A kind of laser stealth coating and preparation method thereof

Abstract

The invention provides laser camouflage coating. The laser camouflage coating comprises the following components in parts by weight: 40 to 60 parts of hydroxyl acrylic acid resin, 15 to 25 parts of laser absorbing pigment, 5 to 35 parts of color modulating pigment, 0.5 to 1 part of defoaming agent, 0.1 to 1 part of dispersing agent and the like. The preparation method comprises the following steps: dissolving the dispersing agent into a composite solvent, adding the color modulating pigment, the laser absorbing pigment and hydroxyl acrylic acid resin in an amount which is 1 / 2 of the weight ofthe hydroxyl acrylic acid resin, stirring uniformly, adding the defoaming agent and an anti-settling agent, mixing, grinding until the grain size is less than 10 um, adding the rest of components except for a curing agent, stirring uniformly, adding the curing agent, and stirring uniformly to prepare the laser camouflage coating. The laser camouflage coating has excellent physical and mechanical properties, can effectively absorb laser emitted by weapons with the laser wavebands of 810 nm, 850 nm, 905 nm, 908 nm and 1064 nm, has the absorbing coefficient being above 0.9, and has the optical camouflage function.

Description

technical field [0001] The invention belongs to the technical field of chemical materials, and in particular relates to a laser stealth coating and a preparation method thereof. Background technique [0002] Taking laser-guided weapons as the basic firepower and the main means of suppressing and killing are the obvious characteristics and main methods of future information warfare. Laser-guided weapons have high hitting accuracy, flexible target capture, strong ability to identify targets, and effective strikes on targets. Therefore, It poses a serious threat to the survival of military targets, and the improvement of the anti-laser guided weapon strike capability of important military targets is the focus of laser stealth. The commonly used military laser bands and their applications are shown in Table 1. [0003] Table 1 Commonly used military laser bands and applications [0004] [0005] As a convenient, economical and adaptable stealth technology, stealth paint has...

AI Technical Summary

Problems solved by technology

[0006] Existing research on laser stealth coatings is focused on absorbing the laser emitted by a single laser band or cannot be effectively compatible with optical camouflage performance
