Abstract

The invention discloses a material with both optical camouflage and laser protection functions and a preparation method and application thereof. The material comprises the following components in parts by mass: 0.5-5 parts of a laser absorption material, 40-50 parts of an organic solvent, 40-60 parts of transparent resin, 5-30 parts of a toning pigment and 0.3-0.5 part of an auxiliary agent. The material provided by the invention has the compatible optical camouflage and laser stealth protection functions, is wide in the wavelength range of laser protection, and can meet the protection requirements of detection of lasers with various wavelengths. The preparation method of the material is simple in process, can achieve mass production, and can be indirectly used for processing of camouflage fibers and the like; and the prepared material can be widely applied to laser reconnaissance prevention, laser eavesdropping prevention, military camouflage and the like.

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 its preparation method and application. Background technique [0002] With the rapid development of military technology, laser-guided weapons have gradually become the protagonists of modern information warfare. However, the existing camouflage and stealth protection technology has not considered the laser protection performance, so that military equipment and combat personnel are seriously 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 because laser protection needs to greatly reduce the reflection of near-infrared light, it is difficult to be compatible with optical camouflage, and this difficulty also greatly limits the application of laser protection mate...
