Problems solved by technology

[0004] At present, there are not many reports on multi-band camouflage materials. From the perspective of existing technology, camouflage materials with a single function in each band have reached the application stage, but they can be truly compatible with Camouflage materials in multiple bands such as visible light, near infrared, thermal infrared, centimeter wave, and millimeter wave are still rare
The existing camouflage compatible materials can only be compatible to two or three bands at most, but the compatibility effect is not ideal, and has not yet entered the practical stage. For those compatible with three bands, the camouflage effect can not meet the use requirements
Broadband camouflage nets have been developed and equipped at home and abroad, but the production process of these camouflage nets is complicated, mass production requires professional factories, and the absolute cost is still high
In addition, the multi-spectrum integrated camouflage performance of several types of camouflage coatings that are currently popular in the market still needs to be improved due to various reasons, and the market prices are also relatively high.
The existing camouflage layers are usually not very effective in comprehensive camouflage. They are either expensive, difficult to construct, and have a long construction period. Most of them are difficult to meet the high requirements for real-time camouflage and camouflage speed due to the rapidly changing battlefield environment.

preparation example Construction

[0046] The preparation method of the above-mentioned soft portable multispectrum composite camouflage material includes:

[0047] (1) On the side of the inner layer matrix 2 close to the target, evenly brush the acrylic waterproof paint added with fish beads and camouflage pigments, as the waterproof inner layer 1, with a thickness within 1-3mm;

[0048] (2) Place the glossy aluminum foil with high infrared reflection ability facing the barrier target, and glue it to the inner substrate 2 with fish bead glue;

[0049] (3) Mix ferrite powder, graphite fine powder, fish pearl glue, and camouflage pigment evenly, and paint on the aluminum foil as the transition layer 4, with a thickness within 1-3mm;

[0050] (4) Evenly paint the mixture of ferrite powder, graphite fine powder and epoxy adhesive on the transition layer 4, as the wave-absorbing layer 5, with a thickness between 2mm-5mm;

[0051] (5) When the wave-absorbing layer 5 is half dry, the outer layer substrate 6 is bonde...

Abstract

The invention discloses a multi-spectrum composite camouflage material and a preparation method thereof. The multi-spectrum composite camouflage material sequentially comprises a waterproof inner layer, an inner layer base body, an infrared reflective layer, a transition layer, a wave absorbing layer and an outer layer base body, and a waterproof outer layer, a heat insulation layer and a camouflage layer that are arranged on the outer side of the outer layer base body, or a vegetation layer disposed outside the outer layer base body, the infrared reflective layer and the heat insulation layerare used for infrared camouflage, the wave absorbing layer is used for radar camouflage, the camouflage layer and the vegetation layer are used for optical camouflage, and the infrared reflective layer is made of metal, the wave absorbing layer is made of a mixture comprising ferrite powder, graphite powder and an adhesive. The camouflage material provided by the invention can realize a visible light, infrared and radar multiband compatible camouflage effect, has good waterproofness and weather resistance, and is especially suitable for field operation.

Description

technical field [0001] The invention relates to the technical field of camouflage materials, in particular to a multi-spectrum composite camouflage material and a preparation method. Background technique [0002] In modern warfare, multi-band and multi-spectrum detection has become the new normal. Single-band camouflage materials can no longer meet the needs of modern warfare. Multi-band camouflage materials, especially radar, infrared and visible light compatible camouflage materials are an inevitable trend in the development of camouflage technology. At the same time, the rapidly changing battlefield environment also puts forward higher requirements for the real-time performance and speed of camouflage. [0003] Radar, infrared, and visible light camouflage materials refer to camouflage materials that have three camouflage properties of radar, infrared, and visible light at the same time. On the one hand, its surface material should have adjustable visible light reflectan...
