Problems solved by technology

[0004] At present, most of the icing surfaces are deiced by pure electric heating. This method consumes a lot of energy and cannot meet the deicing requirements when the ice accumulation intensity is too high.
[0005] In addition, the low efficiency of traditional electrothermal deicing devices is also a major shortcoming of its practical application

Abstract

The invention discloses an electrical heating anti-icing assembly with a superhydrophobic property and a preparation method of the electrical heating anti-icing assembly. The anti-icing assembly comprises an insulation heat insulating layer, an electrically heating layer, an insulation heat conduction layer, a heat conduction metal layer, a superhydrophobic coating and waterproof adhesive tape, wherein the insulation heat insulating layer, the electrically heating layer, the insulation heat conduction layer, and the heat conduction metal layer are successively spliced from bottom to top, the superhydrophobic is coated on the surface of the heat conduction metal layer, and the waterproof adhesive tape is sealed around the assembly. The electrical heating anti-icing assembly with the superhydrophobic property has the beneficial effects that the anti-icing assembly has the superhydrophobic property and can remarkably reduce the adhesive strength of a surface ice layer, thus formation of the surface ice layer and removing difficulty of the ice layer can be reduced in a certain level, the ice layer covered on the surface can be removed quickly and completely, heating time is shortened,the removing efficiency of the ice layer is greatly improved, waste of energy is reduced, and great application prospects are provided for equipment such as an airplane in the ice removing field.

Description

technical field [0001] The invention relates to an anti-icing component and a preparation method thereof, in particular to an electrically heated anti-icing component with superhydrophobic properties and a preparation method thereof, belonging to the technical field of anti-icing. Background technique [0002] In the fields of aviation, transportation, and wind power generation, icing on the surface of equipment and equipment will reduce its performance and work efficiency, and even cause safety hazards in severe cases. When the aircraft is flying at high altitude, the supercooled water droplets in the clouds are prone to freezing and accumulating ice after contacting the fuselage. The icing on the wings and engines seriously affects the controllability of the aircraft. In the process of wind power generation, the thick ice layer will cause the blades of wind turbines to be overloaded or even deformed, shortening the service life. In recent years, in view of the huge loss o...
