Problems solved by technology

[0003] The traditional windshield anti-icing and anti-fog technology of the aircraft uses gas heat and anti-icing liquid, etc. The gas heat is heated by engine exhaust, the structure is complex and the efficiency is low, and the anti-icing liquid is only used for ground deicing, and the electric heating method adopted is simple Indium tin oxide single-layer film or resistive wire mesh has certain limitations in the uniformity of electric heating and sheet resistance, and at the same time, it does not significantly improve the auxiliary functions such as energy-saving performance of the windshield

Abstract

The invention discloses an electric heating film for airplane windshield glass ice and fog prevention and a preparation method thereof. The electric heating film for airplane windshield glass ice and fog prevention comprises a glass substrate, an inner structure layer, an electric heating function layer and an outer structure layer which are sequentially arranged from inside to outside. According to the electric heating film, electric heating performance is excellent, weather resistance and corrosion resistance are good, film layer visible light transmittance is high, the color is gentle, compact and uniform, light transmittance is uniform, electric heating ice and fog prevention performance can be improved, and the service life of the electric heating ice and fog prevention is prolonged.

Description

technical field [0001] The invention relates to the field of electric heating film manufacturing, in particular to an electric heating film used for anti-icing and anti-fogging of aircraft windshields and a preparation method thereof. Background technique [0002] During the flight, the aircraft will be affected by the meteorological environment and flight status. Some surfaces, such as the windshield, the leading edge of the wing, and the inlet port, will freeze and fog, which seriously threatens flight safety. In particular, the icing and fogging of the windshield will affect the pilot's vision and visual comfort to a large extent. Flying in the icing and fogging state for a long time will cause problems such as visual fatigue judgment errors. In order to improve this phenomenon, an electric heating film is coated on the inside of the windshield to effectively remove icing and fogging, and at the same time, it does not affect the visible light transmittance of the windshie...
