Description

technical field [0001] The present invention relates to an anti-icing film, in particular to an anti-icing film and a preparation method thereof. Background technique [0002] Icing is a common natural disaster that seriously threatens the safety of aerospace, and even causes serious economic losses. The icing on the surface of the aircraft, especially the icing on the wing surface will cause serious harm to the flight safety of the aircraft. Icing may lead to a serious decline in the aerodynamic performance of the aircraft, and has been identified by the aviation industry as one of the six meteorological factors affecting aircraft flight. Therefore, the anti-icing / de-icing technology of the aircraft surface has always been concerned. The development of high-efficiency, energy-saving, and active anti-icing new materials and new technologies has become the main direction of aircraft anti-icing / de-icing technology development. [0003] At present, traditional means such as ...
