Problems solved by technology

Due to the flexibility of natural vegetation, high and low temperature resistance, weather resistance, etc. are weak, and the machinability is not strong, the focus of camouflage and stealth materials is mainly on bionic organic materials. A microwave absorbing material disclosed in the prior art [CN206330484U] Composite bionic grass, and [CN106751276A] provides stealth materials made of bionic organic materials, which are used to camouflage natural vegetation to hinder the resolution effect of hyperspectral detection equipment, but still fail to achieve the natural camouflage effect of natural vegetation

Embodiment 1

[0018] Embodiment 1: A kind of plant stealth material, by loofah unit and electromagnetic shielding cloth, structure such as figure 1 , wherein the loofah unit 2 and the loofah unit 2' are distributed and fixed on the electromagnetic shielding cloth 1 in parallel in the figure, the loofah unit part 3 is impregnated with the wave-absorbing liquid, and the bottom surface is connected with the electromagnetic shielding cloth, and the loofah unit part 4 is not impregnated with the absorbing liquid Wave liquid, exposed to the air, 5 is the fan-shaped cavity of the loofah unit.

[0019] Such as Figure 4 Shown, this embodiment preparation method is as follows:

[0020] Screen, select a loofah with a suitable diameter, cut off the two ends, and keep the more regular cylinder in the middle.

[0021] Cut, according to the number of vascular bundles of the loofah, cut it into strips of loofah, cut 3 vascular bundles (3 fan-shaped cavities) into 3 strips, cut 4 vascular bundles (4 fan-...

Embodiment 2

[0028] A kind of plant stealth material, which is composed of loofah unit and electromagnetic shielding cloth, the structure is as follows image 3 As shown in the figure, the loofah unit 7 and the loofah unit 7' are distributed and fixed on the electromagnetic shielding cloth 6 in parallel. The loofah units are partially soaked in the wave-absorbing liquid, the bottom surface is connected with the electromagnetic shielding cloth, and the top is exposed to the air.

[0029] The preparation method of this embodiment is as follows:

[0030] Screen, select a loofah with a suitable diameter, cut off the two ends, and keep the more regular cylinder in the middle.

[0031] Cut, according to the number of vascular bundles of the loofah, cut it into strips of loofah, cut 3 vascular bundles (3 fan-shaped cavities) into 3 strips, cut 4 vascular bundles (4 fan-shaped cavities) into 4 strips.

[0032] Soak in the absorbing liquid, inject the absorbing liquid into the stainless steel squ...

Abstract

The invention relates to a plant stealth material and a preparation method thereof, and concretely relates to a loofah sponge stealth material and a preparation method thereof. The plant stealth material is composed of loofah sponge units and an electromagnetic shielding cloth, the loofah sponge units are partially impregnated in a wave absorbing liquid, and the loofah sponge units are distributedand fixed on the upper surface of the electromagnetic shielding cloth. The preparation method comprises the steps of screening, cutting, wave absorbing liquid impregnation, drying, slitting and sewing. The method has a simple process, and is convenient to operate, and the product has a microwave broadband stealth performance, a visible light/near infrared camouflage and thermal infrared stealth function and an electromagnetic shielding performance, and further has the advantages of small density, flexibility, high strength, resistance to high temperature and low temperature, greenness, environmental friendliness and long service life.

Description

technical field [0001] The invention relates to a plant stealth material and a manufacturing method thereof, in particular to a loofah stealth material and a manufacturing method thereof. Background technique [0002] At present, the types of camouflage / stealth materials commonly used at home and abroad mainly include: wave-absorbing coatings, camouflage coatings, camouflage nets, cover cloths, composite structural materials, etc. These types of materials are relatively mature in technology and widely used. , each has its own characteristics and different applications, but they are all non-plant materials. In recent years, metamaterials and superstructure materials have become research hotspots in the field of camouflage and stealth technology, but the technical problems of multi-spectrum camouflage and microwave broadband stealth have not yet been solved. Hyperspectral detection equipment can distinguish whether the ground background is a polymer material covering (cover, ...
