Problems solved by technology

However, the color varieties of infrared stealth coatings are still less at present, and no color series has been formed; in addition, when infrared stealth coatings are coated, the thickness is large, resulting in a large weight, which is inconvenient to carry and apply; coatings made of infrared stealth coatings, Its physical and mechanical properties and adhesion are low, and it is difficult to accept ultraviolet radiation and atmospheric corrosion for a long time; and the infrared emissivity of visible light and infrared compatible camouflage materials using infrared stealth coatings is relatively high, above 0.6, and it is difficult to meet the requirements of military materials

Abstract

The invention discloses a visible light and infrared light compatible camouflage material which is of a layered structure and sequentially comprises a substrate, a low infrared emissivity layer and an oxide film layer from bottom to top; and the oxide film layer is a Cr2O3 film. A preparation method comprises the following steps: (1) preparing the low infrared emissivity layer on the substrate through a radio frequency magnetron sputtering method; and (2) preparing the Cr2O3 film on the surface of the low infrared emissivity layer through the radio frequency magnetron sputtering method, and finishing preparation of the visible light and infrared light compatible camouflage material. According to the visible light and infrared light compatible camouflage material, the color of the oxide film layer can be regulated and controlled and can be green and also other multiple colors, and the visible light and infrared light compatible camouflage material can be suitable for camouflage requirements under different conditions.

Description

technical field [0001] The invention belongs to the field of stealth materials, in particular to a visible light and infrared compatible camouflage material and a preparation method thereof. Background technique [0002] In modern warfare, with the continuous development of detectors, single-band camouflage materials are difficult to meet the needs of modern warfare. It is an inevitable trend in the development of camouflage technology to achieve multi-band compatible camouflage such as visible light and infrared. [0003] Visible light and infrared camouflage materials refer to camouflage materials that have both visible light and infrared camouflage properties. On the one hand, it must have different colors, and can use its own color characteristics to reduce the brightness, color and motion contrast between the target and the background, so as to control the visual signal of the target, so as to reduce the detection of the target by the visible light detection system. pr...
