Abstract

The invention provides an electromagnetic shielding wall plate. An outer wall heat-preservation layer or a decorative coating can further be arranged on the other side of a concrete prefabricated baseplate; the electromagnetic shielding wall plate comprises the concrete prefabricated base plate, a nickel alloy hole net thin plate is adhered to one side of the concrete prefabricated base plate, aplastering mortar layer is arranged outside the nickel alloy hole net thin plate, and the plastering mortar layer is externally coated with a shielding rubber coating. According to the electromagneticshielding wall plate, the nickel alloy hole net thin plate has the great conductivity through the nickel alloy component, a nickel alloy structure is more even through technologies of coarse rolling,finish rolling and heat treatment, crystal particles are not thick and large, a hole net structure meets the shielding requirements, the overall ventilating effect of a wall is achieved, the thin plate has the good hardness, and thus the overall mechanical strength of the wall is improved; and the shielding effect from the low frequency to the high frequency of the wall is overall improved through synergy of the nickel alloy hole net thin plate, the plastering layer and shielding coating from inside to outside.

Description

technical field [0001] The invention relates to an electromagnetic shielding wallboard, which belongs to the field of building materials. Background technique [0002] As we all know, with the rapid development of electronic technology and its wide application, electromagnetic radiation pollution hazards exist all the time. At the foot of radio and television stations in the city, around microwave stations and radar stations, near communication hubs, on both sides of electrified railways, around radio frequency equipment and buildings next to streets, all are areas with heavy far-field electromagnetic radiation pollution. In addition, indoor electrical appliances The generated electromagnetic wave is also a human hazard that cannot be ignored. The walls of ordinary buildings cannot block electromagnetic radiation; therefore, corresponding shielding measures must be taken. The existing technology cannot meet the actual needs, and it is urgent to find a wallboard with electr...
