Problems solved by technology

However, limited to the conditions at that time, the stealth wavelength range of camouflage camouflage fabrics was limited to the visible light to near-infrared 1.5 μm band, and no in-depth analysis of the reflection spectrum characteristic curve and dye structure of dyed fabrics was carried out.

Embodiment Construction

[0016] A nano-stealth material, which is composed of aluminum-doped zinc oxide powder and phase-change microcapsules, the weight ratio of aluminum-doped zinc oxide powder and phase-change microcapsules is 1-3:1-3 (example: 1:1, 1 :3, 3:1), prepared by the following steps:

[0017] (1) Preparation of aluminum-doped zinc oxide powder:

[0018] Zinc acetate and aluminum isopropoxide are used as raw materials (ZnO sol is prepared by conventional zinc acetate and alcohol amine solution, Al is prepared by conventional aluminum isopropoxide and peptizer) 2 o 3 sol), ZnO sol and Al 2 o 3 Sol (or prepared by other conventional processes), and then mix the two to obtain a composite sol, age to gel the sol, and then calcinate at a high temperature at 900~1200°C (for example, 900°C, 1100°C, 1200°C). Obtain aluminum-doped zinc oxide powder;

[0019] (2) Preparation of phase change microcapsules:

[0020] Use solid paraffin and liquid paraffin to compound, and then prepare phase chang...

Abstract

The invention discloses a nano-stealth material and application thereof in an infrared camouflage fabric. The nano-stealth material comprises aluminum-doped zinc oxide powder and phase change micro-capsules, wherein the weight ratio of the aluminum-doped zinc oxide powder to the phase change micro-capsules is (1-3): (1-3). The nano-stealth material with excellent performances adopts an aluminum-doped zinc oxide low-emissivity material and the phase change micro-capsules with phase change temperature of 30-40 DEG C; and coating finishing is adopted for treating aluminum-doped zinc oxide and the phase change micro-capsules onto a textile so as to obtain a functional fabric with a good camouflage effect for a whole infrared wave band.

Description

technical field [0001] The invention relates to a nano stealth material and its application in infrared camouflage fabrics. Background technique [0002] Infrared reconnaissance technology is the main method of reconnaissance in modern warfare. The infrared window of the atmosphere has 3 bands: 1-2.5μm, 3-5μm, 8-14μm. Near-infrared night vision devices, low-light night vision devices, photographic reconnaissance and other near-infrared surveillance equipment generally have a working band of 0.76-1.5 μm, which mainly uses the brightness difference between the target and the background to identify. The 8-14μm thermal infrared reconnaissance uses the difference in infrared radiation intensity (temperature difference) between the target and the background to identify the target. Infrared camouflage technology is an important means to avoid military targets and weapons and equipment from being discovered by the enemy, and to improve the survivability of weapons and equipment an...
