Embodiment 2

[0030] Such as figure 2 Shown, the preparation method of capsule material of the present invention comprises the following steps:

[0031] Step 1: Glue and compound the single-layer double-sided aluminum-coated TPU film through the laminating machine. After corona, uniformly coat nano-modified polyurethane glue, and corona-treated PBO high-strength fiber plain weave cloth Bonding, after compounding, winding, aging at 80°C to 100°C for one day to obtain a fully matured composite cloth;

[0032] Step 2: Scrape-coat the surface of the composite cloth obtained in Step 1 with polyurethane hot-melt adhesive added with nanomaterials, dry in a long drying tunnel, attach a release film, and roll and mature to obtain the capsule material.

[0033] In this embodiment, TPU double-sided aluminized film is used for compounding with PBO high-strength fiber plain weave cloth, and a nano-modified polyurethane two-component adhesive is used to improve the rubbing resistance of the capsule mat...

Abstract

The invention specifically relates to a nanometer modified capsule material for a high-altitude aerostat and a preparation method thereof, belonging to the field of aerospace materials. The capsule material comprises a blocking weather-proof film, a nanometer modified glue solution layer, a mechanical structure layer and a nanometer modified welding glue solution layer, wherein one surface of the mechanical structure layer is connected with the blocking weather-proof film through the nanometer modified glue solution layer while the other surface of the mechanical structure layer is connected with the nanometer modified welding glue solution layer; the mechanical structure layer is a PBO high-strength fiber plain weave fabric; and the nanometer modified welding glue solution layer is a polyurethane hot melt adhesive with a nano-material. The capsule material prepared in the invention has the beneficial effects of high strength, light weight, low helium permeability, good weatherability, strong performance in preventing a capsule from absorption of sun light energy in flight during daytime; and the preparation method is easy to operate and control.

Description

technical field [0001] The invention belongs to the field of aerospace materials, and in particular relates to a nano-modified high-altitude aerostat capsule material and a preparation method thereof. Background technique [0002] The high-altitude aerostat is a new type of near-space multifunctional flying platform with propulsion device, controllable flight, and relying on static lift to stay in the air. The working altitude is about 20Km above sea level. The flight characteristics of aerostats determine that they have broad application prospects in the fields of military reconnaissance, space early warning, communication relay and space detection, so they are widely favored by scientists from all over the world. However, the high-altitude working environment of aerostats is very harsh: low temperature, large temperature difference between day and night; low atmospheric density; strong ultraviolet radiation and ozone. Working in such an environment, firstly, the skin mate...
