Electromagnetic shielding tarpaulin

Abstract

The invention discloses an electromagnetic shielding tarpaulin, which comprises stainless steel metal fibers and polyester chemical fibers. Two fiber card slivers are drawn and blended into yarns, and the yarns are stranded and woven into the conductive high-strength electromagnetic shielding tarpaulin by using a twill weaving method. By repeated drawing of the conductive metal fiber card slivers and the high-strength low-elongation chemical fiber card slivers, the metal fibers and the chemical fibers are fully mixed uniformly and are consistent thoroughly; and weaving of the electromagnetic shielding tarpaulin is realized by processes of roving, spinning, stranding, twisting, spooling, quilling, warping and weaving.

Description

technical field [0001] The invention belongs to the field of electromagnetic protection for preventing electromagnetic information leakage and electromagnetic pulse interference, in particular to a flexible blended electromagnetic shielding tarpaulin for an electromagnetic shielding tent. Background technique [0002] At present, there are mainly two types of electromagnetic shielding cloth developed at home and abroad. One is to coat or electroplate metal conductive materials such as copper, aluminum, nickel, etc. on the surface of the base cloth, so that the surface layer of the shielding cloth forms a continuous conductive surface. The second is to use copper, aluminum, nickel and other metal conductive fibers for pure spinning or blending with other fibers, so that the shielding cloth forms a uniform and continuous conductor from the surface to the inside. Relatively speaking, the production process of coated or electroplated electromagnetic shielding cloth is simple, hi...

AI Technical Summary

Problems solved by technology

Relatively speaking, the production process of coated or electroplated electromagnetic shielding cloth is simple, high in efficiency, and low in cost. The disadvantages are poor wear resistance, folding resistance, and durability, and the shielding effect decays quickly.

The electromagnetic shielding cloth made of pure conductive fiber or blended with other fibers has good wear resistance, folding resistance and durability, uniform material, consistent inside and outside, and stable shielding performance. The disadvantages are complex production process, low efficiency, high cost and low strength index.

From the material itself, copper is easy to rust, aluminum is easy to wear, and nickel is expensive

These two types of electromagnetic shielding cloth are mainly aimed at the radiation protection of the human body and equipment, shielding clothing for human body protection and shielding covers for equipment protection, etc. There is no electromagnetic shielding tent that is suitable for electromagnetic information leakage inside the tent and electromagnetic pulse outside the tent.
