Embodiment 4
[0030] Example 4 is used to provide a screening comparison of the mesh diameter and the immersion grammage of the wave-absorbing coating.
Embodiment 1
[0032] The ratio of each component in the wave-absorbing coating of the present invention is: distilled water 20%, adhesive 65%, absorbent 8.7%, dispersant 3.2%, defoamer 0.1%, thickener 1.5%, crosslinking agent 1.5%.
[0033] The preparation process of the wave-absorbing coating is as follows: Weigh distilled water, adhesive, absorbent, dispersant and defoamer, rotate at 900r / min, disperse for 30min; then add thickener, crosslinking agent, rotate at 700r / min , dispersed for 20 minutes.
[0034] Surface layer preparation: base fabric is coated with flame-retardant coating on both sides, after drying, one side is coated with wave-absorbing coating and dried, and then both sides are coated with camouflage coating, after drying, it is made into camouflage monochrome cloth, which is made by mosaic and cut flower process into the surface layer;
[0035] Interlayer preparation: Use mesh cloth with a mesh diameter of 0.4mm to impregnate the wave-absorbing coating for the interlayer...
Embodiment 2
[0042] The ratio of each component in the wave-absorbing coating in the present invention is: distilled water 18%, adhesive 66%, absorbent 10%, dispersant 3.5%, defoamer 0.2%, thickener 0.8%, crosslinking agent 1.5%.
[0043] The preparation process of the wave-absorbing coating is as follows: Weigh distilled water, adhesive, absorbent, dispersant and defoamer, rotate at 800r / min, disperse for 25min; then add thickener, crosslinking agent, rotate at 600r / min , dispersed for 20min
[0044] Surface layer preparation: base fabric is coated with flame-retardant coating on both sides, after drying, one side is coated with wave-absorbing coating and dried, and then both sides are coated with camouflage coating, after drying, it is made into camouflage monochrome cloth, which is made by mosaic and cut flower process into the surface layer;
[0045] Interlayer preparation: Use a mesh cloth with a mesh diameter of 0.6mm to impregnate the wave-absorbing coating. After drying, the impr...

Abstract
The invention relates to a sandwich structure camouflage net and a preparation method thereof. The sandwich structure camouflage net is prepared by edge covering and quilting of a surface layer, a sandwich layer and a bottom layer, wherein the surface layer is prepared by coating two surfaces of base cloth with flame-retardant paint, drying, coating one surface with wave-absorbing paint, drying, coating two surfaces with camouflage paint, drying to prepare camouflage single-color cloth, and preparing the camouflage single-color cloth into the surface layer by a picture splicing and pattern cutting process; the sandwich layer is prepared by dipping mesh cloth with the wave-absorbing paint, and drying; the bottom layer is prepared by coating two surfaces of the base cloth with the flame-retardant paint, drying, coating one surface with the wave-absorbing paint, drying, coating two surfaces with infrared paint, and cutting holes. The sandwich structure camouflage net is a multi-spectrum camouflage net with excellent low-frequency radar camouflage and stealth performance, and has anti-hooking and flame-retardant performance.
Description
technical field [0001] The invention belongs to the technical field of camouflage and stealth, and specifically relates to a method for preparing an interlayer material used in a camouflage net with a sandwich structure and a camouflage net structure. Background technique [0002] Camouflage and stealth is an important part of combat support and an effective means to counter military reconnaissance and attacks. Under the conditions of high-tech warfare, the role and status of camouflage become more prominent. Camouflage net is one of the most basic, most effective and cost-effective stealth camouflage equipment. Its use can reduce or even eliminate various exposure features of the target, conceal the existence of the target, and is the camouflage stealth equipment with the best camouflage effect. [0003] The radar wave stealth mechanism of the camouflage net can be described as: part of the electromagnetic wave emitted by the radar antenna is scattered by the outer struct...
