Abstract

The invention relates to an antistatic air bag material for a stratospheric airship and a preparation method thereof. The air bag material is prepared by arranging an antistatic layer at one side of a supporting layer and successively arranging a bonding layer, a gas blocking layer and an antistatic layer at the other side of the supporting layer, wherein the antistatic layer arranged on the surface of the supporting layer is a film containing a polythiophene-based conductive polymer and having a thickness of 0.4 to 2.3 [mu]m, the gas blocking layer is a polymer film, and the antistatic layer arranged on the surface of the gas blocking layer is a film containing a polythiophene-based conductive polymer and having a thickness of 0.05 to 0.8 [mu]m. According to the invention, the air bag material has substantially improved antistatic performance without influence on surface density and physical and mechanical properties of the air bag material; the antistatic performance of the material in the processes of assembly and usage is improved; static damage in the processes of assembly and usage of the air bag material is effectively avoided; and safety of the stratospheric airship in the process of usage is guaranteed.

Description

technical field [0001] The invention relates to an aerospace material, in particular to an air bag material for a stratospheric airship. Background technique [0002] With the advancement of science and technology, the stratospheric airship is a new type of near-space multifunctional flight platform that has been continuously developed. It has application advantages in many fields such as high-altitude reconnaissance, earth observation, communication relay, and space detection. research hotspot. The airbag of the airship plays the role of adjusting the balance of the flying height and the hull. It should have extremely high resistance to buoyant gas penetration, flexibility and bending resistance, good wear resistance, light weight, and moderate strength. A single material cannot fulfill multiple performance indicators of the airbag material with high quality, especially the antistatic performance of the airbag material, which directly affects the safety and service life of...
