Abstract

The invention discloses an optical camouflage compatible laser protection material and a preparation method and application thereof. The components and their mass parts in the novel laser protection material are as follows: 0.5-5 mass parts of laser absorbing material, 40-50 mass parts of organic solvent, 40-60 parts by mass of transparent resin, 5-30 parts by mass of hueing pigment, and 0.3-0.5 part by mass of auxiliary agent. The protection material provided by the invention can be compatible with optical camouflage and laser stealth protection, the wavelength range of laser protection is wide, and can meet the protection requirements of laser detection of various wavelengths; the preparation method of the protection material involved in the invention has a simple process, can be mass-produced, and It can be indirectly used in the processing of camouflage fibers, and the prepared products can be widely used in anti-laser reconnaissance, anti-laser eavesdropping and military camouflage.

Description

technical field [0001] The invention relates to the technical field of camouflage protection, in particular to an optical camouflage compatible laser protection material and a preparation method and application thereof. Background technique [0002] With the rapid development of military technology, laser-guided weapons have gradually become the protagonists of modern information warfare, and the existing camouflage stealth protection technology has not considered the laser protection performance, which makes military equipment and combat personnel severely threatened by laser-guided weapons and equipment. How to improve laser protection technology is also the focus of future military protection technology development. It should be pointed out that laser protection is difficult to be compatible with optical camouflage due to the need to greatly reduce the reflection of near-infrared light. This difficulty also greatly limits the application of laser protection materials. ...
