[0023] 1. Main production equipment
[0024] MDL200 type dry compound machine
[0025] 2. Composite material design and raw material selection
[0026] The flexible electromagnetic protection envelope composite material is composed of a barrier layer (1), a substrate layer (2), a heat-sealing layer (3) and an adhesive layer (4), wherein the inner and outer surfaces of the barrier layer (1) are bonded Each of the layers (4) is pasted with one base material layer (2), and the outer surfaces of the two base material layers (2) are respectively pasted with a heat-sealing layer (3) with an adhesive layer (4).
[0027] The barrier layer (1) adopts aluminum-plastic composite film, which is formed by extruding and pressing aluminum foil and CPP film closely; wherein, the thickness of the aluminum foil of the aluminum-plastic composite film is 15 μm, and the total thickness of the aluminum-plastic composite film is 0.1 mm.
[0028] The base material layer (2) adopts electroless plati...

Abstract
The invention provides a flexible electromagnetic protection jacket composite material and a preparation method thereof. The flexible electromagnetic protection jacket composite material is composed of a base material layer (1) composed of chemical plating conductive fabric, a blocking layer (2) composed of aluminum and plastic composite films, a heat seal layer (3) composed of carbon black modification antistatic PE (polyethylene) films and a bonding layer (4) made of ester soluble polyurethane adhesives. By adopting the technical scheme, the flexible electromagnetic protection jacket composite material solves the problems that that electromagnetic protection jacket material is poor in electromagnetic shielding effect in a broadband range and can not adapt to storage electromagnetism protection of an ordnance equipment jacket under field severe environment conditions, has good comprehensive use performance of being high in electromagnetic shielding effectiveness, small in density, small in thickness, high in barrier property, good in mechanical property and the like, and can meet use requirements of ordnance equipment electromagnetic protection jacket material under the field conditions.
Description
technical field [0001] The invention belongs to the field of electromagnetic protection, and relates to a flexible electromagnetic protection composite material and a preparation method thereof, in particular to an electromagnetic protection composite material suitable for ordnance equipment storage envelopes under field conditions and a preparation method thereof. Background technique [0002] At present, the envelope sealing technology has been widely used in the storage and transportation packaging of tanks, artillery, ammunition and other ordnance equipment and equipment and field cluster storage. Most of the functions of the existing envelope materials are focused on moisture-proof, heat insulation, camouflage, etc., and less consideration is given to the overall electromagnetic protection of ordnance equipment. With the rapid advancement of information warfare, the electromagnetic environment of the battlefield presents complex characteristics such as dense signals, va...
