Problems solved by technology

[0003] Traditional aircraft cockpit glass does not take into account the problem of UV damage and energy saving, but UV damage and energy saving are becoming more and more important for modern aircraft. At present, there is a lack of an energy-saving film with strong UV reflection performance for aircraft windshield with high UV reflection and its preparation method

Abstract

The invention discloses a high ultraviolet reflectance energy-saving film used for an airplane windscreen and a preparation method of the high ultraviolet reflectance energy-saving film. The high ultraviolet reflectance energy-saving film comprises a windscreen substrate, an internal silicon oxide layer, a high ultraviolet reflectance layer, an energy saving layer and an external silicon oxide layer, wherein the internal silicon oxide layer, the high ultraviolet reflectance layer, the energy saving layer and the external silicon oxide layer are arranged on the windscreen substrate from inside to outside sequentially. The windscreen substrate is an airplane windscreen substrate. The thin film is good in visible light transmittance, high in ultraviolet reflectivity and infrared reflectivity and simple in production process, is favorable for independent adjustment of the parameter performance of a film system, and is excellent in corrosion resistance and weather fastness.

Description

technical field [0001] The invention relates to the technical field of thin film manufacturing, in particular to an energy-saving thin film for high ultraviolet reflection of aircraft windshield glass and a preparation method. Background technique [0002] During the execution of missions, especially when the cruising state is above the clouds, the cockpit will be completely exposed to sunlight. At this time, if ultraviolet rays enter the cockpit directly through the windshield, it will damage the electronic equipment, pilots, electrical equipment, Clothes, etc. cause damage, reduce the service life of some components in the cabin, and cause harm to the pilot's glasses; at the same time, due to changes in flight status and environment during flight, the temperature difference between inside and outside changes drastically, and new requirements are put forward for the energy-saving performance of the windshield. , so as to save the energy consumption of the aircraft itself. A...
