TH2118A - Heat camouflage sheet - Google Patents

Abstract

The fabrication involves a heat shield consisting of a strength layer (4), for example a woven material with a layer that It is a polyethylene film (1) with metal adheres to one side. It was stacked using fused glue (3) to stack the floor. The surface is embossed to make the skin not oily. Because of transparent polyethylene Clear for infrared light, has a low individual reflection. By applying a metal layer (2), a reflection mask is obtained. Therefore, the outer layer (1) in the thermal equilibrium is rarely affected. For example by hot things Covered with material and the outer layer has a low radiating capability of about 0.6 to 0.8 layers with the thickness and color by adding layers (5) to form a vignette when photographed with infrared light at a wavelength of 3 - 5 μm. And 8 - 14 μm

Claims (8)

1.Heat camouflage sheet Including the cover material with a strength layer (4) the outer layer is plastic (1), which in 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 a high transmission condition 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 is the plastic layer of 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 having provided at least patches of the 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)
