Invisible sunshading polymeric membrane

Abstract

The invention relates to an invisible sunshading polymeric membrane which comprises a base layer (1) and a surface layer (2). The invisible sunshading polymeric membrane is characterized in that a heat insulation layer (3) and a radar absorbing layer (4) are sequentially arranged between the base layer (1) and the surface layer (2), the heat insulation layer (3) is arranged on the base layer (1) and made of polyurethane foamed plastics, the radar absorbing layer (4) is arranged between the surface layer and the heat insulation layer (3) and is oxygen iron, the base layer (1) is made of fabric comprising a surface layer, a lining layer and an intermediate layer connected between the surface layer and the lining layer, and the surface layer and the lining layer are fabricated into a whole through warps and wefts. The invisible sunshading polymeric membrane can effectively evade radar and infrared detectors so as to be invisible. Besides, the invisible sunshading polymeric membrane has the sunshading effect.

Description

(1) Technical field [0001] The invention relates to a polymer film. (2) Background technology [0002] In modern warfare, the competition is not only about numbers, bravery, and tactics, but also a competition of weapon technology. With the emergence of radar and infrared detectors, the invisibility of military weapons is not only invisible in color, but also requires the ability to Avoiding radar, infrared and other detectors, ordinary military vehicles do not have such a function, how to make ordinary military vehicles equipped with an invisible coat, the first thing that comes to mind is to put a layer of film on the military vehicle, and the general film has no invisible function, which cannot satisfy Require. And it does not have shading and sound insulation effects. (3) Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide an invisible light-shielding polymer film. [0004] The object of the prese...
