Problems solved by technology

[0006] Although the existing camouflage tarpaulins can cover and camouflage certain spectral bands, they have narrow camouflage spectral bands and cannot resist the reconnaissance of optical, infrared, and radar spectrums at the same time. Advanced reconnaissance technology for effective countermeasures, especially in bad weather and climate conditions, the performance of camouflage deteriorates significantly

Embodiment 1

[0035] Such as figure 1 As shown, the optical, infrared, and radar multi-spectrum camouflage tarpaulins involved in the present invention sequentially include a camouflage layer 1, a radar wave forward scattering layer 2, a radar wave absorbing layer 3, a fabric base layer 4, and a reflective layer 5 from outside to inside. Five functional layers.

[0036] The base layer of the fabric is made of 1000D, 20×20 polyester filament woven fabric, and the upper and lower surfaces of the woven fabric are uniformly coated with a PVC paste resin coating with a thickness of 0.15mm by a scraping process, and the PVC paste resin is coated. The physical and chemical properties of the materials are shown in Table 1.

[0037] Table 1: Physical and chemical indicators of materials coated with PVC paste resin

[0038]

[0039] For the lower surface of the fabric base layer, use acetone and ethanol mixed solvent (1:1 volume ratio) to carry out chemical degreasing; after natural drying, use ...

Embodiment 2

[0047] In this embodiment, using the same manufacturing process and materials, after the camouflage layer, the radar wave forward scattering layer, the radar wave absorbing layer, and the fabric base layer after electroless copper plating are all prepared, the above-mentioned functional layers are sequentially assembled by sewing technology. , and stitched together in a pattern of warp and weft interweaving with a stitch spacing of 1 meter to prepare such figure 1 The optical, infrared, radar multi-spectral camouflage tarpaulin with multi-layer composite structure is shown.

Embodiment 3

[0049] In this embodiment, the metal reflective layer is prepared by vacuum aluminum plating instead of the chemical copper plating process. The vacuum aluminum plating equipment used is the SBD1200-10III vacuum aluminum plating machine developed by Wuxi Jinchi Automation Equipment Co., Ltd., and the thickness of the aluminum coating is 50um. The remaining steps are completely in accordance with the operation in Example 1. Finally, the 5550 type two-component polyurethane adhesive produced by Dongfang Chemical Co., Ltd. is selected to bond the above functional layers into one body in order to prepare the following: figure 1 The optical, infrared, radar multi-spectral camouflage tarpaulin with multi-layer composite structure is shown.

Abstract

The invention discloses an optical, infrared and radar multispectral camouflage canopy. The multispectral camouflage canopy has a multi-layer compound structure, and is sequentially provided with a camouflage layer, a radar wave forward scattering layer, a radar wave absorption layer, a fabric base layer and a reflection layer from outside to inside, wherein the camouflage layer is optical and infrared two-fold nested camouflage, and can achieve optical and infrared wave band camouflage synchronously; the radar wave forward scattering layer is a dielectric fiber oriented fabric, and can guide a radar wave into the radar absorption layer which is a sponge body filled with ferrite powder and can efficiently consume and scatter radar wave energy; the fabric base layer provides physical support for the camouflage canopy; the reflection layer covers the inner surface of the fabric base layer so as to reflect an external radar wave externally so as to form a secondary absorption effect, and also can reflect internal heat radiation so as to prevent external leakage of an internal heat characteristic. The multispectral camouflage canopy is scientific in design, is advanced in index and is suitable for popularization in the industry, the raw materials are easily available, and the manufacture process is mature.

Description

technical field [0001] The invention relates to a camouflage tarpaulin, in particular to a camouflage tarpaulin with optical, infrared and radar multi-spectrum camouflage functions. Background technique [0002] The victory of intelligence and information is the foundation of modern warfare, and military camouflage technology is developed to counter enemy military reconnaissance. The early military reconnaissance methods mainly relied on the naked eye observation of soldiers. Due to the physiological limitations of the human body, the effective range of naked eye reconnaissance is short, and the target recognition ability is low. Covering the surface of one's own target with different types of coverings can confuse the enemy. , to hide one's own purpose. [0003] Since the Industrial Revolution, high-power telescopes and other new optical equipment have been widely used in the battlefield, which has effectively promoted the development of military reconnaissance technology ...
