Embodiment 1

[0032]Infrared coatings with modulated infrared emissivity of 0.42, 0.63, 0.75, and 0.89 are ready for use, wherein each color corresponds to an emissivity, and the colors are silver, yellow, green, and black; a pattern of A4 size is generated by a computer, Among them, according to the area ratio of 30%, 20%, 20%, and 30%, four plaque patterns are generated, which are the first plaque pattern, the second plaque pattern, the third plaque pattern and the fourth plaque pattern , to print 4 copies of it as a template. Attach the A4 flexible film to the pre-treated A4 size polyethylene board, hollow out the first patch pattern, and paste the hollowed out edge, and spray the paint with an emissivity of 0.42 and a silver color on the flexible film. After spraying, peel off the flexible film, blow the air to dry the coating, and the dry film thickness of the sprayed coating is about 40 μm; after the coating is dry, repeat the steps of attaching the flexible film until the coating is ...

Embodiment 2

[0035] Infrared coatings with modulated infrared emissivity of 0.4, 0.55, 0.7, and 0.85 are ready for use, wherein each color corresponds to an emissivity, and the colors are red, yellow, green, and black; a pattern of A4 size is generated by a computer, Among them, according to the area ratio of 20%, 40%, 20%, and 20%, four plaque patterns are generated, which are the first plaque pattern, the second plaque pattern, the third plaque pattern and the fourth plaque pattern , to print 4 copies of it as a template. Attach the A4 cardboard to the pre-treated A4 size fiber film, hollow out the first patch pattern, and paste the hollowed out edge, spray the red paint with an emissivity of 0.4 on the cardboard, and spray After the coating is finished, remove the cardboard and wait for the coating to dry. The dry film thickness of the sprayed coating is about 40 μm; after the coating is dry, repeat the steps of attaching the cardboard until the coating is dry. Paste the hollowed-out e...

Embodiment 3

[0038] Modulate infrared paints with infrared emissivity of 0.4, 0.6, and 0.8 for use, wherein each color corresponds to an emissivity, and the colors are red, yellow, and green; use a computer to generate an A4-sized pattern, in which according to the area occupied The ratios are 30%, 40%, and 30% respectively to generate three patch patterns, which are the first patch pattern, the second patch pattern and the third patch pattern, and print three copies of it as a template. Attach the A4 flexible film to the pre-treated A4 size fiber film, hollow out the first patch pattern, and paste the hollowed out edge, spray the paint with an emissivity of 0.4 and the color is red on the flexible film, spray After the coating is finished, peel off the flexible film and wait for the coating to dry. The dry film thickness of the sprayed coating is about 40 μm; after the coating is dry, repeat the steps of attaching the flexible film until the coating is dry, hollow out the second patch patt...

Abstract

The invention provides a visible light and thermal infrared double camouflage material and a preparation method thereof. The preparation method comprises the following steps that a first coating to annth coating are provided, wherein the first coating has a first color and a first emissivity, the nth coating has an nth color and an nth emissivity, and the n is a positive integer larger than or equal to 2; a camouflage pattern with a first patch pattern to an nth patch pattern is generated; a first coating is coated, and a first drawing is uncovered after the coating is finished; the steps from attaching the drawing to a substrate to removing the drawing are repeated until the nth coating is coated on the nth drawing, the nth drawing is uncovered after the coating is finished, and after the coating of the nth patch pattern is dried, the visible light and thermal infrared double camouflage material is namely obtained. The double camouflage material is capable of remarkably reducing thethermal imaging brightness of a target and effectively segmenting the appearance characteristic of the target.

Description

technical field [0001] The invention relates to a stealth material, in particular to a visible light and thermal infrared double camouflage material and a preparation method thereof. Background technique [0002] With the continuous development of modern military detection technology, especially the successive use of infrared sensing systems and infrared imagers, infrared stealth technology has become more and more difficult. Infrared stealth materials are mainly aimed at the detection of infrared thermal imaging cameras. Infrared thermal imaging cameras use the thermal radiation imaging of targets. They have good concealment, long night vision distance, strong anti-interference ability, and are suitable for various complex and harsh battlefield environments. With the wide application of infrared thermal imaging cameras in recent years, the research on infrared stealth materials has become very important. [0003] At present, it generally focuses on visible light and near-i...
