Camouflage refers to the use of electromagnetic, optical, thermal, acoustic and other technical means to change the original feature information of the target, conceal the true and show the false, reduce the enemy's reconnaissance effect, make the enemy have an illusion of their position, intentions, and actions, leading to their own command errors, thereby preserving themselves and attacking the enemy.

随着科学技术的飞速发展，光电探测技术、探测手段等反伪装技术已经发展到相当高的水平。传统的可见隐身是通过缩小目标的可见形状、涂覆伪装迷彩、覆盖伪装网等手段，尽可能地降低目标与背景的视觉对比度特性，如亮度、色度等。色牢度差，在野外长期使用后容易褪色，容易被光学仪器和热成像系统检测出来。

With the rapid development of science and technology, anti camouflage technologies such as photoelectric detection technology and detection methods have developed to a considerable level. Traditional visible stealth is achieved by reducing the visible shape of the target, coating camouflage camouflage camouflage, and covering camouflage nets to minimize the visual contrast characteristics between the target and the background, such as brightness and chromaticity. Poor color fastness, easy to fade after long-term use in the field, and easy to be detected by Optical instrument and thermal imaging systems.

一种复合伪装网，具有伪装网体，伪装网体自下而上主要由微孔膜层、金属涂层、粘合剂层、织物层和表面涂层组成。伪装网体的上表面设有伪装层，伪装网体的下表面设有底网，伪装网体的上下表面设有连接底网和伪装层的固定绳。进一步地，微孔膜层是具有许多三维不规则微孔的结构膜，由聚乙烯、聚丙烯、聚氨酯或长链聚四氟乙烯制成。此外，所述微孔薄膜层和金属涂层的厚度为25um ~ 3.175mm。

A composite camouflage net with a camouflage net body, which is mainly composed of a microporous film layer, a metal coating, an adhesive layer, a fabric layer, and a surface coating from bottom to top. The upper surface of the camouflage net body is equipped with a camouflage layer, the lower surface of the camouflage net body is equipped with a bottom net, and the upper and lower surfaces of the camouflage net body are equipped with fixed ropes connecting the bottom net and the camouflage layer. Furthermore, the microporous membrane layer is a structural membrane with many three-dimensional irregular micropores, made of polyethylene, polypropylene, polyurethane, or long-chain polytetrafluoroethylene. In addition, the thickness of the microporous film layer and metal coating is between 25um and 3.175mm.

此外，所述微孔薄膜层的上表面、次表面和微孔壁上通过溅射、化学气相沉积或化学镀涂覆有铝、银、金、铜、锌、钴、镍、铂或它们的合金的金属涂层，使得所述微孔薄膜层具有1-6个光密度单位。此外，织物层由对热红外透明而对可见光不透明的织物、合成材料如无纺或纺织聚酰胺、聚酯和聚烯烃、或棉、毛、丝及其混合物制成。进一步地，表面涂层由20%-30%的丙烯酸聚合物粘合剂、35%-40%的颜料、35%-40%的阻燃剂和0.08%-0.15%的乳化剂组成，并溶解在由水和氨水组成的混合溶剂中。

In addition, the upper surface, secondary surface, and microporous wall of the microporous film layer are coated with metal coatings of aluminum, silver, gold, copper, zinc, cobalt, nickel, platinum, or their alloys through sputtering, chemical vapor deposition, or chemical plating, resulting in the microporous film layer having 1-6 optical density units. In addition, the fabric layer is made of fabrics that are transparent to thermal infrared but not transparent to visible light, synthetic materials such as non-woven or textile polyamides, polyester and polyolefins, or cotton, wool, silk, and their mixtures. Furthermore, the surface coating consists of 20% -30% acrylic polymer adhesive, 35% -40% pigment, 35% -40% flame retardant, and 0.08% -0.15% emulsifier, which are dissolved in a mixed solvent composed of water and ammonia.

具有抗光学和远红外能力，突破了传统的重复缺陷，色牢度高，长期使用不易褪色，满足了用户对光学伪装的更高要求，具有复合结构，通过控制目标热源与背景的温差，可以防止被光学仪器和热成像系统探测到；可以明显削弱热成像，降低可见光表面发射率。

It has the ability to resist optics and far-infrared, breaks through the traditional repeated defects, has high color fastness, is not easy to fade after long-term use, meets the higher requirements of users for optical camouflage, and has a composite structure. By controlling the temperature difference between the target heat source and the background, it can prevent being detected by Optical instrument and thermal imaging systems; It can significantly weaken thermal imaging and reduce Emissivity of visible light surface.
