偽裝是指通過電磁、光學、熱、聲學等技術手段，改變目標原有的特征信息，隱真顯假，降低敵人的偵察效果，使敵人對自己的位置、企圖和行動產(chǎn)生錯覺，導致自己指揮失誤，從而保存自己，打擊敵人。
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.
隨著科學技術的飛速發(fā)展，光電探測技術、探測手段等反偽裝技術已經(jīng)發(fā)展到相當高的水平。傳統(tǒng)的可見隱身是通過縮小目標的可見形狀、涂覆偽裝迷彩、覆蓋偽裝網(wǎng)等手段，盡可能地降低目標與背景的視覺對比度特性，如亮度、色度等。色牢度差，在野外長期使用后容易褪色，容易被光學儀器和熱成像系統(tǒng)檢測出來。
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.
一種復合偽裝網(wǎng)，具有偽裝網(wǎng)體，偽裝網(wǎng)體自下而上主要由微孔膜層、金屬涂層、粘合劑層、織物層和表面涂層組成。偽裝網(wǎng)體的上表面設有偽裝層，偽裝網(wǎng)體的下表面設有底網(wǎng)，偽裝網(wǎng)體的上下表面設有連接底網(wǎng)和偽裝層的固定繩。進一步地，微孔膜層是具有許多三維不規(guī)則微孔的結(jié)構膜，由聚乙烯、聚丙烯、聚氨酯或長鏈聚四氟乙烯制成。此外，所述微孔薄膜層和金屬涂層的厚度為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，所述微孔薄膜層的上表面、次表面和微孔壁上通過濺射、化學氣相沉積或化學鍍涂覆有鋁、銀、金、銅、鋅、鈷、鎳、鉑或它們的合金的金屬涂層，使得所述微孔薄膜層具有1-6個光密度單位。此外，織物層由對熱紅外透明而對可見光不透明的織物、合成材料如無紡或紡織聚酰胺、聚酯和聚烯烴、或棉、毛、絲及其混合物制成。進一步地，表面涂層由20%-30%的丙烯酸聚合物粘合劑、35%-40%的顏料、35%-40%的阻燃劑和0.08%-0.15%的乳化劑組成，并溶解在由水和氨水組成的混合溶劑中。
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.
