TH3640B - Heat camouflage sheet - Google Patents

Abstract

The invention involves a thermal camouflage sheet consisting of a reinforcing layer (4), for example, a woven material, which has a It is a film of polyethylene (1) with a metal adhesion on one side. They were stacked using melt adhesive (3) to stack the floor. The skin is embossed to make it non-oily. because polyethylene is transparent Clear for infrared light with low unique reflection. By using a metal layer (2), the reflection is masked. Therefore, the outer layer (1) that is in thermal equilibrium is almost unaffected. such as by hot things Covered with material and the outer layer has a low radiance, about 0.6 - 0.8 layers with thickness and color, adding a layer (5) will get a patchwork image when photographed with infrared light in the wavelength range of 3 - 5 μm. and 8 - 14 micrometers

Claims (8)

1.Heat camouflage sheet Including the cover material with a strength layer (4) the outer layer is plastic (1), in which the length The visible waves have areas of different colors. For giving results Visual camouflage And between the strengthening layer and the outer layer there is a metallic reflective layer (2), characterized by The outer layer is a non-glossy finish to reduce spectral reflection.The metallic reflective layer is fractured into a patterned structure to avoid radar reflection. And plastic outer layer material (1) has high transmission conditions in the wavelength range 3 - 5 μm and 8-14 μm. 2. Heat camouflage sheet of claim 1, in which the plastic material of the outer layer (1) is polyethylene. Which is painted throughout with camouflage colors that are Low absorption in the infrared wavelength range. 3. The heat shield of claim 1 or 2, in which the strength layer (4) is woven with metallic threads, is the effect. Radar camouflage 4. The heat shield of claim 1, in which a metallic reflective layer (2) is placed on the outer layer. And the adhesion layer (3), which is the fusible adhesive, causes the strengthening layer (4) to adhere to the metallic side of the outer layer (1). 5. Heat shield of claim 4, which is on each side of the layer Provides strength (4) with a plastic outer layer (1, 1 \ ') attached by a bonding layer (3, 3 \') that is a fusible adhesive. 6. The heat camouflage sheet of claim 5, which plastic layer One side is polyethylene And on the other side is polyvinyl chloride. 7. The heat shield of any of the preceding claims that is characterized by providing at least patches of holes, an area equal to 5% of the total area. 8. The heat shield of any preceding claim looks that the outside of the plastic outer layer contains a piece of Plastic material placed away from each other (8 claims, 2 pages, 6 photos)
