Description

Conductive cloth with antifouling function

Technical Field

The utility model relates to an electromagnetic shield and absorbing material field, in particular to electrically conductive cloth with antifouling function.

Background

The twenty-first century is the era of information explosion, and the generation, transmission, reception, processing and storage of information mostly need to rely on electromagnetic waves as carriers. The widespread use of electromagnetic waves also results in a number of negative effects, on the one hand, electromagnetic radiation affects the health of humans and causes severe interference to surrounding electronic components and electrical equipment, and on the other hand, electromagnetic radiation causes leakage of important information, which makes computers lack information security. Following air pollution, noise pollution, and water pollution, electromagnetic wave pollution has become the fourth major public nuisance threatening human health.

At present, in order to improve the electromagnetic shielding performance and the conductivity of the conductive cloth for electromagnetic shielding and wave absorption, the surface of the cloth is generally covered with conductive layers of metallic silver, metallic copper, metallic nickel, nickel-clad copper and nickel-copper-nickel, but the conductive layers have the following defects: the surface of the conducting layer of metal copper and metal silver is easy to oxidize and discolor, and the conductivity of the conducting layer is reduced quickly; when the nickel metal conducting layer is used for coating the fabric substrate or other metal conducting layers, the surface is silvery white and is easy to stain. The conductive cloth with the surface coated by pure metal is easily influenced by the temperature and humidity of the use environment, and is easily influenced by hand marks or other contact during operation, so that the defects of oxidation, hand marks, appearance pollution, surface resistance increase and the like are caused.

Disclosure of Invention

The utility model provides a not enough to prior art, the utility model provides a conductive cloth with antifouling function, it has good grease proofing, antifouling, characteristics such as anticorrosive, when having guaranteed electrically conductive and electromagnetic shield function, can also make conductive cloth surface have functions such as preventing oxidation, fingerprint, appearance pollution.
