NOVELTY - Lightweight electromagnetic shielding tarpaulin comprises a conductive base cloth in the middle, an electromagnetic shielding composite material coated on the surface of the conductive base cloth and a light electromagnetic shielding tarpaulin covered on the outer side of the electromagnetic shielding composite material by bonding and compounding the protective film on the outer side of the electromagnetic shielding composite material by the high molecular adhesive. USE - The tarpaulin can have excellent electromagnetic shielding performance, greatly reduce the specific gravity of the awning cloth so as to improve the portability. DETAILED DESCRIPTION - Preparing lightweight electromagnetic shielding tarpaulin comprising (1) weighing the polyurethane raw material and B material according to the weight ratio, (2) preparing glue film by uniformly mixing the polyurethane material of step (1), two components according to the mass ratio, crosslinking and curing at normal temperature, forming continuous, flexible rubber-like elastic film, (3) calendering the composite electromagnetic shielding fabric is sewed on the A-shaped frame; the coating surface by calendaring treatment, the surface is flat, (4) coating the electromagnetic shielding composite fabric after calendering treatment for coating film of step (2), coating two cutters, the speed is 30 m/minutes, the temperature is 170degrees Celsius, the coating is adhered by high molecular adhesive to form a firm composite layer, and (5) drying and shaping the material at 80degrees Celsius after drying and molding.
