Description

Technical Field

[0001] The invention relates to the technical field of engineering camouflage applications, and in particular to an adaptive infrared camouflage imitation rock thin shell and a manufacturing method thereof. Background Art

[0002] The camouflage of targets such as tunnel entrances, buildings (structures) and vehicles located in mountainous areas is an important research direction in the field of protective engineering. Disguising the target as an ordinary stone near the mountain to form an effective deception is an effective camouflage method. The differences in material and surface properties between the existing imitation rock thin shells and real rock often lead to differences in infrared radiation temperature between the two, which in turn leads to exposure. Therefore, how to make the imitation rock thin shells and real rock have similar radiation temperature changes in different seasons and different time periods is an urgent problem that needs to be solved by infrared camouflage. At present, the target infrared radiation temperature is often controlled by controlling the thermal inertia of materials and the emissivity of the target surface, such as adding phase change materials, spraying low-emissivity coatings, etc. Due to the changes in solar radiation and temperature in different seasons at the same location, especially in the northern region, the temperature difference between summer and winter may reach about 50°C, which leads to greater restrictions on the selection of phase change points of phase change materials. Under the same heating conditions, since the thermal inertia of real mountain stone is large, while the thermal inertia of the imitation mountain stone thin shell is relatively small, the imitation mountain stone thin shell absorbs solar radiation quickly during the day, resulting in temperature rise, and the surface temperature of the imitation mountain stone thin shell is higher than that of the real mountain stone. From dusk to midnight, the opposite is true. The surface temperature of the imitation mountain stone thin shell drops rapidly, and the surface temperature of the imitation mountain stone thin shell is lower than that of the real mountain stone. After spraying low-emissivity coatings, although the radiation temperature difference between the real and fake mountain stones during the day can be better controlled, the radiation temperature difference between the real and fake mountain stones at night will increase; it still cannot meet the use requirements in the field of protective engineering.
