Abstract

The invention provides a skin of a stratospheric aerostat and a preparation method thereof. The skin of the stratospheric aerostat comprises a weather resistant layer, a first air barrier and a force bearing layer in sequence, wherein the first air barrier comprises an aluminium coated PET (polyethylene terephthalate) layer, a first graphene-resin layer and / or a second graphene-resin layer; the aluminium coated PET layer is provided with a first surface and a second surface far from the first surface; the first graphene-resin layer is arranged on the first surface of the aluminium coated PET layer; the second graphene-resin layer is arranged on the second surface of the aluminium coated PET layer. In the skin of the stratospheric aerostat, the aluminium coated PET layer serves as a main structure layer of the first air barrier; the graphene-resin layers are introduced to the first surface and / or the second surface of the aluminium coated PET layer. In the practical application process, the aluminium coated PET layer can reflect off most sunlight, and the unreflected sunlight can be transmitted to the whole skin with the help of the first graphene-resin layer and / or the second graphene-resin layer with high heat conductivity, thus achieving the aim of rapid integral heat dissipation.

Description

technical field [0001] The invention relates to the technical field of aerostat manufacturing, in particular to a stratospheric aerostat skin and a preparation method thereof. Background technique [0002] The stratospheric aerostat is a new type of near-space multifunctional flying platform developed with the continuous development of science and technology. It is different from aircraft flying in the aviation layer, low-altitude aerostats, and satellites working in low orbits. It has a very wide range of military and civilian values, such as in missile defense, anti-terrorism, communications, remote sensing, and space observation. And atmospheric measurement and other aspects have great application value. [0003] As the main structure of the aerostat, the performance of the skin directly affects the application performance of the aerostat. The flight altitude of stratospheric aerostats is generally around 18-24km. The air in this area is thin and its density is about 1 / ...
